FIRST OFF, i think its very important to state two very rough general rules of thumb.
1. a 10% increase in CPU speed will get you about a 6% improvement in overall system performance.
2. A 10% improvement in memory speed (that runs at 1:1 with the processor fsb) will get you about a 1% increase in overall system performance.

so a 10% increase in processor and memory speed gets you about 7% overall performance increase.

for more info on that here'e the webpage

THE PROCESSOR.
people should pick one these options when it comes to the processor.

for 478 pin motherboards

Pentium 4/ 2.4C GHz 800MHz FSB, 512K Cache.............135$
http://www.newegg.com/app/ViewProductDesc.asp?description=19-116-158&depa=1
or
Pentium 4/ 2.8C GHz 800MHz FSB, 512K Cache.............194$
http://www.newegg.com/app/ViewProductDesc.asp?description=19-116-162&depa=1
or (you could get the 2.8 with 1mb cache for cheaper because it performs more poorly unless its is a really high overclock)
Pentium 4/ 2.8E GHz 800MHz FSB, 1MB L2 Cache..........177$
http://www.newegg.com/app/ViewProductDesc.asp?description=19-116-174&depa=1

or
Pentium 4/ 3.4E GHz 800MHz FSB, 1M L2 Cache............295$
http://www.newegg.com/app/ViewProductDesc.asp?description=19-116-177&depa=1

for LGA 775 motherboards

Pentium 4 2.8 GHz, 800MHz FSB, 1MB L2 Cache,..........158$
http://www.newegg.com/app/ViewProductDesc.asp?description=19-116-185&depa=1

or

Pentium 4 3.4 GHz, 800MHz FSB, 1MB L2 cache ..........280$
http://www.newegg.com/app/ViewProductDesc.asp?description=19-116-182&depa=1


the reason for this is that with the 478pin 3.2 and 3.4 C0 steppings , or the LGA 775 pin 3.4 D0, 3.6 and 3.8 any stepping. abit and asus motherboards offer the option to change the multiplier to 14 this reduces the processor speed to 2.8ghz (14 x 200fsb) this allows you to overclock the fsb much higher than you normally would be able to due to the 4.0ghz being more or less the "redline" of processor speeds. although with the 3.8 chances are you will be able to exceed 4 ghz by a fair margin quite simply with the right setup.

abit unlocked boards
http://www.abit-usa.com/news/2004/20041109.php
asus unlocked boards and list of compatible processors
http://www.asus.com/news/2004/20040921.htm

in this list of compatible processors they dont mention that you need the correct stepping...not just the processor speed.

if you want to see what stepping your processor is along with other details specs

you can find your processor specs here.
http://processorfinder.intel.com/scripts/default.asp

if you dont know your processor number you can look it up here
http://processorfinder.intel.com/scripts/default.asp

the reason people want a higher fsb is so that thier ram and processor can have more bandwidth. (ram runs at 2 times the fsb) because if you buy ddr500 ram but leave your computer at the stock 200fsb speed. then the fastest your ram will run is ddr400. whereas if you overclocked the fsb to 250 then your ddr500 ram would run at ddr500 and your processor would be at 3.5ghz
(14 x 250fsb).


PROCESSOR AND RAM BANDWIDTH

the processor fsb is 4 times your base fsb. this basicly determines the bandwidth of your processor. an 800fsb processor has a 6.4 GB/s bandwidth, single channel DDR400 has 3.2GB/s bandwidth (thats where the pc3200 name comes from) whereas dual channel DDR400 has 6.4GB/s bandwidth.
a 1066fsb processor has 8.5GB/s which matches up nicely with the dual channel DDR533 bandwidth of 8.4GB/s (probly closer to 8.5)


RAM RATIOS

it is possible to run DDR533 with a 200FSB with a 3:4 memory ratio if your motherboard supports it some have 4:5 (200fsb ddr500) as well as other ratio options .
though you would get more performance by buying ram that ran 1:1 ratio with your processor fsb with tighter latency timings. or getting a better video card.

its also possible to run your processor faster than your memory. which is what the ratios are usually used for since people are often limited by thier slower memory.


LATENCY TIMINGS

The amount of improvement varies greatly depending on the application you're running, but it's safe to generally characterize the improvement by saying that, compared with CAS 3.0 RAM, CAS 2.5 will give you a 1% to 2% speed boost, and CAS 2.0 will give you 2% to 4%

(for people that like to play halo the lowest latency ram showed a gain of 10% going to 2.0)

for more detailed info see this link that includes benchmarks and definitions.
http://www.extremetech.com/article2/0,1558,1637763,00.asp

-------------------------------------------------------------------------
as to making the decision between the lga775 2.8ghz processor and the nearly twice as expensive 3.4 ghz processor.

keeping in mind that no matter what speed processor you get (excluding the 3.8) 4.0ghz is an absolute redline. people can run past that speed. but not very far and not very often(are people able to get a stable overclock that high).

with that said overclocking your 2.8 processor to 3.724 with a 266fsb is a huge overclock. you are getting nearly a whole ghz more. it is very possible that your 2.8 processor may run out of gas so to speak. and not be able to overclock that high leaving you to settle for a lesser overclock.

whereas overclocking your 3.4 to 3.724 with a 266fsb is a much lesser overclock and chances are that your processor will be able to push that minimal distance.
however. a less than high quality powersupply, motherboard or ram may be a limiting factor in getting to 266fsb.

with abit boards the vdimm voltage (voltage available to give your ram) many times is not enough for the power hungry brand of ram the person chose to run.
a great priced high speed low latency non power hungry brand of ram to get would be as they only require 2.6 vdimm opposed to most 2.8 thru 3.0+
this runs ddr400 speed at the lowest 2-2-2-5 latencies. and ddr533 at fairly low latencies as well.

here is a good review on that
http://www.madshrimps.be/?action=getarticle&number=2&artpage=949&articID=244

many people seem to think ddr2 ram is much more expensive id have to disagree with them

ddr400-ddr533 patriot xbl is 220$

and the DDR2 533 CORSAIR VALUESELECT is 222$ here
http://www.newegg.com/app/ViewProductDesc.asp?description=20-145-526&depa=0

--------------------------------------------------------------------------
some handy information from batboy

"I looked over your list again. It's hard to beat the price of that Corsair Value DDR2... but, check this out.
http://www.newegg.com/app/ViewProdu...-211-128&depa=1
As long as you buy two sticks of the same exact RAM, you'll be fine. They run dual channel no problem. I have tried using dual channel "kits" and buying two of the same sticks of RAM. They overclock almost exactly the same."
--------------------------------------------------------------------------

Motherboard brand selection

there are 2 main choices of manufacturors for overclockable motherboards. ABIT and ASUS.
tho there are exceptions within MSI and Albatron and DFI as well as the occasional other brands. you really should stick to either abit or asus in my opinion.



478pin MOTHERBOARDS

ABIT seems to rule this area of the motherboards being as asus has droop issues with the P4P and P4C 800's

with motherboards for the 478 pin processors there are 2 main choices. the 865 and 875.

if you are going to be getting a northwood processor then the 865 is a fine choice for pricing and options . if you are going to be getting a prescott then you need to go with the 875 without a doubt, sometimes people choose to run the i865 chipset mobos with prescotts these tend to be less desirable because of their smaller power mosfets. and can be a very limiting factor to your overclock.


LGA775 MOTHERBOARDS

i havnt found any eveidence to a clear winner for the ABIT vs ASUS performance for the 925XE But the ASUS costs 100$ more so.... there you go..
.
for the LGA775 motherboard's there is really only one chipset to get when overclocking with a lowered multi. the 925XE.
------------------------------------------------------------------------------

POWER SUPPLYS

as for power supplys. this is the most underrated part in its importance for overclocking. it is imperative you pick a powersupply brand that is know for supplying CONSISTANT power at the rated watts. as many merely list thiers PEAK watts which is nowhere near the amount they can consistantly supply

toms hardware lists 3 brands they would reccomend here
http://www6.tomshardware.com/howto/20030609/power_supplies-18.html

here's a site with great info on picking a power supply for your system needs
http://www.bleedinedge.com/guides/psu_select/psu_select_01.html


the antec true 550 is the premium pick at the moment, however there are 2 versions of it... the 20 pin version and the 24 pin version.

the 24 pin version is the one you want , the 20 pin version has a pathetic 12v rail 24A in comparison with the 36A of the 24 pin.

here is antecs page with the specs and part number for the real true 550
http://www.antec.com/us/productDetails.php?ProdID=20550
and here is the page where i found one with that part number (corrected at batboys advise)
http://www.newegg.com/app/ViewProductDesc.asp?description=17-103-918&depa=0
and here is one thats in stock
http://www.coolerguys.com/840556000563.html
and another one for less
http://www.dttcomputer.com/catalog/detail.asp_id_PS-AN-True550-EPS.html


HEATSINKS AND TEMPERATURE


before i go into which heatsinks you should be getting id like to tell you about the FALSE TEMPERATURE READING you get from ABIT and ASUS.
summed up it goes like this
Abit EQ reports temps anywhere from 7-11 degrees Centigrade HIGH
Abit software reports temps anywhere from 10-13 degrees Centigrade HIGH
Asus software reads anywhere from 5-8 degrees Centigrade LOW

http://www.bleedinedge.com/reviews/abit_asus_temps/abit_asus_temps_01.html



i'd also like to clear up the misconception that if you keep your processor icey cold you can pump all the volts you want into it until it gets hot. this isnt true.

it is true that more volts create more heat and its important for you to counteract that with adequate cooling. and that the better your cooling is the more volts you can put into the processor without it overheating. however the MAX VOLTAGE LIMIT STAYS THE SAME!

you can "FRY your processor" while its icey cold so do some research on your processor around the forums and find the general consesnsus on what is the maximum voltage you should be running!

i will compile a list of this information as soon as i get a chance.
its also a good idea to know what your max cpu temp should be. its normallt in the 67-69 area. but this is redline max. you should be running your computer below mid 50's at least.

you can find your processor heat specs here.
http://processorfinder.intel.com/scripts/default.asp

if you dont know your processor number you can look it up here
http://processorfinder.intel.com/scripts/default.asp



HEATSINKS

last but not least the heatsink is a very important factor in overclocking your computer since this is what keep it cool. you should pick one of 3 options when selecting a heatsink..

aircooled rankings
http://www.overclockers.com/articles373/p4sum.asp
watercooled rankings
http://www.overclockers.com/articles373/waterkit.asp

the thermalright xp-120 is the best aircooled heatsink there is. because with the bigger 120mm fan it can move lots more air with way less noise. the downside of this one being its uncompatibility with some motherboards. you can find this list at http://www.thermalright.com/

but its little brother the xp-90 cools just as well decibal for decibal at high levels (noise level) and is compatible with all motherboards.

i recommend getting this with some artic silver 5 and a high output panaflo fan at
http://heatsinkfactory.com/cgi-bin/HFAstore.pl


coming in 3rd for its ridiculously low price 20$ for the performance you get is the Vantec AeroFlow VP4-C7040 For Intel P4 478 it ranks the same as the 2nd place watercooler with 0.18 C/W http://www.newegg.com/app/ViewProductDesc.asp?description=35-110-008&depa=0

CASE AND FANS

aside from your heatsink and heatsink fan getting good airflow in and out of your case is a must. and the best way to do that would be to get a case with lots of places for fans.
the cheapest one i could find with the most fan slots i could find is here
http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=541440&Sku=D15-1002

it has 7 slots for 80 mm fans and comes with 3 red or blue lighted ones. not to mention it has a large grate on the top of the case which lets you aim all the fans to blow out the hot case air for even better airflow. on top of that it has a clear side panel and overall it looks cool! lol

this goes great with this 80mm fan deal. at newegg. make sure to buy the 15 fans to get the best discount. (free shipping and .99 cents per fan) which cost the same as thier deal for 7 fans.(.99 shipping per fan and .99 per fan)
http://www.newegg.com/app/ViewProductDesc.asp?description=35-150-007&depa=0

this way you wont ever have to buy more fans...(me being the idiot i got the 7 fans without looking at the next deal down...and here i am ordering fans again... where if i had only got the 15 fans i wouldnt be spending 15$ again...)

alright guys. i did some intensive research. on unlockable processors and here are the decisive results
first here is the webpage with the intel boxed processor numbers and specs.
http://www.intel.com/cd/channel/res...ors/int_inst_info/proc_comp_charts/182403.htm

the unlockable 478 pin processors
the 3.2 C0 processor numbers

SL7B8
SL79M
SL7PN

the 3.2 C0 steppings are hard to find but i found 2 places
i found a place that sells it after searching for quite awhile
http://www.jronsite.com/productcart/pc/viewPrd.asp?idcategory=38&idproduct=1077

and if that place ever sells out i found a rather higher priced one here
https://www.ramstore.ca/showproduct.php?id=373



the 3.4 C0 processor number
SL7AJ
the easiest way to tell if its a C0 stepping 3.4 without the number is by the cache.
the D1 have 512 the C0 have 1MB and the M0 have 2MB

the only processor im not sure wether or not it will unlock is the 3.4 M0 stepping but i think it will. so if anyone has one(doubt it) then can you tell me if it unlocks or not.

With the LGA775 processors, you need to get one rated 115w in order to be able to drop down to the 14X multiplier.
the 3.4's in the 115W category are all D0 stepping, in the 84W category they're all E0
so the ones we are looking for that will unlock the multiplier are D0 stepping for 775 3.4

SL7J8
SL7L8
SL7KM

basicly any 3.4 that says 550 without the J on the end with unlock the muti.
as well as any boxed retail 3.4 with the numbers

BX80547PG3400E
or
BX80547PG3400EM

any LGA775 3.6 or 3.8 processors will unlock to 14 multiplier regaurdless of thier stepping.


------------------------------------------------------------------------
so thats it... only those processors will unlock the multi to 14. :)

------------------------------------------------------------------------

i decided to put together a pretty nice overclocking setup for as cheap as possible while retaining the quality needed to overclock. here it is

Looks like you spent a lot of time researching. very nice. A couple comments though.

Get the Abit AA8XE instead of the AA8 DuraMax when using a low multiplier CPU like the 2.8. The AA8XE has a 266 FSB divider for the PCI-E bus which allows a higher FSB overclock. The Duramax only averages 240 to 260 FSB.

Also, while a 20-pin power supply connector will work, with the newer i915/i925 chipset mobos, you are better off getting a 24-pin power supply. I have a 24-pin Antec True 550w which is rated 36A on the +12v rail. The extra 4-pins feed more juice to the power hungry PCI-E slot.

http://www.newegg.com/app/ViewProductDesc.asp?description=17-103-918&depa=1

Maybe check out the regular Crucial DDR2 PC2-4200 RAM (not the Ballistix). It's pretty reasonably priced, overclocks very well, and has fairly good timings.
 
Last edited:
That Ajump website you posted for the Antec 550w is for the 20-pin unit. The newegg link is temporarily out of stock, but they'll get them back in soon (I hope). Make sure you look for the Antec 550W Power Supply, 24-Pin, Model "TRUE550 EPS12V" (linked added to previous post).

As for the mobo, I see newegg is not listing it anymore, but GameVE has it in stock.

http://www.gameve.com/gve/store/productdetails.aspx?sku=MB-ABIT-041

Newegg.com has the Crucial DDR2 RAM too. It's rated as CAS 4, but I've seen reviews that got better timings.

http://www.newegg.com/app/ViewProductDesc.asp?description=20-161-401&depa=1
 
nice! i looked all over newegg and the web for a real 550truepower...and here you go finding it... with the specs all over it! (wishes hes could hug you)

ive changed the links since you told me about them
you were quite right :)

You are quite welcome. :)

http://www.newegg.com/app/ViewProductDesc.asp?description=20-211-128&depa=1

Definitely get the Thermalright XP-90. Not sure what fan you are thinking about getting, but I have an Enermax Blue 92mm adjustable that does a good job and you can lower the RPM to make it more quiet if you are just surfing the net. Crank it to max for max cooling when you are overclocking. I also have the Enermax 120mm adjustable too. Good fans with ball bearings. They move a lot of air on the high setting.
 
As long as you buy two sticks of the same exact RAM, you'll be fine. They run dual channel no problem. I have tried using dual channel "kits" and buying two of the same sticks of RAM. They overclock almost exactly the same.

If you could build this rig with the BEST components.. and money was no object, what would you add, change or replace?

Im at a toss on the Abit and Asus Boards for the 775. All my boards are Abits..
 
to make a long story short if you wanted all "top of the line overclocking performance" you would be spending around 3100$ to get an extra 25-50 fsb if you got lucky plus an extra gig of ram. and a hard drive for your operating system to run on that had a 3.3 seek time instead of 4.5 from the 74 gig raptor. and a video card that doesnt perform at a level worth 600$ if you ask me. if oyu want that much video power buy a sli board and put 2 video cards in it.

but anyway heres the list.

the asus P5AD2-E for the motherboard.

a 3.8 processor.

a 15000 rpm scsi hard drive with a scsi card

X800XT PE video card

2- 1 gig chips of high performing (overclockable) 533 ram. in order to run 1:1 ratios

then the rest would be the same due to the XP-90 or xp-120 being the best aircooled heatsinks and i dont like messing with water.

and then you could pick out your dvd burner of preferance ... i like the plextor 712SA but thats just my preferance due to my prefering 8X dvd's and i dont like dual layer dvds cause they are way over priced

and then you could pick out your dvd burner of preferance ... i like the plextor 712SA but thats just my preferance due to my prefering 8X dvd's and i dont like dual layer dvds cause they are way over priced

Can you give an example of the ram?
These video cards are scarce!
SCSI is a good idea!!!!
I wonder why in your other posts yoou pick the Abit over the Asus? Is it a price thing. I only use Abits right now. But the Asus has the extra PCI slot and slightly better performance..
 
for the most part abit kicks asus's butt for overclockability. since the asus 478 p4p800 and p4c800 have vcore droop issues. but in the case of the top of the line overclockable lga775 asus wins. but only in slightly better performance... in price/performance abit wins.

as for the overclockable ram. im not a guru when it comes to picking the best ram that will easily overclock past its spec.
however toms hardware states geil should overclock fine from 667 to 711 so i dont doubt the 533 would overclock ok as well. but now that i look at the price difference between the 2 gig of 667 and 2 gig of 533 from giel. its only 35$ difference.. so i would without a doubt pick the 667 and hope i got lucky and it would overclock enough for me to run it at a 3:4 ratio at 280fsb. and if not then settle for 1:1 at 280. either will be good. the signifigence of buying 1 gig chis insted of 4x512 is that sometimes with 4 chips the bandwidth you get is affected negatively... and that would be self defeating. although i have heard that with some boards 4 chips perform better... so its a toss up.
 
Thanks for all your research... I agree with you on the Abit Vs iAsus on the 478 side especially!! Like I sated I am a devoted Abit user but may defect to ASus (still not completely decided) for my LGA board. I am in total agreement about the RAM. Now which motherboard of Abit is the best choice of the 925s chips. I see you choose the
AA8XE 925XE which is my favorite in the group. The Fatality has some appeal and potential see TOMS REVIEW
Any thoughts?
 
fatality is just pretty looking and has plenty of features...at least thats what i recall batboy saying. however if you want to decide on a 925xe board the decision is between the abit and the asus boards we have talked about.. get the fatality if you want features.
 
well i have seen alot on the best ideas of a system that might be best but noone as so far are built on the 775 chip.

i followed this thread,

man i still have a head ache

there are alot of things to take into consieration since these newer chips are so power hungry

on this thread from woutertal he shows the mods he did to his board (478)

from what i have read it seems the mother board makers are taking this into consideration and adding more power available on board, but not the psu companys yet-- yea i have seen a few with adjustible rails but the power from the psu will need to probly double wit todays standerds from us now mating two of them

cooling i feel is always going to be a choice of money available, so as to their prefrence

i was going to upgrade to a 478 (from what i have) but decided that the newer pci-e was the way of the future ( not so available on older boards)

stepping a cpu on the 478 i learnd when i read the threrad above but i do not know if it still holds true for the 775's- stratcat had posted that all prosseors with the steping to 0 would not o'clock... i just finished that thread and am looking for new info

i am by no means smart at this yet ... just give me a min..........
