3.0 Best E Or C

[syberspy9]

im going for the 3.0GHZ P4 and im thinking get the E over the C its 10$ more and it may not out preforem the C very well or at all in some apps but it seems to be the better chip for the same price i mean it does have new teck in it even thought the C is a GREAT chip

and with my sp94 im not worried about the heat to mutch as long as its under 50C

[jpm804]

I would go with a 3.0c , you have better luck hitting a higher speed. Looks like people have been hitting 3.7ghz easy with the 3.0c lately (look at sig). Not unless you have watercooling or better cooling you might not have such good luck with a 3.0e. my 2cents...

[Lancelot]

"and with my sp94 im not worried about the heat to mutch as long as its under 50C"

Man that thing already defaults to 55C on good air!!!

[syberspy9]

stock with my sp94 what will my temps be???

[jpm804]

I have a sp94 also with a 92mm fan pushing 78cfm...idle temps at 47c and load at 56c....

[jenkx]

Go for the E. Why not. It's very fast. I have the same motherboard as you. As long as you have the fsb to push it it will overclock fine. I water cool and I only see a 2-3c difference in idol temps from non-o/c to o/c.

If you don't water cool it will run hot, but thats what it does, its a prescott. The heat won't kill it. It's like a fish sucking in water, that's what is expected of it.

[deathstar13]

id say the 3.0c myself.
i have both 2.8c and 2.8e i prefer my E on a prommy and the C on air.
the E doesnt pass the C chip until 3.4-3.5ghz performance wise.
and anthing past 3.5ghz on air i think is pushing an E to far with that much heat.

on air i saw a 10C differance idle in temps and at load 15c

[syberspy9]

i want the 3.0 @3.5 E
so thats what im getting why not a bit of heat so what it wont melth the thing
I WANT THE E AND IM PROUD TO SAY IT

[deathstar13]

its a great chip no doubt.
but dont be suprised seeing 68c-72c @load tho.
never hurt mine tho,plus my mobo over stated temps by 10c
anyhow if you ever go h20 or better cooling the chip will fly.

i can do several settings on mine:
3.7ghz 1.39vcore 1:1 265fsb almost sure its stable
4ghz 1.49vcore 5/4 ram

i stay with my 1:1 settings as the memory bandwith helps over all performance more than mhz alone.plus i can do it with less vcore.and trust me .1 is alot when concerning prescotts.
on air you will need more vcore to make it respond,my cooling makes lower voltages work better.
took me 1.55vcore to run 3.7ghz on air.
now 4ghz at 1.49vcore,so cooling makes the chip better.

also in the 1m super pi thread in the combined cpu forums here my 3.7ghz scores are among the highest here.
so the pressy is a good chip.

and be carefull ive been accused of being called a prescott fanboy.even tho i suggested you buy the C.lol

[Captain Newbie]

The lengthened pipeline of the Prescott (E) (31 stages vs. 24 stages for Northwood C) means that the Prescott has to clock higher and therefore put out more heat to run comparatively to a slower-clocked Northwood C. It's just like when Willamette came out--the lenghtened pipe resulted in the Pentium III and Athlon Thunderbirds kicking the P4 Willamette's rear until they hit something like 2.0.

*shrug*

Prescott only if you've got some excellent cooling.

But the final verdict for me is...Northwood simply because it is tried and proven and known to scale well up to 3.6.

[syberspy9]

well the E will do fine with my sp94 and a vanteck stealth (or mabey a panaflow)
but if i have to ill keep it at stock untell i get h20

im shure ill get to 3.5 on my air if not w/e its all good 3.0GHZ and a 800fsb and my ddr400 ill love it comparide to my 2.4B that runs stock cooling @2.6 and make my ddr400 go down to ddr333

[Osirus]

Well my 2 cents on the subject is go with what you can handle cooling wise.
I have a 3.0E oc'd at 3.6 on water, idle temps are 44c load temps 55c or so.

I would go with whatever your cooling can handle.

[syberspy9]

well the cooling issie is the only problim

but it is a big one
man ok so if i get the 3.0GHZ C then i oc it to 3.5 thats fine but how mutch of a disadvantege will a 3.5C have to a 3.5 E????

what is the point of a E if a C is just is good

[deathstar13]

about 1-2% differance if that at 3.5
its not big as its the 3.4-3.5 when the prescott starts pulling the larger numbers.
i see NO reason you shouldnt get 3.5ghz on air.
i had to back down to 3.4ghz since i was folding and was too hot for me to feel comfy at 3.5ghz
wasnt the cpu complaining but me.

teh point of the E seems to be aimed mainly at people folding/seti and xtreme cooling people h20 or better.
the E tends to scale better whith better cooling than the C does imo.
throw one to 4ghz and stand back too.

i love seeing peoples astonishment when they see thier new high costing a64 just got spanked by a p4 lol

[Osirus]

I picked the 3.0E for the reason I want more power for the long run, I like the 1mb cache as well, it does help when doing alot of video editing, which is what I do 85% of the time im on the comp. Cooling is number 1, get some awsome cooling and decided what you will get.

[syberspy9]

well will a 92mm stealth fan on a sp94 cooling a 3.0E@3.5 be enuff??
what will the load temps be???
im a gamer thats about it and i surf the web
i used to use MAYA 4.5 lots but now im gaming and on the web thats it
so will the 3.0E@3.5 with the sp94 and the vanteck stealth
be cool ennuf to run a 3.5 and be stable i donta wana make my cpu 65C (IF THE LIMIT IS 70) /ON LOAD/

[deathstar13]

people with the prescotts tend to be real picky on wanting to know their mobos over/under temp reporting.
that asus under reports if i remember right.my epox over reported by 10c.
so i was seeing 69c-71c folding.
probley 59-61c tho.
i was useing an alpha 8942 with a 90mm HO fan

id say its gonna be harder to get 3.5ghz with a prescott on air as it would a C.
but imo should do it.

if seeing high temps worry you DONT buy a prescott.and if you plan on staying on air and want to oc the highest you can the C is for you.
i knew i was going with chilled h20 or a prommy when i bought mine.

just to put things in perspective ive seen reports of highley oced prescotts bringing machI and plain vapochills to their knees. +20c temps!

i dont want to discourage you are make you change your mind but i wanna set the pic as clear as i can for you,so you dont feel you made a mistake later,or that i led you wrong.

if you can get past looking at higher than normal temps your fine tho with the E

[syberspy9]

is this true (with stcok cooling) how mutch will the sp94 and my vanteck steal drop the temps with some as3?

[syberspy9]

well i found lots on google and i have to say sorry presscot your just to dam hot
(LOL)

any way the heat isant worth it imo and im on air so its a big deal for me
finnally im getting the 3.0C and a sp94

at
www.ncix.com
ill be back to tell u how it is and if it was the right choice or not ill order it tomorow

[lemon]

Presscott stresses mobo, the presscott increased the P4C800-dlx mosfets to 70c+ that is very hot although the mosfet was designed to operate normally in such temperature but, it will shorten the lifespan of mosfet and power regulator caps on mobo.

ill be back to tell u how it is and if it was the right choice or not ill order it tomorowi think you will ge happier with the C,both chips have thier strong/weak spots that make each one great at what it does.
i think you may actually get the C higher oced than the E with the 3.0

lemon- you are correct my man,these 865/875 were not designed to carry these loads the E's place on the mobos.
shorten the life? i dont know about that but possible if you let thing get outa hand.i use ramsinks on all my mosfets.

i did fine one good thing about my ic7 and my prommy is wherever the pwm is located its around that 4" square my evaps head covers.i coat everything with dielectric grease so air stays out but also so the super cooling spreads threw the grease and cooling the pwm.
mine reads 0c idle 12c load.
just a great side effect i didnt expect when i bought my prommy.

[syberspy9]

well with all the new stuff coming out i want to save up so next year in like FEB.
i can get a kick ass sytem so for now im going to trade my 2.4b and some cash for a brand new 2.8C from the local comp shop guy
then i think oc it to 3.0 on stock cooling and leave it at that
once i sell this sytem (ill sell it on my birthday DEC. 24) ill get cash wait 2 months and then ill have a killer sytem 3.0C on stock cooling it might cost me 100 max probibly lie 20$ once i trade in the old cpu

no ill get the sp94 cuz i hae 70$ credit at that store sweet so i might pay like 20$-50
for a new cpu and sp94
ill go talk to the guy tomorow

[syberspy9]

well i got a 2.8C

http://processorfinder.intel.com/scripts/details.asp?sSpec=sl6z5

im stock no oc yet and im running a sp94/ vanteck stealth
30C idle no load temps yet

*edit* load temps are 44C running prime 95 24hr's

[syberspy9]

well i just oced my 2.8C with my vanteck stealth (that only pushes about 25 cmf maxed out and i bet it was just pushing 20cmf while i was ocing, but didnt wana put that tornado on, its a bit to mutch noise (seriosly just a bit if it was like 10db less i would have it it).

well i pushed my sytem (SEE SIG.) by only upping the fsb i didnt use any thing else no vcore nothing just upped the fsb and checked temps.

i started at the stock 200 fsb first i knew i could jump it up way more, so i upped the fsb rigth away to 240fsb (3.4GHZ 36C idle 50Cmax) then so on.

i got my fsb up to 250 and it wouldnt post so reset the bios and then the next time it wouldnt post was 250fsb (this is with all stock settings exept fsb!

so right now with only jumping the fsb i can make it to 3.522GHZ 36.5C idle 51C max.

imo thats great oc for just the fsb and a 20cmf fan on my sp94.

the thing i need help with is when i got to 255FSB IT REALLY WOULD POST,
but once i got into the bios my bios just beep'ed like crazzy (beep,beep,beep REALLY FAST LIKE THAT).

what made it do that not enuff vcore??? the temps were only 36.5C in the bios (i cheacked really fast then shut down ALL IN ABOUT 2SECONDS FLAT).

*edit* cpuz sais my stepping is 6 and myrevision is MO
model 2 ,family F, brand ID 9

[deathstar13]

id put the tornado on if you wanna push the system.not useing it and hard ocing is just isnt gonna mix well.

the bios is freaking out for 2 possible reasons,not enough vcore or ram needs more vdimm and or relaxed timings/lower fsb.

3500mhz on default vcore with a 2.8c definatly is gonna need more volts.
should clear it up tho.

btw mine did this a few times and my speakers were up loud and i about jumped str8 outa my chair! funny as hell :)

[syberspy9]

lol same thing hear i was playing bf vietnam to test the oc out at 252fsb then i had the speackers up to 4/8 (so so loud) and then i jumped the fsb to255 then my bios just freaked lol.

well i have the mem timmings at stock right now.
vdimm hey ill look for vdim in the bios dont know any thing about it but ill only up it 1 setting

[deathstar13]

vdimm hey ill look for vdim in the bios dont know any thing about it but ill only up it 1 settingshould be fine,usually its warrentied upto 2.8vdimm in most cases.ive never heard anyone fry one at 3v even but you may not need to do it after the vcore is adjusted,im rather sure thats whats doing it tho.

[syberspy9]

ok i am ready to jump up the vcore 1 setting but i didnt see any vdim whats it called in th bios??

[syberspy9]

ok well i jumped the vcore up and now it doesnt freack out but it wont go into windows it loads right were i log into windows then reboots itsself

as im posting this im running 3.4GHZ 242fsb 33C idle (with the vcore still up one setting)

but get this once i jumped the vcore up and boosted my fsb to 255 and it posted i when to the bios and checked temps there now at 33Cidle before i jumped the vcore they were at 36.5C man evry time i oc this thing and it wont post then i reboot and re cet cmos it gets better lower temps higher fsb man this thing is the best cpu!!! and im a oc newb lol think if eobard had this cpu man that like 4GHZ on air if eh was tunnning this thing

[deathstar13]

im trying to stay focused here sorry im helping several people at once all with differant rigs and im getting confused lol.

if you not useing the 5:4 devider on the cpu you should be with 255fsb as i dont think that ram will do much more.

you can work on ocing the ram seperate later and setting it back to 1:1 with best timeings it will do or run 5:4 with low timings.

[syberspy9]

i think im going to keep this at 3.4 for a bit untill i prime95 it for 24hr's

[syberspy9]

ok well i have had this thing at 3.2 (i wanted to keep it there raher than 3.4)

im running it only by FSB nothing else

so now before i bump it how hight sould i go (MHZ)

at what FSB do i need to change the Vcore (and what do i set it at???)

what is with all the other voltages and do i keep them stock???

now i need some help

[syberspy9]

mabey i should start a new thread and delete this one???? yes or no??

[deathstar13]

mabey i should start a new thread and delete this one???? yes or no??
keep the thread,intel land just has slow spurts.
my daughter is here,but asleep so i can sneak some time online.

you can go upto 1.65vcore and what ever fsb it will handle.im guessing you will max out 3.5ghz -3.6ghz tho.

Presscott stresses mobo, the presscott increased the P4C800-dlx mosfets to 70c+ that is very hot although the mosfet was designed to operate normally in such temperature but, it will shorten the lifespan of mosfet and power regulator caps on mobo.

I second this all the way. For those above who think the PresHott's heat is harmless. Wail till you end up with one, overclock it and then watch it take the life out of your motherboard. I had a 2.8E @ 3.8 using 1.55v, this was the first two days. On day three, went ahead and tried 3.9 running 1.6v. All this is on an Abit IC7-G MaxII. Well, it booted, ran a couple benchmarks, then shut down faster than I can say "WTF". The result?, my mobo released a distinctive scent that we all know. I then slapped the PresHott into my P4C800-E, worked fine.

With water, I remeber thinkin' "This can't be" but ya, that processor/furnace is just not practical for overclocking IMO at least without phase change. Good thing you went with a Northwood Syberspy :thup: , I did the same thing.

By the way, I had Tweakmonster ramsinks on every mosfet and couldn't touch em for more than 2 seconds.... sizzlin'.... :eek:

[syberspy9]

ya i was maxing out at 3.6 but i had to have more vcore i just didnt want to jump it to high cuz i dont have hs on my moffits i need some that will fit.

but i have to say 3.2 is so stable!!!! it feels like the stock mhz its not even hot!! 27C idle rightnow

[Myhre]

Seeing everyone getting procs that OC to 240+ like it's nothing almost makes me wanna cry(well maybe not). I had a 2.8C that wouldn't go past 235FSB no matter what and then I upgraded to a 3.0C that wouldn't go past 235FSB. All I know is you guys better start thanking me....because me and my bad luck are whats weeding out all the dud processors so that you guys can get the uber ones. /golf clap for me :clap:

[Osirus]

its not the CPU, its either memory or motherboard

[syberspy9]

no way Osirus

my mobo look at my sig. its the BEST

and my ram isant even warm and i have it on stock timmings

[vkvenom]

you luck got a good chip ! my 2.8C will not post over 237 at all.tried every thing !

NIce !!
ok well i jumped the vcore up and now it doesnt freack out but it wont go into windows it loads right were i log into windows then reboots itsself

[Myhre]

its not the CPU, its either memory or motherboard

Where you talking about my proc or his? Either way, I'd say a CPU has a lot to do with the overclockability of a, you guessed it...CPU. In my case I'm running Corsair3200XLPro sticks....which can run at 1:1 up to 500mhz. And I had previously tested them at a 5:4 ratio, which takes the memory out of the picture. And as for the mobo....P4C800-E deluxe...the best Asus has to offer atm.

[syberspy9]

thanx vkvenom.

and Myhre yes ur right the mobo is not the problim and i dont think its my ram cuz like i said its not warm and its at stock timmings.

so could some one tell me what all the othr settings in the bios are for??? as for ocing what else do i need to set?
