P.4 Prescott 3.2 with p4c800-e deluxe OC help please

[Tat2monsta]

hi.. ill say it now I'm a bit of a noob with the oc thing.
i had a Prescott 478 3.2@3.51 running stable on air stock hsf using the auto setting in bios @20%
just gone to water.. nice and cool setup..and i wanna get this thing up to 4gig or as close as i can either way (above or below 4gig) i have read the sticky about oc'ing manually vcore etc etc.. but I'm terrible at reading and don't take it in too well..(I'm an artist dammit).
at the moe I'm still on 3.51 using the auto setting.. lastnight i was mucking about in bios trying dif things.. and i cant remember exactly what i did.. i know i upped the vcore a little and maybe the ram timings.. but it was late and i was tired.. i should have made a note of every move i did...(will do next time) but i managed to get this thing to boot at 4gig. and it was stable doing normal windows stuff for a while.. surfing/moved a few files to other drive etc.. but when i ran prime95 and tried to run a game at same time.. it waited for the game to go to menu screen then rebooted. i have a sensor..(thermaltake hardcano 10)under my chip. that was reading 38c while this was going on.. in a room with a temp of 28c... my asus MB temp prog said i was at 44c. witch ever is the real temp?. still low for a pressy that was a big load :) so i reckon this thing will go to 4gig and be stable with a few pointers from people on here . i have a q-teq 650watt psu. 2 hd's 2 CD Roms couple fan controllers and a G-card n a few lights running from it. and the air coming from the back of that wasn't that warm.. my air flow is all set up back to front in my system. because i put big rad in the front of my case. i didn't want the thing to get all dusted up. with the fans blowing onto it. so i have them sucking out. and a 120mm in the bottem sucking in and another at the back doing the same. then two 90mm's one in the top blowing out and one next to the psu sucking in onto the hd's. this is in an armor case. i think this setup is also cooling everything that needs cooling on the MB... soz about the rant.. but any help would be very greatfull. specially from anyone that has the same kind of specs

Sounds like you have a pretty good setup there. My advice is to go about overclocking in small increments, so you can check temps and test for stability along the way. You can probably do 3.6 gig with no more than one bump in vcore, so maybe start there at 225 FSB.

[xTrEmEoVrClOcKr]

Either way, your temps are good for a 28c ambient temp (a little warm). What is the stepping of your 3.2e / Scode? (Stepping: EO, DO, CO, Scode: SL7KC, SL7E5 (the ones I can think of). If you have a CO stepping, its not going to be easy making 4ghz. If you have a DO / EO, they should EASILY do 4ghz on water (My SL7KC DO Stepping did 4.1ghz, 7 hour prime stable and benched @ 4.3ghz (Aircooling). It failed Prime95 cause your volts arn't high enough to support the voltage. I would bump it up to 1.45v for now (1.55v would be max for wcing). Also, download CPU-Z version 1.3 to determine the real voltage / mhz. Post some results.

[Tat2monsta]

doh.. you lost me already.. didnt think this was gonna be easy... (What is the stepping of your 3.2e / Scode? (Stepping: EO, DO, CO, Scode: SL7KC, SL7E5 ).. as for the temps i posted.. that was when i had prime and hl2 running oc'ed to 4gig.. but it didnt last .. i was thinking that was very low considering?

soz for being such a noob.. ill learn

[batboy]

He was asking what CPU stepping revision you have. Google and download a free program called CPU-Z, it'll show you what you have. I would bump up vcore one notch and then start again at 225 FSB. If that works good, try increasing FSB in 5 MHz increments until you are unstable again. If temps are ok, then bump up the vcore one more notch. Repeat the process. I would not go much above 1.5v.

[Tat2monsta]

i got the prog you mentioned so its DO?

[xTrEmEoVrClOcKr]

You find out the the stepping through CPU-Z (www.google.com, type in CPU-Z and download it), Under stepping it should say CO, DO, or EO. You can find the s-code on the chip by looking on your Intel Box / actual Chip itself. Focus on the stepping first. :D.

[Tat2monsta]

as for the s-code.. i cant find my box.. i got the useless bit of paper that came with it.. dont say anything on that.. i dont realy wanna take my block off to find it out. the new block i have dosnt let you twist in any way to loosen the paste. it just pulls the chip straight out when you undo the screws..<-- the only thing i dont like about it :(

[xTrEmEoVrClOcKr]

Sweet man, you got a DO stepping. Its probably a SL7KC scode. Try posting @ 4ghz w/ a higher vcore. Switch the overclocking mode (In BIOS) to Manual. Put the FSB @ 250, voltage @ 1.45v (CPU). That will get you 4ghz.

[jjdeltor]

Just so you know, since CPUz says you are running a D0 stepping chip and the chip itself is a Prescott 3.2GHz it means that your chip's sSpec code is SL7E5. Good luck with the 4GHz hunt.

- J

P.S. You may want to check into the forum stickies on dropping the multiplier in your rig as I believe your board (with the correct bios in place) and chip combo is one that can do this.

Edit: Oops, did not know there are 2 possible sSpecs for the 3.2GHz D0 478 pin chip. Learn something new every day.

erm i think thats what i did lastnight.but it didnt last. rebooted when i opened hl2 along with prime. im gonna try again in a minute.. atleast i got some outside help this time.. as for the other thing.. i just managed to get the block off without ripping the chip out.. my new block has a swivleing top.(doh i forgot about that!) it turns 360deg. so i very carfully twisted it and it came off leaving the chip where it should be :) under that i found.. SL7E5 and a few other codes. all have beed writen down.

cheers so far guys.. :)

[batboy]

I used to have that same s-spec and stepping. My 3.2E topped out at 3.9 gig stable.

[ZL1]

... in a room with a temp of 28c... my asus MB temp prog said i was at 44c. witch ever is the real temp? ...

is this air or water ?
asus boards tend to understate temps, you should add about 10C to get more accurate temps
also you mentioned you have a TT probe under your chip, do you mean in between the chip and hsf ???

as for ocing, try 3.8 first see if that works and then go from there
dont forget to set ram dividers (set ram speed to 320 in bios) and to test everything
dual prime for cpu
memtest for ram

ooh well thats what i wanna hear.. i dont have ! to be at 4gig.. i just wanna see how close i can get and be stable..

as for the fsb@250 and voltage@1.45 it booted to a black screen and had my g-card writen at the top. and a checksum error under it. then my temp sensor on the front of my case beeped at me. then rebooted.. it hit 70c for a split second.. its mad i was watching it as it booted. it was around 30c then beeepbeeepbeeep .. anyway, then i tried the same voltage with 240fsb and it said the cards name again on a black screen.. no error this time. stayed at 27c will it did this... so the voltage not high enough? or is there something else i gotta tweek.. or maybe the agp voltage needed a nudge .. as i said in first post.. it booted right up lastnight at 4g but wasnt stable enough to run a game but i cant remember what i changed.. bios is back to default at the moe..

[Tat2monsta]

ZL1 ---> its water.. the temp i get from asus is always higher than my TT one. the tt one is under the chip.and reads on a panel on the front of my case..
like now for instance..
my room is around 23c
the panel on the front says 24c
and the asus one is 34c thats at stock settings.. no OC

34c load or idle ?


D

[Tat2monsta]

in my asus desktop prog it says 34c when idle and on the front TT panel (sensor under chip) it says 24 when idle

[ZL1]

curious, usually these boards understate by about 10C, however your 34 idle with water sounds about right
Id take the TT sensor out as its not doing much, it reads from the outside of the cpu while the asus sensor reads from inside the cpu
and think about it 24C idle with a 23C room ?


D

P.S. howd u even get the tt sensor under the cpu ?

[Tat2monsta]

it has very thin wires that go inbetween the pins on the chip... and the sensor fits nicely in the little gap under the chip.. as for the temps.. ive never known what ones to believe . i know one things for sure the inside the top of the case is room temp when idle and the tubes are very cold to the touch.nice new rad :) the temp i get for the room. is from my mobile that is just sat on my desk .. but back to OC why the black screen with the vid card stated at the top... voltage error?

re oc
did you lock the apg/pci to 66/33 ? very important that you do
also did you set the ram to a lower speed ? once you bump the fsb the ram speed goes up and pc3200 ram wont run 240-250mhz
try running at 3.8 see if it works then go from there

D

[Tat2monsta]

took it to 3.8 manualy by puting fsb to 240 ram to 320 agp/pci 66 66/33 33 vcore to 1.45 and it booted up and crashed when i tried to do anything :( had it at 3.8 lastnight and was in bf2 online for about 30mins b4 it rebooted... ooooh tweekytweeky

hmmm...
what rev is the board ? look at the caps next to the cpu what color are they ?

also watch your psu's rails, see that they dont go more than 5% in any direction
what are the psu specs ?

D

[Tat2monsta]

caps next to the cpu? capasators? got a row of blue ones above the block if that was what you mean

.. rev 2.00

i wish that when you do the auto OC in bios. it showed what was changed. as i said b4 i maneged to get it to play a game for a while lastnight @3.8 and i did this a while ago with the stock hsf.. but i also got it to boot at 4gig lastnight. doing it manualy but wasnt stable.. im sure this thing will get there eventually with some help
p.s clocking it to 3.8 didnt make me any better in bf2.. whys that LOL

ooh almost forgot..psu... its a 650watt Q-Tec triple fan

I asked about the caps as there are two rev2s, rev2a and rev2b which is prescott ready
now rev2a has a bunch of black small caps and 5 green large caps, are you sure yours are blue ? how many large ones ?

when set on auto oc the board simply drops the ram to the lowest possible speed and raises the fsb, volts are untouched
so if you want to emulate it go to manual set the ram to 260 and the volts to auto
or you can just do what you did last night, run auto % then go to win open cpuz and see what it did

D

P.S. I mean what amperage per rail, do you have a link for the psu ?

[Tat2monsta]

psu http://www.qtec.info/products/product.htm?artnr=14348 was pretty cheap..

lol as for the caps.. there purple! not blue.. good job non of my clients come here.. colour blindness dont go down to well in my trade.. there are 7 above the block and then some bigger brown ones.. piks below.. thougt they was blue but got a blue fan by them. and when i used a torch they still looked blue untill closer inspection

yep its a rev2b (large brown caps), so you're good there

this is the only psu that under specs forgets to mention the actual specs :)
the sticker on the side, what does it say ? there should be a line reading your W rating and then ratings in A
also go to www.lavalys.com and get everest, good lil prog, it will tell you temps, fan speeds and voltages
then look at the 12v, 5v and 3.3v while running prime

D

[Tat2monsta]

cant realy see the stiker . my case in the way :( but i can see peak 3.0a and a peak watt 325w.. thats what you wanted eh. i have most my temps and voltages from the last few weeks recorded from the asus probe software..

[ZL1]

the numbers Im wondering about usually look like 30A 35A 20A
check your logs, see what the 12v/5v/3.3v look like, if they are off in any direction by more than 5% you might need a new psu
you can also go to bios and see them under hardware monitor

D

[Tat2monsta]

12v 11.916 - 12.099
5v 5.16 - 5.134
3.3v 3.392 - 3.408
vcore 1.408 - 1.334 this was about 8 pm when i was at 3.8 not very stable thoe

fsb was @ 240 ram 320 agp 66/33 vcore 1.45

as for the lable on the psu i cant see the stuff you wanna know.. thats if its even on there lol.. it sits on its side in the top of the case.. i will take note of everything on the label when its in bits next...for any future referance

[ZL1]

rails look ok
I really dont know what could be the matter ... only thing I can recommend at this time is to go back to 3.6 and go up slowly until you find the highest stable speed

D

[Tat2monsta]

ok. well i got it at 3.7 at the moe did it manualy but havnt touched anything else.. ive been told by a few people that this thing will do 3.9 stable atleast with my spec. spoze i gotta just keep playing with the settings.. theres a lots to mess with :bang head ill stick with it.. im slowly learning stuff.. many thanks with ya help so far :)

its never a sure thing man, some may do 3.9 some may not

you're welcome and if you have any other questions let me know and I'll try to help you out

[Tat2monsta]

wasnt stable at all after my last post.......so

after reading some other posts.. i put my ram frequency up to 235. now my fsb:dram is 1.1 timeings 3.4.4.8 my fsb is also 235 so now im at 3.76gig and seams ok so far..2 hours of intence bf2.. time will tell. am i heading the right way? if it stays stable like this.. to go higher again.. to get the fsb on the ram the same as my fsb. do i have to loosen the timeings more? say 3.5.4.8 <--- just an idea

3448 is as high as you can go
you can try to oc higher, but two things: watch the temps and test using memtest for ram and dual prime for cpu
