need help OCing my new rig (Q9550)

[shaffaaf27]

got an E0 Q9550 from ebuyer, and a maximus II formula, and watercooeld it.

under OCCT my max FSB i can get to pass is 467, but game crash within seconds....

these are my voltages:

(btw temps under laod never go above 50 on any core)

I've already helped you in the Maximus II formula thread. Here's a copy/paste of what I've said there:up: :

Get those voltages off of auto! The maximum safe CPU PLL voltage is considered 1.6V. 1.7V is already quite extreme. Yours is at almost 1,8V Also, I wouldn't go over 1,45 VTT. You're getting close to this value, as you're already at 1,44v. I am using just 1,3v at 8,5x475fsb. Put your CPU and NB clock skews on normal (not auto!) and test if you gain any stability. Also try out (100ps delay on CPU with normal on NB) and (normal on CPU with 100ps delay on NB). Out of these 3 possible combinations, pick the most stable. Set your VTT to 1,4ish. You can back this voltage off later. vNB at 1,45 is indeed a good start, but you should try to get that one down later one, once you get your setup stable. Now you should SLOWLY increase your FSB. You shouldn't have to increase any voltages to get it stable. (you might need up to 1,45v Vcore to get 4ghz stable, though)

Set your NB GTL reference voltage on auto and set CPU GTL reference voltage on auto on all 4 options. While you're working up on the FSB you'll notice cores failing in prime95. Take note of which cores are failing. If core 0 or 1 fail, you'll have to play with CPU GTL reference 0 and CPU GTL reference 2. If core 2 or 3 fail, you'll have to play with CPU GTL reference 1 and 3. Note: GTL reference numbers do NOT represent cores. 2 cores on the same die use the same GTL voltage. Both dies have 2 different GTL voltages. One for the address bus, and one for the data bus. For now, always keep GTL 0 and 2 the same. And keep GTL 1 and 3 the same value too. So you'll have to figure out 2 values. 1 value for both GTL 0 and 2. And one value for both GTL 1 and 3. You can finetune them seperately later. Getting cores stable with GTL is purely trial and error. Every single CPU responds differently to different GTLs, and even different boards have different amounts of vDrop on the GTL lanes. Just trying anything ranging from -70 to +70 till you get all cores stable again, and start moving up again on the FSB, till cores start to fail again. Then you have to tune GTLs again, etc etc

Edit: Use small FFTs to test GTL reference stability in prime95.

cheers mate. tried the first 3 options, still crashed cod4 at 475, ill try 467 in cod4 to see if it works. sorry to be a pain in the arse, btu can you link me to rime, never used it before. my E2140 1.6GHz went to 3.4 no problems on my P5K-E, im just bamboozeled as to why under water an E0 Q9550 cant reach 4GHZ :(

It's not worth it trying to figure out whether your overclock are stable by playing games. You'll just get annoyed by the crashes all the time. Also, 4ghz on water is quite possible (I'm using a q9550 C1 at 4ghz, AIR :p:), but overclocking quads is quite a bit harder than overclocking dual cores. It takes a lot more finetuning. With my current overclock, if I increase the GTL on channel 1 or 3 by just 10mV, I crash within 10 minutes. Without it, I'm perfectly stable for hours. If the skews didn't work, I'd leave them at "normal" (not auto!), but if you can't get it stable with GTL tuning, try the above mentioned skew tweaks again. Also, don't start so high on your FSB. Try to get 425 stable first, then move up to 450, then to 460, 465, 470, 475. It takes a lot of time. It took me over a week to get this q9550 stable at 4ghz. And while I'm certainly not a fantastic overclocker by any means, I do think I have a fairly good idea what I'm doing. If you're having trouble with a FSB jump, don't be afraid to take even smaller steps (2-3mhz at a time is far better than large jumps, without knowing what the hell is causing the instabilities). Try to get each FSB step stable for atleast 15-30 minutes small FFT in prime95 (linked above). Don't fiddle with voltages too much. You should have plenty of power for now. Fiddle with the GTLs and if needed, have another go at the skews if GTLs alone can't get it stable. Good luck! :up:

Edit: Once you get 4ghz, use prime blend test to test it for atleast 6 hours (more is better, I'd say 12 hours, maybe even 24). Use small FFTs for now. Also, use a 1:1 ram divider, so your RAM won't bottleneck your overclock. You can increase the RAM speed later on, when you're sure your CPU is stable.

mm cheers, well im stable upto 465 on all auto as it is.

yes i know i hsould see if prime is stbale, but i did OCCT for 2 hours, mix test, and all was fine but 1 min of gaming and boom lool.

467 with 100 delay on the CPU and normal on the NB allowed me 5 mins of gaming, but then a crash, ill try it the otehr way around now.

thank you so much mate, honeslty, if i could hug you i would :)

[shaffaaf27]

:(

467 the NB 100 cycles stays 10 mins on cod4 but still dies.

here are my new voltages.

Cpu on normal, nb on 100.


ill try prime now, any special settings?

[spoof]

Do you have so called lockups in idle and under loard? Try some 3D test, like 3DMark or Furmark, just to get your card under load. If it crash again, you have problem with PSU or you didn't lock you PCI freq to 101. Try rising the vNB to 1.49 too.
And lower this CPU PLL and FSB VTT voltages. You don't! need more than 1.56v CPU PLL and 1.38 VTT. And what do you get, when the game crashes? BSOD, send/don't send, error, what?

[shaffaaf27]

lowered PLL to 1.5, VTT and NB to 1.4 and Vcore to 1.4

added 10mvs to the NB GTL ref, allowed me alot longer of cod4 time.

furmark doesnt crash, 3dmark does, but during the CPU tests. and ati tool shows no errors on its GPU test.



lock ups are only under load, but under idle, once or twice some programs dont load up and are unstable liek vuze, or itunes.

no bsod, jsut an error and it tells me to close down. let me play and get the exact error

[shaffaaf27]

iw3mp.exe has stopped working, windows is lookign for a solution....

[shaffaaf27]

prime95 for an 1/2 hour no problem.....

and its not just cod4 its all games...

[Hoss331]

Maybe this will help, to get 467 stable on my C1 I use 1.325vc, 1.54pll, 1.30vvt, 1.32nb, cpuGTLs .640 and nbGTL auto. For 471 it just needs one bump in vcore to 1.33125. I dont know your full setup but to me it looks like your way over volting everything, which may be your problem. Lately ive been trying to get 483 stable and sometimes just upping voltage will fail prime sooner, mainly when I dont have the gtls set right.

[shaffaaf27]

tried that, mate didnt work :(

[shaffaaf27]

put multi to 6 at 467, 1.4 for CPU, VTT, NB and 1.5 for PLL.

disabled speed step and CE1 etc etc etc, btu its still shows 8.5 on cpu z....

[shaffaaf27]

took it to 458, no problems at all, low voltages aswell.

but even 1 fsb over i crash in games.

is this a mobo OR CPU wall?

I bet it's the mobo, because playing with CPU PLL should move CPU wall(if there is any) at least with 1mhz.

[shaffaaf27]

updated to the newest bios now, got 470, 3d marked, OCCT passed, and 2 hours of prime, BUT about 3 seconds into cod 4 crash, and GTA and crysis etc etc.

Actually, i had the same problem. I'm sure, that more vCPU will fix the problem. I'll test tomorrow, because when it started to crash i lowered the FSB to last known good. The same thing here. OR it maybe RAM related - try with 1:1 or 6'es on the clocks.

I wouldnt think so, got to be something in your settings.

i am using 1:1 and i have 1066MHz ram so its under rated speed, put it at 2.2V and have loosened the timings to 666 18.

put both clock scews on normal.

1.45 on the Vcore, 1.65 on PLL, 1.4 on VTT, 1.4 on NB, and GTL 1 and 3 are -45mv and 0 and 2 are on auto

after i crash in any game, i try OCCT again and i fail, i tried manual settings, CPU will pass, but RAM test fails within a minute. memtest the RAM and its fine. im sure its the NB.... i replaced the TIM with OCZ freeze aswell.

3damrk is fine at 470 but gaming isnt, i have to go back to 458 for gaming :(

shall i take pics of all my settings?


are there any good modded BIOS's? im on 1802 ATM, i will try another bios in the second bios chip i have

go for it

Try set CPUGTL with "+" instead of "-". And lower you CPU PLL, more than 1.58 causes lockups. Disable C1E and load calibration too, sometimes this is the problem. PCI-E freq to 101 and set OC from CPU level up to auto. Try set x63 to NB GTL too.

[SNiiPE_DoGG]

over 1.45vtt is safe, dont listen to these worry mongers. you need a high vtt for most quad cores to be stress stable

thankyou seban for that

You welcome m8 :). Keep it going :up:

umm.. but its still just 470 FSB :eek:
Glad that you got it stable :up:

[Leeghoofd]

470FSB is where he's at...

What did the trick ? bit more NB voltage, SRC disabled ? the GTL values ? Mix of them ?

[seban]

I am pretty sure it is just gaming stable (to the time it will get unstable ;) ) - I do not think that he did proper stability test.
