q6600 3.0 overclock trouble

[kayvon]

I have a problem with my overclocked q6600. Currently its at 3.0 ghz from 2.4. Everything starts up fine but a couple games of mine started crashing and one game even gave me a BSOD after i exited it. What im wondering is if its my q6600 or if it has to do with something else, like my memory or something. Any ideas? Also, STEAM was having problems at start up.


SPECS:
Q6600 OC 3.0ghz
Evga 8800gt 512
Freezer pro 7 Ac
Antec Neopower 550 watt
OCZ Sli Ready DDR2-800
Windows Xp sp2
680i Lt Sli Board

Oh and i have 2x2gb memory.

 

[Maziar]

Have u only increased the frequency to 3.0GHZ or u have done other things like changing the voltages,......?

 

[doomturkey]

Yeah. Download coretemp, tell us your VID. You are going to want to set voltage to your chips VID or higher, then see if that helps.

My Q6600 runs 3ghz without a voltage change (running at VID), 3.2 ghz with a little extra juice. This is on a P45 mobo. I haven't tried any higher yet, but 3ghz should be easy for you, even with that nvidia mobo.

 

[kayvon]

Yeah My VID is 1.2500v on core temp.
But in the bios its around 1.37

Grab CPU-Z and make sure the board did not push the memory too hard

http://www.cpuid.com/

Many boards run the memory at its default speeds at stock. then when you push the fsb the memory jumps too. this can lead to the problems you mention.

 

[kayvon]

very weird, other im reading it wrong or its messed like you said.

Dram Frequency:400.0 mhz???
FSB😀RAM 7:9

Isnt the fsb:dram supposed to be 1:1 could this be the problem?

 

[rockbyter]

if your processor is at 333 bus, and memory at 400, try 1 to 1 and it'll take your memory down in speed. might fix you right up.

 

[Maziar]

Have u lowered the memory frequency to the lowest option? (for example from DDR2 800MHZ to the lowes option availabe?)

 

[kayvon]

So what you guys are saying is to reduce the memory speed in bios to 400? Cause right now its at 800

 

[nukemaster]

Running out of 1:1 is not always a bad thing. 400 should not be enough to cause instability. What are the timings like.

Are you running 311 and not 333? that would give you those timings

Did you manually set the memory voltage to the manufacturers specs?

There should be an option to get 1:1 in the bios. it may be worth at least trying for testing to eliminate that as a problem.

Running out of 1:1 is not always a issue

 

[kayvon]

ya i underclocked it to 2.8ghz and it seems to be running fine. But at 333 its starts to mess up. No i didnt set the memory voltage its at auto right now. So i should go back into bios and set it back to 333 bus speed and set it to 1:1?

 

[kayvon]

Ok, so i went into Bios. Changed the Bus speed to 333 and changed it from unlinked to link and set it to 1:1
However when i saved and exited it didnt say 3.0 ghz on the startup page but 2.4 stock speed. the FSB was also set at 1067 instead of 1333 on the start up page? any ideas?

 

[aznguy0028]

yea i would try that. set 333 fsb. and ram to 667mhz. that should be 1:1. if i were you, i would try to set voltages on auto for now, to see if your computer runs stable first on auto voltages. if you stop getting BSODS, then you could manual set your voltages to what you want. although auto voltage sets your voltage higher than what you need to for OC-ing, it still should be within the safe limits of your processor, the temps will just be a little big higher, but tolerable. make sure all the settings are correct, such as C1E and EIST are OFF. good luck, report back to us on how your comp runs.

 

[Maziar]

Thats right,set it too 667mhz and it will be 1:1,but dont set the voltages to auto,setting to auto may cause instability.

 

[aznguy0028]

Thats right,set it too 667mhz and it will be 1:1,but dont set the voltages to auto,setting to auto may cause instability.

i just wanted your opinion, but are you sure? there are a lot of voltages that may require tweaking in OC-ing. the CPU voltage, DDR2 voltage, NB/SB voltage...etc etc and any of those that are insufficient, you would probably get a BSOD.

i was suggesting auto voltages just for now, to see if he gets any more BSOD's, cuz if he did, that would mean he messed up the manual voltages somewhere. although auto voltages are often time overestimated, they still fall within the safe range of the computer hardware. i do agree with you that if he can, he shouldn't leave on auto voltages, but for now this is just to narrow down the variables of what is causing his comp to bsod.

 

[kayvon]

Ok aznguy i did what you said and so far its all good. Games are running fine no blue screens of death and my cpu temp is about 29C
voltages on auto. But ive noticed in crysis that there were some choppy buggy stuff that werent there before. I want my cpu at 3.0 but do i have to sacrifice my memory speed to do it?

No,u dont need to set all voltages,many of them should be Auto,but some of them like Memory voltage and CPU voltage should be changed for getting better results.

 

[aznguy0028]

ahh okai...i see what you mean now, okai i agree with that.

 

[iluvgillgill]

i think the best thing for your cooler is to use multiplier 8x and up the FSB to 375 with 1:1 memory multiplier. and up the memory and vcore up 1 notch each and it should be fine, and stay with your 4-4-4-10 timing. 3.2Ghz will be very hard on the cooler. if its lapped then 3.2Ghz might be possible.but unlapped CPU and cooler i might call it impossible.

can you give me your prime95 25.6 small FFTs load temp?

 

[kayvon]

hmmm ill try it, and youll have to forgive me im not so into the overclocking thing. So what are prime95 25.6 small FFTs load temp exactly?

 

[iluvgillgill]

download a software called Prime95 v25.6 and one of the function in there is called Small FFTs and it will load your processor at 100%(full load) and record the maximum temperature achieved. the MAX MAX safe temperature for the Q6600 is 70C!!!NO HIGHER!

 

[kayvon]

Ok so i set my fsb to 375 and put it on 1:1. My Results starting up were good. And my temps right now for my cpu is 40C. Is that good?
my memory frequency went up from 400 in Cpuz to 533. and i set my voltages to 1.47 vcore and memory at 2.1v. i did the prime95 and my multiple cores got up to 74C
and my Cpu got up to 64C. is that too high?

 

[iluvgillgill]

yes that is bad. you dont need that high vcore for that speed. can you post a screenshot of CPU-Z showing the 1st tab and the memory tab for me?

 

[Maziar]

You can test with OCCT too,its a good software and takes less time to test and it really heats up the CPU :d :
