q6600 3.0 overclock trouble

[kayvon]

There you go

 

[iluvgillgill]

alright go into the BIOS and select 1:1 memory multiplier and lower the Vcore to 1.37V. and load up prime small ffts for 15mins and make a screenshot showing all the above plus coretemp before shutting the program down.can you do that?

 

[kayvon]

yeah gimme a few minutes

 

[iluvgillgill]

maziar OCCT doesnt stress the CPU as much as prime95 do. and also when comes to stress memory no software stress more memory then prime95.

 

[iluvgillgill]

i want these showing in the screenshot.

instead of speedfan open another CPU-Z showing the memory tab ok?

 

[kayvon]

Sorry i forgot about the p95 program i did it before i read your reply.

 

[Maziar]

P95 stresses CPU more than OCCT? and how about "Orthos"?
Also for RAM,isn't memtest the best app to test?

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?

iluv, one question... why did you suggest 375 fsb? and a lower multiplier? if my guess is correct, a higher fsb and lower multiplier can sometimes be more stable than a lower FSB and higher multiplier right?

an additional note, dont' u think his timings are too aggressive? why not leave it 4-4-4-12? he's trying to not get BSODS, and you should only work on as few variables at once so you could target and figure out which variable is giving you BSODS. just wanted your thought thats all.

 

[iluvgillgill]

orthos is only 2 threaded so if stressing a quad core then you will need to open 2 copies of orthos and manually assign affinity to core 0,1 and core 3,4. in p95 you can easily put in how many MB of ram you want to test rather then other problem what size the FFT is. memtest i think is the best to test bad ram module.

blend test in P95 can stress all core and all the ram at the same time hence the whole system including the northbridge where data is transfering between the CPU and the Ram throught the FSB(NB).

the reason i ask him to pick lower multiplier so he can get higher FSB overall which will bring bigger performance gain in the memory subsystem.

his timing is ok i think be cause 4-4-4-10 with 2.1V and less then 800mhz if he did listen to what i ask him to do which will only bring him 750mhz. most ddr2-800 can do 4-4-4-12 with 2V so its logic sense that lower ram speed can just lower the timing further along with the increase voltage he chose. right?

just want you to know that mobo can sometimes have FSB hole where the system wouldnt boot at certain speed no matter what. that cant be fixed so the only way around it is to select a lower FSB or higher FSB. but you need to look after the capability of the CPU so you will have to select a lower system multiplier to get a higher working FSB to achieve the same CPU speed.

 

[iluvgillgill]

OP i think your cooler is not good enough to do 3.2Ghz i think you should just stick with 375x8=3Ghz. you will see much lower temperature with that slightly lower clock speed.

i stress myself again, 70C from the core is the max you should go.any higher you wont fry your CPU but it will cause a bigger damamge in a long term.did you decrease the vcore to 1.37V?

yar i was thinking of the FSB hole thing too...i wasn't sure about it in this case because it's a 3.0ghz OC and not something so extreme, but thanks for clarifying

 

[iluvgillgill]

but what my main purpose of telling him the lower multiplier is since his CPU is not capable of 3.2Ghz with that cooler. might as well try to get a higher FSB so the overall system and memory speed will be greater and that will offset some of the performance gap between 3Ghz and 3.2Ghz.

 

[kayvon]

what voltages should i put for 3ghz on 8x multiplier?

 

[iluvgillgill]

i would try 1.35v vcore 1st and small ffts for 12 hours if no fail then lower 1 more notch. what load temp you got now?

Ok,thanks for clearing it up

But for "Only" RAM test,its better to use Memtest right ?

 

[kayvon]

Okay ive done a little tweeking around of my own, and i set the multiplier to 8x and to 3.2 ghz and 800 mhz Memory speed. so 1:1 ratio. heres some images.

 

[iluvgillgill]

*ahem*where is the load temp?screenshot of CPU-Z means nothing if there is nothing showing its load temp. because stability and temperature is far more important then the actual speed. thats the reason why there is a thing call HSF/Cooler out there.

 

[kayvon]

turns out the last setup was unstable this morning so i changed the multiplier back to 9X and set to fsb to 1422 and the memory underclocked to 711
so far its stable under a few games, ill have a load test up in a few.

 

[iluvgillgill]

you better do!lol

 

[kayvon]

Had to underclock to 3.0ghz but it seems stable

 

[iluvgillgill]

so you cant get 375x8, ram 1:1 working at all?no matter how much vcore you give it?

 

[iluvgillgill]

and why is your screenshot so small?cant you make it at leave 1024x768? its really really hard to read it.

 

[kayvon]

the 8x was giving me a lot of problems, i tweaked the vcore around but i would either not start up or fail the stress test.

sorry bout the size

 

[iluvgillgill]

are you happy with 3Ghz. the 680i/650i chipset is well know to not OC well with Intel's quad core. and 3Ghz is about where most stop at. you can tryy increase everything further for a final push.

going to sleep now 99...zzzZZZ
