Also, do you recommend the RAM x 1.5 rule for VRAM?

 

[MIAHALLEN]

each time you take a screen-shot...make sure to have two instances of CPU-Z open, one with the CPU tab showing, and the other with the memory tab

That error looks like CPU speed/voltage. is the bclock still at 205?

VRAM??? The iGPU uses system memory

 

[koala-czyk]

ok I am trying to get squard away.

A friend said its better to run lower multi's (8 to 10 x) and like 400 BCLK. What do you think?

I tried to do that but my RAM MHz was too high and I cannot find a divider anywhere. Do you have IM perhaps? I am meeting my friend on Myspace maybe you can help if you are not busy..

 

[koala-czyk]

I was thinking page file???

 

[MIAHALLEN]

I'm at work...so no IM

world record bclock stands at about 293MHz right now...you friend was probably talking about older systems that use FSB...but that's an entirely different subject

Did you try what this?

If you want to keep trying higher...then just run Prime95 for 5 minutes...if it doesn't have any errors, push the bclock up by 2MHz (with TurboV) and let it run for 5 more minutes...continue to do this until it does error (or lockup)...then report back

page file has nothing to do with OCing

 

[MIAHALLEN]

BTW - my OCing guide should be up in a day or two

Yeah I was just setting things up in Windows and I always remember to set page file to 1.5 RAM. I dunno why I brought that up..

I tried that and locked up then my friend was talking about different multi's and I got all screwed up.. Back to square one. I had to reset BIOS and start again.

 

[MIAHALLEN]

Yeah...don't rush it man...what you need to do is read my OCing guide Too bad it's not posted yet drop the CPU multi down to x16 and work on bclocks first...see how high you can get the bclock, then go back and try to bring up the CPU

 

[koala-czyk]

Is there a RAM divider in BIOS? Friend wants me to run 8x and higher BCLK and need RAM divider. I told him it is different that CPUs with FSB. Not sure what else to tell him.

 

[koala-czyk]

What are your settings?

 

[MIAHALLEN]

I was cooling with liquid nitrogen...so my settings were much different than yours. This is not my every-day system...I was only running it for HWBot points.

 

[MIAHALLEN]

you can see my settings here:

Wow you are FLYIN! Awesome job, and thank you for all of your help. I am at 210 x 19 slowly inching. My RAM is my downfall I think.. I will keep inching up the best I can. Thanks Matt, also for all of your help.

Maybe I will do some folding

 

[MIAHALLEN]

Hey man...my overclocking guide is now up:
http://www.overclockers.com/3-step-guide-overclock-core-i3-i5-i7/

 

[x509]

Great Guide. Awesome doc. This will be my "go to" for overclocking.

I vote for STICKY here.
