After I checked your ram specs, I see that it requires 1.8v with +/- .1v, but it doesn't really give a top end for voltage.... so to be safe, you should run it at 1.9 or maybe even at 1.95. That test you linked could be trustworthy.... it sure seems possible for the ram to run those timings at that voltage (doesn't matter if it's AMD or Intel).

Memtest is a self-booting program you have loaded onto a floppy(or burned to a CD). As you boot or reboot your pc, (with the disc in the drive) it will start before your OS loads and run tests on your ram. You can let it run as long as you want, or stop it at any time.

On two different chip set MBs, it seems the SB gets a bit voltage hungry, even when the RAM is stable it can error out.
You would think DDR2 800 at par or even slightly below would be fine even sit the various sub timing tweaks and proven stable.
But, as the OC got near the high end RAM errors! All it took was a SB vbump to cure it even though the RAM was still in about the 780-820 range.
BTW. AM2/AM2+ seem to be very friendly to OCing to higher HT speeds up to the mid 1300ish range.

Thanks, Duke.... that's good advice to follow.... I know I've been following it. When I've been working on raising the OC on my 770, it definitely helps stability when I add a little more bridge voltage.

wow so much misinformation!

use 2 instances of orthos

Instance One - run Small FFT's - This will stress your CPU much more than ANY other test

Instance Two - run Lage FFT's


You may also want to up your ram voltage.

Hey Winger...

This bloke here:

http://www.hardware.info/en-US/produ...B_DDR2800_kit/

Apparently overclocked the same RAM as me at 5-5-5-15 @ 2.0V
now i know my stock ram is @ 1.8V, but i set it to 5-5-5-15 @ 2V since it was crashing on that timing when i ran it @ 1.9V.

Do you think thats too high?

I ran OCCT RAM & CPU for the 30min block...ran all the way. shuld i notch i tto 1.95V or leave it?

You can try it at 1.95 to see if it will run stable there.... it doesn't hurt to see if you can get by with less voltage. The ram specs are a little vague as far as the max voltage you can run, but you should be okay yet at the 2.0 (most DDR2 can handle that for voltage).... otherwise, it might be worth it to check with Kingston tech support to find out for sure.

Also, as the Duke mentioned.... a bump in SB voltage can help with stability.
