Help please - Overclocking e6850 on 680i Asus Striker Extreme

post #1 of 4
Thread Starter 
I upgraded my ram finally so I'd like to try overclocking my cpu up to squeeze some performance out of this machine while I save up for an x58 build. So far I've had no luck. I would like to achieve 4ghz on this cpu on air. Keeping under 60c is more important to me though so if I can't do that on air I will aim for a lower clock.

What i've tried so far to get even a boot @ 3.6ghz was raising fsb to 1600 w/ the stock 9 multi for 3.6ghz. No luck. I tried all the way up to 1.35 vcore and still nothing. Some people have told me to lower my multi to try and get higher fsb to keep 1:1 with my ram but that doesn't even really make sense to me, my ram is only 800mhz ddr2 so wouldn't a 400x9 be 1:1 while putting me @ 3.6?

Anyways i'm pretty lost from here. I had to drop back to stock to pass the bios post and get to this point so I could post this here.

have you tried a lower overclock? Sound like it might be a FSB wall or you need more NB voltage.

Yes I have. But if I go lower than 3.6, I might as well just stay stock imo. I'm just trying to use 3.6 as a starting point for the goal of 4.0.

Okay so I finally got it to boot at 3.6 and not crash in 30 seconds.

But I have even more questions now.... When I left it on automatic voltage it would mostly boot into windows but crash after about 2-3 minutes. It seems to be fine so far though and I'll stability test here in a bit. But somethings bugging me, in BIOS I put my cpu voltage all the way up to 1.45v but in CPU-Z it shows as only being 1.344v. Why is this? Is my board purposely using lower voltages than I told it to or is CPU-Z not showing the correct number?

Also. I left my ram unlinked because if I leave it as linked it goes up to like 1034mhz and my board is only rated for up to 800mhz ram. Is this bad? Will leaving my ram stock but upping the cpu fsb hurt my performance gains at all?
