Overclock This!

[Adn4n]

Ok, my specs are in my sig.

I overclocked to 2.3Ghz(10x230) at 1:1 2.5v. Now that is the lowest setting for ram, but it worked just fine. I passed all the tests. So now that I figured my ram was stable, I booted up and ran Prime 95. Prior to memtest, I ran Prime 95 at 1.55v and was stable only for 30 minutes and 40 on 1.575. I ran Prime95 right after the memtest, and failed after 1 second on both 1.55 and 1.575v with HTTx3.

Why did I fail so quickly, was it because my ram was tested so ardently? Does it have to cool down?

I upped ram voltage to 2.7, the max, and no luck. Then I increased the cpu voltage gradually to 1.65, but no luck either. I am going to try 9x250 at least, not quite what I was looking for, but it'll do. Also, I failed the 10% overclock at 10X220 HTTx4. I tried all possible voltage combinations, but I still failed Prime95.

Also, which specific test do I have to run? I always ran the torture test that tested a lot of ram.

Oh yeah, the Clawhammer is CG stepping, so my memory controller is not at fault.

I think that if your system (ie ram) can run @ 9x250, you'll get even better performance than 2.3 GHz at 10x230. What's your power supply?

 

[Adn4n]

450 Antec.

Could anyone post a link for clockgen? I can't find a working one.

Ok, 9x250 won't post on a 400Mhz divider. At 333 it does, but I isn't this going to slow down my overall performance?

Edit: 9X250 at 333 failed after less than a minute in Prime95.
333divider:
1.55v-1.625v less than 1 minutes before failing Prime95
1.65v 1.1 minutes before crash.
I'll try a lower divider now.

change ur ram to 166mhz
change ur fsb to 250
change your cpu multi to 9
put ur vdimm at 2.7 or 2.8
change ur htt multiplier to 3

EDIT: if your mobo supports it up the chipset voltage to 1.7

 

[Adn4n]

I've tried that already, didn't work either. Tried every divider with every possible voltage combo. I think it is time for some RMAing.

 

[BW86]

what are ur temps?

 

[Adn4n]

32C idle, 42C during prime, 52C max

 

[Adn4n]

166 divider gave me worst results so far, and going down to 100 would be the worst. That is, 333 and 200 in ddr terms respectively.

 

[BW86]

errr than something is wrong

i guess u got a chip that cant oc that well

Yes, I found the problem. The Antec PSU was a piece of crap. I exchanged it with the cheapo that came with my case and now it's stable at 250x9 2.7v ram and stock cpu voltage.

Hard to believe but I suppose anything is possible...screenshots perhaps?

Still failed Prime after 4 hours, but a major improvement. I'm sure I can get better results with increased cpu voltage. As for the Antec, it was used in an XP system before I got it, so I'll be getting a new one soon. Any recomendations? Would a 350 do justice?
