Hmmm.... northbridge.....hmmm.... didn't occur to me that the NB could be holding me back....
I guess I should try some other stuff before i give up on the 4 cores....
Nice going btw!

Kurt1288, just remember not two processors are created equal. You could just be the unfortunate one that has a poor overclocking Ph II. Have you included any CPU-Z screen shots of your overclock for us yet? Perhaps something else is holding you back?

Let us know

Good luck

Ya, back on page 54 I included some CPU-Z screens. Currently though, I don't think that (what is shown in those screens) is stable as my system crashed this morning while on the internet (no real load). I changed my ram timings (from BIOS default to what the ram said it was) which is the only thing that I can think of that introduced the instability, since before that change I ran Prime for 7 hours (with the same multiplier and voltage settings). I'm now running Prime with the same Vcore and ram settings (as shown in those screens), plus an increase in the NB VID voltage of +.05 (if I remember correctly).

I definitely understand that I could have gotten a CPU that is less inclined to be overclocked.

Kurt1288, just to clarify so you are currently testing 3.7Ghz at 1.475volts? What is your memory frequency currently at?

Good luck buddy

Yes, that's correct. Memory Frequency is 201 (stock). Prime got an error so I'm gonna have to try again .

What's the benefit of ram at 8-8-8-21 vs 9-9-9-24?

Here is what I am testing now thlnk3r...



My chip seems to love undervolting so I thought I would push it a little more. I did boot into Windows w/ -.075 @ 3.6, but CPU-z showed my multiplier @ 15.5 @ 3.2...so a good indication that it wasn't stable, so I didn't even try and bench tests.

If all is well at these clocks, I will try and push the FSB a little more, and then work on tighter timings for the ram hehe

Still idling under 30c for a 3.6 OC and a 2400 NB

8-8-8-21 yields better performance than the other one.

guys i think im at a wall with 3.8ghz
i managed to get 3.81ghz stable with 2530mhz NB 1.44v and 230 fsb.
i cant manage to get 3.9 to last 30 seconds in p95.
at 1.44 i load at 49C cpu temp (i dont know my core temps).
i have tried everything to get 3.9ghz. i have used varied volts from 1.44 to 1.52
i have tried diff NB's but no luck. my ram is at 920mhz with 5-5-5-15 timings. i tried to loosin them up from 1066 to help but it didnt help much. i have tried 800mhz ram with 6-6-6-18 timings to try really loose but i still cant get it.
i have a screeny below with my current CPU-Z
i dont think there is much else i can do. btw, at 1.5v i load at 53C cpu temp.
thnz for any input
