AMD Phenom II 965 BE Overclocking issue

post #1 of 8
Thread Starter 
I'm pretty new to OC but have done my fair share of reading. I'm having issues OC my cpu to over 3.8ghz, I've gotten my cpu at 3.8 stable on a 2 hour Prime95 test but when adjusting either the multipliers or core V to 3.9 I get BSOD after 5 min in to logging in and starting up Prime95.

My last test run was set at:
Core voltage at 1.46
Bus speed = 205.8
HT Link Speed = 2058
Multipliers = 19

Temps:
min = 29c
Max = 42c

I've tried playing around with some combinations (Multipliers, Core Voltage, Bus Speed, CPU/NB, HT Link) and found this to be the most stable. I've also tried pushing down my DRAM but made no difference in stability.

I'm running an Antec Kuhler 620 with two CM Excalibur fans as push/pull

Any suggestions? comments? Thanks!

Have you tried 19,5x multi at 1.5v?

For 4ghz try 1.4750 v.

Currently, I have:

FSB at 250
Multiplier: x16.0
CPU Voltage: 1.4750
Northbridge: 3000
CPU & Northbridge Voltage: 1.5000 (still in testing, this is being brought down gradually over Prime tests)
VDDA: minimum (2.50 I think).
HT Link 2000
HT Width: 16
HT Voltage: minimum (1.20 I think)

Temperatures: 45 degrees.

Some of this may vary between boards so check your minimums in the BIOS.

The 965BE is good upto 1.55 volts if I remember rightly. Also you have to take into account voltage drop. Don't be scared to pump 1.5 into it purely for testing, you can always bring it back down gradually.

If you have CPU-Z and Core Temp, take a screen of that while at full load in Prime and post it up.

I'm surprised that you are having to push your voltage for 3.9 GHz. If you are blue screening, it could be a memory issue. What voltage do you have going to the memory? Also, what speed is it running at? The FSB being set above 200 could push the memory a little to far. I know it's a stretch, but the blue screening is likely the memory.

HT Link Speed won't make much of a difference and when I pushed mine above 2000, I experienced issues.

So after a few hours of testing I could only get the core speed to 3.85...anything more and my pc BSOD. Thinking it might be the ram clocking to hight I went and really pushed down the ram to 800mhz but still no luck.

Here is a screenshot of my current progress. Prime95 has been running for over an hour now so i would say its pretty stable

I would try a lower multi and higher reference clock.
You can get smaller increases in cpu frequency using the ref clock.

I just noticed that your CPU has C2 stepping. This is likely why you are capping out at 3.85. C3 processors are much easier to overclock. Maybe another guy with C2 stepping will have better advice for you. I have never OCed a C2 chip. Good luck!

^ That's what worked for me. It does mean that you need to go back quite a few steps to start stability testing. Try getting stable with a 250 reference clock and a 13.5 multi. Get the volts as low as you can and then start bumping up the multi. Good Luck!
