Can't pass blend, is it RAM or NB?

post #1 of 7
Thread Starter 
Hey guys currently on a PII 955 at 3.9GHz 1.425v, as far as I know the CPU overclock is stable with 10hrs+ of small FFTs.

After that I tried to mess with my memory which is the ocz3p1600lvam2g 2x2gb kit and it has run fine at 1333mhz for a while now with 6-6-5-20 timings on my PII 720 but I wanted to get it to run 1600mhz which I automatically seem to fail blend test on regardless of any voltages or NB settings (even at stock). Is it just not doable for me to run 1600? I can't even run the rated settings at 1600mhz. But I pass memtest at these settings.

Furthermore, after putting in my 955 from the 720, I tried running the same NB and memory settings which was 2600mhz NB and 6-6-5-20 timings at 1333 mhz on ram with same voltage settings (1.65 DRAM voltage, 1.35 CPU/NB) and I don't seem to pass blend for 3+ hrs on those settings. What's going on here? is the NB messing it up?

Any help or any OC tips would be greatly appreciated. Thanks.

run stock timings and test.
lower speed for RAM and test.
Put a fan on the NB cooler and test.
Increase vcore, NB ect and test.
Lower overclock til you get stable.

The NB chip has nothing to do with oc AMD. NB chip only control the PCI-E slots.

He most likely meant the CPU-NB, which is the memory controller.

Don't try OC'ing both the CPU/NB and the RAM at the same time, you'll go nowhere. First things off, I suggest getting the CPU/NB stable first before the RAM. That way you'll know that you have a stable connection between the Integrated Memory Controller and the RAM.

The goal with Phenom II's is to overclock your CPU/NB Frequency to about 2400MHz-3000MHz, the higher the better. I recommend around 2600MHz, which you can start with 1.3500v of CPU/NB voltage. Continue testing with Prime 95 blend and try your best to find your stable setting.

After you've found a stable CPU/NB Frequency, try for the RAM. The reason why it's going to be difficult running at 1600MHz is because you are running on a divider if you are overclocking your CPU by the FSB. I'd keep the memory frequency where it's at and try to tighten the timings, that's the way to go with AMD

Hopefully, this helped you out a little bit.

The reason why it might be difficult running 1600Mhz is your C2 revision CPU
You might need a bump in the DRAM voltage, usually it helps

Look at the first quote. Fan on the NB cooler. That is why I'd said it.
