I was just wondering if anyone know what the limitations were for the P35 chipset when overclocking. The reason I ask is that I have 8GB of RAM and a Xeon Quad X3210 and the board (GA-P35-DS3P) will not run the memory at 1000 mHz (what the memory is rated at), but it would with a dual core. It will run Everest (CPU, FPU, Memory) stable for 15 hours at 400FSB, but when I try to burn DVD/CD, download, or extract, everything comes out corrupted. I was wondering if the chipset simply isn't able to handle being overclocked with that much "stuff" on it. It does run 100% stable at 333 FSB.
Yes I have, I have it running always at either 2.0 or 2.1. The SPD put the memory at 2.0-2.1V Trust me, I've tried every different configuration out there, except the suicide voltages, which I will try when I get home from work.
i have my P35 running on 425FSB with 1.65V on it.and its running a Q6600 so there are even more stress on the Mobo then running a dual core.so anything under 500FSB is achievable.but most people can achieve 450FSB with 7/8 multiplier.
I'm assuming by 1.65V you mean the MCH??? What is the typical stock voltage on it? Also, the problem I am facing is that I am getting 15 hours Everest (CPU, FPU, Memory) stable, but the minute I burn a CD, download, or archive/extract, I get crc/verification errors. I've tested to see if they are real errors, and yes, they are in fact actual errors.
You might want to try some of the other testing/stability programs in common use, such as memtest86+ to start with, and Orthos/Prime95. What model number RAM are you using, and what is its spec voltage?
yeah the 1.65V is the voltage for the NB/MCH.the stock voltage on the modo is about 1.25V if i remember correctly.
and i wanna aski why you use everest to stress your system?its never as stress as Prime95 does.i guess the reason why you used it is because you want to take a shortcut since it so called "stress" the "full system" at the same time where as cpu and ram need to stress one after another.
Actually, I heard that Everest tended to be a lot less lenient when it came to errors. Also, it is easier since I am too lazy to figure out how to run Prime95 on a 64 bit OS. Everest is natively quad core while Orthos is not (I believe Orthos runs the same that Prime95 does).
I think you miss understood me, I mean that Orthos runs the same calculations that Prime95 does, not the same as in how many cores it runs on. But anyways, how much memory do you have? I heard of one guy having a lot worse overclocks with 4x1gb vs 2x1gb. Being that I have 4x2gb, i wonder if i am pushing the limits of the chipset with the quad core.
Also, what board do you have that has such a good NB heatsink on it.
Also, I have had Orthos run for around 12 hours before. Two instances with the affinity set (if not it gets confused for so reason and keeps switching back and forth among the same two cores). I'll try Prime95 tonight, I found a simple .exe, much easier than the stuff I found on the actual site.
400x8 with 2.1v on ram sync with FSB with latency 4 NB+VTT/PLL@1.5V at least.remember higher ram ratio doesnt give you performance or speed gain.because the thing called MCH/FSB/NB in Intel's platform.its completely different to AMDs' so beware.
those setting i gave all have sucess and very good performance gain then 9x what ever FSB.but i jus give that to you as a baseline so you should look up from there.
