Here we go, now the machine is up and running, so begins the quest to find out what it can do!
Well, last night I tried what I thought would be a relatively straightforward overclock, not expecting any problems, but I've had no luck with it.
I was trying to get the PC to work at 3Ghz/400
fsb/1600 memory. So just a
FSB overclock, with the memory running with it. Most of the time I could get into windows, but occasionally it would hang during
post. When I ran prime95, it would invariably blue screen or lockup and reset the machine within 30 seconds or so of running. This was all tried with CPU
VID set at several settings, up to 1.35, and I tried
NB voltages of stock through to 1.4. As well as voltages, I tried all the different Skew models for memory, 0-4 on the 06/09
bios, and 0-7 on the beta
bios. 2 and 6 on the beta
bios gave the "best" results, though this only meant rounding errors in prime95 rather than bsods or resets. Bear in mind I only tried each skew model once, so 2 and 6 may well bsod next time. It was late, and I was just doing some quick tests before bed :P
I also tried different straps to keep the memory at 1600, but this didn't seem to have an effect.
After trying this, I thought I'd try and see what each part would do individually (as far as I could), so I kept the
fsb and memory at 333/1333, and used the multiplier to clock the CPU. This gave me some hope, as the cpu clocked up nicely, with a little voltage needed as I went upwards. I was able to do 3.2 @ 1.25v, 3.4 @ 1.3, 3.6 @ 1.35, 4Ghz seemed nearly stable at 1.365, though I didn't push it any more at this point, I'm sure it would be ok at around 1.4v. This was just to see if the cpu would clock independently of the
fsb/memory, and the voltages could well be lowered with some fine tuning.
So I went back to the
fsb/mem, and tried keeping the memory at 1333, 9-9-9-24, but the bsods and resets continued.
Any ideas guys? I'm at work at the moment, so I won't be able to try any suggestions till later on.
1st e: oh, and temps aren't really a problem: cpu idles at ~25c, load at ~35c @ 3Ghz, up to ~40c @ 3.6Ghz,
NB/
PWM ~42c pretty much all the time.
2nd e: My
PSU does make strange noises while under load (not much load though, wattage wise it pulls a max of 330W when cpu and gpu are going, ~270 with just the cpu being stressed, 170W at idle). These consist of high pitched whines, scritches and odd noises which are directly related to what is going on in the PC... When ATITool is doing it's artifact scanning, the noise is distinctive. When prime95 is testing, the noise is there, and will change frequency/amplitude exactly when the tests complete and the next test in the procedure starts. The sound was there on the old motherboard as well, I just realised it was still there with the T3RS last night.
