Now I've finally got my TRUE rev. C installed on my Athlon II X4 630 (Propus), I want to overclock it but I'm totally confused by all the guides on the Net that talk about reducing the NB, HT and RAM multipliers, as my BIOS doesn't seem to have those settings, despite being regarded as a good board generally for overclocking (Biostar TA790GXBE).
I can reduce the HT Link speed to 1600 Mhz (although CPU-Z shows it's running at 1840 Mhz) and increase the FSB but I can't figure out the rest. I've uploaded the pdf of the BIOS manual here
if anyone has the time to look at it (p.33 is where the manual overclocking section starts) to see if they can explain what I need to adjust.
This is what I've got/adjusted so far:
Spread Spectrum, CnQ, C1E - Disabled
CPU Vcore +0.5v
HT Link Speed 1.6 Ghz
Under Clock Control (at defaults):
PCIE Reference Clock 100 Mhz
SB Reference Clock 100 Mhz
Under Voltage (at defaults):
Memory Over Voltage 1.95v
Chipset Over Voltage 1.25v
HT Over Voltage 1.20v
DRAM Timings (had been running this Corsair Dominator @ 1066Mhz with these timings at the same voltage):
Auto Timings (5-5-5-15-22-4)
With those settings, I've been able to set the FSB to 230 to get 3.22Ghz @1.456v, the RAM runs at 460Mhz and it managed 5 passes of IntelBurnTest OK. CPU temp Min/Max was 24/40c.
Even though it passed IntelBurnTest OK, something didn't quite feel right and there seemed to be strange graphical glitches (I'm running a 6950 now, with the IGP disabled) that I hadn't experienced before, which is why I think I'm missing something important. I really want to get the FSB up to 250 for 3.5Ghz, but I did have a go at 250 and 240 but got BSOD on both. At least it's booting since I reduced the HT Link to 1.6Ghz, 'cos before I did that it wouldn't even POST and I had to keep resetting the CMOS with the jumper!
