Where to start with Isolating the CPU on this rig ?

post #1 of 6
Thread Starter 
I'm following the AMD OCing guide carefully, I've found the max reference clock for my MB - 237@10x HT and 10xCPU. At 240 it had an error running prime95.

I did modify some of the settings suggested for my gear, being a bit newer than the gear in the examples. Just the CPU multiplier (because it wouldn't post at 5x).

here are my notes from isolating the MB,

Ref Clock - 237
CPU x 10
HT x 10
CPU Voltage 1.3V (max allowed in my bios? a 2 week old version?)
Memory Timings 5,5,5,18,25,2T set @ 400Mhz (should that be @ 1066?)
Memory Voltage 2.1V
Northbridge Voltage 1.3V (also max allowed)but there is a NB-CPU Voltage setting, should I be using that? Should they be set the same?

Based on my gear what should I start at for testing the CPU?

Bring ur HT multi down to 8x. Now ur HT is 237*10=2370. But 9850 runs at HT 2000mhz.Then you can raise ur reference clock further. Ur 9850 has multi unlocked. If so try to raise the cpu multi and bring down the reference clock.
Remember if you raise reference clock then you have to bring different multis down to keep things running within limit.

One more thing. 9850 is a 125w processor. So ur Asus M3A-H/HDMI mobo is a bit weak to provide enough juice to the processor. OCing 9850 in this board could be hard due to this fact.

For some reason its usually getting around 150W. In what way is it a weak board? Just came out 3 months ago with AM2, AM2+ sockets only, pretty much designed for this chip isn't it? Something wrong with the 780g chipset?

Nobody else seems to have this MB maybe becaue it's not SLI.

Sweet, the 125W isn't actually the power consumption of the processor. That is the TDP (thermal design power) of the processor.

OpticWaves, you should have no problems providing power to the rest of your components.

Good luck

The motherboard is rated for 125w processors the new bios update will fix some problems that crop up after install with games hanging they were having a prob w/this mobo and 125w chips but the update fixed it for me just FYI
