Trouble getting 3.8Ghz stable with 955BE + m4a89gtd-pro/usb3

Well if the chip has a low vid its possible.

Honestly the diff between 3.7 and 4.0 is marginal at best in the whole scheme of things. Also if it helps my 940BE didnt like ANYthing above 55c. Keeping it under that REALLY helped higher clocks.

Ive had some success getting to 3.9~4.0 by bumping CPU VDDA up .1v also. This was a dealbreaker at 2700+nb to go figure.

Your system has alot more performance to tap into then raw cpu speed. For example try getting to a stable 3.7ish clock and start pushing the NB and Ram frequency's.

If you have a decent chip you will hit 2750+ NB. Do NOT use anymore then 1.35v to get there on air.

Set rams to rated speed while cpu/nb is in a known working lower end range and just use AOD in windows to bump FSB until ram flakes. Then apply .05v or so and do it again. Any 1.5v rams can handle 1.65v easy but i personally like 1.55v max on mine.

The key here is to clock each item separately untill you have an idea of what they top out at.

If im repeating what has been shared already i apologize

Much appreciated Jethro, although for some reason my CPU overdrive is disabled and it wont let me slide to unlock it, wants me to first run auto-tune, which I am sort of nervous to do. :/

[Jethro]

Did you switch it to advanced mode? I use the stand alone AOD not the built in catalyst one. The beauty of clocking within windows is not waiting on boots, you can instantly test and often remain in windows even if it fails and of course no corrupted boot sectors

The Asus Turbo V software works great you might try it. In fact im using the Asrock version now and really like it.

[Bri7man]

Yeah I have advanced view enabled in prefs, although still wont let, I'll check out Turbo V though

[BeepBeep2]

I know for a fact that TurboV works

[Bri7man]

TurboV EVO is pretty cool

I'm using your parameters Dave and it's stable :P Although 1.475V puts my actual voltage at a steady 1.50V and I'm hitting 58C at times while folding, so it looks like I'll have to lower that and the bus freq if needed.

Question- An increase in DRAM voltage would have no effect on the CPU temp, right? Although HT voltage and NB voltage most definitely will?

Uhh, only CPU vcore (CPU Voltage) and CPU/NB voltage will have an effect on the CPU temperature under load. The others are for different parts/busses.

Ahh okay, makes sense. I worded that terribly too ><
