965BE and 990FX Mobo BIOS question

post #1 of 10
Thread Starter 
Hey folks,

So I'm adjusting my Overclock. Trying to reduce heat, but keep my 4.0Ghz.

I was looking over my settings and noticed my CPU voltage was upwards of 1.45-1.49v. Now, that's far to much and the extra heat generation is very noticable.

So I went into BIOS and set it for 1.38v to see what I could get.

However soon as I start prime it increases the volts to 1.41v which I'm getting back into the situation of adding extra heat when I can more then likely get stable at 1.39.

I was wondering in this new BIOS from Asus which setting is the one that adjusts the extra volts the CPU will get. And what setting will keep a stable amount of volts?

I don't want it to increase on it's own. If I want 1.38 I want it to sit at 1.38 with minor shifts. But not a noticable change like I'm getting.

Under the "AI Tweaker" DIGI+VRM section disable the CPU and NB/ Current Capabilities, and set LLC to disabled, that should keep the VRM from adding power to maintain stability. You might beable to leave LLC enabled, just play with the settings and see what works for you.

Thanks, I'll give it a swirl. I had to play BF3 with my community so I swap to a safe 3.8ghz profile and left my 4.0ghz profile to tweak when I get back off work. I'll try this! Thanks a ton!

Yes the Digi+ VRM has a lot to do with this. The load line calibration affects this.

Take a look at this. This might help you.

Yea, as I was digging through, their is no option to disable. So I'm still getting overshooting volts. It held at 1.37v fine, but then suddenly it shot upto 1.4v and bam heats rapidly increased from 54c to 60c rather fast.

So still trying to find a method to stop this increased volts.

So I adjusted LLC and CPU/NB cal to 110% and now instead of having a over volt issue. I'm having a undervolt issue. And I cannot figure out which one hit it..haha

Gonna change out my TP tomorrow. I tried some local brand but I have some TX-2 with 4.5W/mk thermal conduct. So much better then what I'm using. Should reduce temps a lil more..haha

Never dealt with such a pain in the ass BIOS. I cannot keep this friggin voltage stable. And that's pissing me off. I've done everything I can thing of with LLC, NB/CPU Cal, power phase. I just cannot figure out how the heck to get this table. I got 1.37v set, however the best I can get is 1.35v or the complete other direction and get 1.39-1.40v I cannot get it on 1.37 like I want..

Try to set the voltage to 1.34-1.35 and see if it goes to 1.37v like you want. Do not use over current protection. That causes problems for voltages especially when overclocking.

I dont think that any voltage will be "set" for cpu seeing that it has to adjust to its needs. It will fluctuate slightly regardless.

That's a good idea, and I tried it. However it's still jumping over my set limits for volts. I've never had a BIOS or chip just do it's own damn thing after I've set the limits. Kinda annoying.
