AMD FX-8150 on a 990FX-GD80V2

post #1 of 4

Hi all.

So I've had this set up for a while but I got stuck OC'ing it and gave up, now I'm back at it but I'm stuck in the same exact place I got stuck last time. I seem to be limited to the voltage I can put to the CPU. Before I get into it more, Here's the set-up

MSi 990FXA-GD80V2
AMD FX-8150 w/ AMD Watercooler
G.Skill Ares 16gb 1600 MHz
EVGA 660 Ti
Samsung Spinpoint 1tb
OCZ Agility 3 60gb SSD
Thermaltake TR2 600 Watt Powersupply.

Basically this thing is half new, half from my old budget build (As you can tell I'm sure), I've set up two different OC's for it, one is a 4.6GHz Quad core, the other is a 4.1 GHz Octo core(Pending passing current stress tests). My problem is that my motherboard seems to limit me to only 1.44v. The quad core clock is stable at 1.425 while the octo core clock is at 1.440 (Multipliers only). The water cooling is only running at half speed and keeping the CPU at 50 degrees, so I know I can definitely push further, but I just can't bring the VCore any higher. I was thinking that this may be due to my weak powersupply. I was wondering if this was possible? Could the mobo be limiting my VCore based on what the powersupply can provide?

I doubt it, even though that is not a quality PSU.

To answer the question just hook a volt meter to a spare 12v molex and see how low it goes.

If you still have the installation cd you will find 2 utilities on it that let you overclock and set up the bios from within windoze.

One is called Control Center and the other is called Click Bios II. Some prefer to use CC and I prefer to use CBII.

I have taken my vcore as high as 1.65V but one could go much higher. Here are my settings for a 4.6ghz 8350.

hmmm. I'm going to check into Click Bios. I've only used the actual Bios and Command Center. Both limit me to 1.44v.
