So I recently fried my gigabyte ga-990xa-ud3 and I bought a cheap $60 biostar while I wait for my refund (was only used for 24 days). Upon refund I want to order a nicer board with the 990FX, anyway back to the topic. I have a FX-6100 and a Phenom II X4 980 and I popped the phenom in my biostar board yesterday and I got the two CPUs confused because when the BIOS autoset the voltage to 1.40 I thought it was really high because my FX-6100 stock voltage is 1.225. So I set it down to 1.225 and it didn't work but I got it working at 1.275. It wasn't until a few hours I realized that the stock voltage for the Phenom is 1.375-1.40 and I had gotten the two confused. Then I was suprised that I had run Prime95 for 2 hours with no problems (I ran prime to see my temps because I was using the stock cooler. I didn't want to bother with installing my Zalman CNPS9900MAX because I'm getting a better board for my main computer soon and this Biostar is going to be my backup rig or for one of my kids.) Anyway I guess what I'm asking is how low have you gotten your phenoms or how low have you seen? I've seen pretty low but 1.275 is sweet especially because my stock cooler keeps it under 55C after 2 hours of prime95.
Also, I think I've taken a liking to this Biostar board. Its the A880GZ i got it for $60 on newegg and aside from it being an older board I haven't had any problems, the BIOS was a little different but I figured it out. I want to get either the ASUS Sabertooth 990FX or the ASRock Fatal1ty Pro 990FX, anyone have any experience on these? I want to get a 990FX board and I'm still hoping either AMD or Microsoft has a fix for my bulldozer chip in the near future. Plus I want to crossfire my 6870 soon and this biostar microATX doesn't have the ability. What do you think?
I've gotten mine to 1.275, which is the minimum @ stock, though I have the 965.
For some reason, my Gigabyte GA-990FXA-UD3 rev 1.1 auto sets the voltage to 1.475, same as your Biostar. I guess is so you can OC'd without havin' to hamper with voltages, since, by just increasing the multiplier I manage to get my 965 to 4.2 GHZ.
