severe voltage fluctuation with 990FXA-UD7

[mxthunder]

Recently purchased a 990FXA-UD7 motherboard for use with my 1090T.

When under load, the voltage fluctuates so badly that even at a mild OC, the CPU is unstable. Setting 1.55 in BIOS becomes as low as 1.408 under load. The voltage never stops fluctuating the whole time. Is there a newer BIOS I can flash to to fix this error? I am running BIOS F4b


Thanks,

Hi

I don't know if your was one of the ones updated but a lot of new updates were released today.

[mxthunder]

Can you explain? what kind of updates? The newest BIOS I see listed on the site is F4B

[Dark Mantis]

In that case maybe there wasn't any updates for your board. Have you checked on TweakTown Forums ?

I am also seeing pretty huge voltage fluctuation. Not best happy when the board cost over £200 ($320) and my CPU's not stable at stock/auto settings because the voltage being supplied to the CPU is miles away from what its meant to be.

I've tried GGTS before (2009) and simply never got a reply. I've sent another ticket to see if it helps any but I have my doubts.

No updates for the 990FXA-UD7, the very top AMD board Gigabyte makes, craziness. And to think, I thought I was paying the extra NOT to have problems.

[mxthunder]

Yeah, I am starting to wish that I had gone with the MSI GD80..

Hi

Don't forget this is a new platform altogether and so you have to expect teething problems. I am sure that they will be ironed out as new BIOS updates etc come along as everyone is learning as they go. Part of the joys of being on the bleeding edge.

Release incorrectly functioning products, hope to fix them later? Gigabytes been open since 1986. Making motherboards with the latest chipsets is nothing new for them. As stated in many reviews, there isn't even a large step being taken in the chipset design.

[Dark Mantis]

No I know what you are saying but this time it was a step up from the P67 chipset and that wasn't out for long itself to have all the bugs ironed out of it before the Z68 was released. Normally there is a significant time between releases.

[mxthunder]

ummm we are talking about 990FX chipset here, not Intel stuff....

@ mxthunder

What do you mean by saying "CPU is unstable"?
Do you have any BSODs, hangs, restarts?

[mxthunder]

BSOD's and hangs. While gaming, and stress testing.
