MA785GMT-UD2H - why's my RAM at 1.6v, & can I fix it ??

[expatCanuck]

Greetings -

I own an MA785GMT-UD2H board.

I recently upgraded my CPU to a Phenom II X6 1090T,
installed the v9 BIOS, and added two sticks of 4GB RAM --
Corsair CML8GX3M2A1600C9.

By default, the RAM ran at 1333, so I increased the multiplier from 6 to 8,
after which the RAM ran at the spec'd 1600.

However, for reasons that elude me, board is powering the RAM at 1.6v,
as opposed to the spec'd 1.5v.

The BIOS appear to allow one only to increase the DRAM voltage.

Is there a way to lower the DRAM voltage to 1.5v?

Insight welcome.

Thanks,

 - Richard

P.S. -  If it helps, here are two images -- one with the PC at idle,
and one under load (with turbo kicked in -- 18 multiplier).

Same board mine is a revision 1.0..using the last bios F10B 1.6v seems to be the lowest setting.

My cpu is a 1055t 1 thing I noticed is your core voltage is very nice,even under load compared to mine.
I got a blue screen while Folding this summer and noticed that left to defaults the board was feeding it 1.527 or some such nonsense
had to go in and manually reduce it.

What revision is your board?

I'm currently undervolting the CPU by a modest .15 volts. 
(Haven't yet pushed the envelope to see how low it can go.)

Slightly (.05v ?) undervolting the northbridge as well, I think.

Less is more.   

My board is rev. 1.1, with the F9 BIOS.

Hi Richard,

I'm pretty certain that the RAM voltage setting of 1.6V has been done by design as Gigabyte found that lower voltages caused instability and it cannot be lowered. Whilst this is annoying and frustrating Gigabyte have stated that it won't damage the RAM.
