I am experiencing some graphics lockups with my new Tyan Tachyon G9800Pro. I installed the Tachyon Graphics Monitor and found that the Memory Core Voltage is "Low". It sets at around 2.65-2.68v. The safe range for the card is listed as 2.7-3.1v (and i have seen images in reviews that put the normal at around 2.9v).

Is there any way to get this up to the safe range?

System is:
Chaintech ZNF3-150 Motherboard
420W Enermax Noisetaker Power Supply
Athlon 64 3200+ CPU
Tyan Tachyon G9800Pro-M

I want to avoid an RMA on the card (such a pain in the butt to do that).

Thank you,

Sounds like your power supply is not up to the task. It either has a low rail or too many things on that rail. You do have the molex connecter plugged into the card right?

Yes i have the power supply pluged into the Video card.

Every other voltage level on every other device (that i can measure) is fine. Just this memory core voltage is low (all of the other voltages on the card are fine)

I will try another connector into the card.. I hope the PS is not the problem, i bought a high quality PS to avoid these type of problems.

My ATI-branded card also had memory voltage around 2.7v. I used a voltmod to bring it up to 2.8v and was able to increase my memory clock from 378 to 385. I moved it up again to 2.9v, which is the stock specification, and was able to run the memory at 389. (22MHz DDR isn't bad for just increasing the memory voltage to stock levels, though it does seem that the memory is near its limits).
