Motherboard will not boot with mixed set of DDR2 Ballistix, need to verify voltages

[brinstar117]

Hello, I have a GIGABYTE GA-P35-DS3R and two different pairs of Ballistix.



My first pair are BL12864AA804.16FD3. They do not have any labels indicated voltage spec.



My second new pair are BL12864AA80A.8FE5. They have labels that indicate they are 2.0V.



I don't think my motherboard can individually set voltages on specific memory slots. If my old RAM requires a higher voltage, is it safe for me to boost the voltage of my newer sticks? I am not concerned about overclocking or having aggressive timings on the RAM, I only want a stable system. Thanks!

Every reference I found says they are spec'd at 2.2 volts. Those modules also had a pretty high failure rate, it seems.

Re: Ballistix Voltage Problem.Options

"As a general rule we do not recommend mixing modules that are rated for different voltages, particularly not if you are manually setting voltages and timings in your BIOS. I would not recommend running your new 2.0V parts at 2.2V, as that will void your warranty. Instead I suggest that you contact our Customer Service to discuss your options."
