Changing RAM Voltage

[Medi0120]

I accidentally purchased 2x8GB RAM sticks that operate at 1.5V, rather than the recommended analogous sticks that operate at 1.35V. I thought I would try to change my RAM Voltage settings in my BIOS before taking them back to the store. Does anyone know what kind of problems I might run into by increasing my RAM Voltage?

Additional Information:
PC System: Asus M52BC US005S
MOBO Model: M5A97 EVO R2.0
BIOS Version/Date: American Megatrends Inc. 0203 08/07/2014
RAM Part: Crucial Ballistix BLS2KIT8G3D1609DS1S00

When they are installed what voltage are the running @ stock?

The M5A97 EVO R2.0 uses 1.5 sticks (can also run up through 1.65), which is what you bought, the Crucial are 1600/9 1.5, not sure where the 1.35 came from, unless Asus put low voltage in there originally, you don't want to mix DRAM anyway

I contacted Crucial and spoke to tech support, because their website "guarantees" compatibility between the cards I bought and my computer. After I discovered they were, in fact, incompatible, the Crucial representative referred me to the 1.35V cards, and once again "guaranteed" that they would be compatible.

My computer won't boot at all when I try installing the new cards.

Just one of the reasons I don't use crucial, if you look through the mobos QVL, for DRAM, you will find basically all the DRAM on it is 1.5-1.65 (saw 2 at 1.35)

I'm positive the sticks I bought are 1.5V, and that my computer won't boot when I try to use them. The Crucial rep said I had the wrong voltage, but if you are suggesting otherwise, any idea what the issue might be?

Can you try them in another rig, or have other known good DRAM you can try in this? Could be lots of things, if other DRAM won't work either I'd bench it, have a guide here that might help:

I took my PC to a certified ASUS Technician and they assured me my CPU/GPU/MOBO are all connected and functioning properly, as is my existing RAM. I've also determined that my existing RAM is running at 1.5V.

It seems that Crucial's RAM is simply incompatible with my MOBO, despite what their website guarantees. I'll have to check out some RAM from that QVL you shared.

I'd look to the GSkill Ripjaws X or Sniper lines, they are compatible and work rather well
