RAM Voltage Question

[purple stain]

I currently have 4G(2Gx2) of DDR3 2000mhz timings are 9-10-9-27/1.65v.Currently running it in SPD mode at 1333mhz with timings of 9-9-9-24/1.5v because of my mobo.

The RAM I have is 2000mhz but with a voltage of of 1.65 at that speed.I've been looking around for some new 990FX mobo's and all of them have 1.5volt RAM slots.Can i run my RAM at 1.65 volts even though the mobo says it's RAM slots run at 1.5 volts? I haven't come across any mobo's that run at 1.6volts or above.

You can but not recommended. Keep the 1.5V/1333 and try to tighten the latencies further but the current settings are OK.

Well why even make RAM 1.65v if no motherboards support it?

 

[Leaps-from-Shadows]

IIRC, AMD CPUs can run 1.65v RAM just fine. It's Intel that doesn't recommend it.

And they still make the higher-voltage DDR3 because previous generations of boards still support it.

O I see.How does the RAM voltage have any affect on the CPU?

 

[Leaps-from-Shadows]

Because the memory controller is built into the CPU, it can be fried if the RAM voltage is too high.

Alright.

Thankyou so much.
