I5-3570k with 1.65v RAM?

I recently bought components for my new computer, however, I was not careful when I bought my RAM (), and the RAM is rated 1.55-1.75v. Usually 1.65v is required to run them at 1600MHz... and I kind of want to get what I'm paying for.

I was wondering whether they would be incompatible with the CPU as I know Ivy Bridge CPU's use much lower voltage than its predecessors. Should I return the RAM and buy another set that suits the 3570k better or would the current set of RAM be okay to use with it?

The motherboard I bought to support this system was

"Should I return the RAM and buy another set that suits the 3570k better or would the current set of RAM be okay to use with it? "

Yes, you should return the ram and get 1600MHz ram rated at 1.5 Volts at 1600 MHz.

Yes, you should return the ram and get 1600MHz ram rated at 1.5 Volts at 1600 MHz.


But since the 3570K apparently skyrockets in temperature as you go past 1.25v or so, wouldn't 1.5v still be too high?

Or is there something between CPU and RAM voltage I'm confused about?

You are mixing up VCore and DRAM voltage. They are seperate. The IMC (Integrated Memory Controller) in both Sandy Bridge and Ivy Bridge run at 1.50v. The CPUs VCore runs differently and normally is around 1.10V for Ivy Bridge (the 3570K) at stock settings, possibly lower if you are lucky.

So no, going to 1.50V RAM will not hurt the CPU. That said, that AData is crap. If you look, good RAM for DDR3 1600MHz runs at 1.50V and normally 9-9-9-24.

That memory is from one of the best memory manufactures in the world and its even cheaper than the AData. I am running 16GB of that with my 2500K and it couldn't be happier.

Don't change the CPU voltage, change the DRAM volts.

Ah thank you very much sir! I'm rather new at this and I appreciate people like you going the extra mile in your advice. I think I will indeed go for those instead, gonna send my ADATA sticks back.

One thing I forgot, I am not a big fan of Gigabyte motherboards so I don't have a lot of experience with them but I am assuming that since Ivy Bridge does support DDR3-1600 nativley you shouldn't have to manually set the timings, frequency or DRAM voltage.

It should rather, like an Asus, just pull the specs from the memory modules themselves (Corsair Vengance is XMP rated) and auto set to DDR3 1600.

That said, make sure they are all set properly in the BIOS and in Windows for the best stability and performance.

Ah yes I did read up on some RAM defaulting at 1333MHz when plugged in without any configuration. I will make sure I double check, thanks!
