4Gb Corsair XMS3... 15.v or 1.65v?

snadge · 12 Jul 2011 at 22:01

is this RAM 1.5v or 1.65v...?

I have read on other websites people buying these sticks to find 1.65v on the chips and having problems running them at 1600mhz

I want them for a sandybridge setup to run at 1600Mhz... ive been told to buy 1.5v??

can anyone clear this up for me?
do I have to up the voltage to 1.65v to overclock to 1600Mhz?

this is mobo http://www.overclockers.co.uk/showproduct.php?prodid=MB-324-GI&groupid=701&catid=5&subcat=1906

thanks

Many people have this RAM for Sandybridge and use it at around 1.5V for 1600MHz.

I assume you're referring to this.

As above - OcUK have had sets running happily at 1.35V.

Hi there

In our testing we've seen this memory run happily as low as 1.35v, so set it to 1.50v and you should be fine.

thanks, what will it default voltage be in that motherboard? http://www.overclockers.co.uk/showproduct.php?prodid=MB-324-GI&groupid=701&catid=5&subcat=1906

will I have to change it? I was told I could just put in XMS3 and change speed to 1600Mhz without touching voltages...

also...will Corsair Vengeance Low Profile stick do? these have same timings and XMP

thanks

It's advisible to set the voltage, timings and frequency manually - it's best practice. Or you can enable the XMP and just change the voltage.

Don't know from personal use - but I would be surprised if it didn't run under 1.55V as most brands of DDR3 within that spec do - but you may need to consider the profile depending in your cooler.

they are 1.5v sticks

The Vengeance are 1.5V

The XMS3 just happen to run at around 1.5V but are technically rated at 1.65V.

Then yes they will do - depending on your cooler.

EDIT: Although i would still advise you to get the XMS3 at £30
