Kingston Hyper X Blu

[Jestahr]

Hey guys,

A while ago I mistakenly bought some Hyper X Blu 1600mhz @ 1.65v.

I didn't realize it was 1.65 at the time but ended up keeping it in my ivybridge rig. It defaults to 1.5 @ 1333mhz. It doesn't support XMP as far as I'm aware and I've never bothered tinkering with it.

I have a decent knowledge of overclocking, but because I was always told never to go above 1.5 with sandy/ivy I just left it as it is.

Question is should I OC the ram or just fleabay it and buy some decent stuff? Would I even notice any performance boost? Only got 8GB installed atm, noticing a lot of next gen games have 6/8gb recommended RAM so thinking now would be a good time to get 16GB, despite the fact prices are a bit steep.

The real world performance difference isn't high. 1.65v is perfectly fine on sandy/ivy as far as I'm aware. Plenty of people, myself included bench a lot higher than that on air.

I have 4 x 8GB of HyberX Blue running @ stock 1600mhz but with slightly tighter timing at 9-9-9-24, on Haswel i7. This memory

The memory is rated at 1.65v but wait for it, i'm running it at 1.35v, yes 1.35v! Totally solid and stable for over a month like this.

So try and undervolt your memory if it's anything like mine it should at least meet stocks speeds at 1.5v. Kingston memory is very good memory, it's just not as fast as others clocked higher. Higher memory speeds make very little real world difference anyway, personally I would just try running stock with the lower voltage.

Your memory probably has an XMP profile.
9.9.9.27 1600
AUTO will most likely set 9,9,9,24 which your memory will probably work at.
But use the XMP profile if available.

As to the voltage stop worrying about it.
If you use XMP and 1.65v is set you can reduce this yourself if it troubles you.
A compromise is to set 1.575V.
I run all my Kingston Hyperx 1600 at that.

If you have only 2 dimms set 1T
If using four 2T is a lot more stable.

The high speed memory kits all use 1.65v.
IVY doesn't come to any harm if you are using 1.65v
The 1.5v myth is spread by folks with very little real world experience.

To damage the IMC you have to use extreme voltages.
There are folks who use 2V+ when benching.
They are the ones who will report degradation or IMC death but it is par for the course for them.
