Help with Kingston HyperX

Ynot · 1 Feb 2012 at 15:55

Could you please tell me what setting this memory should be running at in the BIOS. I want to make sure its running at its best.
Kingston HyperX Genesis Grey 8GB (2x4GB) DDR3
https://www.overclockers.co.uk/showproduct.php?prodid=MY-094-KS

I have four sticks (16gig total) and have an Asrock Asrock Z68 Extreme7 MB.

Thanks.

I have mine running at 1600mhz @ 1.55v in the BIOS without issues.
Running this on a Gigabyte Z68 UD4, With 16gb.

Thanks RJC, I'll have a look.

Just enable the XMP profile and then manually set the voltage to ~1.5V or a little more if needed (maximum 1.575V).

OK Surveyor, I'll try that.

Thanks.

I got that ram and was having problems @ 1.56250v 1600mhz. the ram states it should be @1.65v. I have now been running on 1.65v with no probs but have concerns as people are saying this is to high with sandybridge.

So today I have reduced to 1.575v as Surveyor suggests. This is on an asus z68 deluxe board and I will see if the problems return.
Can 1.65v damage a sandy cpu and or mobo?
If so, then why is this ram recommended to be run @ 1.65v 1600mhz?

I have the RAM, and at 1.65 it was causing boot problems (windows flag loading thing was all juddery).

This time round it's running at 1.5v and 1600mhz and it appears to be fine, nice and speedy etc.

Might up the voltage to 1.55 to see if that makes it any better performance wise.

Hi folks,
would love to hear more on this,
I have the same ram (8gig 2x4) was thinking of another 2x4 to give me 16gig.
But bit worried after reading a lot of things about the voltage and 4 sticks filling all 4 slots may or may not give trouble

Any more thoughts ?

Fine for me 16gig @ 1.5v for months now.

in response to op, your ram settings should be 9-9-9-27 2, 1600mhz 1.5v but increase the voltage if needed.

Upped mine to 1.55v just to get it closer to rated voltage.

OK, thanks Surveyor after putting voltage to 1.575 I have had zero probs so really pleased with that. Thanks.

Looks good mate.

There are other platforms besides Sandy Bridge

Is that @ 4.6GHz using the preset OC profile ?

If it is, on my 24/7 settings

I disable spread spectrum
set vcore to offset +0.01 (gives 1.312v under load)
CPU LLC to level 4
CPU PLL voltage to 1.709

Hi Davefran, yes I thought I would change to the 4.6 OC preset and so far I have no problems.

Should I also change to your advised settings in the BIOS?

Thanks.

Davefran · 11 Feb 2012 at 13:42

Wouldn't hurt to try it

You may have to use a slightly different offset, as not all CPU's are the same obviously.

Ynot · 11 Feb 2012 at 22:05

Thanks Davefran, so just leave well enough alone.

Thanks.
