Need some help with OCing my RAM.

post #1 of 4
Thread Starter 
Hey guys,

I am probably doing somehting wrong here cause my G.Skills wont even change a single timing no matter what I do..

First a little story of specs:
ASUS P8Z77-V board.
i7 2600K @ 4.8Ghz 1.416v stable.
The Bad Boys: G.Skill RipjawsX 2x4GB 1866Mhz 8-9-9-24-2T 1.5v RAM.

Well, I wanna run this RAM at a nice balance between Mhz and timings.

So, what I tried to do at first was see if it would do 1600Mhz 7-7-7-20-1T. There wasn't even a POST when setting this with 1.6500v vDRAM and 1.2v VCCIO/VCCSA.

Then I tried to see if it would do 1866Mhz 8-8-8-24-1T. Again, no POST / on-off loop before POST with 1.6500v vDRAM and 1.2v VCCIO/VCCSA.

Then i tried to see if it was even stable at it's original settings of 1866Mhz 8-9-9-24-2T 1.5v. Yes, perfectly stable in memtest86+ and runs properly in every day usage.

Now, even changing 8-9-9-24-2T into 8-9-8-24-2T with 1.65v and 1.1v VCCIO/VCCSA won't POST.

Am I missing somehting here? I just wanna run preferably 1866Mhz 8-8-8-24-1T. The 1T command rate is perfectly fine, even at stock votlages and speeds. So, that aint the problem. It's the 8-8-8 thats the issue.

Also, frequency wise, the RAM is unstable as soon as it hits around 1890Mhz. That's shy of a 30Mhz overclock...

So, either i'm missing something / doing something wrong or this RAM is seriously crappy.

FYI, my old 4x2GB Kingston kit, rated for 1600Mhz 9-9-9-27-2T 1.70v, actually runs 1600Mhz 7-8-8-22-2T 1.65v just fine on this board.
Also it does 1866Mhz 8-9-8-24-2T fine with 1.65v. Problem just is that I sold that stuff because it is such a high default voltage. It being almost 4 years old and designed to work on 1.7-1.9v on S775.

I thought those dimms were 1866Mhz CL9-10-9-28 1.5v

Found two reviews with very different outcomes, although they aren't using a Z77 board but it should be of some assistance to you.

It is a CL8 kit. Being this one.

CL8-9-9-24-2T default, only thing I can do stable is 2T to 1T.

I got a similar issue with my ram, I am just gonna run higher frequency.

RAM seems to have its own preference for what it wants to run at, my ram wont do 2133 9-10-11-26-2n but will do cas 10 2400.
I too could only adjust 2n to 1n.
It also wont do cas14 2600, but thats probably not unusual.
