Overclock Ripjaws X F3?

[humanage]

I have this RAM: http://www.newegg.ca/Product/Product.aspx?Item=N82E16820231426&cm_re=ripjaws_x_f3_p67-_-20-231-426-_-Product
I don't know much about RAM OC'ing, but I have an MSI P67A-GD55 Sandy Bridge setup. The RAM is 1333MHz, but comes in 1600, 1866, and 2133(come with a cooler). I'd like to get to at least 1600MHz. The only difference between my RAM and the 1600 is the speed. The stock voltage is 1.5v. How far should the voltages go (MAX), and how high should I raise timing (stock ar 9-9-9-24-2N)?

The ram in that link is 1333mhz ram if you own that ram;
YOu just have to raise it to see where its stable I run my 1600mhz ram at 1704mhz
Adjusted my 9-9-9-24 to currently 7-9-7-24 the middle number i cant change or cpu wont boot.
I left my voltages on auto.

Id think you can run that ram at like 1500-1600 no prob. I use a fan on mine. keep to voltage on auto or set it on or just a tad over stock setting.

The only thing you can really do is try increasing the RAM voltage (and maybe VCCIO/VTT) and setting it to 1600 to see if it works. You may also need to make the timings 10-10-10-27 or worse.

Do not go beyond 1.65v for RAM voltage, and 1.4v is the maximum for CPUIO/VTT.

Note that you actually won't be able to tell the difference between the RAM speeds unless you are running benchmarks. There will only be a few frames difference while gaming, and you can't distinguish that -- it's like 2-3% or so, and you can only distinguish differences of 10% or higher.

Okay, I've not been able to raise the speeds well, but I got my timings from 9-9-9-24 to 8-8-8-24 so far.

well, if you raise the bclk it should raise the ram freq,

Thanks, but isn't Sandy Bridge BCLK supposed to be left alone?

 

[natefostersr]

just looked it up yea apparently nobody got over 107,
heres a guide i found interesting - http://www.clunk.org.uk/forums/overclocking/39184-p67-sandy-bridge-overclocking-guide-beginners.html
