configuring help for gskill ripjaws

post #1 of 19
Thread Starter 
I'm trying to get my G.SKILL F3-12800CL7D-2GBRH sticks to run at DDR3 1600 instead of the default 1333.

I've changed the timing to 7-7-7-24 2T like both the specs and CPUZ say but CPUZ still says they are running at 669 MHz which is about 1333. What should I be doing to get it to run at 1600?

Screenshot of CPUZ:

Comp specs:
MB: Gigabyte 890GPA-UD3H
CPU: AMD Phenom II 965 3.4GHz
RAM: 2x2 GB G.SKILL F3-12800CL7D-2GBRH
HD: Western Digital 1TB and Western Digital 500 MB

Change the memory multiplier to 8X.

I tried changing the mem clock to x8 but I got a boot failure with a message that said:

"The system has experienced boot failures because of overclocking. Last settings in BIOS setup may not coincide with current H/W states."

Then if I continue it resets the memory timings to default.

change multiplier up the vram.

I increased vram to 1.6v like the specs say and still got the same failure. 1.65v and above is shown as red in the bios...I don't want to risk anything going higher...

Up the CPU-NB voltage. I needed to up mine +0.075V at stock timings/CPU speed/NB speed just to get it to work. 1.65V is safe for those Ripjaws, in fact some DDR3 runs at even higher voltage of ~1.8-1.9 without any problems. This is IC-dependent; some IC's are built to handle 1.5, 1.65, 1.8+ or even below 1.5 DRAM volts. Most Ripjaws will work at 1.5 but will also perform well with 1.65V.

Even with 1.65v DRAM and +0.100v CPU-NB it still has the same boot error :/

You could try a different memory multiplier/bus clock (i.e. instead of 200x8, try 241x6.66; lower multipliers for everything else unless you want to OC).

cheap ram doesn't overclock...
try 9-9-9 timing and 2T CR

I'd rather RMA it/exchange it if you can't get it to run at rated settings (if it's worth the time to you).
