Minimum Settings for Ripjaws Z 2400-10

[Ken429]

I stumbled into the fact that my G3258 cpu did strange things when I had the Ripjaws Z 2400-10 memory installed. Once I replaced the memory with 1.35V 1600-9 memory all was well.

Now, I'm wondering if the 1.65V for the Ripjaws Memory is affecting my ability to OC a 4790K on an ASRock Extreme6 MB. The 4790K refuses to run sable over 4.6GHz. So... instead of buying more 1.35V 1600-9 memory to test my theory is it possible to plug settings in the BIOS that will slowdown the Ripjaws Z to 1600-9 with a lower voltage.

I've tried Auto and that slows the memory to 1600 but leaves the voltage at 1.65V. Can someone give me the absolute minimum settings I need to get this stuff to run at 1600 at 1.35 or 1.5V. Thanks.

Thanks all for the help!

I finally called GSkill Tech Support and they said use 1600 1.50V 10-10-10-30 timings. Seems pretty conservative since most reasonably priced 1600 1.50V memory is rated at 9-9-9-24! Anyway, I dialed it down to the GSkill recommendation and the system would still not OC beyond 4.6GHz. So much for that idea.

It shouldn't, unless you're already super close to being temperature limited and the higher system agent and IO-a/d voltages further reduce the thermal margin. You could just check, by how much these are raised by the MB if left AUTO with the kits XMP enabled and try to manually fine-tune them instead. Depending upon IMC quality of your CPU they might not need to be raised over standard at all.

Keep the RAM at DDR3-1333 or 1600 and see what CPU OC you can do.
