Ram ratio is fine. It is just a divider to set the ram speeds. Your ram is at 1600 MHz so that is fine. (Sandy Bridge overclocking means you do not touch BCLK, so you don't have to worry about dropping memory dividers for your memory.)

Run both. 1-2 passes of memtest. Then run prime95 with custom blend of 7GB of memory used to test your ram and CPU overclock.

You may have to increase your VCCIO voltage a few notches if you are unstable [VCCIO is for the integrated memory controller (IMC) in the CPU].

okay so I just ran memtest for an hour and a half and I got zero errors. I went into my bios afterwards just to check everything and I noticed that my RAM voltage is in the 1.63-1.65v range (set at Auto). Is this a normal range? because on mushkins site it says 1.5v. CPU is at 4.5ghz / 1.3v (C1E and intel speedstep are enabled. mobo doesnt have an offset option)

I will run prime95 through the night tonight just to make sure everything is all good. I survived a 14 hour prime stress test a few days ago so things should be fine but I will do it anyways just to stay on the safe side.

Auto voltage seems bad.

I'd set the voltage to whatever it says the stock voltage is, which I'm assuming is 1.65v?

edit: Oh, I see, supposed to be 1.5v. Set it to 1.5v and run memtest again.

okay I will set it to 1.5v (or close to it, maybe a little over like 1.51v because for some reason when I was in my bios earlier I didn't see a 1.5v option and I can't manually type in the number I want, there is just a list of voltages to choose from). I'm assuming anything between 1.5-1.51v would be pretty much the same thing. Then I will run memtest again funfun

okay so I just changed the auto voltage. It would only let me change it to 1.507v so I'm assuming that that voltage is okay. It seems like the voltage dips below 1.5v though sometimes, it doesn't just stay at 1.507v. When I was checking my settings I saw that it went to 1.488v. I ran memtest for almost 4 hours and got 4/4 passes so I guess it doesn't matter if it goes a little below 1.5v.

Your fine! !.507v is good, nothing to worry about!

I have been having issues with Corsair 1866 MHz RAM on an AM3 processor and AM3+. Obviously the max I can run is 1333 mhz until Bulldozer's come out, but it is only running around 700 mhz.


This is strange, because in the bios it is set to 1333 MHz. Is it throttling itself? Even in benchmarking it doesn't budge, and its disappointing, as I want my RAM running to its full potential.


Edit: Read the first few posts, so basically its 688.4 mhz times 2=RAM frequency? That puts my mind at ease.

Yah I guess so. The CPU-Z memory tab seems to be the only thing that shows the correct info. So if you have 1600mhz ddr3 ram it should say 800mhz, etc...

And I guess my computer shows PC3-10700 even though it's actually at 12800.

Does anybody know how long I should run Prime95 for the memory test? I know that testing your CPU OC stability in prime is usually 12+ hours which my OC survived with zero errors before. Do I have to run it for 12+ hours just to test the RAM or is a few hours good enough?
