pdegan2814 Posted March 5, 2013 Share Posted March 5, 2013 Lately I've been having some weird problems with one of my machines at home. The core specs are: Gigabyte Z68MX-UD2H-B3 intel Core i3-2100(not overclocked, using the on-die VGA) 16GB(4x4)GB Corsair Vengeance DDR3-1600, not sure of exact model, pretty sure it's CMZ16GX3M4A1600C9B I started getting some intermittent errors in a problem which the author says *could* be symptomatic of bad memory, but I also knew the hard drive in that machine had seen a LOT of use. The machine would also lock up from time to time. Then more recently(the last few days), the system began responding VERY slowly. Like, I would right-click on My Computer and it would take nearly 10 seconds for the menu to pop up, and other forms of sluggishness. Eventually I decided to replace the system drive and just reinstall Windows 7, start fresh. On that machine it's pretty easy to do, there's only a few programs running on it. But I seem to be having the same issues. The Windows re-install went SLOOOOOW, and the inevitable download of 300MB worth of updates as soon as the install finished took FOREVER, the installation of those updates took even longer. I STILL haven't been able to get Service Pack 1 to finish installing successfully. And this was after installing the various drivers for the motherboard devices. I began to think it might be the memory after all. I'd tried running it using the XMP at 1600MHz, and at 1333MHz, same result. So I burned Memtest86 to a disc and ran it with all four sticks in. ERRORS GALORE, like hundreds of them(sorry, I'm writing this from work and don't have the output in front of me to refer to). So, time for process of elimination. I tried each stick by itself in slot 1, ran a full pass until Memtest said it was clean and I could stop(I know many say to run it for a lot longer, but I just didn't have the time). All 4 sticks ran with no errors. So I tried the last stick in each of the other memory slots, and slots 2 & 3 also came back clean. The test on slot 4 was still running when I had to leave for work. Assuming it comes back clean, my next test will be a pair of sticks, set up for dual-channel mode, giving the machine 8GB to work from, and let that test run for several hours. If it turns out that machine just isn't stable with all four memory slots filled, it can get by alright with 8GB instead of 16GB. I may pick up a 2x8GB pack at some point for it. Few questions: *could it be that all four sticks are good, but the board just isn't stable with all four slots filled? *would nudging the memory voltage up a bit help with stability? It's currently running the default 1.5v, should I try going higher, like 1.65v? *Is there another likely cause for this type of behavior that I'm just missing?
