I have my CPU Core Voltage set to 1.3V which under load pushes at max between 1.325 to 1.35 (depending on my settings). I take your point about 4 sticks of memory, that is supposed to be not as effective when overclocking.
Yeah, starting over from defaults is a good idea. Thank you for your feedback,
. It is very much appreciated. YOU ARE THE OASIS IN MY DESERT OF GRIEF!!!
Part of the problem has been the motherboard, which is actually great except for the fact that I have spent six full weeks trying to ensure I get my money's worth. Of course, having spend six weeks on anything you sort of lose that argument, doh.
I have indeed tried 1.35 and lower. At that level, Windows will not boot, and if it does, a blue screen follows closely after. 1.36 is the best I can do, and at that point, Cinebench no doubt will freeze and HCI MemTest reports memory errors. The same for 1.375 but longer Cinebench executions and less memory errors (but still... memory errors).
It's gotten so bad that I thought it was the memory, even though I checked it with MemTest when I first got it and it turned out OK at 2400, its default speed.
I went ahead and tried 2900 a few days ago and it was OK there, using the XMP Profile 1 setting.
From there, I can bump it up to 3000 and 3066 no problem. This was the same experience I had with another chipset I was looking at (you can see both of them in my sig -- take advantage of my laziness LOL... I ended up with the Hyper-X set).
However, going beyond that is the source of all my ails. I have a 3300 rated chipset but the best I can do is 3133, and even then it's memory errors after testing for a few hours -- insanity!
And so yeah... that four-chip set is what is taking me for a massive ride of failure here. I have been tempted to simply remove 2 chips out of my motherboard to see how fast I can get to 3200 w/o errors, but I am sure I can do it. In fact, I was able to get 3200 to POST no problem w/ only 2 chips in. With 4 in, I cannot get it to post unless I put the vDRAM to 1.45 (maxed out, essentially).
