New Build Freezes - Memory Settings?

Wow nkata! That's some achievement; two different makes overclocked, and using all 4 slots on the board? That "breaks" several rules does it not? I wouldn't even think of attempting it. Is it all in the memory specs? Are they totally equivalent? How come you ended up with that mix and what made you think it would run OK in the first place?

I have made huge strides forward this afternoon on my original Corsair memory. The guys at MSI advised I needed a "Command Rate" of 2, not 1. In a leap of faith, I have assumed they meant what my BIOS is calling "SDRAM Cycle Time 1CLK" as that was the only "thingy" I could find with a "1" in it. Can you tell I'm a newbie? After more freezes I discovered this value is in two places, so I changed the other one too, mind you, getting the BIOS to allow me to change the values was a guessing adventure in itself as the menu item that lets you at them was greyed out and the board manual doesn't tell you how to do anything. So I now have a "DRAM Timing Mode" set to "Unlink" from "Auto". The "Advanced DRAM Configuration" option became available by doing that, but, I don't know why or if the new setting is good, bad, or indifferent. MSI said the DRAM voltage needed to be 1.55 or a bit higher, but I remembered what you said about the voltage and I've been upping it step by step; I'm now at 1.659 volts and I've been what I call "solitaire stable" for 3 hours; thats the pinnacle of my game playing ability! I've just unleashed "the player of games" on the machine and I think it will get some serious "minecraft" bashing next, although I'm not sure how much of a challenge rendering boxy lego like graphics will be for this rig, it will be in advance of what I can do t it anyway.

Could it be over? I haven't opened the G.Skill kit in the hope I can trade it for more mundane parts for Build.2

Still need the MSI boys to review what I've done and advise if there is any more. And of course I need to make sure my set-up is really stable.

Huge strides forward! Thanks for all your help nkata and mickyflinn (really pleased with my new PSU!).
 
I purchased the OCZ first, very stable but when I wanted to play with 8Gb it was not being sold but the Geil was on offer. Both are the same cas rating and both seem to play happy with the board. Luck possibly. If 2T works and is stable, stick with it. Unlink will be for custom settings as you have found.If you can stay around 1.6 - 1.65 that is OK, I would be trying to bring it down a bit if stability is assured to about 1.6V.
 
What are the issues with higher voltages?

I have brought it down step by step to 1.645; been using the built-in Win.7 memory test. It actually froze on me first time around using that at 1.659, but a second go was successful?

Thinking back to yesterday and the freezes I thought I got...they could simply have been the computer going into sleep mode...I was leaving it for a while at a time just to see how long it would stay on an even keel for; at 1.659 I nearly turned it off and back on again but realised at that point that it was just asleep.

Worrying thing about 1.645 is that it froze on me in BIOS, once, but that was after a successful Win.7 memory test and a re-boot to get to BIOS; I was looking for fan controls...it made me think back to the MSI conversations I had, one question was about the rev of the BIOS? If the AMD chip is managing memory, why would they be bothered about the BIOS release? Are there unrelated bugs causing it to hang I wonder...I don't have an answer to that yet, no response yet post me advising them of the BIOS rev.

So, still not absolutely sure I am there, but still a lot more stable. I'll get "the player of games" to put it through its paces again later.
