Windows 7: PC Freeze problem (lots of info)

Windows 7 Ultimate 64bit

So.. Anything else I could try?

Windows 7 x64 Build 7000

Same here... my old mainboard died, so I looked up something and found this M4A87TD-EVO, bios 2001. Thought I did myself a favor... sadly I was mistaken.

First usage of the mainboard got me worried as the MemOK! feature would not let me boot. I always had to reset them and retry after a cold boot. Something got lost in between usages. BIOS reset did not solve it.

At first I thought it was my Samsung SSD. Strangely after the last firmware update I got a stable system.

Before, it used to freeze / deadlock out of the sudden, either in boot up (when the windows logo forms) or after several minutes of use, or after several hours.

Eventually I figured it was the suspend / hibernate feature. I did notice the SSD did disable those when Samsung Magician was used so I stopped using them (after manually reactivating them), just shut down and restart and it seem to work, for the past 6 months not a freeze issue.

But recently I got me 8GB of RAM from someone who wanted to get rid of them.

When I got the mainboard I used 2x2 Kingston HyperX 1333MHz. These had to be reset before a cold boot. This stopped after a week or so and booting up went straight through. For 6 months, with latest firmware updates, nothing made any issue. No more freeze ups, no deadlocks. The only time when the system locked was when recovering from hibernation, which I have used only once in these 6 months. After a reboot, all was alright.

Then I installed those Corsair 2x4GB 1333MHz XMS3 XMS3 ? 8GB Dual Channel DDR3 Memory Kit (CMX8GX3M2A1333C9)
First thing was booting up. MemOK! made no issues, BIOS was previously set on SPD and I didn't reset it. Just swapped the kit and loaded MemTEST. It them made issues... it deadlocked during memtest several times. The strange thing was that the + and the pointer were still blinking, but the progress was not advancing and keyboard was not responding. Tried one stick after another and it worked, no errors whatsoever. Booted up into Windows then some hours later it froze. Again, the same way as it did with the Kingstons half a year ago, without suspending or hibernating the system.

I know Asus support and quality went down the drain, the mainboard which I had before was also Asus, M3A78 Pro. It had different issues as it sometimes came out of power outages with the HPET speed up bug.

Might it be the RAM banks?

When I tested the Corsairs, I took out bank A2 stick and left one stick only in bank B2. When I ran MemTEST, the frequency was set to 200MHz (400 DDR), no matter what was set in BIOS. I put the same stick in A2 and it went full 1333Mhz when set or 1056MHz in SPD.

I use the A2 and B2 (black banks) because the cooler is taking up space right under A1 (blue), so I can't get Dual Ch otherwise.

The only thing for me is to go through several months like this and hope it stabilizes.
