Good afternoon everyone,
A friend of mine is having the following experience:
Recently bought a 2600k + i7 Gigabyte GA-P67X-UD3-B3 (updated to the latest version of the BIOS...F6 i guess) and the following memories: 2x2GB Corsair XMS3 DDR3 1333 (CM3X2G1333C9) and 2x2GB Kingston HyperX DDR3 1600 (9905403-151. A00LF). In other words, Four sticks of 2GB each, in total.
The problem is that the PC freezes, a 2~3 minutes after booting the Win7 x64. Then we started some tests, removing and re-placing the memories. And we obtained the following results:
1 - 2x + 1x Corsair Memory Kingston (in all possible combinations of slots. We tested both memories when using only one particular brand combination. In other words, first tried with one of Kingston and then tested with the other) = 6Gb of RAM and PC does not freeze;
2 - 2x + 1x Kingston Memory Corsair (in all possible combinations of slots. We tested both memories when using only one particular brand combination. In other words, first tried with one of the Corsair and then tested with the other) = 6Gb of RAM and PC does not freeze;
3 - 2x Kingston Memory (in all possible combinations of slots) = 4GB of RAM and PC does not freeze;
4 - 2x Corsair Memory (in all possible combinations of slots) = 4GB of RAM and PC does not freeze;
5 - 2 - 2x Corsair + 2x Kingston Memory (in all possible combinations of slots) = 8Gb of RAM and PC
DOES FREEZE;
We were not able to leave a stable system using all the slots (the four memory banks). I discard slots defectives, because we have tried in all slots, with all the memories and the problem does not happen. And it seems there are no problems in memory. Did not try with just one memory ram stick because we have not seen the problem happen using two sticks. By using two or three sticks of memory, we saw that the problem does not occur while the dual channel enabled (in the case of using two sticks) or not (in the case where we use three sticks). I kind dismiss problems of incompatibility between memories because, as illustrated above, the problem does not occur when we use different memories (when using 6GB).
I wanted your help regarding this mystery. I think there might be a problem using dual channel memory with different brands.
Finally, I ask your help.
Thanks!
