As noted further down in this forum, I tried to change PC cases over the Holiday weekend to get more cooling and to try a water cooling solution (I was only changing the case when this occurred, not the CPU cooling), but somewhere in changing the mobo/CPU/Memory, PSU, etc. to a new case I seemed to have broken something, as I cannot even POST now. This was an older P6X58D-E.So, now I have a new P8P67 Pro Rev3 mobo on order with an i7-2600 that will at least get me started into the Sandy Bridge world.My question- the P6X58D-E has Kingston Hyper X DDR3 (3 sticks X 2GB = 6GB). This is rated at 1.65 volts. It seems looking at the P8P67 manual that the memory used there is ask 1.65V. Will the memory from my old system work in the new? I realize that thus would be 2X 2GB = 4GB, and that i might want to go up to at least 2X 4GB later.Any thoughts are most welcome. It's no fun being FSX-less :)Thanks, Bruce.

I think it is the voltage that counts in the DDR3s and you have a 1.65v whic should work with the P8P67.I have one and use 1,5 v DRAM which is actually what is called forBut the 1.65v works well too just cannot overclock as much or as high.

But the 1.65v works well too just cannot overclock as much or as high.

No need to overclock the RAM if it's 1600 or better anyway. Besides, >1.65v is a no-no on Sandy Bridge. I'm using the 1.65v Corsair 1600 Dominator kit on my rig (see signature). Mainly because the heat sink design went well with my system. That kit will work, Bruce. Though SB is dual channel and not triple, just populate the proper DIMM slots and voila.

Thanks Peppy and Zach- sounds like I am fine to use my existing memory.I appreciate the replies. Thanks, Bruce.
