DDR3 Upgrade problem

  arakis777 14:27 21 Jan 2009


I recently built my new machine using an ASROCK P43Twins1600 Motherboard with an Intel E6600 Dual core processor and 4 x 1 GB sticks of DDR2 memory. I run Vista ultimate.

I decided to upgrade my memory by replacing DDR2 memory with 2 x 2GB sticks of DDR3 1333Mhz. The BIOS picks up both fine and as my motherboard is meant to support this memory at FSB frequencies of 1333 and 1600 I can understand why I can't seem to get past the login banner. I don't get any error or blue screen of death. Do I need to re-install vista or worse still change my CPU? Please help

The motherboard supports FSB1600/1333/1066/800MHz CPUs and the E6600 is 1066MHz so that should be a problem.

Do you have to change a setting for DDR3? Also the voltages may need to be set manually although they should probably be lower than DDR2 voltages.

You could try fitting just one stick at a time.

I meant 'that shouldn't' rather than 'that should'

Something else to try is to reset the BIOS.

Thanks for your help Spartacus. It looks like the problem was faulty memory. Now resolved after exchange....

Best regards.
