I just bought these for my IP35 Pro Mainboard. I opted for the 2x2GB DDR 1000 Chips.

I'm experiencing an issue though.

When I use both chips in Dimm Slots A. The system will post and boot up fine.

When I try use Dual Channel I.E - use one chip in Dimm Slot A and One in Dimm Slot B. The sytem will not post. The mainboard gives me an error code of C1.

I have selected the correct voltage in the BIOS but still this doesnt resolve my issue.

I had the same issue with some Corsair DDR2 PC6400 RAM. I don't think its the RAM.

Is this issue happening because there are too many issues when attempting to use all 4 slots or one of each?

I need to know if my board is faulty.

Please advise.
