New DDR3 RAM

Hi bendyferret and welcome to Tom's hardware forum.

Cna u test the rig with only one RAM stick installed?

Yes, it boots with one or both sticks of the OCZ... but I've tried with both the G-Skill sticks separately and neither work in either slot.

Can u test the G.Skill in another rig?

Yes, the G-skill works fine on a Gigabyte- EX58 UD5, both sticks.

The only difference I can see between the two is the timings... OCZ is 9-9-9-20, G-skill is 9-9-9-24 2N

The only thing that I can thing about this is a compatibility problem since the RAM works fine in other mobo.

That was my first guess, but all the numbers add up...

SHUTTLE:

2 x 240 pin DDR3 DIMM slots,4GB per DIMM (Max 8GB)
Dual Channel DDR3 800/1066

RAM:

8 GB
Dual channel
DDR3-1333
PC3-10666

I see no reason why it shouldn't work.

=(

Ah, funny how its clearer when I write it down. The shuttle takes 800/1066 but the ram runs at 1333. Do you think I can slow it down in BIOS?

By default the mobo select the best speed for the RAM that u install.
