790X-UD4P issue

[manimal]

Sorry to be a bother but I have spent the better part of a very rare day off trying to get my new build up. Using the GA-MA-790X UD4P has been very easy till I decided to add ram after a basic build up.

Unless I am a complete idiot it appears that these ram slots are in order left to right with dual channel mode being side to side not every other.

I am completely unable to get the board to recognise more than 1 ram slot at a time. I have tried 4 different sets of ram and even purchased the Corsair TwinX 4 gig kit that is listed as a compatible on the Gigabyte site.

I have updated the bios to F4 and have a 955 in this one with a 4670 for now and tried many clearings of the CMos. CPUZ sees only one stick when 2 sticks are side by side in dual channel mode. I have set voltage and speeds in the bios to what they should be at and even dropped the divider to 663 to no avail.


I am probably missing something easy.....


/thanks

Does the BIOS report incorrect amount of RAM as well?

Yes sadly only 2048 is reported in bios.

Hmm.. Assuming everything default/optimized BIOS with minimal hardware attached, if that's what happens regardless it sounds like the board is faulty. Or the CPU. I say this very, very cautiously because we know CPUs are resilient. But after wasting so much time last year over a simply dead Q6600, I can't say it's never the CPU..

So if I'm understanding correctly, all DIMM sockets on the board works if only 1 stick is used? Whichever socket the DIMM is plugged in? Or is there a certain slot that doesn't work always?

Ya I do think the board is faulty. I put the PH2 710 I had in one of the htpcs in this board and it has the same issue. Since I bought at a frys locally returning it isnt much of a bother. The memory controller seems flaky since it did manage to post a few times with 2 sticks in single channel mode but Bsod'd soon after. I am now trying to decide if I am just going to get another one of these boards or move up to something better. I tried to get some help from Gigabyte but the answers they gave me were almost comical.....

Thx for the help Lop!

Funny thing is I think I am cursed with boards the last couple of years. Sure I may run em hard but after 8 rma'd 680i boards, 2 IP35Es and 3 abit matx boards I should just quit....
