I have a GIGABYTE GA-P31-DS3L P31 775 motherboard and had 2 gigs (2 sticks) of transcend memory in dual channel, which worked fine. However, I recently added 2 more gigs (2 sticks) of gskill. When I tossed them in, it freezes on memtest86 pretty early on. Going into BIOS I see the computer automatically sets the memory latency as 4-4-4-12, even though gskill only goes at 5-5-5-15, so I'm wondering why the motherboard doesn't detect the slower speed. I've also tried setting the speed manually to 5-5-5-15, which lets me boot up the OS, but it freezes a little later. Taking out the gskill or the transcend, either seem to work fine. I've also tried setting the memory "speed" to "Standard" from "Turbo", but that hasn't helped. I'm aligning them every other row as I did when I had just two sticks for dual channel, so I don't think that's an issue. Do I just need to micromanage more of the parameters like voltage or something to get this to work or is this configuration hopeless?

Hi and welcome to the forum.
Well it's always more trouble trying to get mixed memory to work together. Although in your case I think it might prove impossible. I have checked out the links you supplied but neither helps for what I think is your problem and that is they are double sided modules. If so the manual says this:
* Because of chipset limitations, do not populate both DIMM sockets of the same channel (e.g. DDRII1 and DDRII2), or populate 4 DIMM sockets with double-sided memory modules to prevent system's failure to start or incorrect detection of memory modules. Please refer to the user manual for the memory configurations table.
