[Solved] Corsair Dominator problem

I have 2 kits of Corsair Dominator DDR2-1066 (2X2GB) memory, but I have not been able to run them both in the same machine.

http://www.newegg.com/Product/Prod [...] 6820145214 (They cost a lot more than they used to. When I bought mine, they were running $69 per pair.)

I've tried downclocking them to 533, adjusted the timings down, and changed the command rate to 2T, but I have just not been able to get it to run stable. This is on a Gigabyte P35 board, a Gigabyte P43 board, and 2 different Asus P45 boards, so I know it's not the boards causing the issues.

Anyone else have trouble with this memory? Anyone know a solution?

You might try updating the bios to see if there are any updates referring to RAM. I have had problems in the past running 8 gigs of RAM. It is not likely a bad stick of ram, but worth mem testing just to be sure. I had more trouble with a board that had a max memory of 8GB than a board with a max of 16GB. The 16GB I had no problems from the get go with the exact same memory.

Have you run memtest? And do both sets run properly when you run them individually? I would make sure to run memtest to make sure you don't have a bad stick. Other than that, nothing comes to mind other than bios updated, which you've already tried (and with 4 boards, you'd think one of them would work).

Have you tried each stick by itself? Also- did Memtest give you any errors? What is the slowest clock and loosest timings you have tried running?

I think I'm going to go ahead and get new memory. Do you know of any cheap, decent quality DDR2-800 that would work in 8GB configurations?

I've not heard of that for your particular issue, but its worth a try before you RMA and get new RAM, especially since the Corsair Dominators are generally known as really top-notch parts.

yeah, they're 2 identical sets of the exact same memory, version 3.1. I tried it out last night and it seemed to work. I didn't do anything excessively memory intensive other than start up WoW and exit back out, but it stayed stable while I was doing my Excel homework. I'll test it further this weekend when I get the chance to game a bit, but tonight is for more Excel homework. (I hate that class.)

I'm not worried about getting the full 1066 now, 800 will work fine. I just want to get them all stable.

With my NB, the base voltage is 1.1V. 1.4v sounds kinda dangerous. I started at 1.2v so far, but I wasn't able to test very far. Apparently, one stick is bad, and I put in an RMA request for that pair.

I went through and tested one at a time just as I got started because I got a bluescreen I hadn't had before. one of the ones that was sitting around in a static bag gave me some single bit errors, even running at lower speeds. I'll try again as soon as I get the replacement pair.
