Hello everyone, I'm building a computer for my internship, it's one that I can do 3D work on. I got the parts today however, I'm running into a roadblock. I have: Core i7 920 ASROCK X58 Extreme Mobo 6 GB (2GBx3 sticks) Corsair XMS3 DDR3 ATI 5770 Seagate 500 gb hdd My problem is most likely with either the motherboard or RAM modules/timings. What happens is that I can only install 1 stick of RAM at a time. The computer boots perfectly fine with just 1 2GB stick in it, but as soon as I put another in it gives me the LED code "38" which means "Initializes different devices through DIM." According to the mobo manual. Whatever that means, I don't know, but it sounds like it's just trying to link some things up in the RAM and it's getting stuck during the process Now what's even more strange is when I have all three sticks of DDR3 in the machine, it gives me the LED Code 6A. My problem with the LED Code 6A is that there is no documentation for it, the mobo manual does not say what that means. I have tried installing all 3 sticks of ram by themselves into the first RAM slot, and the computer boots with all 3 RAM sticks so I'm going to assume the RAM is not bad for now and leave a memtest86 test till I have tried everything else. Something noteworthy is that my bios settings (when booting up with 1 stick of ram) shows the RAM timings to be incorrect compared to what is written on them. I don't have them in front of me right now but the ones on the RAM stick said something like 9-9-9-14 and the RAM timings in the bios said something that began with an 8. So my next steps are going to be trying to manually program the RAM timings into the bios and see if that works.. I also have a 4 GB (2x2GB sticks) Kingston RAM laying around that I will try tomorrow. Do these sound like adequate troubleshooting steps? Maybe someone can make more sense of this for me, would timings alone cause the mobo to not even show video on the screen?
