Hello. I love this memory and I've used G.Skill a lot in the past, and I know it's compatible with this board. Here are my specs:
2 sets of dual-channel kit Ripjaws F3 12800CL9D-4GBRL total 4 sticks
GA-790FXTA-UD5 Rev. 1.0 motherboard with latest BIOS (F3F) dated 4-26-2010
Phenom II x4 965BE C3 stepping
Windows 7 64-bit Home Premium
1 TB Hitachi Sata HDD
PowerColor Radeon HD-5870
Corsair H50 Water Cooler
LG BD-Burner
Lite-On DVD Burner
Corsair 950 Watt PSU
Cooler Master HAF 932 Red Dragon Case
Ok, I've ran memtest all night with no problems (with all 4 sticks installed - haven't tried singles yet.) Windows runs great. I've scanned the forums and found that I have to manually change the memory timings to SPD otherwise they default to 1333 instead of 1600. My CPU has C3 stepping so the MMU shouldn't be an issue.
The only time I have issues is running games. If I leave the memory at 1333 then I can play games all day long. But at 1600 (9-9-9-24-t2) many times my games will crash to a black screen and reboot the PC. I've seen on here that I may need to bring up the voltage of the nb, so in the bios I went from 1.10 to 1.175 first. It helped some, but I still had issues. Then I went to 1.2 (cpu-nb setting in BIOS.) That helped more. But then when I thought I was finished, it crashed once more during a game. So then I brought the HT speed up to 2200. I'm not convinced that has fixed the issue yet since I haven't played much after changing that.
I've been building PC's for over 15 years and never tried overclocking, and I put these pieces together because they are very capable of it if I wanted to try it out. I've seen some posts in the forums that suggest either a 1.3 or 1.4 voltage for the nb and I have to wonder how safe that is because in my BIOS, those settings are in a warning zone. I believe the 1.3v is listed in pink and the 1.4 is in red. Just wondering as I don't wanna fry my expensive board. There are two settings for NB and maybe I'm not using the right one? Or are they tied together and just listed in two places? I think one is cpu-nb and the other is just nb? Not sure now as I'm at work and not able to look.
Anyway sorry if I'm long-winded here but I've tried to put in as much info as I can remember about what I've tried so far.
Thanks guys I love this forum!
