Help with Gigabyte 990FXA-UD3 v1.1/F3-12800CL9Q-16GBRL/AMD FX-8150

[zeroarmy27]

My mobo's EOCP sets the memory @ 1600 w/ 11-11-11-39-2T. It runs stable, no problems. I want to tighten up the timings as close to advertised as possible. I'm not very familiar with RAM timing acronyms, so some help would be appreciated. I'm using the F10a BIOS.

Just go in and find the DRAM base timings, where it has them at 11-11-11-39, change to 9-9-9-24, leave CR (command Rate/Timing) at 2T

Booted to Win 7 x64 Pro with no problem on those settings. Prime95 testing is next. If all goes well, what should my next step be?

Thanks!

Prime95+ started throwing errors between 13% and 14%. RAM timings showed up really strangely.

Here are the BIOS settings for the RAM OC:

Any thoughts?

I meant to say between 13 and 14 minutes into the test.

Help please!

I don't want to be needy, but I still need some help! I got a working BIOS profile at 9-9-9-24, but I think I need to add some voltage since it's performing worse with tighter timings. I'll post full settings in a minute.

Test each module individually to see if one performs differently.

Thank you

Try the NB VID at 1.3 and take DRAM to 1.55

[zeroarmy27]

Stable clock found! I only had to change voltages a very tiny amount to get this stable, and I'm sure it's because I'm populating all 4 DIMM slots..
DRAM Voltage: +0.005V
CPU NB VID: +0.10V

Timings:
9-9-9-24-5-160ns-12-6-33-5-1T(CR)
NB @ 2400
HT @ 2600

I shaved a decent amount of latency off without pumping up voltages enough to worry me. Thanks for all the help, folks!

Happy all is looking good, Enjoy!
