Problems running mem @ 1066 frequency. Have tried all settings recommended on this forum that pertain to same mem and gigabyte boards. That was with the F3 BIOS. Gigabyte this week released a F5 BIOS for said board, to which I installed. Seems to be more stable then previous one, but stills get BOD at some point or another. Can you help me G Skill Tech?

OK, timings at 5-5-5-15. command rate 2T, voltage 2.1 (can prob drop to 2.0 when stable), tRFC to 70. If stable at these settings can prob drop tRFC a bit at a time. If not stable may have to raise NB voltage a tick or so.

Ok, so I am currently running with what you have told me with the exception of the tRFC. There is no setting for 70, however I do have 75, 105, 127.5(default), 195, 327.5. Therefore I set it to 105 for now, as it would not boot properly set at 75. Also, I raised my NB Voltage to 1.375 which is only three steps above default of 1.3. Seems ok for now. I'll post back should something arise.

Alright, things seem to be running stable @ 1066. NB voltage 1.2 and tRFC @ 127.5ns. I have also set my DIMM Voltage to 2.1 for now, and my timings are 5-5-5-15. I am going to attempt to drop that to 2.0 but not right away. I'll post once I do. Thanks

Ok, this board is for sure not stable unless the VDIMM Voltage is set to 2.1v. Tried even @ 2.050 and 2.0 but no go. So there we have it. Love this board anyway, very nice! Thanks to the G Skill admins and mods for your assistance. It was a pop shot buying this ram but i am pleased with it, and would purchase again in the future.

hello, there..
Won't go with 2.0-2.1v. It simply isn't gonna work on this board. The boot issues seems to be basically sure caused by motherboard voltages, but the main issue on 1066Mhz after it boots up will still be on memory voltage.
CL5-5-4-14 should be just fine on 2 sticks on 4 sticks lose it to 5-6-6-18 and drop the tRC some hammer 33T should do.
(This is my suggestion/advice is drop these on Memtest86+ as long the Test 5 fails (run the couple second test in full) increase the voltage all the way up to 2.20-2.30v, if needed.)
-edit-
fail to mention you might wanna add tRRD equal as the tRCD in all helps on stabilize for start.Last edited by genetix; 08-30-2009, 01:51 PM."Sex is like freeware, shareware on weekends. When do we get to open source?" -TwL
