Ok so I had this board for about 1yr and half gotta say love it.

Here my setup:

Gigabyte GA-MA790X-UD4P

4x G Skill F2-8500CL5D-4GBPK @ 800 (ill explain why 800) = total of 8gb

Phenom II X4 955 @ 3.2

XFX PVT95GYDQ3 GeForce 9500


WD 500GB

CM Stacker 830 Evolution

For some reason if I try to overclock G skill to 1066 (which is standard speed it should run @) I get blue screen until i reset my BIOS.

I went to G skill forums tried everything they said but some many people post kinda about other question in my thread kinda gave up.

Here that forum

Just wondering if any had this issue and if they found a solution

I went to gskill forum but there forum a mess people keep posting diff problems so i figured let me try here

Hi newcomer and welcome to the Tom's hardware forum.

What settings are u using for the 1066 speed?, Can u post the link of the RAM?, Are the 8GB from the same manufacturer and model?

Its worth pointing out here that the Phenom does NOT officially support 4 1066 DIMMs, though some can get them working. I suspect that is your problem here. Officially its a max of 2 Dimms (one per channel running dual channel).

But post your specs as Saint19 requested. Some have succeeded with 4 1066 and maybe saint or someone else with more experience with this topic can walk you through it.

This pdf offers some of the extended settings used on an intel board. At no point does it mention if the chips have been tested on an amd platform.
One thing is clear, you need to set for 2.1v and with amd platform you may need to kick up the cpu memory controller voltage another 0.1 volt to get it to work with 4 dimm chips. The timings used should be usefull since they will have to be set manually. good luck

ok for some reason i did not get an email about your guys post until today but any way to ans your question saint yes it all the same sticks. 4 sticks of gskill.

I am going to try your solutions tonight and take screen shots and post them up.

I did also see that there was a bios update so also gonna do that (note its not beta i dont use beta bios)

Thanks again

Ok pictures came out like crap so i typed it this what i did no dice

Memory clock - x5.33
DCTs - unganged
DDRII Timings manual

CAS# latency - 5T
RAS to CAS R/W Delay - 5T
Row Precharge Time - 5T
Minimum RAS Active Time - 15T
1T/2T Command Timing - 2T
TwTr Command Delay - 3T or 4T
Trfc0 for DIMM1 - 195ns (tried 127 as well)
Trfc2 for DIMM2 - 195ns (tried 127 as well)
Trfc1 for DIMM3 - 127ns
Trfc3 for DIMM4 - 127ns
Write Recovery Time - 8T
Precharge Time - 3T
Row Cycle Time - 42T
RAS to RAS Delay - 4T
lue screen
Increase DDR2 Voltage to 2.0V (tried 2.1V)
Northbridge Volt Control to 1.4V
SouthBridge Volt Control to normal
CPU NB VID Control to normal (tried 1.25V messed my box up)
CPU Voltage Control to normal (tried 1.45V but got blck screen of death)

**When i have DDR2 Voltage to 2.1V i get into windows and blue screen... When i do 2.0 it just locks up while its loading windows
