Upon Ace-A-Rue's advice I'm posting my problem here and hoping someone can get me straightened out. Just upgraded my computer to a Gigabyte GA-X48T-DQ6 mainboard, an Intel e8400 processor, and 4 gigs (2x2048) of G.Skill DDR3 1600-HZ memory. I also added a Silverstone Strider 850w PSU. My problem is that I cannot get the G.Skill memory to run at DDR3 memory speeds. My processor is currently set at 3.00 GHz (333x9) while the memory is running at 1066 mhz with 1.5v. I've been trying to run a small OC of 3.2 GHz (8x400) and the memory set at 1600 mhz. Every time I change the FSB to 400 and boot into windows within a few moments I get a BSOD. I've tried using that Extreme Memory Profile (XMP) set to Profile1 and both System Memory Multiplier (SPD) and Dram Timing Selectable (SPD) set to auto and booted back into windows. This lasted the longest sofar, almost 10 minutes before the BSOD came. What am I missing? Below is a listing of the settings I'm currently running in the MIT. One more question, what voltage should my processor be set at an OC of 3.2 GHz.

This is your ram ??
G.SKILL DDR3 PC 12800 CL7

first thing you need to do is up the DDR3 Overvoltage Control , Normal = 1.50v, at 1600Mhz your ram needs 1.90v so you need an overvolyage of +0.40v

try that & see what happens if it still fails try increasing (G) MCH Overvoltage Control to around +0.20v

the one thing i noticed about this board is the fact it will run at 1600 mhz in memory speed but everything needs to be in auto and that little gem makes the cpu underclock, which i do not like

My processor is currently set at 3.00 GHz (333x9) while the memory is running at 1066 mhz with 1.5v.

i am afraid you are going to need to increase your Vdimm...1600 mhz memory speed is based on a minimum of 1.9v Vdimm.

I've been trying to run a small OC of 3.2 GHz (8x400) and the memory set at 1600 mhz. Every time I change the FSB to 400 and boot into windows within a few moments I get a BSOD. I've tried using that Extreme Memory Profile (XMP) set to Profile1 and both System Memory Multiplier (SPD) and Dram Timing Selectable (SPD) set to auto and booted back into windows.

One more question, what voltage should my processor be set at an OC of 3.2 GHz.

using that "Extreme" profile is pushing it without having proper voltage to back up the very tight NB latency timings that Extreme calls for...so MCH and Vdimm have to be there to make it work without any BSOD.

i've made some recommendations in red next to the bios setting that might need to be addressed

START with those voltages first to make sure everything is stable; once satisified, you can start reducing the voltages to find a lower value that will work...remember, your memory (same as mine) is rated at 1600 Mhz @ 1.9v for Vdimm...

i tried the above settings and it is working so far...i did have a problem in the beginning when i used CAS=7 and STATIC tREAD Delay=7...when i raised them to 8 and 8, all seemed to settle down...i ran 4 cores on Super_PI 1M and it hung in there with the above settings...now i am running wPrime (both benches)
