Windows 7: RAM problem...

RAM problem...


Today I got in the post my 8 gig G.Skill DDR3 1333Mhz dual channel kit from Newegg, and I was really really stoked about having 8 gigs of RAM with a 7 CAS latency and all, but when I popped that kit in my madreboard and tried to boot into Windows, it epically failed.

So here's what I all did:
-checked in BIOS to see if the RAM's recognized, it is
-changed the RAM voltage to 1.5, no go
-changed the timings, no go
-changed the frequencies, no go again
-did a combo of the three, no go
-booted into Safe Mode, that worked and Windows is seeing 8 gigs installed
-haven't done a memtest yet but I will
-took a stick out and booted into Windows and it worked but the timings are at 9 even though I changed it to 7

I'm thinking it's not a RAM problem but more a BIOS being outdated it seems. I binged around a bit and found a support thread with pretty much the same issue and symptoms and a BIOS update helped, but I don't want to risk killing my motherboard unless I know for sure it will help. So does anyone have suggestions?

Also, I think CPU-Z is off a bit because it detected my northbridge chip as being an AMD 780G when it's a 760G. I don't know...

Here are some setting to try. I assume no responsibility if something fries.

You may not have these same settings....
CPU NB Freq X11 2200Mhz
CPU Freq 200
MemClk, Manual X8
System Volt control-Manual
DRAM Volts 1.6V
NB Volt control 1.40V
CPU NB VID Ctrl +.01V
DRAM, Manual
tRFC 0,1,2,3 - 160ns
Anything under those, on Auto
Timings, 7-8-7-32T
This may under clock your CPU from what you have now but may let the RAM work. G.Skill will help if you email them with your specs.

Check the BIOS update to see if it's been upgraded for differnt Ram speeds/manufacturer first.

Update by the old method of downloading,installing on usb stick and flash from there...updating thru windows is inherently risky.
