Specs:
Gigabyte X48-DS5 F7bios
G.Skill 2x2gb Ripjaws DDR2 1200 http://www.newegg.com/Product/Product.aspx?Item=N82E16820231283 6-6-6-18
Q9550 2.83ghz
WD 640gb hdrive
Sapphire ATI 4870 512mb DDR5
750watt corsair psupply
My issue, I just bought the G.Skill DDR2 1200 memory. set in the bios the settings manually for the memory timings 6-6-6-18 left everything else auto except the voltage which I added +.1 to be 1.9volts. Set PCI express to 100mhz. CPU frequency to 375 and the memory multiplier to 3.20B which sets it to 1200 (recommended settings from g.skills site). Unfortunately I loose a few mhz because there is no ratio to keep my CPU at 2.83 ghz (not a bid deal it runs at 2.81ghz)
Anywho when in games the PC will freeze anywhere from immediately to 30-45 minutes into a game. Occasionally windows with freeze as well randomly. I had issues with this when I had DDR2 800 in my system. The only way I could keep things stable was to set everything in the bios to auto. Which meant my DDR2 memory ran at slower CAS latencies. If I tried to overclock or make any simple change the PC would exhibit the same freeze issues.
I have tried different memory and brands
I have tried different CPUs
I even ran Crossfire for awhile and tried each video card in turn thinking perhaps it was a video card issue. Both cards no matter what slot they were in, if I made changes the PC would lock.
Kind of at my wits end because I can't run this memory without making the changes above to get it to run at the appropriate DDR2 1200 speeds.
Here is the kicker. When I had an nvidia card I could overclock without any issues. ever since I've been running ATI I've had problems if I make any modifications to CPU speed or RAM speeds in the bios.
Any help would be greatly appreciated. its pissing me off.
