I recently built a PC using these parts: XFX ATI Radeon HD 4890 1024MB GDDR5 PCI-Express Graphics Card 4GB G.Skill RipJaws 1600MHz DDR3 Dual Channel Memory Kit 550W OCZ Fatal1ty Modular Power Supply Gigabyte GA-P55-US3L motherboard 1TB Samsung SpinPoint F3 HD BX80605I5750 - Intel Core i5 750, S 1156, Lynnfield, Quad Core Xigmatek Midgard case Arctic Cooling Freezer 7 Pro Quiet Intel CPU Cooler Windows 7
Each morning I get various BSOD's, but if I remove 1 stick of ram the PC boots without a problem. I then can switch off put the memory back in, again the PC boots without a problem and will run perfectly well all day, restarting as often as I like.
I have run memtest86 on the individual modules of ram and on the 4Gg total and no errors found.
The BSOD's are varied in the error codes but I'm am leaning to wards a hardware fault, but am open to any suggestions.
Try manually setting the RAM frequency in the BIOS so it's running at 1600Mhz. You may also need to play about with the RAM voltages & timings. Do only ONE change at a time, & each time test to see if it has made a difference.
Sometimes, high-end RAM will only run or run best without problems at its rated frequency, voltages & timings. G
