Hey folks.......I'm new to overclocking, but I had a concern about my memory and motherboard combo, I'm getting blue screens over and over. So I just added a new Mobo and new memory, system works fine and boots no problem. The motherboard is an ASRock 870 Extreme3 and is capable of 1600 DDR 3 Ram with OC. I purchased some G.Skill Ripjaw ram (4GB 1600) Using my BIOS i manually set the timings as listed on the sales page for the memory at newegg. I selected the 1600 speed and rebooted. Is there anything more to do? the computer boots into windows 7 and is fine but if I leave the PC idle for about 10 min or so it goes Blue Screen. I went back into BIOS and went down to the next lowest speed (maybe 1366) im not sure. Everything stable. Just wondering if I should have changed any other settings to get the full RAM prowess. BTW CPU is AMD Phenom II X4 840. Thanks for reading and appreciate any suggestions.
