Hello, I recently bought 1 stick of 8 gb memory and since then, I've been encountering random BSOD messages. My first thought was to run a Memtest, which I ran for 8 passes with no errors. I have also followed the other advice on the announcement topics before making this thread. It's also worth noting that I have a rather large CPU cooler which blocks 1 DIMM slot. If I put RAM in the slot just left of it, the PC won't boot up at all (and this applied to my old RAM as well). Would it be best to remove this cooler and use a smaller one? I'm guessing that, in spite of the Memtest, it would be best to return the RAM. However, I wanted to check to see if any solutions can be determined from the minidumps beforehand, which I will enclose with this topic. I don't know if this would help, but here are my other PC specs, as well as my previous RAM and my current RAM: OS: Windows 7 Home Premium 64-bit Motherboard: Asus P8Z68-V/GEN3 ATX LGA1155 CPU: Intel Core i7-2600K 3.4GHz Quad-Core CPU Cooler: Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing Storage: Samsung 830 Series 128GB 2.5" SSD and a 1TB Western Digital External HDD GPU: EVGA GeForce GTX 560 Ti 448 1.25GB Case: Antec 900 Old RAM: Corsair Vengeance 4 GB (4x1) DDR3-1600 Current RAM: Corsair Vengeance Low Profile 8GB (1x8GB) DDR3 1600 Thanks in advance for any assistance/advice!
