Hello Fellas, I registered here for help with some difficult technical issue due to other HW forums being full of "buy latest anus board" and "buy most expensive corsair" people... Basicly I got the infamous P55 GD65 from MSI with 4x2GB Skill 1600 CL9 Ripjaws. All the time I had the so-called cold boot bug issue. Bios flashes didn't help. So I bypassed the issue with booting twice. However, lately a new issue came up. Out of the blue I get the permanent beep code when booting, but going to BIOS and leaving it bypasses the issue. When the PC is on all I do works without issue except some minor TS3 issues that are solved with a single restart of the program. Currently I do a prime blend test over the night... Didn't find my memtest CD in my personal chaos which makes me do the memtest tomorrow. I wonder whether anybody can help with the issue. I personally think it will come down to a RAM change. However, I wonder which RAMs would be reliable now as replacement. The compatibility list of MSI is a little outdated. Does anybody know which RAMs would be reliable on the board? I personally consider 2x4GB of the present Mushkin Redline 1600 CL7 RAMs as replacement and the GeIL Black Dragon Series was recommended by a friend. The system only used the turbo mode for OC and ran without other issues since end 2009. I hope the recommendation of this page prooves right Edit: the beep code seems to indicate a PSU issue, but I highly doubt that... Corsair TX750W in HAF tower. Addionally once started everything works properly as with the coldboot bug issue. Thing is I wouldn't trust that beep code, if all tests and the PC after start work without issue.
