Very strange problem here, I have an older ECS 915P-A Rev 1.1 board with the full two sticks of 1 Gig memory DDRII. Everything works fine for an undetermined time and then when you least expect it a blue screen happens. Most of the time you have to remove one stick of ram and reboot, it will not reboot with both installed. I have already replaced both sticks of ram and the problem although it takes a long time to re appear it does eventually come back. I am using two sticks as I type this note and have had it running with one for several months since it would not reboot with both, I suspect the ram needed to be started from the slot one and then shut down to install the second stick, after that it boots normal and I have a fast machine again. The first time I noticed something wrong was with large downloads, I routinely download the UDK SDK monthly and they get larger by the month. It always finished the download but the archive or rar always had an error, it took forever to figure out the ram was responsible for the damaged downloads. I fully expect at some point for this too happen once again and I plan on using a newer dual core machine soon as I put more ram in that one. Since this machine is still normal in every way with the exception of that ram issue I would like to continue using it. Does anyone have any suggestions I might look into or try, I ran mem test and everything you can find and see nothing wrong. ECS does not sit at the top of the list for the finest boards but I have to say this one has been a good one for a small budget. I know all things die eventually and if changing the board is the only alternative I'll do that, but try and find a slot 775 that can use this memory because it is very new. Any thoughts would be appreciated.

the ram could be stresing out a weak memory controller. are you using dual-sided ram? perhaps 4 banks of ram stresses it out, and the memory controller is at fault. run memtest with one(each, one at a time) and also with both sticks installed, see if it doesnt just throw errors with both stics at the same time, without throwing errors with each stick one at a time. the problem is prolly in the controller, get a new mobo with ddr2 or ddr3- ddr2 is quite cheap, btw.

I think you are probably right about the controller, that was one of the first suspects I had. Cleaning would do no good since I've had the ram out so many times, if contact is an issue I just don't think it can be cleaned any better. A new board is the answer and an upgrade to my new unused dual core machine with a 64/bit operating system is over due. Luckily that ASUS board in the new machine can take a 64 bit chip.
