I've got some more memory to try, but I've already changed it once. I've also looked into lm_sensors, and if I understand the output below, I've got a power supply problem - which may be the cause of the memory faults. It also looks like I've got a CPU that's running at below freezing. Anyone got any comments on this output.

In my case, lm_sensors came up with some wildly stupid results, and the documentation almost suggests that it's next to useless. You could try plugging in another PSU to see if that makes any difference. Just borrow a mate's, unscrew and unplug the box, and connect it to yours. -- Don't send private replies to my address, the mailbox is ignored. I read messages from the public lists.

I've tried all sorts of variants with different sticks in different slots, having a stick in just slot 1, having a stick in just slot 2, having both slots full etc. Every time I run memtest86+ I get errors on test 5. The location and number of the errors change as I change configs, but I never get a clean test. I also never get errors on any othe other tests, just test 5. What's the chance that the problem's something other than memory. Any ideas what I can try next? -- Gary Stainburn This email does not contain private or confidential material as it may be snooped on by interested government parties for unknown and undisclosed purposes - Regulation of Investigatory Powers Act, 2000

Since you have repeatedly tried different dimms, with changing location results on test 5, I would assume this is likely a power supply problem. The other choice is the motherboard. Try one at a time and you will eventually find the culprit.

Most of the time the PC will work fine, but occasionally it'll have some unexplained error. You think it's just a programming fault, but once you swap the RAM, the box becomes 99.99999% reliable. All I can guess is that the fault exists in some part of the RAM that's either not used often, or is usually gobbled up by something that does nothing most of the time. The only time a PC is 100% reliable is when it's unpowered. You can tell, with absolutely precision, what it will do. -- Don't send private replies to my address, the mailbox is ignored.
