1. It have 2 stick total so I removed the second one and memtest did not reported errors anymore. So I buyed a new stick to replace the defective one but I soon got another error in Windows. A new test with memtest86+ shown me that their still having error.
2. If I test the memory individually, no error. Errors only onccur when both are installed.
3. Updated BIOS and set optimized default. Did set the memory speed and timing accordingly to the manufacturer specs and their is still errors. (200 MHz 3-3-3-8)
4. I installed a fan on the chipset heatsink and also on the passivelly cooled vga card. Error now still occured but far less often. Also checked and the chipset heatsink is well fixed.
5. CPU test ok with Prime95 (Large FFTs). PSU test ok with an Antec PSU tester.
The only thing I have in mind is that it could be the RAM that is overheating (when running in dual channel, etc.) or the motherboard that is defective. Is it common for ram to overheat? Please share your experience. Thanks in advance.
The RAM : http://www.newegg.com/Product/Product.aspx?Item=N82E16820141307&cm_re=KVR400X64C3A/1G-_-20-141-307-_-Product
Motherboard : ASRock P4I65G (Intel i848/i865 chipset)
CPU : Pentium 4 3.0C
Memory : 2X Kingston ValueRAM 1GB KVR400X64C3A/1G
Graphic : AMD HD 3450 AGP passive (fan added)
PSU : The Best Power MT-500P 500W
Edit : I can't disable dual channel in the BIOS. I also tried some voltage settings for chipset and memory (low/high) with no change. Now back on default.
