Check compatibility for DDR2 4GB RAM.
Check compatibility for DDR2 4GB RAM.
Hello everyone, welcome! I'm reaching out for some guidance. I recently upgraded my older PC with 4x4GB of DDR2 RAM (Samsung 4GB 2Rx8 PC2-6400U-666-12-E3). My motherboard is ASUS P5Q, and according to QVL it should work with this RAM. However, I'm still having issues—Windows won't boot properly. The BIOS lists 16GB of RAM, but when I try to load Windows it keeps showing random BSODs. I've run MemTest and TestLOOK, but the results are inconsistent (beeps on 23% of tries) and it seems to work with other RAM modules. I've also tried different RAM slots on my AMD motherboards, but everything functions correctly there. Can anyone help me figure out what's going on?
Thanks for your input. I reviewed the MemTest results. All four tested units performed well, even with 4x2GB of Samsung RAM. The issue you're noticing might be related to the testing process or software behavior. Regarding the Samsung Zhidian, it's a mid-range smartphone from Samsung, known for its performance and battery life.
Do you possess a 32-bit version of Windows? Machines equipped with DDR2 memory typically came with 32-bit versions since they didn't require as much RAM as modern systems. A 32-bit setup cannot handle more than 4GB of RAM, so ensure you have a 64-bit copy. Edited July 12, 2016 by InitializingDev
Hey, I'm having trouble getting into Windows. I don't have x86 or 32-bit version (I use x64 Windows 10). From what I've mentioned, the BIOS can recognize 16GB. It seems like the issue might be related to the memory configuration or something I'm not handling well. I've increased the CPU's FSB speed to 400, which should work at 3.4GHz without extra cooling. The voltage and temperatures are around 35°C. It's a Core 2 Quad Q9550 chip.
Occasionally when switching hardware, Windows might not cooperate. It could be due to a corrupted installation. I suggest using an old hard drive if available and installing a fresh copy (no worries about the key—30 days of free installation). If you lack a drive, a USB flash drive can work but results vary. Running a boot test confirms the system is functional and not hardware-related. Likely, it’s just a Windows issue rather than a physical fault.
