Help problem with ram?

[zerodragunov]

I cant seem to install windows. Im trying to install windows xp but it blue screens. I used pc check(i think thats what the program is called) and it said their was a memory error. The Each stick of ram seems to work fine on their own but not together. T was told it was because the ram voltage was on automatic so i changed it to the amount provided on the stick but this still did nothing.

I have £69.99 x 1 - GeIL 4GB (2x2GB) PC2-8500C5 1066MHz Black Dragon EVO ONE DDR2 Dual Channel Kit (GE24GB1066C5DC)

Is the system overclocked right now?
You can add a little more voltage to the Northbridge to add stability and even more juice to the RAM than the sticker says.
Finally, run memtest (it's free) and see what error are you getting.
The FSB of your processor is quad-pumped, meaning that by default it's clocked 333MHz.
I don't know what the auto settings set your RAM to. On normal RAM it sets it at DDR 800MHz, i.e. well below your rated speed.
Double check RAM setting, probably best to set the ratio to 1:1 for now.

Finally, despite you PSU being more than juicy enough, it might not be giving stable voltages. Is it a single rails design, or has it got multiple rails to attain the total 750W rating? IF so you might need to rearrange how things are connected to give more juice to the mobo. You can check the voltages in the BIOS, but multimeter is more reliable in my opinion.

Last but not least, check the temperatures, perhaps the thermal paste has not been applied correctly, causing the CPU to overheat and causing instability?
What's the northbridge temp?


Furthermore, you can install Windows on just one stick of RAM, backup the disk image and do some testing in windows.
