Problem with new computer

[bnot]

I'll start with the most important.

Motherboard: Biostar GF81000 SE
CPU AMD 620 x4
RAM: Transcend DDR2 667mhz
PSU: Not sure on the brand ~ 450W
Hard Drive: Again not sure on the brand 250GB


I've been having some problems with a new computer of mine. Whenever I play any games I seem to have countless errors, take WoW for example. Whenever I play I will get an error along the lines of "Memory could not be read" now this could happen a few hours or a few minutes after playing. Another example is TF2, when playing I will randomly get blue screens and the same error message as WoW. I'm fairly certain this is down to the RAM but I'd like your opinions on this. Any advice would be greatly appreciated.

Right away I'll suggest you run a ramtest86. It's probably that or a psu going bad on you.

I tried Memtest, it got 4 passes in two hours. I've heard it should be ran until it completes 7 passes? But after the 4 passes I had to leave and didn't want to leave the computer on with nobody in.

Since I can't edit my post.

When I boot my computer Hardware Monitor pops up on screen. It's saying my RAM Voltage is 1.936v, and I remember reading that the maximum voltage for DDR2 should be 1.8v?

1.9V is high for anything. You msut go into your BIOS and either turn off auto voltage level or turn it on, or manually change it to a much lower value.

DDR2 667 should not require a very high voltage to be stable unless you have exceptionally tight timings.

Your RAM voltage should be set to whatever the factory recommends.I have several systems and the RAM is set to anything from 1.8 volts to 2.2 volts.

Is there anything else it could be or anything I could try before I change the voltage?

UPDATE: I just had a bluescreen and managed to write down the error code.

BAD_POOL_HEADER

STOP:0X00000019 (0X00000020, 0XE2B60CA0, OXE2B6028, 0C310201)

I would check the latency and voltage of the RAM in your BIOS.

The RAM sticks should have a sticker on it with details, sometimes stating optimised Voltage and latency. If it does not, then if you know what brand your RAM is or know where you bought it from you can likely look it up oline and find out what the optimised setting is.

I recently had trouble with my new computer where I could not even instal Windows - it would get as far as 'Starting Windows' and then freeze. Turned out my mobo was setting the RAM to 1.5V when the spec for the RAM states 1.6V. Simply changing this in my Bios allowed everything to install.

Aside from voltage, the latency can be an issue as if it is set wrong the RAM may be untable which would explain why the system is running but will then after some time crash on you.

My RAM recommended latency was 7-7-7-22, the default Bios setting was 9-9-9-24.
Make sure the Bios is set to read your RAM at its optimised latency as well as the voltage, if ths is still causing problems you may find slowing down the latency helps (I actually found after running my computer that despite the recommended 7-7-7-22 latency, it was more stable running at the more slow 9-9-9-24).
