2GB Memory Upgrade

[GODz]

Good Morning All, I am new to the forums,
My Specs:

- Dell Dimension 5000
- 2 x Kingston 1GB DDR2 533MHz/PC2-4200 Non-ECC CL4 1.8V Unbuffered Dimm 240 pin
- P3 3 GHz
- 160 GB HD
- XP Home

I am trying to add 2 x 1 GB chips on my pc the Ram Chips work fine individually, but not at the same time, the mobo has 4 ram slots, all the hardware is as it was since its purchase. So far I have checked BIOS all looks well. I have reset the Bios by removing the battery.

When the 2 Ram chips are connected, it goes past the windows image but then just before it loads windows the screen goes blue and states: Parity check error, please consult your hardware manufacturer. The fact that it goes this far would suggest there is nothing wrong with the Bios or Ram Chips. Before I do a format I was wondering if anyone may have come past this issue before.

Thanks
J

Run memtest might be a good idea? What is the default voltage for these sticks, and what are they on in the BIOS?

Cheers for the response, i am not in front of my PC but i will check the MOBO voltage readings to see what it states and will get back with those. I can only assume its a default 1.8V as i have not performed any type of O/C at the moment.
