The schematic layout of the P5VDC-MX on the user manual shows that there are 4 DIMM banks, set as 2 X 2 rows, 2 DDR2 and 2 DDR.
The user manual explicity states:
I am running different frequency modules without any problems. With the info above provided by ASUS, it may be possible that a fix could be available with a BIOS update. Otherwise, you can opt to use a lower capacity RAM along with your 1GB Corsair.
Hope this helps.

Hey Wayneardo,Good to hear from you just the man I wanted to talk too..Ok tryied changing DRAM speeds to 533Mhz but to no avail..
However their is DRAM timing has a few tweaks but best not to touch this..yes?
So if ram is not reading 2 gb I am defienatley not getting 2gb..completely different to how HD can show incorrect values..yes
BTW if I had of bought the same cheap gig stick I have now I would have the same issue..yes Thanks again Wayneard.
Salute
Wayneard,yes it shows 512 on each corsair ram both the same.
Yes when both are in the read 1Gb total.
Tested frequencys cas3/trcd4/trcd4/tras12 no avail..
cas4/trcd5/trcd5tras12 no avail
cas5/3 highest setting caused the system to beep constant.Which I have not been able to return to normal..
yes I have a card gddr2 512mb.
Waynard..
How can i do a hard reset?
What you have fried my comp and will not answer me..huh ok thanks alott
Sorry Waynardo I lost it sorry..It has powered back on but i feel I should just use the one corsair gig stick and my old gig stick..so I atleat get 1.50gb
Best option you think?..Friend
No inconvenience friend..Do think it's worth changing the 533mhz to 400mhz or just leave it to auto and the ram would not be damaging mb would it should be fine. So 1 gb corsair and old ram should be fine?
Just leave on Auto. I did read that the slower of the 2 should be in slot 0 and the other in slot 1.
No problem. I would say YES, until you can upgrade your MB to one that can handle the higher performance RAM. Sorry for the inconvenience.
If you still can't get to the BIOS: Remove power cord. Press and hold the power button for 5 seconds. Remove the RAM. Remove the battery for 10 minutes. Reinstall battery. Reinstall RAM. Connect power. Power up. That should reset your BIOS.
Sorry. Still here. I can't monitor it 24/7. Any luck getting back into the BIOS?
Just want to get it straight. When you try ONE module it only shows 512 MB. Either module? And when you install both, it only shows 1GB total? Try the timing settings I posted with the Freq. set at 400Mhz. If that doesn't work, you can always go back in and set it back to AUTO. And...are you using the integrated video, or do you have a separate card? Awaiting a reply.
If that doesn't do the trick, also try a manual setting on the DRAM Timing: CAS - 3 (I believe that is the max for your BIOS. If it should have 4, set it at 4.) TRCD - 4 TRP - 4 TRAS - 12 I'll be watching for a reply. Also, have you ever updated the BIOS on this motherboard?
Sharkos, instead of 533, set the DRAM freq. to 400 Mhz. Sorry.
Hey Sharkos. Surprise! It's me! Sorry, it shoulda worked....however.... I just pulled up your motherboard manual and found this warning at the beginning of the RAM section: Due to chipset resource allocation, the system may detect less than 2 GB system memory when you installed two 1 GB DDR2 or DDR memory modules. However....there are some BIOS settings that may affect the amount. On the Advanced menu, select the DRAM Frequency and set it to the max. (533 Mhz I believe.) Try that and Comment back. BTW, your motherboard does not support Dual-channel, so using 2 different speeds/types is not an issue.
