Update: I found a fair deal of Asus P5Q SE motherboard that can take 4 DIMM modules and ordered that.
Now I hope the 2 Mushkin 996558 RAMs I have, the same as the one in the link below, will work perfectly with the 2 RAM modules I will order now, since I couldn't find the same modules on sale...

Unfortunately most listings don't offer information more than the memory interface, capacity, and bandwidth... I know some memories aren't compatible with Intel cpus and cas latency, timings, and voltage differences can make a problem so I asked those to the sellers together with my system information. Do you think there's more to care for while choosing the right modules in my case ?
Update 2: I just checked the Asus P5Q SE manual, here's what a related part on memory says:

I have a 775 pin modded Xeon E5450, GTX 750 ti, and 2x2GB 667 MHz RAM on my desktop.
Asrock g31m-s page says this:
- Dual Channel DDR2 memory technology
- 2 x DDR2 DIMM slots
- Supports DDR2 800/667 non-ECC, un-buffered memory
- Max. capacity of system memory: 8GB*
*Due to the operating system limitation, the actual memory size may be less than 4GB for the reservation for system usage under Windows® XP and Windows® Vista™. For Windows® XP 64-bit and Windows® Vista™ 64-bit with 64-bit CPU, there is no such limitation.

I bought 2 Hynix 4GB DDR2 800MHZ PC2-6400U, and they're not server RAMs, they're even said to work on G31 and G41 chipsets on the listing page, but they didn't boot the system, either alone or together. I took it to a service and the man said he tried another ram but that didn't work either. He also told he didn't try 667 MHz RAM and 8GB of that might work.
crucial.com shows 800 MHz RAM in lower capacities for this dektop but the only 8GB ram crucial found was 667 MHz:

I'd try 2x4GB 667 MHz RAM if I could find it in my country but I couldn't. If I buy from abroad and it doesn't work I'll waste money on shipping even if return is accepted, so I don't want to try that unless I'm sure it'll work.
I asked this at asrock.com but they didn't answer.
What do you think I shall try for a memory upgrade for this desktop ? Can it work some other 2x4GB 800 MHz RAM ?
I may also try a second hand mobo with a return warranty (I don't want to spend unnecessarily) if I can't upgrade memory on this mobo...
