Thank you for the reply, I would have been in trouble. G-Skill does not even manufacture any memory for this motherboard chipsets. The MB specs says DDR2 1066, can I install DDR2 800 memory sticks? Please let me know
See if this HyerX is compatible with your board. My sticks are on water but with good air flow they should still perform well. I run mine at 1.3v, 1100 MHz slightly OCed. I cranked them up to 1100 MHz after reading an article here at Tom's which they ram stable at 1130. I plan to do some more testing.
The HYperX (KHX8500D2K2/4G) looks really really close to what the ASUS QVL (Qualified Vendor List) is saying. They were saying the "DDR2 1066 1G Kingston KHX8500D2/1G Kingston Heat-Sink Package" But I bet those were each for 1GB, I must be looking at 2GB each.
I did not check the G-Skill compatibility, so I already ordered it and it's on its way. I will not open that, return it and get the KHX8500D2K2/4G. If I am getting the 4gb, I cannot use all the memory unless I install 64 bit, can I?
The only problem you MIGHT have with the G-Skill memory is first boot. It requires 2~2.1 volts. Your system is going to try and boot with it at either 1.8 or 1.9 volts.
Start with only 1 stick, if it boots fine, which it likely will, go into your BIOS and set the voltage to 2.1 volts, shut down, insert second memory stick. If you put them in the right slots, it will run them at 1066 by default, wrong slots, it will run them at 800 by default.
Yes, 2x2gig is the optimal setup even if you do not have a 64 bit OS. You won't be able to use quite all of it, but it is still the best setup to go with for many other reasons.
