Hi guys this is my first post here so here goes....

My current rig is a:

EPoX EP-8K9A2+ (Socket A)
AthlonXP 3000+
GeForce7800GS
2x512MB Corsair XMS3200C2PT Platinum CAS2

I've just recently ordered an ASRock939Dual and an Athlon64 3700+ San Diego. Will my current RAM work in the ASRock or will I have to buy new 'Dual Channel' memory? Im hoping I dont have to buy new memory cos i cant afford it right now :? Help appreciated Thanks!

The one on the download page may be newer than mine here and may have a QVL.

The only thing about the DualSATA2 is it only has 2.5v(normal) or 2.7v Vdimm (high.) Thats plenty for PC3200.

My first post too, but I have some info. I have three rigs up and running around the house and one of them is using this board. I have two 512mb dimms running in dual channel mode, so you should be okay.

From what I understand, as long as the mobo supports dual channel mode, all you need is two identical sticks of memory. The part that seems to come under scrutiny is the "identical" part. Some mobo's are quirky and won't recognize two apparently identical sticks of memory. Other mobo's run in dual channel mode with a wider array of memory choices, but they still have to basically be the same, i.e. memory on each stick and speed rating (DDR 400, etc). You should be fine with what you have. Good luck! My board is working just fine, great to have the flexibility of AGP and PCI-E.

Hmm ive just noticed that one of the corsair sticks is actually XMS3500 :? not 3200. Will this mean they wont work in dual channel only single channel?

The memory I have is:

1x512MB Corsair XMS3200C2PT Platinum CAS2
1x512MB Corsair XMS3500C2PT Platinum CAS2

Thats correct as of now lol.

Ok im up and running very smoothly. I had a terrible time getting my GeForce7800GS working! The drivers wouldnt install properly. The ForceWare installer would attempt to install the drivers and the monitor would flicker a few times (as if its cycling through different display resolutions) and the system would reboot. I fixed this by ENABLING something called 'Fifo' in the chipset BIOS settings. I cant fully remember what its called and what its for but the description said something about recommending it being enabled for NVIDIA bridged AGP cards. The RAM is also running in dual channel mode which im happy about.

EDIT: Just checked the BIOS. Its called "AGP P2P Deep Fifo" - "For bridged Nvidia AGP card, please set to enabled". I dont know what this setting actually does but it fixed the problem.
