At this point we need all the help we can get

Interesting about this "max memory" setting. I don't think any of my systems have it.

SS

sometimes its called installation configuration. It narrows your options to make installation run more smoothly

Dont mean to jump in here but does your bios have a setting for max memory? whats it set at?

It does not have a max memory setting; the manual shows that the max supported memory for this board is 16 GB (4x4GB)

Do you have a 32 Bit or a 64 Bit OS.

Please check that out.

I have 64-bit version of Windows 7 :)

Enable memory remapping in BIOS.

I tried, but to no avail... my job is keeping me from going back to the shop for now so no other news yet. I'll try this again tomorrow maybe I messed up somehow...

Okay an update on this one I got some new memory from the shop. This set is LISTED on the compatible memory list, but still no dice on the dual channel (same results as before, but now with kingston dimms).

Also I was actually able to update my BIOS oh, and right after I did that I found out why I couldn't update it before. Instant flash only supports reading the flash file from FAT16 and FAT32. And my usb pendrive as well as all my hard drives are NTFS formatted. (yes: dot dot dot) Luckily ASRock released a windows update utility type thing for their latest BIOS ROM, so that worked just fine.

I sent an e-mail to the ASRock support of whom I expect as much as... well ... bugger all. If I ever get a reply and if it's mildly entertaining or if it solves my problem I'll post it in here.

Not to but in, but i have a similar problem.

I have Windows 7 Ultimate 32bit running on, lets say an aged computer and have 2GB (2x1GB) of DDR ram installed on the motherboard but Windows is only recognizing 1GB. Only a few days ago it still registered 2GB.

I have switched the sticks in the banks, tried a few different working 1GB sticks, and nothing changed. I downloaded speccy and it says i have the full 2GB installed but Windows is still only recognizing 1GB. I don't have any video cards, standard on-board adapter with 64MB shared memory. The most recent thing i've done is install a PCI 4-port USB hub and a 4 port USB front panel controller attached to the PCI hub.

Any ideas?

Hey I don't think the answer I got will be of too much use to you (or at least not what you want to hear), I actually bought a new mobo (gigabyte) and with the same DIMMs it all went as expected. The ASRock mobo I had (P55 pro) is apparently really bad as I've seen numerous complaints about it all over the net. The deluxe version or the extreme version both work like a dream according to most, the pro is just not all that great.

I'm not sure what the full story is with the motherboard, but I think a chip on there doesn't work as well as it should and the windows drivers are unable to address the memory even if the memory in itself is fine.

In general if something "suddenly" stops working and a clean Windows installation (or maybe linux?) doesn't help there's a high chance that it's a hardware related issue.
