I have built the following computer that I was running XP Media Edition on perfectly but then with times-a-changing and the desire to get my hands on DX10 decided to upgrade to Vista 32bit Ultimate edition.
The problem is my ram. Since having XP installed I just had a pair of OCZ PC2 6400 1GB Dual channel Reaper Edition modules installed in ports 1 and 3 of the 4 memory bays. This is fine and works correctly as D/C. However after I have booted my system memory usage is at 56% so I thought I would increase the ram. I should add though that my 'Vista experience' rating with this config is at 5.9 on all tests.
The problem is that my mobo only supports 4GB in total and it would seem that I can't use a matched pair of Dual channel in one pair of slots and a matched pair (Or mixed pair) of single channel in the other 2 slots. Is this normal or just a sign of a naff mobo? It is an ASrock 4Core1333-eSATA2 board.
I can however use one of my D/C in port 1, the other D/C in port 2 (killing the dual channel config) and 1GB of PC2 667 single in port 3 that gives me 3GB of single channel ram. I cannot add any ram to port 4 with this config as the computer will not boot. When I get to my desktop my ram usage is at 32% but oddly (to me anyway) drops my Vista system rating to 4.8 which is a terrible loss considering the computer is noticeably 30 - 40% faster. Please some clever person answer that question for me!
Today I bought a 2GB PNY PC2 667 ram card and tried again to up it to 4GB with no luck. Again I can only get the same results as above with the 2GB PNY in slot 1 and 1 1GB D/C in port 3. Adding any other combo of ram the computer will not boot. Unless I add a 512MB PC2 667 to slot 2 then it will boot with bios reporting only 2.5GB instead of the 3.5GB installed! Don't even ask me what made me do that though as I don't have an answer!
So I am assuming that if I use my D/C OCZ in slot 1 and 3 and another pair of the same speed DC (can they be a different brand and a different speed if paired in their matching bays without affecting the other pair?) in slot 2 and 4 that it will work and give me 4GB of D/C ram.
Phew!
But if it doesn't work then that's another 70 down the pan. Another way would be to try 2 x 2GB PC2 667 D/C in slot 1 and 3 but costing 100 and leaving me with my 2 x 1GB OCZ's gathering dust in a draw.
Or should I just get a mobo that I can use all my ram on including the D/C working and configured? And any recommendations on make / model would be greatly received as I prefer this option I think, if it is one.
Just to add. I have tweaked Vista by stopping pointless processes including indexing (I don't lose files!) and the usual non MS applications.
I'm not going to disable Aero or DWM as these make Vista the beauty that it is. And I didn't think I'd be saying that 6 months ago! By the way have you noticed how all the folks that say vista is rubbish all have naff computers that can't run it!
Anyway...
Some pointers from you knowledgeable Bleeping Comp peers would be rather swell, wot. Me species-defecation is as flows...TTFN!

That motherboard does not support 2 gig sticks

No. Try not. Do... or do not. There is no try.

Thanks for that Chewy. It is working though and my ram is at 44%. Looking at that great site yoy provided a link to, I have decided to buy two pairs of the 2GB kits, Ballistix 240-pin DIMM, DDR2 PC2-8500 or here: http://www.crucial.com/uk/store/mpartspecs...4D8EDA9A5CA7304
Well thats that sorted then.
Guess I'll go mow the lawn today then and wait for the post!
Thanks

Phill.

Regarding how your score can decrease with more ram, when I built this box three years ago I tested 4 sets of low latency dual channel ram.
With only a single core cpu, my video compression bench never utilized the larger sticks but screamed with the faster ones. My cas 2.5 ballistix have served me well

No. Try not. Do... or do not. There is no try.
