Johan, Carl,
OK if you have an OLD PSU it could be nice to put all your drives on that one just to see if it's the PSU.
Thanks for the tip. You may be on to something I had not considered. I looked into dual psu's just as a backup, but never thought I might need it to just run my system smoothly.
Just to let you know, I reconfigured how I was supplying power to the drives. I had 2 drives (1 from the sata array and the pata drive) and 2 fans all powered from the same cable. After putting the 2 fans on their own cable I was able to transfer some of the data without the machine freezing!
Is it possible to run the board with just One CPU + all RAM One CPU + one block of RAM and see how it works !! This would take load of the PSU and prove my theory of insuficiant PSU for a dual PC :) Secondly it would give some hints on how well your RAM works if you ran some memtests too. Try and pull the memtest iso image from their site and use that exclusively when doing the tests of your RAM
Now I am finding the machine still freezes seemingly depending on the size of the files (most are small files < 30k but some range from 400 mb to 5gb) so the memory could still play a factor here. I am running with only 1Gb of ram right now. Johan, how do you have the power distributed to your drives and how much ram would recommend to handle these file sizes? Also, what brand/model cabinet do you use that has space for dual psu's?
Well in the server (1:)I have the main PSU (500W) taking care of: - Motherboard - 2 sata drives - DVD - plus a couple of fans The rest is on a 400W PSU - 8 sata drives - plus the rest of the fans The coolermaster cabinet I mention before have a cute cable that help "wake up" the 2'nd PSU The RAM isn't the issue as much when you move things accross drives, but I have 1GB in in 2 of my PC's and 512MB in 2 others :) distributed like this accross them 1: 2x 512MB dual channel PC 4400 Corsair AMD 3500+ MSI board 2: 2x 512MB dual channel PC 4200 Corsair P4 2,8E ASUS board 3: 1x 512 MB (dual channel) PC 4800 OCZ AMD 3800+ DFI Lanparty Ultra-D 4: 1x 512 MB (dual channel) PC 4800 OCZ AMD 3800+ DFI Lanparty Ultra-D 3 and 4 is doing numbercrunching :) 2: is about to get ready for some testing ( OC water cooling when I get to it) All of them have 500W quality PSU's 3 x http://www.northq.com/products/powersupply/nq4775-500s.html 1 x http://www.northq.com/products/powersupply/nq4100.html OCZ.com has some cute PSU's ..... the one you have .... well to tell you the truth I'd want money to use it. For a dual CPU setup I'd pay a lot attention to PSU, actually I'd look for a redundant system that would take anything you throw at it. have you spent some time at www.2cpu.com and their forum, you should have before/during/after buying your piece :) put me on cc if you need more ideas :) Johan
Thanks,
Stuart
One can even buy a "cable/connector" solution quite cheap. I had the pleasant surprise that it came with the cabinet that I bought .... as if they knew what was going to happen :-)
What cabinet do you use. I had

Having a peak as we speak :) http://www.fsp-group.com.tw/english/1_product/0_overview.asp
it's with the 80% thing we get hit most often
General Specifications • Efficiency: 80% min., • Hold-up time: 17ms minimum at full load & nominal input voltage

I'll be happy to guide you.
I run a dual-PSU setup in my server box (bc 10 HD's & 4 x 12cm fans) If you have an old PSU it's extremely easy to do :)

This is the one: http://www.coolermaster-europe.com/index.php?LT=english&Language_s=2&url_ pl ace=product&p_serial=STC-T01&other_title=+STC-T01+CM%20Stacker
Sure it can be the RAM too
Have you check with the mainboard manual exactly how much "juice" they want / and with AMD of course
I know from experience that running a single CPU with 4-5 HD's and a single CPU + som Power hungry RAM with a 400 W PSU caused problems at big loads which happens when you move big amounts of data between two drives.

Johan,
I'd check the IDE cable too. As someone mentioned those IDE cables can be quite annoying too :)
mmmm and what brand is that PSU some of them is "pure shit" and a dual CPU system is VERY HUNGRY
