I recently built three machines exactly the same for some friends who have their own DVD productions company.

They mainly use the machines for adbode premiere, phtoshop, after effects etc aswell as word and internet etc.

I built these just before christmas and they are having a weird problem that i cannot figure out, every so often 2 of the machines reboot automatically or the monitors go off and show digital power saving mode????

I know its not the montiors as when i try to ping the machine that stops from another machine it does respond so it has obviously crashed.

I have tested a few different things and it only seems to happen when they have multiple adobe applications open????? however i could be wrong, the strange thing is that only 2 out of the 3 machines do this and they are all exactly the same right down to the mouse and keyboard.

The specs are below but i am completly stumped here and dont know what to do next.

Abit IP35-E (Socket 775) PCI-Express DDR2 Motherboard
Antec P182 Super Midi Tower Case - No PSU (Gun Metal Black)
Sapphire ATI Radeon HD 2600 PRO 512MB DDR2 HDTV/Dual DVI (PCI-Express) - Retail
Intel Core 2 Quad Pro Q6600 "Energy Efficient SLACR 95W Edition" 2.40GHz - Retail
Pioneer DVR-212D 18x18 DVD±RW Serial ATA Dual Layer ReWriter - (Black) OEM
Western Digital Caviar SE16 500GB SATA-II 16MB Cache
Corsair HX 520W ATX2.2 Modular SLI Compliant PSU
OCZ 8GB PC2-5400C5 Dual Channel DDR2 (4 x 2GB Sticks)
Microsoft Wireless Optical Desktop 3000 Black - OEM

I would really appreciate all your help on this one guys as they need these machines ASAP.

It sounds like they're bombing out when under load. Have you overclocked them at all? Did you have to change the voltages to get 4 sticks of RAM to work?
Even if you havent it might be worth running some stress tests on them, maybe with just the cpu and then with the cpu and mem. Keeping an eye on the voltages and temperatures during these tests could give you some clues too.

PK!
 
I'd suggest increasing the voltage to the RAM as a matter of course. OcZ is ram on that motherboard can be picky. Increase the Ram votlages to 2.0 , possibly even 2.1. Also confirm the ram timings because the motherboard defaults aren't great for those ram sticks.

Fingers crossed for you.
 
id also check voltages using speed fan or another program just to make sure the psu isnt overloaded, i know that the psu is very good and shouldnt but u may have receieved 1 or 2 that didnt come out quite right :D
 
8GB RAM + possibly not fully performing PSU may be your issue. Id imaging filling 8GB with lots of Adobe stuff is a lot of strain. Maybe remove 4GB and test with that?
 
just to check guys do you increase the voltage through the bios or is there a different way as i increased the voltage to 2.0 and it is still booming out
 
justed tried 2.1 there as well and it boomed out what would be the maxium that i could increase it to
 
right guys ihave increased the ram to 2.3 asnd it is still doing it. Im not to sure about how to change the ram timings and things so if someone could let me know i will give that a go.

really appreciate your help on this one guys.

hi guys me again, i took out 4gb of ram and it seems to be working fine now i have opened all the programs and closed them a few times with no problems, were before it would have just crashed.

So what could be causing this???

I need to get it fixed for them as they would like the full 8GB of ram, lets face it who wouldnt lol.

hope you guys can help

Northbridge chipset failing under strain of 8GB RAM? The one thats working could have a slightly better fitting/working northbridge cooler. Stick a Fan on the NB of one of them and monitor the NB temps accross all 3.
 
ADDITION: Just read your spec again, and I has some major pain in the neck issues with a mates PC randomly restarting or loosing image. Found out it was somehow being caused by the Microsoft Wireless KB and Mouse. Reformatted and used a wired setup and worked fine. Just one other possibility (its always the thing you suspect the least)
 
Keep RAM voltage at 2.1, max 2.2. 2.3 is too high for my liking.

Increase NB voltage a little, put all 8GB in and do a memtest86 from boot disk on it, leave it going for 2 hours on each PC.

As said above use speedfan to monitor NB temps or if there's no NB temp on those mobos try and get your hands on a temp probe to check how hot they are getting.
