Faulty PSU or motherboard?

[mashie]

Hello, I just assembled my new computer from parts I got from OcUK. First let me list all the parts used:

ATI Radeon X1900 ***Crossfire Edition*** 512MB GDDR3 TV-Out/Dual DVI (PCI-Express) - Retail (GX-045-CO)
HIS Excalibur ATI Radeon X1900 XT-X 512MB GDDR3 AVIVO TV-Out/Dual DVI (PCI-Express) - Retail (GX-047-HT)
Western Digital Raptor 150GB WD1500ADFD 10,000RPM SATA 16MB Cache - OEM (HD-069-WD)
FSP Sparkle FX700-GLN Epsilon 700W ATX2.0 PSU (CA-001-SK)
Liteon SHM-165P6S-09C 16x DVD±RW/RAM (Black) - OEM (CD-048-LO)
Mushkin 2GB DDR XP4000 Redline Extreme Performance Dual Channel Kit (2x1GB) (991493) (MY-002-MK)
AMD Opteron UP 180 Dual Core San Diego 2.4GHz 2MB Cache (Socket 939) - Retail (CP-154-AM)
Asus A8R32-MVP Deluxe Crossfire (Socket 939) PCI-Express Motherboard (MB-131-AS)

All is installed in a LianLi PC-777B and connected to a Dell 30" (not bought at OcUK btw and working just fine on a different PC).

Now the problem, when booting up the PC I have only managed to get the system to boot at all about 6 times, twice with the full setup, twice only running the Master Cards and twice running the XTX. In between I have had 50+ attempts between the various configurations where the screen stay black, no beeps and no attempt to read any media (HDD nor CD). The limited faultfinidng I have been able to do is mainly entering BIOS where I have noticed the +5v is at 4.9v, all other voltages seems correct. All AI overclocking stuff is disabled.

During one of the successful boots I tried to install XP but it died horribly with a BSOD after 10 min while formating the HDD.

Also when it booted I could hear a beep in the speaker so it is plugged in correctly, after that I have never heard it again.

Soo, which parts do you suggest I RMA to get this £3500 pile running? PSU, motherboard or both?

Unfortunately the manual has no entry for "no beep" which is the occurance when th esystem doesn't boot. All that happens then is that the fans and the HDD spin up.

As for the power rails, I would be really surprised if any were overloaded with only mobo, one videocard, hdd and cdrom installed considering each have dedicated lines out of the PSU.

I will test using a single memorystick as well when I'm back home after work.

Could be a faulty board, my mates just returned his Asus due to it being DOA, the led's would light fine, but the CPU fan would just jerk, then nowt, and it looks like another faulty one in the motherboard section, as there someone in there with what looks to be a faulty board to, starting to look like a faulty batch to me.

Thanks, good news, will try and RMA the board first then.

I have solved the boot up problem now, it was one of the Mushkin sticks that was dead.

 

[mashie]

ahh well least one of my sugestions was right

Indeed, however the box isn't stable yet though. When I play EVE-Online I can have three clients running in 1920x1200 windows just fine for hours, however if I decide to run a client at fullscreen 2560x1600 it will spontaneous reboot after 3-4 min.

I will need to gt a few more games running to see if this is a software or hardware problem.

I'm running on two 512MB Corsair PC3200 LL sticks at the moment btw.

Quality, I returned the Muskin memory yesterday and I must admit that they did deal with it quickly, maybe too quick considering I will receive a PSU tomorrow...



So now I will have two PSUs and no memory, hooray.

 

[mashie]

i had to rma my mushkin aswell , also was one dead stick although it didnt beep just wouldnt boot , anyways got two different sticks and been ok since

Lol, I wonder if I got your old sticks then...

 

[mashie]

Allright, I just got the parcel and I was surprised it actually contained the Mushkin sticks and not the PSU as stated in all the paperwork.

Can't wait to test it out after work.

So apparently the webnote system works but it can be really confusing.

Hi , good news then Are you oc ing , if so can you post how high you get that redline and what timings ect
Thanks andyr

Well, I got the same sticks back as I RMA'd, one of them has received a red tick from a pen so I guess they figured out which was broken though...

Just pure luck I have a spare set of mem here so I at least can run the box until thi smess is sorted.

 

[mashie]

Well just thought I should put in a little update here. The RAM is back with OcUK again so hopefully I should get some working sticks soonish.

At the moment I only have performance numbers for EVE-online:
2560x1600 12xAA 16xAF at around 100 fps.
With vsync on it stay nicely at 59-60fps.
