can a motherboard get too cold? - Page 4

I went ahead and installed yet another Ultra-D on the bench, I hooked it to the Enermax that powered it perfectly during initial testing. Booted right up to XP np when I tested it.

Anyways I spend an hour hooking everything up perfectly and the board is dead now....4LEDS of death.

I'm getting really sick of that term. I don't know what the fuck is going on, but it's getting a little tiresome.

What should I do?

I'm going to test the 2 PSUs out with a meter... but, all the voltages look good in HWMonitor and the BIOS with both of them....I check that all the time.

PSUs both test out very well under zero load. 12v was 12 or 12.2, 5v was all 5s, an 3.3v was all 3.4v.......on both PSUs. Old ass Enermax EG701AX-VE, and Corsair TX850.

The board is always fully screwed down, but gently of course, to a removable mobo tray that came out of a case. That is screwed to a plywood base. I don't see how there could be a grounding issue.

The boards worked perfectly screwed to another tray that I took out of another case and sitting on a stool.

It's sure got me thinking.

Maybe these boards were all just ready to die, or perhaps the cold weather transport? They both booted right up and went to BIOS then Windows np at all.

Yes I'm beating this horse to death here, but I really want to play some more and I'm scared to hook up another old LP board. I'm afraid I'll break it and then I will be mad as hell.

Next up is the brand new looking with nothing opened, and a perfect box, obviously hardly used Ultra-D, that I didn't even want to take out of the box. The guy tested it before he shipped it since it had been in storage awhile so I believe it works.

I'll grow the hair to try again while I sleep I'm sure.

So was this all too much reading, or is it just too odd and unexplainable?

I have no idea what you're doing to kill them.

Right off the top of my head I'd say condensation, or CB.

ny_driver · #35 12-16-2010

Definitely not condensation. I was indoors, and although I had them hooked to the chiller at the time of death, I hadn't even turned it on yet for either one of them. I always let the chip/block warm up a little after first installation before first turning the chiller on to let the TIM spread out. I seal the chip in for short term with kneaded eraser, long term Dragon Skin...some paper towel gaskets, and some tight insulation. I've had no condensation problems since building this device.

I have a board installed now, but I'm honestly scared to turn it on. This one is mint...got it from the owner/operator of Rebels Haven Forums. I'd really hate to kill this one. I decided not to pre-test it prior to installation, as that hasn't been working out very well lately.

I don't know I just hope this one works like it should and doesn't have a heart attack and die like the other ones.

EDIT: CB(cold bug)? What exactly do you mean to say about CB?

Mr.Scott · #36 12-16-2010

See post #2.

Right but that wouldn't kill it would it?

No idea......but you never know.

So I fired it up and all I get is 4LEDS and the fan.

ny_driver · #40 12-16-2010

I think that 4LEDS may indicate that the Opteron 154 has died because it works with the FX-55 in it. Maybe it needs BIOS update to support a single core Opteron?

Or could I have killed the Opty by attempting to increase the vcore from 1.73 to 1.8v?.
