can a motherboard get too cold?

[ny_driver]

Or maybe a PSU...................

I had my system all set up out on the back porch, under cover but outdoors, and once it got really cold after about an hour of being out there running it started having random shutdowns. And by shutdown I mean like it was unplugged. It would power back on if I hit the button and shut down again after a few seconds.

It's been back inside running normally for almost an hour now.

Strange or no? It was -1C on the back porch.

[Patch]

Yes, mobo's will absolutely cold bug.

-1C seems pretty warm for that be happening, though.

[Chuchnit]

Temps that low is hard on hdd's too. You might want to find a way to keep your HDD a little warm while doing the outdoors stuff.

[ny_driver]

Something was definitely bugging out and causing the power to cut out. The board overclocks like a bastard indoors. I just popped in my new Opteron 154 and cranked it to 3400+MHz on only 1.55v. I am quite impressed with the chip.

[Chuchnit]

Well what you are describing isn't due to the HDD's. I was just trying to give you words of warning that too cold of temps = really bad on HDD's. You could have just CB'd the board or something else.

[Kal-EL]

Are you running off an extensioin cord or sumtin?
But yah, you can cb a board for sure.

[ny_driver]

I was running off a probably inadequate extension cord....the system and the monitor.:blush: I didn't have a problem with that before though.

I put the board out there to pre chill for awhile before I hooked anything up, and it ran fine for about an hour maybe less.

[ny_driver]

:) I'm pleased to announce I just churned out the #2 all time overclock on the DFI LP UT nF4 SLI-DR. (http://hwbot.org/community/submission/1090323_ny_driver_cpu_z_opteron_154_90nm_3454.2_mh z)

When is the bot going to update their list and give me my 8.5? Usually that happens immediately.

[Hondacity]

usually they are slow lol, but it will eventually work

[ny_driver]

How come I didn't get any points? I got 1 point for #3 cpu overclock, but I got 0 points for #2 motherboard overclock. That's bullshit.
2d rankings SLI-DR (http://hwbot.org/hardware/motherboard/lanparty_ut_nf4_sli_dr?tab=2drankings)

[Hondacity]

mobo oc doesn't get points. it would be nice to get points for it though.

[ny_driver]

So the general consensus says that the mobo must be cold bugged. Correct?

I think I'll try setting up in the garage today where it's not quite so cold. I hated seeing my new baby running @ 40+C last night. :scared:

EDIT: I got smart for minute.............I set the board and PSU up inside a 6" deep clear rubbermaid container, so I can move it around more easily when it bugs out again. I may use the heatgun if necessary.

[Patch]

Fun stuff going on there ny. Keep it up.

[ny_driver]

You bet, brother. :D

[ny_driver]

Update guys: I don't think it was the board. I put a coffee cup warmer under the HD, which keeps in up ~22C....thing ran great!!!....I was out there about an hour or so KILLING superpi(25.2sec), I can't wait to submit that score. :cool3:

Then I went for max overclock again @ 1.63v and was astounded at the difference a nice cold NY day can make. I'm going to validate 3.6GHz before the day is done. :taunt:

pics :P

[ny_driver]

They're coming I had to brag first. :blush: here's a picture for ya (http://hwbot.org/hardware/motherboard/lanparty_ut_nf4_sli_dr?tab=2drankings).

[Neuromancer]

Glad you got it sorted :)

[ny_driver]

New problem with the board. When I increased the vcore to 126% and saved and went to boot up it just shut down. Now it powers for a split second when I push the button and shuts right back off.

What does this mean? I guess the board could be CB even though I think the HD was the problem before. I'm freezing the cpu socket now.

Help please.

[Kal-EL]

Either the board is crapping out or the psu went to shit the bed. Keep tinkering till you find out which one...

[Hondacity]

is this with dice?

old motherboards apply the voltage set from the bios....instantly from the boot

sometimes this is helpful..but sometimes it hurts the boot.

[ny_driver]

Not dice yet, just the chiller I built. I can try another PSU quick I guess. Thanks for the idea. I don't really suspect my Corsair TX850, but I guess I can hope since it's guaranteed.

[DOM]

overclocking in a box :D

only time i had a mb shut off when powered it up was water in the socket lol

does you psu have a light on it ? mine has one think its orange when off, green when on, red when theres a short....

[ny_driver]

I tried a different PSU, and the symptoms changed to the 4 LEDS of death....is what I heard it called earlier.

Strange.........hmmmmm......I better test that PSU out tomorrow since this is the 2nd odd fatality that was connected to it. :keeporder:

[Neuromancer]

I thought it was PSU related earlier. Build a chamber for psu and hdds and keep them in the 60F+ range. coffe cup warmer with a heatsink on it and fan should do it :)

Worth a shot... all it wastes is TIM

[ny_driver]

I thought it was HD related earlier, but now I think maybe it was actually the board having a minor heart attack when it was cutting out Monday. PSU doesn't seems to mind the cold.

Why can't I find information about the LEDS on these LP UT nF4 boards?

[ny_driver]

Update guys: I don't think it was the board. I put a coffee cup warmer under the HD, which keeps in up ~22C....thing ran great!!!....I was out there about an hour or so KILLING superpi(25.2sec), I can't wait to submit that score. :cool3:

I got 3.74Ghz and much better superpi.

[Mr.Scott]

Why can't I find information about the LEDS on these LP UT nF4 boards?

Because the real DFI Street no longer exists. You have to rely on info from former members.;)

[ny_driver]

It's a good thing I know people.;)

[ny_driver]

Strange.........hmmmmm......I better test that PSU out tomorrow since this is the 2nd odd fatality that was connected to it. :keeporder:


Sure enough I didn't test out the PSU today.

I tested 2 boards out though with my old Enermax and they worked fine. So I picked a board and installed it on my main bench with the chiller and the Corsair TX850. Well what do you think happened when I hit the power button? It powers for a split second then shuts off same as last night after it quit and I thought it was the board.

So I hook the Enermax to it and try it and of course I get the 4 LEDS of death. I'm going to put another board on the chiller bench with the Enermax and see how that goes.

I'd have to say my fancy shmancy Corsair is junk. I'll test it out later, but I'm not hooking it to any more boards to do it. I'm sure Corsair will replace it, but I'm sure they won't do anything to cover the 3 boards I say were killed by it. I'll try like hell for a upgraded replacement at least.

Not happy.

[ny_driver]

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. :shock: 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.

[ny_driver]

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.:Dizzy:

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.

[ny_driver]

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

[Mr.Scott]

I have no idea what you're doing to kill them.:Dizzy:
Right off the top of my head I'd say condensation, or CB.

[ny_driver]

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]

See post #2.

[ny_driver]

Right but that wouldn't kill it would it?

[Mr.Scott]

Right but that wouldn't kill it would it?
No idea......but you never know.

[ny_driver]

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

[ny_driver]

:ohcrap: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?.

[ny_driver]

DEAD CPU causes the 4LEDS of death. All the boards work fine with a different cpu except the very first one I bricked.

It's a good day I guess, except that was the best cpu. Going to try a 152 and see how it performs next week.(actually bought 2 due to a bad addiction I now have)

So now I have only 1 dead Ultra-D, 3 Ultra-Ds, 1 SLI-DR, and an Expert on the way instead of 5 dead boards and an Expert on the way that I'm scared to even try out.

The cpu just shit it's pants when I set it to 1.8v up from 1.73v. Seems strange to me.
