BRRRRR Too Cold

[runmc]

I bought a AMD A64 -3200 to use to test mountings on my cascades. Well it didn't like the cold. I booted to desktop before the evaporator got sub-zero and all was well. When my processor got below zero I got a blue warning screen.

Does the 3500 do better with sub-zero? Do any of the A64 939s do well in the cold? I would like to take this 3200 and trade it in for something that will work. I'm planning on a fx55, so I don't want to spend awhole lot more money.
thanks

edit - 3500 - socket939

[Kunaak]

is your 3200 a 939?

if it is, chances are you just got a winchester, and well... theres just not much you can do about it, they just don't like the cold all that much usually.

you can either look for a newcastle 939, a 754 CPU, or a FX... oh yeah, or a 4000.
those are about the only CPU's that work without much hassle for sub zero.

winnies of weeks above a certain point dont have the cold bug:




Never mind the pi time or clocks.

Im not sure if they will work @ -130C but thats yet to be tested

[runmc]

Thank you guys

The processor I have is a socket 939 - 3200. Do the 3500 or 3800 (socket 939) do okay with the extreme cold? That's as much money as I want to spend.

The 3800+ should be fine, the 3500+ should be ok IF it is 130nm Newcastle core, not 90nm Winchester

ive seen some winnies not have the cold bug, try to find or buy one off someone like that, they clock better than castles and are a little faster clock for clock. Maybe you can also snag a fx53 pretty "cheap" especially since the 90nm fx55s are about to come. Whats your budget limit? I recon you can snag a fx53 for $450-500 or so. If you can wait a week or two, there will be san diago in fx55 and 4000+ flavors(March)
However, let it be known an air cooled fx55 goes almost what a phase change fx53 does

[runmc]

Great answers!!! I will trade the 3200 in on a 3500 NewCastle today, and wait for the 90nm FX55s to come out and get one of those.

GeForce ti4200 - Jason5757 has been telling me about the 90nm 55s. Do you have any more specific information about them and on the market dates?

in green font, it says fx55 san diago and the month of March. I also see resellers say they are expecting new shipments either the end of feb or beggining of March so this is 2 weeks from now However be prepared to pony serious cash, could cost $999 theres also a 4000+ that may be much more tolerable to your budget. You could always just stick with your 3500+ newcastle if you dont mind an air cooled fx55 being faster than your chilled 3500+ castle

I traded the 3200 in on a 3800 LMAO. The NewCastle works fine with sub-zero,but OMG, it is a terrible overclocker. Maybe I'll take it back and exchange it for a FX53 when I get my allowance next week.

[__TRONIK__]

My 3200+ winnie does great on an old Mach I, and a really junky refurb neo2. 3ghz is rock stable, and I am expecting more wehn it goes in the dfi nf4 this week. I don't think the bug is in the chips. I think it is in the boards. It took some effort to beat the bug on this neo and the previous one (that I killed) but it has been kosher since, and my temps are -15c idle and -5c load on-die via probe. dont pay much attention to pi socre, this board only lets me do ddr400

Hey _Tronik_,

Your post begs the question... How did you beat the bug?

I have tried two Winchesters and both wouldn't go with a LightSpeed on a MSI Neo2.

3800+ castles are rare and expensive, a fx53 would be a much better deal. hows that 3800 clock anyway?

The 3800 castles won't clock for nothin. As a matter of fact it won't even boot past Windows logo now. I think I froze it. It will post to the logo but reboots righ before going to desktop. I took the cascade off and put the stock fan on it and it still does the same. I'll let it sit over night and try it again tomorrow. It doesn't look wet, but it's been raining here in the Dallas - Ft.Worth area last night and some today so it's high humidity. It's gonna be humid here next weekend it looks like. They are forecasting rain Wed and Thursday so far.

[Formann]

MOBO issue maybe?

None of the Winnies i have tried have problems below zero.

0445
0447
0450

All running just fine in my MSI Neo2 week 0411 (Korea)

Maybe its just not cold enough? In using a custom cooler Overklokk built for me. -44c load 1.8v 2900Mhz

What temp did you hawe on the evap on tihs CPU?

[__TRONIK__]

for those wondering, I am 99% sure it is a board issue. I saw the same well known behavior on my winnie across two different neo2's, with same winnie. I could sit in bios menu all day, but windows would restart after a short time. The fix for me was this. Prepare a boot cd with beta 136beta and the 15x bios. wait until everything has been off for a bit, like till next morning. Boot up, immediately flash to 15x, reboot, go into bios and reboot again. next boot flash to 136beta, reboot, go into bios, reboot again, flash to 15x again.

so flash 15x, then 136beta (almost any probably works) then 15x again. flashing 15x never worked for me alone, I totally stumbled on this but it works. no restarts, no nothing and I have been running 3ghz 24/7 for weeks now, occaisonally I reboot voluntarily for a windows update or something, no problems at all.

have observed this on first mobo, 0440 neo2 (which I killed) and then a refurb neo2 from 0420. same 0441 3200+ winnie.

did NOT notice any problems in brief run on epox board. Don't expect any when I put it on the DFI this week.

[berkut]

Its not all about a mobo issue.

When i tested the neo2 + winnie 3000 with various bioses none of them changed the situation with the cold bug. stock, modded etc. none of them changed anything but overclockability.

All of them hanged when i entered the temp monitors in bios showing 40C or sometimes 255C (im not 100% sure on this but it was a large number). In windows hardware monitoring the temp was a constant 40C. Once the temps go below 0C, pah 40C on the monitor.

What about my three winnies? They all run just fine.

I got the Neo2 0411 (November) batch because I read somewhere that this does not have the cold bug. From the first time i booted this Neo2 it would run all CPUs I have tried without a hitch. The BIOS shows 40c all the time, but its running just fine.


Go get a november batch.. or later. Then youll see

[Zyklon5]

Berkut ... above what week ?

And what do you mean by cold ... LN2 cold or cascade/VapoChill kind of cold ?

[berkut]

below 0C

[runmc]

What temp did you hawe on the evap on tihs CPU?

Let me explain my situation.

DFI NF4 with 3200 winnie @ -100c evaporator did nothing. I had the 3200 at desktop and I turned the second stage of the cascade on, as soon as the temp dropped below 0c (somewhere right around there) system rebooted, and kept rebooting.
DFI NF4 with 3800 Castle ran fine at -100c for sometime (a couple of hours ) but then started rebooting. It started rebooting when I shut the mobo off to change hdds. After the pause the system would reboot right before desktop after Win logo. I think something got wet (that's my guess) I'm gonna give it another try today.I did take the cascade off and put stock hs back on and still got reboots.
I believe the 3200 winnie was definately the cold bug... and not the mobo.

Hey __TRONIK__,

Your's is at least something to try!

I wish I had known of this earlier. I was using 1.36 and tried the dreaded 1.52 which hosed my motherboard. I've returned the board and cpu. I'm in the market for replacements.

I wonder if reflashing 1.5x a couple times would do the same thing. And I wonder what it's doing.

It would be great if someone else could confirm.

You're the first person I have run into who had the problem, flashed to 1.5x and fixed it. Everyone else either can't get it to work, or can't get the problem .

Karl

[__TRONIK__]

okay, no one's experence is all that surprising to me, and I am still not convinced it is not jsut a mobo issue. first I can not speak to any experience apart from Neo2, so if you runsomething else, my advice doesn't apply.

I can't go into the bios hardware monitor page either, at least for more than a second, in and out, otherwise it goes to 255c and hangs. this has not changed.

before you say it does not work, attempt the triple flash method.

and RUNMC, man, sweet problem to have! you got a cascade? you seem to be running into an alltogether different problem - your winnie being too cold. evaps that cold have caused many problems for people with winnies that have had them run fine at subzero. unlike NC's and CH's winnies do have problems at that temp, and I think there is nothing that can be done about that thusfar.

people are making the switch to DFI en masse right now, mostly from neo around here - advise to check with some of those people and see what they are experiencing with frozen winnies. I myself will be able to tell you by this time next week.

don't give up, my friends. I was ready to toss this combo in the dumpster (figuratively) but very glad I did not.

[runmc]

beat the bug on my neo...
stable at 3ghz on winnie and testing for more

It's very cool that you beat the bug!! Although I did trade my 3200 winnie in on the 3800 Castles, I did notice ZipZoomFly is running the 3200 at a decent price. I might just pick up one and see if I can beat the bug using you tripple flash method. The winnie is a really nice cheap overclocker. Kinda like the 1.6a Intel chip from a few years back

thanks for your inputs...
