I received one of Jinu's V2000 Systems and installed my asus M2N32-SLI Deluxe and FX-62 Processor I haven't installed my drives yet or my watercooled video cards but i put a test video card in the system and it post fine and i go into the bios screen fine but then as the cpu temp drops -33c the system freeze's every time. Is this the cold bug? If so is there a way i can tell the g-froster to keep the evap temp at a higher temp? does it have a thermostat? I only get about 2 mins before the system temp drops to the point that the system hangs. I guess i could raise the voltage of the cpu and put a quick overclock setting in bios before my 2 mins is up and save settings and reboot, hoping that the increased cpu temp will keep it warm enough??? if so what is the maximum safe vcore voltage of the socket am-2 fx-62 processor? Anyone else have any ideas? Ive got to install an OS and i dont think installing an os is going to work the cpu working enough to keep the temp up so the system dosent lock up.
Thanks a Ton for any help you guys can Provide

not sure about how to stop it, but thats cold bug alright, and theres not really anything the g-froster can do about it, I do have one a fix for you though: Sell the FX and asus for cheap to someone who doesn't like cold, buy a conroe ES and PCH-DL or BadAxe. You will be much happier in the end :D

Definitely coldbugged cpu. Oppainter mentioned in the AMD thread that his coldbugged at -40c, he ended up using a -30c waterchiller to bench his fx-62. Kingpin also had to use a waterchiller to bench his fx-62 with -10 to -15c temps. I'm not sure how to fix the problem. I'm pretty sure even if you did raise the voltages, the problem will most likely be there. Not sure if you're able to return your items, but the best bet would to be to go with conroe like MeltedDuron stated. The coldbug is extremely rare to non-existent with single phase units with intel.

Lee... Want copper plate to sandwich in between so that temperature might not hit that low? I am making some of them in few days... to see if it helps some customers hoping for bit warmer core temperature.

Yes Jinu please send me one, let me know what i owe you and ill paypal it to you. There must be a big difference between the system you built and the prometeia Mach II i have because my fx-57 cpu temps never gets anywhere near -33c :). Guys i will buy a conroe but im kind of waiting for the nvidia chipset motherboards to be released, i just bought 2 7900gtx's and dont want to give up sli.. i figure that nvidia will make a better sli chipset than intel but i could be wrong. but thanks for help
Jinu let me know about that metal plate in the mean time
Thanks

was going to suggest copper plate sandwich thats nice of you helping your customers like that jin :) There is a huge difference between a mach II and anything Jinu would build, because the prommy's use crappy gas that doesn't get cold enough, I think smaller compressors, and they have utterly awful evaps/mounting

Mach I/II compressors are fine! But Sealstring :nono: :nono: :slapass:

yes mach I/II uses Danfoss NF9FX unlike vapo LS (NF5.5CLX)
basically, the improvement that can be done in mach II is primarily in evap design and tuning while on vapo LS, it is compressor. About same thing really in each end :)

didn't say anything about compressors, the mach 1/2 use lovely compressors, they are just crippled with a refrigerant barely fit for air dusters and an evap i wouldn't cool my nuts with :rolleyes:

just use some app to keep ure proc 100% loaded (rosetta,boinc,prime, etc) that should keep temps higher, and with a bit a luck high enough for ure coldbug..

What size copper plate are we speaking of ? I have a few 2" X 2" X 1/4" already made-up.
If that is what your needing jinu, I could send it for you.

There is no way to reglute temperatures in a SS by a controller, unless the use of an electronic valve instead of the cap tube.

Ssilencer is there a way to change the temp at which the controller starts the computer? its currently set to -25c. If i could set it to -5c or something i could buy myself the time i need to get the cpu loaded (maybe) :)

RunMC are the copper spacers you have slightly smaller than the ihs on a amd processor? (I just read that they are 2 x 2 but i could cut it down myself if its only a 1/4" thick.) if so i will paypal you money to overnight me one???? Plus something for your time i know its a pain in the ass to box stuff up make a label and go to fedex. Ive been to homedepot and didnt find anything that fit the bill as a spacer.

Jinu even if RunMC sends me a spacer please make me one and ship it when you make the others for your other customers and let me know what i owe you.

Guys THANKS A TON! for all your help and suggestions.

Thanks Lee

sorry about your chip. I have used 2 AMD chips. One was a winchester not cold bugged. The other (actually) is a X2 4200 bugged at -40C only at start up. So I boot at -33C and have no problems....

Sure, install the soft and set the start at the temp you want, just be sure to change the shut down temp to higher point :P

Well, technically you can semi-change it by controlling condensor fan speed, but it's nowhere near accurate enough to be considered temperature regulation.

Thanks ssilencer i put a drive and floppy and cdrom in it... i didnt take apart my fx-57 and mach II, i just went to the office and got a cheapo WD 80GB SATA drive, floppy and combo drive and installed them, i made a really nice foam for front and back of motherboard and used the factory back plate then i remounted everything in the case. While i had it out of the case i installed the factory mount and amd heatsink/fan combo and booted the MB up and overclocked to 3150mhz with 1.550v vcore (hoping to keep the temp up). Now i have everything back together and im going to try to boot up and do an OS load... i dont really hold out much hope untill i get rummc or jinu to send me a cooper shim plate ... (note to runmc or jinu ill let you sleep with my wifes sister if you send me a shim plate :) ) Anyhow im going to try an os load if i get that far ill load your software and raise the start temp. and the shutdown temp.

Question?.... why cant you make a SS with a thermostat??? I know im an idiot but my refridgerator has a thermostat:) and it would be nice to be able to dial a evap temp that you wanted...
Thanks and sorry for all the long post

i took a koolance chipset waterblock and made a spacer here are some photos. it measures 1.5" x 1.5" and 3/16' thick. I had to grind and sand on one side for an hour or so to remove all the barbs so its not as smooth as a lot of the work i see on this site but the whole purpose is to raise core temp right :) I hope this will keep the coldbug from locking up my system.
Ill let you know

Because a thermostat just shutt down/start up your unit, you can do that in a freezer or in your refrigerator, but if you shutt down your SS, the temps will rise so fast you will have your unit restarting in less than a minute, and be sure your compressor can't start until pressures are equalized, and that takes at least 3 minutes, so your unit will not start at all, and if it happens to start, your computer will crash because of the core temp needed for stability in an overclocked system.

What about voltage throttling for the compressor? Would that work?

MeltedDuron
07-16-2006, 09:08 PM
you'd need one hell of a resistor, I wouldn't like to think about it. Compressors don't work that way though, they run at the speed of the AC frequency iirc

Well guys my spacer didnt work, i got the system to boot and load an OS. But if you quit working the cpu for more than a couple of mins the system locks. Looks like my jinuv2000 system will be put aside untill i can get a e6700and a conroe motherboard that supports sli. I hear from jinu that socket 775 mounting of the evap. is a real biach.. im not looking forward to that.
thanks for the help

Doh... 3/16 was what I planned to send out -_-;
I thought I kept the system bit overcharged but apparently not enough... bleh... -_-;
Sorry to hear that your cpu got major cold bug. Maybe Ron's 1/4" might do the trick for you?.... or we could look for something even thicker... (cringe at the idea).

Thanks jinu but i dont want to risk the phase system (all these power on/off's) Its perfect and it wont be a month (i hope) before i can get my hands on an e6700 and a sli conroe motherboard. once i have those this system will be perfect just the way it is. Am i going to have a hard time mounting the evap??? how would you know if the motherboard hasnt even been released yet :( Ill unload this board and processor for cheap and wait.. the phase system is working so well i just dont want to risk screwing it up.
Thanks for all your help jinu

If you can boot Windows and use the system as long as its loaded, you should be able to more or less cure your cold bug by switching over to the MPS Multiprocessor HAL. This keeps both cores nearly fully loaded at all times.

Raising your multiplier and reducing your HTT should also fight the bug effectively.

Of course there are several hardware solutions as the ones outlined in this thread which involve raising core temps through spacers, or even adding resistors to heat things up...in my most humble opinion these aren't the routes to take as its sort of a waste of the unit if you have to cripple it. In some cases its necessary but especially with your FX you can probably keep temps very close to a minimum and fight the bug through software tweaking. Less work if you look at it a certain way and also higher potential overclocks. :)

The idea of a spacer really doesnt sound bad... Maybe try brass, aluminum or steel....? (It don't have to be copper...)

I have a Gfroster in my unit and to prevent it from shutting down on restart (damn Asus board) i have it on a 2nd powersupply that has its pins jumped to run w/o a computer. it works perfect for testing for a overclock, then i hook it back up to the powersupply used for the computer

We already have that in our to do list for the next froster firm, so you don't have to use another psu.

when is this new firmware schedualed to be available? is it just going to be an option in the software to dissable the part that checks for psu power? that would be helpfull.

Not exactly, the idea is to give a little delay option, because that is what happend with the asus mobos.
Next month for sure, maybe sooner.

outcast623
07-18-2006, 09:28 PM
sorry i dont really understand, by delay option is it like, it sences the power switches off like on a asus reboot, normaly gfroster shuts off but with the delay it waits to see if the power comes back on in a certain amount of time? then if it sences the power comes back on the froster doesnt shut off?

bear with me! it sounds like a good idea because i have this problem with my froster and asus board.

Basically what I requested was the single stage not to register the computer is off till about 15-30 seconds after it shut off. Bit of delayed effect. I believe this is how new vapochill or mach firmware avoid the problem with LGA775 in general.

outcast623, there is a hardware way to produce the delay off, and avoid the controller shutting down on restart. No new firmware, needed.

Golden_Eagle
07-19-2006, 08:21 AM
Sure, there is a hardware way, add a capacitor and a diode in the circuit...
Point is... users dont need to do the job, cause they paid for it to be done. So firmware comming up soon.
Cheers.

outcast623
07-19-2006, 08:21 AM
you care to fill me in? instead of just saying there is a way? i prefer to just use a firmware update insted of doing something to mod the gfroster.

EDIT:AHH you beat me too it! Thanks i share the same feeling

gsmaster
07-19-2006, 02:29 PM
I just told that, in case you wanted a fast solution, with no need to wait for the firmware.
Surely a firmware update is the easier solution for the final user.
