X1950XTX coldbug !

[blind_ripper]

got mine this week tested on modded mach2 .
it coldbugs hard :s 0°C = blackscreen , any idears ?
vgpu in ati tool @ 1.575vgpu and core 780core al good 0°C blackscreen :( .
hope hipro and the gang get this :D

[TaPaKaH]

looks like another great videocard is ruined with the coldbug :dammit:

[Gautam]

Did you disable ATi Hotkey Poller?

[blind_ripper]

Did you disable ATi Hotkey Poller?
yes i did , no ccc installed .
its a retail card from sapphire

[Gautam]

Hmm...what happens if you try booting into VGA mode with the card subzero?

[blind_ripper]

i boot @ evap under 11°C no boot so card wont boot under 20°C core :s this is not good :(

[Gautam]

:brick: This sounds like a hardware cold bug. :mad:

Maybe there's a chance its just coded into the BIOS, and a different BIOS could fix it...?

gone test it , if some off the pps with the non coldbugged X1950XTX post there bios :D .
i have done soem coppare runs with X1900XTX VS X1950XTX . the GDDR4 makes is like i gift from heaven .
my X1900XTX with 1.2ns GDDR3 no coldbug on core tested up to -33°C on a modded mach2 :) .
but this is no fun 0°C bang blackscreen , maybe its the new drivers running 6.9cats

[Dynasty]

My ati 1950 boots into XP pro @ -48 C no problems with single stage...:)
Could be driver related...use 6.8 betas

[IvanAndreevich]

I thought there was another post that said X1950 doesn't have coldbug even with cascade?

[blind_ripper]

My ati 1950 boots into XP pro @ -40 C no problems with single stage...:)
pm me ure bios , dynasty wht drivers and brnad of card ?

BBATI,
im using 6.8 beta the ones that came with card..
Card is not retail though :D

edit.

thx for the bios , gone test tomorow . is it a XTX bios ?

[Dynasty]

yep, tested fine @ -48 C's with ATI X1950XTX...;)

[G H Z]

Wonder how kinc's doing with the mousepots ;)

[Dynasty]

I think managed to come across an
solution to any X1900/1950 cold bug card...:D
If this works these cards can be work down to -98 C's...
talk about some real cold with absolutely no cold bug effecting boot up..:)

No post or black screen in windows?

Wonder how kinc's doing with the mousepots ;)

The first X1950XTX I got coldbugged at +5C (!!), got a new one to test the coming week. The mousepots are wunderfull, just amazing. Another problem with the new catalysts is that they have a failsafe that shuts down windows at boot if the temp is below 0C. You can activate the driver manually after boot but the performence will take a hit. Anyone tested 6.9 subzero?

yeah me 0°c = black screen :s with 6.9 cats.
any one can explain me how ati tool works , it wont go to oc'd clocks :( .
killed ATI SMART service , hotkey is still running , no ccc installed .

More info on this plz :fact: :eek:

[G H Z]

ripper,

Kill both ATI Services with Windows Services console - type services.msc in run box. Do not use msconfig, the ATI Services are auto starting and msconfig only controls the startup condition, they may start again in the same session unless they are disabled.

[G H Z]

Jesus thats bad!! The shutdown @ 0° is ATI Services, if you disable them that doesn't happen on X1900 but of course you know that right ;) Is macci still with ATI, maybe he can help on this somehow? I'm also wondering where Sampsa is, anyone hear from him?

[blind_ripper]

got winclk working :D
http://i3.photobucket.com/albums/y90/blind_ripper/X1950XTX15k05.jpg
gone do some more testing this afternoon :D

[Joe Camel]

GOOD LUCK!!!

i think there are A LOT of us watching these threads to see how the x1950's take to the cold!

:toast: to you for being our Guinea-pig :D



EDIT: does WinClk allow for higher clocks than OverDrive?

[blind_ripper]

changed drivers to 6.8 beta that come with the card , still coldbug .
http://i3.photobucket.com/albums/y90/blind_ripper/X1950XTX15338a05.jpg
with WC , max vgpu but any higher and lockup .
any one has a good tool for flashing bios ? gone try that .

[Revv23]

if i remember the press sample x1900xtx's didnt have the coldbug either, looks like ati pulled the same crap this time around.

[WiCKeD]

You really think they tested it on sub-zero temps just to disable overclocking for the handful of people who run cascades? They hired macci, so they have to know it helps them with publicity.

May be a retail only bug, but I can't believe it would be intentional.

Use ati win flash for flashing bios works like an charm...:)

I can't upload it as I get the max. of 5 uploads message...:(

I dont know what they did, but there is a difference between reference cards that dont have coldbugs and retail cards that do, is there not?

Just as steve got ahold of some AMD64's without cold bug from his AMD source/

[blind_ripper]

flashed gone put prom on it this weekend , bios seems to be the same winflash showed serie number of bios , perfect the same ;)

[blind_ripper]

just mesured card vddci in real . atitool set to 1.58= 1.85vddci in real :s watch out .
any one got vgpu mod ???
vgpu is normal , 1.575vgpu = 1.571vgpu real :)
Edit: 2.18vmem atitool = 2.07real :)

I run my sapphire X1950XTX with DI this monday, drop som DI without aceton and boot up in bios works great, but when i should boot in to win i came in but get that warning flag the CLI.DLL could not load i think thats an driver issue, and i think so that i will try again and boot with an empty gfx container and when im in to win i will add DI and test if it works that way or what do you guys think of that or is it the driver or harware related coldbug..
BTW i cant change driver at all try from cat 6.5 to 6.9 nothing works it says that i should install a proper vga driver first what's that means i have'nt a clue ,heres pic of what i've done on DI cpu on Di and shifted över to air on gfx again..

The official catalyst drivers dont work with x1950 yet Chef. Use the 6.8 or 6.9 beta´s....they work :)

nice but card have hard cold bug !
btw fix ure time on super pi :) got 10.90x sec @ 4.68ghz , had to boot into windows :p
32m @ 4.59ghz easy

ok will ty 6,8 beta and se hows that work....

blind_ripper: yea will do that must tweak my mem then i will go under 11 sec ;)

[chefnr1]

my friend runs with DI now on X6800 and x1950xtx he boots upp with no di in gfx container after that he add it and run great with it at about -50c

[chefnr1]

talking about the coldbug on X1950XTX! can it be a hardware issue or a driver issue, because when i test my with DI i i filled my gpu DI container about half full with only DI pellets an when i boot up it came up a banner that said that CLI.dll could not load an the system shut down so i change over to aircooling on the card and then it worked just fine had DI on cpu aswell , or could it be a bios issue? if theres someone who have a X1950XTX that can handle subzero i would like to test that bios if theres someone who can give it to me for that i'll be very glad...

[symphy]

Fellows, come on... Whats up now?! No new results? Same mess like with X1900?

I just ordered LN2 and have my dualhead waiting for the ATis which should arrive tomorrow... Dont tell me this will not work, i saw this thread not early enough.

What about Vmods - same points like X1900 series?

no mods , vgpu is changed .
time that or mod master hipro and the rest of team hellas get to the point !
i dont have my X1950XTX any more changed it for a golden 7900Gt :p

[symphy]

other ICs? Damn. Can someone post pics of the ICs at the location where the previous one have been located? I can figure out the mods, no problem i think...

[ewitte]

I wouldn't even bother with low temps on these cards unless your in the negative temps. With a 40-50C drop in temperature I did not see an improvement at all with my X1800XT and it was a pain to insulate (didn't do it correctly anyway which caused a dead board). I could set about 40Mhz higher without the instant lockup before but it would lock in benchmarks halfway through. I was lucky to get 800Mhz on a few tests but I had achieved 790Mhz before without it and on more tests.

People with vapo and liquid nitrogen will probably see a difference :)

[symphy]

My unit will ran the cards under -40°C - loaded.

So Vmods needed... And mods against coldbug :X

not yet , u have to be lucky ! my last X1900XTX did like -33°C idle core and no mods needed , the first one did -10°C without mods and -30°C with mods ;) .
pm hipro :D , maybe we can start the hunt for the coldbug again like with the X1900 how to part solve it

[symphy]

I wrote to hipro5 and other ppl, but no replies yet. Seems like something we are not supposed to knew right now... No problem; I'll try to figure them out as soon as my cards arrive...

[symphy]

Back again...

I mounted the cooling today; -46 idle on both evaps. Crossfire enabled with the 6.10 Catalyst results in 6700 Marks on 3D06 (with X6800 ES at default); Catalyst 6.8 will boot into windows but shuts the system down (like shuting windows down with alt + f4... "windows is shutting down")

When i switch the compressor on when the cards are running in windows, it shuts down at approx. 0 °C.

DNA Driver reads -40,67 correctly at the core but doesn't allow crossfire.

I need to try a modded BIOS with other shutdown temps or killing the services like mentioned earlier.

I'll report in soon.

Try this, on air install drivers, enable CF and re-boot. Next disable the two ATI Services but first CCC has to detect something before you can disable them so give it a minute or two. Ensure CF is working then open services.msc from the run line. Disable ATI HotkeyPoller & ATI Smart (don't just stop them) and re-boot again. Now the shutdown at 0 is gone, at least thats what did it for me on 6.8 and prior driver versions. This also works for single card.

[symphy]

Also worke fine for me. But i can't overclock even 1 MHz :X. If i do nothing, my card run at 2D Mode.

Using AtiTool or winclk will result in a freeze; rivatuner works very well - but only for one card; i can't change the clocks of the slaved XTX.

Any ideas? What programs are you guys using? Driver is 6.8 beta.

[Revv23]

does ati tool freeze right away or when OC?

Maybe you have to adjust the voltage....

[G H Z]

You can select each card (Settings | Use Device) in ATI Tool from the drop list. Set voltages (& fan speeds if your on air) before you increase clocks ;)

[symphy]

Already tried that.

ATi Overclocker allowed me to increase the clocks again to 3D stock level and higher (testet up to 700 MHz with 1,6 Vcore). Unimpressed -30 °C loaded at the cores. (3D 06).

But: Bad Results. Aquamark 119k Points, 3D06 7200 Points.

Don't know what to do anymore. I'll try the latest ATiTool now again and look what will happen.

[loc.o]

Sounds like 1 card scores to me are you sure CF is working?

[symphy]

Enabled at the CCC for sure.

Tested again (the unit is running while im typing this) - voltage increasement via ATiTool and Default clocks are at normal speed during Return to Proxycon (i expect about 30 fps), but not stable. Little errors (looks like RAM, black things flying through the screen) and freeze after 20 seconds.

I will try 6.10 beta now as 6.10 final didn't worked for me.

So you mean that it can boot subzero when you do that???
