How so? This card is so much better than the 4870x2. As for the waterblock problem. I'm starting to believe it has to do with the way people are mounting their EK block because if it was a real problem with the card it would not matter what waterblock was used and we would be gearing more about it.

^^
Don't get me wrong m8, 5970 would probably be my next card. I just read about ppl having quite a few probs with it and not all of them wc it with EK fc. In my country u already see ppl selling them and this isn't something that happens often.
I just stated that i'm glad i'm not an early adopter...
-
After disabling ULPS 4 days ago, my 5970 + EK waterblock system is now rock-stable in 2D and 3D. I'm gaming non stop almost 12 hours a day, and didn't got a single BSOD, freeze or any other issue in games (I'm playing Dragon Age, Resident Evil 5, Batman AA, Torchlight).
I also did a couple of hours of Phtoshop CS4 and AVC-HD video editing without a single problem.
So it must be the way people are mounting the EK waterblock. Or a really strange driver problem. I don't know.
I had some problems the first 2 days. But now everything is working fine for me. Disabling ULPS and letting my computer working 24/24 solved all my problems.

I guess u understand that this can't be called a solution nor "everything is working fine for me"... ;)

I know. But I have over 25 computers in my 2 business that are on 24/24, and even some pretty old ones that are 6-7 years old... working 24/24 since the first day. Not a solution for you maybe, but for me it's ''standard procedures''. :)
If I power off my computer, I only have 1 message ''Driver has successfully recovered''' blah blah blah, once, and only once, in the first minute at start-up. Then I'm good to go until the next reboot. Not a single problems if I don't close my computer, and a single message if I do.
So I don't call this ''major problem''. I can game for hours and do everything I want to do for hours.
I know that for some it me be ''major'', or ''fubar''... But for me, I can live with this. If I can game 12 hours in a row without a single hiccup. And then edit over 200 gigantic fullframes Holidays pictures, and then edit gigantic AVC-HD video files for hours without any problems... Why would I say I have ''major problems''? That ''solution'' is fine for ME. :)
Hope the next drivers will be better and solved that small annoyance.
-
Srsly I don't think that the EK is the problem. I use em too and not a single problem at all.
At the moment most of the problems are due to the drivers.
I had these 2d problems with the stock cooler too. Check this thread and try it: http://forums.amd.com/game/messagevi...hreadid=122942
Guess it's easier to blame somebody else instead of searching somewhere else...
-
Hey guys,
sorry I was on holiday for a few days. Just put the stock cooler back on my Diamond card, and used MX-3 for TIM on the GPUs.
Booted up, immediately started FUR - freeze :p:
Rebooted again, worked fine. If I had waited even 1-2 minutes before firing up FUR, it would have worked too. I guess it really is one of the cores being temperature sensitive, since with the stock TIM I couldn't reproduce the issue. ATI really needs to revise these cards...
-
Since last sunday morning, I didn't had a single look-up, error message, BSOD or freezing. Heavy gaming sessions, Photoshop CS4, HD video editing all day long. 6 days without a single problem. Boot, re-boot all I want. I even re-enabled ULPS in the registry. :) The only ''tweak'' I did was raising 2d clock settings from 157/300 to 400/900 (thank you Sargatanas). :)
EK waterblock + 5970 is rock solid for me. :) My temps are really low, idle and load, so I don't think there is any ''cold bug''. OC or not.
I think it's more related to the way people are mounting those waterblocks... Or drivers related... Hardware is fine IMHO.
-
OK can you give us some guidance then about how you think the mounting is causing this? What did you think you did differently?

Yeah I'd like to know as well because I personally feel the mounting has nothing to do with the issue but please prove me wrong.

Yeah right.... cause I'm a real noob, and it's not like I have proven that MY card does indeed suffer from a "warm-bug" - the hardware is fine :rolleyes:
YOUR hardware might be fine, mine certainly isn't. Like I said, I have mounted the same block on a new Sapphire card and everything went perfectly well. It seems to me that ATI has some severe QA issues with the 5970 series.
As for the EK block, it is fine, probably with or without the "double pad mod" - still can't hurt to do it if you got a level card, so all your chips will make good contact.
-
I'm sorry. I'm really ''the noob'' about all this. I'm a pharmacist/biochimist/chemist, with over 60 employes working for me, and all woman!!!!! so I REALLY need to relax at the end of the day... so I'm playing with computers to relax and have fun. It's a hobby. Didn't want to imply that people in here are noobs. Far from it! I learn SO MUCH reading those forums! I'm french, so sometimes I'm having problem explaining myself in english. English is my third language. I'm sorry for the misunderstanding. :(
I just want to help, that's all. I just want people to have fun with their 5970 like I'm am. I only wanted people to know that there is some "hope", that there is really some 5970 out there working fine with the Ek block. That's want I wanted to say. Not to imply that people in here are noobs! Not at all! Sargatanas is also rock-stable with a 5970 and Ek waterblock. So there is some 5970 working fine on water. :)
I just hope people in here will solve their problems. Really. Even if I'm ''the noob'', I have the feeling that all those problems are drivers related. Or at least a major part of it is because of non-optimized drivers. Changing my 2d idle clocks solved all my problems.
So if there really is a harware problem with the 5970, I hope we will find a solution together to solve it. That's what I wanted to say. :)

Hey. That's a change! Usually I receive e-mails from people to get them some Viagra or Cialis without prescription. And I receive ALOT of them... :)
And I'm not joking. ;) Particularly on french forums where I go regularly, you would'nt believe the number of e-mails I get about the ''blue'' pill. :)
-
Well it's quite difficult to say what causes the problem.
So far, I used the EK block on 4 Powercolor 5970s. For me, it made no difference with one or two pads because I mounted the first 2 EK with just 1 pad (and it was rock-stable too). Seen that later in this thread and changed it too just to be sure.
I had problems with the 2d clocks, even with the stock cooler but I was able to fix it with a new 2d profile.
Haven't seen any "warm-bug" so far too since my cores run at about 20°c without any problems.
I don't think that Levesque wanted to call anybody a noob at all but I got what he meant: I've seen enough ppl who did a lil mistake and were blaiming the fabricator of the product.
It's like using the swiftech xt with bitspower comp fittings and complaining bout leaks cause you didn't used the right o-rings.
AMD has alot to fix cause most of the problems are driver related....I talked with some of em earlier, they know some of the bugs but not all of em like the 2d/powerplay issue with Win7 64.
I think we must be patient and see what they will change with the next catalyst release.

well I just got mine today ,that thing is gorgeous ,the nickel acrylic
I install it with a problem ,the temp drop in big from 60ide to 28c
now I oc to the max 999mhz and no problem so far
except for fact that my scores drop even a the old clocks
so right now I installing vista 64 in another part. to test againg
that way I will know for shure that is not software or drivers problem
I post later the results ,if it drop my scores again ,stock cooler is back
to stay, burn in hell 5970 it like hot:shrug::D

So you have a Sapphire card working fine with the EK block....then what is the issue with my Sapphire then?
Could you please let me know the bios build number and date of your card and if it's possible to upload/email it to me, thanks.

Lowdog please explain what you mean by throtteling back
the water block didn't give me any lockups ,I can't get the darn thing to crash no more even at max oc
the crisis benchmarks are solid , but for some reason my vantage scores when back to like 25,000
is not a big deal cuz runing good now
but I would like to go back to 27,000+
it hard to believe that lower temps give less points
it make no sense
however your issues ,mine and everybody else, might get fix with new drivers;)

if the core, or the VRM's get too hot, it with throttle down (reduce the speed of your clocks). I guess the best way to see if that is happening, is to use GPU-Z to check max VRM temps, or use afterburner/rivatuner and have it overlay the clocks so you can see them when stressing the card (if you don't have a G15 keyboard).

Hey Mr Farken, can you do us a favor, take a screen shot of CCC Overdrive showing core 2 please, just want to see if it's showing 000 for GPU and MEM clocks or if it's showing 157/300 at idle.
My card is cold buged at temps below 30C it appears, or else it's not cold buged and I just have to run furmark upon first cold boot up to just kick it into gear...after that everything is fine........perhaps it's just because the second core needs to be woken up because with the block on it it runs so cool at bootup that it doesn't know it's alive and needs a kick to wake up :ROTF:

Yeah, you aren't taking screen captures at the right time... well after cards cooled.
1. set up any and all programs you want to display in your screen shot (CPU-Z, GPU-Z, ect.)
2. toggle every item in GPU-Z to show MAX
3. run benchmark
4. immediately hit screen capture key upon benchmark finishing.
5. save image.
The image should show your card at high temps, and to the right you should see the graphs going down as the load temps start to decrease very fast, soon as the load is off them (benchmark exits). The #'s will show the MAX data, since you should have toggled them in step 2 above ;)

alright I run furmark xtreme burning test for 10min set gpu-z to high reading
here the pic,the vddc are to hot I guess they are not making good contact with cooler ,which one in the pbc are dose ?
the gpu's temp drop 10c with the new cooling ,how they can be such a huge temp differences ,40c gpu vddc 126c damn:shrug:

Those are the VRM temps. You don't want your VRMs at those temps under normal gaming. So I'd run your most stressful game with GPU-Z in the background and see what temps you get. If they are still in the 100-120's, dial back your overclock and/or voltage, cause it will just lead to the card throttling (reducing clocks), or possible damage (parts are probably rated for 125C, but i don't think you really want them constantly at those temps).

yes I understand that at those temps is going to fry my card
so i need help to cool down the vrm's
were in the pcb are these ? mark then in a pic please ,if you didn't askfor this temp check ,I would continue to run oc and probably burn the vrm's thanks for the help :up:

Just finished assembling my EK waterblock on a XFX 5970 and i can confirm its got the cold bug. It will freeze in about 1-2 mins while in 3D if under 28 celsius. Once the card is at 29 or more, no more freezing. I already set the fan to 25% (least i can) and will test again once the card cools down enough. If it doesn't work, i'll try a bit more voltage, see if that fixes it.
Anyone found a fix for this already?
-
More voltage might get you to above the magic number since yours is a few degrees lower, my magic number is like 32-33, more voltage still doesn't get me that high so my only option for now is pump off. New 5970 coming on thursday crossing my fingers for no cold bug. I've checked a million threads it seems like nobody has anything close to a fix. Good luck.

I can confirm the same issue here. I run my rad with one fan running and use furmark to get it warmed up. I have tried a multitude of bios' with no luck. This is with an ek fc block on my sapphire OC 5970. The card simply needs to be warmer than 30c in order to run stable.
-
Well, sorry to hear that :(
Trying to put the fan at a fixed value did nothing for it. Fortunately i don't start gaming right after i turn on the PC and it usually goes to 30º (idle temps) in 25-30 mins. Might even forget it's there in the summer, but it's still very annoying. I am going to try a different approach now, overclock it some more and pump a bit more of voltage as it's running @ 850MHz and 1.150v for now. Will try 900MHz and 1.250v :shrug:
I'll post my results but have no faith this will solve the issue either. I even twitted CatalystMaker about this (Terry does answer sometimes) but no luck with this subject.
-
Sorry for double post but...
I checked and re-checked and checked once again, the symptoms are: If i turn on the PC and go game instantly, the video card is at around 20-22ºC and all i get is a video crash. Sometimes it takes 1 minute, sometimes only 10 seconds but it DOES crash always.
If i let the PC on for a few minutes, do my stuff, browse a bit and THEN go play some game (only tested 10+ minutes after PC is on) EVEN if the video card is still at 23-24º, i get no freezes at all.
Bottom line: If i run a game 10+ minutes after the PC is on, everything works perfectly. Talk about odd. Need to test with less time after PC is turned on, but it's fine by me already :up:
Just thought i'd let you know.
-
That's excellent news I don't think it will help my case (think I've tried it already can't remember) my pc has been on for 24 hours I'll turn my pump on and let the card cool down and see what happens. Report back soon..
Edit: ok cooled down, starting from this state:
http://i787.photobucket.com/albums/y...E/hardlock.png
Edit 2: bfbc2 which runs flawlessly with the pump off hardlocked system after like 45 seconds, oh well new card coming tomorrow, if that card has cold bug I'm going to either 2x5870's (I already have one) or 2 fermi 480's
-
This cold bug is about the ONLY time I'm actually glad I live in a tropical country.
Don't think I'll ever get it anywhere near 31-32 with a single 240 rad.
Anyone here got preference on which waterblock would be best for the Sapphire 5970 OC?
I don't see anyone using other brand than Ek here, but I thought I'd just check up with you guys.
-
Hmm, anyone dare to try their card without a pad on the PLX chip? Well, perhaps not without anything at all, but at least something less effective than a thermal pad? Just struck me that those chips had some issues with cold on older cards, not @ 30C, but they use a new rev on the 5970, so might be worth a try if anyone feels brave enough..
-
So if my Tri-Crossfire set-up 5970 + 5870 with EK waterblocks on both are idling at 23-24 celsius and never going over 28 celsius when gaming, can I also "confirm" there is no cold-bug? :)
Asus 5970 + XFX 5870. I just played Batman AA for 1 hour, and the 5970 cores were at 28 celsius, and the 5870 core was at 27 celsius.
-
@levesque: clearly you have no coldbug
anyway, just dropped in for a quick update, got new card today and under water:
http://i787.photobucket.com/albums/y...E/new_card.png
About to try some bfbc2, usually hard locks my whole system in ~2 minutes, *crosses fingers*
Also quick note: not doing the profile to bring up 2d clocks and not getting any weirdness in windows so maybe this card doesn't freak out 2d wise. Here goes..
Edit: thank goodness, should put to rest most 3d/coldbug related issues, it's the card, try and trick your vendor into an rma (sapphire wouldn't claiming card is fine on air, so think of something more clever than I did :)
played bc2 for awhile and ran furmark for 5 minutes, both of those wouldn't last 30 seconds before, this is new card same vendor same block same drivers didn't change 1 thing, put on the ek block exactly the same as first card:
http://i787.photobucket.com/albums/y...no_coldbug.png
-
Am I correct in assuming this is a hardware bug, and not something they could write a driver for to fix?.. like one that simply ignores temperatures?
Or is it some hardware glitch that no amount of driver revisions is going to fix?
-
I am guesstimating from fact that people reported bugs for same cards having it or not and fact that after all this time since 5970 was introduced in market no software/bios fix exists (apart from hack of overclocking @2D to artificially rise temps), that it's no driver or software bug, but rather hardware one. It's wild guess of course.
-
Someone on amd forums said switching to asus bios completely fixed his cb problem. That's only 1 person but it is sort of good news and makes me think possibly bios update can fix it. I would have tried this had I not already ordered/recieved/installed a replacement.
Honestly though, who knows. I wish good luck to all those with the problem, my suggestion is to try and rma.
-
Anyone got any idea how to detect these problems while the 5970 original heatsink is still on?
Seems to me that most people having problems only after they changed to water cooling.
With my own EK waterblock coming in another 2-3 weeks, just thought I should test my GFX board first so I can RMA right away should there be problems.
I already got 1 295 gfx card that doesn't seem to want to do any 3d apps.
And since I had bought it overseas... there's no easy way to get warranty claim.
Having another defect gfx card would be a nightmare.

It's simply because with original heatsink on air cooling card never has that low temps to trigger bug, only on water :)
- If you lived in some country with cold winters, i'd put case outside apartments, i beleave you might trigger it that way too :)
Who knows, maybe something can be made by some air conditioner aswell.

Well, i just tried this. I can't give you any results now as it's kinda warm here now and i can't get the card to cool down to the usual 18º boot temperatures. Tomorrow morning i will test this as soon as the computer boots but i don't have that much faith it'll get fixed :shakes:
Like i said, not a reason for me to RMA it, but knowing that it's there is annoying enough :rolleyes:
EDIT: UPDATE:
I let the PC shut for 3h a while back as it's night already and temperature dropped considerably, PC booted with the card at 22º on each core, ran Crysis benchmark immediately after i got to the desktop and it went through just fine. If i did this yesterday, i would be greeted with an instant crash. This is a good sign, but i'll confirm tomorrow after the PC has been off for over 8 hours.
-
hmmm, well see if this works then. :shrug:
-
Unfortunately it doesn't. I'm keeping it as it is but it's still a shame.
Turned on the PC this morning, ran Crysis benchmark just for a test and it hung after 20-30 seconds. I shut it down, restarted and used the PC again for ~15 mins and tested again, no issues whatsoever.
-
Imho ati/amd can easily implement fix in drivers for it. On 3d app launch check if it's one of problematic coldbugged gpu ID and if temps are too low, if it is, automatically momentarily rise clocks to "preheat" gpu, and only after few secs allow resources for launched 3d app. I'm shure that they'll never do it this way though :/
-
I doubt they know which GPUs are troublesome. I am not considering about buying a new card and selling this one with the original cooler because, just imagine if the new card still has the same problem... All the hassle for nothing and wasted money on top :(
If only i knew that the new cards being produced don't have this problem anymore...
Wonder what is happening exactly, if it's the MOSFETs too cold, the PLX chip, the GPUs... Maybe some chip that doesn't like going from "too cold" to "too hot" that fast :shrug:
Raising the idle clocks is not a solution for me either because i like my PC to use the less amount of power possible when idling.
-
Well, been thinking what can be done here.
There's a few options, and depending on your loop configuration, may/maynot be applicable for your system.
1. Use something like bigNG, Alphacool, etc to control your fan/pump so the temp doesn't get too cold/hot. (best way I could think of at the moment)
2. If you happen to only have the problem during startup, you can use a relay + timer to set an automatic delay for the pump/fan to turn on. Recommend turning off fan instead of pump, cause the temp would drop like a stone the second it's turned on. You may also vary the speed of the fan to ramp up slowly.
3. If you overclock your CPU, may consider putting all the loop you got into 1. You may have to reduce the overclock this way, but the water would be warm in no time. Unless of course you got huge radiator(s).

I really doubt its the actual GPU's, as 5870's seem to handle the cold very well. My bet is on the PLX atm, but seems weird nonetheless

I got a dedicated loop for the 5970 with a FESER 240 radiator. Keeps the card under 28º idle (and it's not really cold here now, about 20º) and reaches high 40ºs when stressed. This loop is already controlled by the aquaero - the fans idle until the water rises above 25º but the card will already be under "operating" temperature by then, that wouldn't solve it.
Anyway, i lost the love for €150,00 of mine and sold the XFX 5970 BE to a friend who doesn't watercool ever and gonna try my luck on either ANOTHER XFX 5970BE or a PowerColor... Still have to decide which.
-
Wow, I figured I was pretty much alone with this issue. Guess not..
As much as I love my HD5870 (that card LOVES cold), I have to say I am pretty disappointed in ATI. WTF were they thinking sending out cards that coldbug at ~30C positive.
Epic QA fail...

So Far I see:
Warm Bug problems:
- Diamond
- XFX and BE
- Powercooler
- Sapphire
No Problems:
- Diamond
- Asus
- XFX BE
- Powercooler
- Gigabyte
What a mess.... Looks like a total coin toss, no clear trends.
-
Mine's a XFX BE and its got the ColdBug. I found an ASUS dealer, gonna try ASUS instead of PowerColor.
Definitely looks like a coin toss... can just hope i hit the spot now on a 50/50 chance :shrug:
-
hmm got a xfx 5970 be coming tomorow
so no way to tell witch ones do it or a fix :eek:
what about the powercolor 5970 lcs any of these pop up with it, if not what did they do nothing in the one review on it

I could be completely wrong though...

i would think anyone that payed 800 for a 5970 lcs card with a cold bug would post something somewhere and i can't find nada
how hot does the PCIe bridge chip get
and has anyone tried to add maybe tin foil or thin paper on top,between heat pad and block to add just a little insulation to it :shrug:
what else does a 5970 have different to 5870

Mine with the bug was sapphire, didn't want them left off the bugged list, they all just slap stickers on reference ati boards anyway clearly it's an ati problem. I see it popping up with more and more watercoolers they will have to take notice eventually.
Replaced my bugged sapphire for a new sapphire, new card works perfectly no bug, I can see not wanting to go through the hassle but I took a chance and it paid off, if I had got another bugged card I would have sold both and went dual 5870's or 480's. Glad this issue is over for me.
-
So summing it all up most sell rebadged reference (and one needs reference for full cover for reference PCB to fit), and after that it's game of luck no matter what the vendor? (i'm guessing that few vendors that hadn't yet reported coldbugged cards simply might have a bit more extensive QA tests or by same game of luck such as particular vendor not as often used for LC :) or LC-ers got more lucky with particular cards. Afterall, noone has extensive statistics of behaviour of at least 100 gpus of each vendor/each revision/each stepping under liquid cooling :/ ).
-
Is it possible that the ones that have the cold bug here are the ones who burn test their card before fitting the water cooling?
Did anyone who bought their second card because of the cold bug, burn test their card before fitting the waterblock? I'm suspecting that the 2nd one worked fine simply because you went water immediately, without burn testing it.
My theory is that the burn test heated the chips too fast, too hot, that it would simply break the internal connections when it does cool down. When it heats up again, it'd expand and reconnect. Thus you got connections that'd only connect on high temp.
Is this too far fetched?
-
Imho yes, too far fetched. With all that megacomplex circuitry i'm guessing it would result rather in on/off working or not, with some basic inner hw or bios tests. I'm rather thinking that most probable is badly designed thermal monitoring (or power circuitry that might change depending on thermal readouts or something else depending on them like dynamic clocking/voltage) without taking into account possible lower temps with liquid cooling. And seeing it not fixed yet with bioses/drivers, probably it's hardware part, not software one. Maybe some new pcb revision might fix it?
-
In my case, got home today with a GIGABYTE version of the 5970 (ASUS was way more expensive - wonder why?), assembled the waterblock, booted the PC and instantly went into Crysis benchmark like i used to do with the XFX and by some miracle the bug is a goner. It went into the benchmark at 20º celsius, came out of it at 28º as it didn't even have time to heat up much and never crashed.
So long coldbug, but this is hardly the way to solve things as i "lost" 125 eur to "fix it". Nice going ATI... real nice going. Bah.

I've just mounted a Danger Den DD-5970 on my XFX 5970 Black Edition and the smaller CPL-2-50 chip didn't had any contact at all with waterblock:
http://i43.tinypic.com/qsjrdc.jpg
I've applied THREE extra layers of thermal pad to make them have contact
http://i41.tinypic.com/znass1.jpg
The chips are at same level...

Just ordered xfx black edition yesterday and now I'm hoping I won't be sorry. Is this happening on all the cards?
-
Nope, just a few it seems. Still, way too many to call this an "isolated issue" :shakes:

I was so looking forward to this build now with this info I'm really confused with what to do. I would hate to buy a water block to use as a paperweight. :shrug: Has any one tried this with any success?

Sapphire 5970 purchased in November 09 and XFX 5970 BE purchased in March 10 both have the problem with an EK block on them but are fine with the stock cooler.
Sapphire overclocks like a wild thing with 1.15v volts and the XFX is a dud clocker requiring 1.2v just for 850 core....pos.

hi
i hive SAPPHIRE 100280SR Radeon HD 5970 (Hemlock) 2GB 512 (256 x 2)-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card.
i install the EK-FC5970 - waterblock , NO problem with the temp...http://www.performance-pcs.com/catal...db03201403e3f1
but my problem with card is that sometimes when playing BFC2 online after a good 1-1/2 hours my system just reboot. i ever had this problem before with GTX-285,
my PSU is ABS 1100W. I'm confused why this happen. other times i can play for 5 hours with problem at all and temp TOPs of 43c holding at fullload...
with AMD driver 10.4.
confused help.
thanks
