If you are only getting this freeze with battlefield 2. Are you running a gigabyte motherboard. If so uninstall easy tune(comes with the gigabyte software cd) because that is a very big reason for crashes and bf2(punkbuster has config issues with any system easytune installed.)

No, I don't have anything like that installed, the only software from gigabyte that I've installed has been the absolute basics needed to run the hardware like the USB3 driver. The pc does not freeze at all with my spare 6770 card, no matter how many hours I spend playing a single game continuously. Bad company 2 is not the only game it freezes with, it will eventually freeze with every game on my steam list with decent graphics, its just that BC2 seems to make it freeze within half an hour and some of the other games take hours. So whenever I get the faulty cards back from PCCG, I test with BC2.

You don't have GPU-z running while playing bc2? It makes my bc2 crash 25mins or so from launching. Although I doubt this would be the case since you say it happens in every game.

This is certainly an airflow and case issue. The 6970 are hot cards, so when your running a crossfire setup you need to have a good cooling solution in place be it DIY or bought. As for fans try to grab some coolermaster 120mm rifle bearing 90cfm fans they are quiet and pack a lot of punch but are EOL. But don't use these fans too close to graphics cards (i.e. side window or in the case of HAF X that duct) as they will actually create a semi vacuum over the reference blower and increase temps from my experience.

So I'll look into adding a fan to my side panel. I've currently got... 1x120mm fan on the back (out) 1x140mm fan on the top (out) 1x120mm fan on the front (in) 1x140mm fan on the front (in) 2x120mm noctua fans on the cpu directing air out the top. What size fan do you recommend to put on the side panel, 140mm, 180mm? And should I have it as an intake or out?

intake if the gpu exhausts the heat out the rear or out if they just dump it in the case seems to work best but it can depend on the case bigger is better :) silverstone has some nice 180mm fans but that said although it may improve your temps the cards shouldnt crash even if reaching 98c and if they are reference cards they should work ok in a case with stuff all airflow as long as they can suck in some air that is under 50c sounds like you are having a shit time with rma hopefully you get a replacement this time if the screws have been tightened they may have replaced the paste to but that dosent mean damage wasnt already done when it first got hot what happens if you run occt stress test on the card

yea try an actual stress test to see if the results are able to be replicated outside of BC2, that call of pripyat benchmark is good for finding memory errors that would otherwise go undetected

I've finally received the second card (HIS 6970) back from the PCCG - RA team. Two months later. I've swapped out the Asus 6970 and I'm going to test this one for a few days on its own. So far it seems to be maxing out at 85C. The other card was maxing out at 94C. Both tested for half an hour. Both within an hour of each other. 18 degrees outside, 22 degrees inside.

I've tested each card individually and they seem fine. Only time will tell though. In crossfire the temperatures are much better than before I sent them to PCCG for repairs. Keep in mind that it was a pretty cold day today because it was raining. I'll post more on a stinking hot day when I can. 30min of BF3 GPU1: 89c 40% fan speed GPU2: 85c 36% fan speed 40min of BF3 GPU1: 86c 37% fan speed GPU2: 81c 35% fan speed 50min of BF3 GPU1: 88c 45% fan speed GPU2: 88c 45% fan speed 1hour of BF3 GPU1: 91c 50% fan speed GPU2: 84c 37% fan speed Apparently the cards just had the stock cooler re-seated and/or the screws tightened. That's what I was told by the RA guy over the phone. I'll keep you posted if anything happens when I test them on a hot day.

temps\fan speed looks good and should be fine assuming no damage was done while they were hot unfortunately bad mounts sometimes happen

I just sent my XFX 5970 back to pccg, they tested and also found it fault so they sent it back to XFX. XFX tested it and say nothing is wrong and sent it back... so now it at pccg. So two separate parties say its faulty yet xfx say no its fine, wtf do I do now?

Been playing with MSI Afterburner's custom fan control settings.
These where over about 2 hours and I wasn't taking times so they're few and far between.

The temperature in my room is 25c

GPU1: 84c 42%
GPU2: 79c 37%

GPU1: 83c 42%
GPU2: 78c 37%

GPU1: 83c 42%
GPU2: 79c 39%

GPU1: 88c 54%
GPU2: 81c 40%

GPU1: 86c 48%
GPU2: 80c 39%

I've just put an order in at PCCG for a Silverstone Fortress FT02B. So hopefully that should help the card temps a fair bit. I'll also be able to crank the fans a bit more because of the sound deadening in that case. If all goes well and I can get the cards to float around 79-81c under load then I might consider buying a 3rd 6970 for tri-crossfire.

Which also means that I have a 6 month old Lian Li PC-7FNWX with USB3.0 case up for sale. It cost me $239 + $57 delivery. It also has this added to it... 3x aftermarket Enermax fans, 2x140mm ($60) red and 1x120mm ($30) clear and a 2 bay intake grill ($30).
If you'd like to buy it off me then PM me. I'd be looking for about $200 + delivery (whatever you choose).

If PCCG have admitted that it is faulty then it is up to them to either repair, replace or refund it if it is still under warranty.

Well the thing is pccg haven't told me they found a fault. I sent it to them, they tested it then sent it on. So for them to test it and then sent it to XFX they would of had to find the fault first?

At the moment its "undergoing further testing" at pccg. Their RA dept have been keeping good email contact so that's good but if nothing happens by this week I'm going to call them.

Anyways I don't want to hog up your thread with my problems so I'll leave it there until i get some good news.

That's ok. Get PCCG to test the card in furmark before they send it back to you otherwise they will have to pay for postage again. I had the same thing happen, but I convinced the guy to test it properly otherwise I would just send it straight back with an invoice for the postage cost. Technically I would be able to enforce that invoice because if the card is faulty then it is the shops responsibility to repair, replace or refund it.

They can send you a postage paid bag from Australian air express.

I'm SoaS's mate and he told me PCCG did test it in furmark, but the screen resolution they operate at isn't high enough to show the problem. Also, we believe the problem lies in the memory, not cores, so it's hard to find a benchmarking program which will show it...

yer fur seems fairly useless for testing memory glitches
farcry 2 benchmark turned up glitches quickest on my gtx480 but testing memory isnt as easy as that some tests will show a weakness in a different part of the memory so depending on the card farcry 2 may show no problem when another test will

This is exactly the same problem I had with one of my 6970's. PCCG swore black and blue that it was fine and passed furmark so there was nothing wrong with it, yet it was crashing within 1 hour in almost every hi-res game. I also insisted that my problem couldn't be reproduced with just one card because I rum them as a pair in crossfire. They get allot hotter as a pair. I was a bit lucky in a way. For the HIS card, they sent me a replacement that did not have a back-plate and the PCB was slightly warped because they'd over tightened the screws. So I was able to send it back because it was a later model. The card they wound up sending my in the end has a few large scratches on the back plate but it works so I guess I'll have to live with it. The back of the card (where the exhaust is) gets extremely hot (touch test on the top and bottom of the card). On my old GTX260's and 8800GTX, that's where the memory is (I changed the coolers on them). So the card pushes the hot air from the GPU over the memory. If the card overheats, it cooks the memory. But if the test isn't using the memory then cooking the card wont re-produce the fault. I use the term 'cook' because my cards can get up to 90-100c I'm not a computer scientist but that seems like a design flaw to me. Hope my little rant helped.

I forgot to mention that they are not sandwiched, one is in the top x16 slot and the other is in the bottom x8 slot, so there is a 2 space gap between the two cards.
The cards would crash on desktop when they where sandwiched.

I'm not sure exactly which card was worse than the other with the temperatures but both companies advertise that their cards run in crossfire. So as far as I'm concerned, they are both faulty as neither of them work together. The support team at PCCG agreed with this, thats why they agreed to take both of them back rather than ask me to test them each individually and just send one back.

I would like to assume that the Gigabyte Radeon HD6970 2GB Overclocked with 'Gigabyte's Windforce 3X cooling' would have lower temperatures than the reference design. So depending on what PCCG allow me to do, I'd like to exchange them for two of those. Either that or a single 6990 but only because I would be using one, so a single 6990 should be able to handle the heat that it generates.


I have been using a XFX 6870 for awhile,I found that disabling the auto fan control for the card in the software and manually setting the fan speed to abt 55% stopped the high temps,now will not go above 60 deg.
The auto fan control does not active the fan enough,with the manual control you can set the temp to whatever you want! Hope this is some help,Doc
