Yes it does - thats what the VDDC readings are. It maybe that it does not yet recognise 69xx - but VRM temps are a core function so doubt it will be long before it does for 69xx. EDIT: Had a ferret over at GPU-Z, there is a hot-fix to add 6950 & 6970 support, came out 11 Dec and will be added formally on next release. GPU-Z 6950 & 6970 Support - New exe file download Regards Zy Thanks mate. Here is the temps on 2x6970 crossfired at a constant room temperature of 25C running at 950 core & +20 power tune on both cores. The 1st gpu core=72C, VRM=80C. 2nd gpu core=64C,VRM=77C.

(Message 45323) Posted 26 Dec 2010 by Arif Mert Kapicioglu Post: Keep an eye on VRM temperatures, they often get missed/forgotten about in the concern over Core temperature. Its the VRMs that cause 5970s incorrectly handled to burn out, as there is a very wide difference between core temps and VRM temperatures on a 5970. The 5970s have an inherent design issue that causes this, but does bare watching for in a 6970 (and upcoming 6990) until it becomes clear what the situation with the new design is. I have no idea what the VRM temp way points are for a 6970, but for a 5970 they are: Up to 100 degrees - ideal, usually core temps are around 75-80 Up to 110 degrees - tolerable, will be fine, watch for increases, core temps usually around 85-90 Up to 115 degrees - pushing your luck, need to back off, core temps usually 90+ 115-120 degree - card life will drastically reduce, must cool further 120+ - card devolts, will burn out fairly quickly if run 7x24 at these temps GPU-Z is a good one to use to monitor VRMs as well as core temps Regards Zy The current GPU-Z doesn't show VRM temps. Therefore, the other variables are my only guide here:(. The question is that will it be possible to run 4x6970 with stock speeds of 880? Well, you will definitely need a cool room for that and considering these temps, i dont think a room temperature will be enough. Does anyone have any heat issues with 6970 crossfire?

(Message 45321) Posted 26 Dec 2010 by Arif Mert Kapicioglu Post: i uped the power to +20% and the times reduced by about 1/3rd... from 2 and 3 min to 1:12 and 1:50 for each type of WU. I will overclock it later and see what it can do. you can see info on the powerTune here: http://www.anandtech.com/show/4061/amds-radeon-hd-6970-radeon-hd-6950/7 Are you running crossfire? I couldn't see the host in your data. I just lowered the core to 850 and memory to 685 via MSI Afterburner Beta 5 and still the temps are really high on the second one, easily exceeding 95 degree. I will check the temps tomorrow at a constant cooled temperature of 25. Hope they wont exceed 80:(

At +%20 power and 880 core clock, here is my host, you can check the results. I know the times are already posted by other people. You can check also mine. Hope will help. Take care http://milkyway.cs.rpi.edu/milkyway/results.php?hostid=248968&offset=0&show_names=0&state=2 For 880 core clock, i learned that power tune should be at 0 (am i right?), however i increased the power tune to +%20 and core clock to 950. If anybody understands the power tune option, please advice me for what to do at stock core clock and 950 core to save heat. The max temp is 80C at 880 core, 85C at 950 core. (The value that writes on GPU Temp. #2 on GPU-Z)

47) Message boards : Number crunching : Upcoming Cayman architecture. (Message 45046) Posted 15 Dec 2010 by Arif Mert Kapicioglu Post: saying frankly, I was really expected way more we've got. I really disappointed... The only thing is that i got 4870 and 4890 in hands and I desperately need to move forward. But now I'm confused - what should I do. I wanna wait results of 6970 crunching on MW in order to make decision with open mind and reliable data in hands... Guy who will get 6970 in hands, pls post your results here ;) I'm waiting for shipments to arrive my country. Hopefully next week, i will have them and will let you guys know the results.

I choose to take it as a smack at amd and I think it deserved. per amd the 6990 might not be out until q2 2011. ridiculous. besides, I have seen numerous release dates for the 6970 and just read of another, 13 dec. I hope you are not the dude and your post a typo, not a smack, and the cards on the shelves tomorrow. goodygumdrops. I meant the December 8. Anyone with a logic could understand that. The source is very reliable and just wait for the tomorrow and you'll see. anyone with logic? understand? oh mercy. ok, so you fat fingered november vs december? no biggy. but I believe nov8 was one of many posed release dates, and logic is certainly intertwined in my response considering what is understood therein. frankly, logic is it at the core of my response that and a touch of humor. as I said, I hope you are correct though I am more interested in the 6990. EDIT: I somehow missed your white russian addition. I hope you understand I was having fun. joking in forums has bitten me several times. anyway, the dude abides. :) No problem mate:)

54) Message boards : Number crunching : 5970 Safe VRM Temperature (Message 44408) Posted 28 Nov 2010 by Arif Mert Kapicioglu Post: I am running 2 wu's on each core and I have found all these settings to be a bit nebulous as all my cards act differently. I'm far from any expert, I just experiment and check the results and I haven't had anything fail yet except 1 fan. My room has an open window letting in -30C airflow. That helps, yes. -30C airflow!!:) Are you living in north pole? That is one favorable temperature for oc:)
55) Message boards : Number crunching : 5970 Safe VRM Temperature (Message 44405) Posted 28 Nov 2010 by Arif Mert Kapicioglu Post: I have had two of my 5970's running @ 950 core 1000mhz memory and I am seeing temps@ VDDC 109,114,114 and it's been running for days 24/7. My fan is set at 100% (I don't mind,lol) and GPU temps are @ 66,67,84,85 I have cards waiting if she blows so will let you know but as of yet for a long time I have been running with these numbers and oh yeah 1200mV. Oh, I do adjust one core to 910(or any little different number) to keep it running smooth (it wants to oscuillate back n forth 2d,3d@950 for some reason)and I have seen sustained temps around VDDC 120 and so far she is still crunching. You can see the results by graphing my current challenge performance these last few days. Would you state the working environment? My hosts work at a room cooled to continuous 25C. How did you oc those 2x5970 to 950 core? Also i checked your host and despite all that high clock, your wus take long time to complete. Are you sure running only milkyway@home?
56) Message boards : Number crunching : 5970 Safe VRM Temperature (Message 44403) Posted 28 Nov 2010 by Arif Mert Kapicioglu Post: My 5970 is currently at 941MHz core clock and 1000MHz memory. Via GPU-Z my VRMs are around 95°C. I have altered the fan profile via MSI Afterburner and the GPU's are at 66°C & 76°C, but the fan is at 80% and noisy. Maybe you can push yours a little harder? I have 2x5970 running crossfirex and there are no slots between them. Therefore the first gpus vrm is this high (110). Otherwise, i would oc them more. By CCC i suggest you to reduce the memory clock to lowest official value which is 500 mhz, if you only use the 5970 for milkyway. It will save you heat and power
57) Message boards : Number crunching : 5970 Safe VRM Temperature (Message 44397) Posted 28 Nov 2010 by Arif Mert Kapicioglu Post: Thank you Zydor. My VRMs are currently at 96 and i will push them 30-40 mhz more. Just below 105 degree. Actually, oc them to 850 which is the default 5870 clock speed and the vrm is 110 degree. I wont push it further.

60) Message boards : Number crunching : 5970 Safe VRM Temperature (Message 44374) Posted 27 Nov 2010 by Arif Mert Kapicioglu Post: Hello all, I haven't been able to get a straight answer on max safe vrm temperatures for 5970s. Some say stay under 100 and some other say under 120 degree, for 24/7 usage. I want to get max out of my cards. If you have a good answer, please tell me so that i can tweak accordingly.
