amazing temps mine not reaching 83 at stock with 980mv and repast with mx-3 and nht 1
-
Mine locks up if I try gaming on 9.50V, even at the stock 680/900.

Yeah, it's known that my notebook has an electrical issue, and all this talk of bad 6970Ms has me thinking. I'm wondering if it stems from the GPU or MXM slot.

Anyway, I wouldn't even worry about it. The whole reason I started undervolting was due to some issues I had been having with my notebook. I had to undervolt it to pretty much keep it from overheating. If your temps are otherwise good it's not a big deal. It also eliminates the ability to overclock. Every overclock I have tried, even slight ones, would become unstable at anything below stock voltage. -
Thanks to OP and Kevin_Jack, at least I could solve with ATI Tray tools the idle problem described here:
http://forum.notebookreview.com/sager-clevo/589792-p170hm-x7200-6970m.html
With automatic overclocking I can run idle at 150/100 and 3D at 680/900, seems to work with powerplay...
Though I really would like to find out the reason why the 6970m idles at 250/900... even in vBios, there is no such combination, it would be 300/ 900. Must be a powerplay issue, though ít´s strange that no other person got that problem, too...
I undervolted the 3D mode to 0,91 and yes, it works, too... -
Getting amazing results here too!
Played 3 hours of Starcraft II lastnight, undervolting to .95V (clocks: 680/900)
Even on extreme settings, I had a constant 60 fps and did not go higher than 79 degrees celcius!
To compare, at default voltage (1.10), I was hitting 89 degrees at some points (mostly hit 85), but that is a HUGE difference! -
tried undervolting at .910v at stock and it freezes.
.950v, freeze,
1.000v works fine... temps are 71 for sc2 at ultra for 1 hr -
- Right-click ATT
- Hardware
- Auto overclock. Choose what profile to load when playing games, and what profile to load when exiting a gmae.
You can also create game-profiles. This works for any application. You can choose what profile to load when entering the application and what to load when exiting. This one, however, doesn't work too well with other applications that use different profiles. If you have one for movies that profile will be loaded over if you start a game with another profile.
What is the most stable 2D undervolt anyone has achieved on the 6970m?
I am currently running at 0.65V @ 100/150 with a bitcoin miner to add some load to test stability, and the card runs at a cool 45C as max, then drops to 40C~, then back up to 45 (freaking fan that keeps turning on and off - P170HM).
Gonna try lower volts, then some 3D undervolting.
EDIT: down to 0.6V on the 2D clocks now. Still stable!
EDIT2: I am starting to wonder if I actually am able to undervolt, as I am running on 0.05V according to ATT and hwmonitor. I think the laptop should have frozen ages ago due to too low voltage. -
My card idles around 47c to 48c with stock settings and whatever generic paste that was applied.
Im hoping a IC Diamond repaste will lower it some degrees more. -
I can go as low as .100v with low clock settings while watching youtube and still get the same temps as .750v, 34c lowest while idling.
-
It would appear it's only possible to adjust the voltage between 0.750V and 1.100V - everything else seems to simply not work.
Putting some load on my graphic card with the default 3D clocks results in about 70C with the fan at 100%. Lowering the voltage down to 0.950V at the same clocks and load there's a clear difference in temperature - about 5C lower temps.
As I mentioned before it appears, however, that anything lower than 0.750V does not do any difference whatsoever. Putting the card at 2D clocks at full utilization and fan @ 100% I saw no difference in temperature between 0.750V and 0.600V and down...
It's a bit sad that it doesn't seem to work to lower the voltage under 0.750V as it would result in a much cooler card when not being utilized. But it's acceptable. -
TheGreatAnonymous Notebook Consultant
Yes, you are correct, .750v is the lowest the cards will accept. It's a hard limitation, and setting it any lower is useless. There is no point in going lower anyways, as it probably wouldn't be stable. Got to have a limit somewhere, or people would be trying to set their cards to run at .0000001v.
-
can someone post a guide how to undervolt my 6970m???thx
-
Frankly I had very poor results doing this - as I had a couple hard freezes and other problems initially. Furthermore, the voltage and clocks where extremely temperamental. At the end of the day - I found undervolting not to be worth it for me (I idle in the mid 40's and go up to 85C-90C under load - typical for this card). -
-
Easy, set up ati tray tools to do "automatic overclocking" under the hardware menu. Make 2 profiles. One for 2d and one for 3d. I have mine idle at 100 core, 150 mem, at 0.8v, and the 3d profile of 680 core, 900 mem at 0.91v.
I am working on a guide specific to the 6970 at the moment.
Also, unless you modify your fan settings, you won't go below certain temps. -
-
Click the Voltage entry drop-down menu and select .80 for the voltage.
Check the box for "Include Clocks in Profile." Make sure the Core is set to 100 & Memory 150Mhz.
--> Click "Apply" --> If it's stable, click the diskette icon at the bottom to save it. Name it something useful, now you have your 2D profile. If it is stable, you may click the checkbox for "Load selected profile at start-up".
Next
Select the "..." next to the voltage drop-down, and enter 910. That translates into .910 volts. --> Select that voltage and set the clocks to 680 & core 900 memory. --> Click Apply --> If it is stable for you, click the save diskette icon and name it. This is your 3D profile.
Go to the "Auto Overclocking" menu under "Hardware" --> Check the box to enable it and select your two profiles.
Read this guide to understand the other features of Ati Tray Tools. -
edit:i done the profiles but it doesnt seem to overclock automatically.....what is wrong??
edit:i done it,ok but when i play a 1080p video the profile stays at 100 150 clocks and the video struggles to play...... -
Also, you have to change your profiles manually. I use the hotkeys: ctrl+shift+L, ctrl+shift+M, ctrl+shift+H for my low/medium/high settings -
Hi,
I registered since I am interested in following this thread.
Awesome on the find with the undervolting. How much volt would an overclocked 750Coreclock /1000 Memory clock need? I have it now on 1.1V and I am maxing 85 degrees celcius on a 3dmark 2011, Score is 3504. While on normal 760Coreclock /900 Memory Clock/ 0.910v I get 3200 (max 76 degrees).
My laptop is a 15'6 '' FULL HD - 2630QM i7 2.0 ghz / artic cooling paste / radeon 6970M 2GB DDR / 8GB Ram 1333mhz.
What do you guys think? -

@WillemWijnans
As far as voltage is concerned you're probably not going to be able to go much lower than the default 1.1v with that overclock, if anything at all. Maybe 1.05v, but that won't make any difference in temperatures. I've personally tried 1.0v with a similar overclock and immediately found out it was unstable. From my experiences increasing the core and ram clocks past the default values (especially the ram) greatly reduces the ability to undervolt. Also, hitting 85C on 3DMark11 is kind of borderline, considering that it's a pretty short benchmark and it doesn't really stress the card like actual gaming can. My advice is that if you're going to run an overclock like that look into getting a cooler (don't know if you're using max fan speed or not). High eighties and 90C+ temps has been the main reason why I just stick with the default clocks. -
its too bad i cant up the voltage on my 485m to 1.1 then i could probably get it past 30% overclock. btw with the specs in my sig and overclocked 27% on core and 23% on memory my machine gets 3897 3d marks in 3d mark 11!

Hi TGA,
I also found that the default clock with 910v just works the best.
I found that the idle 100/150mhz on .750v is not working when you are also on a extended monitor.. Does anyone know what the minimum voltage and clocks are when you use an extended laptop. I found on the internet that on bios defaults the 6970M clock to 250/900.. but it doesn't say the minimum voltage that is needed for this. TGA would you have any clue?
Regarding Fan speed:
After the temperature of the GPU hits 60 degrees, it auto starts fanning on 100% I think (making a pretty loud noise so it think it is 100%).
If I put it on 100% manually in ATI TrayTools it sets it on 100% in GPU-Z but the RPM just stays on 0-3. Is that normal?

I've never noticed my 6970M running at 250/900. Using a second monitor will increase the clocks though. Whenever I hook my notebook up to my TV via HDMI, and have both screens running at the same time, the clocks go from idle 100/150 to 300/900 (which is normally also used as the DXVA clocks when watching HD video). Only way to find out for sure what voltage is stable at particular clocks is to experiment a bit. For 250/900 I would say that you can probably go as low as .9v or so. As I mentioned before, even though the core clock is only at 250mhz, the ram is running maxed at 900, and the ram seems to be more voltage hungry than the core. Also, even though the BIOS forces higher clocks when using a second monitor, I don't think it's actually required, so you could just use Tray Tools to still force it to run at 100/150 idle clocks.
Regarding the fan speed issue, what I was referring to is the ability to press the FN+1 key. If you think the fans are loud at 60C, then you're in for a surprise. FN+1 will basically turn your laptop into a hair dryer. That key combo forces both cpu and gpu fans to run at max until you disable by pressing it again. I don't believe the fans will actually ever spin up that high by themselves, no matter what temps you reach. Also, no program that I know of reads fan speed and rpm correctly on these laptops, so you can pretty much disregard what those programs are reporting. -
i've put it at 780 1000 with 1.025v and its stable.
and my temps are(after 1 hour of full game bbc2 multyplayer)81 c
and in my room is 38 c -

Nice find with the undervolting. Wonder if the 6990 can be undervolted as well. AMD definetely went overboard with the voltage. Makes you wonder why, since heat is one of the main factors when it comes to gpus, and they would have come out better on reviews and such with a lower stock voltage.

Hi guys
I tried downvolting/overclocking my 6970m, but i encountered some strange problems
For the downvolting part, like most of you, or at least for what i have read, i can't go under 0.75V either, take it as a confirmation of what was stated before.
Now the interesting part; my problem is that i think Ati Tray tool is not working properly on my system.
I tried of lot of voltages and when i try to go as low as possible with the stock clocks something strange happen.
I can reach 680/[email protected] without any artefact on the 3D renderer and on the furmark bench.
But when i try 680/[email protected] no artefacts or anything it just crashes, i get a black screen for a few seconds, then my desktop partially comes back for a few seconds and it crashes again...
I have the same thing at 740/[email protected] it crashes at 740/[email protected] but this time i get a red screen... but still no artefacts 0.001V before, which i find really strange, going from working perfectly fine playing the witcher 2 for 1hour (740/[email protected]), to just crashing as soon as i get to 1.000V
And with ATI tray tool i can't get my memory clock to go over 945Mhz no matter what the voltage is, it crashes... i can't even get to work fine at 710/[email protected] with Ati tray tool whereas with CCC i can do it. With sapphire Trix i can even get to 800/1000 without any problems...
So i can't figure out why, why can't i get 710/100 to work with ATI tray tool, when it's perfectly stable with CCC...
Why do a 0.001V difference crashes without having any artefacts before? -

@enarth
You shouldn't use Tray Tools to set clocks that are not BIOS defaults (i.e. 100/150, 300/900, 400/900, & 680/900). Whenever I have used Tray Tools to overclock or set clocks that don't match up with any of the BIOS values (especially overclocking) it usually causes a hard crash, in which I have to hold down the power button to turn the system off. Sometimes it may work, but it's risky. Keep in mind the 6970m is rather new hardware, and Tray Tools is a very old program (last stable release over a year ago, latest version is just a beta), so it will be kind of glitchy on a newer system.
As far as the undervolting issue you should be able to go as low as .910v at 680/900 while remaining completely stable. Honestly I really don't know what to tell you as far as this, other than perhaps not every card is capable of the same level of undervolting. I believe it's the same with overclocking, some cards can withstand slightly higher clocks while others may crash. Perhaps you were unfortunate in receiving a card that won't operate properly at the lower voltages. That extra .4v will probably only net you about 2C anyways.
-
i get where you are coming from, but from what i've seen so far on many forums, there are a lot people with very similiar configurations who successfuly overclock/downvolt with ati tray tool.
They at least can make it work with the overdrive specs (710/[email protected]) which for some reasons i can't, almost everyone get to 800/[email protected] (or a lesser voltage) easily... What i'm trying to say, is that it's doesn't seem to me like it could be because my graphic card is rather new and therefore not fully supported by ATI tray tool.
I was hoping someone could tell me that it's because i forgot to check an option or missed something obvious ^^
As for the part where you point out that graphic cards behave differently, i'm aware of it, and yet i find very strange that a 0.001V could cause a crash whithout showing any signs of failure right before (artefacts, or perfomance loss)
I guess for now my only option is to use the clock that works or use saphire trix if i need the performance boost... while waiting for a new version of ati tray tool... (i don't want to flash the Vbios) -
Yeah that was a lot of seriously phoney info.
I've been overclocking with ati tray tool for years.
And it was updated last week, gets new updates regularly.
To get the latest version go to "tools and options", "general options", check for updates. It'll give you a more updated version than you can find directly.
I'm running 1.7.9.1571 -
i'm running the last one too.
Still can't get it to work properly... -
TheGreatAnonymous Notebook Consultant
@enarth
Yeah, sorry I don't have a solution for your problem.
@BenWah
You claim my info is phoney yet you offer no solution, and you certainly can't tell me how Tray Tools behaves on my own system, which my advice was based on. Also the 'latest' version is just a slight revision (still 1.7.9) and still beta, so expecting it to work flawlessly is just ignorant. -
Anyway back to the point, How much battery life did you manage to get out of this undervolt ?? ordered the p150hm with 6990m was hoping for some extra battery life!
-
TheGreatAnonymous Notebook Consultant
@ballsofsteel
I never truly tested this. A lot of the the time when I run off the battery I lock the clocks at 100/150 @ .750v, which gives me a little over 2 1/2 hours of battery life (at around 10% battery left, using default settings for W7 'Balanced' plan). Not bad for a machine like this, and you could probably manage to squeeze out more on the power saver plan. Without locking the clocks/undervolting it was usually just over 2 hours. I'm more inclined to believe the the extra battery life comes more from from locking the gpu at 100/150 rather than the undervolt, since when watching videos and such it won't clock up like it normally does. If you really pay attention you'll notice that your gpu clocks have a tendency to 'jump around' depending on what you're doing. For example, when watching YouTube mine normally goes to 300/900, but Tray Tools will force it to remain at lowest clocks until you manually change it. -

Thanks for your reply.

guys when i try to undervolt my 6970m at idle with 0.750v after 2-3 secs my screen meshed up...i need to reboot to make it right..i also tried 0.800 or 0.830 the same think happens..i use ati 11.8 drivers..can anyone help me??thx!!
-
now i have 800 1050 with 1.035v.
and its very stable!!!!!!!!
try it budys,and tell me.....
my temps are the same.80-81 at the most -
-
i try that!!
-
-
What programs can you use apart from ati try tools? I kind of dislike its layout
-
Dont mind my noobness but how do I change the voltage settings? It only allows me to go from .800 Or 1.10V and nothign inbetween? Am i doign something wrong? Im using ATi Tray tools thanks
-
I tried modifiying the bios with RBE and all works great except changing the Idle Clocks ( 100/150 ) , those remain at 0.9v whatever I do.
Though with Ati tray Tools I'm able to run all stable:
780 /1000 @ 1.025v
710/900 @ .95v
680/900 @ .91v
250/900 @ .85v
300/900 @ .85v
100/150 @ .75v
Though it does not react on the bios changes ;(
Any help? -
hmm then my 6990m must be pretty shat :/
tried UV today even 0.1 at 3D Clocks, UVD or anything like that is unstable, funny thing is when i UV my 3D Clocks from 1.1 to 1.09 even then stock 715/900 aren't stablemax speed i can get is 815/1050 it seems, i noticed that Crysis Wars with better GFX Mod is pretty demanding, on my desk Rig the most demanding game was C2 with DX11 (GTX 580)
-
I was able to push my 6970m to 850 /1100 & 810 / 1200 @ 1.1v for benchmark runs.
