I don't really know why voltage control is greyed out no matter what I do. It should be available from the start, it's a MSI app for MSI cards. The xcl command is working fine so I get exteneded core/mem clock limit but the voltage still doesn't show. I've ticked voltage related boxes in settings, tried running in kernel mode, rebooting but to no avail;/ It's not that I really need it now but I'd like it unlocked anyways. I'll probably won't bother with overvolting until I resolve my problem with load temps. Today, Witcher topped out at 67C @ 1050mhz with 65% fan RPM but it's still a tad high.

I cannot get the voltage setting to appear within ASUS GPU Tweak, seriously what am I doing wrong I don't get it. I tick overclocking range enhancement, click the advanced toggle on and off, all that does is give me "Power Target(%)" slider. Help!
Hi all,
Picked myself up a 2GB MSI 7850 Twin Frozr couple of weeks back and after sticking with the stock CCC OC's of 1050 and 1450, I decided to delve into the realm of properly overclocking it. Couldn't get AB to actually start never mind unlock settings, so jumped straight to GPU Tweak and went straight to 1200/5500 on 1.2v which ran absolutely fine in Heaven. Started to bring the voltage down back through 1.19, 1.18, 1.17 where it crashed on Heaven at 1.16 so kept at 1.17 which ran Heaven absolutely fine run after run at about 72c.
BUT as soon as I tried Crysis 2 it started crashing again with a freeze/black screen and return to desktop. Had to bump voltage back up to 1.2v before it would play properly with temps about 72c (which I did for about an hour) and it did actually crash when I exited back to desktop when I was done but I'm optimistically putting that down to something else (this was also a full system crash so no temp reading).
So I guess my dilemna and actual point is whats the best way to stability test the voltages I want to try as Heaven doesn't actually seem to be all that good? Also should I do the Crysis 2 benchmark or should I actually try playing to game to see if its stable?
Sorry for the noobishness, its my first real dive into serious GPU OCing

AFAIK, passing some loops in Heaven doesn't indicate full OC stability. It's good to run 1-2 full loops and if it passes then you can move onto testing games. I tested my 1050 OC in Heaven and it didn't crash but when I tried Witcher 2 (which is probably one of the most demanding games currently available) I got a CTD 3 times over 4 days. It happens rarely but still.
By the way, what is your ASIC because you happen to own the same card as me? I must have one of the worst 7850's ever... With an ASIC of 75,8 % it has 1,138v stock voltage and, as it seems, I can't reach 100% stability @ 1050Mhz (going by what's happening in Witcher). 1060 crashes during the end of the benchmark and 1100mhz takes a monstruous 1,180v to be stable. The card has poor temps and its fan is quite annoying above 60%. Also, what are your temps on stock and OC and @ which fan RPM value?

ASIC is 75.7%. Mine is also on 1,138v stock but was 100% stable at 1050Mhz playing everything I have for the first couple of weeks with the most extreme probably Crysis 2 Max Ed on ultra at 1680x1050. It seems stable at 1200 as well at 1,218v but I can't seem to make it stable lower than that. Idle temps are 23c at 30% and not sure about OC at idle but at load with OC was getting 72c.
Thanks for the info on Heaven!
23 at idle is freaking low
My idle temps are 30-32 C (28-29 on a cold day) and at load I got 74 on a hot day without overvolting;p Witcher 2 pushed my GPU more than Crysis 2 DX11 with hi-res textures;p I'm worried about the temps, today was quite a cold day so I maxed at 59-60 in Heaven and an absolute peak in Witcher was 67-68 @1050, everything tested in 1080p (native res of my LCD screen).

if my 7850 (msi twin frozr iii NOT power edition) has a stock voltage of 1.038, is running the card at 1.16-1.2 or even 1.225 dangerous? most of you run your cards at that voltage but most of you have stock voltages of like 1.15 for 900mhz. Is it safe for my card to run 1200mhz at 1.16v 24/7? from 900mhz and 1.038v?
If I run 1.225v I can get a bit over 1260mhz.

Hi all. this will my first post, and with a question that will be probably a bit long, and with "poor" english, but I´ll do my best to make myself be understood.
I have a Msi r7850 twin frozr 2gds, it´s normal clock speed is 900Mhz with 1200Mhz X 4 = 4800Mhz memory speed. My CPU is an i5-3350, motherboard asus p8h77-m, power unit corsair 550w 6Gigs or RAM. I have it overclocked with asus tweak utility to 1200Mhz clock speed and 5800Mhz memory speed. Its stable like it is. I´ve been reading this thread, and comparing my benchmarks with heaven 3.0 and P 3DMark11, and my scores don´t even come close to the results I´ve seen here with 7850´s.
In heaven 3.0 with 1980x1080p, Tesselation normal, Shaders high, Anisotropy 4x, Anti-aliasing 4x my "best" score was 608
In P test with 3DMark11 the score was 6541
So, nothing compared to the scores I´ve seen in here with the same benchmarks.
In Crisis 2 with full textures and everything on ultra I get no less than 47fps and hit 60fps sometimes, wich I think it´s not bad at all.
My question is, what can be the cause to so poor benchmarking with heaven and 3dmark11? I´ve downloaded all the latest drivers. (can it be an opencl.dll related problem?, I´ve tried every single solution i found on the web and
can´t make it go away. (Finaaly i solved the opencl.dll missing problem, downloaded opencl.dll version 1.2 and copyed it to system32 folder...problem fixed...but benchmark results did´t improve, so it wasn´t opencl related problem
).

Well, when the ambient temps are within the normal range it doesn't reach 70c when overclocked to 1050 with my fan profile but it is quite hot. I've never seen anyone with this card idling at 23
Also, it seems that your cooling setup is still better than mine I must find a way to put my A90 outside of this shi*ty cabinet and install a side intake fan Well, this sucks, when I bought this card I hoped for a nice and cool overclocker and was severely disappointed with both of these aspects.

http://www.3dmark.com/3dm11/4354358\I have almost 6900 there but I had 1250mhz core 1375 memory overclock...
http://www.3dmark.com/3dm11/4264803
here's with 1150 core 1375 memory
stock settings (I have the exact same card as you do, msi twin frozr III) I get about 5500 or something like that. Graphics score.
Keep in mind that some people here have Asus motherboards with LUCID VIRTU that increases score and lets them have like 8000 points, that and I've seen that motherboards themselves play a role in how fast is the gpu I've seen a test on a website once. Something that has to do with gpu-cpu latency. A motherboard had like P5000 and the worst one there had a little under 4800. Maybe just fluctuations but who knows...
BTW, anyone know what's the max safe voltage for 7850? I have 1.038v as stock, is running it at 1.2v OK? what about 1.225?
1.225 from 1.038 stock.
MSI twin frozr III R7850 non power edition
I run my MSI TFIV power edition 24/7 at 1.225V (1150, 1350) and used to run it at 1.25V (1200, 1400). I think as long as your temps are ok then your volts are ok. My temps never get above 70C in games at 1.225V. Stock voltage for me is 1.134V so slightly higher than yours but I think you should be ok as long as the cooler can handle it.
http://www.3dmark.com/3dm11/4389851
graphics score is 6581 clock 1200Mhz and memory at 1500 Mhz and 1.225v got max temp of 63º
I run 1.225 24/7 with no kind of problem

Nice. I personally had to reseat the cooler so I can get temps like yours. I recommend people to do this but be careful while doing it so you don't void your warranty. Sometimes in BF3 I get like only 46C with fans set to 100%. With fans set to 60% I do get a large jump in temps, from 45-50 to almost 60 in some intensive games.
But why don't you turn on turbo on your cpu? You could get around 8000 in cpu score I think, or more, I get around 7200 with i5 2400 with turbo on.
for me the maximum turbo is this:
when running on:
1 core: 3.8ghz
2: 3.7ghz
3: 3.7ghz
4: 3.6ghz
And you seem that you have better memory than mine, I get no increase from 1375 to 1450 or 1500, only from 1200 to 1375. In fact one time I got a weird ass BSOD from memory overclock lol. My display was full of light gray and dark gray lines.

Tried my luck again with OC'ing the MSI TFIII. Just as I thought, the card is NOT stable at 1050mhz @ stock volts. It may be good for looping heaven but in actual games I get fairly rare CTD's. Sometimes it happens after 30 minutes, sometimes it doesn't happen at all. 1100mhz core appears to be stable @ 1,180 (****load of volts for a mild overclock but it craps out @ 1,075), max temp in heaven is 72c/ auto fan profile. I can't help but think that the TFIII is not as quiet and definitely not as cool as marketed;p Hovewer, these high temps may be due to my PC's somewhat poor airflow, seeing as many of you get some really amazing temps. The card not exceeding 60 C @ 1,225v? A miracle I could easily top that on stock On Monday, I'll try to run it outside this dreaded cabinet and see whether this improves heat dissipation.

I Just fixed my problem with heaven... I´m just an jackass sometimes, Service pack wasn´t instaled, and so many corrections to win64 bit were missing, that was the problem...
My TFIII cooler in my MSI is great, 8 loops in Heaven 64º max temperature. I finally got some decent FPS in Heaven... 53.2fps with a score of 1341

I tried the new modified 12.9 beta drivers and they somewhat improve performance and, as it seems, they make my 1050 OC stable @ stock. There is a problem, though. When I was using 12.8, I had some random black artifacts/flickers (black triangles and stuff) in Witcher 2 (and some other games, but in W2 it was most prominent). This driver makes it even a bit worse. Did any of you encounter such problem with 12.8 or the 12.9 beta? If so, then is there a way to fix this?
Also, do you think It'd be a good move to swap this card for an Asus 660 DCUII? I wish I'd waited a bit longer because the 660 is now slightly cheaper than the MSI 7850 and delivers more performance out of the box (and I wouldn't have to worry about all the driver related issues). I wouldn't even think about that if the card stayed as cool and clocked as well as people say, but apparently mine doesn't Is the performance gap between a 7850 @ 1100mhz core and a 660 that big?
