Overclocking 760M GTX

Helloo guys i wanted hear your opinion about overclocking a 760M GTX on acer v3 772g notebook.I know acer isnt that good in temperature like MSI or some other brands but its not also bad like some HP and lenovo models.Im definetly thinking to buy a cooler pad to solve a bit that problem.Does the cooler pad affect CPU and gpu or just cpu temperature??Can you recommended me a good cooler for my model cause i dont know whats best(active cooler or passive or multi?) and finally could i achieve the performances of a 765M or maybe 770m?by overclocking my gpu?its the same chip just with higher clock...so could i safetly overclock it to a clock of 765M without to be worry about my gpu and temperature?Im new to overclocking so any advice is a good one..I know it voids the warranty but they will never find this out even if the gpu overburns which ofc i wouldnt like but i guess its so

 

OC per little amount of MHz's and then play, watch temps..

 

You should probably get an active cooling pad if you are looking to overclock it to get performance near a 765m. I doubt you could go that high though. But you are correct. If you do get up to 850MHz on that, your performance would be similar to a 765m. You wouldn't be able to do as good as a 770m though. They are different chips. The 760m/765m one SMX less than the 770m. I've used this before and I know someone that does and he says good things about it.

Remember to do what sasuke256 suggested. Don't bump by 100 MHz. Go in small increments - I always do 20.

 

Okay so active cooler is best...what is the normal temp which i shouldnt surpass for GPU?so basically whats the limit for safe overclocking?i dont wanted to push it too high..i will try just to reach 765M clock..will the overclock affect also cpu temperature a bit?whats the limit for cpu temperature?i played a bit today on my brother laptop and i measured max 100 celsius for gpu and around 92 for cpu and its lagging more when temp is over 90 for cpu and 95 for gpu..its a old notebook just wanted to try out a bit

 

well if your temps are already 90° then you dont have a lot of margin..

 

No no..thats my brothers notebook..he has a old hp...im generally asking about temperature limit for cpu and gpu for stable overclocking..How to test the system after overclocking?by playing some demanding games?or?i read on notebookcheck about a stress test but whats the name of the program and is it better for testing than gta 4 and other demanding games

 

HWmonitor is the best monitoring program, try to play bf4 beta or a demanding game @stock and then post the temps here

 

The stress test is furmark. It basically runs yours shaders (they are usually what work the hardest in your games and their hardware outputs the most heat) for a long time and at full capacity. I prefer playing a game rather than running furmark. I wouldn't play BF4. It does not really exploit parallelism in the CPU well considering it is still in beta and you could be CPU bottlenecked. Try something like Bioshock Inf or Crysis 3.

 

Thank you..You both seem to know a lot about overclocking...I will buy myself battelfield 4 and crysis 3 in three weeks cause i have to study now for college ...do you have skype or email?i could use help from both of you for overclocking...P.S did you read watch dogs requirements?2.6ghz quad and 6Gb Ram as minimum...would i notice improvement in games if i add another 8gb ram so i would have 16GB ram or this is useless and just for multitasking?

 

DON'T USE FURMARK, MSI AFTERBURNER, OR OCCT FOR STRESS TESTING YOUR GPU TO DETERMINE OVERCLOCKING STABILITY.

OK I'm done yelling. Seriously, these programs are just power viruses designed to heat up your GPU as much as possible by running a bunch of synthetic calculations that have absolutely no bearing on real-world stability in actual games. You're more likely to damage the GPU than anything else running these things. They are all OpenGL-based (except OCCT) and 99.99% of games out there are Direct3D. The only thing I think they might be useful for is diagnosing overheating issues, but frankly there are better programs out there for that, such as Unigine Heaven.

I stick to Heaven for all my GPU stability testing because it's based on a real D3D11 game engine and is as close to a real-world game test as you can get without having to find an actual game to test. Games which have looping timedemos or built-in benchmarks, e.g. Hitman Absolution and BioShock Infinite, are also good tests, but because Heaven pushes the GPU so hard, especially when Extreme Tessellation and 8X MSAA are turned on, that I find it will crash an overclock that is stable even in games. Using FurMark, I can run overclocks that are 50-100 MHz higher than what would be stable in Heaven, which tells you just how useless those tests are.

 

If you want to run a synthetic GPU torture test, I think MSI Kombustor is the best, but it's really not indicative of real gaming temps. I agree with octiceps on this. Heaven, Valley, even Catzilla/Allbenchmark are better stress tests.

 

Yeah Catzilla is supposed to be quite brutal and representative of games. I haven't had the chance the test it out yet. I tried Unigine Valley before and found that it wasn't as stressful as Heaven, so I've stuck with Heaven. One of the nice things about these programs is that they are actually easy on the eyes when testing with them. I mean, who wants to spend an afternoon of overclocking and benchmarking staring at the same furry donut for hours on end? As for me, I'll take the magical tour through a kingdom in the sky or watch a giant cat destroy a city with laser eyes any day of the week.

 

Octiceps did you overclock your 650M SLI?what temperatures you got in heaven?650M sli non OC already gives a lot heat and its big risk to overclock it...i wanted to buy y500 sli but its end of life..they deliver now just the model with i5

 

Actually my 650M SLI is quite cool. I've overclocked it from 790/2000 at stock to 1120/2250 without increasing voltage. I can loop Heaven at max settings for hours without exceeding 80C on either GPU.

 

What temperatures you got in heaven on your 650M SLI?do you use a cooler pad?650M SLI NON OC already heats a lot..thats why im interested about the temp of yours gpu and cpu

 

Oh i thought it wasnt delivered...do you use a cooling pad?suggest me a good one?

 

Do you increase paralel both parameters like 810/2020 or this first the parameter till a point and than second?describe a bit that...which program you used for overclocking?

 

There are a million overclocking guides out there, Google it.

I use MSI Afterburner. I increased core clock first until I found my maximum then increased memory clock while keeping core overclocked.

 

Octiceps have you tryied battelfield 4 on your system???can you play it on high on 1080p?i hope i will get 30fps on medium/high

 

Yeah I've played the beta. I get 40-50 FPS at 1080p Auto settings which is everything on High and MSAA turned off. I like to play with as close to 60 FPS as possible at all times so I've turned a bunch of settings to Medium or off but left textures at High and AF at Ultra. It still looks decent but plays a lot smoother and more responsive. Graphics in BF3 are better and it runs way better as well. I average 70 FPS at 1080p High/Ultra in BF3 64-player multiplayer. Not that any of this matters as I'm almost certainly not getting BF4 at all, unless it's part of another Humble Origin Bundle and costs $5 or something.

 

Any updates on the subject i'm curious to know how you can bump the freq. up with the V3 772G

 

Bump up

 

sorry sasuke i was absent cause i had to learn but im now back and i still havent overclocked it but i made a test with kombustors and heaven engine..i will insert the images
1.the settings in heaven were directx11 quality:ultra tesselation:extreme 3D:disabled anti aliasing:8x and resolution 1920x1080..so i guess thats max.
2.kombustor 1920x1080 msaa 8x and i didnt know what to check and i clicked GF OF TEST(GL4) run stress test(settings panel)

 

and this is for Heaven...I made test for around 12 and half minutes for both benchmark tools..kombustor stresses a bit more my for 3-4 celsius and the cpu also is hotter..it hits 72 max but usually its about 69-70

 

i downloaded also msi afterburner latest version from official site but it doesnt shows me frequency like i saw on few youtube videos???so how much room i have to overclock my 760m?these testes were done without my cooler pad!!!!i just want to know how much can i overclock safe without to use my cooling pad..i read that a guy on some other site said that acer clockdown 760m to 627mhz from 675 default but i cant see the main frequency thats why i dont know if its real 627mhz starting frequency

 

im completly newbie on overclocking so im really careful be less harsh for my poor english i try my best always

 

well the 7xxmhz is the turbo frequency that's why you got 672Mhz as a start point
for the kepler cards, you can add +135MHz to the core (and + 300MHz to the mem in avg.) without any problem, so add the 135MHz by taking the slider to the right and the card will go to 7xx+135MHz when in 3D mode
(you can test with gpu-z if the freq goes up or not )

 

yes i understand that but i think that this starting frequency is 627mhz but it goes up to 718.5mhz like on the kombuster picture...but why my msi afterburner doesnt gives me exact frequency?i can just push from 0 to max 135 core clock and memory clock from 0 to 1000...its not like other user which i saw on youtube????the have listed the exact frequency of the card and than they push for more if they want...look at the last picture you will see what i mean?what about shader clock?i seen some overclocking this also this but i cant change nothing in shader clock

 

i will try to push 135core and 300mhz for memory..im going to put a picture after 10minutes in kombustor..so will a game like crysis 3 or some other demanding game cause more heat than kombustor??

 

do you think also that bigger notebooks..mine is 17"3 have less heat problems cause of more space between components than 15"6 or less?or it doesnt matters?

 

seems good or???it seems i shouldnt worry about gpu it hit max 58?the cpu is what i should worry about it hit 78 but its usually way under that..normally all cores are 55-65 but it hit once for a few moments 78..that why it shows 78..i put 135mhz max fore core(which is max allowed) and 295mhz for memory...maybe its now on level with a 765m?though as far i saw 765m has starting frequency of 797mhz mine is now 763mhz but it have more memory 1150mhz vs 1102
here a link of standard version of these cards Nvidia GeForce GTX 765M compare Nvidia GeForce GTX 760M GPU

 

indeed, it's at the level of the gtx 765M congrats you can test with 3dmark 11 the temps to be sure (cpu+gpu) cause kombustor only stresses the gpu

 

sasuke is it possible that new drivers change my overclock settings???i didnt touched mis afterburner after that but i played a bit crysis 3 and battlefield 3(maybe both half hour) and i noticed that my notebook was much warmer than before...i thought maybe that it was running on integrated graphics cause my fps was really low on battlefield even at 768p...than i open msi afterburner i saw that the memory clock went to 1000?????core clock was 135mhz like before but memory instead 295 went to 1000...and all i did today is that i removed old drivers and put new ones from nvidia???could it be cause of that???i hope nothing is broken inside ...i run benchmark test and it seems now fine when i lowered to 295mhz memory clock..but im interested how is this possible?that it byself overclocks the memory clock to 1000mhz??ever happened to you???

 

Try to see if you are in high performance power plan when you game, seems like you are on power saver mode

 

I was on balanced mode and i change that to high performance and than battlefield went good but after that i saw that the memory clock went +1000mhz istead 295..it seems that the clu didnt hit 99/100C To shut down immediately..maybe i have luck and nothing is broken inside cause i noticed that after 10-15min playing time in crysis

 

rollback drivers and test again !

 

no everything is fine with new drivers just i was scared that something is broken but i adjusted manually the memory clock again...i see you are in february buying a new notebook..i think that you should go for clevo/sager..choose the one which has a exchangable graphic card...i think P150sm?something like that..and few other models also have that option

 

Thanks for the answer but the budget do not allow the 150EM..
Too expensive.. The gtx 765m is the best i can get with this budget..

 

If you had to choose between those two, I would get the MSI. 770M is much faster than 765M. Pretty sure the GPU in the MSI is also upgradable if you ever decide to go that route.

 

Still the msi overheat like hell in cold countries 95deg c for the cpu ! And this is for -10deg c ! We got here 35/40deg in the summer !
I would have to try to find cpu thermal paste which is unavailable in my country.

 

Where did you see that MSI CPUs overheat? That isn't true. If you're talking about the Anandtech review, they've already acknowledged that they got a bad laptop.

Also, I don't think we should consider Clevo laptops upgradeable anymore. It seems like they've destroyed that part of their legacy. Only Alienware and MSI are leaving their systems open to future GPUs.

 

notebookcheck.net test of the GT70 2OC and youtube channel of an owner, he said 95°c without turbo cooler, which is unbeleivable, all arround the net i'm seeing the msi laptops working just under the bar of thermal shutdown 90-95° (without being ic diamond modded of course )

 

Where did you see that? What I read was that they received additional review samples from MSI and they all suffered from the same overheating.

 

Prema from Tech Inferno managed to get a GTX780 to work in a P150EM, so there is a ray of hope for Clevo owners. LONG LIVE PREMA! :thumbsup:

8970M also works in P1x0EM Clevos.

 

@OP: any updates on your quest to overclock the 760M? I have the same graphics processor myself (Clevo W370SK), and I am finding ways to overclock it past the 135MHz OC limit available through nvidiaInspector and Afterburner. It runs cool even overclocked, so I figured it wouldn't hurt much to push it even further, if possible.

 

You need a modded bios to oc past the +135mhz limit..

 

sasuke do you know why i get on gta 4 on benchmark average of 45-46 fps with everything on max(even view distance 100 and all other to 100 except vsync is off) but in game with these settings i get around 17-18fps????is this maybe cause its using my integrated card..even on benchmarrk 760M isnt listed..its intel card listed????i read on some forum they say that the benchmark is old and its not made for 1080p resolution when the game came out???

 

look at this video..allmost same components(has a slightly better cpu) and gets 50-90fps with everythiing on max in gta 4..seems its not using my 760m gtx at all
Asus G750 - GTX 765m - Gta IV , Crysis 2 ( Maxed out test ) - YouTube

 

@sasuke256: thanks for the info. I guess Svet's vBios Tuner is the only way, then..

@Beowulf112: I have GTA4 on my machine, and it turns out the benchmark always produces higher fps than in-game (higher by around 20fps). Granted, with everything maxed out on mine, I get an average of around 35fps in-game (morning, with a bajillion vehicles spawning all around) on stock graphics clocks. If it's night in-game, the fps increases by around 10. Also, when I benchmark, gta 4 always lists the intel hd 4600 as the graphics processor, which I'm quite sure is not the case.
There are a couple of reasons I can think of why the Asus G750 produces those high framerates:
- he's using a 765m, which I think can produce 5-10 fps more than a 760m
- he's recording when the game is at night, and the place is not conducive to a lot of vehicles spawning which can greatly reduce fps
- he maybe using a different version of the game (I hear 1.0.4.0 is the best fps-wise), or that he may have installed some mods that increase the efficiency of the rendering (not sure if this is possible)

Regarding your case, you might want to use a program that logs your graphics (and CPU) clocks, like nvidiaInspector, and check the results after playing, since it looks like your graphics and/or CPU is throttling. I can never really get to load gta4 if I force it to use the iGPU, so I don't know what the framerate would be like on the iGPU. But I think it is highly unlikely that the iGPU can produce 17-18fps in-game with all settings maxed out, 5-10fps is a more realistic value.

 

you know whats funny..in the save house at beggining it goes to 50-60 and when i exit the door just it drops below 20..actually i overclocked my 760 and its similar to 765m now...sasuke maybe know the solution
