GT 650m GTX 660M overclocking result database

This will be a database of your overclock's for the GT 650M and GTX 660M GK107 cores. Not interested in the system details or temps since they change from system to system but if you wish to add them go ahead. Really just looking to make a database on the clocks of the GK107.

stable at 1.325 ? really?

 

Yes like i said its bone stock and i will be posting some results after i change the bios on the card and tweek the mem timings. 100% stable and is my every day clock.


Edit. My cards max voltage for some reason is only 1.1v not 1.3. Stable at 1,350mhz right now temps are the same for the load.

 

Woah... ur lucky dude... im at 1150 on core for now... but on load i get up to 87oC... guess ill try to push it even further... the fan is not at max...

 

Well I get over 90C temps with the stock allowed +135MHz core OC on my GE60... Probably terrible stock paste job as the GPU itself can't be so crappy / unlucky.

 

Well... i cant push it any further than 1175mhz... so i keep it at 1150 core and 2800 mem...

90oC with the fan at max?

My laptop try to idle at 85-90 before the fan kicks in at 50%+

 

1390-1400 is the max i get on this card. I need more voltage after that so i'll be volt modding soon. Even at the max clocks my load temps were only 68c so there's still a little room for more voltage.

Testing out a new bios with some memory timing tweeks taking it 20mhz at a time from stock

NVIDIA GeForce GTX 660M video card benchmark result - Intel Core i7-3610QM Processor,Alienware M17xR4 score: P3374 3DMarks Not bad for a little GTX 660M on a system with 103 processes running. After i get a final set up i'll do the typical epen bench run on a fresh stripped down install and all that to max out my score but that's not bad for a daily driver.


DaCM remember the G75's cooling system is one of the best i ever seen in a laptop. You could have to much paste from the factory installed, heatsink is not seated right, I dont know much about the GE60 but your temps might be high because the gpu and cpu share the same heatpipes but i never seen the inside of the GE60 so i dont know if thats the case.

MegaBUD, this is not on manual fan turbo, but the fan was running on max pretty much constantly. Seeing that everyone has quite nice overclocking headrooms I don't think it's possible for such a bad chip to exist so it's probably because of the bad / too much factory paste.

There are design problems like small air intake area, but in general the temps of other GE60 owners I've been hearing were much lower. Of course the G75 has significantly better cooling and a larger shell, so I don't expect load temps of under 70C, but low 80s would be nice .

 

Yeah, if it's high temps then I don't think it's a bad chip. A bad chip would just crash. High temps are probably due to a poor paste job.

 

Oh... i see... well his asus laptop was 250$ more than MSI

+135 is still a good overclock... but your temps shouldnt be that high...

 

Yeah Asus is not value laptop its way overpriced for what it is. I cover this in the review and the only thing it has going for it is the cooling system.

Now i gotten some messages from some people who bought the old tech "Fermi" thinking it was Kepler and said well my GTX 670M scores higher. Well i'm happy for you its a more expensive card and yours is overclocked. The fact i got a GTX 660M to match the performance of a GTX 675M is pretty good and the $197 "Price diff. between a GTX 660M and GTX 670M are" can go to something useful like a SSD that will greatly impact performance more than the overclocking headroom you get on a GTX 675M.




Now back on topic. I would really like to see someones Max oc on a GT 650M so see how lose binning was on these because if it was as loose as Nvidia has been on some then the GT 650M would be one of the biggest bang for the bucks if it could get close to the clocks i was getting and pulling in the numbers.


Also im going to make some graphs after i get more results and publish some numbers like average oc's for the GK107 as well as how tight binning was and what makers were using higher binned chips then the others.

 

Well the gtx 670m and 675m will always perform better than a 660m... simply because they have a higher memory bandwidth...

On the positive side... its cheaper... less heat... and the power brick is a lot smaller

The 650m ddr5 is the same chip as the 660m... so they should clock the same...

Never the less the 660m (gt 640) is a great gpu for the price...

Some people can push further... some cant... right now i cant overclock higher than 1175 on core...

but after 7 hours of heavens the temps never went past 85oC... the my voltage is low... and i wont touch it... 1.1v and 1.087 with the vdrop...

And its kinda weird that MSI will prioritize the fan noise over the general temperature of the laptop... maybe theres a way to change that... well i could probably use afterburner and change the fan settings...

Also SSD wont add any fps to the game... loading might be faster but... fps will stay the same...

Ill just keep that money and buy another laptop in 2 years

 

Not really. The reason they are faster is that the GTX 670m has 24 ROP's and GTX 675M have 32 ROP's vs 16 for the GTX 660M. Stock bandwidth on the GTX 670M is 72GB/s vs my overclock pushing 88GB/s. Now the GTX 670M has a 192bit mem interface and the GTX 675M has a 256bit vs the GTX 660M's 124bit but the extra ROP's is what makes the card faster at stock clocks and why we have to overclock so much to match the performance. I found it pretty easy to hit a overclock that matches the performance of the GTX 675M despite having a smaller memory interface and way less ROP's. Those big of difference in hardware is pretty big but Kepler does a pretty good job of making up for the lack of it.


Now why SSD's dont do anything for your frame rates they do help smooth out in game lag. When your playing games with huge textures and huge expansive areas you cant instantly load every texture and some wont be loaded until you get close. I have seen this first had when you get what looks like and feels like a frame rate drop but your sitting in the upper 60's . This is from the textures lagging to load. Does not happen all the time but it does happen from time to time in some games. A nice example is World of warcraft. Fly up and start flying why looking at the ground. You will see some things as they load just pop up. When you look at this vs a mechanical drive you can see how much slower it is. Then when you raid some SSD's you can really see the power of loading those textures. People tend to overlook this in gaming systems because its never really been a issue but with games now and new games coming out SSD's will really show their speed in areas outer then a loading screen.

 

Card Maker: MSI (GE60)

Model: GTX 660m

Bios Version: Modified BIOS

Stock Core speed: 835MHz (turbo to 950MHz)

Stock Memory speed: 1250Mhz

Overclocked Core speed: 1120Mhz @ 1.0375v/1.05v*

Overclocked Memory speed: 1300Mhz @ 1.0375v/1.05v*

Are these clocks your every day use clocks?: Yes

Are these your Max Clocks?: Kind of*

*The voltages as noted above max out at 1.05v, but a GPU-Z log shows that I generally hover around 1.0375v while playing Crysis Warhead for an hour. During aforementioned GPU-Z log, I was running at 1140/1300 clocks, and was perfectly stable. However, another game, Stellar Impact had occasional crashes, so I bumped the clocks to 1120/1300 and I've had no issues since.

More info on my tests, benchmarks, and temperatures are on this thread.

And it's also noticeably thicker and heavier than the GE60. The Asus's fatness (or phatness) gives it better cooling potential.

 

Well after 7hours of Guildwars 2... the driver crashed... looks like 1150 core is too much... or i could try again without overclocking my memory... kinda sad...

 

Chances are the oc is fine and its just a issue with guild wars 2 being new

 

Yep, it would be strange for it to run fine for 7 hours and crash after. If the OC is too high it would crash in under an hour imo.

 

Well... the game would crash... not the driver.. no? i moved it to 1125... see what gonna happen tonight...

The gpu perform well... we just need better driver and that would be perfect... too bad optimus is buggy with the latest beta driver

 

I have a Y580 with GTX 660m.
It was my first time OC'ing and I had +135 Core / 300+ memory.
I don't know what I did but I saw an artifact and I am not sure if I was adding to the OC everytime I hit apply in MSI afterburner.

 

No it only sets the clocks one time. The GTX 660m should handle +135 on the core pretty easy. But dapending on the memory used 300 can be pushing it for some of the cheaper ic's.

Artifacts are from clocks set to high "usually memory" or heat. What are your idle and load temps? You might want to try backingoff your memory clocks to about +150 then test in 10-20mhz increases till you get artifacts then back off the clocks 10-20mhz.

 

I usually set it on MSI AB to 135 Core/300Mem

I see, so every time I turn on the computer I have to set the over clock again to what I set it above? And it can only be set 1 time per boot or can I clock it back to normal?

Is this safe to run everyday when I play BF3? What's the max temp a GPU like ours can take? 70C too high?
Idle it's at 40C. I also have a homemade fan by my vent sucking air out as well as a laptop cooler notepal slim. BF3 I can get about 35FPS ultra. Core 135+ memory + 300.

GPU-Z is showing 970 GPU Clock, 1250mhz to the memory boost 1085. Despite this, I don't see it OC'd on GPU-Z though... or at least doesn't appear to be. What do you think?

On afterburner I put 135+ GPU Clock and 300+ memory. I can run ULTRA on EVERYTHING in BF3 and get 50+ FPS consistently 64 player server w/explosions etc. WOW does not top 70C (without fans) with fan its 68C.

What actually raises the FPS in games like BF3? memory or core OC'ing?
I don't want to damage anything I heard others are going way higher though. I have Lenovo Y580.

Is there any damage that can be done?
Since I already overclocked it, has anything changed with my 660m? I just reallyt care about my GPU its why i have the y580(affordable gaming)

 

I've repasted my GE60 with Arctic Cooling MX-4 (it was my first laptop pasting ever, so it probably isn't the best quality) and my CPU load temps dropped by 10-15C (I'm getting around 80C now). The GPU is running cooler too, but now I'm starting to get the same thing as MegaBUD: the fan pretty much never gets to max speed, probably because the CPU heat is not enough for it to step up now.

Edit: a 10 min Furmark test maxed out at 85C after about 5 minutes. Got 93C before the repaste while gaming once, so definite improvement here too.

 

hello, sorry if it's a wrong place for my question.

i'm getting gt 650m running at high idle clocks according to gpu-z and hwinfo64. they are 1670 mhz for shader, 835 for geometry and 900 for memory. this is when no program is utilizing the nvidia gpu. as soon i start some program on gt 650m, clocks might go even higher under load but then, if there's no load again, with the program still running, they would throttle down to lowest, like 135 mhz. should i close that program running on nvidia, the readings would immediately jump up and stick there.

is this normal or something is wrong?

 

I have my 660m overclocked to 1200/2700 with nvidia inspector, scored p3248 on 3dmark11. Kombustor stress test won't get above 78 degrees and haven't seen Far Cry 3 go above 64, but I didn't have my meters on longer than an hour and a half or so.

 

With nVidia Inspector my computer loads at whatever I left it in, but I also forced the state at one point. Now I just use a couple of the shortcuts I have to go between idling and high clocks. And my battery levels I keep low

 

It's a combination of ROP's and bandwidth. Bandwidth will allow it to maintain higher FPS at higher resolution while more ROP's will improve FPS generally, but to whatever resolution is a bottleneck due to the bus width. 128-bit cards are pretty much restricted to 1600x900 or lower.

Very few games rely on the hard drive or SSD for streaming textures. Games like World of Warcaraft may benefit somewhat, but if you have a decent amount of fast vRAM (like 1GB GDDR5 is all needed really for 1080p) it won't make a lick of difference. Pretty much every other game out there it won't matter at all other than faster level loading times.

 

Been using +135 core and +300memory 8 hours a night 4 nights a week since this summer and the machine run perfectly without any hiccup...

Only problem i have is the stupid hard drive that "click" everytime it goes idle... and the weird performance i get on my msata SSD (trying to fix this one)...


But game wise... this machine is a beast... at 1200$ (now a lot less) im very happy...


And for the whole 660m vs 670m fight... the upgrade cost doesnt worth it. My friend went with an Asus sure he gets higher fps but to be honest... i dont really see the difference between 45fps and 60fps... and i can use that saved money on a SSD or keep it for a next gen laptop.

 

anyone can email/sendspace me the 660M vbios ( 80.07.2C.00.12) from Asus ?
i just brick my one with mod vbios and want to back to original.

 

Thanks for this. I haven't bothered OC'ing my 660M yet so I'll start with this. Playing Bioshock Infinite right now it runs well, I think there's in game optimization issues with some bad stutters but overall runs well on laptop. Beautiful on the desktop.

 

Hey guys, I have a question. I have the g46vw, and I oc'ed to p5 gpu clock 850mhz,and mem clock 1050mhz. Then, on p0, I did +135 for gpu, and +300mhz for mem. I'm hitting 82 degrees C for max, and 80 C for average for stress testing. Then on games, I get 60 C max on regular games, then 70 C on really demanding games. Is that a bad temperature?

 

NVIDIA GeForce GTX 660M video card benchmark result - Intel Core i7-3610QM Processor,ASUSTeK COMPUTER INC. G75VW score: P3802 3DMarks

 

That temperatures are OK. I am getting 84-86°C while playing a demanding game.
Dangerous temps start at around 90°C but then your GPU will automatically throttle its clock.

 

That's a fantastic score!

 

Super late reply, but that's my score, not his, lol.

 

Ha, my apologies, but the posted link had no further info so I had no idea.... regardless, awesome score!! Very impressed for a 660m as a fellow owner! :thumbsup:

Curious, why is he posting your results ha?

 

What ho? A GT 650M overclocking thread?

Challenge accepted!

Right off to do some benchmarking. I'll be back...

 

Any idea where I can find the actual temperature the throttling starts at? I've ready so many different things i don't know what to believe.

My MSI GE60-ONC with a 650m runs in the low 80s before overclocking...in my house with temps of 75ish degrees at work it seems to hit around 81 before overclock. Running a bench at work right now which is around 65 degrees ambient and 87C was my max with furmark


Just finished 2 furmark burnin tests

650m
GPU Core: 1060MHz, Memory: 3000mhz, 86C
GPU Core 1101MHz, Memory: 3000mhz, 87C

Going to move up in 10mhz increments now.

Any idea if i move up in core clock and crash, will reducing the memory possibly help or if I've already tested @ 3000mhz memory does that mean 3000 should be fine?

Thanks all

 

@chiznitz Reducing memory to 2500-2600 for everyday basis in not just recommended but it can add +10-20 mhz core overclock. You don't want to have fried vRAM, don't you? And even though I have seen too many people who OCed memory to 3000 I will never do that. 2750 is the highest for me and I set it for benchmarks only.

 

Ok thanks for the tip I'll move it down to 2500.

Any idea why kombuster and furmark both say things like 1110mhz (Throttling: -750)?

Pretty much says this as soon as I start the test and never goes away.

 

That thing about throttling may mean something but for my laptop it means nothing Who knows.

 

Nvidia stills sells the 650M. They just overclocked it and called it the 755M

 

No 740M.

 

Can we expect the 830M to be the same card?

 

As well as 825, 820, 815 and 810... just clocked differently

 

Well, this this sums up my reaction quite nicely.

(explicit language)

 

So here is what I am running into.

@ + 227 core 3dmark11 Demo runs fine
@ +228 core 3dmark11 demo errors out.

Ram is set to +550

I was able to run furmark @ + 276 core which is significantly better .... Do I just say, since 3dmark can't do it that my final overclock for now should be +227 core, and if this runs stable in a longer test i should keep it?

What is max safe value for ram that would be recommended?


Also last night when playing CS:GO I was overclocked to around +276 and +1000 on ram. I noticed once in awhile I would get a stutter in the game and wasn't able to determine the cause. Could having the vram clocked to high cause this or is that most likely something else?

 

I'm just figuring this stuff out...barely. But I have a question. I have a GT 650m and am wondering how do you go above the +135mhz boost for the gpu clock. I've tried with Nvidia Inspector, MSI Afterburner and the EGVA Precision X and all 3 have it capped at +135. I have been running the +135 setting for a gpu clock of 969mhz and a memory boost of 1135mhz for a memory clock of 3135mhz and everything is running very smoothly with max temps in the mid 70's. Just wondering what I'm missing to be able to push the GPU a lil further to see what it maxes out at. Thanks for any advice.

 

With Nvidia Inspector you can go over +135 on some driver versions, but it is a simpler solution to flash a modded BIOS to your laptop (if there is one available) which simply unlocks the sliders in all the programs you mentioned.
For the Nvidia Inspector method you have to create some batch files with commands to force the GPU into a state, which you set to be overclocked. More info here: http://forum.notebookreview.com/gam...guide-workaround-max-clocks-oc-stability.html

 

Thanks DaCM. I had to do some homework on creating a batch file and how to make it work pertaining to this issue. It was a lot easier than I though it would be and it worked great. Was able to run Need for Speed Rivals last night with no problems at 1150 for the gpu and 3100 on the memory, what a difference over stock. Afterwards I tried the 3D Mark 11 for a score of P3006.
Oh, ThrottleStop helped a lot also. My Dv6t is known for not hanging around full clock for very long.

 

I have a MSI GE60 i760M281FD
running at:

Core +135Mhz
Memory +50Mhz

Im using the HWBOT Unigine Heaven Extreme Preset Benchmark and i get 625Points with it.

My Temps go up to 94C° then the gpu automatically throttle the core to 915Mhz or 835Mhz till its less then 90C° then the GPU OC again to +135Mhz etc.

i think i will replace the paste on the chip with my Mx-2 lets see if it can do better job... if not ill get a hydro metal paste.
