gtx670m overclocking possible??

is it possible to overclock gtx670m into gtx675m and get the same performance? is there a certain max temps at max load the gtx670m should have in order to be able to be overclocked? this is on a clevo btw

 

The 670m is already a 570m with higher clocks. I 3DMark11 scores of the two differ by 1000 points. That architecture is going to have trouble dissipating enough heat while trying to increase by almost 30%. Even if you do get to the same clock speeds, the 570m was based on the 550Ti IIRC and the 580m was based on the 560Ti.

 

omg what a freaking scam , why it wasnt named gtx575m instead , they fooled me into believing i got a cutting edge gtx 6xx series , curse you nvidia.

 

The 675m still has the third highest single GPU 3DMark11 scores. It is by no means old (actually exactly a year today since it was announced). A year may sound like a long time but for the flagship for the last gen, it is not. Also, for the price it is a pretty good deal.

 

chuckles 87 if you read any of my posts you will see that I lol at people who buy extreme power consuming gpu's like 670m or 675m. 660m on some cases like dx11 games goes toe to toe with 670m.

This new 600m series is quite funny. 660m barely takes any power compared to 670m. The new 680m takes less power then your 670m and is twice as fast.

660m takes hardly any power. I reckon nvidia have done well as a company to get rid of 2010 tech in mid 2012. More funny is people have been brainwashed thinking it performs better then kepler card get that as it is faster but it has no features. 660m and 670m are so close to performance that if you get a 660m and oc it 10% you should get better performance then 670m in virtually everything.

People like maverick make me laugh. 675m is simply put a 2010 fermi 40nm card revised and revised. Its like getting maverick1989 7970m revised 28nm card in january 2015 for top money.

Anyway main point is your 670m oc'd won't go far as nvidia cranked as much as they can. 660m though is barely anywhere near its limit.

 

so overclocking gtx670m isnt possible?

 

It is like most cards. Just that there is not much room for oc'ing or no real point and it depends on your psu.

 

anyone with experience with ocing gtx670m, how much extra performance can you squeeze comfortably?

 

chuckles at the end of the day it is your decision. If you DO read any of this guy's posts, you will see that almost everywhere, me and many others are telling him to get some sense. 1 vs 3-4 most times is not a very hard decision for me to make but it is your call. I would suggest you ask others before deciding.

That being said, as much as I hate to agree with nissan here, I have to. The 660m would, imo, be a better option than the 670m at this stage. On the other hand, THAT being said, the 675m (if the laptop you are purchasing has the option to upgrade) would be a much better option than both of them. If you get the 7970m, that is the best option but, again, that depends on if your laptop has that option.

Nissan, do not come back with some lame stuff about power and what not. Keep that out of this thread. A guy is asking for help. Keep it at that. Your post was only helpful until you told him the 660m was better. Everything else was a bunch of nonsense. KEEP THAT OUT OF THIS AND OTHER SUCH POSTS.

 

570M GTX could be overvolted to get an extremely high overclock and still not overheat, while pulling FPS similar to the 580M GTX at stock. I wouldn't doubt it if the 670M GTX were the same, considering it is the same chip as the 570M GTX.

Complete nonsense, welcome to my ignore list. I've had enough of your ridiculous and completely uninformed claims, as have numerous people. There's no real point in overclocking. . . really. . .

 

dont listen to nissangtr there is plenty of room for oc, and it can be overvolted aswell, as long as proper cooling is available.

 

I said basically the 670m is virtually on the limit so if you oc there is not much to find and most likely if its a 180w psu it won't handle it and definately not on 120w.

 

I have no clue why the mods let nissangtrwhatevernumbers run around here unchecked while spitting derogatory nonsense everywhere. No. Freaking. Clue.

Last I checked we were in the Gaming sub-forum, not the Performance Per Watt or Technological Achievements sub-forums.

 

Or the I-am-always-right forum. I thought forum rules specified that there needed to be sources for everything? Where are sources for his 180W psu numbers? chuckles, get the 675m if you can.

 

You can increase voltage using sVET's Fermi vBIOS tuner

Svet's Fermi VBIOS Tuner - [ver: 1.28s]

 

dont listen to nissangtr786... pretty sure he is the village idiot of these forums. the 670 has huge OC capability provided you have adequate cooling

 

I wouldn't OV the card so soon. You don't want to mess something up plus OP sounds like he is new to this stuff. Even I'm not confident doing this and I've been in this for quite a while. That being said, me not being confident doesn't mean someone else cannot...so...yeah.

 

Or instead of paying for a rather stupid flashing app I can do it for you by hand.


Let me take a look at your vbios and I can tell you whether there is an additional voltage setting available.

 

It has one of the lowest oc capability of the 600m series.

 

Ya lol, I have an MSi GT60 0nc, bought the 670m thinking it would be kepler (I was a n00b then) and I get a ridiculously power hungry kepler card. (I decided a laptop was a bad idea, so im getting a 660 Ti over the winter)

Either way, as far as overclocking goes, the card should be stable at 900mV with a clock of 750MHz on the core, that would bring it close the GTX 560 levels. I got stable 755MHz core and 1700MHz memory, ran furmark pretty well. The card should OC pretty well into the 800-900MHz providing your cooling is good, the power supply is good and you can increase the voltages.

On that run at 755MHz I started at 30C and ended at 69C after 35ish seconds, I had ice packs under the laptop and was running in a cold room. I might fiddle with the cooler and add a dissipator and fan on top of the current heatsink to improve cooling.

That nissangtr guy is full of , the OC capabilities of Fermi are quite impressive, considering that the core clock is by default significantly lower than Kepler, 755MHz is a 21.7% OC on the standard 620MHz clock, quite impressive considering I can't (yet) change the voltage.

@svl7 Could you do a vbios mod for me PLEAAAAASE!!! Svet is a rip off with the donation ware, if I myself modded the 670m bios I'd give it out so svet doesn't get the muneeh

 

I'm not disagreeing nor agreeing with you because I don't know how does it fare in OC % when compared to other 600M series. Not gonna suggest you to turn your 670M into a smoking hot sexy piece of card with visible smoke coming out but you might want to OV it slightly if you are seeing some bad OC % on your 670M.

 

I did overclock it to 720mhz Core Clock and 1600mhz Memory Clock. How much more relatively safe overclocking would be advisable?

 

..the temps. of the GPU and CPU will be your guide, plus once OC'ed there shouldn't be any artifacts showing or any anomaly while playing demanding games on your OC'ed GPU.

I'll say 80*C for the CPU max and for a Kepler 670M I'll say limit yourself to 79- 80*C max GPU temp. (for now).. HWinfo 64 can monitor both CPU and GPU while it's minimized , and while you're playing demanding games.

 

I wouldn't worry about going over 80C, especially since it's a fermi card. I would try to keep max temps in the mid/high 80s and below.

 

On stock and the slight OC, the GPU temp was at 69-71*C while heavy gaming ( BF3, Sleeping Dogs, Hitman Absolution etc )...So what clocks should I try next? I ask, because i didn't OC anything before.

 

Wow, those temps are really low. Nevermind, maybe you shouldn't go over 80 then. At least to start with. Hopefully someone can chime in here with recomended clocks for your card, but every gpu is different. Start conservative, pay close attention to temperatures, and watch for stability problems like crashing or artifacts. It's a good idea to use a stress test like Kombuster to make sure the oc is stable.

 

I avoid going over 70, but usually during heavy daytime gaming sessions the temps get up to high 75-79. (620MHz) During night OC sessions I let it go up to 85C, usually it stays within that at 700-720 MHz (dependent on air temps), I expect at 900mV you might be able to get close to 800MHz, but unless you fiddle with the cooling those clocks are unrealistic. The memory seems to stay stable up around 1700-1740MHz. If you need the OC I'd suggest you test with furmark, go 10 MHz over what you get 90C with while running furmark. Otherwise you are just eating away at the life of the power supply and mobo of your laptop.

EDIT:
HARD NUMBERS (tested with Furmark):
at 900mV max stable core clock: 780MHz (@790 i start getting artifacts)(Memory clocked at 1700MHz)
at standard settings with 680MHz core clock, max. stable memory clock: 1740MHz (1745MHz and above gives artifacts)

(These values tend to be chip specific, they might also vary between different stress tests, Furmark stresses the memory controller to ~70%, other programs might need more, others less)
