980M OC thread!

Please post your results of OCing your 980m with system specs. Lets find out a good range of OCs so everyone knows what to expect!!!

currently no way to Flash BIOS yet so max OC is 13%. See Post 5 <--click or scroll down

 

+1 to this thread I'm very keen also to see the results. I'm thinking of a 980M which will be as good as my R290 Tri X once OC'ed I hope

My Tri X runs every game i throw at it in 1200P

 

First we need to wait for unlocked vbios, otherwise we will have a standard run of +135mhz core and perhaps +500mhz memory for some. Like we did for 780m haha

 

ok so thats a start in information..what % boost is that?

 

Getting an unlocked vbios isn't the issue. It's flashing it. nVflash won't work with 9 series cards at the moment.

Here's difference between stock and +135 OC with +500vRAM (6000MHz effective).

That would be +13% Core, 20% vRAM. Results to be published soon.

 

gaming difference? like whats the new firestorm score? %+

 

We already know the 980M has 64 ROPs and 96 TMUs not the 32/128 as GPU-Z is claiming there. The pixel/texture fillrates are therefore incorrect. The rest of the specs look correct though.

It'll be interesting to see how high it can go! The desktop 970's can get to 1500MHz on the core. Does a notebook cooling solution exist that can handle that power? Time will tell... (let's hope so!)

 

Here's Fire Strike stock and OC:
Stock: http://www.3dmark.com/3dm/4324125
Score: 8118 / Graphics: 9446

OC: http://www.3dmark.com/3dm/4407776
Score: 9010 / Graphics: 10663

Same about 13%

It is correct, it's coming off the GT72 sitting in front of me, lol. Considering stock config runs at about 70C with fans barely running in this GT72, I'd say most full size laptops will have no issue cooling with significant overclock.

 

I'm not saying you're wrong, I'm saying the software has got it wrong. 980M has 64 ROPs and 96 TMUs - this is 100% confirmed. GPU-Z has not been updated to recognise that yet. Here's GPU-Z screenshots of desktop 980/970 to illustrate what I mean:

Spoiler

 

I'd be more concerned about the power circuitry than core cooling if you intend to push 1500+ core tbh

 

Power circuitry of what? The laptop or the power supply? So far even with the slight overclock it's not pushing much past 180W draw from the wall. It might require a bit of an overvolt but still will remain well under 230W to achieve 1500+ core.

 

Power circuitry of the GPU itself.

 

i doubt the 980m has the same quality parts as a high-end desktop card meant to be OC

 

Holy thats amazing.. Maxwell is truly a god send.. Thinking Gigabyte laptop might not be an urban legend, wish they had better build quality (looks like its the same chassis from previous gen and last reviews were horrible)

 

The chassis has been updated. Gigabyte rep confirmed this to me.

Look at it this way, back then the ov 680m easily overcook 50% and it was more of a thermal ceiling. 1500 is not that unrealistic.

 

Fingers crossed for that mate, and will be waiting your news as soon as you have your machine

 

Keep in mind that desktops are able to achieve 1500+ MHz due to >200% power headroom and extremely high, potentially unsafe (in the long run) voltages in the 1.25-1.3V range, which I have not seen on Nvidia since the 90/80nm GPU's 7-8 years ago. Kepler was already creeping up there toward the end of its life cycle, but Maxwell takes it to a different level. Sure, pumping all those volts into the GPU gets you some impressively high clocks while staying on 28nm, but the price to pay could be dead cards a few years down the road.

 

And hence my comment I'd be more concerned about the power circuitry than core temp at 1500+ core on the 980M. But there's also the core getting fried by volts part as well.

Oh and just to throw out a data point I was able to squeeze out 1524MHz core on my desktop 970 without touching voltage. Master ran at 1.212V while slave was 1.200V. Although I only ran Heaven for 2 minutes so no idea how stable it is. I can say however that 1504 MHz core is at least 30 minutes stable in Heaven (only tested for 30 minutes). Based on what I've seen my results are quite run of the mill. One golden MSI 970 was able to hit 1600+ core without touching voltage.

 

Hey HT, how did you OC it by 13% without the flashed vbios. Is it a rather simpler OC compared to a vbios OC. Im a beginner and I would love to be able to get 13% with a simple OC. Thanks!

 

nVidiaInspector... Click the overclock button and move the slider and apply... done. Glitch with nVidiaInspector may have to set the overclock again since it likes to reset the first time.

 

Thanks a lot!

 

Nice job as always HT.
How you liking the GT72?
In your opinion is the TN screen good?
Nice to see these Maxwell GPU's OC so well.

 

TN screen is good, not great. I'd say it's above average, but not great. Vertical viewing angles could be a bit better, but at least they're not tunnel vision (like +/- 40 deg like some I've seen), it's +/- 60 degrees I believe.

 

is it like the alienware TN if so impersonally would have no complaints

updated first page with current info. Let me know if it changes

 

nNVFlash works for desktop Maxwell cards

Not sure if it'll brick mobile cards so obviously try at your own risk

 

Already tried a week ago... Did not work..

 

Should be a new version judging by the upload date, so probably worth a shot.

 

Nope already used 5.190.

 

Step by step guide using KBT to mod the BIOS and then flashing your own modded BIOS.

If this doesn't work then probably limited to desktop cards atm.

 

hi, i just got my 980m laptop, my max current temp is already 85 C, so i plan to apply some real good thermal paste, so i won't able to OC anytime soon. However, out of curiosity, how much increasing temp u guys experience if OC +135mhz core and perhaps +500mhz ? And around how much fps increase in real life gaming given that amount of OC (maybe any game examples ) ? Thanks

 

Put a small item under the back middle of the laptop for increased elevation - it'll improve the airflow and drop you down by 3 C or so.

I can overlock by 135 and 300 respectively and don't go above 83 C mostly. Was just going by percentages so didn't think to try 500Mhz.

Problem is, I do get a black screen on DA:I if I do this for too long. However, DA;I has been funny with my HDMI out anyway, so I can't tell if it's an OC issue or just a dodgy HDMI cable. I'll have to switch it out and check. Or just play on the laptop screen itself.

 

Thanks, one question : so if u OC, then the temp will max at 83 , then if u dont OC, what is the max temp ? so i will know how much i will expect my temp will increase if I OC and everything goes ok

 

U're a genius sir, after I put a cushion under the back middle of the laptop for increased elevation for like 3 cm, the temp reduce 4 C !!! genius sir

 

That's why laptop coolers are essential.

Just got my G751 and have been able to get a stable +135 on the core and +450 on the memory I think 500 is possible I've just not had time to play with it yet. I'm just blown away with the 980M, coming from the 880M its not just better, it's in another league. What impresses me the most are the temps. Yes the G751 has allot to do with that rather than Maxwell. With the OC I'm seeing 69c and when I've got it on my lap covering the air intakes and maxing out COD:AW its around 73c crazy low.In comparison my old AW17 with the 880M was hitting 92 on a flat table with the clocks throttling.





NVIDIA GeForce GTX 980M video card benchmark result - Intel Core i7-4710HQ,ASUSTeK COMPUTER INC. G751JY





As you can see temps during the 3D mark 11 run never got over 69c.

The most impressive thing for me is how it feels in games. I've come from on old SLI 400 based desktop, I must have gotten used to the stuttering, as 40fps looks so smooth on this new system and when you look back at the desktop it looks unplayable. I've been able to max out Watchdogs HBAO+ Ultra Textures etc fps is around 60-70 dipping to mid 40's sometimes but that's mainly because Watchdogs is broken. COD:AW everything maxed and with 2x Supersampling I get around 90- 120fps never really dipping below 80. Super impressive considering my old 480's locked up at low to medium settings.

If anyone is interested I can fire up my old desktop that the G751 replaced and do some comparison benchmarks. It's got a 480SLI 2600K. If I remember correctly it can score around 41 fps in Unigine heaven 4.0

 

Not surprised with your experience.. The 880M is a overheating turd and so called Alienware's epic cooling system is noisy and compared to Asus's... However, I wouldn't play those games on my laps even with 70C temps...

 

I did find the Alienware cooling infuriating. It did it's job well but just wouldn't spool up all the way even at 92c on the GPU! For me 70c is more than cool enough I've owned my 2 480's in my desktop since 2009 now and they've run at 92-98c 24/7 for all that time with no issues. Granted allot of that is down to the GF100 but for me anything below 80 is fine for daily use when you get into the low 80's it's a concern and anything near 90 is dangerous for daily use.

 

Impressive score, good job. I'll see where I can get in a couple of days. I want to repaste first.
Thanks for the tests.
