GTX 980M Overclocking

Actually, my bad, was misremembering. OC'd at stock voltage, I was getting high 70s in Fire Strike, not low 80s, so it's a little better. But yeah, I saw it hit and then cross 85 on Fire Strike when OV'd. I'm going to keep looking for a sweet spot for optimal performance though.

Incidentally, is AC3 just absolutely awfully optimized for PC? I've got it at max settings, plus added AA/AF/other stuff I can't recall via Nvidia Inspector. It looks quite good, but my FPS is about 40 OC'd, with VSync at 60 Hz, and my temperatures actually hit 85 yesterday for the first time while gaming.

 

youre a bit late to the party it seems AC3 indeed seems to be one of the most awfully "optimized" games for the PC. so if u can actually run it fluidly on max settings ull be in a very exclusive club. if u cant, dont worry, 99% of users cant

Late is right. I tried playing it with a GT 540M years ago, but God the game was awful. And still is. It's not yet uninstalled simply because I have the drive space to not care lol.

Well, I guess I just shouldn't worry about how it plays then. To the overclock-mobile!

 

I try ov and oc at 1.187v for 1500/1490.
It start running the 3dmark11 firestrike.
I didn't though it will run...
it start nice and after 45 sec my laptop shut down....
to be honest I scared!!!!
I tried to activate my clevo....nothing!!!
I pull off the ac adapter and plug in.
then the lights shown up again...fsssssss....relief ....
I will never tough the volts again!!!that's for sure!!!!

 

lol, good start into the overvolting game it seems id go at it step by step actually, not brute force style... up the core clock until it gets unstable, then up the voltage one increment (for the 980M its 12.5mV, dunno about the 970M), then up the clocks until its gets unstable again....rinse and repeat!
at some point ull reach clocks that u cannot get stable, no matter what voltage u apply. i hit that wall around +290 Mhz, at +300 Mhz and above i need to feed exponentially increasing voltages to get it stable, so not worth it anymore...

I think that it can hold that clocks with 1.187v but I think also that im limited with the 330w ac adapter...lol

 

hmm wait, ure sporting sli right? that could indeed be the case then! im already able to break 300+ watts on my oc/ov machine, so 970M sli oc/ov could easily break 330W.... how about a y-adapter together with a second 330W psu?

I think your right...
where I can buy one?

 

I advise everyone with a 180W adapter to get a power monitor thingy. That way you can easily see when power draw gets to danger levels and quickly stop the benchmark before your PSU goes kaput.

I'm still yet to finalise my stable clocks when overvolting. VRAM limit is around +110 in Unigine benchmarks. Stock 1.0500 voltage imposes a +125 limit on stability during Unigine benchmark runs.

I know heavy overvolting quickly sends power draw over 180W, so I gotta be careful. There's a delicate balance to be found here.

 

Why don't you just buy a 240W brick

 

also check the efficiency rating of your psu that way u can realistically calculate the max. power draw at the wall ure allowed to get mine at 87% would be 330W/87%=379W at the wall

ebay, btw! clevo extreme gaming offer such, for example. or eurocom

Mine says Efficiency Level V on the back, so that means >=87% efficiency at 50-250W?

yep, thats correct mine is the same

Like this one? http://www.amazon.co.uk/DELL-PA-9E-Adapter-19-5V-12-3A/dp/B003QQJ5BK

How many people have successfully used one of these with a P65xSx? I'm cautious. It's a lot of money to spend on something that has the potential to brick the laptop if I screw it up.

 

Why would it brick the laptop? Anyway, HTWingNut's been using one on his P650SE. I just got mine, now waiting on the adapter to arrive so I can use it on my P650SG.

 

My 3940XM which is OCed to 4.2GHz on 4 cores + 970M Oced to +430/520 causes PSU to trip in FS GPU Test 2... Your 330W PSU also probably tripped there... You have 2 970Ms and a 4800MQ which sucks power like nothing so time to get a 2nd PSU + converter box

 

you heard the man, UPGRADE YOUR PSUs, NO EXCUSES!

 

Close enough. My 880s had a slight edge in this run but stock 880Ms definitely get smashed.

lol thats crazy, already managed a 12% higher fs score than those 880Ms in SLI

980M is a beast, or rather the card that the 880M was supposed to be

Sent from my Nexus 5 using Tapatalk

 

The graphics score is what is accurate, my CPU throttled bad for the combined test which is what screwed the whole run. Graphics score slightly favors the 880M SLI but those are "fixed" with svl's vbios and Prema's system BIOS for PCIe 2.0, the results at stock stock are an entirely different beast.

whoa wait, 980m is better than 880m in sli!?!?!?

 

Yeah, because 880M is a POS remember?

 

well time to get a new job and upgrade. hitting 93c playing bf4 right now with vsync on lol

 

When the 980M has a decent overclock, yes. 880M overclocks too, good luck keeping it cool though.

http://www.3dmark.com/compare/fs/4399791/fs/2326858

14k graphics score... Temp was 93C at the end of the test so I didn't push the cards further

 

Bloody hell.

My latest score: http://www.3dmark.com/fs/4419330

OV of 37.5 mV to 1.1 V
OC of 230/150 to 1268-1356 boost/1403 MHz
Inspector temperature target adjusted to start throttling at 85 C (which I hit during every run)

I'm not going further, I promise!

 

Time for Liquid Ultra lol

 

Hmmm. I've got XoticPC's IC Diamond upgrade. Is Liquid Ultra better?

 

It is but its risky if you don't apply it carefully as it is liquid metal and also eats aluminum so you have to be careful with it. I personally won't use it again because removing it I had a near fatal disaster when a bead fell off the qtip. If I didn't have an SLI cable to catch it, I may have fried my whole machine. It definitely keeps things cooler though and it doesn't reach its peak temperatures as fast which lets you run higher clocks for a shorter time. More trouble than its worth to me though.

 

@Ethrem Yeah, I've never done paste applications except on a toothbrush or for arts & crafts in elementary school... I think I'll put it off till I have to repaste, if I ever have to lol.

Btw, I know this is unrelated, but could anyone here help me out? I had 2 8gb sticks of RAM (CL11, 1600 MHz). I earlier today cannibalized my old laptop for its 2 4gb sticks (CL9, 1333 MHz), ensuring that all 4 sticks operate at the same voltage (1.5 V). I was under the impression that the entire set would operate at the slower speed, ie CL11 and 1333 MHz. However, my mobo is actually running them at CL9 and 1333 MHz, no issues so far. Any thoughts as to whether this is sustainable?

 

Repasting itself is not that hard. I've been building computers since I was a kid and this machine was my first time repasting... I've now done it ... well lets just say enough lol.

Most 1600MHz RAM will do 1333MHz CL9 pretty easily but you can always grab memtest and leave it running overnight if you're worried about it.

 

And just imagine how the guy from youtube that he has the p650 with 970m he ov-oc at 1.2+v with clocks 1580-1500.
What ac adapter he has for this laptop?
I think the stock ac is 180w right?

 

Hi. My 980M's Core Voltage remains unchangeable even after I unlocked it in Afterburner. Is it normal that I cannot set it or is something wrong with it?

 

I'm pretty sure you just have a locked vBIOS and you'll need to flash an unlocked vBIOS to be able to change the voltage. Before doing that, try NVIDIA Inspector and see if that lets you change your voltage.

 

Afterburner doesn't allow voltage changes.. Use NVIDIA Inspector..

This. Also wanted to add, avoid Precision X at all costs or you might be putting your LCD at risk!

 

Bizarre bug isn't it? I use Asus OC tool, but used Afterburner and Inspector, all work great. Then to read that EVGA has to do something bizarre destroying LCDs... why?

 

Messing with a single 980M, +270/+500:

lookin good there @ssj92, im getting basically the same scores with +250/+450 on gpu, 4.7ghz cpu and ddr3-2400

so that 10% more for you on the gpu and 9% higher clocks on my cpu

Hey guys I ran into a problem. I was trying different programs to overclock (Afterburner, PrecisionX, and Inspector) and I think Inspector messed up my settings now I cannot reset it. I tried resetting in all 3 programs but the GPU clock keeps staying at 1126 (default = 1038) and memory clock at 2505 (default = 1253). How can I reset it back to default? Please help!!

UPDATE: OK I think I solved the problem (well more like a workaround really). It's a conflict between Inspector & PrecisionX. I believe when I started messing with Inspector I didn't reset PrecisionX completely. I did reset it to default values BUT I didn't turn off KBoost and the result is that when I clicked APPLY in Inspector, somehow it added the previous settings from PrecisionX. So now my DEFAULT is set at GPU Clock 1126 and Memory Clock 2505. And no matter how I reset the values in different programs, that's now the new default.

And here's the solution/workaround, turn KBoost back on in PrecisionX. Even though the default is still the new values (1126 & 2505), but at least I am now able to change the values in Inspector and take effect. I can lower both GPU Clock and Memory Clock back down to the true default values and it sticks now when I click apply.

If anyone knows how to reset my current default back to the original default, I would still like to know though. Thanks!!

 

theres no problem in your case, since those ARE your default values

the 980M sports a base clock of 1038 mhz with boost to 1126 mhz at stock

as for vram, 2505 ddr mhz IS 1253 mhz real clock. check for yourself: 2505/2=1252.5

so your all good, both values show stock

Ooh I see. So basically Inspector reads the DDR # and the other programs don't?

Whew I was worried I messed up the card ............ Thanks a lot for explaining. =)

How come in Heaven Benchmark, the GPU clock jumps between default 1038 and boost 1126? I was worried it's reading 2 defaults.

 

yes, depending on which tool u use to read the vram clock, itll either give u 1253 mhz, 2505 mhz or even 5010 mhz

im guessing youre sporting the stock vbios, as those fluctuations between base and boost seem to be "normal". i can personally only rely on reports and hearsay in this case, as ive used the premamod vbios ever since i switched on my laptop the first time, basically so no fluctuations or power throttling here, stay rocksolid at 1126 mhz

What do you get @ 4.7Ghz? Here's mine

 

haha, showoff!

my physics score at 4.7 Ghz matches yours at around 4.3 Ghz in the 13.5-14k range. the difference is accounted for by the increase in IPC and faster RAM id say

 

That's not bad considering Skylake is two generations newer than Haswell. I need to delid this thing so I can go for 4.8Ghz lol.

My second 980M is a huge bottleneck. My first one can do +300/+400 but the second one won't go over +180/+400 at all no matter what voltage I use. I will have to try and see if I can get it cold to 50C and see if that helps.

 

oh im definitely not complaining! my cpu maxes out at 4.8 ghz, 4.9 onwards will probably be impossible to get stable unless im applying insane voltage and ambient temps below freezing *lol* itll be a while until any intel cpu will reach that performance at stock, let alone significantly trump it so ill be good for several years

gpu-wise id say im somewhere midrange, not excellent but not bad either. i can do 250/450 rockstable and 290/500 for single benchmark runs, anything above that just draws too much power and my system blacks out (not psu-wise, rather VRMs on the gpu most likely).

 

if i run mine at 1.3ghz it will freeze then shutdown....though at the time i had RAM with different timings so that might have been a cause but can't be sure,

 

OK I think I really did mess *something* up with PrecisionX & Inspector. When I first used Afterburner, I was getting average 55 FPS & 107 Max FPS in Heaven Benchmark. But after using PrecisionX & Inspector - now no matter what I change (even in Afterburner) or resetting to default clock, I am getting 45 FPS & 70 Max FPS. I am guessing that's the stock rate for my laptop. So it's like no OC applies anymore. Can anyone think of what I touched that caused this change? O__O

 

try the following: uninstall both inspector and precision x, use DDU to uninstall gpu drivers, reinstall drivers, then try again with oc

Nope. That didn't seem to work.

I think there is another problem to my situation. Which is that my card is now capped @ 60 FPS. Even though in my last benchmark the max showed 70 but I think that's just a sudden spike. I noticed my FPS never goes beyond 60 during benchmark. Then I just tried to lower the settings from ultra to low & even lowered the screen resolution, and truly it still never goes above 60. So it seems like somehow the card is now capped. I wonder if it's caused by overclocking or maybe it's something else entirely that caused this.

I already disabled V Sync in Nvidia Control Panel but that didn't help. Any more ideas?
