Framerate affected after long use?

I have 14 posts and 4 thanks, do I need 5 thanks?

 

Mr.Fox, Svl, Thanks a lot!

unlocked the potential of the card, check this out


Temperatures are wonderful, room temperatures is 24 - 26 °C, the laptop rest over a coolermaster U2 with 3 fans taken from my U3 . I'm at 1.1V, 1175Mhz Gpu/ 1377Mhz Ram. No artifacts or instability/throttling signs. Yesterday after several benchmarks, plus some hour of gaming, i let it running the whole night with Heaven 4.0, and found it in the morning still up and running with gpu temperature stable at 58 °C
The card can go higher and i will try to find out the ceiling for 1.1V, i'm not willing to go any higher with voltage.

Edit, under load during 3Dmark11 run, the output from my UPS reads 117Watts.

As i stated in another thread, the 14 could have handled a 770m without problems, both under power requirement and thermal point of view.

 

You are getting fairly close to striking distance from 6990M CrossFire performance with your baby beast. That's pretty impressive. Why no link to your 3DMark score? I can't see your CPU/GPU scores with GPU-Z covering them up.

Here is a link to an old benchmark of mine: AMD Radeon HD 6970M / 6990M video card benchmark result - Intel Core i7-2720QM Processor,Alienware M18xR1 - P6377 3DMarks

 

I've saved the result, here is the link NVIDIA GeForce GTX 765M video card benchmark result - Intel Core i7-4700MQ,Alienware 07MJ2Y

 

Your lucky at 1.1v I couldn't even get 1100 mhz out of the GPU using Nvidia Inspector. It would start throttling in BF 4, going to 405 mhz up to 700 800 etc.
Funny thing is, no Display crashes...so i dont think it's my clock, I actually think it's the game maybe?

I didn't do anything other than Nvidia inspector, should I be doing something else as well?

Edit My GPUZ info, @ 1.075V I haven't tried budging the memory any more. I think memory clock has a pretty big impact in BF4...I've seen 3-5 fps higher for a 15% boost almost...

This seems to be 100% stable in BF4. I'll try +112.5mv or something next time I think our max is 175mv

 

With results like that you have me convinced to flash the vbios and unleash the OC potential.

EDIT: Can't seem to find a link to the vbios, where did you find it?

 

If it can help, I'm using EVGA precision to clock the card. Out of curiosity, what's your ASIC %? My chip is close to 68%

Edit: vram Oc will lead you to better improvement over Gpu frequency since the 765m with a 128 bit memory bus is starving for bandwidth.

 

I found what I think is the correct modded BIOS but need to make 5 posts over techinferno to be able to download attachments.

I plan to do a fresh install of W8 soon and will flash the vbios after that. I'll post up before and after screenshots of some benchmarks with the +135/+400 settings that I run now and whatever I can reach with the new vbios. We'll see how it goes.

 

About the same as yours, 67.9% lol, have you tried bf4 per chance? Playing other games seems to be stable for the higher clock, but BF 4 eventually starts throttling!

 

How much of your system RAM is being gobbled up by BF4? If it is using your pagefile (swapfile) it might be degrading performance to some extent. I have seen at least one person that identified 7GB of system RAM utilization and almost 2GB of vRAM usage in BF4 and he is upgrading from 8GB to 16GB to see if it helps. http://forum.notebookreview.com/alienware-18-m18x/737537-advice-hyperx-2133-ram.html

Even people with very powerful CPUs and dual graphics cards are seeing some performance glitches with this game. It is probably, at least in part, sloppy game programming. As it is a new title, some of that may get better with game patches and driver updates.

 

Wow! Very nice clock, I can't reach NEAR this at all without artifacts.

 

Probably a stupid question here. When flashing a custom vbios from Svl, does it matter what OS and bios I'm currently on? I'm used to OCing, but not flashing.

How high can I turn up the voltage on the GTX765M?

 

Page file is very small, I set it to 500-1500:S Maybe that is the problem:S But it runs at 1200 mhz for a while, then it suddenly goes down. Once I start playing over games it also does the same thing after playing BF4. Maybe BF4 is crashing my drivers?:S

 

Now my GPU seems to be downclocking itself drastically everytime I set a OC. I am using maximum performance so it isn't that, but i'll clock over half under DEFAULT clocks. Help here fellas?

 

I think it's the drivers, they crash when it starts to down clock itself or the OC isn't stable. When I oc to 1050mhz it is rock solid. Anything over it, depending on the game it will start fluctuating. For example I can play cs go for hours @ 1250 mhz yet it crashes in bf4 after mins or seconds and it starts to fluctuate up and down.

Try increasing voltage, but remember the higher the voltage the higher the risk of burn.

 

I put the voltage up to 1.1 but it still doesn't change the underclocking.

 

Yeah 1.1 did the same for me:S I try my oc and see if it's stable. Check out my GPUz from before and set the voltage to 1.075v

What I've noticed with OCing video cards is that they each have their sweet spot, or a frequency/voltage it prefers to stay on. Yours might sadly be a case where ocing might not work passed a certain point, mine looks like stability stops at 1050 but I haven't tried enough. I'll try to increase voltage to 1.125v and 1200 with bf4.

I took me putting voltage of 1.15 to stabilize 1152 mhz 300+ mhz (memory I'm going to try boosting to 500 mhz if not I'm happy with oc) I tried 650mhz memory then it started throttling and artifacting. Again this is BF4, in other games it seems to run fine, but once it screws up in bf4 it screws up for all games.

Edit

The most stable I could do it so far +250 mhz core and +300 mhz memory ( I think i can budge up the core to 275 stable but I'm happy with 250 for now and the memory to at least 400-450 )

Try the voltages I gave for 1050 mhz core and 300+ memory @ 1.075v See if that works

Edit2 played an hour of Splinter cell with my second found clocks and its Rock stable. @ 250mzh and 300mhz +, frame rates over 60 with the game maxed @ 768p (dips to 40s in rare occasions if there are a lot of effects on screen!)

BF4 is now 60+ with everything maxed and mesh on low.

 

Im playing COD: Ghosts at 1100/2300 with a voltage of 1.1V .... can play for a good 30 min after which either there is a driver crash or there is a drop in both clocks .. any idea how i can get rid of this ?? I have modded the VBIOS using svl7's mod. Temps hit 72C and the VRAM usage goes to ~1960MB

Are u doing anything else to get such high benchmarks without experiencing any throttling ????

 

Not really.. Try using k-boost in EVGA, to force clocks & voltage, use it along with a custom hwinfo fan profile you can lower the tempo by a good 5 degrees

 

I tried using k-boost as well .. no hope ... can u please show me ur fan control look-up table setup in HWINFO ??

 

I'm pretty sure this is due to your driver failed because of the clock instability. My only suggestion is, try increasing your voltage and see if that stabilizes it. Just watch the TEMPS!

I know this from my lenovo, any time the drivers crashed the clocks would not longer stay clock up, it was start dropping to 405 mhz consistently. I think ours does this because we flashed the video card bios while mine was a system bios.

I'm about 90% sure its your clocks not being stable. For example my clocks passed unigine test with the lower voltage and played cs go, but failed in BF4. Depending on the graphical demand your card will be crashed if not stable!

 

You're right ... i dont face the same issue in arkham origins .. I was trying out your OC (+250 core/+300 mem with 1.15V) ... It was fully stable with arkham origins but once i play COD:Ghosts core keeps dropping to 768 occasionally

It's the game perhaps ?? I used to have a M14xR2 and man overclocking the GT650M was like magic ... used to work perfectly with 1100/2800 at 1.037V ... games were super smooth ... Im regretting giving it away now ...will there ever be a fix for this ?? Getting sick of this throttling with the OC

 

There might be a fix or a hack directly through the bios. Don't regret selling it, this card has nearly double the power on paper and can oc pretty damn well!. I have it at 1150 mhz stable right now with +300 so you just have to find your groove!

 

I'm starting to get PWR throttling with both the modded bios and the stock bios, which is what is making me underclock. I can't figure out what it could be all my power settings are correct...

 

What I would do is see if you can find a watt measurer, your power supply might not be working properly. The laptop throttles but it shouldn't be doing it so easily.

I played BF 4 for 2 hours without any throttle and the GPU temps were 72. Also try using Nvidia inspector to increase the acceptable heat capacity, and switch off heat prioritizing.

 

I also think there is a possibility the AC adapter might be wimping out. It takes a little while before it starts to happen. While not conclusive, that may be an indication of the AC adapter breaking down under load.

 

Like I said, your clocks and voltages work amazingly well on arkham origins for me(Im playing with ultra settings except for the AA which is at 2xTXAA) and the game runs so smooth .. i do see a drop probably once in 30 min but thats just for a short while (~1ms) .. so while playing there is no problem .. its only when i look at the GPU clock graph that i know that there was a drop ... but this is fine as 99% of the time the game runs perfect.

But for COD ghosts, only in certain levels (such as the underwater level) i see massive fluctuation of the core .... the final levels and levels inside buildings are no problem at all ... the temps for this game go upto 74C ... I know im being very game specific here to explain my problems but these are the only 2 games Im playing right now ...

Do u still see occasional drops/fluctuations with this OC in BF4 ? Anything else you are doing (cooling pad , Fan Control etc...) ?

 

can u please show me ur fan control look-up table setup in HWINFO ??

 

I am indeed using a cooling pad! I didn't mention it because it doesn't really make that much of a difference from my experience. It prob shaves of 1 degree at best most of the time. This laptop has absolutely astounding cooling, I think adding another fan blowing on it will only hamper it down. I think the cooling pad should be without a fan and will prob help getting the heat away from the underside.

I would double check your PSU (aka the power adapter) to see if it's working properly. That is very easily replaced!

 

what do u mean by this ?? and how do i check if its working fine ?

 

My 14 crashes with simple +50 on core and +75 on ram with precision x. I'm guessing I need to bump voltage up a little. I might flash mine today and try it. I have my 18 AC adapter I can try also to help determine if it's psu issue.

 

please let us know how it works out for you

 

Try to get a multimeter and mearsure your output, and try wiggling the cable or seeing if the power drops consistently and drastically, this most likely means your PSU is malfunctioning (try jiggling the power cord a bit too to see if it's movement or the power bar).

If that works out fine, then most likely your video card isn't capable of OC, or if it can't even sustain stock, then it's most likely malfunctioning.

Mine starts throttling at 71+ Degrees, and it's only for half a second, then it goes back to full because the fan kicks in.

Well, my CPU doesn't loose voltage when throttling. My power brick doesn't get hot at all and my PC never breaks past 55c. I tried jiggling the PSU cord around and no changes.

 

The CPU most likely has a lower tdp than the GPU, and especially if your overclocking and over volting, your tdp on your card can grow pretty fast. There many factors at play, and I think CPU takes precedence over video card in system, though don't quote me. There could be power loss on the card itself. I notice your card starts lower voltages in the picture.

I thinkt he primary question is, does your card work fine at stock? If it does, then your OC is mostly not stable and might not be possible period.

Try Slv7's stock, then roll back to dell stock. If it still throttles aggressively it's definitely something wrong with the laptop. Mine use to throttle but putting it in discrete mode solved it.

 

Funny thing is, this didn't happen until 3 or so days ago, before that I was able to successfully OC with no issues whatsoever.

 

I have no issues with stock clocks .. they work absolutely fine ... no throttling .. however i might have found a stable OC .. will post back after more testing.

I have also under volted my CPU core ... i guess this coiuld be the reason why i have a stable OC .. anyways will test further and post

 

Appreciated Give us the break down when you can, I'd love to undervolt the cpu as well, but frankly I'd rather not touch it's voltages if I don't need to

 

If that was true with either vBIOS, then something changed. This is what causes me to have at least a question mark about the AC adapter not being able to keep up after it has been under load for a while. It could be a weak unit.

 

Here's some benchmark results before and after vbios flash:

Completely stock:
3DMark11 4223

+135 core and +300 mem (old highest score): 11% increase over stock
3DMark11 4698

+200 core, +200 mem: 15% increase over stock
3DMark11 4855

+250 core, +300 mem: 17% increase over stock
3DMark11 4966

I can't seem to OC any higher. Even a +25MHz boost to core or mem causes instant throttling on 3DMark11. I was hoping for higher OCs, but I guess I lost the silicon lottery with this one. Either way, 1150 MHz core and 5200 MHz memory isn't too bad for a mobile card in a 14" laptop. I rarely exceed 70C with these settings, so the cooling system far exceeds the GPU's capabilities. I don't see why a GTX770M couldn't have worked in this machine honestly.

77% ASIC for what it's worth.

EDIT: Huge shout out to Svl for his modified vbios.

EDIT #2: After running a completely stock run (the way it ships out of the box), I'm more impressed with the OC results. A 17% boost is graphic performance is pretty impressive for a very small increase in temps and noise. It's certainly nothing to scoff at it like I did initially.

 

Hmm, I was thinking that my 14 (2013) was throttling, but now I'm realizing it's instability. I'm only running at 1035 MHz and temps remain below 70 (dedicated mode), but randomly the GPU & Mem drop to 405 and then stay there (playing Sleeping Dogs).

Sometimes I can go back to the main menu and the clocks go back up, but once the game starts again they drop back down to 405 MHz.

I have to reboot to get it to work properly again. Today after it happened, the screen flashed and a warning came up that the driver crashed and had to recover. At that point the clocks went back to normal. This is with the Dell drivers from last month. I'm going to try the new drivers that were released yesterday and see if they make a difference.

 

Yup, just look for your sweet spot
