Recommended overclock for 780M? (AW M17x R3) 240w PSU.

Hey everyone,

What is the recommended overclock for the 780m? I've used MSI Afterburner and Nvidia Inspector and overclocked but when gaming it either crashes the game or causes visual glitches.

Should I decrease the clock? Increase power/temp target? Increase voltage?

If so by how much. Thanks guys .

 

please look up and read about how to overclock there are plenty of really good guides out there.

each card is different & will take different clocks & voltages

if you are having artefacts/crashing then either you have two high of a clock or not enough voltage


keep an eye on your temps & good luck

Also, I would advise staying away from afterburner & EVGA person x on win 10 with an MXM Alienware laptop

 

I 2nd this. Stay 100% away from PrecisionX or you lose the screen.

 

What's your settings?

 

Agreed 100%.. Another Victim of NVIDIA Fail + Micro$haft!!

 

What can cause it to kill my screen/card/laptop altogether? I'm only on Windows 10 cause of the fps increase I get in certain games. Should I go back to 7? What overclocking software should I use?

I used Afterburner, I increased the Power/Temp targer +20 (from 100), Core Clock +135, Memory Clock +325.

To all:

After doing the overclock above I ran Unigin Valley Benchmark for 30 minutes and it didn't crash. If you guys have any reccomendations such as OS I should use (7 or 10), Driver Version, Overclock speed (or not overclock at all), software I should use for overclock etc.

Thanks . Sorry for the late reply I never got a notification saying I got responses to this post but I'll be checking frequently.

 

there is a chance with win 10 the OC tool can end up writing to the panel

there's a thread in the main alienware section by @Mr. Fox covering it

I'd advise you use nVidia inspector its to my knowledge the only OC tool that's none not to cause screens to die

if you are happy with win 10 stay with it

 

Somehow this sounds like you're using a stock vBIOS. You should be using svl7's vBIOS, and if you can hold 1006/6000 with it being cool there you go.

 

if you can do a GTX 680's base clock then you're good and you'll get as close to a 660ti at best.

 

A 680's base clock should tear a 660Ti to shreds, though (reference anyway). 680s don't really boost much (1006 to 1058 average, even though the max boost is 1110).

 

I am using the custom vBios from svl7.

I just updated with the Windows 10 anniversary update and it killed the OS. So I had to do a fresh install WITH the Anniversary update and all is fine now, but I forgot what clock I had set it to, and it wasn't the one I had set above.

What one do you recommend?

PS: Sorry for the late reply, for some reason I'm not getting emails for replies here but I'll set it so when you reply I can quickly see.

 

If you're using the custom vBIOS you have 850/5000. You should be able to hit 950/5600 at the minimum. I say you could aim for 1006/6000 if you're not in a roasting environment.

 

Yeah I am on by default 850/5000. Yeah I'll OC to 1006/6000 as its really cold here in Sydney, Australia and my temps usually are low for GPU, but CPU temps are crazy haha.

 

I did + 1000 on MSI Afterburner and it caused my GPU to show artifacts. Am I using the wrong OC tool or did I do the OC amount wrong as if it is on 5000 by default isn't +1000 = 6000?

Thanks.

 

Afterburner probably reads memory in the 2nd amount. So try +500 and see what GPU-Z says.

 

Okay, I will try that thanks. Also when playing GTA V or any other intensive GPU game system freezes and driver freezes, this happens even when clocks for core are like +50, and mem is +100. Maybe voltage needs to be increased? But there is no option in MSI Afterburner.

 

Then try nVidia Inspector. I don't think I could make my cards crash with +50MHz on core and +100MHz on memory...

 

Alright, thanks! I'll uninstall Afterburner and try Nvidia Inspector.

 

What's the best program to use to test out if the clock is stable? Furmark I heard is not good for cards later than 6xx.

 

No real way. Unigine Heaven and Unigine Valley are decent, but not perfect. You could crash in some random low end game.

 

Okay, thanks! Will try on them for about 20-30min.

 

Nvidia Inspector won't apply clocks when I click "apply clocks + voltage"... I'll just go back to using MSI Afterburner and tweak and see how it goes best.

 

Oops it must've been from a driver crash even MSI Afterburner now won't apply the clocks. I'll restart and try again.

 

If a driver crashes like that, disabling/re-enabling your cards or rebooting the PC is often needed to make them work properly.

 

As soon as I set the clocks 1006/6000 I got purple squares (artifacts) and the laptop auto-rebooted. Voltage issue maybe? I'm using a 240W PSU and my 2960xm died so I'm using a 2760qm.

 

You should add voltage when hitting apply, yes... that's a far overclock. I said I couldn't make mine crash at +50/+100 even if I added no voltage.

 

How much extra voltage? +12.5? +25?mV Thank you.

 

780m with 1006/6000 most likely +-50mV

 

Okay, thanks man! I tried that +50MV, with those aforementioned clocks and it either causes the display to go black and come back (where clocks are locked down to 849/800 till reboot).

 

Okay, so I tried it again with +50MV, BUT +156/+500 and everything went okay. My memory is 2500mhz, idk why u guys said it is on 5000mhz by default. I'm confused now haha.

 

Silcon can make the difference. @thegh0sts used I think 62.5mV for that oc. Maybe lower to 880m boost clock 993MH. Most 780m manage that speed.

 

Oh alright, sorry what did you also mean by Silcon? I did a quick google search and it led me to some online CPU store.

 

Not all chips are equal. Some clock better with low voltage and other need more voltage for same Oc.

 

Okay, I get you. For me what works out best (for now, idk if it'll crash over long usage) but +156/+500 +50.0mV works perfectly.

Thanks for your help guys!

ghosts used 1020/6000, which is a harder push, and the +62.5mV was most likely for rock solid stability.

On the other hand, my primary 780M seems to need little voltage to OC but leaks more heat. I'm fairly certain I can manage 1110/6000 on only +87.5mV, and 1006/6000 seems stable at +32.5mV

My SLAVE on the other hand is the opposite. It needs +62.5mV for 1006/6000 I think.

 

My max stats are 1070/5560 on +87,5mV, Power and Temperature Target is on 110%. So you all dont change the Power a.T. Target?

Tip:
The best game to test overclocking is Battlefield 4 , anything wrong it already hangs.

In other games can be used to 1110mhz , but with the possibility of locking . The 1080mhz everything works fluid without crashes .

 

I have Dell precision m6700 with a used GTX 780m from someone else's Alienware 17. CPU is i7-3540m (will upgrade to a quad soon) and 8gb dual channel 1866 ram, CAS 13

Using svl7's unlocked BIOS, I can achieve a maximum of core 1100/Mem 6000 overclock. Power limit is set to 145% and core voltage is clocked at +100mv (resulting a 1.1v core and a 145w TDP?). My PSU is a standard GA240PE1 240W.

Playing Fallout 4 max settings for 1/2 hours and GTA V for about an hour, max temp is 80-ish. Rivatuner statistics reports a 82-90% tdp usage and GPU load is constantly 99% with occasional dip due to the weaker CPU. For GPU paste I use arctic mx4. I consider changing my stock thermal pad into gelid extreme one once the newly ordered pads arrive.

Fellow enthusiasts, even with the new better thermal pads, is it safe with 145% power limit (that push up the TDP to 145w+), 1.1V voltage and 1.10 ghz core clock?

 

High voltage can kill. 1.1V is a bit high for prolonged use

 

Thanks for your suggestions, what voltage would be a bit safer? How about +62.5mv or +75mv?

I did remember that my old 6970m on my previous Dell precision m6600 had a vddc of 1.1v probably AMD card and Nvidia card are built a bit different? But 6970m is built with 40nm process while the newer 780m is of 28nm.

What do you think of the power limit should I dial it down a little bit too?

 

I know several have run with around 1.066v over time without problems with 780m
