Overclocking 765m on 2013 14 - possible?

Hi everyone,

I've been trying to overclock my 765m since release, and, regardless of driver or firmware revision, full-screen games (and, particularly, 3dMark11) cause my core clock to drop down to 405MHz within seconds. However, running a windowed app, such as Furmark, causes no such issues.

Has anyone experienced this? It's clear to me that this card has at least some comfortable overclocking headroom, but I haven't been able to get it to stay. Any ideas or tips would be appreciated!

this may fix your problem

 

Afraid not, but thanks.

Really, though? No one else has noticed this? It's pretty obviously something deliberate. I'd be extremely surprised to find that this doesn't happen with everyone's machines.

 

It may be lack of power source, the AW14 is intended to work at the stock clocks, haven't seen many people trying to overclock it or success stories.

 

Have you tried to undervolt the cpu? this would reduce power consumption and load temps hopefully giving you more head room for the gfx card. I undervolted my 4700 by -100ma with intel XTU and it knocked about 10c off my cpu load temps

 

So would a 240W PSU work for overclocking? I have one left over from my m15x

 

I have a 240w PSU from my m15x, I can try that for added juice if someone wants to refer me to an overclocking program. I haven't oc'd anything yet

 

Furmark showed my GPU speed throttled -490something MHz. This happened in fullscreen tests as well as windowed mode. I'm assuming it's not happening while playing actual games but will need to wait till tomorrow to find out.

 

Hi All..... I have an ALienware 14 ... can anyone please help me overclock the GPU ??? right now im doing +135/+500 on MSI afterburner with driver version 331.65 ... im getting temps of 71c with discrete mode .. i want to push this further as with this OC i saw a huge improvement in FPS in batman arkham origins ... anyway i can do this by not significantly increasing the temps ?? undervolting the CPU perhaps ?? also, does nvidia inspector work for this driver version ?? Request you all to please upload screenshots of ur OC setup .. thanks a lot

 

Guys, the 14 isn't power bound. With my 4700 undervolted - 85mV at 3.4Ghz across 4 cores, Gpu @1ghz/5300ghz vram during 3D mark11 power absorption doesn't exceed 99W...measured at UPS Outlet (capable of output 900W). Imho AW team could have stuffed a 770m and the system would have handled both under the power consumption point of view, than the thermal one

 

I think the 14 is at its thermal limits even at stock clocks. You can squeeze a little with msi afterburner but the small gain you get versus the heat it produces is not worth it in my opinion. I like the the 14 performance, but when you get use tot he 18 with ski 780's and a desktop it starts to show its slight lack of power. It handles BF3 fine and bf4 fine. but I am a performance nut and need higher fps in bf4 so I dropped the res on my monitor a little to keep the setting on high to get my frame rates i want.

 

The laptop is not at its thermal limits, it just throttles due to Dell's settings. Clevo's W230ST runs much hotter than the Alienware 14 and doesn't throttle. The GTX765M can run much hotter than it's allowed to by Dell. I can OC mine +135 core and +400 mem and it doesn't throttle unless I restrict airflow. While sitting on a desk or table, it runs at about 65C at those settings with a 23C ambient.

 

I'm in the same boat. Without touching the voltages, I'm often running into a situation where it drops to P8 (safe mode) and locks the core and mem at 405 MHz. I assumed I should have had lots of headroom based on the temperature, but I'm also occasionally getting driver crashes, which leads me to believe that my GPU can't actually reliably run at 1035 MHz at stock voltage (the real reason for it dropping to P8). I guess that means I lost the silicone lottery.

The good news is that with the voltage increased to 1.175mV using EVGA Voltage Tuner (part of Precision X) it seems to run fine at 1035/2200 although a bit hotting (getting up to 73 degrees).

 

OC Results with modded vbios

Those are my OC results after flashing SVL's vbios. The GTX765M is much better than Dell let's it be. Take away Dell's restrictions, and it's quite a card. My card only runs at 72C, even at those settings.

 

What kind of voltage do you have to run to obtain those clocks? Played any games with it and is it stable?

 

1.1V and stable.

 

Sweet, gonna try flashing my -4 to squeeze some extra percormance. I'm have with my 18 so I'm not going to flash it right now. Just haven't had time I have 4 big projects going on right now for work that is eating up my spare time.

 

Hi There .... I have tried the same clocks as you ... but for me it is stable at 1.15V. However, my 3dMark11 score is 4577. It is lower than expected.
Any idea what the issue is ? I too have flashed using svl7's VBIOS mod

 

First install and run the program in the link below if you have an Android device. It'll let you watch temps and clocks real time from your phone when you're benchmarking. It's a very cool application that is great for benchmarking and gaming.

Try rerunning 3DMark11 and watch the clock speeds on you phone (if not, you'll need an OSD of the clocks, EVGA Precision does this IIRC). They'll slow down during loading screens (that's normal), but if they ever lower while benchmarking, something is causing it to throttle. Whenever it throttles, check the temps. As temps go up, so do voltage requirements. 1.15V may be stable at 75C, but not at 80C.

Try lowering your clock speeds a small amount if throttling continues. Keep lowering them until throttling is gone and that's your max stable OC. You may have lost the silicon lottery.

Since your results are lower than my runs at +135/+300, I can almost guarantee you're throttling.

 

Thanks for ur quick reply Wattser93 ... I want to know how accurate or how judgmental these benchmarks are coz i do not get throttling while gaming ... i experience throttling only while running benhcmarks ... moreover I have undervolted my CPU core so even with OC my GPU temps do not cross 69.

Ur clocks (i.e. +250/+300) work perfectly fine while playing AC4. I have also read in some forums that the heatsink compound takes about a few weeks to months to adjust which can lead to more OC.

 

The benchmarks are reliable and repeatable. Most of my runs are +/- 20 points when running identical settings. You're definitely throttling while benchmarking, and some games will likely cause throttling as well. Just keep an eye on things and if you notice throttling reduce the clocks on the GPU until it's stable.

 

i modded my 765m. i have the asus g750jw..i got really good scores on 3dmark11 my score was around 5584 or something like that.. 1300 mhz core 6088 mem and 1175 voltage...but that didnt last long because i came across the throttling problem..it kept throttling in the game i lowered it lowered it lowered it and i ended up with stock oc where it doesn't throttle..i tried undervolting cpu still no help gtx 765m loves the throttle..the god damn card...tried so many things on vbios changed master voltage tdp limit this and that...no luck unfortunately..i don't know if its a voltage problem or boost problem or something else..as soon as i go pass voltage 0990 it starts to throttle...hope someone figures a fix for this.

 

Looking forward to downloading and running on my AW14! (once I reach the minimum post threshold on the forum!)

 

overclock GTX 765M together with 4700mq 1600mhz 16gb ram 14 inch laptop Firestrike 3DMARK 2896 points with 9526 physics

View image: GTX765 M BEST STABLE OVERCLOCK

gtx765m best stable overclock all in one screenshot.

extra answers which are not available in screenshot;

i opened the case and put another 12 volt core 2 quad extreme fan on top of the fan. it is on the hdmi side of the notebook on the back corner, focus your fan on this place, or leafs of fan.
you can never achive 9500 phsics unless you do this.
if you limit your cpu to 3ghz case closed, 3.1 case open you can hit 8400
no easyly available laptop cooler can cool alienware ! just open the case and put it on a higher level than table op put it like a open book to the side with open case.

you can't stop throttling on overclock unless you lower the degree of the chip.

core 2 quad extreme had a bios setting which you disable (actually disable them all) and you can get rid of throttle nightmare

stop using other overclock softwares and flash v bios adding
nvflash -4 -5 -6 biosname

with -4 -5 -6 it force overwrites old bios. in my case it said it is different id so it can't

what i share is a 1 week work please tumbs up!
