Has anyone tried to overclock the GTX 765m in these at all?

From what i understand the GPU still has some limits on the thermals, and i'm not talking about increasing the voltage.

Has anyone tried to bump up the memory clock a bit? We would likely see a huge (10%) jump in performance if we could bump the memory clocks up on the GTX 765m from 1000Mhz stock to 1250Mhz. Likely it might raise temps 2C too, nothing much, i get mine today after work around 6pm EST. So if anyone can indulge me while i wait eagerly i'd appreciate it

Thanks!

 

For sure, you can pretty much max the values allowed with Afterburner, i haven't tried benchmarking it though just yet, but it does get some nice boost in games.

 

Thanks buddy, when you say max, i know the Core maxes at 135 mhz, does the memory "max"?

 

It sure does. ANd had no issues in-game, but I'll do a run of 3DMark11 and 3DMark and see what happens.

 

Gah, too small, can't read, such a tease

 

it's set to +135 core and +1000 mem, but now that I see that, I'm thinking it cannot be right.... I'm using Afterburner Beta, let me do a run with those numbers and compare to stock.

 

If you go to settings and have it display, or run GPUZ it will tell you the clocks its running at before Boost 2.0

Edit: +1000 Memory would be insane, it would literally be double and be 128Gbps instead of 64Gbps.

 

I can't do +1000 but I do +750 mem and +135 core easily and get 4931 in 3DMark11 and 2984 in 3DMark firestrike. I have a feeling the core could go even higher if it were allowed.

 

OMG DROOL.

96Gbps instead of 64Gbps, amazuhing. Now feeling even better about this purchase because i should be able to get 60 FPS on BF3 at ultra Minus HBAO. Which doesnt affect my Gameplay.

 

I have no problems with the Core @ +135, but can't go over 500 on memory.

 

500 on the memory still takes you from 64Gbps to about 79Gbps.

Which for our resolution is a substantial bonus.

 

I go core +135, Mem Clock +250 on mine with no issues. When I pushed the Mem Clock even further I get nvidia driver stopped working and recovered error. At home I have my Blade hooked up to an Asus 24" 1920x1200 16:10 IPS Monitor and with stock clocks I can play League of Legend at max settings with solid 60fps. (my main game)

 

Thanks for the help guys, gave you all rep, there isn't enough information on the internet about overclocking this machine. Could use a good thread about it.

I got mine today and it is an amazing laptop, best i've ever owned and i've had plenty lol.

 

My feelings exactly!

Check out my Amazon review, I was compelled to write one, this thing is amazing

Amazon.com: Customer Reviews: Razer Blade 14 Inch Gaming Laptop

(my Review is Alex Rain's)

 

When i tried overclocking mine, either 135 mhz core OR 500mhz memory, 3d mark 11 just crashes

Edit: Its like the gpu doesn't switch from the 4600 to the 765

 

Overclocking is total luck of the draw unfortunately. I got instability when bumping the memory by 1000mhz, which some people have success with, but if I drop to about 700 everything runs fine. That said, I just run mine at stock... I was only curious how far it could go.

 

sherifone is absolutely spot on. With every manufacturing process, there is a statistical spread (usually Gaussian) which determine the upper and lower limits of the chips' capabilities. Manufacturers rate their chips and control the manufacturing process carefully with their target objective being that most of the chips in a particular batch will pass the (guaranteed) published specs. In other words, ALL the chips sold WILL work at stock values, or you get your money back; some can be pushed a bit higher, and some a lot higher. If your particular chip works at anything higher than stock values, consider it a bonus. A lucky few might get fantastic results; others will not be able to go beyond the stock values at all.

 

Well said! It is the same when people over clock their CPU's in desktops. One may be able to push his 4770k to 5ghz, where the guy next to him can only get 4.7ghz out of his.

 

I cant get my core clock to change at all. I can move the slider and hit apply, but it doesn't change the core clock. I can get the memory up 600 mhz stable, but it only adds a couple hundred points to the score. Anyone actually getting a core clock speed change? How?

ps. The default memory speed is 2000 MHz, not 1000 MHz... so I can get mine up around 2600 MHz.

 

Score doesn't really matter. Since they are lower settings your memory clocks wont affect the score as much as it would affect bf4 with aa on. Its a substantial gain.

 

Quick question, if I do over clock, how does this affect the switchable graphics? Will my blade be stuck on the 765m or will it still switch back to the 4600 for general use? And so you guys are running 1035mHz on the core and 3000mHz on the memory? Any additional cooling being used?

 

So your core clock actually changed? How did you get this to happen?

 

I would apply it each time before running a game or whatever you need the gpu for.

 

Huh, so what levels of improvement are you guys seeing from your overclock? I'm debating if this is worth the extra strain on my system or not.

 

You won't even notice a temperature difference.

 

Okay?, I've played around with it a bit, just doing +70 and + 500, leads to an extra 5C*, 71*C to 76*C. Its gives about a 10-15% FPS boost which is nice.

 

That 5C could be different depending on the game /cpu load or just a change in temps in the room.

When playing bf4 i go up to 85C on the gpu, then the fans spin up, then back to 82C then rinse and repeat.

When playing GW2 it doesnt' go above 74C. So make sure you play the same game same settings etc.


This laptop may have different fans but they both share the bezel as a heatsink.

 

Greetings Razer Blade owners,

A few days ago a friend of mine gave me his newly bought Razer Blade to set it and overclock it. He is mostly a Mac user who loves casual gaming, and most of all portability and mobility, as he's always on the move. Buying a bigger laptop or a desktop wasn't an option for him, he needed something small and powerful, which is why I advised him to buy the Razer Blade. After trying it for a few days I believe getting this notebook was a very smart move.

I wanted to share what I have been able to achieve with overclocking the 765m. So far, I've been able to push the GPU to 954mhz core and +500 on memory with Afterburner 3.14 beta. I agree with those here who suggested that OC the CPU is not advisable, considering it gets quite hot when playing CPU-bound games, such as Crysis 3, Metro LL, etc. With this GPU overlclock I was able to play Metro LL using native resolution, on very high, physix off, no AA, vsync off, and see an average of 50 fps (!!) with occasional drops never lower than 43. With graphics set on high and adavanced physix ON, it staid between 55 and 60 fps. It was butter smooth. I think this is quite an amazing achievement, considering that this a very small laptop and Metr LL is quite the demanding game. CPU-wise, in game I saw a stable 2.9Ghz on all cores and temps ranging between 75 and 80C. I will still have the computer available for the time being, until my friend comes in a couple of weeks, and in this time I will try to find the sweet spot between maximum overclock, temps, and stability. By the way, in order to improve air flow I placed Laptop Lifts Rubber Feet under it and temps under load dropped a few degrees, which never hurts.

I have my AW18 with its dual 780m SLI and Haswell overclocked and all, yet I find myself playing on this little Razer beast more than I would admit on the Alienware forum, so don't tell them

This computer is a little jewel, and I will definitely miss it, once my friend will get it back. I can't congratulate enough all the people in this forum that are the happy owners of the Razer Blade.

 

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

 

Does this void your warranty?

 

Yes, overloclocking hardware does by definition void warranty if it becomes the cause of damage. Overclocking exerts an excessive stress on the hardware which, while it improves performances, may damage components. With that said, many people overclock around here, since they can appreciate the benefit of increased performance in game or when chasing numbers. When it comes to overclock for better game performance it is not necessary to push the GPU too much. If you are getting 71C under load is not a bad temperature at all. You can push it further if you think you actually need it. But you need to find a happy medium performance/temperature/stability. Decreasing the GPU voltage might increase its instability, depending how much you push core and memory. I advise you not to push GPU memory beyond +400. Only benchmarks benefit from memory higher than 400. Besides, pushing memory shorten the life-span of your GPU (as overclocking in general also does). Leave the memory around +300/350 or even at 0, and focus on increasing core value by +5 or 10 each time and test. Make sure temps are in check, and that it is stable with new clock. If you're not already, consider elevating the computer, working in a cool environment, and acquiring a laptop cooler.

 

Thanks for your reply .... I was talking about undervolting the CPU not the GPU ... if i did this can i increase the clocks further ?? right now, anything > 500 on the Mem clock causes throttling ... my core is maxed to +135 ... i have used nvidia inspector on the R2 (GT 650M) and with that i could easily push the core from 835 to 1100 (way beyond the limit provided by afterburner) and the MEM to +1000... but somehow inspector doesnt seem to work on the GTX 765M .. any insights on this ?

 

I can't quite get to +750 mem, but can get a stable +730. Core is happy at +135 and like other I'm sure could do more.

3DMark Firestrike - 2955 :

Real world differences, Grid 2. Nvidia optimised settings, no GPU overclock :

And with above overclock -

That's a ~10 FPS increase ~10% performance improvement.

Not bad!

 

Can you post temps with and without the OC? and do the fans get any louder for longer periods of time?

 

I'm wondering about overclocking voiding your warranty. I've purchased an extended warranty, and I really don't want to throw my cash down the drain. Is it possible to detect overclocking? Or is it kind of like flashing a ROM on an android phone, you just kinda go back to stock. I've always overclocked on my desktops I've built, and I've had no problem with the process itself, but the technicalities behind overclocking with an extended warranty need a bit of clarification .

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!
