M15x GPU Overclock Thread

Sapphire Technology - TriXX Tweak Utility

 

and it wont make the whole comp crash lol?

 

also any specific instructions? or is it like ocing a cpu, just read temps and up voltage slowly?

 

Always increase your clocks only in small increments.

The max possible voltage of the 5850 is 1.15V (at least I don't know of anyone who had it higher and stable). But this will generate a lot of heat and is only suited for benching imo. With 1.05V or maybe even 1.1V you will be able to get very good clocks.

Watch your temps, and make sure you don't get artifacts (indicates instable clocks).

 

anyone know the max the 5850 can handle?

 

This is different for each GPU. In the most hardcore benchmarks with the 5850m (to find in the benchmark thread) the core got pushed to more than 1Ghz

For gaming you'll need to go lower because of the heat and stability, with adjusted voltage 800MHz core shouldn't be a problem. You have to test yourself what fits best your needs and thermal envelope.

 

right now im at 750/1050/1000 no increase of peformance, any help?

 

Start by increasing clocks to 750/1050 by moving the sliders (clicking on the bar will move clocks in 25 Mhz increments, with fine tuning using the +/- buttons), leaving the voltage at 1.00v initially. The attached graphic shows voltage at 1.05v because my vbios is flashed to 1.05v to permit voltage o/c to 1.15 using Trixx, which has a voltage adjustment range of only .10v. Many cards can o/c to 825-850/1100 on 1.0v-1.05v, but o/c capability varies. In my experience, you will need 1.15v to o/c at 900 core or above. As has been said, move in smallish increments (25Mhz) while exploring your card's limits.



Edit: The max reliable o/c my card can handle is 925/1150/1.15v at 3dMark11. In Vantage, it is limited to 915/1100/1.15v. Other apps/games have slightly different limits. You just have to experiment.

 

Of course performance will increase. Use 3dMark11 as your test bed. Run the benchmark at stock clocks (625/1000). Then o/c to 750/1050 with Trixx and click Apply. Run GPU-Z to affirm that the o/c was applied. Rerun 3dM11.

 

ok tried what you have and i saw a little performance boost in cod4, any other suggestions?

 

nothing but a huge spike in heat

 

Using one of the synthetic benchmarks is more effective to test the range and effects of o/c'ing because it provides greater consistency. Start at 750/1050 and take it on up. Using 3dMark11, my scores range from ~P2300 at stock clocks to ~3200 at 925/1150, a nearly 40% increase.

Edit: Well, unfortunately your card may have limited o/c capability. You have the tool and the process. It's a matter of trial and error from there.

 

got it! im getting over 300fps in insurgency with everything maxxed out.! buuuut temp gets to 80

 

In the abstract, temps in the 80's are not alarming, particularly if those temps are associated with memory or shaders. Core temps in the 80's is pushing the envelope, but remember, max temps that are simply spikes are meaningless. It is consistently high temps that are cause for concern. But it brings up a fundamental truth. Overclocking puts greater stress on the card and requires greater care. Good thermal paste and pads and regular cleaning become a necessity if heavy overclocking is utilized regularly. For most, the increase in performance in gaming is not worth the stress from extreme o/c'ing, but it depends entirely on the game and the o/c. I find 800/1050 gives a meaningful boost with minimal temp increases.

 

Hi All,

I am a relatively new M15x owner and am trying to do a little overclocking on my NVidia GTX 460M. I downloaded the NVidia performance tuner, however when I attempt to change any of the clock speeds and hit "Apply", I get an error popup that says my changes are invalid. So I tried the EVGA utility... when I change the settings there I can hit apply, but then the settings just revert back to the factory. My GPU is clearly underclocked at around 550 MHz and I'd like to get it at least up into the mid 700's range.

 

make sure you're not on stealth mode... happened to me too

 

How would I know if I were, and how can I change it?

 

Press the little speedometer touch button (the most right on the touch panel) It will be a little bit brighter when stealth mode is active... press it a couple of time and you'll see the difference.

Also there's a little app which helps you to see whether it's on and automatically disable it: http://forum.notebookreview.com/alienware/463382-stealth-mode-indicator-9.html#post6589020

 

aha! That did it. Thanks!

 

hi guys

i'm having some issue when trying to overclock my 5850m. When i try and overclock (any overclock) i get some flickering black images in game at first i thought this was my graphics card dying however i got dell to replace the card with a new one and i still get the same thing. i'm on the latest drivers (11.10) and i have used both catalyst control center and msi after burner.

if anyone has any ideas on how to sort this or what could be causing the problem that would be very help full.

thanks

 

What clock settings are you using for your 5850? Flickering black images can be tearing (triangular screen sections of various sizes, often black) which can indicate overclocking above what the card can handle, particularly memory settings, or insufficient voltage for the setting.

TriXX O/C Utility -- https://www.sapphireselectclub.com/ssc/TriXX/TriXX.aspx

 

this sounds like what is happening it happens the most at OC 750/1050 i've got it down at 725/1000 atm and that seams to have reduced the tearing only one in a while it happens at these settings. how can i increase the card voltage there is no option in amd's overclocking tools or MSI afterburner and is it dangerous to do so

thanks for the help

 

Use TriXX, the utlity I linked to above. Click on the Overclocking tab. At the bottom you will see a section and slider titled GPU Voltage. The max adjustment available is .1v. Move the slider to the right to 1.05v (shown as 1050) and click Apply. That's it, you've raised the GPU voltage. You can also set core and memory clocks. TriXX is the best and easiest o/c utility for the 5850M. 750-800 is where the lack of voltage usually reveals itself. Sounds like a perfectly normal 5850 in need of a little more juice.

With TriXX, the adjustments are sticky, i.e., they will remain active until reset within TriXX or reboot. You do not need to keep Trixx open after the changes are made and applied.

 

normal temps?



bluescreen after using amd gpu overclock tool 5870
not sure why ... i oc to 700/1000
usually i use msi afterburner... no bluescreen before... =-=

 

Those GPU temps are much too high, particularly with only a relatively mild o/c of 750/1050. You need to clean out the fans and vents and then apply new thermal paste to the 5850M.

Inap's famous Thermal Paste Guide will walk you through the process of repasting a GPU (and CPU) in the M15x. Download THERMAL PASTE GUIDE.rar from Sendspace.com - send big files the easy way. MX-4 paste is excellent -- easy to apply, nonconductive and highly effective.

 

bump:

I've managed to OC' my 240m from the factory settings of 550-1210-790 (cc-mc-sc) to 670-945-1474, I have tried bumping up my settings to hit 700 in core clocks but at 680 I'm unstable.

Hope it helps.

My specs are
Processor: intel i7 720QM
Memory: DDR3 4gb Corsair (2gbx2)
GPU: Nvidia Geforce GT 240M

 

My 240m on Acer was clocked to 698/1535/1013
All was ok throug 3 years of using all time oc'd gpu+cpu

 

So far I got my 5850 to 800/1100 @ 1.05v and stopped there. Helped a little bit in MW3 but I really need a 6990m! Would rather a 580m but so far no one has got that working in the M15X.

 

what settings is MW3 on with your 800/1100 1.05v? An oc of 750/1100 i am able to max the game, no voltage change.

 

I just played the game I have everything on extra and 2x AA. Plays very smoothly. I did noticed on the one night time level it dipped a lot but during that level is when I started overclocking the GPU. I just played the tank level and everything looked amazing and was easily getting 40+FPS maybe more. I'm only at 1600x900 though.

 

There area few settings that you should take off of extra and put it to normal or native. Extra actually stretches it to fit the screen, where as normal/native puts it to your proper native res without stretching the image. I've tried both and normal in fact does look better and sharper. That's weird, on 750/1100/1.0v its maxed out on 1080p (not extra, but normal), max temps were like 66-68c, and no hiccups. Gfx cards are so weird.
