Overclocking the 7970M

Hi Guys,

I recently got a Clevo P170EM with the 7970M. I have already gotten the card to 940/1500 using afterburner on stock voltages and was wondering what others are getting for the same card/voltages and what drivers they are using. I'm on the 13.5 beta 3 drivers and would happily change if other drivers gave higher over clocks.

I've been running 975 and 1425 for a while now with no problems. Never changed voltage. 3dmark score is consistently around 7600+. I'm running 13.5 beta 3.

 

Been running 1000/1500 when I need the extra oomph. Voltage moding can only be done old school style AFAIK : Graphics cards - Volt mods / pencil mods 56K warning! - Overclock3D Forums

Cheers!

 

Thanks for the replies. I will try those setting but, already gave 1000/1500 a go with Crysis 3 and the laptop said NOPE.

 

The limit varies a lot from card to card. I'd also advise you to try different settings. Some games may benefit from higher core clocks (like 1030/1200), others from high memory clocks (960/1560). Keep an eye out for that increased temperature

 

Test core and memory individually to get an idea of what each can do.

 

Temps don't seem to be much of an issue. At 931/1500 playing tomb raider it chugs along happily at 65 degrees.

Just I read a few posts where people had the 7970M running at 1000/1500 which would be awesome to have myself but even at the current OC's it's still a very capable card. Maybe I will experiment with custom voltages etc later on but for now best money ever spent!!!

 

Currently I'm running 13.5 beta 3 drivers, and they have the best overclock ability so far. Performance vise it seems same compared to lets say 13.4 whql. I can now overclock to 1070/1600 on stock volatage, but thats just for benchincg. I foud a good compromise for gaming at 950/1450 for gaming which I'm running 24/7 with temps max around 80.
Heres a 3d mark run with 1070/1560 -- 8013 pts on GPU

how could you oc mem pass 1560?

 

In my humble machine (g73) I am getting [email protected]/1378 and its solid like a diamond!!! Temps are about 78~81 on crysis 3!

Overclcok to 1560, apply. close MSI afterburner, then open again and you can move the sliders further..

 

this does not work on my 170em. already tried many times. what version af u using?

 

I'm using the older MSI afterburner 2.2.1. Maybe its becouse of that. I remember that in some older driver releases I had issues with the never MSI afterburner so I just kept this one and its working fine. Except fot double fps readyn on some games ( max payne, crysis 3, metro: last light). If you wont find it on the web send me a pm, I'll send you the instalation paccage

 

i used 2.2.1 before and now 2.3.1. all failed. really no idea
i am trying trixx and it allow me to slide further but when i apply it shows this

 

Hi try that:

ULPS is controlled via a registry value named "EnableULPS" located under the "HKLM\SYSTEM\CurrentControlSet\Control\Video" key, it can be disabled by setting the value to 0 or enabled with 1.

Change value to 0 and restart your laptop, see if you can change values now.

 

no luck. any idea with other key?

 

or any other key?

 

This one:

 

this one:


Just click on the top computer to search throu everything, hit CTRL+F and type in EnableULPS and it'll find it

 

change registry and restart and set. failed!

 

what is funny is that ulps is really disable (the fan cooling 7970m spin up occationally when 7970m is not in use) but trixx stil show the message

 

Thanks for the replys guys. I'm wondering if the fact my 7970M is the 2gb VRAM version that comes with clevos is the reason I can't push the clocks past 940/1500 without either bluescreening or the display drivers becoming unresponsive? At any rate even at 940/1500 I was able to play crysis 3 with everything maxed bar the textures ( had to run them at high to get 30+ fps).

 

There is not a 4GB 7970M AFAIK, but it would make no difference to the clocks.

Every single chip every produced has its own characteristics depending on hundreds of different factors over the massively complex process that went into creating it.

 

Definitely not. vRAM largely is meant for storing the framebuffer, and 2 GB is ample for gaming and even some professional software.

 

4GB is needed in multi card, multi display setups

 

and work / XCL? ,

xcl doesnt work for me

 

No, that command wont work on switchable (and professional) cards.
