Overclocking 8600M GT

I've just got my new inspiron 1720, and have decided to start overclocking it. I have 165.01 drivers, and am running Vista 32-bit. I am able to get a STABLE 685 Core / 535 Memory overclock from the default 475/400.

What Vista 32-bit drivers are best for this card?

Also, people should post what overclock they are getting, with what notebook, and with what driver version.

 

don't run at 685 core...

 

why not?? it isn't getting too hot. And i havent seen any artifacting.

 

i was running 542 core and 800 memory without trying too hard. its very stable at those clocks. it could go considerably further- especially the core.

macbook pro

i had to use the 101.24 drivers to do the clocking because i am using windows xp and the 160 series drivers prevent over clocking in xp. in vista you can play with the clocks with whatever drivers you want, it seems.

 

how the heck did u get 800 memory? is that the gddr3? my memory clock wont go above 540 without artifacting!

 

yeah i think he has the gddr3 version which starts at 700

 

yeah cmstyles is correct. the macbook pro, asus g1s/g2s, and maybe a few other notebooks have somewhat faster memory. the macbook pro is clocked at 470/635 by default. the others (i think) are 475/700.

still, i dont think my core clock will go up to 685. thats a MASSIVE increase. i can't imagine that it is safe at that clock...

 

Lol i was going up in about 3-5 mhz increases, looking for artifacting. I actually didnt get any artifacting up until 690 mhz. I dropped it back to 685, and played HL2 Lost coast at max settings and max res, then I also played Lost Planet (DX10) for a while. I didnt have any problems, and the card wasnt even getting that hot.

 

What are your computer specs?

 

2ghz core 2 duo, 256mb 8600m GT, 17" HD screen, 2gb ddr2 667mhz, 5400RPM 160 gig hdd

 

Thanks!, what kind of fps did you get on HL2? If my vostro can play HL2 on max I will be one happy camper!

 

Well, I want to overclock the 8600M GT in my 1520.

Can someone guide me as to how/which program to use and what drivers are the best for Vista 32-Bit?

I have RivaTuner if that's what I need. If I need something else, please tell me.

 

Try atiTools... That's what I used on my desktop to OC my 8800.

 

stick with riva tuner. it is all you need. its not as simple as atitool but its much more powerful. (its not that hard either)

check out www.tweakguides.com for an explanation of overclocking i think a guide to riva tuner.

 

Well if you want to overclock you have to use older drivers which cause alo tof crashes and such in games. If you want to use the newest drivers they do not allow you to overclock.

 

above is true for windows xp only, i think.

apparently vista 160 series over clockers are abundant.

 

If you want to overclock in Windows XP with some newer drivers, use NGO's 158.22. I'm overclocking just fine with them.

 

No its true for vista too you can't overclock with the new drivers such as 163.11.

 

any idea why whenever i try to go beyond 470mem clock i wil get an error which says nvlddmkm.sys has stopped responding and has recovered successfully? i'm using the 5920g clocking it at 600/470, i can up the core clock but not the mem clock any higher, this is frustrating, my tempts are al stable, just that i get that error and it goes back to 169/100, unable to be changed til i restart the comp.

Btw i'm using 158.45 and if ANYONE can provide a solution on this i'd be most grateful

 

I have same spec as you. What program did you use? because I can't get my OC to stick or stay. It would go back to default with ntune. Are you using atitools? ANd the driver your using is old, I believe because of the release date on that. I'm using the 158.36 because 160 will not OC . I'm hoping they make better drivers for these because they have potential.

 

I used ATItool to overclock

 

I just installed 158.36 and have no problems OCing with ATItool

 

yummy, the same spec 1720 i ordered should be coming soon, hopefully mine will get near that, can u get some before and after default 3dmark06 settings scores?

oh and whats the temp at?

 

I just ran 3dMark06 @ 1280x1024, everything default, and got 3951 marks. It looks like my temp barely even got to 70C after it was done.

 

I thought you said that you overclocked the GPU on vista with the new drivers, roswell.

 

I only use the 101.34 stock drivers, and i cant OC with nTune, i am furious. I NEED to know this... what drivers work will all games, allow OC, and provide performance boost, and digital vibrance for the fun of it. It MUST work vista thanks..!!

 

After running 3dmark 06 my factory clocked (475/400) 8600m gt reached 80 degrees C...

 

I did overclock my gpu on vista, with 165.01 drivers, and also 158.36. I havent noticed any problems with these drivers (158.36 currently), OC fine and stable for all the games i play.

 

My Asus G1s sees 80 degree temps all the time with the factory clock (500/700 I think).

G1s' in general run pretty warm, some computers are just that way. Those temps you see may be normal for your machine.

 

Ntune is useless for me. No matter what speeds I put, it says it's failed. Just use rivatuner.

 

What do you guys use to see the temperatures?

 

Use rivatune.

I hear some of the 162 and 163 drivers have been giving a 5fps increase ovr stock, is this better than overclocking a 158.45?

 

I just overclocked my 8600m gt from 475/400 to 555/455 on 158.45. I got a slight improvment in performance;

3dmark 06 score (1280x1024) before overclock was 3000 and after 3300.

CSS stress test all settings on max, native resolution, filtering x4 and AA x4 before overclock 51fps and after 58fps.

Also got an increase of about 4-5 fps in dark messiah.

I would really like to overclock a little more but there was a point where my GPU reached 89 degrees C so thats it for me .
I might try some of the 162 divers and see if those work better.

 

You should really up your memory some, a lot of room there for a lot better performance.

These notebook cards are built to handle lots of heat, but mine isnt reaching near that hot. Are you on a 15" or 17"? Also, a dell?

I wasnt able to OC with any of the 160 series drivers, but GL

 

I've never overclocked before, so I'm a little hesitant. What would you say is a safe rate of overclocking, yet with a good power boost? I'm running an 8700M GT at the moment, and I have an external cooling device that helps a good deal as far as heat goes. I just did 625/700 and it ran nicely, but I'm unsure as to what would be too high.

 

well if i got my 8600M's core to 655, id assume that you should be able to safely get your 8700 to the same or a bit higher without worrying.

 

hmm... nearly same specs as me... But I cant play lost planet (DX 10), even at lowest setting it still suffer a lot of fps decrease after I played it around 1 hour

 

Im on a 15.4" Zepto Znote6624.... obviously it has crappy cooling.

Anyway I changed the clock to 535/490 and got a further improvment in performance and the temp is about the same. New 3dmark 06 score 3392.

However I discovered a problem. I selected the "apply overclocking at windows startup" option in riva tuner and whenever I restart my laptop I get the following error message in the boot up screen:

"ERROR
0232: Extended RAM Failed At Adress Line: 22
Press F1 To Continue"

When the laptop finally boots up the card is back at its factory clock; 475/400. I get this error message with any change I make to the card clock.
Any ideas?

 

I wouldnt adivse to overclock on boot-up. I just turn it on whenever i want to use it.

 

running at 600/515 no problem. Probably not going to go too much higher.

 

I can't seem to overclock with RivaTuner202. It seems as if my speeds are not even detected when i am in the System Tweaks --> Over****ing tab. I select detect and nothing happens. I have the 158.xx drivers & Vista. Rest of info in sig.

***EDIT****

It helps if you select the right adapter...

 

roswell, I still dont understand how you managed to OC on 165.xx drivers on Vista? I hear that anything over the 150's dont OC at all?

 

The 163.xx drivers are new. The 165.xx drivers are ancient. He's running old, old drivers.

 

Here's my guide to OC 8600M GT MXM type card(BIOS LEVEL OC)
Aspire 5920: VGA Bios modification/flash/restore guide

I Tested my guide with Aspire 5920 and Asus C90 But I'm sure same method goes to all the 8600M cards with MXM module

 

i seem to be having a little bit of trouble overclocking my 8600m gt, i have both rivatuner and ntune installed. i am running the 158.36 driver with windows vista home basic, and my gpu is currently idling at 53 degrees celcius.

Core Clock/ROP Domain - 297 mhz
Core Clock/shader domain - 594 mhz
Memory Clock - 199.80 mhz

In rivatuner when it tries to find out my clocks in the overclocking area, nothing happens, and in ntune i cannot drag the sliders to overclock.

im trying to overclock because i can only play the MoH:Airborne demo at almost lowest settings

i have vostro 1500, c2d 2.0ghz. 2gb ram

thanks,

 

Look up one post saunders....thats what your going to have to do with drivers 158.36 and 158.45 up.

 

Saunders has more pressing issues than overclocking. He should be able to run that demo just fine at 1280x1024 or lower resolutions.

 

Hey swoleky2k how's my guide??Is it good?? Or need More info??

 

I havent read it entirely but from what i looked over its very good. Unfortunately, hardly any one will notice it....

 

ya can i repost it here(Gaming Forum)
