9600m GT msi gx620 unstable

Direct repost from this other forum

Good day. I am, for one, a total newbie at this overclocking thing and in need of help.

The laptop:

MSI gx620x
Win Vista Ultimate 32bit~
p7350 c2d processor @2.0ghz
9600m GT ddr3 [stock at 500/1600/1250 but everyone here probably already knows that]
3gigs of ram
MSI 1462 board [at least that's what GPU-Z said so]
My driver is forceware 179.48 downloaded from nvidia.com



Breakdown of what's happened:



I downloaded 3dmark06 last night [about 12 hours ago]
I started OCing 5days ago roughly by following this guide.

I followed his procedure and copied his clock/shader speeds at 625/1550 while leaving the memory clock untouched.

Worked fine for 2 days then it started screwing up by random monitor black outs with a hard lock on my system, only way to recover is a forced shutdown and start it up again or World of warcraft suddenly crashing but leaving my system workable like when raiding, I WoW screen locks up, no fatal error, have to force shut down via task manager.

so with that I thought about reducing the OC levels a bit. I ran with 600/1500 core/shader and still not touching memory clock.

I still crashed from time to time but a lot less frequently.

I reduced OCing a bit again. down to 590 core and back up to 1550 shader. before doing this - I did a quick test for the shader, pushed it to 1550 wihle leaving the core clock on stock speed [500] and ran it on 3dmark06. no crashes and what not. not even a black out.

So now I'm running on a 590 core with 1550 shader and I ran 3dmark06. I got a monitor black out with hard lock. I read somewhere that the voltage of my GPU may or may not cause the whole crash/black out thing but I'm not too sure about it and I am frankly afraid to do it without the opinion of someone with proper know-how on the matter.


Summary of what I know:
1st is to OC shader until unstable then drop down to desired level
2nd is to OC core until unstable then drop down to desired level
3rd is to OC memory [but I don't really plan on doing that]
4th is to monitor system heat
5th is monitor stability.

my peak on my most unstable OC came up to 77C and that seems fairly okay. at least I'm still below 80C.



I'd appreciate any kind of help anyone would have to offer for this.

 

I suggest getting these drivers:

http://files.laptopvideo2go.com/Dox/Vista/Vista_182.46.exe from this page http://www.laptopvideo2go.com/forum/index.php?showtopic=23484

and overclock your GPU to 550/1600/1650. see how that works

 

copy that. I'll see how it goes. how long should I test this? Will a few hours on gaming do? like 1-2 hours or so

 

the new drivers should give increased performance and the new clocks are based on a "ratio" of my clocks. i went from

530 to 700
799 to 1100
1300 to 1900

those are sick improvements. and the core was the least increased. the core is usually the 1st thing to crap out.

and you can test this with either furmark or occt. run either for an hour as well as regular gaming. make sure you monitor temps with hwmonitor

 

I adjusted the first clock speeds you gave me and came up with

570/825/1550 including new drivers.

no crashes after an hour of wow.

willing to push for a bit more. my goal is simply just 600/850/1550. I'd take 625 as a whole bonus should it work. oh and would I need to up my voltage? I'll research on how if I *have* to to get a stable desired clock.

 

@Dude55
Hm... interesting speeds. Did you increese the voltage to do that?
O, your cart is 9700M GTS? It's not the same as 9600M GT. Yours is using G94M core and both 9600M GT and 9700M GT are using G96M core...

@Bele
Use my clock rates They are stable. Also see GPU link in my signature

 

genna what is your gpu running temps wise under load?

 

That's why I wrote to click on the GPU link in my signature. There are temps, 3D Mark test score... but anyway, I wrote somewhere else, I'll write it again. My highest ever seen temperature untill now was 83C. This was after 4 (I think, or may be more) hours playing Crysis.

 

@genna

I wrote somewhere in my original post that that clock speed is what I'm going for but it started crashing or blackouting on me. Like when I'm playing a game or doing 3dmark06 - I get a monitor black out and a complete system lock. only way around it is a forced shutdown [the holding the power button kind]

 

When you were OCing did you consider that you have to keep the ratio between shader clock and core clock. It must be 2.5. See the defalut clocks.

 

yes I kept the ratio and it was unstable. 1500/600 = 2.5 [OC goal]. 1250/500 = 2.5 [stock]. 1550/625 = 2.4 [shouldn't hurt the ratio that bad right?]

I read somewhere that you first push the shader until unstable the comes the core to a max of half the shader's c\lock then the memory. do I maybe need to adjust voltages for this one?

Side note: MSI gx620 has a fan like any other laptop but why can't any monitoring software [riva tuner/speedfan/gpuz/NHC] detect this? Would like some input on that as I'm also looking to run my fan at max speed at all times. I do know it'll be noisy or something but that's not really an issue. I kept my old laptop's fan running at max whenever i turn it on.

 

I think (suggest) that voltages should be changed if you try to OC it more than 650MHz.

It's like mine, so I think not really.

 

so I upped my clocks to 575/1550 from 570/1550. no longer than 30 minutes into gaming and it crashed. I conclude 570 is my vcard's peak [unfortunatly. why I'll never know].

I decided to stop the OC at a 10% shader/core increase for safety and slight performance increase.

current clocks are at 550/800[1600 effective]/1375 - core/mem/shader

I'll never know why my card's core limit is as low as this. any ideas?

 

Could be down to drivers/voltages, you gota play around with the clocks until you get a nice mix.

 

I guess my game was messed up. WoW kept crashing even on the slightest overclock so I went back to stock settings and stock drivers! guess what, it still crashed! [wow specifically]. as it turns out I had to reinstall it [delete folder] and it stopped crashing. I'll running on +20% increase again for today. I'll see if I get a black screen of doom or something [that's really all that freaks me out.]

 

stable at 600/800[1600 effective]/1500!! I am a happy man

edit:

I take it back I just got my monitor black out but audio was still there, after a few the audio died. it just.. died. no system lock up or memory crashes where the sounds would repeat in spammy fashion.

This also happened several hours after I installed dox's drivers [went through a whole day of playing 3 different games and no crash/black screen until I installed dox].
