dox drivers comparison

im currently using dox 181.22 perfomance nvidia driver (sleep function works yay!! ) and is fairly happy with it. I tried to upgrade to the Dox 185.20 but it doesnt like to be overclocked (freezes when i pass 950mhz memory)

is there any huge difference between these drivers?

 

Not a huge difference...

+250 MHz on the memory?!

wow, hope you have a sick cooling system

 

his is GDDR3, so i think the memory clocks are higher at stock.

 

stock memory clock is 600mhz. I was able to hit 1100 mhz without artifacting (tested with rthdribl for 6 hours) but lowered it because the memory is passively cooled.
also does anyone know if i can put hitsink's on the gpu memory chip?

 

My God an 8400M GS pushed that far is kind of a nono.

Do you have a cooling pad?

I pushed mine without artifacting at

700/780 but i dont dare go further....unless i want my card to die within 4-5 months


Im not criticising ...just warning that it may be dangerous.

 

Just a warning, you do know that there are no temperature sensors for the memory itself. I've heard of several cases where people's GPU's burned out because the memory fried even though the core temperatures were good (they had ~900 MHz on a 600 MHz stock).

 

185.20 is bareable for me, I have no brightness control but they make gaming hella smooth

And I cant understand how your laptop's GPU mem can take 1.1GHz

 

i give your GPU a month at those clocks to die... it is a dell, and it is a 8400... nuff said

 

sigh....i guess overclocking just cant be taken seriously anymore

 

Bah, installed dox 185.20, yet again lost resolutions and the ability to make custum resolutions. And testing games, oblivion dropped 3 fps, crysis was about the same (-.3), and 3dmark dropped 50 points. Because of the resolution issue yet again I went back to 179.28. I'm only installing official updates in the future..

 

Yes it can, those people that over-overclock will just learn the hard way.

 

I think that overclocking for laptops is underrated cuz people thought i couldnt push my card as far as 600/730 on some other desktop forums.

but i made it and im still running strong after 7 months on this clock

 

Nothing wrong with overclocking if it isn't causing crashes or artifacts and it's a reasonable temp for your laptop. It helps to have a good cooler to keep temps low, but there are limits to your GPU.

 

ive been running my gpu at these clocks for quite a while now around 3 months and its been fine. Plus when im using my laptop in power saver mode (which is most of the time the gpu downclocks itself to 169mhz core and 100mhz mem.)

And as for the GPU memory overclock is it that of an overkill to go that high? i mean i know its a 64-bit bus and overclocking it to death wont yield performance, but i dont want my baby to die D:

 

There's a huge difference between a 730 (+130 MHz or ~20%) and a 975 (+375 MHz or ~60%) overclock on the memory especially since you can't detect temperatures. Overclocking the core is safer IMO because you can see how hot the core is getting.

IMO that memory OC is huge and as I said before, several 8400m GS/T users have reported fried video cards with clocks over 900 MHz on the memory. However, you may have a lucky GPU that can handle that speed, who knows?

 

oh yeah i shouldve added that i live in norway and its around -10c outside and the ambient temp where i keep my lappy is around -1 to 0 ish atm.

btw overclocking the shader clock does it have sideeffects?

 

lowered my mem clock to 900.

 

That explains a lot I'd love to OC with an ambient room temp of that

 

but penguin do you know if a 8400m gs's is unlockable to a 8400m gt?
cause they both have g86's.

 

I dont know. Try Google?

 

Difference between the 2 models is twice the number of shader units for the GT, this cannot be changed through software means. Read the graphics sticky by Chaz and pay attention to his note on the 8400GT.

 

If you could get a really good cooler for your laptop in addition to that really cold ambient temperature would really help your GPU.

think Zalman NC series for really great cooling.



and btw even 900mhz is an overkill for your card. You can expect to keep your card safe within 5 months before it fries.


like the other poster said i think that Core OC'ing is much safer because atleast you can watch the temperatures

 

Making large jumps in temperature is exactly what decreases the lifetime of defective g84 gpu's. Maybe you are doing the right thing: better blow it up before warranty expires
