1520's 8600gt cannot be overclocked? (and a few other tidbits)

Yeah, so I just got my 1520 today and I was hoping I could overclock this baby to compensate for the lower memory clock and to my suprise, I can't.

I tried ntune/rivatuner/atitool, everytime I move the slider over the standard clocks it moves back to it... Don't tell me I gotta bios flash this baby just to overclock it .

Oh and its wierd since all the drivers are still new riva tuner is detecting it as normal DDR3 NOT GDDR3, and Ati tool is detecting it as SDR? Anybody know what's up? I wonder if Dell really did put gddr3 ram in there but just underclocked it to 400mhz instead of the normal 700.

Anyways tell me if anybody has luck overclocking it cuz i have a feeling that eve if its ddr2 its going to be one hell of an overclocker judging by the fact the temp doesn't go over 60*c when used on the artifact scanner on atitool.

Chaos

 

Here we go again....

 

There's a thread entitled "Sweet..." here that's about a billion pages long which basically concludes that the memory on the 8600M-GT is indeed DDR2.

I'd love to hear if anyone can overclock it... anyone have any success yet?

And congrats on your new lappy!

 

I'm hoping that it can be overclocked pretty well, especially since people are saying that the laptop handles heat so efficiently.

 

OVERCLOCKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKK




though i personally find 60+ C pretty hot

what temps are these gpus rated for?

 

I used Rivatuner to go up to 503/425 just to see if it would hold and it has through a restart. I'm running Ntune's stability test right now.

 

I can overclock in Vista, but not in XP. Kind've strange.

 

Oss, what clocks have you used? I'm worried about pushing too far.

 

the desktop version of 8600GT are pretty good overclockers, and since they both use the same core i'm going to assume the same for the 8600M GT.

 

I've only been playing with the memory speed for a bit, because that's where the biggest improvements will come from. I've only clocked it up to 470 atm. Will try more after I get XP to allow overclocking.

 

i know this is posted all over but i'm too lazy to find it...i read it somewhere but i forget what it is...what are the default clock speed values for the 8600M GT?

 

475/400 for Dell's 8600m GT.

 

thank you!
