What clock speed is your 8600m GT?

Just out of intrest, those using 1520, and similar lappys now have you upped the gpu clock at all?
How much by if u have?

 

I have the 8600M GT (apparently) and I had it up to 650/700 cpu, memory and it ran fine like that.

 

I could get mine up to 630.... but run it at 580 for safety. I run the memory at 445 because it becomes unstable above 450

 

Max I ran stable was 605 GPU / 510 Memory.

I bumped down to 600 GPU / 500 Memory to ensure stability.

 

What happens when it gets unstable?

on Nvidia's website, it is listed as 475/700

 

wow.. my 8600m gt is on 630/525 and is running stabily.. when my cooler arrives in the next week or so, im going to try push it to 650/540 maybe.. but ive been above that with driver errors so i dont think its gunna happen.

 

Usually, the gpu driver will crash, preventing further overclocking until reboot

for me, the worse ive gotten is the card crashing so hard that my lcd looked like a television with no reception, it was weird and i thought i killed it , that was dangerous clock tho 635/580

i stay at 620/569 now, no crashes or instability

ps: gddr2

 

hmm not bad.. gunna try get memory clock to 550 today.

 

i run 550 and 880, well within the bounds of safety. i should probably try pushing it further and clean out my fans and go outside where its cold...

 

I run 625/525 stably, get around 25 FPS in crysis med and some high settings. I really like how well this system handles OCing.

 

do you have a 1280x1024 3dmark06 score with that? if you do what os?

 

clicked at the wrong time and got the clock of 655 Of course it crashed!!
XDD It was a mess trying to get the cloaks back.
Max would be 650 for me but i would say 645 since 650 already shows altifacts, but i clock for 550 for stablitity since i don't have any demending games to play. Also i am used to lags so i don;t really care about ocing much because of ati 200m that i used to have

 

I run 600/500. I've never tried past 615/515 just because I feel safe with 6/5 and I'm happy with the results. Running pretty cool with the notebook cooler now.

 

I just upped it to 550/450 from the default 475/400 and it's running great - less glitches than at stock frequency for some reason. It helped a bit in my only racing game (already at max but a bit low FPS), but other than that I was already at more than enough FPS at maximum settings, so I have no need for further overclocking.

Been a couple years since I got any games...in a few weeks that might change, though. Nice to not have to turn any settings down even with stock clock though.

Also should note that 475/400 is the default for the DDR2 version, apparently 475/700 is for the GDDR3 version. Makes quite a difference as to how high you can get the memory clock.

 

My 8600M GT GDDR3 has standard 475/700 and I OCed to 560/780 now.
And It's stable...
My only problem is the temperature (so in a week i will have a notebook cooler )

 

for me , my 8600M GT DDR2 can be overclocked to 650/540 through Riva tuner , anything a little bit above shows artifacts , i am stable on 650/540 @ 65-70 celcius , Dell Inspiron 1520

 

GPU is 475MHz which overclocks nicely in most cases to around 600MHz.

The DDR2 is 400MHz (800MHz effective) and the GDDR3 version is 700MHz (1400MHz effective).

When it gets unstable it basically either dumps to desktop, causes artifacting, or just crashes the PC.

I had mine running 620/515 for a couple hours, then had a couple instances of a crash after some heavy benchmarking, so bumped it down. I could probably run it at that and chances of a crash are probably slim to none since my GPU probably won't be taxed as much as the benchmarks did. But I won't gain much in performance between 600 and 620 or 500 and 515 (3DMark06 score difference was less than 100) so rather be safe than sorry.

 

569 Memory? You are one lucky bastard. Most DDR2 won't go past 520 or so without excessive cooling.

 

Yeah, and its weird, i'll use that memory clock for playing a game for hours

maybe its cause it less than 70f where im at right now, but ive had no problems with this clock, but taking it up like 5 mhz crashes everything in about 15 minutes

also could be form factor or the fact that my fan blows out enough hot air to heat a small room

 

guys wtf my memory shader wont go above 450 without crashing... and the temp never goes over 50C... so what the hell can i do to get it over 450

 

Do you mean GPU memory which is stock clocked at 400MHz? Your shader clock should be 2x your GPU clock.

You may have just got the bad luck of the draw and 450MHz is its maximum potential. Temperature doesn't have anything to do with it. That's the thing, O/C'ing is pushing the hardware you have above its normal operating limits, so you're guaranteed nothing.

However, 50C is quite cool. Is that idle and how are you measuring it?
