Stock 8600GT GDDR2 vs Stock 8600GT GDDR3

Sorry if you clicked this thinking you would get a comparison lol. I would like to see some kind of comparison between them, some people have received their inspirons and vostros and theres bound to be other people with a GDDR3 8600GT in some other laptop, there should be a stock comparison done, no overclocking or screwing with it, just a stock comparison. With clocks listed as they will differ. Its obvious the 8600GT GDDR3 will win but the thing is, by how much?

 

in what benchmark? (say 3dmark 06 and i will slap you)

i recommend either the half life 2 lost coast video stress test or the counter strike source video stress test.

i am quite partial to both of those. the engine is very refined for use on the pc. newer games will have big sweeping performance differences with new drivers and patches.

you understand.

 

hahah... yea look for real game testing with fps if you are looking. IMO, even tho im not a EXpert, the difference won't be MAJOR, unless the game really needs ALL of that dedicated RAM anyway...

 

300 MHz

 

actually this doesn't have anything to do with the amount of ram.

this is a ram speed test, which is pretty important. these cards have fast cores and are bandwidth hungry. i can actually do the test myself assuming i can get a driver i can set the clocks on...

its just 400mhz memory vs 700mhz, and thats the only difference. the core and shaders are clocked up to nvidia spec right?

 

Any 2004 or later FPS/RTS. All the ones ive seen so far have been with overclocking a bit usually so i don't know much much a stock GDDR2 will lag behind a stock GDDR3 card in games.

 

Sometimes if the processor is different, the ingame performance is different, so make sure everything is exact except the GDDR2 GDDR3 thing

 

Masterchef- I believe you can use hacked drivers and a registry edit to bring up the classic control panel, which contains overclocking built in. This should also allow you to see what the default clocks are the for your chip- I hear the MBP's are underclocked, as are the Sagers. I'm not sure if they are underclocked to the same level, however.

Default clocks (off nVidia's Website) are 475/700. http://www.nvidia.com/object/geforce_8600M.html

Rumored clocks for GDDR2 version are 475/400, although these are unconfirmed rumors/hotly contested OEM specifications.

 

PLEASE explain how to do the registry editing to unlock the ability to set custom clocks.

i am using windows xp.

just link me or anything!

thanks.

currently i have tried ntune, atitool, and riva tuner, and none of them will allow me to set custom clocks. i click on the "set" button in each app and it yet the clocks stubbornly sit at 470 / 635...

 

This thread outlines some people who are having the same problem as you. Unfortunately, it seems like using the 158 drivers are the only way to overclock. As for the classic control panel, it seems like they disabled the overclocking functionality in the newer drivers anyway. Sorry about the misinformation.

 

I was really mad when I saw my both my experience Index was lower and same for my 3dMark Score compared to the Asus G1S( GDDR3 8600gt).
GDDR2(Inspiron 1520):
Default:
Core Clock: 475 MHz
Shader Clock: 900 MHz
Memory clock: 400 MHz
Benchmark 3dmark: 2839 ( I don't remember it might have been lower but not higher it was in the 2k range did the benchmark long time ago)
Experience Index Windows: 4.6
Today I downloaded these drivers:

I overclocked it with RivaTuner my stable results were:
Core Clock: 611 MHz
Shader clock:1425 MHz
Memory Clock: 495 MHz
Benchmark 3dmark: 4097
Experience Index Windows: 5.9
Temp: Idle: 46 C Load: 56 C ( the load temperature is from 12 hours worth of gaming)
The GDDR2 has amazing overclocking capabilities but the Memory clock is max of what it can go or it wont be stable. I can bare having 205 MHz lower than my friends memory clock. His is already overheating with a core clock of 475 mhz. Anyways you wont beat it in 3dmark benchmarking cuz of the memory clock GDDR3 has but you can get close to it. Ill tell you the testing of the Asus G1S as soon as my friend comes back from uni.

All I know is from my experience using the Asus, it gets so hot its not even playable because of heat starts to irritate your hands. On my Dell I dont even feel the temp difference.

Anyways sorry for my horrible english its not my first language. But Ide thought I share my overclocking experience because im sure alot of 1520 users were disappointed in their benchmarks, this will change lotsa stuff now I hope

 

NOTE: I just wanted to let you know these are numbers VERY STABLE you can overclock it even more if you like to but you will start to get blue screens and random crashes, I wouldnt suggest higher values than these for the GDDR2 version. I have played constant 12 hours stress test without any crashes or blue screens.

 

A Big Very Noticable Difference--worth Extra Money!!!

 

I thought default clocks for 8600m DDR2 were 475 Core / 400 Memory? not 400/400.

 

oh I apologize that was a typo fixed it.
