9600 GT - DDR2 or DDR3?

hi guys.
i have an acer 6935G and the memory installed is 4GB with DDR3 aswell as GPU which says DDR3.but since i've been browsing the forums for quite some time,i've seen people stating that acer doesn't really support DDR3 on this machines and it acts like DDR2.How can i change it to run as DDR3 than? And how am i sure it runs as DDR2 or 3?
Please help.

 

GT = GDDR3 GS = GDDR2 , I think

 

no,i've read there are also GT's with DDR2

 

I don't think so- 9600GT was mainly DDR3 but there were some with DDR2, but I see no connection between mentioned RAM of 4GB and GPU memory.
What's more I think this notebook uses DDR2 system memory modules.

EDIT: My bad- I see that system memory is DDR3. As for the GPU you can check it with GPU-Z but it was mainly 512MB with DDR3 but 1GB with DDR2

 

yeah - every program tells me it's working on DDR3.
then how come people are saying it's not working to it's full potential on DDR3?

 

I don't know exactly what they mean- it's clocked at 800MHz. That is normal.
3D Mark score for DDR2 version is around 4200 (1280x768 in Acer 6935G) while DDR3 verson of Aspire 6930/6935 score about 5700.
I'd say there is enough difference.

 

That would be because they're wrong and/or misinformed. The Internet is pretty good at providing a lot of useful information, but better at providing wrong information. DDR2 and DDR3 are hardware incompatible; if you've got DDR3 memory, then it's working as it's supposed to.

What people may be referring to is the performance difference between DDR2 and DDR3. As was the case of DDR vs DDR2, there's a certain tipping point where DDR3 overtakes DDR2 in performance. Before that, the two are on par with each other. Unlike with DDR to DDR2, DDR3 is not any "slower" than DDR2. The higher timings usually specified by DDR3 DIMMs is due to the lower clock cycles by which they're measured; the actual elapsed time (10ns) is about the same as DDR2.

All this is not to be confused with GDDR3, which is a completely different technology used by video cards for VRAM and is what your 9600M GT is using.

 

i understand.thanks !

 

And that's why I couldn't see any connection between system RAM and GPU.
Good job Zoomastigophora- although I'm not sure if you should be glad you understand the "misinformed"

 

Thanks, and everyone has to start learning from somewhere. It's just that thanks to the Internet, they usually start off learning the wrong information.

 

Why not use GPU-Z to check it out..

Every available info from the GPU will be displayed by GPU-z

 

gpu-z says GDDR3

 

I think it's settled at this point. The question was actually about DDR3 system RAM and had nothing to do with GPU RAM.
As for GPU- if GPU-Z says GDDR3 it's GDDR3. This app had no problems differentiating GDDR3 from GDDR2.

 

Hi Vlad6,

I've encountered similar problem as yours, but the difference is mine happens to be 1G DDR2 when the brochure stating it as 1GB DDR3. WhenI started questioning why the machine performance not as it supposed to be on gaming,so I use the GPU-Z to check and it's appeared as DDR2. So obviously, I made a complain to the reseller and they redirected me to the acer service centre, so after i reached there and served by a very lousy technician (Acer has a very bad customer service, it has becoming a common sense) which doesnt know a things and replied me by "The hardware itself supposed to be ddr3 it's only showing as ddr2, there's nothing much we can do about it", He wanted me to be satisfy with that kind of half- answer??. so i asked them to prove it, after a long series of testing (Gpu switch, Manufacturer number chek) and they gave up and redirected me to the manager, andddd... here's another joke of the year from the manager "The firmware is not ready for the GPU, it's currently being developed, we will notify you when it's out". I mean... C'mon, it's been a year after it's released. So in the end I asked them to replace my So called 1GB ddr3 with 512MB ddr3 and voila i got 25% performance boost and it's appears I'm not the only one that has this kind of problem many people does, but the things is poor them who are not tech savy to notice the different and becoming the victim of Acer scam.

 

Wrong.
My housemate was using Geforce 9600M GT 512MB DDR2.
Both GS and GT have DDR2 and GDDR3 versions.
