I just received a Forsa GT 640 4G 2GB DDR3 graphics card. Trouble is I'm worried about its genuinity. The item looks a lot different than what was displayed on the seller's site (I've put up a complaint there but want to confirm there too).

I'm doing my first build and literally don't know anything much about graphics cards. the card doesn't seem to have been tampered with. But the no. of fans is different - 2 in a copper case kinda structure while seller's pic showed a shredder like single fan. Ok, sounds off-topic but no warranty details came with it. Installation CD's there fine.

Ans I guess the slots too look different.

I'm adding pictures of the actual product, can somebdy identify it, of course I shall be trying and checking it by placing on someone else's system as I'll get the other stuff for the build a little late into November. I need quick answers please coz of the limited replacement period of 10 days.Photo-0162.jpg Photo-0161.jpg Photo-0163.jpg

It may be a different revision so it could be genuine. Only way to find out is to install it and run a program like Speccy for the data. Make note of the revision no.

To add to what Brazened has advised, check the images at This link and you will see two versions of the card.

Well Folks.
There web site is well hidden, seems it has only been up since 2012, and a bit sparse, > http://www.forsa.com...10#.Um0je3BRai4 And that looks like the latest release. Any other of the 640 are like this,
> http://www.bidorbuy....lk_128Bits.html Many advertised a 4GB Memory but looking at the specs, they are all 2GG. I don't think they make a 4GB

Yep and this from the bottom of their home page;

Thanks Brazened, Phillpower2 and Iammykyl.

That image from the forsa.hk website matches the thing. I've sent it for being checked by technicians working with my Dad at the office. Fact is there's a bill, where somebody's sort of made a revision( I mean cut of 2 GB with a pencil and written 4 GB ) and the fact that the person doesn't seem to be wanting to hide the correction bewilders me ( making me think that they really aren't trying to cheat me ). Again the 1 year's manufacturer warranty is missing.

One more thing, the Installation CD, after getting done with the driver installation, i get to see all the specs?

I'm worried about checking on model, memory, CUDA cores and yeah that it's perfectly fine, not defective in any way.

Once again thanks to all three of you. And if you see this reply in an hour or so then please give me a quick answer if you can, I would need to inform he supplier for a replacement.

And could you pleas also tell me what's with the 4GB version actually being 2 GB?

Thanks in advance.

And oh I felt I needed to make this addition, while I was haring around this web after posting here I too found a 4 GB model but looked same as mine, not this red single fan model.

Then there's this seller advertising this confusing ad:

Ok and another:

Hello ArionIV

I couldn`t find the Forsa brand anywhere in Europe or the US etc but I did find well known brands that make a 4GB version of the GT640, Examples

You are welcome BTW :thumbsup:

Hi phil,

I checked myself and the graphics card is available for a little bit higher. Is my first build and the main thing I'm looking forward to is something robust, and meeting my requirements for MATLAB programming (financial applications). What would be a good bet in the long run, the 2 GB model or the 4 GB, because I would like to keep this system I'm building running for at least 5 years, so that no major technology changes make it look redundant too soon.

I see from the specs that the 4 GB model has a marginal advantage over the 2 GB, i mean specs other than memory of course.So is it worth it, paying the rest of the premium(i mean the margin, in case i sounded wrong or confusing)? Because I'm so pissed with these retailers I'll go for the only good retailer maybe lose out on discounts but get the products there.

Please give me an opinion.

Gday.
For your needs, 2GB of memory is all you need and will do you for the foreseeable future, (will support 3 monitors) unless Metlab drasticle changes system requirements.
Part of the system requirements.
" Graphics Processing Unit (GPU) for displayMost MATLAB graphics are rendered on the CPU, not the GPU, so you can use any recent graphics card with MATLAB.The performance improvement on a high-end graphics card is relatively modest when compared to an entry-level graphics card. However, MATLAB is increasingly using the GPU's rendering capabilities, so choosing a high-end graphics card is a good way to prepare your system for expected performance boosts in future versions of MATLAB.Graphics Processing Unit (GPU) for computationTo speed up computation, Parallel Computing Toolbox leverages NVIDIA GPUs that support CUDA 1.3 or later. See the full list of supported GPUs. MATLAB does not support computation acceleration using AMD/ATI GPUs at this time."

So at the moment Metlab would run well on a card with 1GB of memory. When you have been using the software for a while, you might, in the future, look at a RAID setup and more memory.

According to the website, Forsa don't manufacture any cards with 4GB of RAM so claims of 4GB I consider false advertising. > http://www.forsa.com...10#.Um0je3BRai4

What's a RAID setup? I have heard the name earlier but then its only now that I'm taking an interest in computers and programming.

You would consider me even more lousy if I tell you we had a PC Magazine subscripion until a year back or so and wait if I rummage through the pile, I may get their RAID system build issue, but I never understood a thing.

Gday.
RAID is using 2 or more drives to write to and read from instead of just using one drive. It is something you might look at in the future, but you need to have a full understanding of your software first, some info to start you off,
