upgrading DDR3 to GDDR5

if one bought a ATI5470 with DDR3, can he later upgrade to GDDR5, or am i talking nonsense.

 

Memory associated with the Graphics Card cannot be upgraded. System memory can be upgraded, but that is not tied to the graphics card, except as extra memory in case the memory on the graphics card (known as the frame buffer) runs out of space.

 

If the notebook has removable graphics, then you could swap the entire GPU.

But you can't just swap vRAM.

 

thanks guys.
then speaking of ATI 5470 with GDDR5 is pure waste of time. but I sure hope the card reviewed and tested on the different websites used the DDR3 not the GDDR5 (they never specify), b/c that means i'll get a lot worse performance. Is that right? is there a GDDR5 ATI5470? Can I post the link to the review I'm talkin about. It's from a similar named site ;P.

 

The 5470 appears to be available with either DDR3 or GDDR5, and yes, the performance difference will be significant. However, the card isn't meant for gaming, except for pre-2006 games, or some modern games on low settings. For the purposes you would use this card for, GDDR5 shouldn't be all that important. It would be like something along the lines of supercharging an '87 Yugo.

 

There is no such notebook card. GDDR5 is limited to the high end cards now, though it is planned on hitting mainstream and budget cards shortly.

 

Notebookcheck says it is available in GDDR5 flavor, but I didn't check to see if any notebooks actually use that.

 

Notebookcheck says a lot of things... there is a chance I'm wrong, but I've never seen a notebook with one.

 

ATI says it has a GDDR5/GDDR3 interface: ATI Mobility Radeon? HD 5470 GPU Specifications. So it's entirely possible. It's sad that my 5830 doesn't have that option

 

All that really needs to be said.

When NotebookCheck says a card "supports" GDDR5, that usually means that the desktop chip which it's derived from uses it, therefore the mobile GPU "can" use it, but that shouldn't be read as meaning that we'll ever see one.

If you have a link, to a machine which has a Mobility 5470 GDDR5, please do post it.

 

Yeah, on Notebookcheck is says my 4870 X2 is DDR5 yet no DDR5 variant was ever made.

I even emailed them and told them...they told me I was wrong...

 

hi guys.....m a newbee.........can someone kindly explain me that what does this statement means as written by Notebook / Laptop Reviews and News - Notebookcheck.net

To compensate this, the GTS 350M supports GDDR5. Therefore, the performance is significantly lower when cheap DDR3 memory is used.the card is a fast middle class card (with DDR3 graphics RAM) or even a slow high end card with GDDR5.

guys m confused that according to my info GTS 350M comes with ddr3............then why they say that with gddr5 becomes slow high end card????it has a version with gddr5 also??????

 

They're saying that gDDR5 compensates for the 128bit memory bus. Basically 128bit gDDR5 = 256bit DDR3 clock for clock.

 

What it's saying is:

There may be two versions, one with DDR3, another havng GDDR5; when the card is equipped w/ GDDR5, it climbs into the high-end tier of mobile chips.

 

you can try desolder the DDR3 chip , and solder the GDDR5 chip onto it . *nonsense*

 

JohnnyFlash, Kevin_Jack2.0 and devilcm3 thanx for ur assistance
i went onto nvidia site...they din mention that this card is ddr3 or gddr5
(ormay b m unable to understand the technical terms)..........n also there is no indication that it has two versions or not.........any body with any clue or refrence that it has two or may b three versions????
when this card is having DDR3 SDRAM(i got this refrence from http://www.bhphotovideo.com/c/product/700338-REG/Toshiba_PSAW3U_042001_Satellite_A665_3DV_15_6_Notebook.html#specifications) where they specified it,then why Notebook / Laptop Reviews and News - Notebookcheck.net guys saying that when gddr5 used,then it becomes slow high end card........?????how can it support or perform better with gddr5 when it has gddr3?????

 

if only it was possible i'd have a gddr5 4870 by now

 

Just because Nvidia publishes the specs for a GPU, it doesn't mean that the manufacturer (ASUS, Dell, etc) has to use those specs. Just look at Sony and their underclocked/undervolted GPUs. Plus, there are plenty of GPUs on paper (and notebookcheck) that never went into production, like the GTS 260M, 5750, or 5770. With the 350M, it is likely 'compatible' with GDDR5, but I doubt that any manufacturer would spend the extra money to use GDDR5 instead of the cheaper GDDR3. If they were going to do that, they would just use a 360M instead. There's no way they'd put GDDR5 on a 5470, that'd just be wasted, the GPU is just too slow.

 

ya dude , i guess right exlpanation.............dont think that 350M wud come with gddr5...........

 

Well it is possible. Just depends if you have the equipment and the skills. Someone just posted that a company took a normal GTX 480M and added an addition 1.5GB of ram to it and replaced the GTX 480M core with a GF100 core on it.

 

yup but you have to have the capacities of a compagnie wich is considered as impossible by the end user
