GPU memory chipset

[Mohammed]

Hi tpu-m

I have a GTX 960 with broken memory, GPU still works but with crazy artifacts. so i am trying to get a replacement memory, anyone knows where can i buy them?​

​

my second question is, Is it possible to upgrade gpu memory, that GPU still has 2 free room on PCB, so do you think if i soldering 2 more chips will upgrade memory ? anyone done it before?!






thanks in adv

It's dead, don't bother.

Only way is to contact the manufacturer, also the ram chips are bga mounted typically. So unless if you have a machine to print a pcb and fuse the ram chips to the board you might aswell downclock the ram or increase voltage.

Other choice is attempt an ovenbake...

 

[Mohammed]

what about hot air gun? do you think it's enough to do the job?

 

[IceScreamer]

As @eidairaman1 already said all you can do is bake it in an oven (just the PCB), and even then it's only temporary.

 

[Mussels]

warranty
oven baking
bin

only three options you can try

 

[Mohammed]

out of warranty, as well EVGA not cover any broken parts
the problem is one of chips are broken, it have a large scratch on the top

BTW, I've found some chips on Ebay but still not quite as same as mine. model are same but some number are different

GPU has 504 but this 501

You need a decent IR station for that sort of work (several hundred USD). Hot air gun will not work, to uneven.

As Mussels said, baking it and binning it are your only options.

Keep in mind that any penny you still spend on this dying product will be a penny wasted that cannot go towards a new GPU with some actual performance in it.

A 960 isn't really something worth saving IMO, probably even better off replacing it with a second hand card from someplace, perhaps you can snag a 970 somewhere for cheap, big boost.

Tangential, but I just had a look at a popular auction site here and man the GPU prices has gone up. A GTX960 currently sits at €100 and GTX970s go for €150.

Mining demand has probably driven the gamers to go searching in last gen. It's pushed prices up.

Well, 150 for a GTX 970 isn't a ridiculous increase. A couple of months ago I could (and did) sell a slightly faster 780ti for 180 EUR and I bought it a year earlier for 220 or so (2nd hand as well). I'd say its a much better deal than a new Pascal or RX580 right now.

If you want BAD deals; check this out. People are definitely going mental

uh sound like more works
i have a bad history with baking. I think TV repair shop can do the job.

 

[Mohammed]

but the real question is, do you think memory chips will not conflict with GPU,

 

[biffzinker]

Double posting is frowned upon. Condense your posts.

 

[Toothless]

As other people have said; bake or bin. Your little TV repair shop doesn't the have tools to fix it.

 

[Mussels]

baking it is simpler than resoldering a RAM chip... your priorities seem backwards here

They might actually (not likely though), but unless they do it for very little it'll not be worth it.

You used to be able to get one for €100. Ans they are pretty old at this point.

EDIT: Not to mention Polaris. Computer components really shouldn't increase in value, but in the past few years it's happened several times: DDR3, SSDs >200GB and GPUs.

 

[eidairaman1]

Best advice, bin the card and buy a 780ti with more ram.

I seriously doubt the ram chips are compatible.

Don't waste any more time, or waste money.

They are called pcbs for a reason, thus are field replaceable units.

I doubt the local tv repair shop have the facilities to repair pcbs.

 

[Vya Domus]

Any repair shop will charge a fortune for such a thing , if this is even feasible.

 

[Static~Charge]

I think TV repair shop can do the job.

Like eidairaman1 said, your video card's RAM chips are BGA (Ball Grid Array):

In a BGA the pins are replaced by pads on the bottom of the package, each initially with a tiny solder ball stuck to it. These solder spheres can be placed manually or by automated equipment, and are held in place with a tacky flux. The device is placed on a PCB with copper pads in a pattern that matches the solder balls. The assembly is then heated, either in a reflow oven or by an infrared heater, melting the balls. Surface tension causes the molten solder to hold the package in alignment with the circuit board, at the correct separation distance, while the solder cools and solidifies, forming soldered connections between the device and the PCB.

I wouldn't bet on your local TV repair shop having the necessary equipment for this type of work.

It is possible and doable, but in your case - not cost effective, because you have no skills or proper tools.
Also, GDDR5(especially Samsung) is expensive if you are buying small quantities.

VRAM can be purchased on Aliexpress. You will also need some soldering equipment which can do lead-free BGA components (it's pain in the ass to do larger cards with hot air rework station).
Also there is no guarantee that these chips are authentic and are within spec for this card. My last batch of GDDR5 I bought was 50/50 percent defective.

So, the conclusion is: it's not a home project and you can't do it without tools and skills. Basically you are better off getting a new card.

 

[ArdWar]

The general advice about BGA soldering/rework is that if you never done/practice it before, then don't bother trying (excluding if you doing this for the experience)

Same advice also apply for other fine-pitched chip package

Even more reason against it if they use lead-free solder. You just don't bother to rework them
