Is there any interest in doubling GPU memory capacity on RTX portable workstation ?


Recommended Posts

Hi, 

I wanna know if any of you guys could be interested paying a service to upgrade/replace the GPU memory of your workstation/laptop so you could double the capacity ? For now I'm offering such upgrade (on local France forum) for like 150€ the 6GB to 12GB upgrade (192bits bus width) and 200€ for the 8GB to 16GB upgrade (256bits bus width).

It's mostly aimed at lower SKU like Quadro RTX 3000/4000 (low/mid tier series) cause Quadro RTX 5000 (high end series) is already at his max capacity, it applies to Turing and Ampere generation (Ada is already using high density memory IC). It also apply to gaming cards but it's a lot harder to find the memory strap resistor/boardview.

I don't know if there is any needs to double the memory capacity on portable workstation, 6/8GB should already be plenty for many uses cases but I don't know I upgraded the RTX3000 of my Precision 7730 to 12GB anyway 😄

So what's your thoughts ?

Desktop / I7 12700K @5/4GHz 1.24v / MSI Z690 Edge Wifi DDR4 / 32GB DDR4 B-die @4000c15 / RTX 3080 EVGA XC3 Ultra / Triple 27" 4k120 + 2*4k60

XPS 9500 / I7 10750H @3.2GHz all-core / 32GB DDR4 2400MHz / GTX 1650Ti 4GB (upgrade to 8GB planned) @50W / 15.6" UHD / NVME / 86Wh

XPS 9570 / I7 8750H @3.2GHz all-core / 32GB DDR4 2666MHz / GTX 1050 Ti 4GB @50W / 15.6" UHD touch / NVME / 97Wh
Precision 7550 / I9 10885H @4.6GHz all-core / 32GB DDR4 2933MHz / Quadro RTX3000 6GB (upgrade to 12GB planned@80W / 15.6" FHD IPS 500nits / NVME / 95Wh

Precision 7730 / I7 8850H @4.4GHz all-core / 64GB DDR4 2133MHz / Quadro RTX3000 12GB @80W / 17.3" FHD IPS 60Hz / NVME / 97Wh

 

I was the one that run an overclocked I7 3920XM @4.2GHz all-core in a M6700 with 32GB 2133MHz DDR3L, a Quadro P4000 and a 4k eDP display (also did dual LVDS/eDP internal display)

I've been curious about having this done to my older cards liek the 5970, 690, gtx 295 and such but I dont have a hot air station nor have any skill in such things lol

 

I can solder more or less but no experience with hot air yet


With heating plate and hot air everything is possible 😄 It would be cool to replace mobile core with desktop one, like one guy did on NBR with 980.
In China lately a lot of older GPU gets more memory upgrade, sometimes even up to 24GB I heard.

Don't know about older, newer GPU needs correct strap resistors to set up memory vendor and capacity. Also force eDP output (and use mining GPUs with laptop).

 

With steady hand and BGA soldering skill, every BGA CPU is socketed. ^_^ Beginning is harsh, with every try it get easier.

With that premise the one thing I really wanted was the Alienware 13 R3 with 7820hx instead of the 7700hq, heck maybe a 8850h and disable the dGPU for eGPU but nothing like that existed or exists. Would've been really cool to see.

 

Older GPU may be similar, that was the main issue @Khenglish ran into with installing desktop GPU vRAM modules to MXM board on the same mod you are referring to IIRC.

 

Love seeing these kinds of mods though!
