Insider Claims NVIDIA GeForce RTX 50 Series Transitioning to Usage of SK hynix GDDR7 Memory Modules
So far, NVIDIA's GeForce RTX 50xx graphics card models have shipped with Samsung GDDR7 memory modules onboard. According to a fresh MEGAsizeGPU (aka @Zed__Wang) claim, a change in vendor has already occurred. The tenured tracker of Team Green inside track information believes that the company has: "started to use SK hynix GDDR7 for the GeForce RTX 50 series graphics cards. Started with GeForce RTX 5070 first." Officially, NVIDIA's latest board designs can support GDDR7 modules produced by the "big three:" Samsung, SK hynix and Micron (see BIOS info below). Team Green's comfortable market leading position probably grants plenty of negotiation power to pick and choose the best component deals. Day one evaluators performed teardowns on GeForce RTX 50 series review samples; TechPowerUp's W1zzard found Samsung "K4VAF325ZC-SC32" GDDR7 units—rated for 32 Gbps—onboard various GeForce RTX 5080 16 GB models. As outlined by VideoCardz, the rest of NVIDIA's "Blackwell" gaming product stack sticks with 28 Gbps-rated Samsung GDDR7 modules, extending to its Mobile portfolio.

nGreedia usually does this after a launch, they get them at a better price (for them), but their quality is lacking, they can never clock as high or last as long.
I'm not opposed to component changes after the launch per se, as long as the mfgr is upfront & forthcoming about it (leaving ME with the choice of either buying the item or something else), which again, nGreediya never does & will never do, for the same reasons stated above..
Wonder how much (if at all) memory has been the limiting factor for 50 series availability.
If these achieve the same clocks, long term, I don't see an issue out of it, as the products will be identical. If they're worse somehow, then it's problematic.
Samsung probably has yield issues too, so it's better for Nvidia to source GDDR7 from different vendors to increase Blackwell production rate.
I think about m2- SSD- NVME and Storage where component swaps are worse.
-- I do not agree with ngreedia as sourcing components is a very important task in electronics. I assume the lowest price will be the most likely the most important factor. I comment quite often about poor build quality or poor material quality.
Note: Do not buy AMD graphic cards - they are the "RED DEVIL" and evil and bad and fancy and ... ... you know the rest.
And yeah, their brand name for me is nGreedia, branded them like this, mmm, ages ago anyways, doesn't matter, it's been 5 years or more, I even said, that is what I will call them from then on (you can search for the post if you wish)
They showed 40Gbps speeds a while back. Also 3GB modules. Laptops may use the 3GB modules but i doubt we'll see 40Gbps before the mandatory Super refresh.
Here is the thing, nGreedia might not have promoted it as such, but their "influencers" sure as hell did, you know the ones, probably, not gonna mention "names" :p
Btw if you can afford a 5070Ti, I bet you are also greedy, as in earning more than minimum wages to survive eh, and i'm also greedy too :toast:.
If Nvidia were a little less greedy, they would be a monopoly already
- My GTX1650 was only an interim card for my previously crippled 8GB VRAM 3070Ti, if it had 16GB VRAM, I would have kept it. I had planned on getting a new GPU 6 months prior to the 5000 series launch, I saved a little more, as I had crypto/covid vibes, as BTC was mooning.
- I knew South-Africa will be heavily sanctioned because of their treatment of the white minority, our Rand was already in the ****ter and was going to get worse, which it did and is still getting worse day by day. I dodged that bullet, this isn't even with the AIB's and nGreedias shenanigans, that is just extra icing on the cake.
- The markets were going to go apeshit with all the tariffs, which I knew would happen, it was inevitable.
I skipped all that noise by being quick, I got my GPU at MSRP though, or I wouldn't have bought it, so there is that, unfortunately I still had to pay the ASUS tax, but w/e. I originally wanted a Zotac, but they decided to go ape**** 1 hour after the launch and pumped those prices right-up and retailers happily adjusted. I knew about a computer store I used as a child and never grew as big as most and they had 1x ASUS card, which I snagged. They didn't have a 5080 which I wanted, but alas, probably for the best, as I knew I would be CPU limited with the 5070Ti, but I am waiting for the 10800X3D before upgrading that part of my system, then there is the fact that the 5080 draws near 400W on these ridiculous 16-pin, which at present, is not such a good idea, my 5070Ti only pulls 180W to 260W currently (Undervolted)P.S
I miss your kittty avatar. :*( <3
I'd be interested in your evidence for the claim that it 1. usually happens, and when it does it always 2. lacks quality/longevity/oc headroom.
Or is it a baseless/exaggerated/insufficient statistical data kind of claim? I act on the best information I have at the time, if you can prove the statement is true, I'll happily agree with you on it.
However, I want to add; let's not pretend that these "influencers" are not influenced by nGreedia, I am pretty sure calls were made, especially since said influencers made follow up videos bringing the OC headroom to the forefront when people were extremely disappointed with the performance uplift compared to the previous generation, and they heavily stressed that you can OC it one tier up, when that simply isn't the case, it's closer, but not the case.
The average user doesn't OC, they buy a card and they expect next generation uplift in performance. nGreedia most likely influenced in this manner, otherwards the backlash would have been even greater, and they sure didn't want to un-launch another xx80 card and slot it lower, but it sure as heck deserves the same treatment. Not just a personal experience, but this happened to me with my GTX1070 and with many others, they switched from Samsung to Micron, you couldn't nearly overclock as well and even if you did manage a good stable OC or not OC at all, your memory would fail much faster, mine did. It was well known that the Micron modules were sub par/ran more hot, there are articles about it. Many AIB's designed their cooling solution around the Samsung modules, those didn't need active cooling, where the Micron modules did. Anyways, scummy things like that, I and many others are trying to avoid a repeat. At the time EVGA didn't even bother to put thermal pads on the modules, oh boy, was that a screwup, thankfully, they still covered the self-repair-application of pads sent to their users, even if you caused accidental damage in the application attempt.
Anyways, people fear a repeat, this is why I check many things on W1zzards reviews before buying certain models, if the card is not on the TPU for review, I do not buy them.
This is me, concerning nGreedia:
They are the perfect candidates for feeding your ignore list.
It's actually rated at 32Gbps, but runs at 30Gbps. I imagine if Nvidia removes the +375 limit (unlikely) or it's bypassed (we can hope) it would be possible to already get very close to 40Gbps.
