NVIDIA RTX 50 SERIES - Technical/General Discussion

I have 2800 at 0.895v and +3000 on the memory. During most game sessions maxed out 4k (some with DLSS) it will maintain a clock of anywhere between 2550 to 2650.

In my testing so far I have seen up to 81% power usage and just under 500W (I think 490) with 2827MHz @ 0.900v. I think that was one of the 3D marks, maybe steel nomad or time spy extreme. In games it is more like low 70s power usage max. This tells me these cards should hopefully have a little gas left in the tank for next few years with these optimised settings. Games always rely on being well optimised themselves but I think this card performs so well undervolted. I don’t have any interest in shunt modding or using XOC bios or anything but the gains from overclocking via that route are amazing. This gen card is actually very impressive at the top and low end of the power scale.

Do you change the power limit slider at all ?

I have looked into that. Some undervolting guides recommend maximising it to avoid hitting any power limits. I leave it at 100% and I don’t lower it. I think the undervolt should be dialed in to try and avoid hitting power limit at all. When you undervolt you don’t want anything else to drop the clocks and the voltage and power should be so much lower anyway, so you don’t want power limit coming into play as well. If you want to use less power then undervolt more, in my opinion. It’s all interesting though.

Not sure if this has been posted but "apparently" there will be a 48GB 5090, Nvidia showed during their "Designing the Founders Edition" video, A render of the 5090 PCB with Samsungs new 3GB chips, It could just be a mockup though.

From what I've seen the core will remain the same, Just swapping out the 2GB chips for 3GB chips... although I imagine the 48GB version will cost silly money... sillier money ?

Samsung GDDR7 3GB modules now available for DIY purchase in China, RTX 5090 48GB mods incoming? - VideoCardz.com

SAMSUNG 3GB memory modules now on sale The production increase is likely ahead of the upcoming SUPER refresh. It is no secret that NVIDIA will expand the use of GDDR7 memory featuring 3GB capacity to more graphics cards. Currently, in the gaming series, only the RTX 5090 Laptop GPU features this...

Here's a list from the article showing what could be possible...

Bringing back 12GB to the non-Ti version of the 5060 will be good for those that only need xx60 level of compute but have hit VRAM limits on the current 8GB version.

I'm guessing the render of the 5090 PCB further down the page showing the 3GB memory was actually the RTX 6000 Blackwell workstation GPU as the video did come out a fair few months prior to the RTX 6000 Blackwell release.

Probably. It would be a bummer if a 5090 FE 48GB came out because I've already used up my 1 FE credit for this generation already and I would have to go 3rd party for it instead.

The core would be the same, only memory would be theoretically increased, is 32GB not enough for you ?

Unluckily for me I'm into local text generation and moving from a 4090 to 5090 isn't that big of an upgrade. If it was 48GB from the get go then that would have been better. A month or so back I was eyeing up RTX Pro 5000 48GB but it only comes in blower...

...whereas the 6000 96GB comes with a nice dual fan FE style but costs £8k...

Horrendous product launches, and everyone and their nan knowing the real products (the Super line) will be coming a little later down the line.
Not suprised that they are sitting on shelves.
 
Dicehunter said:
Yeah the only "real" product was the 5090, everything else was quite lacklustre

Seen quite a few people who cheaped out on. 5080 proclaiming how they don't need a 5090, only to flipflop back the other way and now it's of course the best thing ever lol.

Makes me wonder how much money was lost compared to what it would've just cost in the first place to buy the 'proper' card.

I had a 5080 and it was a fine card but then went 5090, Not because of general flip flopping but I had a serious health scare and decided I wanted to have fun just incase my health issue gets worse and thought "bugger it" and got a 5090.

Great decision, beast of a card. I just wanted the best, not getting any younger.

What was the trigger then? you went from saying you couldn't justify a 4090 because your 7900XTX was giving you a "solid gaming experience" and you could easily leave ray tracing. Then like a month later shopping for a 5090 and singing RT praises lol.

Do you think you'll keep this card a while or go for generational upgrades?

Probably AC Shadows. Wanted to play it from the sofa on my second screen in all its glory, needed two HDMI ports, didn’t want to use a switcher. The 5080 wasn’t enough of an upgrade and a 5090 was only a grand or so more.
