Would a z97 4790k @ 4.8 Ghz bottleneck a rtx 2080?

I know how to use Curve mode.

This guy from nvidia says that voltage limit of the 2080 is at 1.068v. I use Gigabyte 350w BIOS with also 1.068v max voltage.



Please could you post a link where max voltage is shown at 1.093v?

What resolution do you plan to game?

Are you sure your bios is limiting to 1.068v?
The 1068mV is the normal voltage guarantee by Nvidia for the 5y lifespan he mentions, which Boost will max out if you don't use curve editor.

The real max allowed will be whatever your card accepts on the curve method I linked before, like you CTRL + L on something like 1200mv and while doing the -1 on each dot, the "white line" will stop moving.
On 2080 (and maybe the entire 20 series) this is 1093mV, which by the way was also on 10 series.
So that's Turing real max voltage locked by Nvidia, but you can only achieve it with curve mode (and above it only with special XOC bioses, but that's only for 2080 TI's as far I know)

I don't like the word "bottleneck", for me is more like the combination power of your setup.

On 1080p the CPU is a big part of gaming performance, so more likely you will be limited by your 4790k because a RTX 2080 wont really reach 100% GPU on 1080p unless played with some 9900K or threadripper.

This is not necessarily a bad thing, you will still have great performance limited by your CPU (on some reavy CPU games you may want to limit the FPS like 60/80 to avoid CPU spikes for a smoother experience)

Or go with a 2070 if you don't care about upgrading your display to 1440p anytime soon.

Well, time to post and join in the discussion here as well I guess .

I got a Gigabyte Aorus Xtreme 2080 a few weeks ago and so far it's an absolute beast on 1080p (yes I know it's overkill but it's pretty...)

Running it on 8000 mem and 2040 core now. It will run much higher, 2070 is stable as well, but games crash as it boosts too high on lower temps to like 2115 and that isn't stable.

Temps around 60-65c on custom fancurve. Amazing card so far.

Is there a workaround to make it not boost higher on lower temps somehow so I can just run 2070 constant?

Cars:
-Crashed: (not my fault ) '94 Nissan 100NX GA16DE (a.k.a. NX1600). Renault Laguna Phase I facelift '99 1.6 K4M. (Broke a strut and smacked a tree).
-Sold: '00 Nissan Primera P11-144 QG18DE, '97 Honda Prelude F20A4.
-Current: '03 Suzuki Ignis Sport 1.5 M15A & '03 Peugeot 206CC 2.0 RFN fully riced.

Welcome to the club =)

That boost behavior is really annoying and as far I know there isn't a way to disable boost.

But one little trick is to have your default profile w/o OC (or small one), and then have the higher OC on a second profile with a hotkey attached to it (I use CTRL + /), so after your game is open for a while and the card is on the usual load temps, use the hotkey to apply the higher profile.

I could do that with one of the G keys on my G710+ as macro yeah. Not that I need the performance on a 1080p 75hz display except for BF5 with RTX on Ultra in Multiplayer but yeah..

Thanks for the tip!

Yo, is it worth the extra £20 for the trio x gaming 2080 over the duke oc 2080?

Most reviews were at launch making it hard to judge how the cards have come along, the differences seem to be custom pcb and two 8 pins on the trio x also bigger cooler with the 3.0 newer fans. However alot of reviews putting the noise and temperatures the same if not in favour of the duke oc for some reason. Also the extra power doesn't seem to matter since all 2080s are power limited, so my question is the trio x still worth getting will I hit better oc's with it?

Really I am open to getting any 2080 except reference or asus strix since it's to expensive, msi seems to be the next go to choice after asus. The evga xc is only a two fan and the gigabyte gaming oc while the cheapest I do not trust as much due to general opinion being gigabyte qc not being as good as other brands.
