2760 default Suprim X
I get 2760mhz boost by default on my 4090 FE which I was very pleased with. I did try an overclock (at default power) and it is happy to do anything up to 2995mhz, for some reason it insta crashes at 3000mhz even if I increase power. As for memory overclock, it seems very stable although I haven't tried pushing it past a +600mhz.

That is quite low tbf especially for an FE.
Memwise I can go 1000 but it makes zero difference on my benchmarks so I don't bother. Core wise I settled on 2910 at 80% power. Not sure why I even bothered raising the core anyway, not like it struggles playing most PC potato games.

This is potentially a stupid question but if you don't ask you don't learn...
Am I right in thinking that for a 4090, you could pick up a corsair RM1000x PSU with the Corsair PCIe 5.0 12VHPWR cable and it should be fine?
If that's the case, why do you need 3 or 4 8pin PCIe connectors normally, but the corsair adapter is only 2 8pin from the PSU?

Because a normal PCE-e 8-pin connector can only deliver 150W.
But the PSU connector can deliver 300W. That's why some PCI-e cables have 2 x 8-pin PCIe connectors on them. It's also why the PCIe 5.0 12VHPWR cable, that can deliver 600W needs 2 x 300W PSU connections.

Yeah, I only overclocked to run a few benchmarks then set everything back to normal again.
Question I've just got one of these. Do you really need to use that stand that comes in the box?
Welcome and on TROH.

To get on the Roll of Honour all you have to do is post a pic with your user name on it of your RTX 4090
Not yet, still waiting to catch them with some in stock.
Having said that if something like the rumoured 4 slot Titan were to launch in the meantime, I would be all over that.
Soldato
There was stock of the 4090 FE for the last few days, Gone today but there should be another drop soon'ish.
If the Ada Titan comes out it's your obligation to get it, It's basically tradition at this point
Soldato
Yes and no. I run similar settings (70% power limit / + 140 core / +1400 ram) and it's faster than stock with lower power consumption, but if you run something that needs lots of power (dying light 2 with RT for example) those clocks are gonna drop rapidly cause of the power limit.
Thank you, that makes sense. I didn’t try a ram overclock, have you found this makes a difference?
Soldato
It makes a much bigger difference than the core this time around, and the difference in power draw by ocing your ram is negligible, something like 8 to 15 watts.
If i remember the numbers correctly I got 3% improvement by core ocing and around 8% by ram ocing
That’s really good, I’ll give it a go. Thanks.
That looks very good. I’ve never tried a vertical mount, what one did you use did it effect temperatures?Got the bracket so no more worrying bend on my cable by the connector. Thanks @Drumroll for the recommendation.
I used the Coolermaster V3 one in a Lian-Li O11D Evo. The Lian-Li is out of stock everywhere so this one was suggested and I'm glad I took the advice as it has some extra function over the LL one. Not sure if it has affected temps as they rarely go that high, but it's allowed me to put the 3rd 140mm fan back in the bottom as I had remove it to use the anti-sag thingy that came with the card.
