 You didnt talk about ur overclocking procedure, but i can tell you, like actually i oc my ftw3 ultra at +115 and + 800 and if i apply +30 gpu core voltage, many games will run fine but others will crash sometimes for sure and if i apply +60 most of my game will run fine but 2 or 3 game will still crash after 10 or 30 minye, even hours after i start play and if i apply full +100 i have no crash with alllll games.
 
 If you oc ur cpu ram it can be the issue, even it pass stupid stability test, if your cpu cash is oc this can be also an issue.
Try disable oc on cpu and memory if you still have this issue. Sometime it can be a bad cable, pci cable, power cpu cable and is your psu is plug direct in the wall socket or if you plug it on cheap power bar and while your pc running you touch the psu plug and it feel hot. So many thing can happen, sometime its weird and really hard to catch a problem. Did you try gaming hours on another card and all is fine ? Is this problem begun with ur new graphik card ?

Ive run the cpus at stock, pbo, pbo edc bug and all core (4.2-4.3ghz)
Ram ive tried default and multiple different timings. Ran memtest, tm3, occt and all that jazz. 
The 3090 I can set anything from +0 to +160 core and +0 to +1000 on the memory. Regardless I get power limit, perfcap reason the whole time. Core will maintain 1920-1960. Ive even put my pc in the freezing garage and got worse results. 
It seems the gpu does better around ~60c.
Tried different wall plugs, surge protectors and power cables. 
My evga 1080 and loaner 2070 never had a problem like this. 
Ive been messing with this over the past few weeks. The card just isnt able to preform correctly.
I game for 35+ hours a week so im pretty familiar with my pc. 
Im still hopeful we can resolve this some way. 

 Try stop oc your 3090 for 2 or 3 day and keep gaming, do you have the latest software to oc ur card, did you tried clean gpu drivers and réinstall it.
 
 Its possible a card can be defective and you have a warranty and you can open rma under your member product too.
 
Last week ive played 4 or 5 games without issue then played call of duty cold war...the campain crash at some point, the issue was my memory ram oc at 3400mhz from 3200mhz, call of duty use near all your ram and that was the issue, but on memory test my overclocking ram at 3400mhz pass all the way, i also can bench port royal 24/24 with my ram at 3400mhz coz its using small amount of ram. +190 oc on gpu seam high too me, i cant do that, max around +170. My memory i can do +1250 but i dont put this...just +800. Benchmark can pass with higher clock set but games didnt like this kind of oc for long session.

If you want to play games use XC3 BIOS the best for all cards with no mods and Air, and maybe it will run better with a waterblock installed
If you want to bench use XOC or other BIOS posted early here and try to put the card to top on max 60C (see sensors on ICX) and pump the max you can on CPU and MEM with third timmings tweaked
 
Otherwise it's a waste of time.

If you want to game at high memory clocks with your GPU you must be first stable (you know this of course) but instead of using all the sh*tty software that's out there to test RAM just use Intel Burn Test on 10 passes AUTO, if you manage to pass that then turn the PC off, enter again and run it 5 passes then 10 again, if it's stable you are ready to go!!!
 
or...a much better way
 
Use AIDA64 and go straight to the FP32 RTX test and then FP64 RTX test if you get to pass that in that secuence at least 3 times you are also ready to go!!!
 
I've used these methods since ever and they work pretty perfect and fast.
 
btw: I forgot (and you may also already know  this) adjust MESH (if using Intel HEDT) or Ring Bus/ CPU Cache (If using Intel Desktop) + VCCSA and VCCIO Voltages
 
Cheers, Sergio!

Also hit 500w running Port Royale:
 
 
 

hey i was woundering why i have the xoc bios with clocks of +160 on core and +700 with 100 on volt and max power at 119 but still barly touch 420 watts

TheHyperMatrix hi :), what is the card in your hand now, coz you change your graphik card like i change t-shirt hehehe. I not sure if you have an hydro copper or a ftw3 ultra with hybrid kit or another one ?

Haha well I sold the Strix.  Have an FTW3 Hybrid right now.  Waiting for the FTW3 HydroCopper to ship out.  And still trying to get on the KingPin notify list.  :P

No problem! I heard back from the Product Management team. They noted that it is a beta bios, and as such may have bugs and issues still to be worked out so it may not work properly for everyone yet. They are working on an official release, and that they have enough data at this point. They don’t have an ETA though on when an official release will be available though.
 
I hope that helps!

 
Hope this helps, i for one am happy purely because they know there is a problem. So far im happy with the silicon just sucks it can get past 450w.

What worries me is that EVGA is usually very quick with these types of fixes.  And the fact that it's affecting some cards and not others becomes even more concerning.  Just as an FYI though, if you flash the XC3 bios on your FTW3, you'll be able to pull around 500W-520W.  Software will only show max draw of about 300W, but it will indeed be 500W. 

Guys I'm still using PX1 Version 1.1.1 and NVIDIA Drivers 457.30, anyone noticed any improvements on new version of PX1 and new NVIDIA Drivers ?
 
Thanks to all, Sergio!
