Hey all, hope someone can help shed some light here - or at least offer an opinion?
I have a Gigabyte Vision 3080 from Overclockers way back when they first came out, and that card has been rock solid.
I have also managed to pickup an Asus Tuf 3080ti 12gig card in the last month or so from a project that got wound down at work. i thought it'd be a drop in replacement for my current non-ti 3080, and a 10% uptick in performance for zero cost, so, hey, worth it right?
omg wrong. but i can't figure out where i'm going wrong - i suspect power supply, but hoping to get a 2nd opinion...
so, the Asus card looks like it works fine. i can run all the benchmarks in 3D Mark with it, I had the lightspeed benchmark on stress test for hours with no crashes. Furmark runs perfectly for ages too. GPU-Z is reporting that the Asus 3080ti card is pulling about 360Watts power, versus my original Gigabyte non-ti 3080's 350Watts.
everything looks great. except actual games with the Ti card.
Valheim crashes back to desktop anywhere from 30 seconds to 3 minutes - doesn't matter if you leave it on the initial character selection screen or jump into a game.
Shadow of the Tombraider graphics benchmark never completes. the actual game again crashes back to desktop...
Redout runs fine for a while, then crashes out to desktop.
i'm hoping it's "just" a power supply issue and that the Asus card is good, just that it turns out i've been riding the edge with my current 685W power supply running my non-ti 3080 and not known it.
trouble is, i have nothing else i can test the Asus card in to make sure the card is fine. and as my PC is an ex-office Dell Precision workstation, getting an uprated PSU is a bit of a nightmare.
does this sound like it is a PSU issue, where the benchmarks and stress tests run fine, but games don't? If it was a power problem, wouldn't it wipe out the whole PC with either a bluescreen, or a reset? I know about the "Transient Load" issues the 30 series cards exacerbated from the 20 series. but if i could run a 3080, a 3080ti shouldn't be *that* much heaver to run?
Specs otherwise:-
Dell Precision 5810
Xeon E5-1650 V4
128gig ram (8x16gig DDR4@2400) also tested 64gig with a single quad channel set of 4x16. no change in the symptoms.
Samsung 970 EVO nvme in a pci-e 4x to nvme adapter card
685Watt PSU
Windows 11 latest
Nvidia drivers v511.23
i've had some duff luck buying a higher spec Dell PSU off ebay. basicly dropped nearly £170 on what was supposedly a 1300Watt version - and it arrived DoA, and Dell won't do an out-of-warrantee repair as apparently it's not a supported PSU for this system - unlike what was advertised on the ebay auction, and the listing was "no-returns". ergh. paid all that money to effectively ship some e-waste from china.
anyway, all said and done, after that PSU experience, i don't want to throw money away guessing. now i'm at a place where i want to somehow test this card to make sure the card is known good before i carry on, either 1. get my Dell up to scratch, or 2. build a new machine to host this Ti card.
all thoughts and ideas welcome
