Do Epyc CPUs exist with the high clock speeds you want for gaming, though? I haven't kept up, but I thought they were a lot like Xeons and Threadripper, where you get a bazillion cores, but they all run at 2.5GHz.

Was it you that posted on my Youtube channel a few weeks ago about how you want me to set up a Discord server? If so, this is the closest thing that's likely to happen to that. I'm almost ashamed to admit this, but... every time I try to use Discord, it's borderline unintelligible to me...

Does the system post if you plug in a different graphics card? If he really dropped the card on the motherboard, it's possible there's damage to either the motherboard or the graphics card that would cause it not to post. MagnusFarseer, can you post some photos of the card and that part of the...

What happened after a few seconds? Did it crash, or did you just stop it?

Is that cockroach diarrhea around the socket?

Now that you can just go find one in a store, i keep thinking about how maybe I should finally get a 4090, but then I think about what games I'd play with it, and I come up empty. Other than DCS World, the only game I feel anything other than inescapably "meh" about is the expansion for Horizon...

Ooh! Me me me! I'm one of those corner cases! https://hardforum.com/threads/pci-e-bifurcation-on-the-asus-pro-ws-wrx80e-sage-se-wifi-how-crazy-can-i-actually-get.2019992/ If I had it to do again, I'd at least consider these for that machine. The price tag is a bit steep, but for our oddball...

The damaged portion of the PCI-E connector is the part that primarily carries power, clock and link signals. The worst damage appears to be pin A1. If the card works at all, I doubt (but could be wrong) that that alone is the reason for the graphical artifacts on the display...

You could probably replace the whole heatsink with an aftermarket one, like an Arctic Accelero. It makes case fitment even harder, but it'd be a hell of an upgrade over that puny stock one. https://www.arctic.de/us/Accelero-Xtreme-IV/DCACO-V800001-GBA01 I'd try to reuse the original thermal...

It'll be fine. Clean the die and heatsink, put fresh TIM on it and send it. If the fan works now, don't worry about replacing it. You can always replace it later if it fails. But yes, you can replace it. Punch that part number into Ebay, and you'll probably find one.

Or just live with the card running a little hot. 80 degrees isn't the end of the world.

Remove the screws from the back of the board and the heatsink should come off - you may have to pull gently if the thermal grease is old. 1.0mm thickness is the normal size for thermal pads on this sort of thing, but you'd need to take it apart and measure. Pretty much any pad material should...

What do you have to ground on the negative side of the fuses you replaced? Also, are those fuses still intact, or did they go open when you tried to power it up again?

What resistance do you have on the 12V pin of the PCI-E slot connector? Also, check each of the major logic rails for a short and for function. These cards have at least three. I forget the official names, but more generally, they are: VCore - Core power. Should be something like 1200...

You have a short to ground on one of the 6 or 8 pin power rails. Check the resistance from the negative side of the fuses you replaced to ground in ohms mode, NOT SHORT DETECTION mode. What I suspect you'll find is that on one of them, you have something like 600-1200 milliohms. If that's the...

When it happens, do you get the hardware disconnected sound, like you get when you pull out a USB drive? I ask because it's possible for this to happen when the GPU crashes or shuts down. You could check this by probing the card with a multimeter to see if the GPU power rail is still at the...

Does it happen in more than one game?

I'm pretty sure there's a free version that should be good enough to test this.

It'll be fine. Nvidia-based graphics cards have very complex power management for just that reason. You can't push more power into the card than it can handle - it regulates its usage on its own. Your findings are interesting, though. It would be neat to see some benchmark results from...

It seems like in this thread, he's asking if his 4090 could maybe have been swapped out with a 4080 PCB by whoever returned it to Micro Center, whereas before he was just asking why the framerate is the same with the 4090 as it is with a 4080. Assuming this is the "TUF" model, it looks like the...

Oh, yeah, I remember that. I wasn't aware that those counted as "large." I'd never heard of them before that story broke.

Say what? Who got caught doing actual crimes?

I don't get why they'd lie. Isn't the video more interesting if they paid $15K for that thing? I totally sympathize with you, though. I'd be upset too if they swooped in and sniped my stuff AFTER the auction ended.

If Linus wanted it so badly, why didn't they just bid enough to win the auction? I don't see what's so wrong with them trying to reach out to the person who did win the auction and come to some sort of arrangement, though. If they're really offering to pay more, the auction winner could...

What happens if you run FurMark?

Pin 4 is on the other edge visible in your photo - the edge perpendicular to the markings. It looks like it also connects directly to a through hole, but the cap usually very close. I'd look for any MLC caps directly behind that IC, and use a multimeter to figure out which ones are connected...

According to the datasheet for the SIC788A, the bootstrap capacitors are connected to pin 4. https://www.vishay.com/docs/62985/sic788a.pdf If none of them are obviously running hotter than the others, that's probably not it, though. Bad current sense resistor is another (remote) possibility, I...

The bootstrap capacitors should be located very close to their respective VRM power stage ICs. You'll have to look up the datasheets and figure out which ones they are yourself, but I may be able to help you if can you share a closeup photo of the power stages, or read off the markings and post...

That sounds like it's probably normal. There are a few things you can try next, but one thing I might try is to let it sit there at the post screen for a minute or two, and then feel the back of the board for any obvious hot spots. If you find any, troubleshoot that phase. The power stages...

That's probably good news, in the sense that it means the core and memory controller IC is most likely shutting down due to one of its various built-in protection functions. I believe the controller on the 2080 is a UP9511 or UP9512. Datasheet for the 9511 linked below...

What happens if you increase the voltage a little? Does it still crash? Also, when it crashes, are we talking immediately when you start a game - no frames rendered at all, or does it run for some period of time (seconds? Minutes?) and then crash? There are a few possibilities here; one is...

When you reduce the core voltage, does it work normally, other than being just a little slower?

Nothing wrong with PNY. In fact, they make a large share of the workstation class cards (previously called Quadros). I'd expect them to be textbook reference boards, and perfectly fine for the purpose of playing games, doing desktop stuff and so forth, but maybe not the greatest for...

I'd use the KPX, but I seriously doubt it will matter unless you're doing some sort of competitive overclocking.

It seems to be the case that, if you want a 4090 of some variety, you can now get one with just a little bit of leg work, there will probably always be shortages of the 4090, at least until a 5000 series exists. The Founder's Edition really only exists for the purpose of making the claim that a...

Buy whatever hardware you need, when you need it. The current crops of defects have been overblown. With respect to the 4000 series 12VHPR connector failures, it's a very small number of failures that have actually been seen, relative to the number of cards sold, and as far as I know, most...

Something I noticed, back when I made videos about graphics card repairs for Youtube, is that most of the audience was in the parts of the world that don't have such strong trade ties with China and Taiwan, I assume because the people there are less affluent, but it seems like it was more of an...

The circuit this capacitor is a part of is such that you’d need to actually test the board with a game-like application to tell if it’s working or not. Just booting it up won’t tell you much unless you totally fucked up the repairs.

I’d need the heatsink in order to test it after any repairs I did.

Did you tin the iron? If you did, then some of the solder you applied to the iron should flow off of the tip and onto the joint. You can add a little extra to the pad while you've got it hot, if you need to. That's a huge pad - you'd have to add a crapton for it to start bridging to anything...
