Radeon RX 6700, 6700 XT & 6750 XT users club

Mine used to go to an m.2 adapter when I was on Intel, but my current B650 board has two sockets coming from the CPU, so I'm fine with using only those... luckily, because the main x16 slot is shifted down by one slot, so the bottom one is the only breathing room for the graphics card.

Seriously, what were they thinking at Gigabyte with this design, when the x1 slot becames unusable with any even somewhat modern GPU... they could've put it above the x16 4.0 slot and move the M.2 slot a bit, but nope.

edit: I could quote AVGN on this one. "no, they were not thinking"

Valid points there if you don't have a box full of graphics cards like I do

Agree on the HDMI part, my only HDMI goes to VR headset. And I have to use a DP-DVI cable for connecting my secondary monitor (ViewSonic 24" 1080p VA from 2015) as it has only VGA & DVI.

If the GPU shortages of the 1st ETH boom, 2nd ETH boom, and pandemic-fuelled scalpocalypse haven't taught people to hang onto at least one backup GPU, then nothing will

That's probably for air-cooler compatibility these days. Most ATX boards now move the primary PCIe slot down one to give clearance for 140mm CPU coolers. There was always a shortout risk with chonky towers and graphics cards without backplates in the very top slot. Most GPUs have backplates now and with a top-slot GPU that's enough to even interfere with some of the more plasticky/decorative 120mm towers. The added bonus with this more common PEG graphics in slot 2 like ATX boards is that the CPU's M.2 slot doesn't get cooked by the GPU exhaust, which is something of significant importance with hot GPUs and PCIe 4.0/5.0 SSDs which often have heat problems in ambient air, let alone the 80C air-frying from a GPU.

I feel that if you're genuinely trying to put a triple-slot card into a micro-ATX case that is so tight there's a solid, unventilated wall below the bottom edge of the board, you've already made some poor component decisions and *then* you need to start looking for a board and cooler that are top-slot compatible. There are ways to make it work but the advent of 3.5-slot GPUs has meant that mATX and SFF are going to need more careful component choice than ever.

Yeah. My old mobo had my 970 Evo Plus cooked because it was right at the GPU lol

AFAIK the M.2 slot under the graphics card is a death sentence in a gaming rig. NAND doesn't like getting hotter than about 85C, the SSD controllers throttle around there too.

Most Nvidia cards target 83C I think, and that doesn't mean the exhaust air will actually be 83C, but even if it's only 70C air coming off the GPU, the SSD needs an ambient delta to shed any of its own heat at all!

I still suppose that a "normal" gen3 drive will be fine on the 2nd slot of my board.

It's kind of an AMD thing these days. My MSi Pro B650M-A has the same layout... so back to the original topic: an iGPU is a must when my graphics card only has one HDMI output.

Both with my old 1080 Ti and with my current 6700 XT this ain't no problem. Never seen temps above 70 degrees. Now, with a new PC case, temps dropped even lower so my SSD never goes beyond 60 °C.

Just don't let your video card reach these 80s in temperature and you'll be fine.

 

[amd64skater]

Where did you read this nonsense? CPU-wise they are identical and F-CPUs are weaker in general due to their AV1 lack. Say, watching videos on YT loads CPU cores in F-CPUs whilst iGPU-fueled ones use iGPUs for that leaving more room for more important tasks. Be my iGPU fine, I'd no doubt enabled it.

This needs tests.

It doesn't. I can't learn what error it crashes with, these crashes are too dead to be useful. Nothing I can gather from Event Viewer. "The system has been shut down unexpectedly," and that's it.

When I do get a CPU I have never had bought one that had a integrated graphics built in unless I was not going to get a video card. I just keep it simple dedicated CPU and GPU. Now If I was going with an Intel setup I would have bought an Nvidia card instead. But when I go AMD I use all AMD products.

Ah, so I'm not the only one who upgraded from 1080 Ti to 6700 XT. I was surprised that the actual performance improvement was way bigger than I thought it was; in synthetic benchmarks the difference is way smaller than in games, though I haven't even tried gaming at 1080p with this (I bought my 4K monitor almost at the same time as 6700 XT).

Nice. Here I came from an RX 480 4GB lmao, couldn't run anything at 1440p.

Apparently, all AM5 CPUs (will) have an iGPU now, which I'm quite happy about. My endless hunt for GPUs with two HDMI outputs is over.

I just needed more video cards. This is a lucky coincidence I had enough money for a new card to be better than my old one.

 

[Chrispy_]

Yes. I have a heatsinkless SN570 as a games library crammed under my 6700 in the dimensionally-challenged HTPC. It's a ~65C without a heatsink which means the controller puts out almost no heat at all.

The GPU exhaust will mandate that it's always warm during gaming, but the important thing is that it's not at thermal throttle temperatures and doesn't generate enough heat of its own to stray far from the temperature of GPU exhaust (which is probably only 50-60C in the case of my underclocked, undervolted GPU)

The SN570 is a cool drive though, and an undervolted card puts out less heat than normal. I wouldn't want to generalise that all gen3 drives are fine underneath all GPUs. I own a couple of hot gen3 drives, and the 3070 I had in there briefly was definitely on the toasty side for that case.

 

[Kodehawa]

So I realized the 6700 XFX model has something interesting going on. At *stock* clock speeds AND stock power limit of 138W PPT it hits the clock target, which shouldn't even be possible.

You might ask how? You're giving it almost no power.
Well turns out, it runs at 1.15V, not at 1.2V.

Undervolt it to 1100mV and you get... 2520 at 138W!

Wow that sucks. Looks like I will be choosing pretty hard on my next build. No need now with what I got now for a while.

I'm honestly trying to understand why you avoid iGPUs but it seems impossible. Can you elaborate?

 

[Chrispy_]

I'm honestly trying to understand why you avoid iGPUs but it seems impossible. Can you elaborate?

I'm also curious what his hatred of IGPs is.

A tiny IGP that you don't use isn't a problem to be avoided; There are loads of transistors in modern CPUs that consumers don't need or use - either there for other SKUs like the Ryzen Pro, Threadripper, or EPYC, or there solely to aid internal testing and manufacturing during the CPU production. If you don't need the IGP and disable it in the BIOS, it's yet another bit of silicon that you don't use. It's far from alone in this regard on the CPU package.

That unused silicon is desirable to end users even if it's "wasted space" because the die area those transistors take up is still able to soak up heat and provide additional contact area to the IHS which obviously improves thermals and ease of cooling. It's not like it's costing you more, It's just there anyway.

 

[AusWolf]

Why? If you don't want it, just turn it off in the BIOS.

FYI - Even Intel "F" CPUs have an iGPU, only that it's permanently switched off.

 

[Splatink]

Yeah, I got the 6750XT variant and it does 4k 60 just fine. Overclocked too.

Ok Integrated graphics, by placing both a CPU and GPU on the same chip, one (or both) of the processors will be limited. Or, in other words, you cannot place both a CPU and GPU on the same chip without limiting one (or both) of their potential processing power. Ok that it explains it. Call it a myth or urban legend I just have no need for a iGPU. I'm just not a fan. Now I know my laptop has it and to be honest I should have bought one with a dedicated GPU.

 

[Kodehawa]

Huh. My GPU seemingly just died out of nowhere.

I woke my PC up from sleep, the entire screen glitched out and it won't work anymore. It glitches out and gives a black screen the moment Windows loads.

I tried reinstalling Windows, same outcome, when the drivers auto-install, it black screens away.

What I don't quite understand is that in a linux LiveUSB I still get an image, but trying to load into (even a completely fresh) windows install is no-no.

Tried the whole reseating GPU, RAM, default bios settings, etc. Nothing seems to do it. Ugh. I don't even know how long it'll even take to RMA this.

Did you modify the bios in the gpu? If so you need to flash back to stock.

 

[Kodehawa]

No

 

[amd64skater]

No

Yeah weird it may be dead. Did you try a different output. Not sure what yours has. Like mine 1 hdmi and 3 display ports.

 

[3x0]

There's no BIOS modification possible on RDNA2 anyway...
