Hi! I'm thinking about buying an XFX Radeon RX 6700 10 GB (SWFT 309). This is the only card out of all 6700s that is available in my country. I want to undervolt this card. I'm ready to lower the frequency as well.
So I have a few questions. First, a general question.
- Will the voltage and frequency reduction capabilities offered by MSI Afterburner or another third-party program be enough? I'm asking because right now Adrenalin is buggy with my 5600G iGPU. So I want to have a second option.

I'm not sure what you mean by buggy, but Adrenalin is pretty fine with any 6000 or 7000 series card.

i had a game, that made the computer completely crash ... can't remember which one, aside it was an indie ... since it did not happen recently

but i had to reinstall the whole drivers in integrale, GPU-Z was showing the card with no shaders, 0 mhz core/ram speed and non functional for d3d ...
ofc it was not a driver issue but a game, and since it was an indie game, nothing to blame on AMD but rather on game engine compilation

other than that, never had any issue with Adrenalin on my RX 6700 XT since i bought it and i kept it updated to the latest version without any rollback.

I am not sure, maybe it's my bad. I just hadn't had any problems before. But I installed Ryzen Master and Adrenaline yesterday. After that, I got frequent messages, something like the driver stopped to answer with screen blinks. I uninstalled Ryzen Master. Messages and blinks became occasional. After Adrenaline's uninstalling, I don't have any problems. Maybe I shouldn't install Ryzen Master and Adrenaline together, or Adrenaline is not for Ryzen 5600G's IGPU. But I want to know, do I have good alternatives for Adrenaline, or not

- What results did you achieve? I am most interested in power consumption and fan speed.

Adrenaline kept resetting my undervolt each time I restart PC. Had to use MSI Afterburner, all good.

Kinda underrated cards. Mine is fine for 4K60. I have this one: https://www.techpowerup.com/gpu-specs/powercolor-fighter-rx-6700-xt.b8736

I just picked up one of these cards for £287 (brand new) so I have finally upgraded from my RX 570.

It will be here on Tuesday.

I've never had Ryzen Master installed (I don't care about CPU OC), and I've never had any problems with Adrenalin.

XFX Radeon RX 6700 10 GB (SWFT 309)

I got her older sister, RX 6700 XT 12 GB (SWFT 309) and due to excessive mining and most probably unfortunate binning, it's not that great at UV but I managed to squeeze 2720 Max MHz @ 1150 mV for non-RT and 2720 Max MHz @ 1180 mV for RT scenarios. Power consumption is ~5 W less than original (2644 Max MHz). I have excessive cooling and I don't really mind squeezing more off this GPU but I'm hard stuck at 2720 MHz, it just can't do better than that.

Non-XT GPUs are expected to be hard limited by wattage limit in BIOS so I don't expect you to get anything more than 2700 MHz (~2650 effective MHz). XFX RDNA2 GPUs have overkill cooling solutions so I don't think you really need UV here but you do you.

Backup your important data, reinstall your OS, install 3DMark + Superposition and get Adrenalin running and start with setting voltage to 1100 mV in Adrenalin. If it doesn't work then add increments of 5 mV every time after crashing in benchmarks. Once you got to the point it doesn't crash anymore you just add another 5 mV on top of that to be completely sure and that's it.

Lowering your frequency is only necessary if you're running into stability problems with stock voltage. Getting it a couple dozen MHz higher won't hurt whatsoever.

And yeah, you're limited by narrow 160-bit bus so overclock your VRAM to the max. Don't worry, the 2150 MHz number is absolutely safe for GDDR6 installed on these GPUs and they can do MUCH faster than that. It's just AMD not letting us OC their GPUs properly (I'm inclined to think it's because properly OCed GPU will be on par with a higher tier model so people would just buy lower tier GPUs and OC the snot out of them just like in good ol' days when you could double the CPU and GPU performance by pressing a couple buttons).

Ignore the junction temperature, and your hotspot temperature should always be a double-digit number. Anything beyond 99C is unsafe.

Adrenaline kept resetting my undervolt each time I restart PC. Had to use MSI Afterburner, all good.

This has happened to me every time I set as default profile any undervolted that isn't stable enough.

Disabling fast startup resolves my AMD GPU problem

Little bit of a PSA kinda post. Using a RX 5700 XT in my main build for a couple years until I upgraded to a RX 6900 XT. Later building a separate SFF system and repurposing the RX 5700 XT in that SFF system this issue got even worse it seemed. (to clarify, regarding the RX 5700 XT in the SFF...

This detail is interesting as my 6700 XT is the only AMD GPU I own where I can max out the VRAM speed with zero crashes (2x 5600 XT, 6600 XT, 6700 XT, 6800 XT) though the 6600 XT goes to 2160 with no probs, it just has a crazy 2400 MHz top speed.

 

[Macro Device]

6800 XT

Care to tell me more? Does it crash upon reaching 2150 MHz? Extremely rare case if yes.

5600 XT

This is not RDNA2, these behave differently.

 

[Lew Zealand]

Yes it will crash in Time Spy and Port Royal at 2150MHz VRAM so I don’t even try in games. 2130 seems fine but I stick to 2110 because tiny fractions of performance aren’t worth the stability risk.

This is not RDNA2, these behave differently.

It’s still just VRAM though and both my 5600 XTs will go from 1750 to 1830 but will occasionally crash out at 1860.

Roger that. Peculiar case, still.

It's far more complicated than just VRAM modules. It's also about vBIOS settings, GPU architecture, PCB layout, PWM controllers and a whole lot of other things I honestly have no clue what they are made for. That's why maxing soft limited RDNA2 VRAM is common and maxing hard limited RDNA1 VRAM is uncommon. Hardware in RDNA1 is just not made for maxing this out, unless you commit to extraordinary tweaks on lowest levels of how they are programmed.

IIRC, I was getting a fatal WHEA with "Cache Hierarchy Error" as the reason, with VRAM bumped up on my RX 5600 XT.

but i had to reinstall the whole drivers in integrale

Remember to block Windows Update from installing drivers.

nah, read the whole post ... not due to a driver update, i never had a single issue with AMD driver update.

ofc WU is blocked, but that one was, as i wrote , from a game crash.

It's a Solid GPU I got mine few month's ago and so far it's working perfectly fine and as @Kissamies said I also use it in some games for 4k/60Fps gaming for example War Thunder on maximum details in 4k working great on this card on some more demanding games you can use FSR so it's all good my only nitpicking is that GPU is not that great for overclocking but more or less all 6000 series is the same they have locked bios....

Yeah it sucks that the memory overclocking is artificially limited.

- What results did you achieve? I am most interested in power consumption and fan speed.

If it's at stock clocks, I can pull the voltage down by ~-100mV. Any OC makes UV impossible for me. The card runs a bit undervolted stock (at stock PL of 138W it has a GET voltage of 1.145V -core voltage of 1.110V- when reaching clock speeds around ~2380MHz)

The card is super quiet (can't even hear it) if you run it stock. If you're me and run it at 175W with 2700+ clock, then it can get a bit louder.

Though that's silicon lottery tbh, but I mean... the card uses ~130W stock, so it's really low power out of the bat.

Thanks a lot. This does fix my issue. I thought disable fast boot on Bios was enough, never thought there's a fast startup in Windows settings.

Hello guys, update on my gpu.
It was just my terrible case and hdd "management", those drives (3.5") where blocking air to go from the front of the case to the gpu and cpu.
Added a fan, re-arranged the drive so air can go throught the cage and now everything is good.
gpu (edge temp) minus 20c
gpu (hotspot) minus 15c
cpu minus 20 to 25c
drives minus 10 to 15c
All good now

Anyone else having problems with the newest (23.10.2) drivers? Otherwise these seem to work but now I can't open the AMD software center. Well, overclocking works with Afterburner so I can live with it.

Nope.
well yes but it was doing it with the one just before.
i cant have adrenalin soft + driver for igpu and dgpu1 and also have driver only pro for dgpu2

Well I'll try DDU if that solves the issue.

I'm loving it so far. Frame rates have either doubled or tripled from the RX 570. A positive about not upgrading every 1–2 years I guess.

The next step is to upgrade to Zen 3 as I know I can get more out of the GPU in less demanding titles. The 5700X is a sweet price right now at £180. That's what I paid for my 3600 back in 2020.

215EUR for 3600 in 2020, 190EUR for 5800X in this month. You won't be disappointed with a Zen3 8-core.
