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

I was meaning a flashed bios. Sorry

 

[RJARRRPCGP]

No

Looks like another variant of the infamous "Windows 11 blank screen with monitor in "normal" mode". Where it doesn't report no-signal.

It's possible that you need to disconnect from the internet and use DDU then reconnect to the internet and then get it from AMD.

Doesn't work even on a fresh install, sadly. Maybe the DP cable is broken, since reconnecting it works for a bit, but I need to get an HDMI cable to test.

by placing both a CPU and GPU on the same chip, one (or both) of the processors will be limited.

AMD's IGP is on the IOD die, Intel's IGP is on the same die as the CPU, AMD's is not on the same chip as the CPU (CCX chiplet) unless you meant the whole package as a chip.

back in the days i compared a Xeon E3-1270 V2 versus a i7-3770 and aside the 8 watts difference between the 2 processor, no other performances differences at all using dGPU with IGP off on the 3770.
i also had no need for an IGP, until i did ... for flashing a GPU... and switching to IGP was faster than getting a weak dGPU, luckily the only time i needed to do so ... i had a i5-2400

well nowadays i have a weak @ss GT730 DDR3 2gb in my i7-3770 "HTPC" so, in case my 6700 XT need a flash i have something (i will replace it with a RX 6400 GD6 4gb later, so if i upgrade my R5 3600 for a R7 5800X3D i will have something a tad more powerful than Ryzen 4 IGP in case my dGPU go belly up outside warranty clause or periode)

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.

It's not dead if you get an image in Linux. These are some BS Windows shenanigans going on....
Side note: I stopped using Windows sleep function on my desktop many years ago. Pretty sure there was an important reason for me to do that

Call it a myth or urban legend

It just makes no sense. None of my fast timings issues comes from iGPU. My iGPU was broken and I disabled it so it can't be no reason for nothing.

You don't need it and it by some absurd reason spoils your UX, you disable it. But only the faulty iGPUs are prone for doing that.

My RX6750XT profiles that have being tested and work well are the ones below. I have posted those data in another thread months ago but in this thread that could help some people having a Navi22 based GPU.

MaxClocks (MHz)	1994	2294	2590	2670
Voltage@AMD driver (V)	1	1,15	1,175	1,175
Voltage@GPUz (V)	0,825	0,9	1,05	1,162
Max wattage@AMD catalyst (W)	90	130	175	210

The clock figures are the max ones and are very close to the ones set in the driver suite. To get the real power draw we need to add another 25-35W to the figure showed at the catalyst suite. Also the last profile on the right side is the auto-undervolt one.

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.

Then, like I said, switch it off in the BIOS. Problem solved.

Edit: Having an iGPU is only a limiting factor when the CPU+iGPU+other's total power requirement is higher than the power target of the whole package. Speaking of which, you do realise that there are various other parts in a CPU besides the CPU cores, cache and iGPU that consume power, right?

1 Volt? I didn't think it was possible! How much in-game performance do you lose with these?

 

[amd64skater]

Look with these examples you guys have given is great. So things have gotten better over the years. I just don't need a iGPU. I have nothing against them I just don't know why I need one.

You know I was wondering if it could be Windows.

Yes I meant as a chip.

That's cool, but I mean, having an iGPU doesn't mean that you have to use it, or that you have less of anything else. If you switch it off, you still have a fully functional CPU like you do now.

 

[Beginner Macro Device]

Maybe the DP cable is broken

Most probably. Hot Chilean climate + overall cheapishness of mass production = failing cables ain't no unicorn.

Get something absolutely working then make decisions. It might also be caused by a faulty DP port. Try testing other DPs on your GPU if you haven't done it already.

Figured. Issue is that even a completely new install of Windows fails in the same way when the OOBE installs drivers.

I'm thinking the current DP cable is to blame, but I need to get an HDMI one to test.

 

[Beginner Macro Device]

Had the same issue btw. Fixed it by booting in the safe mode, removing OOBE drivers with DDU and installing 23.2.1 downloaded from the AMD website.

Try your luck doing that.

This makes more obvious what I paid for.

Nice question. And I already had the answer but I didn't think it was valuable to most. The results below.

FYI, the 2,6GHz profile has the VRAM at fast timings which helps in getting too close to the fastest of my profiles that the auto-uv profile is.

If they get an image in safe mode than the culprit should be obvious. It might also be some issue between whatever generic display driver is being installed by the OS in combination with the enhanced sync setting of the GPU driver if that's enabled by default.

Actually I only now realized you can see the OS selection screen - the GPU is perfectly fine and the cable as well.
This is 100% a driver+OS issue.

The issue is that this also happens if I DDU and install another AMD driver. The moment the driver installs, the screen flashes a static pattern and blacks out (and goes standby). This is in a completely new install too.

But while in safe mode change the display driver as well - not only the GPU one. Either switch to a Lenovo driver for your specific display, if it uses a generic one, or switch to generic, if Windows auto-installs a Lenovo driver.

I've seen people with 7900 with the same issues. I'd bet it's not a dying GPU.

Also try to install your OS without network - do everything manually.

 

[Kodehawa]

I managed to get everything working under Linux, so I realized that much, thankfully.

I'm still rather confused as to how this happened after I put my computer to sleep and woke it up, though.

Good idea

I tried another DP cable... it worked.

 

[KrazyT]

Damn, even simple cable can broke !
Glad you're returning in the game

My 2cts about iGPU : it saves my PC when my GC died during the pandemic (and where there wasn't any GC avaible or way too priced)
I even managed to play Diablo 3 (ok 1024x768 all LOW) ans Dorfromantik was doing better ...
Without it I couldn't use my PC at all, so glory to the iGPU

Still in the club!!

This 6700 XT seems just as power restricted with +15% as it does at stock.

I don't think the slider does anything.

Make it +12%, apply then +15%, apply. Driver bug moment.

I'll give that a try. Probably the more power tool also.

Additionally, I've seen these cards clocked at 2900mhz.

I don't seem to have an option for such a high frequency. Do you think it's from older drivers or people modding the bios?

It might depend on the exact model. On my Gigabyte the sliders go up to 2950mhz by default without any mods.
Also you have to measure your power draw - 6700XT has an absolute power limit of 203W, which should be what you see while benchmarking with the 15% added.
