I have the gigabyte 6900 xt reference card. On every cold boot my motherboard will give me a long beep and 3 short beeps, indicating an issue with the card. However if i manually wake the monitor by pressing the on button on the monitor and then turn on the pc it will boot up as normal.
I can always tell that the pc will not boot as the stand by light on the monitor usually flashes when the pc is off, however it is solid after the pc has been turned off for a long period.
Restarting also boots fine and even if i shut down and leave it for an hour it will boot up fine.
I previously had the vega 64 in this setup which I had no issues just to rule out other hardware.
GPU: 6900 XT
PSU: Corsair 1000W
Motherboard: Gigabyte 570x Pro
RAM: Corsair 32GB 3600mhz
Any ideas? let me know if you need any more information, I'm puzzled.
ok, so I researched it a bit, and my Corsair RM850X PSU is apparently single rail.
nonetheless I have move around the connectors a bit and will now test things out. I fail to see how that would change anything though... 12 V is 12V , especially on a single rail
It has to do with electrical stability on cards pulling or rated to pull 200W or more. So by running 2 separate PCIe 8 pin power lines on your RX 6800 XT you're exceeding what 1 cable can handle by 64.2W at full load (362.4W). Technically one cable can handle up to 300W. Also each cable is only rated for 9A and at full load you could use about 14 A. You'd need to use a PCAT to measure your card to see what I mean. Power draw is mostly FPS dependent and single vs. multiple rail isn't the reason for using 2 power cables. It's the amount of power one cable can carry which is ~300W. So if your card spikes or you start pushing say 400 FPS at 2.5W per FPS or so, wiring becomes everything. The card doesn't maintain this high draw for long periods or there would be some seriously bad things happening.
With the cold boot thing, brand might play a part. Disabling C-states and sleep and/or switching to a "high performance" power plan in the OS might help. If you just installed the newest driver, may be the 12.2.1 was better?
Well, Changing positions on the PSU didn't really change anything for me... Also, when I game at full load (290W) the system is stable, etc...
for the record, I've been having this cold boot issue since I got the RX 6800 XT. And I've tried every driver from amd.com that got released.
Installed the latest one today, as well as chipset drivers that got updated on Feb 4...
I'm at a loss. for now I'm just pushing my monitor button before I start up my PC. Really seems to be some deep sleep state of the LG monitor, making it take longer to wake up when using Display port.. Still very short, but not short enough for this specific GPU I guess
Using HDMI seems to not exhibit this behaviour, but it also limits the refresh rate to 100 Hz @2k resolution
I also have an LG34GK450F and I see the same behavior. When I manually wake the screen it posts the first time the windows login screen. later warm no issues. before activating bar also no issue.
If there's a monitor driver for your monitor's try installing it. This could be a power setting too like if you run an SSD, make sure it's set to never turn off. SSD's have firmware that lowers the power for sleep states if you use those. If you don't, turn off all the "C" states in BIOS, cool n quiet too. Run a high performance power plan and make sure the SSD is set to never stop. Spin drives can power down when idle not SSD's, it's bad news.
Installing the drivers did not work.
Meanwhile I found other reports of people with Big Navi getting this error when having only a Displayport cable attached to the graficscard and SAM enabled.
That shouldn't matter. If you have a 5000 series CPU, then SAM should work with the GPU. It only works with certain games anyway, so it's not on all the time, just enabled. Try another monitor. For whatever reason one said they had to power cycle the monitor and it would work. When I shutdown my PC, I also power the monitor off and when the PC is on, my display is set to not sleep, so I never run into this issue. If I would want my screen off for some reason, I'd simply power it off.
I'm on the same boat, but i test the 6900xt on 4 different systems with different specs.
All Run smooth and perfect with 3070, after i install the 6900xt the system boot all led and fun spin but i got no-signal and on mother board i got a Ez-VGA led error, i tried everythink possibile solutions:
After all these checks, i move to my other rig
Same results, no signal i take my system to a friend of mine who as an ENERMAX 1200w with the following system spec:
I think my 6900xt is a DOA, i opened a ticket to AMD and wait for a resposne, figer crossed.
Your card is not DOA, its fine.
I have used R9270X, Reference 5700xt and Sapphire Pulse 5700xt and also Gtx 1070ti, RTX 2080 super and now rtx 3060ti.
The simple fact is I have always faced many such problems as sleep wake issue, system freezes, driver crashes, game crashes on AMD cards. I have never faced any issue even once with Nvidia cards. AMD ppl will make you go round and round in circles by saying its a ram issue, a monitor issue, psu, windows etc etc
Its100% a driver INCOMPETENCE issue with AMD. With Nvidia, I hate to say but it just works.
I got the same problem with my $2000.00 six-month-old Saphhire 6900XT. I contacted www.sapphiretech.com, and they don't want to hear about it and told me to go back to who I purchased...
But anyway, I have a vintage Nvidia GeForce GT 620 in one of the slots. I unplug the display cable from the Sapphire and stick it into the GT 620 and see that the Windows is already booted. In my Aorus Xtreme X570, I unplug the GT and plug back into the 6900 and get nada.
This happen about a month ago on a brand new Asus ROG Crosshair VIII, (for which I got a refund from Amazon because Asus RMA'd it for a RAM issue, Corsair concurred) when the Sapphire would not post. After about 10 reinsertions it started working again, but this time a month later in my old X570 Aorus Xtreme. the card has all the pretty lights but won't post. I hadn't got around to selling my old Aorus Xtreme Ge Force 2080 Super, it works fine, so I'm ok for now.
