According to posts on technical forums this problem became quite common for AMD 7900XT/XTX GPU users.
The issue: long initialisation time between power on and boot up BIOS screen. In my case it is up to 30-40 seconds. But in some cases it may take much longer.
I got Intel z690 platform and before 6800XT or 6900XT was working without such problem.
By the way, I'm using 7900 XTX Sapphire Nitro+ but as I can see, this issue affects different 7900 designs and from different partners.
I would really be happy, to hear some advanced ideas how to deal with it...
I had this problem after instalition of H220 windows update + drivers it was kinda anoyning my record was 10minutes. I fixed it in the most unpleasure way posible clear windows instalation then update and then adrenaline software. To be honnest its probably very specific issue.
With my 7900XTX on AMD B550 chipset there is no such "long initialisation time between power on and boot up BIOS screen.". It´s not noticeable... after few seconds after Power On Win11 starts. And "Quick start" in advanced energy options of Win11 is disabled!
Have you used CMOS clear after installing the new GPU?
Is the new GPU correctly connected with the PSU with 3 8-PIN PCIE cables belonging to the current PSU (no cheap y-adapters / no cables from other PSU)?
Do you use a riser cable?
Check in the UEFI of your Z690 Mainboard if there are "RAM memory training options" enabled? Maybe your RAM Timings are bad/ the RAM is not good... or maybe there is an UEFI Update available for you unknown mainboard.
And change PCI-E Express AUTO Option to manual/PCIE 4.0.
Unfortunately, this is more complicated problem than that.
A would like to admit that BIOS settings/FLASHING different versions/proper installation and other simple things was done.
Also, any other card 6800 6900, 3060, 3070 starts fine.
Hello! I registered to the community to add that I also encounter this problem. I have a brand new rig with a Gigabyte 7900xtx Gaming OC, on an MSI Z790 Edge Wifi and the boot time before I reach the Windows login is 36 seconds or more, cold boot. If I restart is far far worse.
It's definitely a GPU issue, as the EZ Debug led stays white for most of the duration and only when it turns off, it starts loading Windows.
In addition, when I removed the 7900xtx and switched to the integrated intel one, the loading time was cut to about 15 seconds (Bios boot time from Windows Task Manager).
This is reported in other fora:
PC takes longer to boot with new gpu (7900 xtx), white vga led stays on for 30 seconds before bootin...
Question - AMD 7900 xt causing boot times to be INSANELY slow. | Tom's Hardware Forum (tomshardware....
Till now, no solution has been found. BIOS is latest, driver is latest, although this is before Windows boot, so irrelevant. Any help or insight is appreciated.
I am experiencing exactly the same issue with long post time when I have my Powercolor RX 7900 XTX connected. Ez debug stays white for as long as 20-30s (or so).
This issue doesn't exist when I remove the card and use intel integrated igpu.
Is there something we can do to speed up this post process?
Hello.Same problem. Gigabyte rx 7900 xt gaming oc and gigabyte z690 ud ddr5. On 3080 and uhd 770 it takes 8 seconds to load bios. After installing the new 7900 graphics card, the boot time was 30 seconds. Before booting the system there is a long initialization of the GPU
Upd. "CSM support - enable" - This helped me.
So I quite sure this issue exists using Intel Z6xx, Z7xx platform + 7900 series gpu. And it is definitely combability problem.
Is any support members appears on this forum? Or maybe someone have an idea how to pass this problem to AMD GPU support team?
Hello Guys, first sorry for my writing. I from Brazil.
I tested the rx 7900 xtx in a 11 Intel processor and a mobo from msi (boot in 8 Seconds). And no have issues with boot time, but in z690 and 13 Intel still have a long post about 50 Seconds or more delay.
I believe it is a problem with the intel and socket of the 12th and 13th generation. not with the rx 7900 xtx.
Do you guys have the latest BIOS and ME firmware updates? I'm waiting for my 7900XT from XFX, and I'd hate to see very long boot times with it, the 6950 XT was fine. If the card is good, it probably won't be a dealbreaker, as I try to use sleep usually, but I actually had some issues with sleep with the 6950 XT, so it's still a gamble for me.
(the 6950 XT was very nice for the price, but I managed to order a 7900 XT for only $88 more, so it seemed like a no-brainer. I just really hope it works out)
Got my 7900 XT from XFX, and yes, it takes a bit longer to initialize before the BIOS splash screen appears. Only about 12 seconds for me, vs probably 3-4 seconds with another GPU, so the entire boot sequence is still acceptable (still faster than any MSI board I've used in the last few years).
My mobo is Asus Z690 TUF Gaming Plus D4
For people using the MSI Z790 EDGE WIFI and a 7900XTX Merc from XFX, at least in my case.
The solution to the long posting, which is either a GPU or Motherboard bios issue, relies with UEFI boot. If you disable UEFI boot, the motherboard boots as normal within the average much faster load times. UEFI boot takes 45s on average to POST with this GPU. I don't know if this in an AMD or MSI issue. However this is what I found to be the temporary fix.
Multiple bios have been released for the board and I have this since December last year.
Also, if you remove the PSU cables from the GPU, but leaving it on the pcie socket anyway, will turn off the GPU and allow the motherboard to boot instantly with the iGPU from intel in UEFI.
This proving to not be a ''poorly socketed GPU issue'', or a ''PSU cable extender'' issue, or any user error whatsoever. I have read a lot of excuses or reasons for this problem to occur, but I have come to the conclusion it is, definitely, a GPU or MOBO issue.
Also running in CSM disables Re-bar, so AMD please fix this.
Hope this helps
Have the same issue with my PowerColor 7900XT and Gigabyte Z690 Gaming X. Adds 30 seconds to post. I've seen multiple motherboard bios updates since I've purchased the card. I've never seen a emergency patch GPU bios update from a manufacturer in my lifetime. Has anyone? I don't think this is getting fixed.
I don't want to sound negative, but I also don't think this is something that's ever going to be fixed, at least not fully. IMO, if they could, they would have by now. The same with high power draw on idle with multiple monitors. I read reddit threads that are 4 months old, where people kept optimistically claiming this is no big deal and AMD will get it addressed with a driver update in "a couple of weeks", and now, 4 months later, the issue is still there. I have a feeling it's just how those cards are.
One of the bios updates I installed, exhibited a fix for certain Nvidia cards not posting. I was hopeful that the problem was related and might be addressed in that release. It was not.
check you have memory context retraining on or off ( on for fast boots), I had an issue with the wrong ram ( even though it said it was EXPo compatible) swapped to the QVL memory modules ( only 2) and I have had no issues since.. I have the same cpu and a tuff 670e mobo. boots in on average 10 secs give or take a couple milli secs.. but its been very fast.
I also have the power colour red devil xtx..
I have the same issue, long initialisation time (45 seconds) between power on and boot up BIOS screen with 7900XTX.
No such problem with my GTX 1080, it was very fast from cold start to bios boot up screen (and to windows login).
I have the latest BIOS and have tried to switch from UEFI to CSM, disable/enable fast boot and MSI fast boot, disable "above 4 gb ...something.. crypto mining (what is this??) and alot of other settings - no difference.
MSI Pro Z690-A Wifi DDR4, latest bios version: (7D25v1B)
Powercolor Hellhound 7900XTX
From AMD Adrenaline:
Driverversion for AMD Windows
PSU: Seasonic Prime PX 1000, 1000W
Powercolor states on their homepage that they do not provide any bios-files (or updates?) due to voiding warranty if BIOS is changed.
If anyone can help I really appreciate it.
Hi! I have had the same problem and wrote about it as a reply in this thread.
For info, I did two things and now the boot initialization time is down to 20 seconds until BIOS-text apperas (before 45 seconds).
No 1: I installed a new update to AMD Adrenaline, version 25.3.2.
No 2: I entered my BIOS and selected to load the "Default settings", then selected to "Save and reboot".
After this the improvement from 45 seconds to 20 seconds was there.
(I then adjusted my bios settings regarding fan curve, selecting XMP for MB RAM, no MSI-logo while booting and left other things unchanged.)
I hope these two steps can help other with the same problem.
Please let me know.
I have a Sapphire 7900xtx Nitro with an MSI x570S Tomahawk Max Wifi and luckily I do do not have the long load times . Load times are basicly normal and quick , and I do use 3 ultrawide screens ~ The only issue thus far with my change to the xtx is SAM (rebar) is not recognised by the AMD app even though its turned on in the bios .
Hello sir, basically I had the same problem with my 7900xtx and found the solution.
So what you need to do is to have 3 separate cables from your PSU to your GPU. Because 1 cable can provide only 150w and 7900xtx goes over 400w normally.
You can thank me later
