RX 480 Hybrid sleep mode issues.

Jump to solution

my XfX RX 480 8gb will not wake up from sleep if hybrid sleep mode is turned on in the power settings, I've checked with a friend that has the same card, and his card also doesn't wake from hybrid sleep.

Is this a driver issue?

win 10 Pro N

intel Core i5-4690k

I was also not using adapters, HDMI 2.0 and Displayport 1.2 plugged in directly and hybrid sleep is working fine as I previously reported.  So it must only be passive adapters where the issue occurs and only when using 2 monitors it seems.

The only adapter I have here is a Club HDMI 2.0 to DP 1.2 and I can use Hybrid sleep with that but that is an active adapter.

Please report the issue here: Giving the make and models of display, the make of adapters (if known)

I had a problem with my RX 480 that wouldn't let me wake it up from sleep. Disabling hybrid sleep fixed the problem, but unplugging my second display fixed it as well. With only one display, the RX 480 could use hybrid sleep just fine. With Two displays, the RX 480 needed hybrid sleep to be disabled. What could cause such strange behavior is beyond me, though it is probably a driver issue, I assume.

Hmm, me and my friend also have 2 monitors, quick question are you using a passive adapter for the second monitor? I have a sneaking suspicion that might be the thing thats causing issue for me. I picked one of these up because my other monitor has no displayport: https://www.amazon.co.uk/MutecPower-Displayport-Video-Adapter-Converter/dp/B0191XW1SU/ref=sr_1_12?s=...  and when I unplug that adapter, my computer wakes from sleep just fine.

I was using two DisplayPort to HDMI adapters, one for each monitor. I believe they're passive adapters, but I'm not completely sure. It's this: Amazon.com: DP to HDMI, Rankie 6FT Gold Plated DisplayPort to HDMI HDTV Cable (Black) - R1102: Home ... , if that helps.

I am having the same issue with a similar setup. Dual monitors, 1 hooked to HDMI, the other to a passive DP to HDMI adapter. Once the monitors go to sleep, they will not come back on. I've had this card for a week, and it seems to have started today ever since I touched Wattman. I'm not sure my situation is exactly the same, but I turned off Hybrid Sleep to see if it resolves the issue.

Did others notice this behavior after using Wattman for the first time?

Edit: Disabled PCI-E Power saving mode and Hybrid sleep and the problem doesn't occur any more. Will test with the individual settings tonight and see what ultimately fixes the problem.

I have dual monitors, and Dual RX480s. Main  display running on display port, the secondary monitor running on HDMI.....  No adapters of any kind and I do not have this problem.  Must be the passive adapters.

Here's another interesting thing: I returned my RX 480 that had this problem, and I decided to spend the little extra and get a GTX 1060 instead. Now, when my computer wakes from sleep, the Nvidia driver causes the system to restart with a blue screen error. Using HDMI and DVI connections for my monitors with no adapter, it still happens. Disabling hybrid sleep, it still happens.

I have no idea what could be the cause here, but according to this thread, it may have something to do with the BIOSes being incompatible. I find it very peculiar that both my RX 480 and my GTX 1060 had problems with sleep. They're different problems, granted, but this does point to some kind of incompatibility between my motherboard and the BIOSes of the newer video cards.

For reference, the card I had before was a Radeon HD 7950, and it would always wake from sleep just fine. Before that I had a Radeon HD 5770, and it also worked fine with this motherboard. My motherboard is a Gigabyte GA-870A-UD3, and I run an overclocked Phenom II x4 955 if that helps with anything.
