MBT completely locks up randomly in UI - possible ATI issue?

[brad_w 3]

beta drivers lasted about 20 minutes before crashing out. I can't see a way around this now. ffs. going to reinstall CCC as it clearly makes no difference, and then get a log file out of it and thoroughly look through. I'll post anything I find in it up here.

okay so after another day of research, on the series of cards in particular rather than the software they run; turns out the R9 series across the whole range, have had voltage/clock speed issues for awhile now that AMD haven't been able to fix with drivers.  quote from someone on another forum pretty much sums it up: "The main issue is how the card controls temps, voltages and clock speeds dynamically. Once the card gets hot, it starts throttling itself by dropping the voltage and clock speeds. Sometimes it does this too abruptly and then crashes or freezes the system."

 

I ran MBT in a window with MSI afterburner running along side just to check how the GPU reacts to different scenarios; it looks as though on idle my GPU clock will sit at around 300mhz, and Mem clock at 150mhz; when playing a video in MBT the GPU clock will increase to 450mhz and mem to 1400mhz; but when BROWSING MBT or during image transitions on the home screen etc, the GPU clock will kick up to 1150mhz, and my GPU temperature will actually raise 10 degrees just with MBT open and idle. I think the crashing may be caused by the R9 series dynamic adjustments issue - and MBT causing it to be so up and down every few seconds.

 

A workaround was to prevent dynamic voltages being sent to the card by installing Afterburner (with no CCC installed), and using this to control clock speeds, disable ultra low power state options, and enable 'force a constant voltage'.  it's been pretty dicey so far as i've had to sit here and work out gradually increment by increment what my 'sweet spot' is before it'll crash out on me; but with this last adjustment i've had MBT running a couple of hours, watched a movie, back to the UI, and had it open for a few more hours; with no issues so far.

 

what a pain.

Sounds like your definitely onto something there. Having to underclock your R9 though, what a pisser. Surely they would need to change the bios of the card though not the driver.

Not familiar with the msi tool but maybe u can set up profiles so for gaming you can have it on "normal". Keep at it .

Awesome, Brad.

I got to test that with my card.

Since you have reached it's an ATI problem and not MBT would be great if you could provoke ATI to fail outside MBT, I can not.

[MSL_DK 35]

Take a look at the GPU Core Clock while running MBT, compare with MBC. It's ridiculous!

 

EDIT: Also notice VDDC and memmory

hmm as this is a dedicated media pc I have nothing else on there to even begin testing with.. all i'm going on is other users experiences with games on other forums really.

 

I just applied the same logic to the media browser exe, gave it a go, and seems to be going okay..

 

but when running on the stock clock/mem speeds using MBC, I had no issues.. so unsure on that part.

yeah that's what i was mentioning earlier.. MBT i noticed crazy spikes.  everytime there's movement by me moving between folders, etc; or everytime there's a home screen tile transition animation, or screensaver animation.. my history shows it constantly spiking up and down during each transition.  i'm not saying it's 100% ATi's issue, it does look like MBT is causing the spikes. 

 

but our issue I think is the card cracking the sads over the fact it's overclocking and underclocking when going to idle, so often every few seconds..

 

whereas older cards had no issue, and nvidia cards seem to have no issue.  issues with both parties, mbt and ati i think.

Significantly for MBT

 

MBT could be great, BUT ... I do not spend another minute on it. Since July 2014 I have been looking forward to the hyped "new" version of MBT, they call it 'significant architectural re-write' Yes, I hope so!

So what can we do to get closer to the problem?

I have used MBC for 36hrs with out a single problem and no spikes.

Every time i switch to MBT it goes down the drain for me.

Im not a coder or anything so this might sound dumb, but whats the main difference in how MBC and MBT handle the movement and folder change?

I know its WMC in the background on MBC, but the problem wont go away by it self and what will happen when the next gen cards gets here? Still the same issue?

Theater now has the virtual scrolling feature for vertical lists:

That means the lists will no longer load your entire library contents all at once and will instead only load what you see at once. This will help make the entire app more responsive and improve navigation performance.
