When you say the display turns off, did you mean the monitor turns off or the rig goes to sleep. They're two different things. If it's just you monitor shutting off and the system is still idle, then that's probably more to do with your rig.

It's hard to tell if you have the sandybridge offset idle lockups or not since you didn't fill out your rig specs.

Ah I see.. But hmm, the confusing part is, all of the above happens to me. My PC can freeze up from idle while on desktop, idle in lock screen or simple failing to wake from sleep.

And when I say the display turns off, I meant the Windows feature under Power Options to "Turn display off after.. XX minutes". I set it to turn off after 10 minutes.

How do I fill in my rig specs? Lol. But I have a 3570K which is Ivy Bridge. But anyway I've put in my specs on the first post but I'll paste it here again for convenience sake.


Specs:

i5 3570K (OC @ 4.5GHz 1.32V)
ASUS Z77-V
Sapphire 7970 OC 3GB
Intel 520 120GB
WD Caviar Black 1TB
Seasonic X 850W
Samsung SyncMaster 2032MW (1650x1050 Screen)
Windows 8 Pro x64


You have two different issues, sleep bug and just general stability with your cpu. You've got to fix your idle lockups by working out your overclock first. Then you look at the sleep bug, try different drivers or just disable sleep altogether which is the quickest work around.

Idle/sleep bug is same thing, i still have the same issue on my AMD rig wether it is oc'ed or not same as i did on intel one. Reducing his oc won't help (if i turn monitor off or sleep i get the same thing where in 1/3 it won't just wake up the screen)

They are two separate things. There are guides to fixing the idle bugs on Intels. You can easily bypass the sleep bug, ie. when the pc goes to sleep/suspend by not letting it sleep! Then if your rig is still locking up it's the freaking idle bug which has nothing to do with the sleep bug cuz your system isn't going to sleep.

Hmm are you running the latest VBIOS on your card? Sapphire tends to release updates without telling you and does some pretty significant fixes.

Looks to me it can't switch from the Board-off chip-off state which may hint at bad circuitry. I wonder if its possible to test another 7950 in your system to isolate the problem.

How do I check the VBIOS of my card? And how do I update it? And what does bad circuitry mean? Is it a hardware issue? Do I have to RMA it?


Also, I have an update to the current situation. I went into BIOS and disabled C3, C6 and Package C settings which were set to auto before. And for 2 days it haven't froze at all but just a few hours earlier it froze again. But when I went back into the BIOS after, I realized the settings were reset to default by itself. I didn't do anything. So maybe it was the BIOS changing it's settings back to defaults by itself that cause it to freeze again today? Well I'm still a little hopeful about disabling the C states being a fix for this issue. I'll update the results here if it fixes the issue or not, or if there are any more freezes.

So to answer your questions

BEFORE YOU READ BELOW:
Basically, if you don't want to flash the VBIOS and if it is more convenient to just go to the store and replace please go ahead and do that!.

If not, then look below - BIOS Flashing is a slightly tricky process and you can brick your card. You need to backup your BIOS before going ahead. If you do brick your card then you would need another one to use as the primary and then reflash the old one with the correct VBIOS you made a backup of. I am not responsible for breaking your card if anything goes wrong
If you don't want to go through this then please just return it.

1. How do I check the VBIOS of my card?
There is gpu-z: http://www.techpowerup.com/gpuz/
Check Sapphire page for BIOS: http://www.sapphiretech.com/presentation/downloads/download_index.aspx?psn=0006&lid=1

2. What does bad circuitry mean?
Sorry, I mean that one of the modules which is essentially responsible for waking the card from sleep mode may be screwed up so that *maybe* a hardware issue

3. Do I have to RMA it?
Most probably yes. If the BIOS update doesn't fix it then its definitely a hardware issue.

Look here to get atiflash on an external USB/CD

Thanks for taking the effort to help man. I looked thru Sapphire's website but I didn't find anything about VBIOS on my card. (Link: http://tinyurl.com/begq3nu)

Could it be that there's no update on the VBIOS since the initial release? Also, my card has dual BIOS. One that is set to 950MHz and the other 1000MHz. But I doubt switching to the other would help would it?
post #58 of 115
actually try switching it to the failsafe. Thats a good way to isolate if its a bios issue or a card component issue

I tried switching it to BIOS 1 last night and left it to sleep. The next morning, the same problem occurred. So is it safe to say it's a hardware issue?

Well, right now I've disabled C1E state in BIOS and testing if it helps.. But does anyone know the disadvantages of disabling C1E? I've read that disabling C3, C6 and C7 is fine but not C1E?

I have win7 -64, msi-AB is always on for 2x 7950, both set to 900MHz, (stock was 880 and 900, 900 is the primary gigabyte card), I've had this problem with 13.1 and 13.2.

Screen is set too shutoff after ~10 min, rig set to sleep after 30min I think, BUT THE RIG is AWAKE when this happens, because utorrent is running and I can hear the PC is AWAKE. I'm using DVI-D cable to DVI-D input on LCD monitor.

When it happens to me, the screen never comes back, the LCD monitor light says in the yellow standby, I have to reset.

I don't remember if this happened before I crossfired. At 1st I thought it was because I set both clocks to 880 (with the 900 gigabyte still the primary)


The 1 thing I'm sure of the last 3-4 times is that I (me personally )fell asleep watching youtube. This doesn't happen if just firefox is open, only when youtube was active with a video playing, and I'm sure the video finishes before the screen shut's off to idle.

Now I should open youtube play a something and set screen off to 1 min, drivers are my suspect.
