Need some help with 7950 Overclocking(Crashing with Dual Monitors only)

post #1 of 13
Thread Starter 
Hello. I just got a Sapphire HD Radeon 7950 Boost with 925MHz GPU clock and 1250MHz memory clock at stock(http://www.amazon.com/gp/product/B0098HW1HG/ref=oh_details_o00_s00_i01?ie=UTF8&psc=1), that is what AMD CCC says anyway. I've been trying to OC it further and I have been having a weird issue . I OC it to 1100/1350 and it goes through benchmarks like the Heaven benchmark and 3dmark11 without any problems, I also ran in game benchmarks like GTA4,resident Evil 5 and Sleeping dogs and runs great. The problem that arises is when ever I open a video file and play it in windows media player it will crash my video card. I have dual monitors and on my main monitor it shows a crash/artifacts here is a picture of what I mean:


This only happens when I change the memory clock tested only changing the gpu clock and no crashes with it.The temperatures are fine highest it got was 75C with heaven benchmark.

On my other monitor (Sorry should of taken a pic of both in the image)it doesn't show that image, the other monitor is extended and not the same image on both if any one is wondering. Eventually if I wait long enough on my other monitor it will BSOD 0x00000116

Also when I lower the memory below 1350 and above the default 1250 it wont crash when I open the video but it will flash/flicker on the bottom half of the second monitor , this also happens when I skip the video ahead or rewind it. This will also happen sometimes when I watch a video on YouTube. I have set the power control setting to +20% and used CCC,afterburner and trixx to try and OC it.

I have the latest beta drivers and Catalyst Version 13.2

Am I doing something wrong or is it the card because it doesn't matter anything higher than 1250 will cause a problem outside gaming/benchmarking have yet to crash during those but watching videos gives me problems.

it looks like a driver issue. Could you roll back to a previous driver (12.11 or 13.1) and check for stability. Also, use either of the one sofware to overclock. Either go Ab or Trixx.

Thanks for the reply. I rolled back to 13.1 and the same issue. This time I tried opening the video file first and it flickers my monitor still but didn't crash. I then did a benchmark on heaven and went through it fine. Then I went back to open the video and it crashed. This was on 1100/1350. I should also mention every time I hit apply after changing the memory clock the screen flickers.

EDIT: Did some benchmarks with 1150/1400 and passed heaven benchmark. I then did 3dmark11 and got these scores:
Performance: P8604 with Graphic Score 10056 ,physics 5950, combined 6086
Extreme: X3211 with Graphic Score 2975, physics 5970, combined 3890.

Opened a video file, crashed. confused.gif

An update

I decided to try another pcie slot and it doesn't seem to crash when I open the video file, but it still flickers the monitor, my secondary one, whenever I hit apply on sapphire trixx as well as skipping the video.
I will keep opening the file through the day and see if its stable and run some benchmarks some more.

Every card will do that when you hit apply.

Oh ok, thanks

But new update As I mentioned it didn't crash when I opened the video file first. I then went and did a heaven benchmark and passed it and then right after the benchmark I went to open a video file and it crashed with the image above.

EDIT: So I unplugged my secondary monitor and the flickering disappeared when I click apply and skipping in a video.(Flickering happened on my secondary monitor only)
I then ran heaven benchmark, passed it and went to open a video file and it didn't crash. Tried it multiple times and seems to be stable. So does that mean somehow my secondary monitor is causing this crash on my main monitor because only my main monitor show the artifact as you can see on the picture I posted.

Hey, was searching the internet for a solution to a different problem I had with a 7950, and came across this thread.


I had the same exact issue as this, and I managed to solve it!



I'm using an ASRock MOBO atm and there was a setting in the BIOS, now forgive me for not remembering off-hand what it was, but I disabled it and that problem disappeared completely. I've been running this setup for two weeks since then and have not encountered the problem since, whereas before it happened quite often.


I'll go goof around in my BIOS to see if I can find the setting for you, but for now. That's what you need to do.


EDIT:
I looked, and I can't say for sure which setting it was. But i'm almost positive it was a IGPU Multi-Monitor setting. It was set to enabled by default, once I switched it to Disabled, the problem went away. So look around in your bios, the setting was in my North Bridge configuration.

Thanks for your input, but I have a ASUS P7P55D-E Pro motherboard and don't see anything in the bios relating to multi monitor settings.
EDIT: I tried my secondary monitor only and it works fine. So this crash only happens when I have both monitors connected and when I try to open/watch a video. The flicker is only there when both monitors are connected as well.

Take another look, and search for an iGPU feature/setting.

I'm sure your motherboard supports it. It's a setting used for that lucid virtu program.

Nope, don't see anything relating to it. I dont know what else to try the problem happens only when overclocked, works fine on stock and it also worked fine with my old video card, a gtx 460.
