Performance drop after a power cut

Greetings everyone,

I am a proud owner of the following system:

Alienware M17x-R2: i7-940XM | 1920x1200 RGB LED | ATi 5870m Crossfire | 4 GB DDR 3 1333mhz |

I am currently using a 32" TV as a secondary (extended) display.

This morning, while I was playing a game, the electricity for my hole house went off, so the laptop flashed a few times (as the TV power supply was cut).

For some reason, I am now experiencing a huge performance drop in all areas. I have all the drivers / bios up to date but I can feel that something is wrong.

I just did a 3dmark test and system dropped to 11k (It was 20k yesterday). I am getting very low fps in the games (averaging 20fps in sc2, 50+ before).

The system is not in stealth mode, and I tried unplugging the TV and just run with the LCD with no luck.

Any suggestion?

Thanks in advance.

 

Have you tried the power drain yet?

Turn off the laptop, and unplug the AC adapter. Flip it over and remove the battery. Next, hold the power button for around 30 seconds. Reinsert the battery, AC adapter and switch it back on.

Access the BIOS and check to see whether it is running with 240V. The last time I had a power cut, it dropped to 177V iirc.

Next thing to try is a power drain remove battery then hold down power button for 30 seconds then put battery back in place .If that don't work open service panel and disconnect the CMOS battery for a min then plug in .

You beat me to it

 

Heh. xP ~

 

Hello,

Thanks for the quick replies.

I tried unplugging the battery with no luck. I can try disconnecting the CMOS battery for a minute to see if that helps.

on Hwinfo32 everything looks okay, except for one of the GPUs

GPU #0: Clock 300 Memory 400
GPU #1: Clock 100 Memory 150

Is there any way to alter this?

 

Worth a try with the cmos.You can try AMD Clock tool to set back to 2d clock i dont have 5870's but i use this if clocks stuck on 3d.Worth a go.

AMD GPU Clock Tool v0.9.8 download from Guru3D.com

 

Press the stealth mode button.

 

Stealth mode is not active.

I tried going on stealth and then full power, with no change.

 

Worse comes to worse try reinstalling your GPU driver Chiefs.

Cheers.

 

Hey,

Thanks all so far.

After reinstalling the GPU drivers again, the clocks are back to normal. However the bad performance overall remains.

I am going to try reinstalling every single driver in the system, see if that helps.

 

Hey all again,

What should be my normal GPU / memory clock for every single 5870m?

 

Chiefs what actually does that mean ?.In fact i dont want to know

 

700 Mhz Core Clock and 1000 Mhz Memory while under load

100 Mhz core clock and 150 MEMORY while idle

 

Thank you.

If I manually set the clocks to 700/100 the performance is back. However I am not sure if it is a good idea to keep the card at maximum speed forever..

This is only happening with the first card. The second GPU is idleing 100/150 and clocking up to 700/1000 when used.

I tried reinstalling driver with no luck. The 'new' drivers put the card to 405/1000 by default but it is not moving from there.

Not sure what else I could try.

 

Just throwing this out there, but did you check the CatalystControlCenter, mine has a bad habbit of disabling crossfire if it drops to battery even for a few seconds.

 

Hey all,

Looks like it was a driver issue. I rolled back to a previous windows instance, and everything is back to normal now.

Thanks all.

 

Thats great to know man have fun with your machine

 

Depending on which video drivers you're using, you may find that CrossfireX had been disabled. I found that the Dell official drivers had this fault - lose AC power, and CFX is disabled permanently. You have to manually go and re-enabled it.

The latest AMD/ATI drivers seem to have fixed this issue. CFX is disabled when on battery, but re-enabled when back on AC.

 

I've had this problem in the past. Glad to hear you got yours fixed by rolling back.
For me I had to roll forward (get the newest vbios and drivers) and downlooad CAP and the profiles.
