Stuttering in every game with a 7950? Hot temps on the CPU? Help needed

Bromhead · 17 Dec 2012 at 13:02

Hi guys,

So I experience a small amount of stutter in Far Cry 3 which I figured was normal. I've just installed Sleeping Dogs and experience the very same thing. It can be running at a smooth 60fps but then drop to around 30fps.

This is with vsync enabled and disabled, AA isn't on settings are on medium.

One thing I noticed though today, was my CPU temps were all running at 66 on all 6 cores. If you plus 10 to be safe this would be 76? Could this be the cause of stuttering I've been experiencing.

The GPU is running at a cool 39 or high 50 when stressed.

What do you guys think?

On idle the temps have stopped around 36/37. I guess I really need to buy an aftermarket cooler so I don't damage the CPU.

My main question though - Would this be the cause of the stuttering I've been experiencing and the slowness in certain tasks?

I will test that now and let you know shortly Bacon. As for the drivers they're the very latest ones installed.

CPU usage seems to be around 75% according to task manager. Might the CPU be the cause of the stuttering? Especially with it running so hot, I'm only running it at the stock 2.8ghz

Yeah I think I've just confirmed it. I booted up Sleeping Dogs again, running smooth as butter. As soon as temps hit 65/66 on the CPU it started showing stuttering.

Hmm, I'm not sure what I would be looking for in the events log covenant

Thanks - I was looking at the K2 Mount Doom. Main reason I haven't pulled the trigger, I'm just worried about size and it fitting.

I'm looking to upgrade to a Haswell i5 next year - would that cooler likely fit this and my build next year? More parts I can re-use the better

I can't link my current case as it isn't sold here and I think it's discontinued anyway

But I'm using an "Avenge Power Gangster Blue BOS-02A".

This was the PSU I purchased maybe last week from OcUK. After I upgraded to the 7950, the manual said 600w minimum, at the time I had a 500w Corsair CX, so I didn't want to risk it.

This is the PSU I'm using now.

Yeah - I have experienced stuttering since getting the 7950 - I really thought it was a graphics card issue or some setting I had overlooked. It never dawned on me to check the CPU temps since they've always been fine these past couple of years.

I guess the stock cooler isn't pulling it's weight anymore. Don't really want to try anymore games in case it is doing some serious damage to the CPU.

I guess I'll pick up the K2 Mount Doom and that should resolve the issues. Without Haswell being out I guess it's hard to know, but is there a cooler which is likely to fit my current 1055t, but also the Haswell i5 when it's out next year.

Bromhead · 17 Dec 2012 at 14:14

Yeah zak the PSU is mounted on the top of the case.

Bromhead · 17 Dec 2012 at 14:19

Ok thanks for the help guys

I'll start looking for an aftermarket cooler and fit it before playing anymore games

Thanks for those links! I'll swing by the OcUK store today or tomorrow and pick one up

Just to let you guys know what happened. I had to go for this cooler because of my tall RAM and using all four slots. Saying that.... I was extremely surprised how good it actually performed. I now sit on 21 idle with max temps of 55 under load. This was vs 37 idle and on 67 under load, so a really massive improvement.

Just for anyone else in the same position, this cooler doesn't block any of the RAM slots.
