Hi guys
I have a very strange problem.
When i play games i get bad stutters so iv been switching parts from my other pc and a fresh install of windows 7 to see if this would work. Different motherboard but same make and model as in my sig etc etc for the parts, exactly the same as in my sig but from my other system.
Now when i do a a prime95 test while gaming, my games run smooth, without prime95 my games go stuttery. What would cause this to happen and is there a way i can get my CPU to run full throttle 24/7 or would this be bad for it ?
Many thanks.
I haven't used a newer Intel mobo, nor an older 775 one for a while but, it was the EIST or something like that setting, and speedstep that usually you want to disable to prevent it downclocking.
Secondly I'd try running a game with gpu-z/msi afterburner in the background checking gpu clocks, check nothing is downclocking gpu wise.
Always helpful if you have a second screen then you can leave stuff like that open to check on as/when needed. I can't think of anything off the top of my head that logs cpu speed so you can check how often its downclocking, I just use cpu-z on the other screen so can see it actually happen.
Stuttering though could be down to so many different things, what game is it in, what gpu overclock if any, gddr5 auto downclocks if it finds its unstable, so theres potential that internally it can downclock WITHOUT showing externally if its unstable.
In some games vsync just does not play ball with the engine at all and produces a horrible stuttery performance, both Nvidia/AMD suffer from this in various games.
For me a 5850 can provide 60fps rock solid standing still with vsync on in Just Cause 2, but turn and it stutters, drops to 20-30fps, then after standing still or just not turning the fps gets back up to 60fps after a few seconds.
Now turn off vsync and all the same settings the 5850 blasts along well above 100fps and DOESN'T drop when turning, at all, buttery smooth doing anything. Vysnc just introduces horrible horrible stuttering from no where, don't know why but it does, GTA4 tends to be less good with vsync on, with Nvidia users seeing it aswell in that game.
It could be loads of different things and hopefully its not anything that Sandybridge/intel have changed that makes games have issues, though Steam doing an update just for it, and various other Sandybridge issues are starting to make me think otherwise.
