Minecraft troubles.

So, if I play minecraft without doing anything, it runs at super speed as if I was using some kind of speed hack, when in reality java is just being spread across multiple cores and for whatever reason it doesn't like that on AMD cores.

If I limit java's affinity to core0 (or any core really) It runs fine, BUT IT DC's ME EVERY 30 SECONDS!!!!!!!!!!

If I let it run on all cores its fine but it runs at super fast, but also places like 4 blocks down and destroys 4 blocks and everything all at once...

Anyone know how to fix this?

Edit: With the processors unlocked, spreading it across multiple cores, it still dc's me, but less frequently.

It's because you overclocked your CPU. Minecraft's speed is dictated by your CPU clock speed. Overclocking isn't something Windows or Java can see if your using or not, so its running like normal. I overcame this on an Intel CPU, I have no idea how to do it on an AMD one as the architecture is completely different.

I'd put your cpu back at normal, then run on all cores, it will still run far better, and cooler, than trying to use an incorrectly overclocked AMD.

My minecraft used to do this back in the age of classic and still does it sometimes. Hell, Skyrim and BC does it as well.

Acutally the connection issue has been resolved, and I did return the clock to normal but it did it anyway. So yeah. Oh well lol. My connection isn't an issue anymore and I still get like... 30-60 fps on one core so lol.
