Cider old chap, please set her to 500/900

That is safe and probably as good as your VDU can handle.

Now, I built this bit of crap about 4 years ago............ a P4 2.26Ghz was the best around......so I decided to build a "racer"............we are talking about 40,000 Rands here...............

I got her to run stable at 3.066Ghz...............I had cracked the 3.0 barrier

She now runs at normal 2.26................
