Ok,
I managed to find myself a nice Opty 185 dual core to replace my single core 144.
I have had it a few days now and have had a bit of a play with it.
Stepping is CCBBE 0615 DPMW with the hardware in my sig.
Firstly I decided to find if I was stable at stock...managed 10 hours on Orthose blend test no problems.
I then wanted to find the max of the CPU.
So,... in the usual way, place the ram on a harsh divider [100MHz / 1/02] to remove it from the clock, changed the LDT/FSB to X2 then started to increase the FSB by 5 MHz and see if get Windows boot and Straight in for Super PI...take it from there.
I soon hit a bit of a wall on stock volts I could only manage 210 MHz into windows but this would fail Super PI
I increased the voltage slightly to 1.375V (stock 1.35v) and still the same, went to 1.40 V and no joy there.
I then remembered someone posting something about undervolting, so I dropped the voltage to 1.30v and I managed to get to 215 MHZ (2795.6 GHz) not a lot further than stock 2.6 GHz
This however wasn't stable in Orthoes
So, the question is am I missing something here ?
I am a novice when it comes to dual core OC'ing anyone shed a little light or part with some wisdom ?
