Just mucking about with my new DS3 board and old 2.8ghz Pentium D chip... I don't have the option of changing the multipliers, it seems, but I was pretty pleased to find it ran up to 3.5ghz at 500mhz FSB and just 1.312V - stable for hours under Orthos, games fine, and doesn't get higher than mid 50s temperature wise- highest spike was 55, but it typcailly runs at 50-53 under Orthos torture testing. The Gigabyte Easy Tune utility wanted to hike the voltage past 1.4, which was causing a lot of heat buildup, but it does seem totally happy on the lower settings...
But, I'm no expert here... I wondered if running it so close to stock volts might be throttling it (ie, if I'd be better to be at a lower speed with higher volts)- the 3DMark scores were 1688 at 3.5, 1642 at 3.4, 1575 at 3.2, 1497 at 3ghz, and 1390 at 2.8... In other words, the increase between any 2 clocks drops every time it goes up. You'd expect this, of course, but I wonder if maybe the voltage or heat burdens are impacting this?
Also, I gather it's wise to keep the RAM and CPU bus speeds the same (or multiples of)- but I'm sure the RAM would clock a lot further, and I don't seem to have multiplier control over this chip. Might the speed benefits of clocking the RAM further offset the disadvantages?
I have to admit, I arrived at 3.5 purely because the 25% overclock, and the nice round FSB numbers appeal
