Almost 50% Overclock, Pentium D 915, On Air!
Swapped out the D 820 furnace in System 1 today for a new Pentium D 915 (65nm, 2.8GHz, 800MHz FSB, 2 X 2MB Cache)
46% overclock: Mulitplier 14 X 293MHz FSB = 4102MHz. That's 1300MHz above the stock frequency. I had heard these CPUs were very good, the last steppings in the D series dual core from Intel. Oh yes, running about 4*C cooler and .5v lower vCore clock for clock than the D 820 that came out of this machine.
OK, here are settings and readings:
Multiplier: 14 (locked)
FSB: 293MHz
Bus: 1172MHz
vCore Set/Indicated: 1.362v/1.31v (default set is 1.3)
Northbridge: .2v over default
Southbridge: .1v over default
FSB Termination: .1v over default
DRAM: DDR2 667@732
The machine is running stable so far under full load of two instances of Folding@Home and light multitasking. I believe there is headroom still available.
CPU Z identifies the CPU as a Pentium D 920. The D915 actually is the same core (x2) but with virtualization technology absent.
I had it full load earlier today at 4.2GHz, 1.375v vCore (set), but it crashed during multitasking)

umm dont think i missed anything.
ill let u know how it goes in about 2 weeks.
I should also state that I've never overclocked a Conroe system. I don't know what if any voltage boosts circulate through the northbridge and MOSFETs. From what I've been reading, Conroe CPUs require far less voltage boost for overclocking than earlier series Intel dual core CPUs.
You will definitely have fun with your 915/P5LD2 combo. That CPU was born to be overclocked. When you start working up the overclock, watch the vCore voltages. What you set in the BIOS and what you get from the PSU may very well be two different things. The P5LD2 and P5WD2 both suffer from "vDroop", that is the falling of CPU core voltages under high load/overclocking. You can compensate for it, just realize vCore will drop from what you set in the BIOS.
