Re: Intel Core 2 Extreme X6800 B2 + P5B Deluxe

Slowly finding the balls to be a bit more adventurous and decided to do the Asus P5B Deluxe vdroop pencil mod I used a 2B pencil and about 4 strokes across resistor pictured with yellow line through it below:



------------------------------------------------------------------------------------
Before vdroop pencil mod
- resistance was DMM measured at 80 ohm
- 1.325v bios set vcore = 1.280-1.288v bios monitored, 1.29v idle/1.27v load Asus PC Probe2 reported.

------------------------------------------------------------------------------------
After vdroop pencil mod
- resistance was DMM measured at 37.4 ohm
- 1.325v bios set vcore = 1.296v steady bios monitored, 1.30v idle/1.30v load Asus PC Probe2 reported.

I'm happy with that for now a reduction in vdroop by ~0.03v Asus PC Probe2 reported under load. Not going to be too greedy

Before vdroop pencil mod @1.325v bios set
CPU Prime95 v25.1v small ffts load:

3600Mhz use to take 1.45v (1.38v Asus PC Probe2 loaded), now with vdroop pencil mod 1.4125v (1.38v Asus PC Probe2 loaded)



3807mhz at 1.5875v bios (1.56v idle/1.552v load)

Idle


Load


Going very nicely so far 3hrs 20+ minutes prime95 small ffts @3807Mhz at 1.552v! Was around 57-59C load temp at under 3hr mark, past 3hr mark seems to have jumped to 60-65C - very different from my E6600 B1 where even after 4-8+ hrs temps only rise 2-3C.



Decided to stop it at the 4hr mark
