it's not really 1.72 volt needed for 4.4 Ghz.

Here's the situation :

- X38-DS5 vcore option above 1.6 volt increment from 0.0025 change to 0.05v (1.65, 1.7, 1.75, 1.8 etc)
- Vdroop on this mobo around 0.03, and real vcore detected by CPU-Z/Everest difference with BIOS setting around 0.03 too. Example : you set 1.65 volt in BIOS, the real vcore you get is : 1.65 - (0.03 + 0.03) = 1.59v
- When i need 1.68 volt for CPU, i can't set the vcore 1.7, because the real vcore applied will be 1.64. So i must go 1,75 volt on BIOS, get real vcore 1.72 and vdroop up to 1.68 - 1.69. This is the real vcore for the CPU.

About idle temp around 31 - 35 degree and full load reach 47 - 50 degree

nice clock benny~! btw while the penryn seems to be a very2 good ocing chip, i wonder why it seems like  clock per clock it has same performance as the current quad core..

maybe the extra l2 cache is too overkill .. currently...

if so, people who is not intends to oc extremely, might not have benefits migrating from kentsfield to penryn..

btw i hope the retail one also can hit as high as the ES.. or perhaps better than that!!

yap Q9450 best bang for buck... but there's a problem if you want to OC it...the multi is too low.. you will need very very good MB to reach higher clock with it.
