depends on steppings

144 is 3000+
146 is 3200+
148 is 3500+

multiplier wise.. but with the extra cache

if you can afford 148 of course.. with the extra multiplier.. if not the 146 will be nice..

144 will need high HTT to clock it high

OT: dude, if u think ya winnie is obsolete then mebe half of us here can throw away our rig ledi... 

even down here in sgp they have limited unit only for d opty... 

where did u bought the opty n how much..jaz the proc only or with the mobo as well?

bro,

are u using divider? which bios you use? 

rlhc17, you are using BH5 right? at what voltage? and did you guys know that for every increment of VDIMM it's advisable that you increase the VCORE as well. Particularly the E revision of the core. For like 3.0v VDIMM applied, it's a common practise to up vcore a bit to let's say 1.5v. This is not to ensure stability mind you, it's to ensure the safety of your processor so it will not suddenly becomes unusable. So this is very important, this is not targeted at anyone, this is just a reminder because I have seen most members here especially the newbies have no concern over this matter.
