Just got info from my friends working at Intel as xxxxxx(cannot mention here)

It's true  L6XXAXXX is lower compare to L6XXBXXX in overclocking performances.But sadly this L6XXBXXX batch are only for export to mainly US market and europe recently.He said to me that all the proc are made in the same production weeks.Only at the last stage they will test the proc with some performances testing device before E-labeling into A or B type.Curenttly A type for local market or around south east asia.Since Intel is American company,they will give more priority to their end user compare to us.Also u can compare to their price+convert USD to RM..still their proc retail more expensive than Malaysian market price.

PS: I'm trying to get/buy E6600 L6XXBXXX batch from my friends working there but it so hard since staff purcase only can get ES version,but very cheap.. RM 400 only. .Hijack their warehouselah if dare..but be prepare cos more than 4 polis bantuan(not ordinary jaga) working in per shift with all their revolver & pump gun.Their security are more tight compare to local bank 

aiyarkk.. if onli i live in penang, sure everyday take minah kilang jalan2 cari makan 

btw, is the ES processor has unlocked multiplier same as x68series?

yep. me oso using DS3 rev C2 mobo
1.6v maybe too high to ur cpu or might hold by temp
