There's a half confirmed rumor on the web that intel is about to supply its partners and distributors with a new batch of Core i7 920 processors and Nehalem based Xeons, that have their stepping updated from the current C-0 to D-0. Ready to ship on March 2nd, the new stepping will feature:
- New S-spec (from SLBCH to SLBEJ) and Material Master numbers for the converting products.
- CPUID will change from 0x000106A4 to 0x000106A5.
- The electrical, mechanical and thermal specifications remain within the current specifications. Intel anticipates no changes to customer platforms designed to previous Intel guidelines.
- Readable serial number will be removed from the package ink swatch to fully mitigate the potential risk of the IHS cosmetically overlapping a marked serial number. There is no change to the ULT matrix content which continues to contain the serial number.
It's said that the motherboard BIOS update will be required to identify the new stepping CPUs properly.
