I just purchased a P4/1.8MHz 512KB L2 cache, Northwood. And a socket 478 mobo: MSI 645 Ultra, together with a PC2700 512MB RAM chip. It turned out something was wrong - i couldn't get past the logo of the boot screen, and was not able to initiate the BIOS screen.
Got another RAM chip to test with - same error. The shop (komplett.no, Oslo) asked me to return the whole mainboard WITH CPU and RAM. Which i did. They then found the same as I: It didn't boot. So I got my money back for the mainboard, a bag with the pieces for the boxed CPU, and the RAM.
I noticed that they had given me a 64MB PC2100 RAM chip, which they immediately replaced with the correct type, the 512MB PC2700 chip. But - and here comes the interesting part: As i unpacked the CPU, i noticed that the surface was very much "matter" than it used to be, the corners were rounder, AND: There was a tiny hole in one of the corners that i hadn't noticed before.
Actually... when i installed the original CPU, i remember I wondered about which way to insert it - and i did NOT notice any hole, which would have been a very clear hint of course.
Am i remembering totally wrong here? Or am i right? Are there P4/1.8A 512 L2chips made without that "corner" hole on top?
