At work we received from a vendor, as they told us, a quad quad-core (16 cores total) to test our applications So we start installing it with RHEL4. And we only saw 8 cores... so we start mailing to the vendor with screenshots... and one of the screenshots was of the boot-session... it was telling us that we have 4 Intel dual-core Xeon MP packages.
But the vendor thought really that it was a quad quad-core, after he had contact with Intel, we found out it were indeed quad dual-cores The appologize and will sent next week the right CPUs So we will play with them
