AGP bug in Intel's workstation chipsets

Most should know that Intel recently released new chipsets for workstations. But the fact that these also have several errors in the newly implemented AGP3.0 specifications should have been unknown to most of them.

However, Intel sees no reason to fix these errors, as they can either be fixed by a BIOS update or a slightly modified board layout. The E7505 (Placer) has two errors. The first concerns the AGP signals, which do not correspond to the AGP 3.0 specifications, so that data corruption in the AGP interface can occur. The second error concerns the AGP Prefetch Cache, which must be switched off, otherwise system crashes can occur. You can read about the errors under 'Errata' in this PDF document at Intel. These two errors seem to affect the E7205 (Granite Bay) as well.

In addition, Intel subsequently changed the voltage specifications of the E7505 from 1.2 to 1.3 volts. You can read more about this in this PDF . In January next year, however, a new revision of the E7505 should come onto the market.
