I think it means good IOH chip.

Basically, under 240 - 250MHz, BCLK limitation based on IOH chip quality.
Good IOH chip can run over 240MHz with x36 QPI link speed.
Average IOH can run around 220 - 230MHz with x36 QPI link speed.
Bad IOH chip just only run under 210 MHz with x36 QPI link speed.

The first you check your IOH QPI limit.
You can check QPI link limit with x12 CPU multi, easilly.
(If x36 QPI link & slow mode limit are same, it's CPU BCLK limit.)
