Newest AMD AGESA Firmware Inadvertently Disables Cores On Some Ryzen 5 7600X CPUs

It appears to be like like AMD’s newest AGESA ComboAM5PI firmware has achieved extra hurt than good. As tipped by {hardware} leaker chi11eddog (opens in new tab), the firmware reportedly disables some cores on the Ryzen 5 7600X, prompting numerous motherboard distributors to tug the replace from their web sites.

The flawed firmware would not have an effect on all Ryzen 5 7600X, probably the greatest CPUs. It solely impacts the samples that leverage a dual-CCD design. Given the Ryzen 5 7600X’s hexa-core, 12-thread configuration, a single CCD is greater than adequate. Nevertheless, some Ryzen 5 7600X processors arrive with two CCDs underneath the hood. Clearly, AMD fused off the extra CCD, so you possibly can’t simply magically unlock extra cores.
