Errata
52 Specification Update
KBL097
Processor Graphics May Render Incorrectly or May Hang Following Warm
Reset With Package C8 Disabled
Problem
Processor Graphics may not properly restore internal configuration after warm reset
when package C8 is disabled.
Implication
Due to this erratum Processor Graphics may render incorrectly or hang on warm
reset.
Workaround It is possible for the BIOS to contain a workaround for this erratum.
Status For the steppings affected, see the Summary Table of Changes.
KBL098
Using Different Vendors For 2400 MHz DDR4 UDIMMs May Cause
Correctable Errors or a System Hang
Problem
When using 2400 MHz DDR4 UDIMMs from different vendors within the same
channel, a higher rate of correctable errors may occur or the system may hang.
Implication
Due to this erratum, reported correctable error counts may increase or the system
may hang.
Workaround None identified. Use a single vendor for 2400 MHz UDIMMs
Status For the steppings affected, see the Summary Table of Changes.
KBL099
Two DIMMs Per Channel 2133MHz DDR4 SODIMM Daisy-Chain Systems With
Different Vendors May Hang
Problem
When, on a single memory channel with 2133 MHz DDR4 SODIMMs, mixing different
vendors or mixing single rank and dual rank DIMMs, may lead to a higher rate of
correctable error to system hangs.
Implication
Due to this erratum, reported correctable error counts may increase or system may
hang.
Workaround
Use a single vendor for and do not mix single rank and dual rank 2133 MHz DDR4
SODIMM.
Status For the steppings affected, see the Summary Table of Changes.
KBL100
Unpredictable System Behavior May Occur in DDR4 Multi-Rank System
Problem
Due to incorrect configuration of DDR4 ODT by BIOS, it is possible for a multi-rank
system to violate section 4.27 of the DDR4 JEDEC spec revision JESED79-4A.
Implication
Due to this erratum, complex microarchitectural conditions may result in
unpredictable system behavior.
Workaround A BIOS workaround has been identified.
Status For the steppings affected, see the Summary Table of Changes.
