Hi Kyösti, I will try to boot again with 6276+6238 with the current build and I will inform the result. Regards, - Eli On 03/05/18 20:07, Kyösti Mälkki wrote: > On Thu, May 3, 2018 at 8:57 PM, Elisenda Cuadros wrote: >> Finally I acquired another 6276 CPU (it was the fastest and cheapest >>

Finally I acquired another 6276 CPU (it was the fastest and cheapest option). It works perfect. If I can try (in the future) another different 16-core CPU, I will report the result. Thank you for you kind support. Regards, - Eli On 11/04/18 21:30, Timothy Pearson wrote: > This may be a genera

But it would be possible to have two CPU's with the same core count but differing frequencies? Thanks 0xDF372A17.asc Description: application/pgp-keys -- coreboot mailing list: coreboot@coreboot.org https://mail.coreboot.org/mailman/listinfo/coreboot

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 This may be a general coreboot limitation at the moment. The compatibility sections for mixed CPUs in the BKDG are more concerned with total power delivery and proper P-state setup than anything else. If I recall correctly, coreboot assumes both CPUs

Thank you for your reply Timothy. Vendor Bios doesn't print any special message regarding this. In fact it shows a total of 28 cores (16+12). I thought mixing CPUs from same families was supported. Regards, - Eli On 11/04/18 20:44, Timothy Pearson wrote: > I don't know if coreboot has support

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I don't know if coreboot has support for differing CPUs in the same mainboard; it's not something I can recall testing at any point. The failure is occurring far before memory initialization, in CAR, in core setup. I'd guess it has something to do wi

Hello, After testing the board for some weeks I bought another CPU (6276). I installed this into CPU1 slot and a 6238 in CPU2. I checked that both CPUs are shining and also the memory (Micron MT18JSF25672PDZ-1G4F1DD, populated in A2/C2/E2/G2 slots). The problem is that Coreboot seems to hang at
