which 8490H ES ?
8490H ES step 3 D0 QYFX = no ( or with unofficial BIOS 1.0 is full of bugs - you can't downgrade, needs soldering )
8490H ES step 4 E0 Q03J = yes.
Hi,
I ordered step 4 EO CPU and Supermicro X13DEI-T motherboard but no display. After the power its shutdown.
Do you have any idea ?

Current Config
2 x 8490H ( Q03J)
Supermicro X13DEI-T Motherboard
2 x 64GB DDR5 ECC

Is it need any bios modification ?
I downgraded bios 2.1 to 1.1 here is the current firmwares.
But i didnt downgrade CLPD or BMC only downgraded BIOS.


Thanks.

have seen Q03J orking on X13DEI but i have noticed Q03J E0 is still not same than other E0 like Q0K?
Q03J runs not on ASRock Rack SP2C741 but Q0K? do work.
Possibly you need BIOS 1.0 - unfortunaly this can only be flashed by hardware programmer.

2 questions:

1. Has anyone see any benefits of using early E0 chips over D0 chips on W790 platform? Are these chips any better? I only read that they may have lower idle power consumption.
2. Are accelerators available/enabled on QYFR? How can I check that?

Confirmed QYFR doesn't have accelerators.
QAT accelerators are not elements that HWinfo uses to differentiate between processors. QYFP e.g. is very similar to QYFQ, but unlike QYFQ it doesn't have any QAT.
