SPR-SP D0 ES work with Gigabyte up to R12/R17 BIOS (varies with model)
CSI/MRC 114.D30 = work
CSI/MRC 115.D14 = not work
mod. BIOS required in any case for SPR D0 and EMR A0 ES, i have D0 and A0 working on ASRock Rack C741.
later SPR-SP E0 stepping work (but not early E0 like Q03J e.g.)
QS is Retail silicon just with ES bit enabled, work on all motherboards who support the Retail version.
I saw that you also used the Q30H and Q2Y7 with asrock (EMR A0: Q2SR,Q2SP,Q2Y7,Q2Y8,Q2T7,Q30G,Q30H...)
Besides the boot time issue, has either chip given you issues with asrock c741 or anything locked/disabled?
Seeing as I won’t be able to get the amount of ram I want right away, do you think it is worth locking into EMR over SPR (excluding qs/prod and assuming only es)?
Is there a chance to use the latest bios or are we locked to early/beta bios indefinitely? Coming from AMD ryzen/threadripper many times latest bios fixed something and asrock has beta bios available for EMR or release bios for SPR.
Do you happen to be in the US? Any issues with customs, tariffs or shipping speed compared to eBay purchases? Price is a 3rd from goofish but ebay says imports included and can return (minus shipping and import fees).
Do you have a referral code for superbuy? If you do, share it and I’ll use it.
