the BIOS is checked at every power up by RoT mechanism. if validation fails the BIOS is restored from Backup(flashdisk)WHAT IF I simply desolder the 256MB flash chip from the X13DEI/DAI board and write in an unsigned modded BIOS that contains ES microcodes with a programmer?
it is not encrypted, it is signed with a Private Key (Cert,supermicro)Update: hmm I guess the first problem is that we cannot decrypt a signed BIOS to see its contents?
you go with Gigabyte MS73-HBx, latest BIOS still support D0 ES.My desire lately is building a 4th gen dual Xeon rig with some cheap D0 stepping ES CPUs.
Yes I already learned that but I had bad experience with buggy GB boards from the LGA3647 era. Might give it a chance again.you go with Gigabyte MS73-HBx, latest BIOS still support D0 ES.
i run QYFP,QYFQ and more on MS33-AR0 BIOS F19 i.e.
check the step 4, E0 steppings, costs a little more but much better compatibility.My desire lately is building a 4th gen dual Xeon rig with some cheap D0 stepping ES CPUs.
and did somebody test Asrock Spc741d8 if bios can be modded? (i know its single socket, but "very" cheap)check the step 4, E0 steppings, costs a little more but much better compatibility.
Q0KL i.e.
as you can see on the ASRock Rack SPC621 series at some BIOS rev.UPDATE2: With MC Extractor there are all ucodes 6F4, 6F5, 6F6, 6F8, so E0 earliest by stock BIOS, but can it be modded?
ASUS do not have retail LGA4189 boards???.What about Gigabyte or ASUS?
I have an ASRock Rack SPCC621D8 and the C0/L0 ES CPUs work on BIOS 1.20 and 1.23, but nothing after that.
Thanks !ICX ES QVM8 runs on Gigabyte MU72-SU0 and the latest bios F23.Gigabyte retains support for non-PRD steps
QVM8 (C0) ES2 is as good as (D0) ES2 but mostly more power.Should I use D0 ES to make it better?They're cheap now
No!I just had a fatal screen freeze, the keyboard and mouse screen was unresponsive, the audio continued to play, and the bmc and OS logs didn't give me any reports after the resetQVM8 (C0) ES2 is as good as (D0) ES2 but mostly more power
and you are sure that's ES issue ? have seen many reports like this with retail processors.No!I just had a fatal screen freeze, the keyboard and mouse screen was unresponsive, the audio continued to play, and the bmc and system logs didn't give me any reports after the reset
All bios is the default. They have been running normally for 48 hours
I have never encountered such a problem with ICX ES, many people have told me that ICX es is good, but it is the most likely culpritand you are sure that's ES issue ? have seen many reports like this with retail processors.
ICX ES1 are very bad. avoid them.I have never encountered such a problem with ICX ES, many people have told me that ICX es is good, but it is the most likely culprit
and IF the ES is a bad one, just ask the seller for SWAP em.many people have told me that ICX es is good, but it is the most likely culprit
D0 step 6 is PRD microcodeQU98 es1 but QUYR es2?QV2D es1 but QVM7 es2?only D-step is really ES2.
if you want them to run on every motherboard step 6 D0 is your choice of course.QU98 es1 but QUYR es2?QV2D es1 but QVM7 es2?only D-step is really ES2.
Very interesting, this es1 QV2G has been working for almost a year without problems (seller said),I'll replace it, all mem channels are goodif you want them to run on every motherboard step 6 D0 is your choice of course.
ES1 have the issue of loosing memory channels over time.
