Every part is the same except for the intel Arc gpu that I can see the power usage on. It would be awesome to have a single thread with all of the tweaks to these CPUS (not just the power saving ones). Thanks again for all of your help with these builds.

you can not expect a similar idle power like the 14900K (7Watts package in windows)
you use quadch. RDIMM, not dualch. UDIMM and so on. all power saving tweaks will make the system more lazy/laggy,
if your system sleeps all the time, why you upgraded to 64 core EMR ?
Agreed, Desktop grade 14900 has all the sleep-states and can go into stand-by, this Xeon is a very different beast and you can't put it into sleep mode.
I think you're overthinking the question. It was simple if there were any easy power saving features that could be enabled. I'm not overly concerned with it. The CPU is great because of the cores, but the real reason I upgraded was for more ram and PCIe lanes. The cpu isn't much faster than a 14900k in the end. Overall I'm happy with the swap.
*on edit* Simply setting the power management from OS control to bios control and enabling balanced profile seems to have dropped idle system power to 300W. Still boosts fine to 4ghz.

Change to OOB and balanced power. Dual socket on MS73, and with PL1 to 200w, I can idle 150w. This way if I am not using cores, it does not change all cores to 2800ghz PL1. (Also trying to downsize QYFR system with MS73 but no idea where, Ebay?)

Hello everyone. Can anyone who has experienced spr es tell me if there is any major bug? Some friend of mine told me that the 4th generation of Xeon ES are full of bugs. Is that true? If so, typically what kind of bugs? Will I be affected when running some Python and C++ code?
there are many ES stages. the early ones have usualy more bugs, for that reason next ES are made with some bugs solved.
We use mostly SPR stepping D0 ES2, they are prior to final befor intel decided to redesign silicon(die shrink)
But so far many people run Windows 10/11 without issues, so i guess that will not be possible with major bugs.
you may not able to use the accellerators, but i think it is because the final intel drivers don't like to work with ES accel.
no.
btw: the SPR final prod.units have over 100 errata left.
AMD does not provide errata lists, but i doubt it is beause there are none.

production, QS.
once a series was launched, who interests any errata of superfluous ES ?
QS = prod.unit + ES bit set
Code:
014US
Added Errata EMR143 to EMR144.

What are some good ICX ES? Want to upgrade from Xeon Gold 6326 on Supermicro X12SPL
Any cheap Stepping 6 out there? Or any other recommendations?

I have been using QYFS and QYK8 for more than a year now, never had an issue or crash. I used them for lightroom and software development; The only problem is that software cannot take advantage of so many cores. 13700k beats them for all my usage scenarios. May be they run slow.
Hi, hope you don't mind me asking a question without first researching this thread, but i was wondering if there are any interesting ES/QS xeons at the moment, that work in LGA2066 socket c422 chipset motherboards. like Gigabyte or Asus ATX sized ones?
Just kinda looking around for a cheaper alternative to W680/W790 that still takes rdimm..
edit: the XeonW-22xx series seems to support 2933 rdimm, and looking at various c422 based motherboards and prices of these xeons from china i'm starting to feel like i want to build a c422 based system in ATX case... maybe..
I promised myself wait for nova lake before doing anything though.. :\

this is overpriced i guess because they work in iMac pro's.
same situation than LGA3647, 2ndt gen expensive, 1st gen cheap because left from upgrade.
and there is an unspoken rule: the more expensive the motherboard is, the cheaper the ES.
lol, come to think of it, seems so.. no free lunches
Better not do buy anything before nova lake, if it's good, might make all these old school xeons cheaper? i mean lots of cores for consumer prices.. i don't know
