First it’s not as fast for single threaded loads :)

As for motherboard stability. Something has to either be wrong with your RAM or the fact that the SM board doesn’t properly support the 2696 since it’s an OEM chip. I have an X9 DAE running Windows 10 and it’s never crashed. I have no issues with Suspend.

Yeah, i know about single threads but we don't get these things for single thread..

I looked at the page for yr MB. They have a bios update in 2016 after win10 was released. Both of the boards i have issues with X9DRE-LN4F and X9DAX-iF has the last bios update in May 2015 before win10 was rel with no more bios update after that

Furthermore, i also looked at the manual for DAE. It listed the presence of S1 and S3 mode under acpi. for DRE and DAX there is only S1 listed. This makes me think that there is something different regarding ACPI support between these boards. If you search around this forum, there are several other threads about MB instability with windows 10. The Asrock 2011 v1 board is the frontrunner. It will do fine with 7 or i think server 2012 but will not run 10 stable.

The ram was good in my D30 running 2670 so i don't think it's ram. i could run e5-2670 to test it out about oem cpu support but i doubt it.

also there has been problems with ACPI and supermicro boards before:

X9DAi: Windows 10 BSOD ACPI_BIOS_ERROR

So count yourself lucky that win10 is working perfectly for you.

Btw, I am running the latest ver of win10 1703. So i don't know either if that's also make any difference.

guess I could try that but the problem I ave is that it have frozen several times after the first reboot... so that's might not be the total answer either

Make sure you follow it exactly. It sounds silly but your cable really must be unplugged.

did not make any difference as it locked up on initializing windows on the 2nd reboot. only by turning off suspend under acpi setting does it help to have some stability but still get some random lock up once a while. I think this bios incompletely compliant with win 10 acpi is the problem..

Since your MB has the S3 sleep option for acpi, i think it's more compatible. I did not have any problem running win 10 with s2600 or lenovo d30 and both of them did have S3 sleep mode.

I want at a min single thread that is faster than my work laptop. I’m in for likely 2667 V2 maybe 2690 V2. But not really interested in 2696, especially when you are having issues.

I’m also interested in Xeon W but that is a whole different game.

i don't think my current problem is b/c it's a 2696. i think it's more likely the MB chipset and bios that's my problem...

me too. hate to buy cpus that have single core slower than my 2012 laptop.

but its the same problem with v3s and v4s!

intel finally seem to wisen up with i9 cpus and maybe the next gen xeons will turbo better also.

see it wrong? the laptops run 3.6-4ghz

the turbo is weak on xeons basically. its bad for flexibility.

I've never seen one laptop over 3.5ghz. They may turbo boost up there, but its only for a short time. These Xeons stays stable on their turbo with full load on one core.

for one mobile cpu, intel quote 3.1Ghz base/4.0Ghz turbo

when you say they only boost a short time, what do you regard as short time? and how does intel specify when they will reduce the turbo on the single core load?

Underclocking happens when temperature is high. Same applies to the Xeons if you bake them to 100 degrees. This mobile CPU is innocent.

i also doubt the laptop can stay max turbo for that long given the limited cooling.

The other problem with xeon also is that it's real hard to keep turbo to only 1 core due to the fact that almost anything (moving mouse, background housekeeping tasks, etc) will trigger the 2nd core and reduce yr multiplier...

On a 2696 v2, means that you go from 3.5Ghz to 3.4Ghz, which is normal, just like with other CPU's.
