Latest bios seems to be working, however, (a) unable to select memory speed (b) have to amend the cpu c states
Regarding (a) I wonder if there is version of AMI bios editor that is compatible with this bios file so we can re-enable the bios menu items for memory speed settings.Latest bios seems to be working, however, (a) unable to select memory speed (b) have to amend the cpu c states
no.Is there a list of all of the ES Xeons for this board and their max clock speeds?
I appreciate the response. I believe you mentioned that the QYFS will do 3.7GHz with half the cores disabled? Do you know if there are any higher max turbo speed versions? Thanks.

theoretical bandwidth never fits. depends on the used benchmark software. and AIDA64 e.g. just adds results of all cores, you never know what the per core bandwidth is.my rough math says 300+ approx but want to make sure it is approximately correct?
My current setup with Emerald Rapids Q2SR, GB MS03-CE0, and 8x32GB Micron 5600MHz have bandwidth:I have a question, W790E-SAGE says that it has octa channel memory. so theoritically with 4800MHz DDR5 ram, how much memory bandwidth can we get on this, has anyone run any tests to confirm it, can someone please let me know?

That's a big increase, do you think it's just the change to Emerald Rapids? My QYK8 has similar memory bandwidth compared to your Q2SR with 4800MHz sticks. I do have a Q2SR on order though...My current setup with Emerald Rapids Q2SR, GB MS03-CE0, and 8x32GB Micron 5600MHz have bandwidth:
AIDA64 7.60.7300 - Memory Read 313,19 GB/s Write 251,39 GB/s Copy 278,45 GB/s
My old setup with Sapphire Rapids QYFS, AS W790E-SAGE, and 8x16GB Kingston 6000MHz had bandwidth:
AIDA64 7.00.6700 - Memory Read 234,30 GB/s Write 173,16 GB/s Copy 188,02 GB/s
that is often happen if the user is not brave enough.I read in an earlier reply here suggestions to reseat the CPU. I decided to try tightening the heatsink down before going through a full re-seating. Sure enough, the screws were just a tiny bit loose.
Or does not have a torque control screwdriver. I mean these plastic nuts are scary.that is often happen if the user is not brave enough.
i turn until it stops turn...a hundret times so far, all best with plastics. with a torque driver you fasten some more, but it does not turn anymore.Or does not have a torque control screwdriver. I mean these plastic nuts are scary.
The smallest torque device I have starts at 10 inch-pounds, which is > 1 Nm. The Noctua NH-U14S DX-4677 doesn't have a torque specification but I've read to use 0.8Nm for other devices. I just tightened by hand with the supplied torx wrench until it was 3 fingers tight.Or does not have a torque control screwdriver. I mean these plastic nuts are scary.
It has to be a combination of the higher memory frequency supported by Emerald Rapids and 2Rx8 RDIMMs (or am I wrong?). As far as the memory read bandwidths go, here are the numbers posted by different users in the forum:That's a big increase, do you think it's just the change to Emerald Rapids?

I bought specifically for the LGA4677 socket a Wiha torque screwdriver, plus an attachment. One disadvantage is that it is not cheap, but it is of good quality, and I can adjust the torque as I want (I bought variant from 0,5 to 2 nm).The smallest torque device I have starts at 10 inch-pounds, which is > 1 Nm.
