Reverted back to 0805, manually selected the memory, also amended the c states and all working fine now...

Seems anything beyond 0805 their is no xmp or memory selection

Sorry if this has been answered already. I was going to build an Epyc setup but that kind of was an epyc failure hah. Is there a list of all of the ES Xeons for this board and their max clock speeds? For some reason I thought I've seen it before but can't find it.

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?
QYK8 D0 56c 1.9 - 4.0Ghz(1-28c) 350W ebay link
QY0C D0 32c 1.8 - 4.0Ghz(1-16c) 250W (rare one i have, taobao/goofish only)

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?

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:
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'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...

I just got another 4 sticks of RAM for my SAGE-SE board to match the existing 4. Except DIMM slot H1 wasn't recognizing any stick. 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. After snugging up all the screws in sequence, all 8 channels were recognized and trained successfully, taking a standard XMP OC without problems.

Or does not have a torque control screwdriver. I mean these plastic nuts are scary.
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.
btw: the plastics is intel norm/standard and can be replaced.

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.

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:

QYFS with 1Rx8 - 230-240 GB/s
QYFS (or even retail 8480+?) with 2Rx8 - 271.53 GB/s (see https://forums.servethehome.com/ind...cie-root-complex-discussion.42917/post-408196)
Q2SR with 2Rx8 - 313.19 GB/s

These numbers make the theoretical bandwidths look quite meaningful after all.

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).

I have an Asus W790 Sage-SE with Q071 32C/64T. Current status is booting to BIOS as I have yet to install an OS.
Is there any reason to have a BIOS other than the 0215 original BIOS? Does it provide benefits/stability/features to update?
Otherwise, I was going to attempt to flash my system to 0215 (it was received with a later BIOS).
