    MCB193A-FCAT possible crossflash?

    Ok so probably no chances to use CB194 as a 40/56/100GbE cards (without internal Mellanox SDK for mt4113 chip). What is maybe possible to make, is: CB194a as a IB and do ~110GbE via EoIB (dual port and x16 PCIe 3.0) so few CB194a cards for $17 + ~$200 IB switch ;) probably don't make any...

    overclocking Xeon E7 8894 v4 (x8) inside Lenovo X3950 X6 - "all core boost" ?

    True, v0 was good up to... 4 cores (for example 1620 is almost identical like 1620v2) 6, 8 cores much better in v2 (1650 v2 is much faster than 1650 or 1660) 10,12,15 cores not available in v0.

    overclocking Xeon E7 8894 v4 (x8) inside Lenovo X3950 X6 - "all core boost" ?

    It's not that bad, SMI almost double the speed. E5 v0: 1600MHz factory E5 v2: 1866MHz factory E5 v2 overclocked (1650v2/1680v2): 2133MHz (Samsung 1866MHz DDR3 ECC) E5 v3: 2133/2400MHz factory (~2666MHz overclocked DDR4) E7 v2: 2666MHz (SMI) E7 v4: 3200MHz (SMI2) Trick is you need 2 dimms per...

    overclocking Xeon E7 8894 v4 (x8) inside Lenovo X3950 X6 - "all core boost" ?

    This is my FV: Model 6241, came with 8x E7-8880 v3 and 256GB DDR4 from Germany. 8880 v3 are super super slow, so replaced to 8x 8894v4 - and just worked, no issues at all (and upgrade to 2TB, 64dimms), no firmware upgrade. --- for example upgrading HP DL580 G8 4x E7-8895v2 to "G9" 4x...

    Sapphire Rapids-WS / Xeon W9-3495X

    yes :) AVX512 is wasting of the silicon (let's commit this job to the graphics cards), but probably bfloat16 is tiny and might be needed soon (and here CPU is faster than memory can deliver)

    Sapphire Rapids-WS / Xeon W9-3495X

    it's too slow... something is wrong here. If it is based on the similar cores like 13900K (P cores) it is not boosting yet to 4.6GHz but maybe ~3.0GHz. E5 v3 @ 4.6GHz is faster (single core).

    Sapphire Rapids-WS / Xeon W9-3495X

    mmmmm.... Single core performance like overclocked E5 1660 v3 (or not overclocked i7-8700k) Multicore just slightly faster than i9-13900ks... looks like slightly upgraded Xeon Platinum 9282 from 2019 (2nd Generation Scalable, 56 cores too) IPC is on the i7-8700k / i7-7700k / i9-7940X / TR...

    MCB193A-FCAT possible crossflash?

    Wow!!!!!! nice progress! On which CX firmware the card was visible for the system and says it's connected? 5th gen / 4th gen - are you talking about CX-IB gen ?

    overclocking Xeon E7 8894 v4 (x8) inside Lenovo X3950 X6 - "all core boost" ?

    I think it can be thermal paste on CPU pads or LGA pins. SMI is between CPU and Jordan Creek chipset, swap CPU's between books and check. I have experience just with 2 of them: 4x 8895 v2 - about 37000 in R23 4x 8894 v4 - about 62000 in R23 8x 8894 v4 - not working in CB R23 (too many...

    overclocking Xeon E7 8894 v4 (x8) inside Lenovo X3950 X6 - "all core boost" ?

    Complicated. Yes, I ran 4x 8894 v4 on DDR3 but inside HP DL580 G8/G9 with SPI board from G9 (also in theory support DDR4 only). DDR3 was maybe 1% slower than on DDR4 in benchmarks (in R23 even slightly faster- lol, ~62000 points). When having HP DL580 G8 and G9 at the same time you can also...

    overclocking Xeon E7 8894 v4 (x8) inside Lenovo X3950 X6 - "all core boost" ?

    Yes, if you are talking about 1 or 2 NVMe it's not a problem and everywhere will achieve 3.4-3.6GB/s but still closer to CPU1 is better https://lenovopress.lenovo.com/sg248208.pdf Page 22 (page 40 in PDF) So slots connected to the CPU1 are the best: Any slot in "Storage book" (one of them...

    Xeon E7 8894 v4 - what type of Memory for best performance (single core)?

    You are super close ;) E7 v2/v3/v4 support 24 DIMMs per CPU. so it is "6 DIMMs" per CPU channel or "3 DIMMs" per Jordan Creek mem buffer chip channel Not possible here :/ (possible on E5 v2 even on DDR3 -1680v2 also possible with E5 v3, I think up to 2600 or slightly more when overclocked -...

    Xeon E7 8894 v4 - what type of Memory for best performance (single core)?

    In HP DL580 "G9" it was from ~320W up to ~1200W 1TB 64x16GB DDR3 1866MHz @ 1600MHz 4x E7 8894v4 (4x 24 cores)

    overclocking Xeon E7 8894 v4 (x8) inside Lenovo X3950 X6 - "all core boost" ?

    Yes, it's on the NVMe. 1 for system (970 Evo +) , and 12 for data (older 970 Evo not plus), one Mellanox 2x100GbE, one Geforce 1050. It's almost like a standard PC. I have 2 "books" for SATA 2.5" drives (not using it, but tested and seems to be quite fast, ~7GB/s to cache per "book", 8x SSD...

    Can I escape ThreadRipper PRO with AM5?

    I skipped LGA3647 after bought LGA2066 10gen i9 and see almost same results as 1660v3 ;) (10 cores vs 8) but you are right coworkers here are using i9 or 5950X (now first 7950X "arrived") and when don't have to re-compile everything they are fine: Spec is like this: GPU slot divvied into 2x...

    Can I escape ThreadRipper PRO with AM5?

    OK, your bar is (slightly) longer than mine! (what about CB R23?) but.. others have much longer bars for example gamers! equipped with 13900kf. so our CPU's are still.... sloooow!

    Can I escape ThreadRipper PRO with AM5?

    Builders don't require lot of them 4xNVMe is very good especially when PCIE 4.0 1x NIC 2x 100GbE is ok RTX connected to PCIe 3.0x4 ;) memory is a problem - should be supported by NVMe drives if not possible to install 512GB. so AM4 AM5 and Z790 is ok

    Can I escape ThreadRipper PRO with AM5?

    btw. @DaveLTX please make the CPU-Z test because I am fan of the Passmark you are fan of the CB CPU-Z will be independent. And I am not fan of anything history of my PC's that I personally was working on: AMD 286, Intel 486, AMD K6, AMD A64, Intel Core2Duo, i5, 1650v2, 10885H. Probaly your bar...

    Can I escape ThreadRipper PRO with AM5?

    Agree (in most cases ;) ) and this was the reason to make experiments like this: 2x2697v2 <- first builder 4x 8895v2 <- second builder TR3970X <- third one 4x 8894v4 <- mistake (better to use 5950X, AMD is slower but not that much) 8x 8894v4 <- fifth try (yes, faster than 7950X and 13900kf...
