Interference from outside. It's general rule, the longer the signal path the more chances of intereference, even motherboard's internal PCB traces suffer this rule, that's why M.2 right next to CPU is ULTRA speed.

Example, the power cable cannot run parallel next to signal cable, this is 100% signal degradation, the best option is power run 90 degrees perpendicular to signal, but easier said then done..... when space constrains, cable length, cable tidyness management are required.


opppssss wrong link previously, edited to correct link below.
eg power cable run parallel to SN770 adaptor card might be bad signal integrity

@Nightlane

My current setup betting on shortest path SSD and attempting PCIe Gen4 SN770@pcie2 and RX6900XT@pcie3, because bios must 8x 8x both plugged in item must be Gen4 hence can't fit Optane900p@pcie2 forcing it to be in M.2socket1 using adaptor.

if the interferences come from their own wires, well, if you feel crafty you can separate the wires and insulate them separately. It will end a bit shorter.

About possible power drop, hmmm, I think distance should not be important if the wires are decent. Probably you can try to use a potentiometer to check it?

If the power loss is a thing, you can try to weld a new cable + connector to the pcie connector directly.

I had this one (and I returned it)

https://www.amazon.es/dp/B08C7YBRFC

the power is on the right side and it looked pretty high quality. (and it was like 40$)

Is the interference between its own wires? If the interferences come from outside, I think you can add the right cover to insulate it.

15cm long extention cable grey color suspect thin wires bad score at M.2 socket 1, where power socket far from optane900p, may be power lost through 15cm cable also.

@Nightlane, good to hear from CPU temp not high....

I want to give you more hope, check out below. My best score using bios 6.62 2021 April 20, optane900p score 7020 in pcie2 with a HiKvision 512GB score 4802 in M.2 socket 1, Notice the pcie lane allocation as well as 8Gb/s=gen3 versus 2.5Gb/2=gen2 on GPU shows currently used, other testseses plus various details and information.

the AMD chipset package also date around 2021 April 20th +/-

the bios version and chipset version makes a big difference. I've always known this, but because we need better ram compatibily support using newer agessa plus resizable bar, hence sacrificed SSD performance :(

The chipset vulnerability problem also stole some performance from CPU, causing lost of score in AS SSD.

test was with M.2 set to Gen3
http://www.my-acoustic.com/images/07%20bios%20full%20manual%20all%20full%20lane%20speed.png

I recall may be overclocked the CPU manually to get high score, hence please try manual CPU overclock as high as you can.



Below a test with singular optane900p without M.2 E2000 512GB

You seem to be a very well DIYir handy man....... would you be willing to try using a single small drop of epoxy glue to secure it ???

Or get a rubber lock thingy for M.2 https://item.taobao.com/item.htm?spm=a230r.1.14.74.15616453HtL7BH&id=620459037990&ns=1&abbucket=9#detail

or a complete new set of nuts+bolts and top_bolts (pain in the ass to take out mobo from casing :(

modern mobo uses flip switch 90 degrees to lock the M.2 no longer uses screw, try to look for it if you have time.

My mobo picture link below, same x370 taichi as you and my optane900p is 280GB version same as you.

http:www.my-acoustic.com/images/IMAG8995_2023feb23_optane900ppcie2_SN770M.2-1_6900XTpcie3_RX560_pcie5extention20cmCUTshiftoneslot.jpg

The reason I setup such weird way is because will try this weekend PCIe ver4.0 16Gb/s speed per lane using beta bios from old to check if can achieve 7000MB/s for SN770 at pcie2 and 6900XT run PCIe ver4.0

2023 Feb 23
optane900p 280gb @ pcie2
SN770 1TB @ M.2 socket 1
6900XT @ pcie3
RX560 @ pcie5 plus extention cable 20cm then CUT GPU bracket shift one slot to give more air space to 6900XT. For AMD Fluid Motion + Blusky Framerate Convertor output 144hz on the fly smooth video less judder
