the second one looks best, but you have to be aware, that there will be space and heat issues with the ssd as even that cable isnt exactly flexible. so you wifi card would be laying on top of the ssd.
What!? Wym? The wifi card slot is below the ssd and since the second one adapter has that ribbon cable, I would fold it to make the wifi card be in the center of the motherboard, pretty much like the WIFI/NVMe adapter that CWWK send with the mini pc. So the SSD would actually have less heat problem since there's nothing below it, and the wifi card would get fresh air directly from the fan above it.



is there a chance cwwk sends that adapter anyway so that you can try for yourself?
i would ask how much they charge for the adapter.
cant imagine why it wouldnt work (other than it not mechanically fitting inside the chassis)
Yeah, I could try to ask them. I just don't want to be seen as stubborn asking for something that they've already tried themselves. I don't think they would just lie about it, since I told them I would purchase from them (I was not asking that as a gift or something like that).

ok i made a mistake there. you have an m.2 adapter to mini-pcie. that means you will be using the default adapter anyway so all the cable and the wifi module will ne next to the ssd and not below it.

you wont even need to fold the cable i think.

sorry for that.

:p don't worry about it and thank you for your feedback.

I wish I could find a PCB adapter like the one CWWK send with the Mini PC, so it would be automatically centered in the board while providing me a Mini PCI-e slot.

I've never done any PCB request and so on, do you think I could find some company to make this adapter for me from scratch? I could take all the measures from the original one, but instead of having a M2 M key for SSD, I would ask the company to use a Mini PCI-e slot. I just don't know ANYTHING about PCB's, so I actually don't know the traces and what could be done or not (I'm kind worried of frying something by using a non-tested adapter).

I noticed the same here, both the 06-08 and 02-27 from fta seemed to give me the same result.
It seems like the keyboard is working fine, moving up and down on the first page seems ok, but hitting left-right to go to the next section makes the screen freeze, even the time stops updating.
I'm wondering if it would be a "menu" issue, not quite a keyboard issue.
Strange, it's working perfectly for me. Perhaps try restoring defaults in the BIOS, or alternatively clearing the CMOS with the button on the front?

I received the same cable in my order. Haven't even found a header to plug it in to though

Funny enough, they're having a "what cable is needed for the fan" conversation in another thread for a different box, and this cable looks like it could be the cable for going from that box's proprietary 4 pin fan connection to a standard 4 pin.

I have the same problem. Clearing CMOS does not help, and left/right arrows are hanging the BIOS.
I've even tried the old Sun Microsystems keyboard I had lying around, and I've seen no change.

When I switch to the USB 3 ports, I can manage few left keys jumps before the freeze, but with USB 2 it always happen on the first press. Maybe some kind of IRQ problem?

That's why I have to stick to the stock for the time being :/

OK my new memory arrived (2x32GB G.Skill Ripjaws), and I've finished tweaking settings. New Passmark score for my i5-1240P...

Code:
                          PassMark PerformanceTest Linux

  Memory Threaded                  39712 MB/s
--------------------------------------------------------------------------

My first CPU Mark score, as I received the device, was 14050 (first result here). That's a ~55% increase! A big part of that increase is down to switching from the single SODIMM to dual channel, massively improved the Prime Numbers, Sorting and Physics scores.

AC Loadline = 180
TDC Current Limit = 680 (ICCMax for the i5-1240P is a bit higher at 85A)
TCC Activation Offset = 15
TCC Offset Time Window = 3 Sec
PL1 = 64000000
PL1_TAU = 28000000
PL2 = 64000000

I couldn't find this PL1_TAU. Can you show me where it is?
Stock Bios I was getting 16k in Passmark.
With FTA's tweaks I was reaching 18k.
With your tweaks now I'm reaching 19991. Almost crossing the 20k mark.
By the way, anyone else with i5-1240P care to share their benchmarks and what you have done in BIOS?
I was able to cross the 20k mark, but I couldn't find PL1_TAU in @fta bios. I don't know if that's why I coulnd't get a better score.

Anyone successfully got the igpu pass through working in prox on these boards (cwwk i3 1215u)? I've been running in to issues.

[drm] *ERROR* Failed to enable 7 VFs (-ENOMEM) igpu
not enough MMIO resources for SR-IOV

Trying to use This guide

**update
I found the above 4g setting in bios. All is good now, got my igpu passed!
Hello, which option in bios(besides vd-t) did you enable? I'm struggling with the same error.

There's an option in BIOS close to the ones we tweaked that says "Above 4G Decoding". Just enable that and you're good to go.
I don't remember where exactly it is, but I think it's in the same page as VT-d.

Guys, how can I check if it is the Mini PC or my PC that is not handling 2.5GbE properly?
I've installed OpenWrt in this Mini PC and did the passthrough (VirtIO) of the NICs into it.
My PC has a Gigabyte B650M AORUS ELITE AX which has a Realtek RTL8125BG NIC.
No matter what I do I can only get my PC to connect in 1.0 Gb speed. Does anyone know why?


I've even changed these settings to 2.5 Gbps Full Duplex, but it didn't help:


I tried both Gigabyte's and Realtek's driver and none of them worked for the purpose of connecting to 2.5GbE.
Now I'm worried that my Mini PC has something wrong with the i226-V NICs.

Via proxmox lspci -v returns me this:

Code:
07:00.0 Ethernet controller: Intel Corporation Ethernet Controller I226-V (rev 04)
        Subsystem: Intel Corporation Ethernet Controller I226-V
        Flags: bus master, fast devsel, latency 0, IRQ 17, IOMMU group 24
        Memory at 50500000 (32-bit, non-prefetchable) [size=1M]
        Memory at 50600000 (32-bit, non-prefetchable) [size=16K]
        Expansion ROM at 50400000 [disabled] [size=1M]
        Capabilities: [40] Power Management version 3
        Capabilities: [50] MSI: Enable- Count=1/1 Maskable+ 64bit+

        Capabilities: [1e0] L1 PM Substates
        Kernel driver in use: igc
        Kernel modules: igc
To make matters even worse I don't own any other device with 2.5GbE NIC and I don't know anyone else who does.

Now I need to see if OpenWrt also detects my NICS as i226-V or that it supports 2.5GbE by any other mean.
And I still can't understand what is wrong between this direct connection, shouldn't it be auto-negotiated to 2.5GbE?
I can't find in OpenWrt the tab for SWITCH, I remember this tab showing each tagged/untagged port and what speed it supported.

---Edit
I will install ethtool in OpenWrt and see if I get the same results.

Cable length and type are relevant as is the quality of the cable and termination. If you have hard bends that can mess things up.

It's less than 20 meters, high quality cable, Cat6 with a good termination. No hard bends as well.
