Congrats. It still seems to me that there's some other reason for the 6400 not working than some Lenovo trickery... One thing you might want to try and test with your original gpu is going into the bios and disabling "optimized defaults" so that you can load legacy option roms and use CSM. I...

Well, it's a discontinued system and I'd assume that the AMD variant wasn't very popular or something... I only found a single place where you could even buy one: Lenovo ThinkStation P3 Tiny Workstation | Core i7-12700 @ 4.9GHz | 12-Core | 64GB DDR5 | 512GB NVMe SSD | AMD WX 3200 4GB You could...

Yes. While it would be possible to make a BIOS that ignores certain hardware (and Lenovo has done this in the past with their whitelisting of wlan cards on laptops etc), I seriously doubt they're doing that for these computers (especially since it's extra work for no real purpose, and these...

Usually when this happens it's a problem with the riser... what model riser do you have? Do you have a second one to test? Could also check if the BIOS is set to use the integrated GPU only instead of auto.

According to intel that board has: Gigabit (10/100/1000/2500 Mbps) LAN subsystem using the Intel® i255-LM Gigabit Ethernet Controller • Support for two RJ45 ports with the Dual LAN chassis option So do these actually have 2.5gbe? (I did see the first post saying it has one I211, one I219-V...

I mean, I guess... but since you're connecting the clip directly to the chip and all of those components are on the other side of the connection between the chip and the clip, I don't think you have to worry about interference from those components to the point where unsoldering it from the...

How do the other components interfere if they have no power and you use a clip?

Yes. Note that depending on the riser you might only have x4 lanes, etc. Also, if your riser is a 01AJ902 model it might explain the issues you had with the video card detection, there are reports of issues with it.

If you've set it to PEG and there's no signal coming from the video card, the only way to "fix" that is to remove the video card and plug back into the onboard. (well, technically you could reset the bios) Have you confirmed that your nvidia card works? Have you tested any other graphics card...

Assuming its a 35w "T" variant cpu, I don't see why the default 65w wouldn't work.

I'm not sure what you mean by "mandatory exclude from bios", but there is a bios option for the gpu on these lenovo tinys. I don't have a p330 tiny, so I can't tell you exactly how to get to that option, but look in the bios for something like "Video Setup" in the "Devices " section... there...

Nice... I was using a sata to m.2 adapter along with an extension cable but it still took up too much space in my setups (and where I could fit it the drives I had on hand would over heat because they run hot and were sandwiched in). Well, I had some 32gb sandisks that didn't overheat, but I...

Man, these are awesome... it's too bad I mostly use m720qs, and my m920s are using that space for "full" length cards or I'd buy a few. Just out of curiosity, is that a bare sata ssd pcb underneath the m.2s in the picture?

Yes... which is why I said: The programmer gives you direct access to the bios chip contents, it doesn't care about anything... the computer isnt even on, etc. You can see plenty of people modding lenovo bios, theres even a thread here...

Not natively... you can (or at least, should be able to) modify the bios to add rebar support via ReBarUEFI, but you'll need a programmer (ch341a etc) because lenovo bios is locked down. You can enable above 4g decoding using the uefi setup_var method though. edit: fix typo

Just out of curiosity, has anyone tried using an Intel CC150 CPU in a m720q/m920q/m920x ?

If you're only going to use it for AV1 transcoding, you probably don't even need resizeable bar enabled... I think I remember reading somewhere that it's only a minor performance loss in that use case.

Yes, I've removed the antenna bracket to make them fit in mine. 167mm (aka 6.60 inch) is kind of the "standard" for HHHL (half height half length) cards, which is why basically everything is 167mm. Do shorter cards exist? Yes. They will be much more rare and more expensive. If you really...

1) a lot. I personally have one with an LSI 9280-8e, and another with an Areca ARC-1882X (with optional management port daughterboard removed to make it half height). 2) You can definitely break off the perforated section on that board to make it shorter... I didn't check the dimensions...

There is no options in the bios to enable resizable bar or above 4g decoding. To enable above 4G you need to use the setup_var method. ---The offset to enable Above 4G on my m720q using the latest bios was at offset 0xA49. To flash the modified bios for ReBarUEFI, you'll need an external tool...
