Status report on the RTX 4090 (X-Vsion model)

Boot test conducted on the P570WM: A Quadro P5000 was installed as the master and the RTX 4090 as the slave. Although the system booted, the card was not recognized in the BIOS or Device Manager.

Boot test conducted on the P775TM1-G:
The system booted, but the screen remained black.

The modified heatsink and FPC cable required for use with the P570WM could not be used, as they are currently located at a warehouse on the mainland.

You need to use them. It was obvious you'll get a black screen.

もし400ドル払ってくれるなら、もちろん買いますよ。RTX 30XX/40XXのヒートシンクは全て売り切れましたから。 

 

ヒートシンクのCADファイルと回路図は入手済みです。Cicichen社では対応できなかったため、Ythermal社に問い合わせました。

 

5090との互換性は不明です。5080は4080/4090と同様に動作する可能性があります。

It is said that the RTX 5090's compatibility with the P570WM is unknown, but if it were to work, would it be usable only with an external display rather than the built-in one?

Hello.

 

I brought the modified heatsink, FPC cable, and X-bracket from the mainland warehouse. When I try to fit them together, the holes on the heatsink and the X-bracket do not align.

 

Also, I haven't applied a thermal pad to this heatsink. Would applying one resolve the issue?

Mine v1 fits, try again. I have it on my P570WM3 installed right now. You need to use 1.5mm thermal pads for the VRAM. I was selling v2 but they all sold out.

This card and the heatsink aren't a match.

 

If you try to fit them together, part of the heatsink gets in the way. You'll have to shave off a section of the heatsink.

I haven't tested these while installed in the P570WM. Mounting them in the unit might solve the issue, though...

You use them without thermal pads... With thermal pads, it fits.

 

You also need to modify your fan mounting as the factory for the v1 didn't respect my needs.

 

V2 fixed the mounting but I sold them out.

 

I sold 4 v1 and got 0 complains tho.

Given that there are no complaints from others, I simply ended up with a defective unit.

The factory likely didn't test-fit the part against the actual card—instead manufacturing it based on SuperMG's blueprints—and I just happened to receive a unit with a slight misalignment.

Since there are no companies in Japan that will modify metal parts owned by private individuals, I plan to file it down myself. It’s only off by about a millimeter, so I think I can manage it.

 

I do regret not buying the Heatsink V2.
