"OGRE-250" .67L OCuLink eGpu module, using HDPlex GAN 250w

[Alucard]

My tests are from testing in Timespy with the b660i board and comparing m.2->Oculink performance with x16 performance baselines, where I had some results within margin of error. However there are a few tests done by other sites which are good starting points also:

General observations:
1) Lower tier (slower) cards benefit less from more pci bandwidth
2) The higher the resolution (the lower the FPS) the less impact of bandwidth

Scaling for 5700xt:

PCIe 4.0 and PCIe 3.0 - Difference between x8 and x16 with the fastest cards - Where does the bottleneck begin? | Page 7 | igor´sLAB

Especially after the tests of the B550 motherboards, the justified question about the problem with the split PCIe 4.0 ports naturally arises. PCIe 4.0 with 16 or 8x connection should not show any…

With a weaker card (up to ~RTX 2080) there is potentially less than 1% loss between Gen 3.0 x8/x16

Here we have 4.0x4 and 3.0x8 within ~6% of 4.0x16.

Thank you but I was specifically asking about Gen 3.0 x4 vs x16. (Deskmini x300/RX 6650XT)

Somewhat limited data but I do have something for you:

Here is the best result timespy gfx score recorded on the x300 with 5700g, ddr4000, 3060ti, using Gen 3.0 x4 Oculink: 12,415

msystems`s 3DMark - Time Spy score: 12376 marks with a GeForce RTX 3060 Ti (GA104)

The GeForce RTX 3060 Ti (GA104) @ 2040/8013MHzscores getScoreFormatted in the 3DMark - Time Spy benchmark. msystemsranks #1753 worldwide and #50 in the hardware class. Find out more at HWBOT.

hwbot.org

On a 13600K ITX system with DDR5 6600, I recorded timespy gfx scores of 12,700 average (with both Gen 3.0 and 4.0, virtually indistinguishable).

12,415/12,700= 97.7%

Timespy may not be the best indicator of actual gaming performance but I don't have any other benchmarks to reference

This is enough information for me. Thank you very much!

How'd you go with the 500W version? Or did you abandon it for now?

 

[Superghetto420]

Bro you are literally amazing . I have been looking at the one dock but this is perfect. I like the setup you made thanks a lot for sharing this.

 

[Superghetto420]

msystems.... You said that if any of us were building this you would put up something more in depth. I am building this and would like some more information especially when it comes to the way you jumped two wires. I really appreciate what you have done. I will definitely show you what my build looks like after I am done.

So you have 3 wires to make it work.

Riser power - since the riser has sata input, this is a standard sata power connector pinout on the riser side and its wired to the hdplex 4 pin sata area according to the hdplex schematic.


Gpu power - this is standard 8 gpu pin straight cable according to the hdplex schematic


Psu on - the blue and green wires in the picture. Its just a piece of wire shorting "ps on", the two top control pins to force the psu permanently on. A small jumper, like cmos jumper style, would do the same thing. It turns on as long as its plugged in. If you had a latching switch, you could put it between there to control on/off function without unplugging it. Again see the right side of the hdplex schematic for the details of these little control pins which are little tiny pins recessed to the right of the 24pin

Respect! Thanks for the reply I do not have a 3d printer so I am having it made through a local shop. I appreciate you thanks once again and I look forward to the day when you decide to do the ogre500! Once again thanks!

Another question just in case.... I am going to use a 3060 TI FE and I was wondering if it would be safe to use the Sata power setup that you have used for your EVGA? I am just making sure before I start a fire or ruin something lmao

If it has a supplementary power connector you should be fine. nVidia cards are usually fairly conservative with the amount of power drawn from the slot.

I used the hwinfo64 looked at the PCI and it said max was 43w max when playing mw3 so it should be good I think

 

[Superghetto420]

Ok so I have built the OGRE250! It's amazing.... The only question I have is how do I keep the Plex from falling out of the bottom? I noticed that msystems has a different bottom on his HDPlex?

You need to attach the base plate which comes with the GAN, then it will slot into place

i´m building this part now my self.
if someone whats to follow, here is my thread.

EGPU HDPLEX 500

Dear all, I’m new to this part, have some experiences with PC, but not so deep. I can across the ogre-250, and was impressed by the idea, but with the HDPlex 500, I think there are more possibilities. my question is about the 24 pin ATX connection, if you connect that to an PCI connection...

The Taobao seller has started to develop a solution for, small cables that bring the Oculink connector off and away from the device's m.2 riser (often located in an inaccessible place) and able to be placed into an accessible place with some modding.

So far, the following customized cables are being made: Thinkpad series 14 and 16, Acer Shadow knight, Asrock DB9 port, GPD WINMAX 2, and a few others which don't have specific hardware associated with them.

With all of these though, the host device still has to be modified to place the Oculink connector in an open position.

I believe they are open to engineering new versions for basically any device. It's possible one of the existing versions might work for Steam Deck if someone wants to try (the riser could be cut down to 2230 length).

Any link where can I buy this? Thanks!

Product link doesn’t work anymore but I used this one for my DeskMini, took the VGA port off and swapped this in
