Hey fellas, commenced on more testing for getting Dual GPU's running on my ITX system. Long story short; on X570, it failed all attempts. Short story long - I was able to get both GPU's to post once I got longer PCIE extension cables but was unable to get a game running and every crash I was essentially starting over with getting the system to POST. So PCIE x16 to x8x8 remains illusive despite the BIOS supporting it. This method has been formerly put to rest for my platform. I did fall back to an NVME to PCIE x4 and tested with the RX 6500 XT which did prove successful. This type of solution would work fine for 1080p and maybe 1440p however 4K120hz HDR requires PCIe 4 x8 to be functional, not to mention a beefier GPU. Sadly this means that Dual-GPU Frame Generation for my AM4 system will once more go on ice. What I am thinking of doing is getting another 1080mm radiator and refocusing my efforts towards benching. The current scenario with the A/C, particularly where the A/C vents cold air relative to the where the rad sits is inefficient. A lot of cold air is currently being wasted. The idea I had is to create a "box" right outside where the A/C vents, then the 2x 1080mm rads would "exhaust" that air into the room and any leakage would either fall down to the systems below or not be significant enough to matter. Anything interesting I should consider adding to this loop?

25 bucks is honestly not much at all, especially these days. Perhaps I would be more inclined to pay that given I know some of your history and how high of standard you set for whats acceptable, let alone whats considered useful for benching. If you decide to give it away for free or charge w/e price you want that choice is ultimately yours. Anyone who skoffs at that can honestly kick rocks. In fact it pisses me off at how lax the moderation is over there as discussing pricing openly was always against their TOS unless they changed it. The whole thing reminds me of the type of person who would spend 5 grand on a pc only to re-use some long retired ratted out power strip and complain about it catching fire. Honestly dont regret no longer surfing those forums.

Im pretty sure the PCIE lanes to the CPU remains the same at 20 lanes but you can get more via chipset (albeit, slower and shared) Still, looking forward to how this ends. Might even sell all my old spare parts to consolidate into a P870 chassis

I havent seen a single device running via two MXM slots before. I understand that x8 makes sense since its a consumer level chipset, likely 20 lanes if I had to guess?

I know everyone is getting excited, but please keep the double posting to a minimum. Curious you are using both MXM connectors?

Of course, its not something I would recommend to the laymen. Just something I have been fondly passively following for the past couple of years. Mods are always exciting when you are watching someone else suffer the ups and downs. When I was modding the Alienware 17 R1 my friends thought I was nuts taking a Dremel to my laptop and "making" my own heatsinks and there were definitely plenty of times I was questioning whether or not I was tempting fate! lol Like an idiot I did it anyways. The Red Devil 7900 XTX effectively is that new scratch to that "itch". Heck I have been semi debating picking up a DDR3 based system just to see how it performs under games of this era. I have enough hardware though so I really shouldnt. https://www.ebay.com/itm/406231132612?_trkparms=amclksrc%3DITM%26aid%3D777008%26algo%3DPERSONAL.TOPIC%26ao%3D1%26asc%3D20250417133222%26meid%3D3b5d9c1dce2a42bca896f1dd563e6c62%26pid%3D102727%26rk%3D1%26rkt%3D1%26mehot%3Dnone%26itm%3D406231132612%26pmt%3D0%26noa%3D1%26pg%3D4375194%26algv%3DWatchlistVariantWithPSItemDR_BP%26brand%3DASUS&_trksid=p4375194.c102727.m162921 If they accepted 300 might be a fun deal, looks like a lot of cleanup though. As for the politics, lets steer it back away from that. Feel free to discuss the issue itself but lets leave the politicians off the thread. Feel free to continue via PM :)

Tried Bifurcation again today and sadly no dice, system would hang half way through post. Oh well, I'll return the adapters at some point during the week and hang up this goal for a while. Likely going to need that adapter from C_Payne in the UK. Otherwise I want to get more hoseline and make some adjustments to my setup and the benching itch has been working me over for a while now. Maybe I'll start with the EAH4890 and potential Tri-Fire.

Just realized you cant see the connector, its definitely PCIe 2.0 sorry about that lol The 5700 XT gave him a 100% boost in performance and double the VRAM. I just needed something else that was "newer" mainly for the HDMI 2.1 connector. The card may not be able to handle 4K Frame Gen but didnt want to buy anything until I could figure out what works for me. Gives me something else to submit into hwbot also I gave up the 3090ti for FG, installing the drivers for both vendors is such a huge headache and Microsoft likes to muddle with settings without user input. Keeping to one vendor should eliminate that hurdle but i'll know more tomorrow when the 100mm ribbon arrives I traded one of my Gigabyte 3 fan 5700 XT's for a 3 fan Gigabyte 6500 XT. Cant recall the last time I used a GPU that only had 2 I/O ports outside of maybe laptops.

Couple of new additions to the roster. Traded one of my 5700 XT's to a coworker for his 6500 XT. It'll act as my frame Gen mule on the TV and main gaming monitor. The second was my first real GPU. Anyone care to guess what it is?

The vBIOS was modified and did report 16GB but failed any test plus didnt output any direct images from the GPU (guessing iGPU was used for trial and error) I think, sadly, this is more of a Nvidia was entertaining the idea of 8GB and 16GB variants back then, deciding only to release 8GB variants versus AMD who never entertained 16GB consumer cards. In theory it the GPU is compatible since the workstation variant exists with 16GB but there may be significant differences in the PCB. Since RTX 30xx continued its dominance, we lost innovation since AMD couldnt hold Nvidia to the fire. I really enjoy my 7900 XTX and how much I was able to extract out of it. Stock OC vbios: 2565 Aquas OC vbios: 3Ghz 24/7 Highest OC: 3300c That being said it'll never beat a 4090 with the same amount of time put in.

I actually REALLY want to do this...for my RX 5700 XT's. I still have 3 of them and last time I used one it immediately hit 8GB VRAM buffer in Sons of the Forest :( Sadly there are no success stories of anyone doing this for that card. I continue to hold out hope, maybe I need to setup a bounty for it to generate interest? Not sure how I would even go about it. Especially considering Lossless Scaling Dual GPU FG, just need one card that has the 16GB VRAM and the other could be left as is. I keep revisiting the old reddit thread where one university student tried it, looks like it failed and/or lost interest due to lack of time. Would be a lot of fun going from 8GB 14Gbps to 16GB 18Gbps + OC. I hold out hope but gotta admit its disheartening not seeing any progress made towards that end.

If you think about it from the inside out there is no reason to bin anything at all for quality considering the current market forces in play. I'm sure the cynical outlook might be that they are binning server gpu's and we get the left overs. I doubt they are binning anything at all for any interested party since the demand is so fierce and prices making all the shareholders quite happy. I was thoroughly surprised to see that my 3090ti was numbered and also tested for its clock speed which was written on the frame of the GPU die (#1479 and 2055 if memory serves). I'd be lying if I didn't entertain selling the thing an extra 1200-1300 is a fair bit of spending money. Decided against it, plenty of uses for a 3090ti. Pretty happy that I was able to find an unused ek-wb for it they should pair up nicely someday.

Maybe someday I can be bothered with Memory tuning, but its not going to be today, or tomorrow, or the day after :) I enjoy overclocking to yield tangible gains in gaming. Looks like PCIe Bifurcation works on my Aorus ITX x570. That being said I had to scrunch up the ribbon cables so much for the test that I think it was rendered non-functional. The 7900 XTX wouldnt show up at all and the 3090Ti was misbehaving quite severely reporting the link at PCIE 2.0 But it POSTed! so thats progress of a sorts. Got a shorter ribbon (60mm) so hopefully that works i'll test this weekend.

Quite right, the fans location prevents MXM 3.1b cards from being able to fit traditionally. I may have to go the MXM to PCIe route or something more extreme if I want to keep using the platform. Finding a decent 1:1 component transplant doesnt seem to exist though :(

I have a T14 for work, it mostly gets the job done fairly well.
