Sold my Z890 Apex and 285K to @win32asmguy Paid for and shipped to them this afternoon.

Rocking my 1600W T2 still. Dual 4 8 pins to 12v2x6 connectors from cablemod. Works flawlessly. should have sold you my spare apex and 285K lol.

My Suprim Air is the better card with 800w Matrix vBIOS, but the 5090D with HOF XOC vBIOS is great too. I got all of my water cooling parts together, I still need to block the card lol. Just been lazy. But the Matrix vBIOS just had something special and it's a better sample chip. But at 800w, I was feeling the cable and it def felt warm, but not sure how much that means. But having the dual 12v2x6 connectors does make me feel good and not have to worry about the cables melting, at least in theory. So I guess I'll daily my Galax card in my main rig, and the Suprim will stay in the living room setup. Honestly such an overkill card, but after I saw the Matrix vBIOS, I wanted to dump that TUF 5090 so fast. Now lol it could have had the XOC, but I still think the Matrix is best for daily. Lots of words, prefer the Suprim card, insane cooler, Matrix vBIOS with 800w is ideal, and +4000 mem isn't really useful TBH. But peace of mind with the dual cables has me wanting to stick wtih the HOF, plus it's super unique. I also had a 5070 Ti Prime but sold that last week too. So 5090s it is until I get bored again. I really do need to put this HOF under water though, ASAP. Especially with the cold days coming this week, I could try and push the card. Maybe go outside and bench in the garage lol.

Very nice for your Astral LC card! Hilarious that magically Asus can release the XOC vBIOS after the Matrix made their entire 5090 line (except white Astral) complete garbage overnight lol. Good to see them realize most will never flash this vBIOS and it's only the very enthusiast community so risk is tiny.

Damn, scammers now running scams through BB. That is just unreal, I hate people lol.

Very curious if you can flash it and see if it works on your suprim air card! Apparently it doesn’t work on the Suprim LC card which is wild. Must be a fan controller issue?

They fact that they used basically the best memory option 6000 CL30 for the AMD part, but then use far below Intel's optimal spec is enough for me to call it biased. Even if you use a mainstream 4 dimmer, most can achieve around 7600 CL32-34. Hell even using 7000 CL30 2x32gb dual rank would be a better option as it will offer up gaming performance of an 8000 SR kit on Intel. Unfortunately, this type of testing is mainstream and how most outlets test. It is what it is, I've just learned to ignore most of it.

Had they just gone with 2x 12v2x6 connectors, it would have been worth it for the niche market IMO. They would have instantly sold out. Nobody really wants to have to buy a BTF board, at least on Intel side and have worse memory performance over the 2x DIMM OC boards. Maybe next gen will have BTF on 2x DIMM boards, but that is a gamble and who really wants to wait. This entire gen has been a mess. I got my waterblock for my HOF XOC card from Ali delivered this week. I still have not gotten the rest of the parts but plan to have those soon and can finally put this bad boy under water. In the end, I think I'll still perfer a good air cooler. But given the recent news of 2027 for RTX 6000 series, I will at least get to get some use out of the setup before it's obsolete lol.

The stock voltage is 1.15v and the stock power is 600w. The XOC vBIOS is publicly available on tech power up and is 2001w, which further unlocks voltage and memory another +1000 over other 5090s. Some nice individual over at OC.net PM'd me the extra special HOF tool for even further voltage, LLC, and switching period control. Basically the same as the old KingPin tools. Ordered the HOF 5090D IceMan waterblock on AliExpress. Figured the card is pretty rare and any future owner will def. want the ability to put it under water to take advantage of the voltage and power limits.

I tested the 100% fan speed button on the backplate and funnily enough, it's not actually 100%. It's 200-300RPM slower than using 100% fan speed in Afterburner LOL. So the hardware solution is slower than just setting the software to 100%. Super odd but not a big deal either. The backplate looks very similar but zero thermal pads, and instead has this plate protective shield over the entire backplate except on the backside of the GPU die which does have a thermal pad. But the rest has no thermal pads on the backside VRM which makes absolutely no sense to me. I guess I'll buy some thermal pads and removal the shield. I assume they did this to prevent shorts with the backplate, but the thermal pad should provide adequate gap that the risk would be near zero.

Thank man! Unfortunately until first week of Nov I won't really be able to mess around with the card. Found a waterblock for the card on Ali Express, as I understand they are super rare. Guess I better just buy it as there are only 5 remaining in stock. But to truly max out this card's ability, it needs water. On air I'm able to push 700-800w max before temps become insane. The other thing I've found is the memory temps, even at stock are pretty terrible at around 74-78c. When I push the card they can hit 84c. The cooler itself though can manage to keep 700-800w in check with core temps in 70s, which for an air cooler with vapor chamber is decent at that power draw. I think my TUF OC 5090 card hits around 70s at 600w. They used this *mostly* closed off backplate, and ZERO thermal pads. Instead it has a heat shield? So it essentially traps heats in to the card. Makes no sense. I should probably remove the shield and do thermal pads to try and wick heat off the back of the card. The card did have PTM, I took it apart to PTM the card, and to my surprise, it already had PTM lol. But the tinkering let me take it apart, which thankfully is quite easy and they use same size screws for everything on the back. The VRM is just ridiculous on the card. 36 phase VRM.

5090D is only Galax HOF available. Only 100 of these cards were made. I got it for about $800 over an Astral. Which in hind so hindsight is still a terrible deal lol. But at least it’s semi unlocked and can go to 36Gbps memory. Can you DM me the Galax HOF software? I want to see if it works on 5090.

Sometimes I feel like I make the worst decisions. Found this card brand new from a small shop in Florida.

They were shipped and sold by Amazon.

I have the TUF 5090, and it's a pretty great card. No issues to report. I wish I had gotten it at this price!
