*Official Benchmark Thread* - Post it here or it didn't happen :D

[Mr. Fox]

This is with the Astral 5080 XOC vBIOS. It totally exhausts the 450W power limit (pegged to 450W on the WireView Pro). I've ordered a block for it and will shunt mod it. One fan does not run so it is getting too hot and thermal throttling, but the software works great for the tweaks.

It does fantastic with the stock vBIOS but I have not had time to research or test one with higher power limit. If there is one you suggest give me a link to which one (or upload) and I will run some tests on it. I just ordered a Bykski block for it on AliExpress for $200 ($75 less than from Byski.us) with free shipping.

 

Bykski Armored End Port GPU Waterblock Gigabyte GeForce RTX 5080 Gaming OC 16G (N-GV5080GMOC-X-V2)

 

Here is a 12-loop run of Steel Nomad usng the stock vBIOS. About 10 loops in I installed the side panel and the GPU temps dropped by 2-3°C so the max temps would have been that much lower than HWiNFO64 is showing. 

 

I used Asus Astral 5080 vBIOS before since it has a 450w limit on the MSI 5080 I had last year for a bit but all three fans worked. I'm going to end up flashing it again on the SFF OC like yours. That and Melon should open them up like a beast especially yours on water so a fan not working won't be an issue for you.

 

I wonder if a different version might wake up the non working fan since there are three variants floating around for the Astral 5080 (Black, Noctua, White)

latest version now supports profiles, profile set at logon, V/F curve editor and other UI tweaks.

 

i did a quick check last night, both Xbar and GPU Core Voltage adjustments work flawlessly on the fly, same with Clock offsets for Xbar, Core, vRAM. like....no need for anything else anymore, really 😄 

 

The tight knit community is alive and well. Crazy how enhancements and QoL are being implemented Fast and Furious.....

Maybe another variant would wake up the non-functional fan. This is the XOC 450W vBIOS I use on the Prime 5080 and all three fans work. The one not working is near the I/O so that is a more critical fan being close to the die and VRM. But, it certainly will not matter when blocked.

Absolutely. I have hated having to use the EVC2 for voltage control. It is a cool mod from a hardware geek perspective, but a real pain in the butt to have to implement, and we should not have to. All GPUs should function like a K|NGP|N or HOF GPU. I'd love it if we could get the power limits unlocked (adjustable) or simply removed (increased to something more than the GPU can ever pull, like 5000W) using software to avoid having to shunt mod. The risk involved with that kind of geeky fun (and loss of warranty) loses appeal when GPUs cost two to five times what they are actually worth. If it is done with software, there is no way to prove or enforce a warranty that excludes overclocked hardware that fails for reasons that have nothing to do with overclocking.

This should work. 450w from Aorus, should make all fans work and has a higher default boost. 

 

If not maybe Gaming OC, same 450w but lower boost by default.

More garbage for less money. 

 

[Mr. Fox]

Well, it seems the 12VHPWR fuses are blown on my 5090. I was launching Steel Nomad with a heavy overclock and the card turned off (red light for 12VHPWR came on). I checked the three fuses for the 12VHPWR with my mullti-meter and all three are open. So, I ordered new fuses from Mouser. I am going to add a 4th fuse  to the open solder pads for F1 that Zotac did not populate. That should take it from 720W fuse limit to 960 with the 4th 20A fuse. I checked the output side of the fuses against ground and there is no short. I think the massive power spike lauching Steel Nomad was just too much too sudden. In one way it sucks because it is very inconvenient, but in another way it is awesome that they did exactly what they are supposed to do.

 

This will give me a reaspm to test my new soldering tweezers. Should be (hopefully) fairly easy to replace them.

Basically a stack shift to shoe horn in a very poor card where a 9060 should go while those former prices have all shifted up and will most likely continue to shift upward.

 

This card is bad for the price. If it was $199.99 it suddenly becomes an ok budget card but $280?

 

And this was the 8GB version..... I can imagine the 4GB version is just going to be extreme trash versus just normal trash on this one.

WOW......I mean I'm glad to see the fuses doing their job but damn.....

 

Hopefully this will be a quick and easy fuse swap and upgrade, but yikes.

I am actually kind of surprised they have not already blown the way I have pushed this GPU for benching. I've run way more than they should have allowed me to, but Steel Nomad is famous for the massive power spike in the first couple of seconds and I think that experimenting with the 2000W vBIOS together with the shunt modding was the straw that broke the camel's back for the fuses. I normally have used a 800W or 1000W BIOS.

pretty cool, couldve gone 50 other ways straight to gpu melting hell instead 😄 

[Mr. Fox]

Confirmed only blown fuses. GPU is totally fine. I bridged the F1 fuse solder pads with a wire for testing and it's good to go. Now I just need the fuses and we'll be back to normal +1 fuse for extra capacity.
