There is a update for msi afterburner which allows the memory to get to 3000 alternatively use GPU Tweak 3 and enabled extended overclocking feature and will allow you to get to +6000 / +3000ab . The voltage bug is fixed with the must recent hotfix driver 572.75 but you do lose a bit of performance on that driver, best for benchmarking is 572.47 but need to use the work around I posted on Overclock.net to get voltage working...

Cheers! I was looking for that workaround. Tried it and it works.
GPU Tweak v1513 seems to allow +3000 on the memory.

I understand they show the over current in red but it's actually pin 5 that's the culprit and not making good contact

Yeah, I tried reseating and now it's pin 3, not sure what's going on.

Even worse I tried the original cable that came with the Rog Loki 1000W.


Think Corsair uses those leaf spring connectors that make better contact.

2billion transistors on a die, no problem. Two pieces of metal that reliably touch, nope.

First image is the stock Corsair SF1000 (2024) gpu cable. The second is a custom from Moddiy.

Scary as I had the Moddiy cable in my build for months running past 600W.

Yeah moddiy if I recall was what that guy on reddit used when his connector melted, imo I've got a cable mod cable and it works flawlessly, so it's probably that brand I'd avoid. Have you switched out to the 4x8pin adapters?

Annoyingly the Rog loki doesn’t have enough 8 pin pci-e cables to use the adapter.

I’ve put it back on the test bench for now. The SF1000 seems to work fine.

Tight fit but managed to get it in an ITX case. Exhaust fan as the top almost touches the GPU.
