Soldered to a busbar internally is fine. Modular PSUs with connectors have an additional problem because of the resistance in the contacts (generating heat which limits their rated capacity) but also the higher resistance of the single cable over two separate ones comes into play as well -...

It's not burning that's the only concern though and there's a good chance that, certainly for short periods, the single cable will survive at 300W. The ability of the PSU to handle transient current spikes trough the single cable makes it less stable - so can cause voltage drops. Those double...

These cards seem to have very brief current spikes that could potentially knock a PSU for 6, depending on the design. Need separate cables for each 8pin connector too I would say.

Yeah I've had a play with that too. I have to say that as long as I don't use ANY monitoring software it runs rock solid at a shade under 2kH/s. I'm running my single Vega64 on an RM1000x so have plenty of head room :)

@AmateurExpert did you flash the bios to the AIO version or stick with the stock bios when you installed the block. Am swithering since many report issues after flashing....

@essentialblend Nicehash is actually a lot better now after the hack ironically. You can withdraw > 0.002 to Coinbase for free if you mine to one of their internal wallets. BTC withdraws via GDAX (Coinbase's trading engine) are then free to an external wallet or you can set up Revolut to get...

I wouldn't worry about the silicon. The pump and fan will probably die long before the HBM does :D The reason I mentioned cryptonight is that like for like it will run the memory cooler and just as profitably/more profitably than ethash. Something like electronium if you want to avoid nicehash...

I've been playing with the soft power tables and this is my water cooled air card mining cryptonight (hash is 1650-2000H/s). The same tweaks apparently work well for Ethereum too and it's certainly a lot cooler - and uses less watts - than the water block alone. I was trying to work out what's...

With CryptoNight mining the way it is right now the Vega64 is a better bet for mining that the 1080ti - ethereum is marginal but wins on equihash. Never try and second guess a miner's spending habits though. Talking of spending.... I had a moment of madness and bought the EKWB Fluid Gaming...

This is what I get on my 64 air with P6: 1602/1050mV, P7: 1722/1090mV. HBM2: 1090/950mV(just tried this as some think it stabilises things!). Because it's air I set the fan to 3318/4818 and the temp target to 73C. Doesn't crash but sounds like a jet engine taking off ;) EDIT: This is with HBCC...

My Sapphire BIOS (Reference Air) is 016.001.001.000.008730 not sure if it's worth updating? Am still on air as I don't have time to install the EK block at the moment so unless folks think it's worth updating in the meantime I guess I could wait and go for the AIO BIOS once a block is fitted.

^ This. I've had problems in the past with both 7990s and 295X2s that looked like they were borked (BSODs, black screens, crashes etc.) but on wiping the drivers and reinstalling it fixed up all the issues.

I measure 270mm from the internal case wall at the PCI-E slot to the rear of the card. It's probably 280 if you include the overhang on the bracket.

Just been doing some initial playing with my card and have noticed that the GPU core voltage doesn't appear to go any lower than 1000mV? HBM2 also appears to throttle at higher temperatures (around 80C) but just bumping up the fan to "almost too loud" (3,000RPM) keeps the GPU at ~65C and HBM2...

A crap quality photo of the bag of Haribo I got today. It came with a free graphics card that's currently in my test machine :D

Well it appears that my Vega 64 launch day order has now shipped...... will be testing it out thoroughly before ordering the EK block!

Can you not use the standard backplate, even as a stop-gap?

0.04mm is the difference in height between the core and HBM. The 0.1mm difference is between the overall height of the different VEGA packages.... means that there is a small risk of cracking the core if you clamp down a cooler designed for the lower height part.

Not sure if you guys have seen this. 0.1mm is quite a difference so careful tightening up those EK water blocks.... https://videocardz.com/72173/there-are-at-least-three-variants-of-vega-10-gpu-packages

Minimal to none. The difference will be the increased resistance from longer PCB traces.
