Stilt apparently already has a fix.

^THAT^ since it seems the IRF IR3567B can manager power delivery for each phase.

sorry folks but, truth be told the opinions expressed in that video are entirely wrong.

About the only way you are going to control this via software is greatly limiting what the card runs at, and thus probably destroying any OC potential of the product.

Either way, there still appears to be an issue with the card in how it was physically designed. While AIB should be able to address it no problem, that doesn't help the early adopters now.

there is nothing NON compliant or "wrong" about the hardware lay out; its actually the way it should be.

don't forget, according to AMD, PCI-SIG had the card in their hands.

Yeah IR3578B can split the power from 50/50 to 70/30. That's why we have programmable controllers that support all of these things along with voltage control

I am not EE but when i did a lot of lessons for circuits back on university so i am not that up to task to talk about the issue. I trust @looniam for that tongue.gif

Also do get the sticker of pcie on your box you need to pass PCI-SIG tests apparently

Sucks for early adopters. Going to wait for 1060 and AIB 480 before committing a purchase though.

Last time they said FuryX was an overclocker's dream, it was able to reach 1200 from 1050 by hard modding. This time the "dream" RX480 reached 1400 from 1266, and burned your mobo. Please, AMD, don't say anything about Vega anymore....

They didn't said anything about overclocking on rx480. just vr performance for cheap price, and the card actually does that.

it's not a big issue guys.

AMD will likely just tune their driver to pull more power from the pci-e connector rather than the pci-e slot. That would solve the problem with being out of pci-e slot spec, then they can suggest a power supply that has a certain amp rating for their pci-e rails.

A couple of days ago someone tested 3 motherboards and 2 were more expensive $150 models and the other was <$50.

The budget board crashed with every game while the high end boards ran fine.

Now someone else is using strictly 3 different budget boards.

2 of the motherboards actually ran really well but the 3rd one crashed with almost every test made except for when he played Overwatch.

I would be frustrated if I had a combination gpu and mobo where my online gaming sessions crashed mid fight. It's a big deal if you have the wrong board but with the right board it can be managed.

Problem is that AMD can't state "to use this budget GPU you must but a specific high end quality motherboard only", or "use compliment motherboard else you risk your board to go boom".

Having to limit the card in order to keep it in check even with budget motherboards, is going to be harmful for performance. I wonder how much bad feedback it is going to generate when people starts to be angry that their GPU does not come with the same performance as they were promised through reviews, once limiting drivers come out.
"My card is not running at 8ghz memory like it was promised!" or "my card can't be OCed!" or "my card isn't giving me the fps I wanted!".

I'm not going to give any feedback if the fix ends up neutering my 480's performance. Just going to quietly send it back to Newegg under the claim of false advertisement and pick up an AIB model wink.gif
