Andy has issued a statement regarding potential excessive power draw through the PCIe bus for its new RX 480 video card and that includes the reference models currently shipping this coverage is brought to you by origin pc and a new origin kronos gaming PC with the RX 480 is customizable upgradeable and ready for VR to recap everyone very quickly the reference model has 16 pin power connector those are rated for 75 watts but they can draw more depends on the power supply the cable things like that and it's also drawing the rest of its power through the PCIe slot this is normal the PCIe slot is generally accepted and rated for a 75 watt power draw it can be exceeded it should not be just kind of as a general safety rule for the motherboards power management but the RX 480 is exceeding that limit especially with overclocking and to give you an idea of that when we overclocked this one which is a liquid-cooled RX 40 that we built we were hitting a 192 dot to watch GPU power draw and that's for the GPU that's not the board the board power is an additional 40 watts or so from the memory and other board components and then that increases of course as you overclock and really stress a fixed clock rate new increase the power target things like that so we're looking at a range of 222 250 watts in our overclocking depending on what we're doing so that's a lot of power for one 6-pin to handle that means a lot of it's coming through the PCIe bus so aMDA has issued this statement regarding the issue they said as you know we continuously tune our GPUs to maximize the performance within their given power envelopes and the speed of the memory interface which in this case is quote an unprecedented 8 gigabits before gddr5 recently we identified select scenarios where the tuning of some RX for 80s was not optimal and we can adjust this tuning via software basically is what they're saying and they're looking for a driver to fix these issues so first of all I want to point out that a gigabits per second is not unprecedented just kind of get that out of the way marketing speak but the core of the matter is not about the memory speed it's about the power draw and so this discussion of doing driver updates to tune down the power draw what that translates to very likely is a throttle as we demonstrate this in our how to overclock the RX 480 video which should be on the channel now or very soon and what you'll see is once you've begun pushing the clock rate if you haven't touched the power percent target so if you're not moved up to an additional fifty percent power the clock will actually throttle itself and very rarely if ever reach the targeted overclock value so you could type in fourteen hundred megahertz but it may never hit even 1380 or 1350 based on the power drug is already choking on power so you can fix that buddy by increasing power target fifty percent but a drier update potentially throttling that back would I think be a potential limiter to the clock rate and therefore fps and performance and frame stability but we will test this separately once the new driver or whatever it is comes out I bought this card out of pocket this is an RX for 80 reference cards so what is this at one point but this is a reviewer model this can actually do a couple things that these camp like switch between four and eight gigabytes for testing this is fixed eight gigabytes it is a card you can buy off the shelf yourself I will be testing this one to see how it is affected by the driver update and we might validate on this just to make sure things are looking good but that's all for the update basically and he knows about the issue they're looking at the fixing it and it's a driver update so people who already bought these will receive that update and it should help with cheaper motherboards things like that which may be threatened by the overdrawn PCIe but otherwise we'll have to look into the frame rate performance so as always thank you for watching patreon link the post real video fiona helps that directly subscribe for more content and we'll be looking at some other not our x 480 things very soon so do check back for that i'll see you all next time
