[Reddit] RX 480 fails PCI-E specification - Page 31  

post #301 of 1129
Jumper cables actually move a lot less amperage than many people think they do because of the poor connection area/pressure/corrosion. But yeah, distance is a factor.

This is obviously a new and dangerous development which has been deliberately orchestrated my AMD to destroy your computer and catch your house on fire. No one else has ever or would ever allow a card to draw more than the official PCI-E spec.

XD they are doing this so It will kill all those Intel cpu and buy zen for their next upgrade

I got a newer example for ya then wink.gif

Gigabyte GA-F2A88X-D3H. Has PCi-E slot power "+10%" and 3d01 performance boost in the UEFI.

board performs like crap though, has some serious issue somewhere restricting either the cpu or video card. I dont know which as all i know is that the frame rate with it is always crap no matter what you do.

Joules Watts is the measure of instantaneous power.

A watt is defined as 1 joule/second, so it includes a time dimension.

Still, "watts per second" is wrong, but the same argument *might* hold true if interpreted as joules/second - or, simply, watts tongue.gif

Who could forget the legendary DFI LanParty NF4 boards?. Heh speaking of NF4, how many people here even know nVidia used to make some of the best chipsets for AMD platforms? The S939 days were the best. It was exciting back then seeing all the people breaking WRs and trying to push everything to the limit. Everything is so boring these days with boost clocks and modern processes that clock to the moon without any effort.

DFI is still around by the way, but they only make industrial boards now. It's a shame Oskar Wu, who was responsible for the LanParty's crazy tweak-ability is just making boring industrial stuff now.

So from what I see- drawing more than 75W from the PCI-E won't be helped by adding an 8-pin or a second 6-pin. That's kind of ridiculous to be calling that the magic bullet. Now that the TDP of the card exceeding 150W that would be in-line with the sole 6-pin connector usage would be fixed by that. However, I don't see the TDP going up, it sounds like there's a software/bios error, issue, or a user-side problem with the software or their rig. I don't see the reference models getting a second 6-pin to be 165W, the opposite seems more likely to me. The excessive PCI-E draws sounds like it's going to need a different fix since it'd still be drawing too much with an extra couple pins or connector.

The idea that nobody would consider a $250 card that doesn't use a good power supply seems very strange to me. With power supply failures having such dire results it seems odd that anyone would want to cheap out on a power supply rather than a gpu- that just seems dumb. With my good GPU coming out I intend to build another cheap one, don't plan to skimp on the PSU for that either. When I built my PC I didn't spend a fortune- it just didn't look like the NVIDIA offerings in the price range would be better. I also find it funny hearing "well guess I'm going NVIDIA this go-round" or "looks like I'll have to get a 1070". The two aren't in the same league. Maybe the 1060 will be but what'd the 970s launch at? If the 1060's closer to this performance will it be reasonably priced and will their stocks be available even? Now sure, a pair of them's got similar performance competitive with a 1070 but I guess I just find it hard that this could be the straw choosing to go single NVIDIA next-gen over crossfire AMDs. Your single-gpu considerations in the same price-point as the rx480 are last-gen currently.

I got one. Seems like a good card for the money with 8gb, seated firmly between 970 variants and between the 290s and the 390s. I plan on getting a second later on after the board partners' come out to crossfire them while upgrading to a 990 board that can crossfire much better. Personally I think the issue is AMD's software or the people using it. They hardly have few problems with it.

I'd be kind of surprised if they don't do something like the 295x2 out of this- the ability to outdo a 1080 or 1070 for a touch less seems like it'd have good traction for a stopgap prior to VEGA. However aiming firmly at what they say is the main market price range and putting something very worthwhile in it seems like a very good move. Sure, it's competing with last gen NVIDIAs, but so will NVIDIA's entrance to that price range. The bottom-line is that they really weren't competitive without massive price gaps. it really seems like. That's the path they've been treading a while and the way I see it. This seems like a firm step in the competitive direction.

Guys I've been running benchmarks on my Sapphire RX 480 8GB with a 5 year old mobo all night and nothing even close to alarming has happened. Power and temps have both been in comfortable ranges. Either I'm a lucky one or this issue is largely overblown.

I think it is clear that this card needs at least a 8-pin on it.

EDIT: Not bashing AMD, but then they couldn't claim the TDP that it is rated at. rolleyes.gif

What's really sad about it is that 90%+ of the people who would buy this don't care if it's 150W or 180W - same-same to us. And, on top of that, we'd all prefer a little extra headroom - so an 8-pin connector would be seen as a feature.

The design of the RX 480 has a few serious flaws - some serious bottlenecks. For starters, they should have had at least 2560SPs - don't use all of your SP improvements towards reducing the number of SPs, split the difference in the very least. AMD should have already learned that larger GPUs operating at lower clocks is what makes GCN most efficient - so they would have been better off with a 900Mhz base clock, 1.1Ghz boost, and 2816 SPs. When people pushed it and could hit 1.3Ghz they'd be stunned, rather than disappointed.

But then it would be clearly below the 970 and 390 in benchmarks and they'd only be able to charge $169 rather than $199 as a base MSRP?

But these cards are for mainstream users who don't really have the knowledge of such things.

The single 6 pin connector attracts the customers that have cheap and shoddy prebuilts etc.
