Rx 480

Hey guys,

I'm going to get the Rx 480, anyone else? I hope it works well with Beam.

 

Don't: https://www.reddit.com/r/Amd/comments/4qfwd4/rx480_fails_pcie_specification/

 

While it's 100% true it happened on NVidia side before and it's not a big deal. It's still safe. Even some OCed 1070 and 1080 can drain around 300Watts so also around 100Watts from PCI E slot, still not a big deal. Actually 8pin is just a 6pin with 2 grounds, not more 12V wires. But even low quality 6pin is able to output more than 200Watts, so 100% fix is easy, AMD have to force 83% of current to flow through 6pin connector and you are 100% safe to do 4 way Xfire Even if they won't do that you'll not combust your MoBo and if it's old and cheap and you don't have good quality PSU it will be crashing or doing BSODs at most. Yup it takes more current than AMD have said it's bad, so big minus for them for lie.

Well RX 480 should perform good it's ~44% faster than previous gen (R9 380) and ~59% faster than previous gen NVidia's R9 380 competitor (GTX 960) FOR THE SAME RELEASE PRICE and both handle BeamNG fine at medium/high depends on preferences.

 

The problem that MOHAAPlayer mentions only happens with the reference design, so custom versions from brands like MSI, Asus, Gigabyte, Sapphire... won't have this problem.

The problem: PCI-e x16 provides 75 watts and 6-pin provides another 75 watts. Unfortunately the reference design forces the motherboard to output more than those 75 watts causing some motherboards (those with Z97/Z170 chipsets don't have this problem) to freeze, shutdown or damage the mobo.

The custom versions won't have this problem because they will take more watts from the 6-pin and 8-pin connectors than from the pci-e slot.

 

Only 1 NVidia card on a custom PCB has ever been reported to exceed 75 watts from PCIe, it is also not remotely safe.

there are no custom versions *yet*

also basic electronics guys, you dont necessarily get full control of where power comes from, they wont be fixing that in a BIOS update

 

Well I'll be buying a custom one, with more GPU Power connections than the one 6 pin VGA. I think it'll be a good card.

 

when customs hit yeah they should be great, might even be enough to break my green loyalty

 

Please explain to me why I'm so hyped about the 490 and 1070?

 

False, false and false. More than 1 NV card had this issue, it is safe, and it's possible to fix current flow by BIOS, RX 480 have more phases than GTX 1080 have, but to be honest there's really no need to. Btw by undervolting it is possible to force it to not throttle ( so it stays at 1266MHz ), stay a bit cooler and consume less power, moreover you can set it to works rock solid at 1,3GHz and 2050HMz on memory.

 

Name 1.
Also basic electronics, VRM designed for 75W exceeding 75W, dangerous. Basic electronics, you dont choose where electricity flows in software.

 

No, it isn't. It will damage components on the motherboard and can potentially cause something to explode or cause a fire. It's the same reason you've got warnings on light fixtures not to put a bulb above a certain wattage in it. The fixture is only designed for that wattage, if you go over, you have a serious fire hazard.

 

Do you seriously think an electronic part will get destroyed as soon as there's 1W more than allowed going through it? If the motherboard is decent, it'll get along with almost 100W. Of course, if you're "that guy", who always gets the cheapest one, you're going to have a problem. I don't think your GA-H110M-A explode even if there's 90W going through it.
Sure, it's a bit dumb for AMD to make that mistake, but it's less dumb than say build half a gig less well-functionig VRAM in it than it says on the box.

 

So, why we don't have waves of failing mobos after OCing 750Tis? Why nothing happened with 950 without power connector after OC? Even OCed GTX 960 STRIX? There are examples of AMD cards after OC too, but just to show how wrong you guys are. Nobody's mobo failed because of RX 480, they just lie, want to fraud money from broken mobo they have or just to made AMD looks bad. First of all 10% of tolerance = 82,5Watt is minimum what mobo have to be capable of continuous output. But that's extreme case MINIMUM, and HAVE TO BE a bit higher. This standard was for cheapest mobos with PCI-E 1, but nobody is using them now, well if somebody with PC worth 100$ is going to put there 200$ GPU, his problem, because everything will bottleneck this GPU and it will stay way under max. load. Any a bit more expensive mobos even with PCI-E "1" can easily output more, but in worst scenario it will reboot or jump in to BSOD. Actually there are cards that consume at peak power over 220Watts just from PCI-E socket, nothing happens. Reference non OCed 750Ti in ~35% of time stay above 75Watt up to 140Watt peak, what will happen if you'd OC it even 2-3 %, what if you push it to the limits? It will look worse than RX 480. Peoples who were buying 750Tis probably bought cheaper PSUs and MBs than potentially RX 480 buyers, because it's for very thin budget PCs. And you can push 750Ti a lot actually. But who cares when NVidia does it?
Look at this video (TBH first I checked)

+200MHz on core = over 15%
+400MHz on memory = over 15%
That's a lot and you need power to feed this OC. It's made on cheap AsRock H81M-DGS mini-ATX mobo for around 50$ new.

I'm not defending AMD for this mistake, that shouldn't have happened, it's bad because AFTER OC some of cheapest MB can not handle it (still no chance to fry MB...) and will reboot or go to BSOD in worst scenario.

 

Just saw this. Hope now everyone will understand what @Drivver and me mean.

 

This is fixed in a driver update. Many cards have done this, and tests have also been done to test and see just how robust the PCI-E slot is.
You could send over 300 watt through that PCI-Express X16 slot and it still wouldn't break. You'd be much more likely to starve that circut of the power supply, then to ever blow the slot up.
Over 20 years of experience in PC hardware will tell you this isn't something to worry about.

Also, the 750Ti does exactly that, and there haven't been any slots blown by that card.

 

actually, it doesnt, the Ti remains within the 75W limit of the slot, hence why the Ti's (and not standard 750) has a 6 pin, to allow to to get more than 75W

 

Reference 750Ti don't have additional 6pin connector, non OCed draw a lot of time over 100Watts with jumps up to 140Watts. Still you can OC it a bit and numbers will increase a lot, similar with some AIB cards that have 6pin, but card will work without it and are capable of small OC. Look at Tom's Hardware. Anyway RX 480 couldn't damage any mobo here, it would rather jump to bsod at most.

Tell me more about it.

 

It'll be interesting to see how the 490 performs, sure it will hold a significantly higher price tag - if you are budget building - but if they follow through the budget price spec it might be a bargain 'high end' graphics card. I have no idea when they will release it, but i assume it must be within the next couple of months (in the past the 280 - 290, 380 - 390 have released side by side from what i can see). If it performs well, I will probably purchase a couple and crossfire them. As for the 480 power 'issues' you shouldn't let that put you off - as discussed there is pretty much 0% chance of bad stuff happening to your mobo (not to mention the fact that as soon as you start overclocking a video card, you start increasing power draw from the PCie lane(s), this hasn't been a problem in the past).

 

Yeah they fixed the issue in drivers like 2 weeks ago anyway, now it draws only 75w from the PCI lane and has no dips in performance from what has been said so far.
