AMD RX 480 problems

[Feoilban]

I didn't say dangerous nor did I imply it. I said defensive and mean-spirited. Perhaps reading and comprehension aren't your strongest suits.

Haha .. Look at your post above and the whining about AMD hardliners .... Get a grip man

This is some way to treat someone just asking for help.

Where did he ask for help?

I've found AMD hardliners to be quite defensive and rather mean-spirited. I'd hate to ask for help if I ever bought an AMD product.

Point out who was mean spirited? This "amd hardliner" statement has been the most offensive post in this thread.

I'm pretty sure the card never harmed your motherboard if you where not able to get it to work. It only draws that power a load I'd imagine.

Was the UEFI only theory tested?

I doubt the card killed the mobo - there's no reason why it would be drawing >75W through the PCI-Express slot just to boot.

Under the spec, no card should exceed 75w through the pcie slot during post. It more than likely is a compatibility issue due to the card being UEFI only.

The motherboard will display the same error code with or without any GPU
CPU is heating up so that part works
That Dell T3500 will be hitting the bin after i am satisfied with the RX480
The RX 480 is still working in the Dell t20 overclocked just ok

The weird problem is that windows was reporting ERROR 43
And the card was not running properly
The death was after swaping the Pci Express slot to attempt to get it working
Power draw at bootup was 170-190W
Within reason

The card will be getting a new home with new components
the Xeon X5672 was sufficient for the job so the system was still used, or was in use

Back to the story the error code 43 is a concern as it might be as other people have noted that the card might not be compatible with some older hardware

According the BuildZoid who live streamed himself OCing/Watercooling and adding more caps (and attempting hardware volt mods), the GPU takes its power solely from the 6-ping connector, and the PCIe connector feeds the VRAM and possibly other stuff on the PCB.

Wrong. Half the vcore power phases (the VRM is 6 phases) are fed from from the PCIe connector, the other half from the 6-pin.

Watch his 'Overclocking Livestream 13: RX 480 first session part 2' at 58min.

3 x FX480s @stock running Firestrike Ultra and my motherboard survived too.

Ah, I turned it off before that point in the video. It completely goes against everything he said at the start.

I did contact Asus about the PCI power draw and got this response:

Dear Mr. Greg,

Thank you for contacting Asus, my name is Allen and I will try my best to assist you with your situation.

Please feel free to rate our service according to the solution provided in the questionnaire that will be sent to you shortly after our reply to your inquiry.

I inform you that usualy the motherboard will not allow the graphics card to draw more than 75W even if the graphics card doesn't have a set limit to this wattage.

Unfortunately we are not able to test if a graphics card that doesn't use the correct limits for the PCIe port can or will damage the motherboard.

We understand that AMD will release a patch for RX 480 in a few days and we advise that you contact the vendor of your graphics card to make sure you have the latest revision installed.

Should you have any further questions, please do not hesitate to get back in touch with us.

Best Regards,

Allen

Who cares? Nvidia cards draw more than 75w. Non story, Non news. blah blah blah

Oh, you mean 960 Strix? http://www.pcper.com/reviews/Graphi...s-Radeon-RX-480/Evaluating-ASUS-GTX-960-Strix

Spoiler

One interesting note on our data compared to what Tom’s Hardware presents – we are using a second order low pass filter to smooth out the data to make it more readable and more indicative of how power draw is handled by the components on the PCB. Tom’s story reported “maximum” power draw at 300 watts for the RX 480 and while that is technically accurate, those figures represent instantaneous power draw. That is interesting data in some circumstances, and may actually indicate other potential issues with excessively noisy power circuitry, but to us, it makes more sense to sample data at a high rate (10 kHz) but to filter it and present it more readable way that better meshes with the continuous power delivery capabilities of the system.

Some gamers have expressed concern over that “maximum” power draw of 300 watts on the RX 480 that Tom’s Hardware reported. While that power measurement is technically accurate, it doesn’t represent the continuous power draw of the hardware. Instead, that measure is a result of a high frequency data acquisition system that may take a reading at the exact moment that a power phase on the card switches. Any DC switching power supply that is riding close to a certain power level is going to exceed that on the leading edges of phase switches for some minute amount of time. This is another reason why our low pass filter on power data can help represent real-world power consumption accurately. That doesn’t mean the spikes they measure are not a potential cause for concern, that’s just not what we are focused on with our testing.

Sorry for bumping a 11 month old thread but as the solution to the OP's problem was never found I figured I should provide it for anyone landing here via search as I had the same issue this week with a T5400 and an RX480.

The Code 43 error with the RX480 basically means the non UEFI board had trouble initializing the card on boot, it's quite a big problem as it will essentially make the card unusable but there is a simple solution (well, simple depending on the parts at hand). Simply remove the card from the system and boot from the onboard graphics if present then go into the BIOS and set the onboard as the first initialize graphics option, then power down, reinstall the RX480, connect the monitor to it and reboot. This should fix the Code 43 issue (as a side effect you may not get a display until windows loads, so if BIOS access is needed you would have to swap the monitor cable to the onboard).

If you don't have onboard graphics then you need to do the same but also install either another PCI-E card in the primary slot or a PCI card (if possible), yes this does mean you have to leave a redundant graphics card in your system just to make the RX480 work (in my case a Quadro NVS lol), but it's better than nothing.
