Re: Request for help to identify a component on an R9 Fury X please.

That to me is not a very good Warranty. The Manufacturer should be the one to RMA the card and not the place of Purchase. Suppose the Place of purchase closes or goes out of business. Also having a One year Warranty on AMD Vega cards and any Reference AMD Card that are so expensive is really a joke.

The Warranty also doesn't mention if the card that failed and is RMA through the place of Purchase whether they will replace it if it can't be repaired.

I know that Asus, as far as I know, doesn't care who owns the card as long as you provide a good serial number. Visiontek has a limited Lifetime Warranty. that was over five years ago when I Purchased a HD 7850 from them. Dell, according to their website, sells and uses Visiontek GPU cards.

It could be why their GPU cards are less expensive than normal because the Company doesn't have good support for the product.

LoL, you sound like a Electric/Electronic Engineer. My training is from the Military in the 70's and 2.5 year of Electric/Electronic Tech school in the early 80's and over thirty years of troubleshooting Electro/Mechanical computerized equipment.

I understood basically what you are saying (not all ). If the B200 was a fuse, I would think the Reference name would include a "F" like BF200.  By the picture it has two contacts. It could be some sort of sensor like you mentioned. The card uses Three fans right? That is a lot of current to run three large fans.

The User of the other R9 Fury had the same problem. The computer shut down and when it restarted the card was bad. I am beginning to wonder if something in Windows 10 is causing , at least , Sapphires GPU cards to "blow up".

Hi,

The Sapphire Warranties here are similar story. I contacted Sapphire Support about it. The warranty only stays with the original owner provided they have a receipt, not that the PowerColor Card has anything to do with Sapphire. There are a number of Sapphire R9 Fury X that are available and also a Radeon Pro Duo that I was thinking of purchasing. However, I think it it is a high  risk today to buy any high end second hand GPU.  I think R9 FuryX Liquid Cooled Cards are pretty good for Etherium Mining. If you look at the Specification for those FuryX Fans they have a very long MTBF. Any indication of any problems with the fan on any 1-2 year old GPU indicates heavy 24/7 use or mining to me following this experience.

Hi,

My PC did not fail to boot. The PC booted fine, which indicates no electrical shorting to me.
The PSU has overcurrent protection trip, if anthing had shorted the PSU supply then the red trip light would have come on and I would have had to reset it before next attempt to boot up.

The card simply died, no fan, no GPU tachs, no display output. The Red Radeon Logo came on.Thats it.

The R9 FuryX has a single fan. I do not think it runs at 3000 r.p.m. though.
The actual operating current on the R9 FuryX would possibly be lower, it depends on the PWM controller duty cycle that is used to control the fan speed.

Thanks again for all of your help.

I will power down this PC, remove the primary PowerColor R9 Nano and see if I can work out if there is a B200 on the PCB and see if I can work out what it is.

Bye.

Hi,

There is a B200 on the R9 Nanos but it is underneath the cooling shrouds and not accessible.
I would have to remove the cooler and I do not want to remove them at the moment.
Also the Fan on the R9 Nano is completely different to the Fan on the R9 Fury X so there is no guarantee that the component value would be the same.

Some good news - I just received a full refund for the cost of the card so I can now decide if I want to risk purchasing another second hand R9 Fury X
or if I should just keep all of the new and second hand R9 Nano's I own and move on to purchase a new GPU.

Prices of new cards have now dropped again here.

I have seen new two slot high PowerColor RX Vega 56 Red Dragon announced however no 2 slot high Vega 64 Red Dragon and Performance/Price is still an issue.

I see rumor that AMD is working on new GPU for release this year but I cannot really wait for new GPU any longer: 
AMD RX 600 Series GPU Project "Zen" Detailed - Radeon on Steroids to Amp Clock Speeds & Efficiency
I will wait to see what Nvidia announce for next gen GPU's since they seem to be moving forward with support for OpenCL 2.0 recently, which is the main reason why I stayed on AMD cards last year. I need to do more investigation on that, and I also need to check if Windows 8.1 64bit support will still be there on new Nvidia cards.

I have been told I can keep this broken R9 Fury X card but I do not think it is repairable and I have insufficient information to attempt to repair it. I do not want to risk fitting it to my PC's.

If anyone with an R9 Fury X has removed the card from their PC and could take the time to open the backplate on their card by removing four screws, and measure B200 and tell me what that component is I would still be grateful to know.

Also if anyone has any more details about the Fan Controller on the R9 Fury X, or any success with changing the R9 Fury X fan to a different model I would be grateful to get information on that.

I think I have done all of the investigation I can on this for now.

Thanks again for your help.

Bye.

Hi,

Here is a breakdown of the PowerColor Vega 56 Red Dragon PCB for anyone who may be interested.

Hi,

I just purchased and completely QA tested a second hand Sapphire R9 Fury X. The card was tested on ~ 80 of the latest AAA games and benchmarks on Windows 10 64bit with Adrenalin 18.3.4 driver. The results are pretty impressive, especially when paired with my best PowerColor R9 Nano.  

Since I keep the card I removed the backplate by pressing down the Sapphire Sticker which covers the backplate screws over the screw locations, using a tiny craft knife to carefully cut circular hole 'flaps' on the Sapphire Backplate cover, removing the screws and taking the backplate off.

I used a standard multimeter on 200 ohm setting to measure across the B200 component, I also tried the Diode meter across the component.

Here are the results.

B200 is not a diode.

B200 is not a capacitor as it does not register as an open circuit.
B200 measures at 0.3 -0.4 on my multimeter.
Shorting  the multimeter leads I see 0.2 - 0.3 depending on how hard I push the leads together.

It looks like B200 is a fuse on the good Sapphire R9 Fury X card.


This is good news and bad news in terms of looking to repair the failed PowerColor R9 Fury X.
Fuses can be replaced in a normal circuit and the circuit should still work.
This makes it pretty difficult to figure out what value the fuse value should be though ...
I guess I will try to calculate that myself, assuming the fuse is in line with the power supply to the fan.

Wish me luck.

After some effort I managed to repair the Blown R9 Fury X Fan Controller.

The GPU is now running fine.
I disassembled the R9 Fury X completely and cleaned the PCB with Isoproyl Alcohol.

I did not touch or replace the thermal paste on the cooler.
I replaced the blown component with a '0' Ohm surface mount resistor rated to blow if the fan windings short out.
I soldered the connection as follows using a battery powered soldeing iron with a very thin tip and some thin strands of AWG wire.
I used a magnifying glass from a "hobby hands" set to solder the smt resistor to the wire strands  and then connect the wires onto the Lowest  Pad and the red fan lead pin:

Solder Connection:
Lowest "B200" pad ---> '0' ohm surface mount resistor--> Blown "B200" Pad (Red Fan lead pin (Fan "VDD"))

The replacemt surface mount resistor runs horizontally from the lower "B200" pad across to the Red Fan Lead pin on the fan header.
It was to difficult to get a connection to the top Blown "B200" Pad.

I just did the soldering to the surface mount resistor by hand because I was just doing an initial test to see if repair was at all possible.

I will replace with a proper through hole to surface mount pcb to through hole adapter if this GPU lasts for more than a month after repair.

Here is a picture of the Blown Fury X in operation- it is running outside my PC case via PCIe2.0 mining adapter.

I connected a Corsair HD 120  RGB  "Pull Fan" driven from my PC Motherboard and controlled by AIsuite3 and Corsair iCUE to the other side of the radiator.

The fan speed control is working on the supplied fan that came with the R9 Fury X. It only runs at 1200 r.p.m and is only rated at 0.1 Amp  but I will look for a replacement Fury X Gentle Typhoon 3000 rpm fan in the future which has a rated current of 0.22 amps.  The rated current of the HD 120 RGB fan is 0.3A, so I will not drive it from the R9 Fury X just in case i blow the fan controller "fuse".

Here is the Repaired R9 Fury X running Compubench Ocean Surface Simulation.

In conclusion GPU "repaired". It will be interesting to see how long it lasts though.
I still need to replace the thermal paste, and run more extensive test on the GPU so I will leave it for now.

Thanks for everyone who helped with suggestions on how to fix it.

Bye.
