XFX RX580 -- No Display
I have a XFX RX580 which does not have any display. I checked all voltages are OK, 12V, 3.3V, Core Voltage, VRAM voltage all OK. The clock is generating signal(good sine wave on pin 6). Now the BIOS chip depending on the one i switch to, on pin1 is stuck on High and the oscilloscope shows a continuous square wave and does not stop even after 15 or 20 sec when i turn on the machine. It does the same on the second BIOS chip as well. I am not able to figure out what to make of this. As far as I know the chip select signal on pin 1 stays on for only 2 sec and goes off and while its on it generates...

Re: GTX 1060, Recognized but no display, error 43
Its not possible that all bits are faulty. what i would suggest is with GPUZ to check what is the VRAM modules brand showing and then physically opening the graphic card and checking the VRAM brand on the modules. I suspect the VRAM modules may have been changed. Its just a guess though. but i would check this first as it gets detected.Last edited by SMDFlea; 09-26-2023, 02:51 PM.

Re: Software to analyze Video RAM faults on graphics cards?
you don't need to convert the file extension. download diskgenius from the diskgenius website. just enter the keyword "diskgenius" in google and the first result is the correct one. .pmf is a partition format and readable with diskgenius. Download and install the application. with diskgenius you need to restore the partition file which are the .pmf files. Along with the folders you have downloaded from Bozog's torrent link, there is a video and a pdf file which demonstrates how to go about creating...Last edited by frazerxavier; 02-01-2022, 05:09 AM.

Re: XFX RX 5700XT No Display
here is a board view for MSI RX 5700XT. the layout is not the same but the connections are similar. If anyone else has a schematic for XFX 5700XT please post....

Re: XFX RX 5700XT No Display
For now i have attached a typical schematic which connects a crystal Oscillator to GPU and GPU to BIOS Chip. This is a typical circuit diagram which is commonly used on graphic cards. I will post a 5700XT schematic diagram of another GPU when i get home in the evening. Most part in the schematic is same or similar and can help in diagnosing this issue....Last edited by frazerxavier; 01-29-2022, 02:54 AM.

Re: XFX RX 5700XT No Display
I think the rest pin is the one of the last 3 pins on the right side of the PCIE lane at the back of the card towards the cut side where the 12V and 3.3 volt set is. I have attached a pic for your reference circuled in red. I'm not sure which one but it can be checked using a schematics any 5700xt schismatics would do as this part would be the same for all. i may have one 5700xt not xfx but some other. i will post here when i get home in the evening....Last edited by frazerxavier; 01-29-2022, 03:00 AM.

Re: XFX RX 5700XT No Display
This part is the same as what i recommended to check the 16 pairs on the PCIE lanes which you have marked with a green circle. Front side and back side....

Re: XFX RX 5700XT No Display
That resistance looks bit too high. might have to trace using a schematics for a 5700xt....

Re: XFX RX 5700XT No Display
Ok now check with multimeter on resistance mode if the side which gave the wave signal and pin 6 of the bios chip have a direct contact. should look like a short. I would say test Pin 6 again too if required.
Now this is what i'm assuming as this has reached outside my league. i would wait for someone with more knowledge to assist here....

Re: XFX RX 5700XT No Display
I have marked it in blue. one or 2 sides of the corners should generate frequency. If some expert would comment on how to exactly test a crystal Oscillator would be great....Last edited by frazerxavier; 01-28-2022, 11:52 AM.

Re: XFX RX 5700XT No Display
Don't give up yet. i am out of options here but wait for some expert to comment. You wont regret. the CH341 programmer does not require the chip to be removed. it comes with clip which can be placed directly on top of the chip to read and program it. but if there is no clock on pin 6 then check the clock on the card with an oscilloscope. i have attached the pic of a clock for a GPU. its similar on 5700XT....Last edited by frazerxavier; 01-28-2022, 11:18 AM.

Re: XFX RX 5700XT No Display
I don't recollect the orientation and the image is not clear but pin 1 is the side which has the dot. Don't forget it's a dual bios. there are 2 BIOS chips. one in the front and one at the back. And there is a selectable switch.
I have added and example from a RX 580 which uses a chip from the same manufacturer....Last edited by frazerxavier; 01-28-2022, 11:00 AM.

Re: XFX RX 5700XT No Display
on the bios chip check pin 8 if there is 3.2V. if yes put your oscilloscope on pin 1 when powering pc on if there is noise (weird fuzzy waves) while staring up. if yes check pin 2 and pin 5. there should be some noise on those pins as well when starting up. pin 2 and 5 are used by the GPU chip to send and receive data from and to the BIOS chip. Also check if the clock is working on pin 6 with the oscilloscope. If there is VCC on pin 8 and noise on pin 1 but nothing on pin 2 and 5 or noise on pin 5 but nothing on pin2 then if you have a...Last edited by frazerxavier; 01-28-2022, 10:48 AM.
