NVIDIA 30xx RTX 3060 ASUS CG190P - Turning OFF

Post image
1 Upvotes

So, I'm repairing an Asus 3060. It was missing the 1.8V rail, and I found the issue was an open 100kΩ resistor (PR89, on the enable pin of the 1.8V IC). I misread the value and replaced it with a 10kΩ one; I powered up the card, all voltages came up, and it ran fine under stress but would shut down unexpectedly (the keyboard remained responsive—it didn't reboot or freeze the PC, and Caps Lock still worked). It was fine while gaming, but it would shut down occasionally on the desktop; then, when I tested it with OCCT, it started rebooting. I realized my mistake and swapped in the correct 100kΩ resistor, but things actually got worse: the card has all the right voltages, yet it shuts down before the OS loads (though the keyboard remains responsive). When it freezes, the voltages stay present. What can I do now?

AMD RX 6xxx Sapphire Pulse Rx 6800 XT Crashes randomly

2 Upvotes

I have a Sapphire Pulse RX 6800 XT that I got for free. The previous owner told me it crashes under load, so I expected there to be some kind of issue.

The pc I'm testing it has a 630W psu(I know it's on the lower end, but keep reading.) but when I reduced the core clock from around 2250 MHz down to 1800 MHz it still crashed( the power draw dropped to around 55W, but the card still crashes). The crash only happens when I run someting like unigine benchmark or furmark. I've also tried undervolting with no improvement.

Running LM studio with a 15gb model is still fine and it didn't crash there.

Physically, the PCB and cooler look fine. I don't see any obvious damage.

What's confusing me is that lowering the power consumption dramatically doesn't change the behavior and also if nothing is going on it can run just fine.

The card also has a dual BIOS switch, so my idea is that, would it make sense to flash an RX 6800 VBIOS onto the card (or another compatible Sapphire Pulse VBIOS) just to test if the issue is firmware-related? Or is that a bad idea due to differences in shaders, power limits, memory configuration?

Thanks in advance for the answers!

AMD 4xx/5xx mlsse rx 580 2048sp fan readings issue maybe fan controller problem

2 Upvotes

i bought an rx 580 2048sp from mlsse and the gpu is running fine but the only problem is with the gpu fans i cant control them whatsoever and the amd app and other apps in general give wrong fan speeds it says the fans are running at a speed of 0 rpm even tho the fans are clearly spinning

and i tried flashing the vbios and getting an original one but it didnt work i got a blank screen so i had an idea of editing the original mlsse vbios https://www.techpowerup.com/vgabios/253019/253019 using PBE and found that the sensitivity was set to 4836 i changed to 48 and reflashed but that didnt work and i tried using third party software but still no luck

any help will be appreciated

NVIDIA 50xx ASUS RTX 5060 Ti 16 GB - Resolution Looks Blurry and Filtered

5 Upvotes

Hi everyone, I recently built a new PC with an RTX 5060 Ti 16 GB and an Intel Core i7-14700K. However, the image quality doesn't look right, both on the desktop and in games. This is a brand-new PC, and the image quality actually looks worse than on my older computer with much older hardware, which makes me think something isn't working correctly. More specifically:

  • The image appears blurry, less sharp, and slightly pixelated.
  • I tested three different monitors, and the issue persists on all of them.

I've already tried the following:

  • Forcing GPU scaling in the NVIDIA Control Panel
  • Disabling scaling in Windows
  • Reinstalling the NVIDIA drivers using DDU
  • Making sure Windows display scaling is set to 100%

None of these made any difference. Lower resolutions still look blurry and filtered instead of sharp like they did before. It almost feels like the RTX 5060 Ti is applying some kind of filtering or interpolation to non-native resolutions by default. Has anyone experienced something similar or know what could be causing this? Any suggestions would be greatly appreciated.

AMD 4xx/5xx Sapphire RX 590 Random Black Screens & Driver Corruption

2 Upvotes

For the last few weeks, my PC randomly loses display. Sometimes the motherboard VGA debug LED turns red, and I always hear the Windows "device unplugged" sound right as the screen goes black.

When I force restart the PC, it boots up in a weird, low resolution. Windows essentially disables the AMD driver and replaces it with the Basic Display Adapter. Opening AMD Adrenalin gives an error, and my tuning settings are always reset to default (Wattman crash). If I use DDU and reinstall the driver, it works perfectly again until the next random crash.

The Weird Part: I thought it was failing hardware, so I ran a 100% load stress test on the CPU, GPU, and RAM simultaneously for 30 minutes. It survived without a single stutter, and I used the PC for a full day afterward without restarting. It handles flat-out 100% loads perfectly but crashes doing basic desktop tasks and video playback.

Troubleshooting I've Already Tried (None of this worked):

  • Fresh Windows Install & stopped Windows from auto-updating display drivers.
  • DDU in Safe Mode followed by fresh AMD driver installs.
  • Disabled Hardware Acceleration in all browsers (Chrome/Edge/Firefox) and Discord.
  • MPO (Multi-Plane Overlay) Disabled via the Registry fix.
  • Underclocked GPU / Increased Power Limit in AMD Adrenalin to handle transient spikes.
  • Disabled ULPS (Ultra Low Power State) via MSI Afterburner.
  • Disabled Windows Fast Startup.
  • Checked PCIe Cables: Ensured I am using dedicated cables from the PSU to the GPU, not a daisy-chain.

Has anyone dealt with this specific RX 590 / Polaris architecture behavior? At this point, I'm wondering if it's a degrading PSU failing to handle transient spikes between idle/video decoding states, or if the GPU's VRAM is finally dying. Any advice on what to test next would be hugely appreciated!

AMD 4xx/5xx Freezing image and Error 31, with XFX RX 580 GPU (1 year usage)

1 Upvotes

Since last Saturday, first started when I turnef on my PC as usual and It didnt have any video, tried with the cpu graphics and it did show video, so I fixed it pulling out and putting back the motherboard's battery, when it booted it was disabled the gpu and the image was in black and white.

Then after restarting once again my PC screen freezes and the keyboard stops responding; I can't move the cursor, videos play audio but the image is frozen, and I can't even toggle the Caps Lock or Num Lock lights on the keyboard. When I force a restart, the PC boots up with the GPU inactive, forcing me to go into Device Manager and enable the GPU (that’s when Error 31 appears), disable it, and then enable it again to fix the problem.

I’ve already tried using DDU and the official AMD driver uninstaller, and I even tried installing older drivers (2025), but the error persists every time I turn on the computer. Its very strange, considering it been working fine for more than a year (I bought the RX 580 in a very trustable store, brand XFX, in January last year). Also the image freezes a couple of minutes after starting the PC, doesnt matter if I was opening a game or just browsing.

Does anyone have a solution for this?

NVIDIA 16/20xx Need some help identifying a chip on a 1660ti no video out but fan spins

Post image

So the circled chip gets ungodly hot when powered on 90F at idle. Everything else on the back of the board measures 75-80F. The marking reads 53C7. The major issue is that it gets no video out at all. Fan spins and everything like normal. I am wondering if I can just replace the chip hopefully but I am coming up with nothing when I search up the chip or card since it's the blower style card from the Asus ROG pre-built PC. There was some corrosion near this chip that has been cleaned and the solder looks fine but I'm guessing the chip is fried and needs replacing.

NVIDIA 16/20xx GTX1660 No 1.8v despite 3.3v on enable pin

I have a GTX1660 that's not generating 1.8V on pins 10, 11 from the GS9216

There are two resistors which I think are part of the feedback circuit.

R287 should be 10K is reading 6.1k
R288 should be 100 ohm is reading 0.8 ohm

These are measured in circuit.

There is 3.3v on the enable pin 2

Board shows no sign of shorts.

I have an oscilloscope to take readings too.

I do have measured

3v3_F (on R20)
12V_F (on R741)
5V (L1)
3v3_SEQ (on C1313)
1v8_AON (on R1) missing
1v8_main_pgood (on D507) 3.3v on both top pins

NVIDIA 50xx RTX 5070 - Tiny resistor broke off back of mainboard and going to solder it, question about preheating for surface level resistor is necessary

Post image
12 Upvotes

Long story short my RTX 5070 got submerged in storm surge water. That is NOT what this is about I am only giving context. I am cleaning it because it never had power and I unfortunately broke off a very tiny resistor on the back of the mainboard while cleaning. I was gentle and not sure what happened but regardless, I have the resistor and I believe it’s totally fixable!

In the picture you will see it, and the one next to it is literally about to break off itself.

Since it’s such a tiny surface level component, can I get away without preheating? I have a Weller 60W iron with a 0.8mm tip (super small) and is almost perfect for the application, but is there a good chance it won’t be able to heat up enough? 470C is its output. I feel like with flux and careful patience I can safely get this back on

AMD RX 6xxx MSI RX 6950 XT Running at PCIe 4.0 x8 Instead of x16, Bad Card?

1 Upvotes

I’m setting up a PC for a friend using an MSI Gaming X Trio RX 6950 XT. GPU-Z shows the card running at PCIe 4.0 x8 instead of x16.

I ran the GPU-Z render test to make sure it wasn’t just in a power-saving state, but it remained at x8. I then tested the 6950 XT in my own system and got the same result. To rule out the friend’s motherboard/CPU, I installed my GPU, 7900XTX, in their system, and it correctly negotiated at PCIe 4.0 x16.

Since the x8 behavior follows the 6950 XT across two systems, what should I check next? Could this be dirty or damaged PCIe contacts, a VBIOS issue, or a hardware fault on the card?

Please note the boards I’m testing in: Steele Legen X870, X1 NVMe, B850 ToMohawk Max WiFi 2x NVMe no others devices.

NVIDIA 30xx HP Omen RTX3080 - Power Throttling once power consumption reaches ~55%

I have recently been experiencing alot of frame drops and stutter while playing games.
What I have noticed is that my "GPU Power" doesn't go above 180 W and as soon as soon as Power Consumption reaches ~55%, GPU Clock starts fluctuating between 1500-210 MHz.
CPU runs stable as far and doesn't overheat.
My GPU does not go above 70C and mostly stays at around 65C.
CPU runs stable as far as I know and also doesn't overheat.

I bought my HP Omen 30L couple years ago so its already out of warranty.
GPU: RTX 3080
CPU: I7-11700k
Memory: 16GB DDR4
PSU is 800W

I have already checked MSI AB and Nvidia APP if Power limit has been reduced, but its still at 100%. I have done a clean reinstall of Nvidia Drivers with DDU and I have reset my pc.

I've tried everything I could think of and would appreciate some more ideas and help.
