There is a 9V optocoupler on the 4th leg. The optocoupler is new and working, tested by a probe. There is no other arduino. Which one is better to buy on ATmega328P or Atmega168P?

Ok, test the Arduino then. Try different HV_EN and HV_FB pins, if default ones aren't working. ATmega328P has more flash memory and EEPROM storage, so it would be a better choice, IMO.

I tried to repeat HV_EN on D10, the same thing. Thanks for the help. I'll buy a new one, then I'll write.

Hello! I can't do it. I bought another Arduino nano, everything is the same. I checked the scheme more than once. The DIMM adapter is working, another programmer is reading it. All the elements are according to your scheme. What's next? I'm using version 20231210, and it's the same with 20230930.

You can measure the voltage on the D9 HV_EN at the time of Arduino initialization in the RW_SPD program. I have less than 1 V. on D9 , and in order to open the optocoupler, you need > 3 V. How do you power the Arduino, via USB or an external source on the VIN?

How do you run the RW_SPD program then?

It seems like your VOUT- is connected to SDA or SCL line. If that is the case, your SDA or SCL pin is grounded via VIN- pin, which could be the reason Arduino can't see any I2C devices. Check the resistance between SDA/SLC and GND. It should not be 0.

I used exact same DDR5 adapter. Everything looks good with your work, you used correct pins, and wiring and soldering looks good.

Hi a213m I have an asus b760-I board can't clear write protection. Is there a way to do it? I can do testing on it if needed. I have couple ddr5 sticks with CRC errors and want to restore them. I can boot it even with bad crc to windows and reed spd but can't write to them.

Hi, Clearing DDR5 RSWP via Smbus with SPD-RW is only possible with Asus's Maximus boards that have MR_TEST2 jumper. Your best way is to either build an Arduino programmer and use that or physically short HSA pin on your DIMM to ground, boot with one DIMM and use Clear RSWP command. You can short HSA to ground right on the DIMM itself, motherboard's DIMM slot, or better - get a DDR5 slot adapter, and short its HSA contact to GND and install your DIMM via such adapter, then use Clear RSWP command as usual. By default Smbus RSWP command are disabled, to enable check this post.

I order all parts to build arduino programmer for this but it will take some time to arrive. Shorting the pin is possible by a thin wire on a mobo dimm slot. But I cant boot on one corrupted stick I can only boot on both sticks. Also both need to be disabled. Can I for example short HSA on both ram slots boot and clear RSWP after? PS I found those contacts on my motherboard looking at bordview but they are not pins but just solder testpoints but can be shorted to ground anuway.

When HSA is shorted to GND, it forces SPD hub to run in offline mode with a fixed address of 80. Per Jedec's specifications, you cannot run more than one DIMM in offline mode, as it would cause addressing conflicts. If you can't boot with one DIMM, you can force offline mode on just one DIMM, as long as the other DIMM does not reside at address 80. Then clear RSWP on DIMM at address 80, flash the correct SPD and swap the sticks around to fix the other DIMM.

DONE RSWP was removed on asus strix b760-I ! Shorted address 80 slot's SHA to ground by inserting very thin copper wire in side the corresponding hole in the slot. Than Installed corrupded stick in 80's slot. Installed a good stick in to slot with address 82 and booted up to windows. Program hanged up on first attempt but on second attmpt i got message that RSWP was removed on b760. After I flashed the spd from working stick to not working and it's now looks like it's working!
