guys i want to flash bios for fake 1050 ti but when i press detect nothing happens
 
Check connections carefully and that you have right version of software.
there should be a tutorial out there.
 
on the version 1.18 nothing says and on 1.34 say detection failed could not find the chip (but im sure its properly connected)
and on 1.30 says acces violation 0097EA47, Write of address 00ECC15A.

how do i know if i have the right version
 
Did you follow the guide?
 
Can you make a picture how it is connected on the card and the CH341 programmer?
Also a clear picture which chip you are trying to flash

I assume you mean Pm25Lq020, which should be the correct chip. I am not sure how this chip is placed on the PCB, but can you confirm the red wire on the clip is placed on pin 1?

99% cases those are bad clips. I almost never use those.

Auto detect does not work for some ICs also

yes ots pm25lq now i saw the q on it but on ch341a programmer is no chip with Pm25LQ020

when i press detect nothing happens i tryed with Pm25LV020 say detection failed idk why its connected good

Do you see the pins within the SOIC8 clip making proper connection with the chip?
 
it crashes because it doesn't bring back the correct amount of memory.
 
It looks like there are only 3 pins on one side of the SOIC8 clip. Can you confirm the SOIC8 clip has 8 pins in total (4 on every side?)

Try to wiggle the clip a couple of times, maybe it is just making bad connection.
 
friend, some pliers are really crap, cheap solution is to solder wires directly onto the chip if you can't check if the contact is good.
or buy a decent pliers. furthermore, as I wrote to you previously, the software is also important because there are many versions around.
some work well and support several spi flash, others do not work.

I’m guessing you didn’t read the guide either

my ch341a works fine and I didn't need to read it. but I had suggested at the first reply that op find it and go read it .
It happened to me on a few occasions that there was no space to attach the pliers and I soldered on the chip and did the job without problems.

with the ch341a I made my first biosmod desktop pascal gpu, let's see if you can do it.

Yes the clips are what I think the issue is too; just for everyone’s sake though the guide literally covers the 3 most popular software used with this type of programmer. As well as what to do if the exact chip is not found in the DB

I do not think so...
and I haven't read your guide.

Good now that that’s established the OP can ignore your advice. You don’t appear to know what you are suggesting given what OP already knows. @VuurVOS seems to have a great handle on it. The issue imo for everyone else is going to come down to the software used or the chip selected. Though I would make sure the connector is in the proper orientation on the programmer or his clip would literally be backwards. It’s also worth noting he should check his voltage switch.

I think we are communicating but we are not explaining ourselves well, probably differences in language and translator.

I didn't have any problems rotating the connector clamp because the software shows it on the screen, I took it for granted.

I exaggerated with old age... :D s3 virge
