Hi mates,
Does any one tell me which one is the faulty ram? Or is it more than that?
If you open the Cpc, you'll have a look at the chips.
In case the brand of your RAMs is µT, replace em all.

And isn't this a typical conflict with amsdos?
Check if pin22 40015 is low. When the test is performed.

See Amstrad Diagnostics Wiki (https://github.com/llopis/amstrad-diagnostics/wiki)
IC212 74LS74 pin5 is Hi. AMSDOS is ON.

The Number 07 at the bottom of the Photo indicates it is "BIT 7"
Keep Safe

I couldnt find IC212 or 74LS74. And if i find them, i have no idea what am i gonna do with them.
Edit: Btw i tried to piggyback on every single upper side, there is no change on test. The result is the same.
And Could You find 40226?
I find IC212 on your photo in other topic 8)
Finally change the IC126 and it works ;)
Only one RAM from second bank? :o :-*

Can happen but best to run a soak test, as I have had a second IC fail sometime later.

why not?
the warmest place ... nearest keyboard and 2 capacitors on left and right.

Could of course just be a random failure. They don't need much convincing to fail! :D

Yeap, just one ram. Before changing i try the piggyback method, check the heat of rams etc but non of them works.
As a final resort i change the IC126.
And i also run the soak test as well.
There's no problem.
