Multiple bad RAM areas, is it possible to disable each of them?

[HubbyGitGuy]

Hi there, I have multiple areas of bad ram and wondering if all of them can be disabled? I have attached screenshots of each area could you help me to complete the file to put into rEFInd? Thank you so much.

I went through a long process testing small areas of the RAM to find each section. Strangely I also found one section that did not appear to test like the other areas, it seemed to just extremely quickly go through some text over and over and over and gave no errors. The text was too fast to read but seemed to be going through each of the memory test titles at lightning speed, if I was to guess.

Thank you so much for your help with this I am extremely grateful.

Ok, so if you have multiple defective areas, the Error Reporting Mode "Error Summary" is not the best choice. Better switch to the "Linux memmap" reporting Mode to see all the errors on the screen.

Also make sure that these errors are at the same place if you run memtest again - it is possible that you have an hardware fault, that doesn't let you identify static places of the errors - then you are out of luck and have to consider hardware repair.

But in case the errors stay at the same place, you can simply run the disableram utility multiple times before booting - every time with a different error-range.

Best to use an .nsh script for this - read and follow the Readme of this page. Post your output of memtest ("Linux memmap" error reporting mode) here and show me the nsh file you came up with.

Sorry yes, what I meant was the "BadRam Patterns" Reporting mode. Please post the result here; I think it will be necessary to transform the Patterns into regions - I can help you with that.

Maybe it is related to a warm device? Could be that the ramchip has a small connectivity issue and the issue may only arise when the macbook has a certain temperature?

Also make sure your battery is good, because the battery could be bloating and pressure the ram chipset.

I don't know which test selection would serve you the best.

here is a picture of multiple bad areas using BADRAM patterns.

1. Could you please explain on how to turn these patterns into regions to put into OC. Can I use your new script for it and how?

2. Is there a way to make memtest86+ window bigger resolution on Mb 16” ? It looks tiny cause it always open 640x480 :(

Ok, this seems a lot of defective areas. Do they stay the same if you run this again? I will look into this as soon as I can afford some time.

Thank you for your reply.
Yes, I have run memtest few times and it stays the same after many hours of testing.

It looks like 3 separate areas. First one small , last one small , and 8 in the middle is bigger area.

Edit/Update

I took some time and conversions to pick 3 areas while using your python script.
I put all 3 into OC config and now doing some more tests to check if its working stable and showing no more errors..
