Just tested my ram with memtest86. Got about 24K errors but I don't have money to buy new RAM!!! I'm just 13 years old. Do you still use your PC if your RAM is dead? And how do I repair this RAM stick?
You can tell the Linux kernel to exclude some memory regions on its command line. Excerpt from the kernel parameter documentation:
memmap=nn[KMG]$ss[KMG] [KNL,ACPI] Mark specific memory as reserved. Region of memory to be reserved is from ss to ss+nn. Example: Exclude memory from 0x18690000-0x1869ffff memmap=64K$0x18690000 or memmap=0x10000$0x18690000
If you write down the exact location of the corrupted memory region from
memtest86+ you can then use that info as described above and add a parameter to the kernel boot options.
Be aware that memory corruptions can occur (apparently) randomly! Run the memory test at least twice to assure that the corrupted region is (most likely) always the same.
Once RAM fails, there is no real way to repair it short of remanufacturing it. If you use your computer with a bad RAM stick, you will experience odd lockups and errors at best. At worst, your computer will fail to boot at all.
My recommendation, if you have more than one stick of RAM in your computer, is to test each stick separately to narrow down which stick is giving you trouble. Once you remove that particular stick (if only one has issues) you will be OK. If you do this, just remember to take ESD precautions to avoid damaging other components. Otherwise, your best bet is to try to find a cheap stick of RAM on eBay or something.
