I've just bought new RAM (SDRAM PC 133) on a web site.
I've made a test with Memtest86+ 2.1 using a bootable CD and after 30
minutes (4 pass), there's just one error.
What do you think about it ?
It's completely unacceptable, especially because even MemTest86 is a
lot more lax than the testing machines used by chip manufacturers like
Samsung, Micron, etc. And you need to test for a lot longer than 30
minutes, like overnight, because I've had modules run fine and then
show errors after 4-5 hours. I'd also try Gold Memory ver. 5.07 (not
just 6.xx) because it often finds errors that every version of
MemTest86 misses.
If the dealer won't provide you with a 100% good replacement at no
charge to you, including return shipping, then you should _mail_ a
written billing error complaint with your credit card company at the
special billing problem address. Mailing the complaint obligates the
card company to act as your collection agent and make your bill right,
even if it can't collect from the merchant (something that card
issuers often don't like to admit or will outright lie about).
A lot of memory modules are junk now, including many major brands.
About the only way to avoid junk is by purchasing modules made with a
chip manufacturer's first-rate chips, meaning they're marked with a
full part number that can be Googled and return dozens of pages of
specifications. Also avoid modules with heatsinks on them or that
require a nonstandard voltage (i.e., not 3.30V, 2.50V, 1.80V, or
1.50V)
