Memtest - Error Confidence Value

[bokrael]

Hello. Ive just bough these RAM kit second hand. The computer started normaly but I run a memtest and it shows me this. Should I get my money back or this can be non faulty RAM?



That is my motherboard.

The value starts from 127 and keep growing. Im doing the test with both Ram's at same time.

Update.

Let memtest86 run for a few hours / 10+ complete passes and see how many errors you get.

If the same bits at the same subset of addresses keep generating errors, then you know with reasonable certainty that those bits are indeed bad. If errors jump around in bits and addresses, then there may be some other issue such as with timing margins or signal noise on the motherboard, try knocking the memory clock one notch and see if that fixes those.

The only acceptable result on memtest is 0 errors. I wouldn't trust memory until it can achieve that over a 10+ passes break-in.

So I better return it? I also would like to run with no errors?

As I already said, the only acceptable result on memtest86 is zero errors.

What is the newest x64 version of memtest and where I can download it?

... first result...

It got a whole lot fancier since the last time I've downloaded it.

Already did that. But the READ ME file in this:

MemTest86 V7.4 Free Edition Download

Says thats is x32 version. Can I use it with x64 system?

System Requirements
x86 based hardware, 32bit or 64bit
UEFI or BIOS platform firmware (UEFI required to boot V7)
Windows, Linux, or Mac OS
CD or USB Flash Drive (>= 256MB capacity)

What this suppose to mean??

There is no x64-specific version. It boots as either 16bits (legacy) or 32bits (UEFI) then switches to 64bits if available.

The memtest version isn't relevant. You could try lowering the ram frequency in the BIOS and running the test again. Any error in ram is unacceptable. Run at lower frequency or return.

Strange. I downloaded memtest86 7.4 and burn it on cd, but when I boot it it shows it's version 4.3.7?!?! Is that normal?

As long as it works the version doesn't matter.
