Nice to see this has been updated, finally. I prefer to use MemTest for Windows, though. From previous experiences, I have found it is more strict and will cause errors to occur faster than with the MemTest for DOS. That... and it runs in Windows, so it's a little prettier to look at.

I might download this MemTest86+ though and give it a test. It might come in handy for some upcoming DDR3 reviews I want to do.

I'll have to give that one a try, I've always used the boring DOS version in the past.

At least with the Windows version maybe I could play a game of cards or something while waiting.............:)

LOL, that's the thing. The problem is that if it's not a stable overclock, it could crash. If it's a borderline stable overclock, it will just show errors, which means you can finish up your game of cards (most likely).

What I really would like to find is some good utilities that work well under Linux so I can stay on one drive/OS most of the time.................;)

I really haven't looked around all that much for Linux utilities yet, mainly cause I'm still learning the OS, but the time will come.

I've never used a windows based memory testing app but I'll give this a try. Great finds guys.

Never knew there was a in-Windows based utility. Will have to give it a try as well... thanks for the update! :)

I am not sure of a GUI memory tester for Linux, but nothing stops you from installing MemTest86+ manually and being able to access it through GRUB. Most distros include it in their repository.

Essentially, you need to copy the memtest.bin file to you /boot folder and then add it to the GRUB configuration file. This way, you could access MemTest86+ anytime you boot up your computer. Instead of going into Linux or Windows, you'd select MemTest from the menu.
title=Memtest86 2.01
root (hd0,7)
kernel /boot/memtest86_201/memtest.bin
The above entry is just an example. It would vary depending on the real location of /boot.

Ubuntu 7.10 comes pre configured already with MemTest 1.70 installed in GRUB......;) I just need to figure out how to update it to the current version.............I guess I have a little reading ahead of me.

With any luck maybe the new version of Ubuntu comimng out next month will have the newest MemTest already installed as well.

If you have MemTest86+ burned to a CD already, just pop it into your PC when you are in there and see if there is a memtest.bin on it. It should be as easy as overwriting the copy that's already installed.

I just checked on the Memtest site and there's this ;

Download - Pre-Compiled Bootable Binary (.gz)

would what I need be in that DL??

Yup, it sure does. I downloaded it and extracted it, and it is indeed a .bin file:

memtest86+-2.01.bin

You could probably just overwrite the installed version of MemTest with this one, or install it as a second version. Finding out where memtest.bin is first would be a good idea. If you have slocate installed, you could just run that.
[email protected] ~ $ locate memtest.bin
/boot/memtest86plus/memtest.bin
You'd then want to copy the new version to the same spot.
techgage Desktop # cp memtest86+-2.01.bin /boot/memtest86plus/memtest_201.bin
I believe Ubuntu uses menu.1st for its boot loader, which is probably under /boot/grub/menu.1st. You could just edit that file, find the other MemTest entry, copy/paste it, and change the new entry to reflect the second copy (changing memtest.bin to memtest_201.bin and also the title to reflect the change).

OR, the new version might be available in the repository, but just hidden since it's unsafe. I am not sure how Ubuntu's repository works, though. Sorry if you are already aware how to edit GRUB, I'm just noting it in case you weren't.

I should have mentioned, sudo would be required for that since it's a sensitive system folder.

sudo cp memtest86+-2.01.bin /boot/memtest/memtest201.bin

That would do it. Again, sorry if you know how to do that, but I am not sure by your post, haha.

I'm not any good at all with the command line stuff, still trying to learn that as I go.

I found MemTest in the repository and installed it, but I'm not sure of the version, I guess I should reboot and check it out.............;)

Got it all figured out..........;)

Now I have memtest 2.01 on my GRUB boot screen.............:)

Thanks for the help.

Woo hoo!

Is that seriously the default GRUB Ubuntu uses? It doesn't even have a background graphic! Talk about living in the stone age.

Yup, that's the way it comes, I wouldn't mind trying to change it somehow, but seeing as the new version is coming out next month and the beta this week, I may just wate to see what they look like.

Implementing one is simple. You just need to download a splashscreen graphic... here is a good site.

The graphic file itself will be either a .xpm or inside of an archive (xpm.gz). Once copied to your /boot or somewhere else, you could edit your menu.1st to include it. Here's an example from my file:
timeout 15
default 0
splashimage=(hd0,4)/boot/grub/splash.xpm.gz

title Gentoo Linux (2.6.24.2)
root (hd0,4)
kernel /2.6.24.2 root=/dev/sda9
