Memtest86+ V2.00 (08/02/2008)
- Thread starter NoobyDoo
- Start date
I downloaded this and am having problems running it with a floppy or usb pen drive?
Both seem to have made the disk ok but when rebooting it will just go past the floppy boot or usb boot right to Vista 32? As is says on the readme it doesn't show up anything in windows? Anyone else have this?
Also running the Vista 32 memory check you can go in in the vista start window I get errors when 4-1G Ballistic sticks are in but with only 2 sticks in I am fine. Don't matter which 2 are in they check out fine, just when I use 4 it gives errors. I am overclocked as you can see in my signature so tonight I will go back to stock and check again. May just be pushing the memory too much. Just kind of strange with 2 sticks its ok?
Thoughts?

Let me guess, it still lacks 64-bit support, so it can't test more than 3.5GB worth of RAM, right?
When I run it from the floppy, the words are cut off on the left side of the screen i.e. I see "el" instead of "Intel". Anyone else having that problem? When using v1.70, all is well.

Alright... hummm... so I downloaded from Guru3D, and I had two archives, one contained an .ISO, and the other contained an .EXE named mt200. Now I want to remove mt200.exe but it says that it is being used. I tried to remove it in Safe Mode and it refuses to go.
why 3.5gb? isn't that a windows problem? doesn't memtest86+ not relate to windows at all and boots off a CD?

No, 3.5GB (approx) is the limit of the 32-bit address space. It has to fit hardware I/O in there somewhere, so that leaves less than 4GB for RAM. So you need 64-bit mode to access mode. Hence my question.
good heavens, if memtest lacks 64 bit support then do we have to test each module separately when using 6 Gb of RAM?

No, it will test all 4+ GB, but it has to do it in portions, instead of simultaneously.
For this reason, i am finding Memtest86+ less of a viable stresstesting tool.
I have found that HCI Memtest, which is run in Windows, finds errors or instability much faster usually, since you can run as many instances as needed to simultaneously stress ALL your RAM.
It also tends to show NB/MCH instabilty because of that as well, since if you're running 4 dimms, it puts tremendous stress on that.

Because of this, I don't find this very good. Running four instances will only test 4GB.
If you want to test memory for errors, that is all you should be stressing! Verify that the MEMORY ONLY is good, then go on to other testing. Sometimes a bad module that will not run at stock speed and stock voltage could be holding you back and you would not know it.

I concur, HCI is great, I've used it a lot to troubleshoot with my previous 2GB kit.
Now that I've got two sticks of 2GB each I've noticed that Memtest86+ will do each tests two times instead of one, for example, with my previous kit it would do each tests in chronological order, but only do them one time until the last test, and then loop all of them from the start again, and so on. Now with 4GB the loop works, but each tests are done twice, thus taking twice the time to complete a single pass.
With HCI and 4GB I can manually adjust the desired amount of memory I want to test, in fact I can test so much that it some times also test the actual paging file (if I put a large number going above my physical RAM), which stresses the whole system instead of just the RAM. That way other issues will be detected in the process such as n7 said. It's a test under the Windows environment, so any NB/FSB-related issues will pop up to HCI and it'll in turn give you errors fast enough. Basically if an HCI test passes without errors it is a very reliable result, if not better than Memtest.

n7, memtest86+ is NOT designed to stress RAM, just test it thoroughly under fairly normal conditions. Thus, as you say, it's more of a floor on which to add stress testing.
