Hi Newbie question sorry but how do I install memtest on a BartPE usb drive I created? Any info or guides appreciated, many thanks. R.

Hallo, I have strange errors when i Test my ram... When i go for over 6 or 8 hours every single adress fails! there are over 50 000 errors... My System often just BSOD'S randomly...

Hello. We experience problems with PC2100R DDR/DIMM ECC (registered) memory modules inserted in DELL PowerEdge 600SC server. It doesn't matter how many modules are inserted ... memtest always shows errors near the very last address (approx 300kB from the end of the available address range). The errors appear almost immediately after the start. The memory seems to work correctly (the system is stable). I believe this must be some kind of memtest bug. Please, let me know what debug...

I have modified the old style zImage to bzImage. This will load the test program in high memory. Linux already using this model from many versions. A grub entry similar to this will be able to load new bzImage instead of using linux16. menuentry 'Memtest memtest32' { linux /memtest.bin } Where to send this change for review and inclusion to next release? Thanks,

Im having a strange problem and I cannot seem to wrap my head around this at all. For some reason.. I am able to do memory tests on all other motherboards except for this motherboard.. it just makes no sense.. Ive tried new ram.. swapping them back and forth even testing all four ram sticks one by one four times for four dims. So ive taken ram stick 1 and put it in dim on.. test.. froze.. Ram 1 dim 2,.. ram 1 Dim 3.. ect and so forth and working my way up again with the second and third...

I've been reading the FAQ and forum trying to resolve my issue, but I could use some additional help. On a consistent basis, my computer randomly BSODs after several hours of activity with memory errors. It normally takes 4 to 8 hours to see the BSOD come up. I ran memtest86+ when I built the machine, but it came back clean. I decided to do a new run of memtest86+ 4.20, but run it for 4 to 8 hours. Low and behold, after several hours and many error free passes, I start getting...

1. "Move inversion" should be MATS+ 2.Background patten's generation should be more scientific. 3.More march test should be added like march c-/march LR

Hello, i did not find the answer to my question so here i am. I am running memtest on my new desktop from usb and i find its behavior strange. For one 8go stick (ddr3 pc12800) : - the first pass takes ~30 min - the 2nd ~1h20 - the 3rd even longer Is it the intended behavior ?

I recently ran Memtest86+ for the first time as part of an Ubuntu install, out of curiosity, and after about 10 minutes, Memtest86+ started rapidly counting up errors (sorry, I didn't note the exact spot in the test), and after an hour or so, it was up in the millions. However, I've been having no problems with my laptop. I did, however, recently purchase new RAM, which is why I was curious to try Memtest86+. So after getting these errors I tried Memtest86+ on my previous RAM module, and...

Any of the v5 betas (v4 works fine). I can't boot the .bin my my grub boot loader or boot from usb. Burning a DVD works but I dislike doing that.

I am experiencing no errors with the latest memtest86+ but when I use the latest memtest86 version I get plenty of errors. Which one should I trust ? This should not happen. I have ran both programs several times and always get the same difference in error reporting which I consider surprising. Looking for your feedback.

Hi, I have a problem using the latest version of memtest 4.20+ or the current b-version. If I start it on a board with Sandybridge-CPU (i7-2710QE) and 2*8GB (PC3-12800) memory using internal VGA, I will get a black screen after up to 72 hours. Theboard still runs, because I can restart with <ESC>. Whenever I looked,it happened in test 8 and a video suggests, that the video RAM is overwritten. When I use an external graphics card, I had no error in 5days. I made another more...

Hi NG, I'm loading memtest86+ 4.0 with kexec. This is working fine as long as I'm running in 25x80 Textmode. When I switch to some graphical mode, the screen becomes black, but memtest is running silently... Is there any posibility to switch back to textmode before running kexec? Is there any posibility to initialize vga in memtestimage? Is there any posibility to switch back to textmode with kexec? Or does anybody has a different idea/solution for me?

Running v1.70 shows permanent errors on Failing Address 00000000000 - 0.0MB with Bad always 00000000 on tests 3, 4, 5, 6 and 7. Running v4.00 shows no errors. Details of the hardware: 1GB RAM, CPU is AMD Turion 64 Mobile MK-36. Which version should I trust ? Memtest86+ v1.70 shows these hardware details: Athlon 64 (0.09) 2000 MHz L1 Cache: 128K 16393MB/s L2 Cache: 512K 3906MB/s Memory: 990M 2111MB/s Chipset: AMD 8000 (ECC : Disabled) Settings: RAM : 285 MHz (DDR571) / CAS : 4-4-4-12 /...

I am building a new system using Corsair memory(2x4gb), on a Gigabyte GA970A DS3 / AMD FX-6 6200. The memory sticks fail individually or as a pair on test 7 when running memtest. The BIOS is set to AUTO, and is presently running the memory @ 1333/1.5V, which is the default spd value. I don't know enough about memory faults or results like these to know what's going on, can anyone help here please?

What is the maximum RAM size can to check it? I need to check 256 Gigabytes RAM in server. Can I do this with " Memtest86+ V4.20"?

Hello, I've got a - more or less - weird problem: Windows 7 produces blue screens during install, or .net assemblies stop working from one second to another, or it logs lost memory messages to its syslog. On Linux processes segfault from one second to another, I can see memory errors in dmesg and so on. As all this happens inside a VM, I decided to run memtest on the host and inside the VM.

Hello i have been running memtest86+ for 24Hours with a 24GB (6x4)kit . It has 6 passes no errors should i stop testing,am i O.K.?

Hello memtest86+ experts! I've purchased an Asus M4A785TD-V EVO/U3S6 Mainboard and installed 8 Gbytes of PC3-10600E Memory (2x 2 Gbyte DELL 2Rx8 Modules and 2x 2 Gbyte Hynix 2Rx8 Modules). If I run memtest86+ without ECC support enabled in BIOS the test passes with no errors. When I enable ECC support in BIOS, memtest86+ shows several errors (not ECC errors!). As there are more than 40000 errors shown I doubt a failure of the RAM-modules. May it be a bug in memtest86+ ? Thanks for your...

I ran the test on my computer, the test finished with no errors. Now i cannot get the computer to reboot into any mode, bios, normal or even back into memtest??

Hey, I have a laptop which has integrated onboard ram. No traditional memory slots for ram. I ran Memtest v4.2 on it and it came up with over 40 000+ errors. Can the newest Memtest come up with accurate results with onboard ram or is it a possibility that it's a false alarm? Thanks.

Hello all, I've read the FAQ, and browsed the forum, and haven't found anything quite similar to this post, so hopefully someone can help me troubleshoot this, as I'm pushing the limit of my hardware knowledge. I ran memtest for fairly obvious reasons and found several errors. Ok, RAM could be bad. But how can I determine if it's the MB or the RAM? I pulled one of 2, 2GB sticks, and ran some apps and they worked without crashing so I thought I had the culprit, but ran memtest again on...

In my HP Pavilion G6-1c35dx I upgraded my ram from 4gb to 8gb by adding a 4gb SoDIMM PC3-1600 RAM chip by PNY. There are two slots on my notebook, only one was being used stock so I just plugged in the other. After I installed it though my windows became really unstable but, my ubuntu 12.04 (on another partition) ran perfectly fine and reported the full 8gb of ram. Back in windows, I managed to get 3 memtests running (since it said I needed to run multiple instances) and 1 of them...

First, thanx for memtest86+ Doc! It's a great tool. Platform: Supermicro X7DB3 motherboard with Intel 5000P chipset Memory: DDR2/667 fully buffered ECC I attempted to answer this via a search of the forum and Google; perhaps my Google-Fu is weak. My question is regarding the "ECC Errs" column; when running a test on the above hardware, with the ECC setting set to "Recommended", three passes showed no errors and the space beneath the "ECC Errs" column was blank. Upon rebooting the...

Hello, I just decided to upgrade my Dell Studio 1558 laptop with a 8GB memory Kit (4GBx2) reference CMSO8GX3M2A1333C9. The memory size is recognized within the BIOS but I'm not able to start Windows. It just asks me if I want to repair it or start windows normally. Every time I try to start Windows normally it just reboots itself. Mixing old and new memory modules does not work. Using only one memory module does not work either. When using the old 4GB memory Kit (2GBx2), everything...

Sorry, found the answers I was looking for. This was a bug with the Memtest86+ version included with Ubuntu 12.10 Please feel free to delete this thread, mods. Thanks!
