Forum: Memtest86+ Official forum

OK go easy – I am NOT a computer guru so will have to do this one slow sloppy step at a time. Yes, I have read as much as I can absorb from the memtest site and this forum but I am still a bit turned-around. And yes, every driver and the BIOS are current. Let’s start with the problem: And here is an outline of my system which I built mid-SEP 2011: PROCESSOR: Intel Core i7-980 Gulftown 3.33GHz LGA 1366 130W Six-Core Desktop Processor BX80613I7980 HEAT SINK/FAN: Cooler...

My pc freezes on the windows start up page, I am running XP Pro, I have tried re-installing windows on another hard drive but when it gets to the first restart my pc does not restart. I have tried installing both XP Pro and 2000 pro, pc fails to restart at first resart point of install, fans keep running at restart. I have tried both SATA and IDE drives, and it happens on both drives. The pc use to work, I moved to the USA for a year and then back to the UK shipping the PC with me, I...

Hello. I got strange results when tested ECC memory: 1) there were no errors with BIOS ECC switch disabled; 2) there were errors with BIOS ECC switch enabled. Can anybody explain me this behavior? Are my memory modules good or with defects?

Ran Memtest and Rember on Mac. Both caused computer to freeze. Ran Memtest86+ (4.2) and it ran without any errors through 20+ loops. Given these conflicting results, don't know whether I have bad memory or not. Any advice?

Read the very first post on this forum and the very last post describes my issue. I downloaded the the zip for windows and unpacked the zip. Ran the executable with a check mark to format the stick. The process runs very quickly and states its complete and the stick should be bootable. This is done under windows XP SP3. Take it to a laptop and try to boot. It says the Operating System files are missing. This is an older laptop that I'm trying to boot. As I power up machine I press f12 to...

Running it from a USB stick on a Thinkpad W510 with 16GB Ram. Consistently crashes around test 7, but it runs fine in fail-safe mode. No errors being reported in fail-safe mode.

Hello I am new here just on retirement and am just getting into computing in a little more depth, and maybe some O/Cing. I have a problem with a desktop with a slow booting / loading SSD and after many attempts at finding the cause am now on my last trial - memtest to see if the RAM is holding things up. Problem is it is running and I have no idea of how long to run it - have seen some say hours etc and when it is finished I really will not know how to tell if my RAM (G-Skill 16GGB ...

Hi, I have a problem with Memtest86+ v4.2. The moment I start it - it reboots my PC. The system is: Gigabyte P67A-UD3-B3 Motherboard with BIOS version F9 The memory is: 2xKingston KHX1333C9D3B1K2/8G kits (2 kits of 8GB, 4 modules of 4GB each) = 16GB total. CPU is i7-2600 @3.4Ghz

Hi there, I had an issue on a DELL R610 Server with 4x4Gb of ECC RAM. This machine is running under debian linux and was filling /var/log/messages with : Apr 25 18:24:37 imu253 kernel: MCE: The hardware reports a non fatal, correctable incident occurred on CPU 3. Apr 25 18:24:37 imu253 kernel: MCE: The hardware reports a non fatal, correctable incident occurred on CPU 5. Apr 25 18:24:37 imu253 kernel: MCE: The hardware reports a non fatal, correctable incident occurred on CPU 6. Apr...

Hi: I ran a memory test and failed test case 6 - moving inversion. The error bits are 04000000. The test case generates an error at every memory address. It is not very possible that my memory has a problem at EVERY address. Therefore, I'm suspecting there's some systematic error that affects every memory inversion operation. I guess maybe there's a problem with my mother board or bios? But I don't know how to proceed from here. Please let me know what you think and what I may want to...

Hi, It was recommended by a support person at VMWare that I might have memory issues that causes the VM to crash the Mac at random times.. Memory was installed by Certified Apple vendor at purchase. I downloaded the memtest86+-4.20.iso.zip and created a boot disk.. Upon booting to that disk it comes up, starts to test and then crashes.. with "Unexpected Interrupt - Halting" Hardware Overview: Model Name: MacBook Pro Model Identifier: MacBookPro8,2

help! i did as the guide suggested and installed memtest86+ on a usb drive. i even tried version 5. i'm running off just the mobo, cpu, and ram. no disk drives are on the board since i heard it doesn't matter, and i know the bios is recognising the fdd because it says "no os detected" when the usb key isn't connected, but when it is connected it says "loading operating system". but it loads for a while then just says "boot error"... processor: fx 6100 mobo: 970A-DS3 RAM: 996995 Mushkin...

I ran memtest last night. I have six modules DDR3 X 2GB each. It gave results which confound me totally! It gave memory slots numbered from 0 to 15 and said that errors were found in modules 1,3, and 5. It also said that the lowest memory failure was at 2425.2 MB and the highest at 9204.2 MB. None of these mean ANYTHING to me in trying to find WHICH of the modules is not working correctly - for possible RMA. Thanks.

I am using a new (to me) motherboard and not getting any love from MemTest: Supermicro X9SCL-F-O (Chipset Intel C202 PCH chipset) Ram: Samsung DDR3 - M391B1G73BH0-CH9 Samsung DDR3 - M391B5273CH0-CH9 Is it the motherboard chipset or the ram that isn't supported? I get a blue screen with just memtest in the upper left... And I just donated $40 via paypal to the memtest86+ project because I love you! :wub:

I'm happy to announce Memtest86+ V5.0 just leaved the alpha stage and is now beta, after months of debugging (u enjoy screen corruption, ya ?). Expect awesome stuff like complete support for new chipsets, new monitoring features, advanced faults detection, 64 bit mode for up to 2 TB of memory and SMT support up to 32 cores. Will post a screenshot asap. RC expected before the end of the month :)

Hi, I'm running an old comp.. P3 800MHZ, Intel Mother board, 256MB + 128MB SD RAM(This may shock some but I deliberately still run this fossil because it keeps my gaming addiction in check). A few weeks ago, I started getting BSOD with the page fault error. I first thought it could be a virus and scanned, but couldn't find any. Then I thought maybe the OS got corrupted and ran a Repair install(I have XP), when that failed I formatted my entire HDD and installed a fresh Win XP, but the...

I was hoping someone could explain to me why Memtest86+ has to be updated with the release of each new processor microarchitecture. An example of a microarchitecture would be Intel's Sandy Bridge. It's my understanding that all x86 microarchitectures implement the same basic x86 instruction set (though new instruction set extensions, such as SSE, are added overtime). As such, new x86 processors should be fully compatible with all old x86 programs. Why then does Memtest86+ refuse to run on...

I run memtest86 today and my ram always failed at the same exact point (11831.9 MB ) I have total 16gb ram and as i see failed part of my ram is less than a 1 MB. Are there any way to ignore or do not let my OS touch this part of my ram ? By the way i am using win7.

Hallo all! Since yesterday my laptopcan't startup Windows anymore. During loading Windows it gives a blue screeneven when starting save mode. Differend fault codes accrue. Some are memoryrelated. I'm currently running Memtest (see screenshot). It found a lot oferrors. Is the RAM damaged? Thanks!

Hi, Any further news on MemTest86+ v5.00? There was an announcement here some time ago about the alpha version and since then there has been no further announcements or news. What have been the challenges for this release? Any interesting bugs found or new features added? :-) Kind Regards

Hi, I want to know if it was possible that the Memtest CD is automatically ejected after being loaded into memory or after making a pass. Is there already a solution, or should one recompile an unofficial memtest ? Votra thank you for help! :rolleyes: (Sorry for my bad English...)

I need to verify RAM validity on an ASUS P9X79 PRO motherboard (Sandy Bridge-E). My question is, is memtest 86+ 4.20 safe to use on this board? I have used it; it seemed to work OK (though not all 32GB showed up, only 24GB; but the BIOS showed a problem with the last 2 sticks as well (of 8 sticks in total); these symptoms may or may not be related). The CPU was reported by memtest86+ as "Pentium M". It is a Core i7 3820K. No RAM errors were thrown, at least up to near the end of...

Hi, I downloaded the Auto-installer for USB Key (Win 9x/2k/xp/7) (http://www.memtest.org/download/4.20/memtest86+-4.20.usb.installer.zip) and installed memtest on a 1 GB USB-stick. I let the tool format my USB-Stick with used FAT32. After booting from the stick I got an error that the kernel wasn't found. After checking syslinux.cfg without finding an error I formatted the stick with FAT (not FAT32) manually and installed memtest with the tool again without formatting it. Now it works....

Ok, so I ran the memtest (USB version) For three hours and it wouldn't do anything but sit on 80% and not complete a single pass.... Is there something wrong if it sits like this or is it supposed to take forever like this? At a rate of 3+ hours and not a single pass for me, I can't see how some people managed 7 passes in a 8 hours time period... There is still a blinking cursor from memtest, but the keyboard doesn't respond to exit the scan so I have to shut it down by the button. ...

I see on Memtest86.com that they are releasing version 4 shortly (beta 2 currently available). It is apparently a major rewrite containing substantial code cleanup, large number of minor bug fixes, re-organisation of the code, and among other things 'Support for testing with multiple CPUs. All tests except for #11 (Bit Fade) have been multi-threaded. A maximum of 16 CPUs will be used for testing.' I am wondering whether a later (but soon) release of Memtest86+ will incorporate these...

G'day all! My mums computer has been shutting down regularly ever since I installed some DDR2 ram. I am currently running Memtest on it and am getting heaps of errors during test 8 on CPU "0". This is my current screen 20mins into testing: Does this mean my CPU needs replacing and it may not be a RAM issue? Thanks, Mark (Australia)
