Memtest86+ 1.00

Posted on Monday, January 12 2004 @ 22:13 CET by LSDsmurf

The first version of Memtest86+ was released on early 2004, based on memtest86 v3.0 that was not updated since mid-2002. Our main challenge was to provide an up-to-date version of this useful tool, as reliable than the original. Our work started when we got the first AMD64 system. Unfortunatly, the original memtest v3.0 didn't run at all. After looking at the source code, we fixed the bug.After some days, I saw lot of other things like chipsets or CPU that were not correctly detected or not detected at all. As I'm the chief-editor of a french hardware website (, I have access to lot of recent hardware and I can test and debug on quite all available motherboards on the market. After adding detection for all current CPUs, I've added detection for all current chipsets (SiS, VIA, nVidia, Intel) and ECC Polling for AMD64, i875P and E7205. Then, I decided to display some useful settings for the most popular chipsets. For exemple, on i865PE/i875P series, memtest86+ will now display FSB & Memory frequency, PAT status, memory timings, ECC status and the number of memory channels. Next version will perhaps contain several enhancements and bug-fixes.

Enhancement in v1.0 (Based on Memtest86 V3.0) :

  • Lots of bug-fixes, works now with all AMD64.
  • Added detection for Athlon 64 / Opteron
  • Added detection for latest Athlon XP (including Barton)
  • Added detection for latest Pentium 4 (including Prescott)
  • Added detection for SiS735/740/745/748/755/645/655
  • Added detection for ATi Radeon 9100 IGP (RS300)
  • Added detection for nVidia nForce/nForce2(400/Ultra)/nForce3/nForce3-S
  • Added detection for VIA KT266(A)/333/KT400(A)/KT600/PT800/PT880/K8T800
  • Added detection for i865P/PE/G/i875P/E7500/E7501/E7205
  • ECC initialization & ECC polling added for all AMD64 CPUs
  • ECC initialization & ECC polling added for i875P and E7501 & E7205
  • Added complete advanced settings detection for i875P, AMD64 and nForce2.
  • Added partial advanced settings detection for KT266(A)/KT333.
  • Corrected ECC Error not counted as a global error anymore.
  • Added a "safe-mode" (press F1 when memtest86+ loading) in case of freeze.
  • Source code now compatible with gcc 3
