Memory test error feedback


I have ran the simmtester memory test on a few pcs same spec built by the same company, i will be testing the rest.
I have tested 3 on one this is the fail results I get.

This is actually my system..

MARCH B.  >>ADDR, (87M) EXP: 33cc33cc, Act: 33cc33ec.
MARCH c-  >>ADDR, (10M) EXP: 33cc33cc, Act: 37cc33cc.
Burst         >>ADDR, (40M) EXP: F0F0F0F0,Act: F0F0F0F2.
Checkeboard   >> ADDR, (10M) EXP: 33cc33cc, Act: 37cc33cc.

Is this defective memory, plz explain the results..
Does defective memory cause bad blocks on Hard disks?
Would you suggest reseating the memory??

Thank You..

Hi 1stITMAN,

> Is this defective memory, plz explain the results
Yes, you can see that easely:
EXP means what is written to the memmory, Act is what is read from exactly the same location. They should be the same.

> Does defective memory cause bad blocks on Hard disks?
No, but crashes from bad memmory can cause corrupted data on the disk drive.

> Would you suggest reseating the memory??
I suggest you use the memmory as a frisbee in the direction of a garbage bin.

Another system has failed the test on
BURST >> ADDR, (203M)  exp: 00000000  act: 02000000.

Thank You LucF..

I thought the same, well they are new PC's from a company we get them built from so they are still under warranty..
I will be speaking to them..
I have one hard disk from a system telling there results from SMART that it was gonna fail.
Now Ive changed my system for a newer one and memory errors ahhhh.
Had another system showing bad blocks on Hard disk... got that changed.. Same system had memory errors similar to above.

On the system showing these errors I had no crashes or blue screens running really smoothly???
so what do you say?
LucFEMEA Server EngineerCommented:
That you didn't have BSOD's etc is just plain luck.
The memmory locations that give errors where'nt used intensively it seems otherwise you whould have noticed it right away. I've seen systems running stable with more than 20 memmory faults, still... some day it'll give you a crash (and that'll always be on the moment you forget to save your 50 page document :()

Thanks again,

My IT Manager wants to know if the software is reliable I know it is??
I am curently using the latest version and it is BETA test one is that ok?
LucFEMEA Server EngineerCommented:
Hmm as it's a BETA, I suggest you to try some other tools also.
Could be the BETA-software is a bit buggy.
Zaheer IqbalTechnical Assurance & ImplementationAuthor Commented:
Its Version 2.2..
Zaheer IqbalTechnical Assurance & ImplementationAuthor Commented:
I have tried that just now memtest -86 v3.1  and the errors are far worse.
13 errors in test 3 and 1 error in test 4.
Ahhhhh ahhhh what happenin..
It a bit more complicated to understatnd this one..
Tried on a system that passed with Docmemory, memtest discovered 2 errors..
LucFEMEA Server EngineerCommented:
Are you sure the memmory in those systems is compatible with the motherboards?
Either if it's incompatible or faulty. Replace it. I 100% trust memtest86. If that one sais it's faulty, believe it, it's faulty.

Ok well the systems were built by a uk company ill be giveing them a call.

Thanks again..

Ive sussed it myself well you learn summat new everyday. It was actually a setting in the BIOS to do with DRAM control which was set to ULTRA MODE that was causing the problems..
