Memtest86 Results Help

[Liam401]

I have been experiencing a lot of blue screens lately, some which described memory problems so i looked up a memory test tool. After running the memory test with all 4 sticks of ram i got this as a result. Can someone please explain what the 100k+ errors mean? Thanks in advance

Those are a lot of errors, it just means a certain size memory transfer was not successful.

Makes sure your RAM is seated properly(remove it and return it).
Then if you are still getting errors, try one stick at a time to find the faulty one.

What mobo, CPU and what sticks of DRAM do you have, were all 4 sticks in a single package or is this just mixed sticks...with Memtest always best to test a single stick at a time, running on multiple sticks at once in itself can cause errors....should be good only running 3-4 passes on each stick (otherwise it takes forever)

incorrect.

run memtest with all sticks at once *initially* - if they dont want to co-exist and it fails memtest then that WILL cause problems not just in memtest

to narrow down a faulty stick you run memtest with one stick at a time

if they all pass independently you car try lowering the speed and raising the voltage 0.1v more and re-running memtest with the lot

the golden rules with ram is 1) least amount of sticks and 2) most matched


other things to conciser:
crashes and reboots caused by memtest can corrupt the file system and one some hdds it will actually mark sectors bad (1 pending) - check and repair the file system where necessary, also check and repair hdd as necessary

if the ram problem is resolved and your still getting a bsod it could be from the corruptions and a reinstall may be required

Beg to disagree, running all at once does nothing to determine if a stick or sticks are bad, which is why you test each individually...running multiple sticks can get errors from bad timings, either base or advanced (very often with multiple sticks, especially tRC and tRFC), bad voltages even the wrong CR - NONE of which means you have a bad stick or sticks. SO especially if running the full array of Memtest you have now wasted hours to accomplish absolutely nothing.

By running each individually at base timings and voltages actually test the individual stick to determine if bad.

If all pass independently, then you ensure they are set up correctly and that you have the latest BIOS (as upwards of 50-75% of all BIOS updates are specifically for DRAM) - If using mixed sets then you need to ensure the advanced/secondary timings are within ranges for the mixture of sticks....and then try at stock voltage....

If still problems you next try and adjust for voltage.......BUT you NEVER jump sticks +0.10 at a pop, most sticks are only recommended for a + 0.10 increase, a good place to start is + 0.05 with sticks 1866 and under and based at 1.5, 2133 and above stick with base recommended of 1.6 or 1.65 you start with an increase even lower + 0.03 and if needed you should balance this out with a small and then incremental increase to the MC (memory controller) voltage.....and while on the subject, it's never a good idea to mix sticks....period....

Hey, thank you for reply. The ram sticks are all the same, 4x 4gb 1600mhz corsair vengeance. CPU is amd fc 8120 and the motherboard is a gigabyte 990fxa ud3 skt. I'm going to run the individual tests later on when i get the time.

Are they all the same model? With the weaker MC of the AMD and 4 sticks may simply want ot raise the DRAM voltage + 0.05 and then take the CPU/NB (MC (memory controller)) voltage up + 0.075 and give that a try

Yes they are the same i bought the ram as a kit came with 4x4gb sticks i finished testing my first stick it was the one furthest away from the CPU and it passed no errors found and i did 3 passes on it going to be doing the others
when i can.

Well i just finished doing all tests found out that one stick was the problem i have removed it but I just don't no what to do now
