Help me read Memtest failure

[wb123]

Here are the memtest results.
can someone help me diagnose which memory stick to pull ?
What do these results suggest?

Computers seems sluggish at times as well. Not sure if it has to do with memory issue.

Here is my memory timings.

Everything is set to auto. Not overclocked.
CPU is AMD FX 8350

Just have to try one at a time and see which doesn't give errors.

Also, if you get unpredictable results where sometimes a given ram stick will pass or fail, and the other stick will similarly pass or fail over time, then you might have an issue with the CPU and its memory controller. Try underclocking and boosting voltage to the CPU memory controller.

Some Dimms also require a higher voltage as well, you don't specify what kind, and what voltage you are running through them.
What motherboard is this as well?
Also, try memtest86+

core voltage fluctuates based upon system load.

Mobo m5a99x evo 2.0

No error messages when 1 stick at a time.
the only an error message populated during the test was when i had all 4 sticks plugged in.

there have been times where the 4th stick does not pick up and it just thinks 3 sticks of ram are slotted.

you likely need to adjust your timings a bit
what voltage are you running them at ?
there is a good chance the "auto" is not correct

 

[Elixer]

Yeah, if the stick checks out OK (though, to be honest, you should be testing each stick overnight, not just 1 pass) then you usually need to pump a bit more voltage, but, again, what RAM are you using, and what voltages are they rated for?

As Soulkeeper pointed out, this is not a good sign. The motherboard may get into trouble when auto adjusting voltage and timings for RAM modules with different specs.

Don't bother debugging the memtest error output! You can't figure out the bad module by debugging memtest errors.

1. First, make sure that all modules pass memtest without a single error! The number of full memtest passes is irrelevant. It's more the overall run-time of memtest that assures the most confident result.

2. If you're using different model/manufacturer modules at once try this:
2.1 Use cpuz to read the spd data/specs(spd voltage and timings) for all the modules.
2.2 Use BIOS. Bump up the memory voltage just a little over the lowest commom/mutual voltage identified with cpuz.
2.3 Use BIOS. Identify the lowest commom/mutual timings between all the modules and increase them a little(by +1 or +2).

2. is what others had already suggested, maybe just in a more detailed manner.

ok great
thank you very much everyone!

That does NOT show who made the RAM, and the voltage...

everything seems to run now fine at 1333 dual channel mode.
I apologize, before i had everything set to 1600

Still it should have worked at 1600 since it's rated for it.
