Memtest 86 + errors found, how to interpret the results?

post #1 of 8
Thread Starter 
Hello,

I just ran Memtest 86 + from a usb for 1 hour and I found 128 errors, some on test #1, #3, #5 and #8. However I noticed all of them are almost on the same failing address it reads:

002d06axxxx - 11526.6 MB

The only thing that varied was the xxxx the other numbers were always the same, and often even the last 4 numbers repeated themselves. I have 16 GB of Corsair Vengeance of Memory installed, and I ran having all 16 GB.

I am no expert but it looks to me that if I have 16 gb, and it is always failing on 11526.6, does this mean that for sure the faulty RAM is in Slot # 3?. Also I don't think it is the CPU since if it was the CPU it wouldn't always be almost the same address, is that a correct assumption?.

I also read that I should run memtest 86 + with only one stick of RAM at a time. But my main concern is there a way to know for sure that the root cause of the problem is the RAM and not the Motherboard?. I am asking mainly because I have not experienced any BSOD of any kind, or instabilities, reboots, program crashes etc.

The only problem I had is while playing Starcraft 2, I got a corrupted files error twice after closing the game, and also once I saw bad graphics on a map. I was also getting low fps for my System on SC 2. Once my computer also restarted by itself, before even booting. So I guess the cause of those was the RAM?.

My real concern is how to know if the problem is really RAM, or the CPU or the Motherboard. I can run Prime 95 just fine although I only ran it for 1:30 hours, my Ram is supported by my motherboard and I have not OC'ed or modified timings, furthermore in BIOS the Voltage and timings are correct.

What other tests should I run?.

My system is:

Saphire HD 7850 OC (at default OC)
i5 2500k (turbo enabled, i.e. 3.7 ghz while gaming)
16 GB Corsair Vegeance @ 1333 (but can activate XPS for 1600 but would this really help at all?)
Maximus IV Gene-z/Gen 3 Motherboard
Blue Caviar WD 500 GB
Seasonic Semi Modular 620 W PSU

Thank you,

Oscar

The next step would be to run Memtest on one stick at a time, and use the same slot. If you get good and bad sticks in the same slot then it points to bad RAM. If they all work in a single slot then try them individually in the other slots - you may be able to pin down a bad slot.

Thank you for your answer I will try that. Hopefully it is just the RAM so it is way easier to just replace that, that is the more likely cause right?. My system is brand new, but is it possible the CPU could be the problem?, like it is not controlling the memory correctly?, I doubt so, but I don't know how to rule that out.

It could be the ram settings that are input in your BIOS.
Make sure the right values are set. You'll find the good ones on the side of any of ram modules.
They should look like 9-9-9-24 and a voltage.

Thank you for the suggestion, I checked my ram and timings and they are correct, I will test the sticks individually tonight.

Because your running 4 slots you might need up the voltage a tad on the ram and the mem controller.
I know it helps for amd, never worked on intel rigs

Mmm it is rated 1.5 V, running at 1.501, how much should i increase it?. Anyway if just 1 fails by itself that would indicate bad ram even if running at the 1.5 v right?

I finished my testing this is what I did:

I tested each RAM stick by itself on slot #1 on my motherboard for 2 1/2 passes about 1:10 hours. The first 2 sticks passed with no errors, however the third stick got 340+ errors in <10 minutes, so at that point I stopped the test. And just in case took one of the good sticks and tried it again in slot #2 and slot #3 for 2 1/2 passes and it passed with no errors. I did not try slot # 4, but I guess at this point it is pretty sure the problem is the RAM correct?.
