I would try each/both RAM modules in a different system...and then run a memory diagnostic...before concluding anything.

What should I do if I don't have a different system? I tried the working stick (#1) with memtest and it was fine

You have no friends with systems?  You have no systems at your workplace (assuming that are still part of the working class, unlike me)?

 

The switching of a RAM module...only takes a few minutes to see if the module works properly in a different system utilizing the specs for said module.

Well...now that we know that module is not defective...it would seem that your system is not functioning properly. 

 

I would remove all modules from the motherboard...and then ensure that there is no dust or other material in the RAM slots which might hinder/impede proper performance.  Then I would try each module individually in the first RAM slot...to see if system boots properly. 
 

If so...then try the next RAM motherboard slot in the same manner.

No idea, plugging in the #2 ram in any slot causes no display while on a different PC it works fine.

My self id RMA is if i could, should work out of the box, and your ram should be in dimm #1 and #3 or #2 and #4 if you go #1 and #2 or #3 and #4 its not in dual mode.

some things we can do though if you dont want to RMA and that is run the memory in safe mode for testing.

 

Use one stick of ram just to boot computer then go right in to the bios.

Dissable serial presence detect (SPD) do all settings by hand.

 

voltage 1.9

Timing 5-5-5-18 change to 8-8-8-25

memory bus speed -50% so if you see 400mgz in bios make it 200mgz if its 200mgz drop to 100mgz etc.

no need to mess with the rest of the low level memeory settings/ leave on defalts.

 

Save and exit, now mess with your memory sticks, and remember you have 4 dimms on that mobo so 4 places to put your ram.

Depending what dimm you use it will be in dual channal mode or not but should still work.

Run Memtest86+ with just the one module.  One complete pass takes close to 3 hours.  If any error occurs, stop the test and contact the seller for RMA procedures.

You say these are used modules...maybe "used" means "not working properly" to the seller.

if RAM stick does not work than it's rather easy... RAM sick #2 simply does not work it is mostly a dead ram stick

I had a unit come in once, and it took me a while to figure out that one of the slots had failed. So the problem was the slot, not the RAM stick. You might check for that. If you have already, my apologies, I did not read through all the responses. Just a thought...
