unfortunatelly you have dead or undervolted memory. try to go into the BIOS and see how much voltage does the ram get. it should be arround 2.1. also as you have 4 sticks, try to downclock it a bit - probably down to 900Mhz. you wont see much difference in performance, but should sort your problems
ok i am assuming you have two sticks, 2GB each, yes?
It's possible the memory could be bad, the timings look ok, but I would need to know more about the memory, type and specs.
Try this because if any one of the sticks is seated wrongly, or somehow shifted it could bring up errors.
1.) First shut down pc and unplug it, then press the power button to discharge any excess power in MB.
2.) Then remove the ram and then put it back making sure it is seated well.
3.) Power back up pc and run memtest, check the results.
Should you have any errors again with both sticks in place, I would repeat step 1. and remove one stick of ram and then reboot, checking the single stick with memtest.
(then repeat, exchanging the stick for the one you previously removed)
This is to determine which stick is bad if any.
This is the only way to check each individual stick.
Should any one of the sticks show errors individually, you will need to exchange the pair for a good set.
If the PC is in warranty, Vadim will exchange; they are usually very good about this.

if you still wish to test your memory, the method I shared should still be done, but do not mix up you pairs of memory, as you test each stick individually.
Make sure you keep the pairs together / seperated from the other pair as you test individually.
slot 1 & 3 are a pair
slot 2 & 4 are a pair
Have fun and enjoy the process, this is what owning a Vadim is all about. Having Fun. Even when it means getting your hands dirty under the hood.
