Is a single standard run in memtest86 4.3.7 enough to be sure that all the RAM levels are safe and healthy?
If not, then tell me how to do it more effectively than to banish a standard test several times?

Addition. I bought on Aliexpress 4 levels of Chinese DDR2 800 2GB for AMD only.
My motherboard is Asus M2N32-SLI Deluxe . When I first installed 4-slats my memtest86 showed errors and hung up without completing the tests, and with different launches the number of errors was different and the hangs in different places. one 2 3 enter image description here After that, I took out everything except 1 for the slots and re-ran the test, the test was passed, added another 1, the test passed, added, another 1 test hung again, I thought it was in this bar, replaced it with the remaining one, and the test with 3 bars It was passed.
I thought that all naschel faulty bar. I took out everything except her and put it in the slot closest to the processor, and put it to the test, expecting it to show its malfunction, but the test was passed! I added 1 more to test in dual mode 128bit , the test was passed, I added the remaining 2, I already thought that I had a problem with the motherboard, but even then the test was passed! I swapped the very first bar that I thought was problematic with the next one, which was in the same channel, and put it to the test again ... The test was passed!

Can there be such a thing in general that all the slats are intact and the problem strap failed, for example, due to insufficient installation effort, but at the same time its full volume was visible and summed up with the others, or due to the special arrangement of the slats in the slots, with that they have the same chips, or the like?

He left after the first successful run, which took just over an hour, but the second run took almost 6 hours. five 6 Is this how it should be?

    "If not, then tell me how to do it more effectively than to banish the standard test several times?" - remove all strips, except one studied, and run a heavy game or stress test in a program like Sandra. Repeat for each plank. Memtest makes no guarantees, you need to test in real conditions. If the problem is only with a few installed strips - is it incompatible or there is not enough tension to work together. - MSDN.WhiteKnight

If you're interested, on the Asus M2N-SlI Deluxe (not M2N32-SLI Deluxe) motherboard, the “for AMD” Chinese memory in the 2GB DDR2-800 slats works only if you insert 2 any modules. Adding a third causes inoperability. In this case, all 4 memory bars are healthy and work as a pair in it in any combination. And in any motherboard on an AMD chipset (770/790) with the same processor (and memory controller), all four bars work successfully. This is such a strange thing, I’m generally surprised that you managed to launch 4 modules on Nvidia. Startup and performance of such memory is still strongly dependent on the processor model, the newer the processor, the more compatible it is with this memory. For example, the old Athlon 64 X2 4200+ may display blue screens with this memory, and the new Athlon II X2 250 may not have any problems.

If it is interesting, the memory "for AMD", happens, is got on Nvidia chipsets for Intel, which is also funny. But also with strange restrictions, such as only one module or something else.

    Memtest is usually left running at night, but this is in cases when the computer is buggy and there is a suspicion of memory. You have a clear problem with dual mode. The most intelligible explanation that I read about such a memory is that they use chips from the northern memory and their native frequency is 667 MHz, i.e. 800 is overclocking. From here you can give a recommendation to reduce the frequency of memory. And in BIOS load "Load Fail-Safe Defaults" timing settings. Personally, the last one helped me with such a memory, when Memtest made mistakes.

    PS A strange decision, of course, to take the memory with 2GB slats. I have two 4GB Kllisre strips, the mainland Asus m3n78-vm on the Nvidia gf8200 chipset, everything works. Not at the maximum timings, of course, and there are compatibility problems with conventional memory.

    • so, AMD's memory controller is located in the CPU, motherboard support for these or other memory boards means nothing. The main thing is to support the processor. - Sergey Pavlov
    • And how much do you think the AMD Athlon 64 x2 (Windsor 90 nm F3) supports? ru.wikipedia.org/wiki/… - Ilya Indigo
    • As far as I understand, it is useless to look at Wikipedia and specifications, this is not a documented feature. The memory controller AMD has an address bus with a bit depth increased by one bit. Therefore, AMD can be set with double memory capacity. At Intel, such memory is clear that will not work. About Athlon'y will not say anything. Checked with phenom 8650. - Sergey Pavlov
