Question on RAM in 4 slots.?

There were 2 dies one of the company's 2GB with a frequency of 800. In the computer 4 slot 2 colors. Stood the old 2 in one color. Now I bought the same at 2GB, with a frequency of 800, the company is different but popular. Previously, the system showed 4GB RAM, now 8, but blunt was weird. (Bioshock infinite included for 15-17 minutes, when the usual 1-2 minutes). No dancing with a tambourine in the BIOS did not. What is the trouble and how fixed?

I can assume that these two "set" have different timings, even as an option - different number of chips on the straps, or the performance - unilateral/bilateral (can affect the poll rate of the memory banks).
One way out - either through the BIOS to set the timings (if possible...), or replace all memory on a bracket from the same manufacturer (which IMHO is preferable to do a "salad" on the motherboard, it is, sir, a sign of a "bad" tone or inclinations in the direction of poverty)... Different colors of the connectors indicate that the memory modules on this motherboard can run in channel mode!

PySy: Try to run pairs from the same Manufacturer separately, sequentially on both pairs of memory sockets on the motherboard! It cannot be excluded that the variant fails some of the slats or memory connector on the motherboard... Also it would be nice to run MemTest-Ohm! If the test scores go to the store until the memory is out of warranty.!
+1 for memtest, but after that not necessarily at once to the store. Better check strap separately, see the manual for the motherboard on the placement/rotation modules and look at update BIOS. - Lucas commented on July 9th 19 at 13:11
Thank you for Your reply, accepted and understood. The problem was in other - in addition to the RAM I also bought a cooler for 120w and put it on the graphics card. Then the video card malfunctioned (code 43). The registry cleaned up, the wood was demolished, the new put - in bundle graphics driver, audio driver and so on - all of Zapak NVIDIA, but for some reason it fails in all respects. Installation error or failure, even though the compatibility check passes. (if the graphics card is not inserted or is damaged in the compatibility check, it throws an error.) Do not prompt, in what may be a salt problem? - Weston_Greenho commented on July 9th 19 at 13:14

Read the documentation on your mother. It is often necessary to put the twin module into well-defined slots.
Thanks for Your answer :) please read my comment above - Lucas commented on July 9th 19 at 13:13

And you hour not Intel with ддр2? If Yes, then their controllers are finicky. Different number and volume of cans, a row or double row strap, different tiiming - all this often leads to bugs or even failure to work normally

different colors - most likely these are two different DDR. read the documentation of the motherboard
