You're looking to optimize your dual PC for gaming and streaming. Combining the RAM could lead to a bottleneck, especially if you use the higher-end GSKILL Aegis 3200mhz modules with the lower-speed ADATA units. The result might be limited performance in demanding tasks.
In extreme scenarios, instability can arise from timing mismatches. Adjusting the RAM clock to a lower setting (like 2400 or 2666) might fix the issue, though results are uncertain.
In the worst situation, things might get damaged while putting them together. Likely, it will all function properly and you shouldn't have any issues.
