Can use 8GB RAM together with 4GB RAM?

 Indeed, it's for the most part conceivable to utilize a 8GB Slam module along with a 4GB Smash module in a similar PC, yet there are a few significant contemplations to remember:

1. **Compatibility:**

   Guarantee that the Smash modules are viable with your PC's motherboard. They ought to have a similar sort (e.g., DDR3 or DDR4), speed (e.g., 2400MHz), and in a perfect world, similar timings. Blending various sorts or velocities of Smash might work, however it could prompt steadiness issues.

2. **Operating Framework Limitations:**

   Some 32-bit working frameworks have restrictions on the aggregate sum of Smash they can address. On the off chance that you're utilizing a 32-digit rendition of a working framework, it may not perceive or utilize the entirety of the introduced Smash. Most present day frameworks, be that as it may, utilize 64-digit working frameworks, which can uphold bigger measures of Smash.

3. **Dual Channel versus Single Channel:**

   Assuming you're introducing two Slam modules, check whether your motherboard upholds double channel memory. For ideal execution, it's frequently prescribed to introduce indistinguishable Slam modules two by two to empower double channel mode. Be that as it may, assuming you have a solitary channel motherboard, it is by and large fine to blend various limits.

4. **System Performance:**

   Blending different Smash limits won't hurt your PC, however remember that the framework will work at the speed of the more slow Slam module. For your situation, the 8GB Smash and 4GB Slam modules will probably work in single-channel mode, and the absolute framework memory will be the amount of the two limits (12GB). This is a compromise among limit and likely execution.

5. **Stability Testing:**

   Subsequent to introducing the blended Slam modules, it's smart to run steadiness tests, like MemTest86 or other analytic devices, to guarantee that the framework is steady and there are no issues with the blended Smash arrangement.

In synopsis, while it's feasible to utilize a 8GB Smash module with a 4GB Slam module, it's critical to guarantee similarity, know about potential execution suggestions, and perform steadiness testing to confirm that the framework chugs along as expected.
