Windows 7 ram 8gb vs 4gb

And with that reserved memory, does that mean Windows and its drivers now runs faster since Windows took this memory for itself as some kind of "dedicated" memory?

Try only 4GB at a time; make sure you choose the correct slots such as 1 and 3 or 2 and 4 see manual. I doubt it but I had to ask.

If so, you probably have six slots and would use a 3x2GB setup. Comment Post Cancel. The most likely scenario is that you're reading the wrong information and that you do have all 8GB available. The exception is for professionals editing massive picture or video files. There's ZERO performance difference in games. Now here's the whole story: -Previously, there was 4gb "reserved".

Then someone told me to swap both new RAM sticks, i did it, and it seemed to work, Windows detecting the full 8gb without any RAM reserved.

But then later, i was getting BSODs, crashes, instability, Windows unable to boot properly, video card not able to load its drivers, sound card not able to play sound and later wouldn't play thru my speakers only SPDIF was available. May need to change the boot order.

No bootable disc can cause a black screen with cursor flashing 6 If you have errors, you need to RMA note, only 1 stick might be bad or two out of four.

It's a pain to return two sticks if that's all you have, but if you purchased as a pair they're returned that way. You can: reinstall Windows, or restore a known working backup. You'll need to reinstall. There IS a big booting speed difference now! I didn't run the Memtest in question, i took both RAM sticks out and put them back in their original G. Skill plastic package. However, the need for 16GB of memory remains a hotly debated subject, so today we are going see if and where this much memory might be useful for desktop users.

Application Performance After spending a few hours going through several popular applications and workloads, it was difficult to find any commonly used program that required 4GB or more system memory on its own. Once you have 'enough' memory for all your applications to run, having more memory won't increase performance any further.

And in this case, what that means is that for regular desktop work, you'll be hard pressed to find any tangible performance difference between 8GB and 16GB of system memory. Among the programs that we tested, Adobe Premier CC proved to be very demanding as showcased below:. Our custom workload features a 17 minute video made up of dozens of small clips, images and audio tracks.

To maximize system memory usage we turned the bitrate right down and this saw a total system memory usage of 12GB when encoding. With 16GB of memory installed the workload took seconds. Surprisingly, with just 8GB of RAM the encoding time wasn't greatly impacted, now taking seconds. Moving on to 7-Zip That said, if you are compressing a number of files that measure in the gigabytes then a much higher dictionary size would be preferred.

Larger dictionaries often make the process slower and require more system memory but result in a smaller file better compression. Doubling the dictionary size to 64MB requires 3. For our test we went with a MB dictionary size which overwhelmed the system memory as it requires 24GB of available system memory, the system then has to rely on the Windows Pagefile to pick up the slack.

The more data that needs to be loaded onto the SSD the slower the system becomes. Looking at the kilobytes per second data we see that the 8GB configuration is 11x slower than the 16GB configuration.

While having 16GB of memory is a real advantage here, we had to create an extreme and unlikely scenario.
