[arsse]

Hello.
Please Help.
I have bought Dell Inspiron 15 3576 i3-7020U and bought 2*8GB DDR4-2400(19200) RAM Crucial Part naumber (CT8G4SFS824A.M8FD) and install in this Dell laptop.

I had had Lenovo G500 with pentium 2020m +2*8GB DDR3-1600

after testing i see newer laptop with DDR4-2400 result is poor than DDR3-1600!!!!!!!!!!!!!!!!!!!!!!!

why?!!

In that sequence of CPU-Z screen shots above, why does the center one show 598Mhz as the RAM frequency?

Thanks for helping me.
When performance test or any other software not work it show 598Mhz NB and dram 665 but after start RAM testing, it show NB=1994 and dram=1197.

I saw this link:
https://www.memorybenchmark.net/ram....D+8GB&id=12318

Average RAM Mark is 2783
Samples: 9
but my RAM is 1784 !?

I want to know what is this problem!
Is there any baseline for Dell inspiron 3576-i3-7020u for see what was ram result for this kind laptop?

Your CPU, Core i3-7020U, will probably be below the average mark listed on the site. Per the Graph Notes,

CPU dependency

If you are using a slow or old CPU, then it is unlikely to push the RAM to its performance limits. In these cases you can use any compatible RAM without being greatly concerned about its speed. The major bottleneck is likely to be the CPU and not the RAM. For the charts we have only included results from the fastest AMD & Intel CPUs. Including results from slow CPUs would mean we are measuring CPU performance not the performance of the RAM.

If there were any submitted, you can try the Manage Baselines feature within PerformanceTest to see if there are comparable systems in our database.
