[Solved] Significant lower Cinebench score after switching to Dual Channel? (Acer Nitro 5)

[freexavier]

EDIT: Turns out it was Intel Turbo Boost that was bumping up my score for my Single Channel benchmark as my fans were running at max fan speeds. Now I remember why reviews have bad taste for Intel Turbo Boost. 

 

 

For some odd reason, my scores a significantly lower with now having a secondary RAM, 2x 8GB RAM, on my laptop (Acer Nitro 5 AN515-55-50S0 (i5 10300H, 1x8GB RAM, 512 SSD, 1Tb HDD, 144Hz). I attached photos of the specs specs of my laptop bellow. From 2102 pts to 1306 isnt nothing to pass on. Mhm... Havent tried using CPU-Z to compare. Would be a hassle to reopen the laptop again to benchmark again.

I may or may not be wrong but it looks like you have different CAS timings for each stick of RAM. I would think this affects performance greatly and is always suggested to buy/use the same pair of memory sticks.

Now that would be an issue as I ordered this all the way from the US to here in the Philippines hahhahaha

 

Tho does the different timings causes an issue? Iirc the lowest RAM with the timings would downclock to a higher timing to match the higher timed second RAM?

Normally everything runs at the slowest common speeds when combining different timings or frequencies.

looks like they are running at 2933 C21, which is fine. are you sure there were no other background programms running the second time? or maybe the laptop wasn't plugged in, or it was on a different power profile?

Cinebench has never been very ram performance sensitive so it is unlikely for that in itself to be the cause. Both modules seem to support the same JEDEC speed/timings so that is also unlikely to be any problem.

 

Plug in the laptop and let the battery fully charge before testing, just to rule out any power limitations.

 

Let Windows sit idle with Task Manager open. Ensure nothing else is happening before/during the test.

 

Run something that shows CPU clocks (I like hwinfo64). Keep an eye on it while the benchmark is running. You will have to resize windows.

 

If the score hasn't got much closer to before, take out the new ram, and repeat to make sure you can still get the old score. Again check clocks while running.

 

Note you might get a small loss in score while monitoring software is running.

Now that you guys brought up the power settings. I just remembered I had my fans at Max Speed. I was gaming before I had it closed and the fans still at Max for some bit of idle time which then I benched then inserted the new RAM which then by when it restarted, the fans were on Auto. Turns out its just Turbo Boost acting up AHahaahhahahahah!

 

I was able to get the same score again! Thanks nonetheless guys. Good thing it was just some simple boosting feature.
