Hi,

I tried AIDA64 cache and mem benchmark on my new Zenbook 14 Flip OLED with a 5900HX and 16 gigs of LPDDR4X RAM at 4266MT/s and got this:

Not particularly amazing speeds. The problem is that I found a (ukrainian?) reviewer who wrote a review[1] on the same laptop but with an i7 1165G7 and posted his AIDA64 results:

Hugely higher speeds.
Is this normal? or is it an AIDA64 problem?
Or did ASUS decide to equip the ryzen variant with mediocre RAM but not the intel variant? :kookoo:

The higher setup shows quad channel and your shows dual channel. Not sure if that is the reason but could be because of that.

But the 1165G7 doesn't support quad channel:
It does show that but in ZenTimings it also shows that my RAM is running at 8320Mhz which is impossible without "quad channel" even though neither CPUs support that.

Then could be a bug in AIDA64 its happen before. Some 3rd party RGB apps can can double the actual read, write and copy. All speculation from my side though.
Try to find reviews from other sources than that one.

Here is an example of high AIDA64 numbers caused by RGB software

Makes sense. It would be downright scammy if they used such wildly different chips for the same model with intel.

Although the laptop has (thankfully) no RGB, it does have MyAsus app (with lots of crap functionalities) bundled with it so maybe that causes the 8320Mhz reading for me. I looked up notebookcheck's review of the same model with a 5800H and the AIDA results are similar to mine.

The sub 50ns AIDA benches coming from you and the others kinda spoiled me ngl :rolleyes: ButI guess that's the laptop life.
