[QUOTE=Antonio;438181]MSI GP62 laptop, after upgrade...[/QUOTE]

You'll probably get some interesting tests by comparing things like "1 thread on 4 physical CPUs" and also you may as well disable testing on hyperthreaded cores entirely (like 8 threads on 4 physical CPUs). No matter what the benchmarks show, it won't help and will only slow things down.

Going from single to dual/triple/quad channel is a pretty nice performance bump in real world testing, but some of the benchmarks you had, like "1 thread on one CPU" don't reflect that.

Single channel basically made it a dual core cpu performance wise. Dual channel doubled the performance. More memory speed would still increase performance. For 8192K the single core ms/4 = 9.5 ms/iter while 4 core was 11.6 ms/iter.

My son's new PC Intel Core i7-6700 @ 3.40GHz ... multi-worker slowdown...
 

Intel Core i7-6700 @ 3.40GHz Windows64, Prime95, v28.9, build 2
12 GB of RAM.....trying to find out the specs of it and in how many sticks.

Looking at 2048K for example the increase from 1 core alone to 4 cores concurrent is more than double. This is way more than I expected or have seen in my experience.
Anyone else have similar experiences with this CHIP?

Interesting that fastest timing for 2048k versus 4096k slows down less than factor 2.

I have a laptop, with a10-7300, Bulldozer, "4" core, 1.9 GHz, 3.2 GHz advertised turbo. Single channel ddr3 1600, 4GB.

(these "measurements" are done by running 1 w 4 thread - LLD 2400K FFT)
If i have turbocore on, in full load, HWMonitor show the clockspeed jumping from 1500 MHz to 1800 MHz. [After i wrote this, found out turbocore depends on TDP headrooms. But HWMonitor displays just under 27 W (cpu+igpu), and the "power cable" has 65 W output written on. So i don't know why it's throttling.]
If it's running idle ("empty"), it shows the freq is hovering about 2700 MHz (and sometimes up to 3200MHz), rarely 2400. Also in idle, the Voltage is higher than under load. (1.0250 V vs 0.8875/0.8250 V)
But if i turn turbocore off (by AMD OverDrive), the clockspeed stays around 1900 MHZ, and delivers *slightly* better performance (in prime95). Also i can safely low the voltage by 2 hundreth of a Volt (0.9250->0.9062). ALso while turbo off and under load, it's still having a ~27 W power, no throttling, 1900MHz stay.

turbo ON:

Plus it may be placebo, but in the "Worker Windows", if CPU affinity is set to "run on any CPU", seem to have better times than "CPU #1". For 4 multithreads.

Indeed.

[QUOTE=Xyzzy;438452]It sounds like an 8GB and 4GB stick. Maybe it is not in dual-channel mode due to mismatched banks?[/QUOTE]

To clarify does that mean that both sticks are on the same side of the memory bank instead of 1 on each side?
