What operating system are you using?
win10 64 bit. Problem solved, ram in wrong slots.
However its slower on 6 x 16 mb ram than 4 x 16. Is that due to one set being not accessed as a pair?
Yes, like the dual channel configurations, quad channel configurations are similar in that the same memory channels should be used, the manual should have more information on acceptable memory configurations.
Why no one from AMD comment this?
I just got my new PC with threadripper 1950x on board and got x2 slower results in comparison with my HP laptop with i7-6500U (sic!!!!)
I bought it for data science multi thread calculation (R with doParallel and in-house .net multi thread app) but unfortunately it does not work as expected.
Could someone explain what should I do to make CPU works as expected?
Thanks in advance.
In addition, passmark CPU test shows 23k+ on my PC, not 13K.
