PC Processors

I have been testing 2990wx and 2950x for last couple of weeks and I have some questions:

• I have noticed that Ryzen Master 1.3 does not work if virtualizaion is turned on, is this normal/expected behaviour?
• I also noticed that for some of my loads, machine runs faster when I have Ryzen Master running (why? what does it do that BIOS can not do it on its own); interestingly, cinebench runs slower, in my workloads difference is roughly 10% of performance - I have done this testing at least 20 times for 10minute workload each and I can repeat that easily

I also have some "arhitectural" questions;

• in avaliable presentation of 2990wx, it appears that there is one infinity fabric link between each die, and if I read correctly bandwidth of a single link is about 25gb/s?
• in 2950, two active dies are connected with two IF links so bandwith between the dies in 2950 is double of what we have in 2990wx (50gb/s)? is this correct?
• numa blocks 0 and 2 are dies connected to the ram, numa blocks 1 and 3 are one without direct RAM access?

p.s. my current setup is msi meg creation (bios v1.1), 2990wx, 32gb ram g-skill 3200, samsung evo nvme 1tb disk, PBO is activated with all default settings, win10ent

I have also faced this type of problem previously. then I get some useful suggestions from mobile repair Dubai . I refer you for this site but it surely helps you to solve your problem. they give quality services.

mrakar, I cannot answer most of your questions but suggest you contact AMD directly via an Online Support Request, this is a user forum and most here do not work for AMD (I don't).  Your Ryzen Master is DL (1.4+ is available), but for some reason it does not run if SVM is Enabled.  Here is an image of the paths in the 2990WX:

Notice the dark areas on the upper right and lower left chips.  These have no connection to memory and data takes a double hope and no direct connection to PCIe.  Not much help.  Enjoy, John.
