Does anybody know, what VRM components are used on the ASUS WS Z390 Pro (https://www.asus.com/us/Commercial-S...WS-Z390-PRO/)? I couldn't find anything on google and ASUS support isn't helping out (they say it's board level confidential *lol*). I couldn't find any pictures without the heatsinks or of the backside, so I can't figure out the VRM on my own.
I'm interested in buying a ASUS WS Z390 Pro. But with all that Maximus XI twin-8 stuff going on, i'm a little hesistant on going with ASUS this time.
I would appreciate if you could share any thoughts about that board. I'm looking for a Z390 board with PLX chip, so there is only the supermicro and this one, but supermicro is nearly impossible to get in my country. Are there any pros / cons you would care to point out about the WS Z390 Pro?
At the YT time index in your link he's talking about a plx chip, as well. So the WS Z390 Pro (for which I'm asking about VRM details) is exactly that: the intel platform which Asus did the same thing for. 😉
Depends on how you look at it. Its 16 PCIe lanes multiplexed to three PCIEx4-NMVEs (12 lanes total) plus a graphics card with potentially 16 lanes. Of course the bandwidth at any given time is still limited to 16 lanes. But as I'm not doing any GPU-bandwidth intensive tasks, the GPU will use up that 16 lanes only rarely and only for a very short period (if at all). So if you look at it time-multiplexed, there is definitely (except for very few and short exceptions) full bandwidth available for the NMVEs.
As for saturating those SSDs, I have a very unusual use case. One component is high IO intensive database access, so its more about the max IOs at high queue depth than about max sequential data transfer. And I have other components accessing the NVMEs, which I can't have competing with each other for SSD access, thats why I'm not using RAID but seperate SSDs. And with that scenario, it's even more important to have the SSDs on direct CPU attached lanes.
HiVizMan said, he is trying to get a few details while I'm still wating for my CPU to get shipped. If even he can't get any details in time, I will probably have to buy the board to check out the VRM and hope for the best.
