Based on the diagram, the 16 processor pcie lanes can be divided for different uses (like NVMe). But that motherboard uses all 16 for the x16 pcie slot. So, everything runs through the chipset. That was the point I was trying to make.
Basically, everything you will be using is sharing the...
Also, it looks like that motherboard has a full electrical 1x16 slot. So that means any NVMe drive that you might be using is going to be connected thru the chipset.
Ahh... That was just a one of their examples screenshots, not my system. The "one row" comment threw me off. Just wanted to make sure we were talking about the same thing.
Here's a generic block diagram for the Z490 chipset.
All USB ports are attached to the Chipset. None directly...
Weird. Never seen one like this. Maybe an Intel xhci side effect. Not sure I trust the details, but it says one controller which would imply shared bandwidth. Very hard to believe they are all on the same controller...
In that case, try USBTreeView from https://www.uwe-sieber.de/usbtreeview_e.html
It should show you a tree with your different ports. You may have to move a device to different ports to see whats attached to what.
You may want to research your hardware further. Bandwidth for non-processor attached USB ports will likely be shared at the hub / chipset level. At the processor level, I'm not sure. They are probably independent, but you would have to check the processor specification to be sure. At the...
Great. I hope it works out for you.
My experience with USB is that there is still a certain amount of issues that cause devices to disconnect at times or take other measures to resolve. I experience 1 or 2 per month with various devices. It's a personal preference / bias on my part. If it...
Guilty as charged. The group today had been re-labled... Somebody in Texas did not get theirs. :)
I actually figured that some or all would get canceled. That's my typical experience with CDW B-Stock. All of these were still sealed in the original packaging.
Yeah, I was hoping to see some...
Yeah, 11 yesterday and 5 today. First 256GB is running memtest in a X10SRA-F right now. The X10SRA-F has little to no memory control, so they are not even being pushed. Just a burn in test.
Memory IC's are virtually unmarked. No branding on the ICs. Only IC marking is 10-1706-33-BA-XE...
Yeah, I'd be surprised if the onboard m.2 were at issue. Manual states:
"The U.2_1 slot shares bandwidth with M.2_2, U.2_2 slot shares bandwidth
with M.2_3. When M.2_2 slot is being populated, U.2_1 slot will be disabled.
When M.2_3 slot is being populated, U.2_2 slot will be disabled."...
They are there. They can be incredibly small. I've never seen an adapter cable without one (even if they are within the injection molded plastic). SATA and USB use different signaling protocols and are not directly compatible. USB-C does have alternate signalling support in the...
Indeed. It does not even look like the M.2 card would fit with nothing plugged in.
What you are trying to do via USB is going to add more points of failure regardless (i.e. USB <-> SATA converter will be required for each drive).
Given the concerns with points of failure... I think your best...
Hard to tell from the pictures, but would these work with that M.2.
How much vertical space to you have between the top of the M.2 SATA and your heatsink? These are very short and have a super flat cable.
I've used both when building in tight setups.
