Mantiz Venus - Sep 2017 firmware with full 22xxMiB/s bandwidth (archive)
Just noticed Mymantiz_John has removed this full 22xxMiB/s bandwidth firmware from his blog. This firmware has been proving to be problematic with I/O ports as can be seen by user reports below:
- Mantis Venus - USB ports unusable
- Mantiz Venus - different SSD performance using enclosure ports versus Macbook ports?
In the first link above we see he has been reverting some users back to the previous 15xxMiB/s bandwidth firmware which statically allocates a large chunk of bandwidth for port use. This 22xxMiB/s firmware was supposed to dynamically allocate bandwidth for I/O ports as they needed it.
Some users want full eGPU bandwidth and don't care for the I/O ports.
Thankfully we have his original blog firmware post announcement archived at http://archive.is/YV69Z , snippetted below and this full-H2D firmare attached.
Mantiz Venus New firmware is released
Mymantiz_John originally announced this upcoming firmware in July-2017:
Excellent to see those tests, I think the performance hit may come if you are running a game at High FPS / low quality where the transfer speed would be more of a bottleneck.
HI, Please check the bench mark by
Current FW: H2D 15xx Mib/S
Upcoming FW: H2D 22xx Mib/s
No difference in Low Quality & High FPS.
Please enjoy those extra Ports and its convenience. ＾＿＾
we remove it because it will make confusion, all the shipment form July is using the Full H2D firmware, so we think it had been lasting for along while, so it doesn't need to be there.
Mantiz: ● ●
I’m using dynamic allocation firmware without issue on Sata and Ethernet. Sometime I got some USB-A he dusconnected but no issue with my mouse, iPhone dock and headset.
@dbuckingham , please see approx gaming FPS increases going from half-H2D to full H2D at:
@nando4 Is this the only/latest firmware I can apply for the Mantiz, or have there been any new developments? Because I'm experiencing half H2D bandwidth (well more than half - 16xx instead of 22xx) on my Venus.
@mac_editor I believe the firmware from late 2017 is the newest. I also have a .bin version saved too if needed. The FWUpdateTool requires the Intel Thunderbolt Software [126.96.36.1990]. It gets complicated when you want to switch to Thunderbolt Software Control later so make a Restore point. Once you finish flashing the firmware, go back to the non-Intel Thunderbolt Software restore.
Thank you. I’ve not been using any Thunderbolt software so far. The instructions provided by Mantiz mention disconnecting the GPU for this. Is this needed?
@mac_editor I believe Mantiz followed the steps I wrote in this FW upgrade guide. Things have changed quite a bit since [new procedure]. You can download Intel Thunderbolt Software. Make sure the Thunderbolt enclosure is connected and active then you're good to go.
