There’re two Low Latency Interrups related items, Low Latency Interrupts (LLI) and Low Latency Interrupt Ports (LLIP). By default LLI is disabled. Select Port-based. Then go on to LLI ports, add port 48168 or whatever desired. I’ve sent you clearer photos.

Marcin, you should update your guide according to the new driver for the JCAT Femto net cards owners.

Are there any new options?

There're two new parameters that seem interrelated, SR-IOV and Virtual Machine Queues. They default as Enabled. Recently I've changed to Disabled and like it there.

Hi ThuanB,

 

I recently got a pair of these cards, though still building my Audio PC so only using single PC right now

 

Strange thing adding this card into the single PC has benefited the SQ significantly which surprises me very much. -Using bubble controller for Femto.

 

I have disabled SR-IOV and Virtual Machine Queues and certain this has benefitted SQ too

 

These are amazing cards

 

Thanks

John

Hi Guys

 

My Net Femto card is not showing up in windows server.

 

I have tried everything I can think of that is obvious - new riser cable, checked power, reinstalled drivers - I am getting nothing.

 

I don't believe its the card, it must be something else - can anyone help me with ideas to try, things to check and look for?

 

Thanks very much

How do you power it? If you don't see it - should be a power problem.

From a Jcat 400w linear - I will try a different psu to rule that out, the linear is brand new and powering the mobo and cpu just fine

I'd temporarily replace it with a different card, generic or whatnot. At the same time, put the Femto card onto a different port or a different computer to see if it works there.

Take it out of the server, boot to Windows, power off and then reinstall the card.

There is a chance that the card failed along with your previous PSU. To confirm, please install the card in a different PC.

Marcin

Hi,

 

for my part I get even better SQ since I'm using a Teddy Pardo 2x5V - 3A Linear PSU to feed the 2 JCAT Net Cards FEMTO installed on my Control and Audio PCs..  :)

Tell me about it. I did a step further, upgrading the stock fuse to Furutech, and love TeddyPardo even more

Concerning fuse replacement I've yet successfully replaced the fuses of my amplifier and my DAC by SYNERGISTIC RESEARCH -  BLUE fuses.

Next step will be certainly the fuses replacement on my 2 HDPLEX 400W ATX full linear PSUs for my control PC and my Audio PC and on the Teddy pardo.  ;)

Where do you find these options?
