Cool Gear PCI to PCI Expansion

Post by fraz »

Hi,

Just been looking at one of these expansion boxes - Please see below

https://www.coolgear.com/product/pci-ex ... ansion-box

Is there any technical impediment or reason why this would not work with 3 X PCI cards onto a PCI-e slot?

After reading the tech specs it shows 2.5 Gb/s (Giga-bits-per-second)

USB 2 = 480 Mb/s (mega-bits-per-second) which is good for 24 channels I/O simultaneously

480 X 4 = 1,920 mega-bits-per-second or 1.9 Gb/s - Giga-bits-per-second so - Which is enough bandwidth for 96 channels I/O

The reason why I write this is that a 3 Scope PCI system would not have as many I/O channels simultaneously and should work no problem with this expansion box - But I ask here to see if anyone can offer any reason why this would not work? - Thanks - :)

Try & report back, perhaps they have a good return policy.

Hello - :) - This isn't a good comment - :lol: - But don't worry - I did figure I'd try this out - and it has plenty of bandwidth 2.5 Gb/s.

Star Tech do a big box version as well but it has 2 X PCI & 2 X PCI-e - X1 - So this box will fit in two PCI cards - Two Scope Pro's 28-30 DSP - So I'll try this version out.

A little while back I got an RME card - PCI-e X1 - model was AIO - Long story short is it didn't load the drivers when the card was in the X1 slot - But when I moved to an X16 slot - The drivers loaded and RME was up and running - This was my first experience of RME - But it did revolve around a PCI-e X1 slot - and an X16 slot.

This Star Tech box is the same idea - a PCI-e X1 card that may have a better chance in an X16 slot - If it does work it means any boards from X79 to X99 to Z390 / Z490 / Z590 & X570 & C602 / C612 / C621 & TRX40 - Would be a go-er for the PCI cards - If it can work - :lol:

Often cards are X1 for logical connections, but still require the amperage (watts) supplied by an X4 slot. I have video capture devices that are similar.

Also, I suggested to try because it's doubtful anyone has yet tried it and it might be advantageous to the community. Hope that's ok!

Hello - Yes I will try one out at some point - I've bought it and now its arrived - It is STAR TECH https://www.startech.com/en-gb/cards-ad ... pex2pcie4l

Which is 2 X PCI & 2 X PCI-E - But it was cheaper to buy

The Cool Gear version looks very much the same but is 4 X PCI

No driver is required and native support is mentioned from within Windows so I see no reason why it should not work - But the elctrical connection you mention from an X4 slot or higher will be used.

Total bandwidth is 2,500 mega-bits-per-second or 2.5 Gb/s - giga-bits-per-second - So there is more than enough bandwidth

I checked the user manual which stipulates to power the unit on 1ST - Before main PC is booted - In time I'll try this out - But I can't try it now as I'm too busy looking at other things - But I've got a unit -

That looks very promising.

Initially I was a bit sceptic, cos "it's not just about throughput'. But I was also a bit lazy, so a quick search turned up this superuser.com post on PCI max throughput:

Conventional PCI buses operate with the following bandwidths:
  • PCI 32-bit, 33 MHz: 1067 Mbit/s or 133.33 MB/s
  • PCI 32-bit, 66 MHz: 266 MB/s
  • ...


I remember taking my cards on the road in a magma chassis, maybe 15y ago, on PCMCIA expansion card. For some more details, here's on old z post on them.

In theory this PCIe-to-PCI expansion box should have plenty more bandwidth, indeed.
Looking forward to reading your experience!

For 3 hot running Scope cards, this Coolgear case might need a fan.
Enough space in the back for a 80mm NB Noiseblocker or such ?
How to power the fan ?
The ext. PSU might not provide enough power for additions.
Warranty is lost when modding the case.

Otherwise it might work when it really provides enough power for 3 5V PCI cards.

IIRC, Pulsar-2 needs ~ 11W and a Scope Power Pulsar or >Pro ~ 14W.
I downloaded flyer and owners manual but don´t see any specs (Watts or VA / ampere) for the 12V AC/DC PSU.
