Rosewill 2-Port PCIe Serial Card

Pros: Works without drivers on Win7 x64. Full and half height bracket.

Cons: none for my use

Overall Review: Bought this for a glucose meter to log reading to a computer. Plugged it in to a Win 7 box, Windows automatically found a driver and it worked. For my use its perfect.

Fast card

Pros: 1. Easy to install
2. Fast
3. Low profile
4. Black circuit board and grey fittings, very modern looking

Cons: None

Overall Review: I use this for a plotter and my data transfer rates have increased 10 fold coming from the stock USB plug. It also has a much more reliable connection than USB. I don't seem to drop jobs quite as much as I used to so, this card has been one of the best productivity choices for my business. Would definitely buy again and have, for my spare unit.

works great.

Pros: I bought this for a friend who owns a retail shop. He had equipment that had to use RS-232 and the new computer did not have it.

Cons: None.

Overall Review: He has been using this card in a retail shop that does a fair amount of business for a few years now. Not one bit of trouble.

AVOID

Pros: None

Cons: Causes Win7 x64 to lock up constantly (within 10 minutes of boot). As soon as driver is uninstalled, computer runs great. I've tried the driver on the CD, the driver on the website, and the driver from the chipset manufacturer and none of these solve the problem.

Manufacturer Response:
Dear Valued Customer,
Will this still happen if you install the card on a clean installation of Windows? There may be a software conflict in your current installation. We haven't seen many of the issues that you are describing since this product was launched in 2008. It may just come down to a software conflict in your current installation of Windows. If you are still having issues after that, please contact the Rosewill support team either via phone at 800-575-9885 or via email at techsupport@rosewill.com.
Thanks,
Rosewill Customer Care

DO NOT INSTALL 2 IN CERTAIN MOTHERBOARDS

Pros: Provides extra serial ports.

Cons: Two of these cards destroyed TWO Intel DQ45CB motherboards!

One out two cards ordered did not work in one motherboard, but worked in a different computer. Returned/exchanged for RMA. 2nd one arrived and installed then killed my first motherboard. Received another motherboard not knowing what had happened. Took it slow in swapping out the MB, and it worked without these cards installed. At the point of installing both of these cards, the computer would not POST or boot anymore again! Removed the cards and the computer was still dead. Something about having 2 cards installed killed the MB, or the 2nd RMA'd card was bad.

In between my first motherboard and 2nd, I tried both these in a Dell Dimension 4700, and they worked. So I'm not sure who to blame, the RC-301EU or the Intel DQ45CB. But I do know 1 out 2 of these cards was faulty.

Overall Review: I ended up using just the 4 port RC-305E card which I did not see before ordering 2 of these.
