Windows 7: Gigabit ethernet card not faster than built in

Gigabit ethernet card not faster than built in

I have a pentium 4 pc that had built in ethernet on the mobo, i replaced it with a gigabit ethernet.

I did a speed test at speak easy with the built in and got 60ish mb. I disabled that device and used the gigabit and i got 38mb with or without jumbo frames 7k.

Something is obviously wrong?

I performed the test 4 times with similar results. I have updated both cards with the latest drivers via win update.

Pretty much doesn't matter what you use for an ethernet card as you can never get a faster connection that what your ISP will allow. As for the speed differences between the two, what is your connection speed from your ISP supposed too be?

i dont think any of that is the matters. the simple issue is, the gigabit is half as slow as the 10/100 card. so something is obviously wrong

I only use one at the present time (on occasion it's been beneficial to have one spare to use to set up another device), but I have rather a lot of video files I want to copy to my Home Server...

gigabit ethernet speed questions, do you get 3/4 or 1/2 or full speeds
Is a gigabit connection a pure connection at a gigabit OR does the connection adjust speeds lower or higher or what? If you look into the connection data and see no errors and your connected at a gigabit rating does this mean that is a real gigabit or has it negotiated some other speed rating.

I'm out of ideas. Tried several different drivers, and settings. Using a fresh install of Windows 7 RC. The drivers all seem to "work", by which I mean Windows 7 has no problem with them, but no driver I've tried will let the card actually talk with anything. It keeps trying to find a DHCP...
