Intel Ethernet Adapter Crazy Man Tweak

cablenut · Post by **cablenut** » Sat Apr 21, 2001 1:15 am

Hey all im back again with a test file for you guys

This reg file should enable TCP/IP checksum Offloading for Intel Pro 100+ series of cards. Just merge the file and reboot and it should default to TCP/IP checksum offloading. This is Windows 2000 ONLY right now. TCP will generate a checksum on a packet on a send/recieve this takes up cpu cycles. Offloading it to the ethernet adapter will decrease cpu usage and improve performance generally. Offloading is done via the NDIS driver wrapper. This tweak might work with other Intel adapters also.

Updated with "checksum.reg" will test later and see how well it'll work with my Pro/100+ Managment Adapter.

How does the TCP/IP checksum offloading differ from the Intel version 5 software performance tuning feature, for increasing/decreasing bandwidth/CPU usage?

Check you network card. If you are not useing 2000. Some cards have settings on them to lower your cpu usage. I know mine does I have a 3com Office connect. It has all those settings.

Broadband Intel's adaptive technology and tcp/ip checksum offloading are two different things. I have my technology tuned all the way to bandwidth

Before updating with "checksum.reg" www.dslreports.com tested and reported my download speed as 3817 kbps.

After the update, the ideal would be to test with [url=http://www.dslreports.com,]www.dslreports.com,[/url] however, had no tool points; therefore I had to test with www.computer4sure = 4425.2 Kbps and www.optiview.com = 4808 kbps for a second confirmation.

It would seem that with an average score of 4616.6 Kbps it would indicate roughly a 20.9% performance increment after the update.

Keep them tweaks coming!

You might find it here

coolman · Post by **coolman** » Mon Apr 23, 2001 11:35 pm

ty Lobo but is there a patch i could not find it or how to

Lobo · Post by **Lobo** » Mon Apr 23, 2001 11:43 pm

No I don't believe there is a patch

Lobo · Post by **Lobo** » Mon Apr 23, 2001 11:47 pm

Gee I must be tired, I just saw how to, you may be able to find out here or at Cablenuts web site here

Luckily I have a win98 box here at "The lab" that I can get on tonight and figure out what to do

PS. Lobo this is a different crazy man tweak for ethernet cards

TCP/IP Checksum Offload Reg File for Intel Pro 100+ series of cards

Reg files for Windows 98 and 2000 now. Included are the two reg files and universal uninstaller for both of them. If you feel you do not want this tweak applied anymore right click on the inf file provided and go to install.

NOTE: In Windows 2000 when it deletes the entries in your network adapter advanced settings it will say "No Description" this is fine it just means that it deleted the Taskoffload option correctly. When you reapply the patch this will get rid of the "No Description". Same thing happens in 98 but in 98 there is just a blank space.

These will enable TCP/IP Checksum offloading for the following Intel cards:

Any 82557, or 8255a based chip Intel ethernet adapter. Examples:

Intel 100+ Series
Intel 100+ Management Pci adapter

Killing Angel can you post a shot of your network adapter advanced settings I just want to make sure it worked on a system other then the ones I have here.

Also once again this does not affect gaming it only offloads TCP CHECKSUMS now games which use UDP have checksums also but it does not offload UDP checksums

It works great, I also noticed lower pings on gaming, and faster web page loadings!
