I have a GIGABYTE 7DX AURRORA Mother Board with an AMD T-BIRD ATHLON 1.0 GHz 200FSB 256. I upgraded the processor to an AMD ATHLON XP 2000 1.8 GHz 266MHz 256KB. When opening system from control panel the processor now reads 1.36GHZ. I was informed by the seller to modify the FSS to 133 and the multiplier to 13.5. However I can't figure out where to make these modification/changes when I am in the C MOS utility. I have been through every section that I can find, and nowhere is there an option to make the modifications. Any assistance would be greatly appreciated.
You just have to know what to look for. Each BIOS labels things a little differently. Look under Frequency/Voltage Control...
- set ClkGen Spread Spectrum to disabled
- set CPU Host/PCI Clock to 133/33If that doesn't work, you're going to have to change the DIP switch settings. Do you have the manual for your board?

The seller you mentioned should have told you to set the multiplier to 12.5 w/ a 133 cpu frequency (that's the stock setting for that chip). This would make the chip run at approximately 1667 MHz. It appears your multiplier is still set to 10. As jam suggested, look in the manual to see where you can make the appropriate adjustments.

Using the RSS reader "sage" extension for Firefox I was finally able to download the manual as the manual download page was nonexistent. The modifications have to be made on the motherboard as jam suggested. Found the page for CPU Speed Setup DIP switch settings chart. Now on to locating where to change the multiplier?

The multiplier is locked on the CPU & cannot be changed. If you attempt to change the setting, you *may* make the system unbootable. As plyduster pointed out, the correct settings for a 2000+ are 12.5 x 133MHz.

Upon closer examination of my Gigabyte 7DX motherboard, this board does not have a DIP switch. Also in the C MOS utility there isn't any ability to set ClkGen Spread Spectrum to disabled or set CPU Host/PCI Clock to 133/33. Now I am back to square one. Am I stuck with 1.36GHZ for the speed of the 1.8 HGZ processor because it is what it is?

The OP claims to have a 2000+ which you correctly pointed out is supposed to run at 1667MHz (12.5 x 133MHz). However, he seems to think it's supposed to run at 1.8GHz with a 13.5x multiplier. If that's the case, he has a 2200+ not a 2000+. I would guess that's correct because he claims it's running at 1.36GHz. 13.5 x 100MHz = 1350MHz but if his board slightly overclocks the FSB, say 100.5MHz, that would put the CPU at approx 1357 which would be recognized as 1.36GHz.
Anyhow, I did some more searching & it turns out that the Aurora-Gigabyte 7DX is a board made exclusively for MicronPC & it only supports 200MHz FSB. However, according to the following thread, if you solder the jumper, update the BIOS & press CTRL+C rather than DEL, it will take you to the BIOS options that I mentioned in response # 1. I don't know if the OP is up for all that.

Software overclocking *should* work, but the max safe CPU frequency would be 112MHz. Any higher than that & the AGP/PCI go too far out of spec.

I stand corrected. I have replaced the AMMicronPC T-BIRD ATHLON 1.0 GHz 200FSB 256 with AMD Athlon XP 2200+ 1.8GHz 266MHz 256KB Socket A CPU, and not with an XP2000 as originally stated.
