Well, your computer seems slower because it is lol. You lowered the cpu speed from 2.8ghz to 2.2ghz, you're going to notice a difference. You need to raise the voltage to the same has the voltage of your RAM. I can't really help you out on the specifics because I haven't had to do this yet so I would wait for a techie to respond before you change anything.

yeah, i know it would be slower.. i was just stating that.. i dont know why.. and the thing is.. that i cant manually raise the voltage..

Don't go messing around with voltages until you are sure of what you are doing. You definately do not want to raise your CPU voltage to the same level as your RAM voltage. PC3200 DDR RAM typically requires 2.6V, while anything near 2V is certain death for the CPU.
Can you give the exact specifications of your CPU? This problem probably has to do with the faster RAM effectively overclocking the CPU due to the locked FSB:RAM ratio on most motherboards. However, without knowing the FSB of your CPU, I can't be certain of this.
Also, keep in mind that while most DDR RAM requires 2.5V, your PC3200 DDR RAM probably requires 2.6V. If the RAM isn't getting enough voltage, this could cause the problem you are experiencing.

Can you get to BIOS with default settings (without downclocking the CPU) with the new RAM? If so, can you write down and report as much info about the speeds of the CPU and RAM as you can? Also see if there is any setting involving an FSB:RAM ratio, or something similar.

No, the only way i can run normal BIOS settings is if i have my old ram in and yes there is a FSB:RAM ratio

here is my mother board manual it has all the BIOS stuff in it...

But surely you are able to access the BIOS with the new RAM. (How would you be able to lower the CPU speed if you couldn't?) I need to know what the BIOS settings are set to (at default) with the new RAM. The manual can't provide this info, as people have different CPUs and RAM.
If this really isn't possible, could you give me the same info except using the old RAM? At least this way I would have the correct CPU settings.

i lowered the cpu speed with the old ram in then shut down and put new ram in... thats how i got it to work but i will not be able to reset to default and have it work and yes i will put the old ram back in and give you the info.

CPU operationg speed 1867(133)
X- CPU FSB Clock (Mhz) 133
X- Multiplier Factor 14x
- Estimated new CPU Clock 1866Mhz
X- DRAM Ratio (DRAM:PCI) By SPD
X- AGP Ratio (CPU:AGP:PCI) Auto (4:2:1)

X- CPU Core Voltage By CPU
X- DRAM Voltage 2.65

This is with my old RAM in and everything set to its default
anything else needed?

I'm not seeing where it shows the FSB:RAM ratio, but it seems to be about a 4:5 ratio. Thus, with your new RAM which has an underlying speed of 200mhz, the FSB would be running at 260mhz, which would cause your CPU to be running at 3360mhz, which it cannot handle with stock voltage.
What are the possible choices for the DRAM:PCI ratio setting?

You definately do not want to raise your CPU voltage to the same level as your RAM voltage.
I probably should have been a bit clearer. I meant to raise the RAM voltage settings to what the actual voltage of the new RAM is.
