Clocking an AMD 2800 Barton

Hello, im new here and i could do with a good computer forum to ask about some problems as Im not on any so i think i'll set up camp here.

Anyway, i've got an Asus A7V8X-X series motherboard and a AMD 2800 Barton processor running on it.
I've got 512mb DDR333 installed.

Right i found this site here which tells you all about what you should set the multiplier to and stuff.

Well i set everything up as its telling me there.

Multiplier = 12.5
CPU external Frequency = 166/33
vCore = 1.65v

Well when i set the External Frequency to 166/33 it keeps warning me to set it lower as the memory frequency needs to be at least 333 or greater.
Even when i set the memory frequency to 333 I'm still getting the same warning. If i just ignore it and save and exit, it wont load into windows. It just crashes and keeps restarting the computer.
The only way I can get rid of it is by setting the CPU external frequency to 133 but then the CPU is underclocked at 1.7GHz. This is a 2.GHz CPU!!!
Can anybody tell me an alternative Frequency setting and multiplier to use?

not sure about that cpu but the idea is to keep your FSB frequency and dram frequency as close as you can the same, 1:1 ratio.. for me i have to use a divder of 4/5 to get good over clocks. just keep changing your ratio, and and underclock your cpu so that it ensure you will boot. if it doesnt boot try a different divider setting, and lower FSB if you have too. just get it to boot first.

download CPUZ and see how your HTT mhz compare to your memory..

i have a a64 venice and HTT is at about 280mhz ram is near 230mhz
 
also once u get it to boot with a good divider slowly go up in 5mhz increments, run memtest and supper pi (32m) test if it passes both you can go up more mhz..
 
yes............................lol sorry but i dunno how to do that.

I can only get it at 1.7GHz and 2GHz but i'd rather not underclock it

I've got that CPU-Z now but what is this Super Pi? Is it used as a speed test and benchmarking system?
Are there any programs that I can use to set clock the cpu within windows?

If your memory is rated below PC2700 then you need to set the memory clock separately (or use the lowest common speed between them)

You can try 133x15.5


Noting that you do have PC2700 class memory, consider bumping the Vdimm of Vcore or both (depending on what is giving you the problem)

why not underclock, its not like its in stone you just restart, hit delete and start over clocking. the point is to get your pc to boot to see how stable it is, you did say your having boot problems. if nothing I said made much sence, you should do some more reading and research and will find a lot of answers to your own questions..

It calculates pi to (up to) 32 million digits, which is very processor extensive.

Unfortunately (if i recall correctly) you can set the amount of memory you allocate for it and thus you only test your CPU directly (rather than say, PiFast which allows you to test RAM as well)
