Unhappy Why won't my T-Bred 2000+ do over 1930MHz?!

Hi, and welcome to my very second :clown: post on the AOA Forum !
I've bought a new system about a week ago and it's running fine basically, accept for one thing: My T-Bred 2000+ won't run (at all) over 1930MHz ! As you might know, the board that I have (8-RDA) is supposed to be famous for it's overclockability and it will do 200 to 210MHz FSB on my system, so that can hardly be the problem.
My exact setup is this: Q-tec 450W (I've blown up 2 300W PSU's already by running the CPU @ 2,1 V :nervous: ), EPoX 8-RDA w/ 40mm fan on NB, AMD Athlon 2000+ (labelled: AXDA2000DUT3C, RIRGA = Thoroughbred A) unlocked (L1 bridge is intact) @ 1,9V w/ Zalman GoldPlus cooler, OEM 512DDR PC2700 333MHz CL2,5 RAM @ 2,9V w/ Thermaltake passive cooling, Leadtek Winfast A280LE TDH GeForce Ti 4200 8X AGP 128MB DDR @ 280 X 590 MHz, sofar I' m able to get 13382 3DMarks @ 1024 X 768 X 32.
So, like I said my system will easily do 200 MHz FSB, but only @ 9,5 multiplier, the only way to squeeze 1930 MHz out of the bloody thing is 193 FSB x 10 MP and it won't do ANY higher.
So... I have a few questions about this issue:
- Why does my MB display "FF" in the POST screen all the time?
- Could my CPU not be as unlocked as I think it is? (it will do 3 to 12,5 MP but not 13 to 24 ))
- A MB voltage mod wouldn't be necessary I reckon (although I am prepared to do one )
- Any other suggestions?
By the way, I don't think it's a temperature problem, my CPU gets 47 degrees Celcius under full load, my RAM, NB, Mosfets, SB and GeForce always stay "touchable" too...
I really hope you guys can help me out on this one, 'cos it's really frustrating for me to read all the posts of guys doing 2,1 GHz with their 1700+ CPU's!!
Thanx in advance,
Elwin :beer:

t-bred a's arent as oc' able as the tbred-bs everyones been ocing lately. your tbred a is about at its limit. the reason they can get 2100mhz out of the 1700+'s is cuz they are tbred-bs. sell your proc on ebay and buy a tbred-b with the money

I read somehere that T-Bred "B"'s were supposed to max out at 2.00 GHZ while T-Bred "B"'s were supposed to max out a 2.25 GHz. There is also apprently some physical difference between the design of T-Bred "A" and "B".

A's and B's are different... On a typical setup with decent cooling, "A"s generally top out between 1850 and 1975.

B's generally top out between 2000 and 2500.

The differences in spread are caused by different steppings, and a little luck.

Your results are not surprising at all. They're right in line with some of the better (newer) Tbred A's.
