all my a64 s754 are DTR's (help)

i had bought 10pcs of OEM procs from a supplier abroad for our
planned wi-fi servers. however, the plan was shelved as the procs
arrived so they lay rotting in their trays long forgotten..

now, i had this itch to upgrade my rig at home and so i bought in a mobo
(asrock k8n upgrade)...to my surprise, all procs are DTR (but they have
heatspreaders with ADA3000 part nos., but CPU-Z says otherwise..

what reflected on CPU-Z and mobo once started:

AMD Engineering Sample
Clawhammer
L2 cache - 1mb
speed - 800mhz
F48 SH7-CO stepping

vcore - 1.26V

now, can i adjust multiplier beyond 4x? it seemed locked at 4x)..

and why are they identified as Engineering Samples? am planning
to return this to the supplier, is this much better than what i bought
or was i rigged? it cost me $125 each including shipping

thanks! or is there any bios for asrock k8n upgrade that can work with
this procs? i've tried the latest and its still fixed at 4x...

AMD engineering sample?!?

Try installing AMD's processor driver to see whether Windows can switch it back up from where BIOS left it. You might be out of luck because typically, those drivers rely on BIOS provided tables.
