I think I bought a faulty AMD 2.8 chip. No matter what I do, and I have exhausted all the possibilites, it would not work at the right clock speed. Instead it works at 100 MHz only. Tried it on two different M/Bs with the same result.Just interested in how frequent this prob is.Seems rare to me and therefore the title.
M/bs GA-7VT600 and then Asrock K7S8XE+. Both show same results when CPU Clock and Multipliers are set are correct setting, ie 166x12.5 it goes into a loop of not booting into Wins after post. Gives me the usaul options of booting normally, safe mode etc. When one option is chosen, the signal cut off and the comp starts again.
Well as it wont work in either mobo and you havnt another to try looks as if you will have to return it,it definately is what you bought?ie you have checked the codes on the cpu itself.Which should look something like this
AXDA2500KV4D 2368375201904 AQYHA0346TPMW
Which is my own 2500+ Barton yours would have 2800 on first line
