Possbile to revive a atmega328p

Hi, I have three atmega328p chips. One of them shows up fine in avrdude

C:\Users\user1>avrdude -c usbasp -p m328p

avrdude: warning: cannot set sck period. please check for usbasp firmware update
.
avrdude: AVR device initialized and ready to accept instructions

Reading | ################################################## | 100% 0.03s

avrdude: Device signature = 0x1e950f

avrdude: safemode: Fuses OK

avrdude done.  Thank you.

But the other two say

C:\Users\kushu>avrdude -c usbasp -p m328p

avrdude: warning: cannot set sck period. please check for usbasp firmware update
.
avrdude: error: programm enable: target doesn't answer. 1
avrdude: initialization failed, rc=-1
         Double check connections and try again, or use -F to override
         this check.

I was trying to write bootloader to all of them so I was trying all kinds of things. Any way to revive them or they are dead?

Do you have a crystal + capacitors or resonator connected to the "dead" processors?

I have the same problem with an Atmega328p that has a Duemilanove bootloader.
The same error shows up whenever I try to program the chip using USBasp as programmer. I tried to program it by connecting a 16MHz crystal and also by without connecting a crystal. In both cases I got the same error (as shown by jat421).

I checked all the connections and I'm sure the wiring is correct as I was able to program another Atmega328p(with UNO bootloader) just by replacing the first Atmega328p.

does you usbasp has a switch/jumper which allows you to use a slow SCK ? if it does try setting your usbasp for slow sck and give it another try i get that error using this programmer if the micro its new (never been programmed) but using slow sck i can burn the fuses/hex and after that i can use the programmer at full speed

The USBasp has a jumper which allows to use slow SCK.
I did tried to program the Atmega328 by setting the jumper for slow sck, but I got the same error.

You can reset the chip with a High Voltage programmer. I downloaded a simple design from the web and have since restored several chips.
