And also My bios version is 2.6.3 .. what is the main fault in it.... kindly anyone tell me.... what should i do ???
Hi Asfand_Munib,
Before installing a new processor, please update the BIOS to latest version from Here.
Note : Please save and close all running programs and documents and disconnect all external peripherals (printer, flash drives, external hard drives, etc) and connect the computer to a surge protector before updating the bios.
If all the lights are green and you are not receiving any beep codes from the system then it means that the processor has been installed correctly. Please check if the keyboard lights (Capslock, Numlock, etc) respond when you press the corresponding keys. Please verify the connections on rear of the system and check if they are connected firmly. Also, check if you are able to hear any windows jingle sounds after some time when you power on the system. Please share the exact model of Optiplex 745 you are using as it comes in 4 form factors viz Ultra Small Form Factor (USFF), Desktop (DT), Small Form Factor (SFF), and Mini-Tower (MT). A picture is attached below.
Please reply with the information. Will take it further from there.
I think only the C2D 6000 series is compatible with the 745. Conroe only and no Wolfdale's or Yorkfields. The E5300 is a Wolfdale.
I Have Small Form Factor (SFF)
Now I Agian Istall new bios version and put processor Into board and when truned on p.c my p.c directly on and number 2Light is now showing .....
just turn on pc and let it to be on at least 1 min and notice if there is any sound of beep or window login...
Did you clean off the old thermal paste and apply new? Unless the new bio version supports it, I don't think it will work.
yep he did that... but no avail...
Most likely then is that the E5300 is not supported by the Dell bios. I have the 745 SFF and upgraded to an E6600 which worked perfectly. In my research, the E5300 was not supported. Some people look at Intel's website and conclude that the chipset supports the E5300, however, this does not matter if the Dell bios does not support it. In this case though, I don't see that the E5300 is supported on this chipset if you look HERE. Click on compatible products on the left side.
