Question Asus P5P43TD CPU upgrade but doesn't POST

[Couch_Potato123]

Hi, recently I upgraded an intel core 2 quad q6600 SLACR to an intel core 2 quad q9550 SLB8V on this motherboard. It was working fine with the q6600 but when I placed the new cpu, the motherboard won't load into bios and doesn't turn on. I did upgrade the BIOS and tried to reset CMOS, nothing worked. I know the cpu is on the supported list so I have no clue where could have gone wrong. I also used another old cpu which was celeron e3400 and it worked, just not the quad q9550.
I know it's an old board already, found out that I had this equipment at home so I thought of reutilizing it.
Could anyone help a newbie? Thanks!

Specs:
Motherboard : Asus P5P43TD
CPU: Intel Core 2 Quad Q9550 SLB8V
Ram: 4x 4GB DDR3 1600Mhz
GPU: GTX 750 TI
PSU: 550W
Storage: SSD 512GB

What are the chances, I bought cpu twice, and both times they were not working. One xeon E5450 and one Q9550.

I never got anything useless like processors
There isn't fake , I don't know there is

maybe ram incompatibility
new cpus: 1333MHz
old one running: 1066MHz

BIOS is on version 0511?
use jumper to reset BiOS

Im just overclocing the q6600 for now c,:

It is the most you can do haha. Just got some RAM off of ebay, I gotta probably pay taxes up to 10 euros 😭. Hope they make an exception for 2 God forsaken euros

Was doing this out of fun anyway, because i happen to have the old hardware laying around so I wanted to build a spare "gaming" pc .

Yeah. I am doing this too lol. But my GPU is bad (a GT 730 infact lol)

Who knows, at the end of the day it is all from China, we don't know what were getting. Bats or Snakes, nah, Xeons 😉

Welp, I have tried all that, bios is on version 0511 aswell. Also did CMOS reset by removing the battery for a long time. I dont know what else there is to do. My ram is supposedly a 1600 mhz but it should run with the speed that is needed.

If the ram ran with 2 older cpus it should run with the new one right?

the bios i gave you is mod 0511, try it, you have nothing to lose

Yeah I did already, but the xeon doesn't work on this board too for some reason. The same as the q9550

the RAM frequency does not matter, it will take and play from the smallest one, the voltage must be the same

Ill try that again tomorrow with q9550 and ill give a update abt it

put the 9550 you have

 

[triplex1]

[Couch_Potato123]

put the 9550 you have

what memories do you use in the slots?

what memories do you use in the slots?

Could be incompatible memory. I think he can start with 0 mem sticks then restart and place 1 stick then Retry.

I don't know what is doing LuKaWin10 , I know these motherboards with ddr3 were capricious with some memories and didn't cooperate

True, we may not know the cause.

Sorry i only saw the messages now. I use ddr3 1600mhz memory 4x4gb , they are recognized by the system when i use Q6600.
