FSB/Cpu/Motherboard issue?

[MrIceCremeLollipop]

OK, So Im trying to get a PC up and running, It has a Pentium e5400, 3GB ram, 250gb storage, running on an Asus P5LD2-VM. So it runs,Got windows 7 installed ect. But there's 1 problem that seems to consist even when trying windows 10, 7 and xp, Which makes it horribly slow. In the bios it says the CPU is running at 1.35 GHz, In the properties of windows 7, 10 and xp it says "Pentium e5400 2.7ghz 1.35ghz" 

 

I initially thought the FSB was too slow, (CPU requires 800) But then I looked at the specs for the motherboard and it said it supported 1066/800/533 MHz, What confused me more is that it was running at 900mhz, With the otpion to change it greyed out. 

 

I know The wordings a bit weird, But please excuse me Im quite confused at this.

maybe you need to scroll a bit lower to see the option? Otherwise, try find the bus speed (not fsb) and set that higher (default should be 200). Also, the multiplier should be 13.5.

Nope. Nothing To do with Bus speed, Nothing can really be changed to do with clock speeds.

These 945 boards running 2 Pentiums, lol, a pentium 4 chipset, so max 1066 for core 2,but you run a newer Pentium D on it, E6400 is a Core 2, you mixed them up, you get max 800 on these newer E6400 Pentiums, budget release next to the budget X 9550, mean for intel 4 chipsets, not the 945 or 965! Budget CPU's next to the i7 lineup, to compete with Athlon.

those CPU don't always run on full tilt. On normal desktop use they throttle down,

 

You could run a tool like cpu - z or speccy, then take a look at the cpu frequency on idle, then start something more demanding and keep the frequency in view. It will go up then.

Like @LucasRem, I also suspect the chipset support problem. Socket 775 is a weird one. Old mobos don't support newer CPUs running at their full speed, but you can still fit them in and run slowly.

Not a clue what you mean lol.

Jurrunio, it gets supported, only on 800 FSB max, not on 1600 or 1066 as Core 2 CPU's can do.

 

PC building is not that hard, stay in the right era! not mixing up Pentium 4 and Pentium D CPU's They are compatible, that 775 socket was good, but when you mix gens, it's getting weirder and weirder....
