so i have this Asus p5b-mx that should in theory let me press any CPU up to ~3.2Ghz,but that's the problem because i can't even overclock my current E2140(1.6Ghz) more than 2.16Ghz(270x8) and i of course tried tweaking the setting such as ram speed(going from 667mhz to 533mhz) and increasing the voltage etc. but that doesn't get me anywhere past the 2.16Ghz dead-line.
And i am pretty sure that might be the rams fault,cause i have 2x2Gb chips but when i only had 1x1gb,1x512mb i didn't even go past 1.8Ghz and i think those ram chips where slower.
So my question is if i install a Pentium E2220(2.2Ghz) will it overclock better? or at all? will my Pc work? It is after all higher then what i can get out of the E2140 and they'r pretty much identical.

Thank You.

I think It's enough that you have overclocked to around 2.16GHz , I had an E2140 back in 09 and couldn't even cross it across 1.8GHz OC , so I suggest you have done well , you see that when CPU's are made in the Industry line , even the exact model has variable overclocking potential , for example 2 E2140's come out of industry Line and one is a 1.7GHz Processor , but Intel doesn't have a model of 1.7Ghz for it so they stamp it at 1.6GHz , the other one might be exactly 1.6GHz so they stamp that too as an E2140 , so the first model can or would overclock better , then the latter , assuming this I think you did a great overclock , It's just how CPU's are made , Intel Guys don't know what Speed will it run at until they really test it...
that is at the moment not a solution, the question remains.
i have seen people overclocking the e2140 as high as 3ghz that's a pretty good overclocker in my mind,but never mind let's just presume that it isn't so would the e2220 overclock by the same ~25% or would it even work on stock speeds? (if my ram is bottle-necking the CPU speed)
 


I think you should get a Core2Quad and skip both Pentiums entirely. Overclocking is never an exact science and if you're using the FSB method (increasing base clock) like I presume you are, you'll only manage an increase of about 300Mhz before the computer starts to BSOD.
 


I don't get the BSOD at 2.16Ghz but if i go 2.2Ghz it doesn't even give me the BIOS boot up and yeah i am using the FSB method anything else i can try?
 
As you probably know, overclocking the FSB will also overclock any other components that communicate with the CPU (so everything in other words). It's one of these components that will be the cause of the BSOD.

With that in mind, you need to decrease the speed of the other components (RAM, PCI slots, etc) to compensate for the increased FSB. If your motherboard doesn't allow you to do this in BIOS then you need to use resistor cables. I've not played around with these myself so I can't advise on the specifics, but I'd say that the end result isn't worth the effort.
 


the motherboard allows to choose ram speed between -Auto -533Mhz -667Mhz but it dsnt help changing t
hose options so i think it's the PCI preventing the system from loading and there are many options for that frequency and now it's set on Auto what number should be choosing? without the risk of cooking my PCI slots..
 
It's impossible to say, you'll need to try various speeds until the computer is stable. The easiest way is to work out a ratio; for every increase in base clock, you decrease the speed of the other components by so much. Once you know what that is, making further changes will be much easier.
 

tried reducing it to a minimum 90 PCI but it still doesn't go from 270X8 to 280X8 the CPU just doesn't want to go above 2.16Ghz no matter what doesn't even POST

I suggest you get the Intel Core 2 Quad for that Socket (I am assuming it's LGA 775? Correct me If I am wrong).
The C2Q will overclock better and is really cheap nowadays , plus you will enjoy way better performance than the Dual Core Pentiums you got there.
Best of Luck.
