    Hello, i want to replace my processor, but i have no idea what is compatible and what i have to look for :confused:

    My current Laptop is a Lenovo 3000 N200 - model 0769-ERG
    The processor i have is a Intel Pentium Dual-core T2390.

    I want to replace this processor because my laptop needs to be faster for the software i use for my study (i use AutoCAD, Photoshop etc. foor Architecture study).

    Is it for example possible to replace the processor with a Core2Duo P8600?

    Or is a Core2Duo T8100 also compatible?

    And wich one is better?

    Can you run CPUz and check what chipset you have?

    Is this one good? It further says that my chipset is Intel GM965?

    T8100-2.1, T8300-2.4, T9300-2.5, T9500-2.6 are the 45nm Penryns compatible with your system and are recommended CPU upgrades. Could also go a 65nm T7300-2.0 or T7500-2.2 but they run hotter.

    I have another question.

    what does L2 Cache means?

    the T2390 haves 1MB, T8100/8300 haves 3MB, and the T9300/9500 haves 6MB.

    And what is the FSB Speed? T2390 haves 533 MHz, and the other ones have 800 MHz.

    And what is nm? ( Lithography) the T2390 haves 65nm, the other ones have 45nm.

    I want to know wich processor is the best one? T2390, T8100, T8300, T9300 and T9500, and what are the differences?

    Goodbye

    T9500 is the best one. However it is only 0.1GHz faster than T9300 but a lot more expensive than that since T9500 is the top-of-the-line processor.

    I would highly recommend you to buy a T9300. You won't be able to notice the performance difference between a T9500.

    You listed them correctly in order of worst to best. I will add a few models for if you are on a budget (all still 45nm).
    Worst.... ...Best
    t6400 < t8100< t6600 < t8300 < t9300 < t9500

    L2 cache makes very little difference.

    FSB speed is in fact why you cannot use a p8600. 800mhz is your limit (p8600 is 1066mhz).

    nm (lithography) is the distance between transistors and other components on the chip. The smaller distance & lower number nm the less voltage is required to run it, therefore you will have longer battery and lower temperatures.

    This is said everywhere, unless you do a lot of CPU depending works this is true. But I'm the type which likes higher L2 cache better :D

    L2 cache is the memory that the processor uses to when it needs to pass the instructions, i.e. when it does it job. Always the higher the better.

    Some argue that there is a difference in games and so forth, but since you dont have a real gpu, you probably wont notice. What you can do to game on it is to use a VIdock, meaning a desktop gpu will power a external monitor while being connected to your pc, the difference in games from the gma965 that you have is huge, I know I had the same model that you have.

    poor thing that the screen died on me. ;(

    Most benchmarks show that "more cache" makes NO difference in real world use and gaming. The only time more cache makes a difference is rendering and synthetic benchmarks.

    oh wait rendering is just for numbers? oh boy what do we do?

    and it actually does in game, one of the causes for intel being faster is the size or in most cases the presence of the L3 cache

    My celeron t3000 with 1mb cache bsel modded & oced to 2.9ghz may not beat t9600 but will beat your t9500 at everything. End of story.

    Anyway there is no point in arguing. If the OP was trying to decide between a t6600 and a t8100 then it would be 100% worth discussion, but that doesn't seem to be happening.

    The T4400/T6400/T6600 800Mhz 45nm Penryns have been demonstrated to work on some PM965 chipset systems such as Dell Inspiron 1525 or Acer Extensa 5620z but it's not 100% guaranteed. More than likely need a updated bios with new cpu microcode. These CPUs were bundled primaryily with PM45 and GL40 'budget' systems.

    The T8100/T8300/T9300/T9500 45nm Penryns are designed to work with the Santa Rosa chipset. They have the additional SuperLFM and IDA features which the above series do not so can deliver better performance and battery life. These CPUs would be my choice for a hassle-free CPU upgrade of your system.

    Thats very interesting, I had absolutely never realized or considered they were OEM cpus.
    I have t6600 on my xps m1730 so thats another added to the list.
    Thanks for the info.

    pm965 is the same as santa rosa (you made it sound a little like they were different)

    I dont understand what is different about gl40 vs gl960 BTW but thats a different subject.

    The OP machine may not properly support the T8xxx or T9xxx CPU, it will probably chuck an error message relating to thermal sensing error.

    Hey,

    New member but I've been playing around laptops & cpus for a good while. Just dont use this website much.

    Saw your Q. I had a similar thing. a 965 chipset with an rusty processor. I would say.... Do T7700 or T7500 as your safe bet. Or if you want to go rough, Yes you can try T8 and T9. But yet you need to upgrade bios because the new Penryns are NOT SO NICE to certain motherboards and chipsets. For example, my fam has a HP. It's super hot. So... I really wanted a Penryn for upgrade... But I was too afraid that it's just going to NOT work. So I'm just going to give out a T3200 that I eBayed for $7. As I said:

    1. Penryn is hot but NEW for motherboards without new BIOS. AND... Lenovo doesn't give much BIOS upgrades.. do they? I'm a thinkpad user...

    2. Merom T7 series does run hotter..... But with effective RMClock undervolt with T7's SuperLFM.. it can drop temp back down a little... (Actually RMClock seems to work better for Meroms?) and then you get FOR SURE safety that you can purchase a T7 without messing up. I actually have a T7500. Probably going to sell soon. It can IDA to up to 2.4GHz which is norm for T7700 (and yes T7700 can IDA to 2.6Ghz)

    What is that an example of?
    You doing what you recommend to others?
    Okay.

    I think its worth the risk for 45nm and 600mhz. Youre making decisions on about a 1% probability of failure.
