Which processor for my Dell studio 1555?

    I currently have a Core 2 Duo T8300 2.4 GHz 3mb CPU in my Studio 1555 and fancy an upgrade.

    Was going to go for the T9900 (3.06 GHz, 6mb cache), but have noticed that I could get a Core 2 Quad mobile on ebay for not a lot more. Some of these have 12mb cache :eek:

    I am old enough to remember hard disks with smaller capacities than that. I could run two copies of Windows 3.1 from the on-die cache, now that really is progress :D

    The only fly in the ointment is that the TDP rating is higher on the quads - 44w versus 35w for the Duo's. So the question I'm asking myself is - will my laptop be able to cope with the extra heat? :confused:

    Any thoughts?

    What chipset do you have? If it's PM/GM965, then you can't use 1066MHz FSB CPUs (including quad cores). If you have the PM/GM45, you can do a dual core, but most likely quad core will not be supported (due to lack of support via BIOS). What do you use your notebook for that requires a better processor?

    I think the Studio 1555 has the GM45 chipset.

    I definitely agree that there will be compatibility issues with a Quad.

    The heatsink might not properly cover the two large cores anyway. On Ebay the Q9000 is going for a lot cheaper than the T9900. If it could fit under the heatsink, then I would go for it. Undervolting the Q9000 will lower its power consumption. Also the QX9300 falls under the same 45w TDP category, and we know that is going to use a lot more power than the Q9000, so when undervolted, the Q9000 is sure to fit in the 35w design "limits" that your laptop must be rated for.

    Thanks for the replies, chaps.

    Yeah, this has the PM45 chipset. Shame about the quads not working properly, eh?

    As for what I do with my laptop, I play games, go on the net, that sort of thing... I guess the T9900 is where it's at then, if I want the best that will work without problems?

    You don't need a better processor for most games or surfing... what games do you play? Do you edit videos?

    Bejewelled 2 Deluxe is my favourite game at the moment. Like a bit of half-life as well at times.

    I don't really have any performance issues, it's alreay a pretty fast laptop but I'm greedy and fancy a bit more punch :D

    The t9900 isn't going to work either, the x9000 is the end of the line for your chipset and since overclocking probably isn't BIOS supported not much of an upgrade. Is 400mhz worth the upgrade?

    Are you sure the T9900 won't work? The studio 1555 is for sale on ebay with that exact processor...

    Is that a refreshed 1555? Usually 800mhz processors are not interchangeable with 1066mhz models.

    It will placebo. Your laptop won't run faster because the CPU is not the bottleneck.

    If you buy a fast SSD like the Intel you will notice it.

    Yea much past 2.0Ghz, there really is not a noticeable difference in gaming, surfing, or anything; editing and converting and some work programs will eat up the extra CPU power but that's about it.

    Says the man with an i7 ;) lol

    Well I might just go and get a processor upgrade AND an SSD. I know for sure that the laptop can take 1066mhz effective FSB processors (PM45 chipset) and Dell even sell them with processors with that FSB as an option.

    So, what should I look for in an SSD?

    Thanks everyone :D

    Haha wait til I have my after-market cooler, things will get insane.:)

    I would honestly stick to Intel right now for SSDs, I dont really follow them too much, but they are the best performing, and have decent storage sizes. They are expensive per GB, but it will be the single most effective upgrade made to your system.

    Yeah Intel is the way to go for SSDs if you have the money.

    If you're on a budget some indilinx SSDs can offer more value for money.

    The Studio 1555 does not suck. Care to explain your opinion?

    The Studio 1555 has the PM/GM45 chipset, which can accept 800 and 1066MHz FSB processors, including the T9900. However, if you already have a T8300 at 2.4GHz, that's plenty.

    Quad cores will NOT work, not because of chipset/socket incompatibility (the Core 2 Quads are indeed Socket P and have an FSB of 1066MHz), but the fact that Dell does not offer quad-core processors with this model, and so the BIOS does not recognize them.

    So, get a T9900 if you really think you need to, and it will work just fine. I would just save the money and spend it on something more worthwhile, though. For the price of a T9900 processor, you can easily buy a nice netbook or a PS3 or something.

    Thanks for the comments :)

    How do I give reps on here?

    I already have a couple of laptops that I take out on the road and don't have a desktop at all. So the 1555 will be the laptop that gets spoilt, the one I want to make the best it can be.
