Hi guys ! I am tryign to figure out what my old baby can handle. According to my research it can go up to T9500, but can you do me afavior and double check me. I am a little bit confused about socket cause AIDA almost saying that my board can accept 478 and 479 but CPUID telling diff. story ...here is what I have:

P.S.

According to my research FSB of T5800 is only 800mhz, any idea why CPUID showing like I have 1330Mhz ? Anyhow basically I am looking to get best CPU for my socket.

Laptop is DELL Studio 1535, I do remember I had like 8 CPUs I could select from when I was ordering so I totally don't remember what is what.

Here is compare of my T5800 and T9500
http://ark.intel.com/compare/33918,35581

Look at T5800 socket intel saying it's 478, my CPUID is incorrect ?

Thanks a lot !

Your motherboard's socket is actually known as "socket P" and you shouldn't refer to them as 478/479 (which are actually package types), to avoid confusion with the elder desktop PGA478. As you are also aware, your laptop's chipset is GM965.

Your chipset will only natively accept 800MHz processors on socket P, to rephrase that: your laptop will accept any socket P processor with 800MHz FSB. By that you are limited to certain Core 2 Duo processors and cannot accept Core 2 Quads (C2Q's unfortunately start at 1066MHz FSB). If you install a 1066MHz CPU, your laptop will not boot.

You are correct that the T9500 is compatible, but they are not so as affordable as the T9300. The T9300 is almost identical to the T9500, the...

You are correct that the T9500 is compatible, but they are not so as affordable as the T9300. The T9300 is almost identical to the T9500, the only difference being the T9300 is clocked at a mere 100MHz lower; hence the T9300 is the best choice for a balance between performance and price. You should be able to accept all the following Core 2 Duo processors (higher you are on the list, the better the CPU is):

Intel Core 2 Duo
T9500
T9300
T8300
T8100
T7800
T7700
T7500
T7300
T7250
T7100
T6970
T6900
T6670
T6600
T6570
T6500
T6400
T5900
T5870
T5800
T5670
T5470
T5270

Your motherboard/chipset will also support Pentium and Celeron Dual-Core in addition to the single-core Celeron, however those would be downgrading from your existing Core 2 Duo. If you're also willing to experiment with your laptop, you maybe able to accept some 1066MHz CPU's if you physically modify your socket; which is a basic procedure allowing you to accept the otherwise non-supported 1066MHz CPU's. This is known as the BSEL Mod, and you can read more about it here. The BSEL mod will allow you to run 1066MHz CPU downclocked at 800MHz, hence you may gain better performance sticking to 800MHz CPU's anyhow.

All the best. :)

Thank you! :)

Yes that T9500 will be compatible with your laptop; it's completely your choice if you desire the T9500 and are satisfied with the price. :)

Performance wise you will get a decent boost (not too significant however unfortunately) from your existing CPU, however you may not notice the difference in daily tasks. Personally with your laptop, you may see a better gain in responsiveness from replacing a HDD to a SSD (although SSD's are not so cheap compared to HDD's).

All the best. :)

Another great answer indeed, but SSD was second to go in. Few years back I upgraded 2GB to 4GB and SSD (OCZ Vertex 1) And it really works great. I am looking some more on CPUs and something strange. According to Intel page T9500 release date was Q1, 08

http://ark.intel.com/products/33918/Intel-Core2-Duo-Processor-T9500-6M-Cache-2_60-GHz-800-MHz-FSB

And eBay T9500 CPU I see Intel, 06 on it .... got a bit confused, you sure this is it ?

Ahh, apologies for the SSD suggestion. Glad to hear you've already got one with 4GB RAM. :D

The T9500 you found on eBay (which you linked earlier) is indeed the correct processor, which is compatible with your laptop. On the photo of the processor it states it's stepping code, "SLAYX" which denotes it's the T9500 for socket P; this can be confirmed by viewing the T9500 on CPU-World, if you scroll down to "Core steppings" (on your left) you'll find the SLAYX is indeed listed beside C0. This basically confirms the SLAYX is the T9500 you desire on socket P. On CPU-World you'll find the "SLAYX" code beside a bunch of other codes; your motherboard will also accept those other variations of the T9500, such as (but not limited to) the SLAQH and Q9WW.

You're correct that this processor was released in January 2008, and to be honest I cannot guarantee I'm correct however, the "Intel '06" is most likely denoting that the T9500 is based on the Core micro-architecture. The Core micro-architecture is used in Intel's Core 2 Solo, Core 2 Duo, Core 2 Quad and Core 2 Extreme processors (in addition to certain Celeron's, Pentium's, and Xeon's); whereby the Core architecture was released in 2006. The "Intel '06" most likely is a way of identifying the processor is a Core based CPU. You can see over at Wikipedia on the Core architecture, towards the end of the first sentence it declares that the Core line of CPU's were indeed introduced in 2006.

Apologies for that much information (I suppose I got a little ahead of myself :D), but the processor you found should be compatible.

All the best. :)
