Lenovo T500: Ugrading from P8600 to T9900 Pin configuration concern

So I presently have a P8600 in my T500 notebook, and am about to buy the P9900 from

http://www.sparepartswarehouse.com/HP,Laptop,Part,570434001.aspx


My concern is, when looking at each of these processors on Intels website, they both can come in either 478pin or 479pin. The vendor of the T9900 is uncertain as to which pin config the proc they're selling is, and, I can't find anything definitive on the Lenovo either. They charge a 25% restocking fee.. I'd rather NOT pay $80 to check compatibility. Does anyone have any insight or technical knowledge of the compatibility of these parts?

Thanks in advance.

 

And yes, I've checked these to try to make sense of it:

The T9900 is pin compatible with the P8600.

 

Haha. Okay.. obviously Im not asking you to "guarantee" that it'd would, but do you think that makes it a safe bet? Also, ever heard of the QX9000 working in the T500 ..? Or is the chipset in the W700 different?

 

I'm also considering upgrading to the T9900, and I was wondering whether the CPU in your link was somehow specific to HP laptops (I don't think this is the case).

 

There could be a severe heat issue.

It's not.

 

The QX9300 can be fit inside a W500 since the PM45 supports it, but most likely the BIOS wont, so it wont work.

May I ask, why you need all that power? 2.4GHz is quite fast for most tasks.

 

Actually, Im primarily decided on a T9900 - and since I can sell my P8600 for 150, and the T9900 is 325, my total cost to change will be a relatively insignificant amount of money for me. Additionally, I'm putting an SSD drive in, with which its much faster transfer rates, I'd guess would be able to provide more work to be performed per second. I've been doing some .264 video editing/converting, and am a power user (have many apps running simultaneously, and am generally an impatient person. I do NOT have the "W" series, I have a "T" series; the T500.

Thanks for the advice.

 

Well, the W500 and T500 are the same laptop except the GPU.

May I suggest you to upgrade only to SSD now, it will make a huge difference according to what I have heard. And if it simply not fast enough, then the CPU. That way you speed up your laptop first and you could save some money.

 

so its not worth 150 for a T9900? I thought the T series was faster even at the same clock rate.. let alone.. a higher.

 

Well, faster it is. But I would say if you are to get a SSD too, first give the SSD a try, and hold the buy on the T9900. The system should be a lot faster.

On regular usage the T9900 will bear little to no increased performance compared to the P8600 due to Intel SpeedStep that throttles them to save energy and/or battery since they are not being used, only when stressed you will notice a significant difference between them.

The SSD will bring more noticeable results than the T9900, not to mention that you save more battery this way, if that helps you. The SSD consumes less than the HDD, and the P8600 uses slightly less energy than the T9900 when idling, and somewhat more noticeably less when fully stressed (taking into consideration that the T9900 is rated at 37W).

 

Fair enough, but I have my settings such that when plugged in, its in high performance mode. And within Win7, it is common for my internet browser to not scroll smoothly, and even more annoyingly, when I initiate it playing a video file through WMP, the clip is sluggish for first 3 seconds, then if I rewind those 3 seconds, it plays back smoothly... follow what I mean? Currently using a 7200RPM 500GB drive. yes, I realize it could be the 3650 video card, and yes, I do have discrete graphics installed, as well as the switchable graphics turned OFF in the BIOS (which frees up 512MB ram), have 3GB RAM (Im on the 32b version of Win7). So, I was thinking the issue is the processor..

 

Are you constantly hitting on both cores 100% and keeping the percentage that high for long periods of time?

 

if u are it is a good idea to get the T9900... search on ebay and u might find a cheaper one... also getting an SSD is a good idea and some more RAM would help....

 

trumanhw, to me, your issues sound like a bad install...

Is this a clean install of Win 7? Or, is the manufacturer's 'garbage' software bogging your system down? How many processes are running when your computer is sitting there idle?

I would suggest a clean install, paying particular attention to installing only the most up-to-date drivers, and even simpler for now, try a simple defrag run to see if the issues are minimized for you.

Is the HD you have a Seagate 7200.4 by any chance?

I would consider upgrading to Win 7 x64 and 4GB of RAM (via a clean install - no cloning)- before changing CPU's or buying an SSD.

BTW, If you need to use more than 50% of the capacity of the SSD you're considering purchasing, then you may find that the performance even decreases below the level of your mechanical HD.
