D620 upgrade chipset?

I have a Dell d620 with a t5500 core 2 duo chipset. I want to upgrade it. What is the fastest chipset that I can put into my system? I was thinking about putting a t7500 into it. seems to be way less cost than the t7600. But can I go higher than those? Can I even put the t7500 into my laptop? I already have 4 gigs of ram and a better hard drive with 16mb cache.

Thanks

 

No, you can only put 667 FSB Core 2 Duo in your D620. It is either a 945GM (GMA 950 graphics) or the 945PM (Quadro graphics).

You can put in any 2.5" 9.5mm SATA HDD in your laptop, and you can put 4 GB of RAM but the chipset can actually only see about 3.5 GB of RAM.

The fastest Core 2 Duo for D620 is a T7600 @ 2.33 GHz, but not really worth it. My T5600 @ 1.86 GHz runs XP smoothly..

 

If you plan on keeping the laptop around for longer, I would recommend getting an Intel T7200 if the CPU is really being a bottleneck. However, I doubt the CPU is that bad of a bottleneck, and would recommend reinstalling your OS first. Your D620 is capable of handling Vista or Windows 7 without issue already.

 

Flash the Bios before sticking in any upgrades, I have seen the early D620 bios do some strange stuff with 4GB ram installed.

 

Hrm mine didn't have the latest BIOS, 4 GB went into my D620 no problems.

 

I think the one that did some weird stuff was an old A02 version. It cleared up when I took it to A10.

I just looked at the updates, and A05 freed up more memory when 4GB was installed. and A08 changed some critical things.

I just know that this D620 would image fine with one of the 2GB sticks in it, but put both in and it would lock and do goofy things with both in it. I flashed the bios and put the 4GB back in it, re-imaged it and it was fine. Used to be my work laptop before I went to a D630 and then a E4300.
