Product reviewsIntel Core 2 Duo T7700 2.4GHz Dual-Core (LF80537GG0564M) Processor

Upgrade from Pentium D

My laptop is a Acer 4630z. It originally came with a Pentium D chip at 2 GHz. I bought this chip based on the multiplier. Seeing that most laptop bus speeds are locked. With a multiplier of 12 & front bus speed of 166 I expected to maintain the 2 Ghz speed, but nope. This chip boosted the front bus speed to 200. times that by 12 & you have 2.4 Ghz speed. I have seen heat spike over 75 degrees c. (watching Netflix) & that's hotter than I'd prefer so I'm going to look into better cooling options, Or another chip. Overall I'm very satisfied with this chip. Unlike my Dell Inspiron 2200 I did have to full dismantle my laptop to install.Read full review...

Works for a while, but then HDMI port stops working

I originally bought this device for streaming purposes, and it worked well for the first few days, albeit with not great video quality at default. After those few days, the device had stopped working, with video only showing up if you put the hdmi cable in a certain way. Not reliable.Read full review...

Notable power boost for the price.

I got a Core2Duo T7700 to replace the T5250 in my old Acer 5620.

The motherboard is the well known Columbia 48.4T301.01N and with the latest BIOS it will work with Meroms (T7x00) and Penryns (T9x00) with a FSB of up to 800MHz. So the most you can get is the T9500, but it is an expensive CPU for a computer that is a end-of-life product.

Passmark index for T5250: 831.
Passmark index for T7700: 1426.
Passmark index for T9500: 1830.

This CPU can be had for 16 euro, and is a good price to boost about double the computing power of the notebook.

Installation was simple: remove fan, remove heatsink, replace CPU, drop ArcticSilver5 thermal paste and reinstall heatsink and fan.

It works noticeable faster, after all, a T7700 is about 75% of the computing power of a Intel i3 330M. The T9500 is the same computing power of a i3 330M.

Of course the main problem with the Acer 5620 is the Vista Operating System, that can be enhanced by turning off several useless services like Superfetch, Readyboost and Windows Search.Read full review...

Great for older core2duo

This is one of the best early core to duos and is more likely to fit old laptops that are socket P. Keeps up with T8300 and only about 15% slower than T9300 costing a lot more.
If you know what you are doing a great fix for under a fiver.Read full review...

Very cheap, very simple performance enhancer.

I bought this CPU for an old Acer laptop. It works very well, and no point in going to a more expensive T9000 series. (It replaced a Celeron 550 which was horribly slow.)
Recommended upgrade for older socket p Intel boards.Read full review...

CPU performs well.

It took me 4 hours to reach the cpu socket unscrewing hundreds of screws of a Datron TW7 but it worthed the hardwork at last...

Best C2D for the money you'll spend!

Intel hit a home run with this processor. Best bang for the buck for the Merom/Penryn CPUs in my opinion. To get a larger onboard cache and/or more speed, you'll pay $100 or more. With some judicial shopping around, I found two of these for $23 each, featuring 4MB onboard cache (most tasks are completed on-die) and it operates at 2.4GHz (2.6GHz if you have Intel Dynamic Acceleration enabled in your BIOS). If you use ThrottleStop, you can even enable IDA on both cores at the same time for a really sneaky overclock! A huge bonus is the power usage - far less than the older P4D hybrid dual-core. Heck, it's less than AMD dual cores.

I bought this to upgrade a Toshiba Satellite L305 laptop, which was a bargain-priced stripper with a Celeron900 processor and 2GB of RAM, loaded with Vista Basic. Ewww. Upgraded the BIOS to the last, newest version then swapped out the Celeron for the T7700; installed 4GB of G.Skill DDR2 RAM, and changed out the 160GB hard drive for a 500GB 7200rpm unit. It now runs Win7 Home Premium without hesitation and pages load FAST. The processor alone would have been improvement enough.Read full review...
