Great Upgrade for IBM T42 Thinkpad
While not the same as a Cure 2 Duo, this 2.0GHz CPU gave me some breathing room on my THinkPad T42 that had a 1.7GHz CPU. The CPU isn't running at 100% most of the time anymore, closer to 65-70%, other than running anti-virus or anti-malware scans, as these consumes resources.
Able to watch YouTube videos more w/out being so choppy, though not 100% perfect, a noticeable improvement. For $10 shipped from a reputable eBay seller (this part is important), the CPU is a fantastic deal. There is another that runs at 2.1GHz, though for $15 more, cannot justify the cost for only 0.1GHz more power.
This item will be further appreciated by those running lesser powered CPU's than I was, some are in the 1.2-1.4Ghz range, these folks will get the most out of this CPU.
A final word & caution, don';t get these confused with the models beginning with '7' & ending in '0', these won't work on many computers that has a model that has a CPU that starts with a '7' & '5', it's the 7 & 5 models that's needed due to the FSB. On the other hand, those who has a CPU beginning with 7 & ending with 0 will see a negative performance, as the CPU will clock down below the rated specs (again, has to do with the FSB), so don't cheat yourself out of performance id running say a Dothan 760 to a 755.
Lastly, use a good thermal paste to do the job of keeping the CPU cool, after cleaning the CPU & Heatsink with 91% alcohol. Arctic Silver 5 is the best around, use only a very tiny amount, spread it with a old credit (or similar) card & it should be just a glaze, reinstall the CPU & tighten in a criss cross pattern, not tightening all the way at first, use 4-5 rounds, then a final snug.
Once installed, make sure that the computer is running good, then download the latest version of Prime95, let it run for no less than 12 hours (the Arctic Silver 5 needs this to cure), and preferably 24 if possible, make sure the main battery is removed to prevent overcharging (constant topoff charging) that'll eat away at lifespan. This will provide a good curing of the paste, although it takes a total of 200 hours to finally cure, the rest can be performed by normal usage of the computer. Do not cheap out on thermal paste, while I use & recommend Arctic Silver 5 (also known as AC5), MX-4 is also good, what I was using before AC5, and takes less cure time, though higher temps, which many of these notebooks with this CPU is bad at, running hot. Quality paste will prevent this.
Am 100% satisfied with the Intel Pentium M 755 that I purchased, met my needs perfectly.
