Works like a dream. - I bought this little devil for my ASUS K52F-BBR5 laptop. I was hesitant that my motherboard would not be able handle it but I was mistaken. I upgraded the CPU(from a P6100) and the RAM(8gb from 3gb) at the same time. Initial startup was longer than expected but everything is running perfectly! I updated my BIOS to the latest version to make sure it was prepared. This fits in a 988A socket for the Intel HM55 Express chipset. My motherboard states its a 989 socket so there was a tad bit of confusion but I did extensive research before purchasing. It also arrived a week early! Kudos for that surprise. I originally upgraded to try to fix a overheating processor issue I've been having. Unfortunately upgrading did not fix the issue. I used Artic MX-4 thermal compound hoping to help. I'm still running a tad hot but the processor seems to run cooler at idle but jumps up rapidly while performing any tasks. Review: Exactly what I was looking for for an older laptop - The CPU looked brand new and was packaged well. The seller included a wrist grounding strap and thermal compound which is a bonus. I used the CPU to upgrade an older Acer 5742-7645 that previously had a i3-370 processor installed in it that I keep as a backup and for testing purposes. Performance of the laptop increased by about 25% with this processor installed. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00PU0723I | | Best Sellers Rank | #2,620 in Computer CPU Processors | | Brand | Intel | | CPU Manufacturer | Intel | | CPU Model | Core i7 | | CPU Socket | BGA1288, PGA988 | | CPU Speed | 2.8 GHz | | Cache Memory Installed Size | 4 MB | | Customer Reviews | 4.6 out of 5 stars 25 Reviews | | Manufacturer | Intel | | Mfr Part Number | SLBTN | | Model Number | Core i7-640M Mobile | | Platform | Android | | Processor Brand | Intel | | Processor Core Count | 2 | | Processor Count | 2 | | Processor Series | Core i7 | | Processor Socket | BGA1288, PGA988 | | Processor Speed | 2.8 GHz | | Secondary Cache | 4 MB | | UPC | 789398904625 | | Wattage | 35 watts | ## Product Details - **Brand:** Intel - **CPU Manufacturer:** Intel - **CPU Model:** Core i7 - **CPU Socket:** BGA1288, PGA988 - **CPU Speed:** 2.8 GHz ## Images ![Intel Core i7-640M SLBTN 2.8GHz 4MB Dual-core Mobile CPU Processor Socket G1 988-pin - Image 1](https://m.media-amazon.com/images/I/51vHuMr50wL.jpg) ## Questions & Answers **Q: Will this work with a gateway nv59c?** A: I don't know. You should contact gateway support at http://us.gateway.com/gw/en/US/content/support-overview. The chip socket may be the same but the BIOS and/or motherboard may not support it. For example if have integrated graphics on your chip or not that will impact the usability of this one as a replacement. In the end just reach out to gateway and they should be able to tell you if the model chip is compatible with your hardware and firmware. **Q: Cant you ship to Turkey?** A: I'm very sorry, only ship to United States **Q: Will this work in dell n4010?** A: It appears that the socket type is correct for fitment but I cannot tell you if the chipset is appropriate for compatibility, also this processor would not be a significant upgrade if at all. I would suggest leaving the i5-450m you currently have. **Q: Will this work on Samsung RV511?** A: YES ## Customer Reviews ### ⭐⭐⭐⭐⭐ Awesome!
