1.8 Dual-Core without Pins on Bottom

Last response: in CPUs
Share

I just obtained a non-functioning computer that I'm trying to refurbish for my son to use. It's an Acer 5640 that has a 1.8 dual-core and 3gb of ram. It booted up but to a blank screen. I will now skip all the troubles-shooting I've done and get to my question. I pulled the processor to verify its specs and noticed that its flat on the bottom with the pins remaining on the mobo. Is this correct? I was going to replace the motherboard but I'm used to the processor having the pins on the bottom. I'd hate to get a different motherboard from Newegg only to find it was flat and the reason the pins were on the original Acer mobo is because it was a hybrid configuration. Does this even make sense? If you have any input, I'd appreciate you sharing. I have noted the replacement mobos that others in this forum have migrated to but most are now obsolete, so if anybody has any recommendations, I'd appreciate them.

Well Intel went LGA with socket 775 and beyond. The CPU's just have contact surfaces that touch the pins on the mainboard socket. What is the make/model of the board? That could help someone here determine what you may be able to replace it with.

That is probably the E4300 Intel Core 2 Duo or the E6300 core 2 duo the E6300 is 1.86GHZ the 4300 is just 1.80ghz eithier way you will be fine getting any mico ATX lga 775 board I found this cheap Gigabyte board that will fit in that case.

Now you will run in to a little problem with the power button switch and lights but its not that big of a deal since the case is proprietary the connector for the panel is not universal. You can however just place the connector onto the new board in a way so that the power button will function or you can rewire the front panel all together.

Now before you do this I would make sure you know for certain its the motherboard Iwould test the RAM and PSU before you do anything also reset the Cmos battery. If there are multiple dimms in use 1 at a time to see if it will boot.

Sounds great. I kept reading it might be a core 2 duo as well (which is what I was hoping to find when I pulled it) but the chip is labeled with the following... Intel E2160, Pentium Dual-Core SLABZ Malay, 1.8ghz/1m/800/06, Q80A224. Does that sound funny to you?

Nope that sounds rite its basically the same processor as the duo I think the only difference is the Pentium E2160 has 1 MB of cache and the duo E4300 has 2M. It will still be a half decent processor for fumbling around the internet and stuff like. You will be able to overclock it a little in a new board and with a decent cooler you should be able to get 2.5ghz out of it and maybe even more.
