cpu or bios?

[cjpp78]

Few questions.. I have a acer aspire 5552-3691. Most stuff I've read says it has AMD m880g but CPU z says AMD 785gx. Don't know what to believe plus can't find any official info from AMD on a 785gx only 785g. Any info?

Second thing.. I have tried to update CPU on this laptop. It has a athlon II 340p and I tried to upgrade to phenom II n660. The computer wouldn't boot up with n660 , nothing at all but power light and fan. Replaced it with original p340 and computer starts as normal. I have latest bios for the board. Would a different bios be needed for it to work or is it most likely the CPU is no good?

This review of the Aspire 5552-3691 on CNET says the chipset is AMD M880G.

The Details tab on this cached spec page for another Aspire 5552 (AS5552-7677) spec's the same chipeset. It uses an AMD Phenom II X4 N970 2.2GHz. See this page on cpu-world.com for more info, including the family of chips that includes this model. That will tell you more about which chips will probably work in your machine.

Typically, the second set of four digits in a part number like that refer to varients of the model with a different combo of CPU, RAM, HD, etc., on the same basic motherboard and case.

If you can find the drivers for your machine, the titles may tell you what chipset they are for, or you can look for the inf and/or readme files in a zipped, downloadable driver package.

Good luck.

Update - I found a PDF from Wallmart with the specs for your exact model. It defintely uses the AMD M880G chipset.

Thanks for all the replies and helpful info. Unless I'm missing something I thought the phenom n660 was compatible. Same core family ( champlain), same socket s1g4 ). It is 35 watt vs 25watt of p340

At the bottom of the page on cpu-world.com, it says the thermal design power is 35 watts. Under that, you'll find a listing of specs and the relative performance of similar, related models from P920 - P960. p920, P940 and P960 are 25 watt designs, if that's what you want, but the other model I linked on Newegg uses a P970.

I was looking on cpu-world and when i searched my stock cpu (p340) i got the list of similar cpu choices. the phenom n660 was on the list but not highlighted like the rest..oh well I think ill give the phenom n970 a try. similar performance with mullti threaded performance being a lot better. thanks for the help

You're welcome.

If I'm right about the similarities of the models, the P970 should work as well for you as it did for Acer.

Well I broke down and contacted Acer support. According to them the phenom n660 is compatible with my computer. This leaves me scratching my head..
