Please log in for more thread options i'm going to renew my htpc, transitioning from a Athlon-XP 3000, to a Pentium-M solution. In detail: Motherboard:AOpen i915GMm-HFS CPU: any Pentium-M rainging from 750 to 780. Here comes my troubles: The mobo says it support 479-pin CPU, but i find a lot of ebay auctions where CPU stated as 479 chip, are instead described by the intel Processor Spec finder, as 478 pin. Further details: the mobo manual says: "This socket supports uFCPGA & uFCBGA package CPU", and this gives me even more confusion. Can someone give me a clear explanation of which kind of CPU i need to buy? thanks in advance | |||||||||||||

Please log in for more thread options of the sellers know very little about what they are selling. You could buy what YOU think is a Pentium-M 760 that turns out to be a Pentium 4 560. Not that Intel's new number system didn't cause enough confusion, right? Instead, but from an actual computer component vendor (NewEgg and TigerDirect come to mind). This way you can make sure the specs listed are correct (or at least close enough to be sure). Hi all, i'm going to renew my htpc, transitioning from a Athlon-XP 3000, to a Pentium-M solution.

"478 pin Micro-FCPGA and 479 ball Micro-FCBGA packages". The socket on your motherboard has 479 holes. One hole is blocked out of the 480 maximum positions, leaving 479 holes. The pin grid array chip (FCPGA) that plugs into the socket, seems to have 478 pins, and two pins are missing in one corner. (The BGA version looks like it is intended to solder right to a PCB, and has 479 balls that match the S479 socket pattern.) http://download.intel.com/design/mobile/datashts/30526202.pdf The AOpen test report is here: ftp://ftp.aopen.com/pub/report/motherboard/nb4pm-i915gmm-hfs.pdf Q/S-spec Pentium M Processor CPUID Result QDRB Pentium M 770 2.13GHz 6D8 Pass QAPF Pentium M 760 2.00GHz 6D8 Pass QAPE Pentium M 750 1.87GHz 6D8 Pass QAPD Pentium M 740 1.73GHz 6D8 Pass QDMV Pentium M 730 1.60GHz 6D8 Pass SL7V3 Pentium M 765 2.1GHz 6D6 Pass SL7EM Pentium M 755 2.0GHz 6D6 Pass Pentium M 745 1.8GHz 6D6 by Spec Pentium M 735 1.7GHz 6D6 by Spec SL7EG Pentium M 725 1.6GHz 6D6 Pass SL7GL Pentium M 715 1.5GHz 6D6 Pass QDMU Celeron M 360 1.4GHz 6D8 Pass QDMT Celeron M 350 1.3GHz 6D8 Pass SL7V3 2.10GHz/FSB400/2MB cache 478 pins 21Watts http://processorfinder.intel.com/scripts/details.asp?sSpec=SL7V3 The Q-Spec processors in the list are Engineering Samples, as I guess retail FSB533 processors weren't available for testing. http://www.intel.com/support/processors/sb/cs-001616.htm This Newegg product is a Dothan. The listed order code is BX80536GE2000FJ Intel Pentium M 760 Dothan 533MHz FSB 2MB L2 Cache Socket 478 Retail http://www.newegg.com/Product/Product.asp?Item=N82E16819111172 Plugging the order code into processorfinder.intel.com -->
SL7SM 2.0GHz/FSB533/2MB cache 478 pins 27Watts http://processorfinder.intel.com/scripts/details.asp?sSpec=SL7SM I think as long as the product you buy lists 478 pins, everything should be OK. The Socket is "S479", but the pin grid array processors that will fit the socket seem to have 478 pins. Using either the SSpec or the Order Code, and processorfinder.intel.com , you should be able to get some info on what you are buying. I hope you cannot actually find any FCBGA 479 ball packaged processors at retail (like on Newegg), because an end user cannot solder those (easily) to a blank PCB. The list of Pentium M processors is here. Click "Go" and wait and wait. If you are on dialup, you'll be old and grey before this finishes rendering.
