I've got a question into MSI about retrofitting an AMD NX1750 in place of my XP1800 on an MS-6340M v:5.0 since AMD states they're designed to be completely compatible with the Thoroughbred Series of XP CPU's.
According to AMD's specs, the NX1750 has a TDP of 12 watts while the XP 1800 a/b revisions (681 series) has a TDP of 51.0 watts.
According to AMD specs, this CPU is identical in L1/L2 Cache to the XP1800 with the exception of being slightly slower, 1.4 instead of 1.53 ghz and using about 1/4 the power.
Hopefully MSI will give me sufficient information to indicate whether I'm going to be able to successfully run this CPU on my existing mobo and if it's a go, I'll be testing as soon as I can get a Geode.
One noise factor I'm hoping to eliminate is the CPU fan by using the stock XP cooler but I don't know if the system will function w/o it but worth the experiement as it means only the PSU has a fan any longer and I'm quite willing to take a slight hit on overall performance for the reduced heat & noise.
