K7VMA

[dunny]

Has any one ever tried an AMD 1700XP cpu in a ecs K7VMA MB ? I was wondering if I would I fry the 1700 if I did.

That board only supports 100MHz FSB. The best socket A processor up to 1.2GHz and a Duron up to 850 MHz.

If luck has it and it works, its only going to run at around half the speed due to the FSB limit.

[dunny]

Thanks for the info. I guess I'll stick with the 1.2GHz

It should be able to take up to a Duron 1.3GHz with a 100MHz FSB, though it'll probably need a BIOS update.

[dunny]

Thanks. I'll check out the 1.3 Duron.

I think I ran a 1.4 CPU on this board, an original athlon, not the XP.
It was about 2 years ago so I might be wrong about it.

The 100MHz FSB Thunderbird Athlons at 1.4GHz are rare and pricey nowadays :( But they were big time power-sucking, heat-spewing machines.

The Prescott chips make the 1.4Ghz T-Birds look cool as a very cool thing indeed.

I came across those AMD 1.4's and they were pricey. $$$ I have a 750 Ath in it now with a SCSI HDD and it does OK for Mech Warrior 4.

I came across 3 CPU's ... all 1.2 but they had different numbers:

AMD Athlon , 1.2 GHz (AHX1200AMS3C) Processor
AMD Athlon 4 , 1.2 GHz (AHM1200AHQ3B) Processor
AMD Athlon 4 , 1.2 GHz (K71200200256SKA) Processor


Is there a difference ???

The Athlon 4 series of CPUs were made for the mobile market (I think). With the right OS and software they should be able to throttle down to lower speeds when they aren't too busy, but I could be wrong.

They're the first "mobile" models. They do have the "PowerNow!" energy saving technology, but they need OS and BIOS support for the speed switching. Bad thing is they fire up at LOWEST speed, and if BIOS doesn't handle it, they stay there.
Don't expect an (old) desktop mainboard BIOS to handle this.
