Hi Guys,

I have been running a Pentium III Katmai at 550Mhz on my 440BX MS-6156 mobo. I originally ran a Pentium II at 400Mhz.

According to the datasheet here for the SC1152CS regarding Vcore, it says the max ampage is 15A for load regulation - https://pdf1.alldatasheet.com/datasheet-pdf/v … H/SC1152CS.html

But according to this page here - https://www.pchardwarelinks.com/elec_pentium.htm - the max load for this specific CPU is 17A.

Windows, benchmarks have been fine, but a couple of times I have had a no-signal on boot, but when removing all drives, CPU socket, GPU and putting them back in, it works fine, but this maybe due to a loose IDE to SATA converter as it;s a tight fit, so may just be a coincidence, but on a whole am I doing any long-term damage running the Pentium III, too much load on the SC1152CS, or reducing its lifespan.

Many thanks.

I think that 15A means the max load under which they measured the sample circuit. It would be more relevant to check the max current the MOSFETs in the circuit can carry.

Agree, the mosfets are what handle the current, not the controller, the CEB703AL has a max of 40 amps.

Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun
