Hi guys, I have this cpu that I want to install on PCCHIPS Mobo. There is no setting for 3.45 V, only 3.3v or 4V
I want also to put this sucker running @150Mhz.
What voltage settings should I select? 3.3V (former AMD DX4@100) or go wild to 4V?
Many thanks!
4V is probably a bad idea unless you're trying to go for 180MHz (this is quite difficult). The ADW chips are generally regarded as less overclockable than the ADZ parts, but I have had the exact opposite experience somehow.
Normally when motherboards have a 3.3V setting they actually deliver something closer to 3.45V, but the only way to know for sure is to use a multimeter. Since it's a PC chips board I'm sure they used really crappy VRMs and it's likely producing far above or below the recommended voltage.

Try 3.3V and if it fails then...
use 4V in conjunction with a good heatsink + thermal paste. I have used 4V for one of the ADW chips but I can't say how far down the road this may be detrimental to the hardware.
Agree, measuring the voltage provided could be a good idea.

Yah, the last letter is how AMD denote maximum case temperature, there's listings around for K6 class not sure about 5x86. Anyway, I found that some "high temp rated" CPUs ran hot in the first place, meaning it's 5 degrees higher than "normal" for max case temp, but it's running 10 degrees higher in the first place so actually sucks for overclocking. On the other hand, some of the low temp rated ones, seemed to run particularly cool, not all of them, anyway, if max temp was still something reasonable, i.e. something you'd expect a reasonably good cooler to keep it under on a hot day, then yah, those went like rockets. But whatever temp range you bought it didn't really seem to affect "the luck of the draw" with them. I had, maybe still have, a low voltage, high heat range K6-2 350, 1.9V core, 95C or something, going off memory here, you know how well that sucker would clock? Barely at all. Even giving it 2.2V it was hard to get more than 366-375 out of... BUT.. you could put it at 1.9V, rated speed, with a PASSIVE sink on top of the thing and it would run just fine even though you couldn't keep your finger on the sink.

Hi guys, thanks for the inputs... My goal is 150 MHz not more... I will give a go with 3.3v... if no luck will go for 4v... Anyone knows where to buy a skt3 HSF to clip on CPU? I don't like the glue on solution... But I have adhesive thermal compound
Are you going for 50x3? You would be more lucky with 40x4.
Go for 3,3v. It should be alright.
