Unlocked Duron, noise, and the power

[monotone]

Got a KT7-RAID, Duron 650, and FOP-32 up and running at 900 (1.8v). When i wanted to crosh the L1 bridges i foound them already crossed? It might be a old cpu i got, can anyone tell me how to determine what week it's manufactured?

Here are the marking on the cpu:

- Malaysia
- D650AST1B
- ACAA0021BPFW
- 91583151366
- (c) 1999 AMD

and on the lower left: 26822

The noise of the FOP is immense, i turned over the fan to suck instead of blow since i heard that's better. My 235w psu i holding up quite nicelly, to my surprise.

It's quite nice going from this: (celeron@450)

Dhrystone ALU: 1218
Whetstone FPU: 604
MMX: 1793
FPU: 645

To this: (Duron@900)

Dhrystone ALU: 2524
Whetstone FPU: 1215
MMX: 5030
FPU: 6139

0021 = 21st week of 2000

reversing the fan works best with a skirt, (simular to some Alpha's), where the skirt forces the air to enter around the base of the heat sink, where the HSF is the hottest,

without a skirt, your better off with a blowing fan, and adding a case fan to evacuate hot air out of the case

Thats one old Duron. Week 23 is about the earliest that I have seen. As posted, if you don't have a skirt, its best that the fan blows instead of sucking.

My psu died It was working just fine, i turned off the computer to get something to eat, turned it on about an hour later and nothing. I had to wait till today to buy a new one (aopen 300w). About the same price of a aopen midi-case!

The cpu must be from around may or something. Maybe they gave me this one because i also ordered kt7-raid & fop-32, and they knew i would be overclocking.

Did what you suggested and turn the fan over again. It only runs at about 4300 rpm, is this normal? When it was sucking air it ran at about 4600 rpm.
