Intel Pentium III 600E FC-PGA overclocking guide

Thresh & gang hebben een PIII-600 FC-PGA overclocking guide in elkaar geknutseld, waarin zij 3 engineering samples testen op busspeeds tot 166MHz:

After testing all three processors, we found that one was stable at 750MHz (7.5 x 100MHz), and the other two were stable at 700MHz (7 x 100MHz). The 700MHz processors simply couldn't POST at higher speeds, and attempts at 750MHz allowed us to become very familiar with the motherboard's CMOS reset jumper. Adjusting the voltages didn't help, and we decided to run a couple other tests.

We decided to test the 750MHz CPU with the 4.5 multiplier to simulate a 600EB. The system couldn't handle the 166MHz FSB speed necessary for 750MHz (4.5 x 166MHz). Our PC-100 Hitachi SDRAM that we've had running as high as 150MHz couldn't handle 166MHz. Just to make sure the system failure wasn't the fault of the AGP card, we yanked out our GeForce and replaced it with a PCI TNT2 card (ASUS PCI-3800), and the results were the same.

"and attempts at 750MHz allowed us to become very familiar with the motherboard's CMOS reset jumper"

Wat ben ik blij met mijn Asus P3B-F, als ik te ver overklok (blijf hangen in de post) ff uit en aanzetten de hele hap, en hij draait weer .

Als of jij,
After testing all three processors,

hehe right on the money W2O

hebben deze proc. geen vaste multiply meer ?
hoe kunnen ze dat zomaar weizigen ?

Het zijn engineering samples, die hebben geen multiplier lock meer.
Deze vind je alleen niet in de winkel.......
Beetje late post trouwens
