Sweet Old P3-450s

[Vegito]

Man, I got a lot of these 450s, SL35Ds, 100 FSB 512K Cache, old Katmai core..
so I decided to strip the OEM Dell no fan heatsink and this thing posted at 124Mhz..

It ran hot as hell, so I try to get 133 out of her, and the good old BX6R2 would post with error..

I had some old micro pc100 memory and stuff, so I decided to put a stick of my crucial PC133 in and it posted and ran at 133, 600Mhz out of a 450. Pretty good for a old core.. I threw a vantec cooler on it also.. since it works at 133Mhz... another sweet processor to the cracking racks.

Cool wounder if I could do that with my P3 450 and asus p2b-ls. What voltage is it running on?

Mine runs at 620Mhz with 2.0v using PC133 Micron Cas 2 RAM

Ran happily for many months with Hitachi PC100 RAM at 600Mhz but now seems to only want to run at 558Mhz (124FSB)

I got this CPU from a mate who had it post with the 150Mhz FSB on a P3B-F

Does RAM degrade?

Im pretty sure mine would work at that speed but my ram cant take it :|

I had it at 2.3v with the pc100 ram thinking it was the cpu that wouldn't cut it.. so I took a stick of crucial pc133 and plug it in, to my suprise, they ran at 2.0v at 133FSB...

So I got everything PCI (V3 3000) in there so no problems with AGP 2/3 problems...

Keep finding all these 133Mhz able processors... I remember a while back, people said that these weren't good overclockers.... I got another 7-8 of these guys...


I sold one today on e8ay for 75 bucks.. which isn't bad, new 450 on pricewatch is like 98 bucks..

I just tried running it using the 143FSB (on my BX6 2.0) it posts ok but then I get a windows protection error. Thats 643Mhz - however it is displayed as a 600B same as the 133FSB setting when booting?
Maybe thats due to the Hitachi PC100 and Micron PC133 RAM not working together?
I'll try it again with the Micron RAM only later.....

I still have my best PIII 450 ever. It's an SL37C retail with 4.5ns SEC cache chips. It does 675 at 2.2v and 630 at default voltage.

 

[bonkers325]

they are suppose to do 600

How do you tell the cache ? My has -36 at end, assuming thats 3.6ns ? or 360Mhz maxxed, dunno, dont remember, my old sl2w8 has -45 or -5 i think, and that was 4.5 or 5ns cache...
