using a correctly detected Pentium 2 with the L2 disabled in the bios setup I was then able to enable/disable it with setmul no problem. Think I'm simply out of luck on this one. Edit: I was able to enable the l2 cache with the PowerLeap CPU control panel CCP 5.1.0.1 Sorry if I wasted space on the …

I have a DEC 5510 PC (tower version of dec 3500) with a 440lx and PhoenixBIOS. I want to try running a Mendocino Celeron 533 in a slot adapter. It will hang on self tests where it checks the L2 cache after it identifies the CPU as a Pentium Pro 366. Disabling the L2 cache in bios skips that test and …

What I usually do is attach the positive lead of the fan to 12v and the negative lead to 5v so the fan runs with 7v. This will spin the fan fast enough to cool... usually 5v is too little.. but it cuts the speed down a lot so it's quiet. I recommend using thin wire to connect the 3 pin fan connector …

Nice find! This was the very first laptop I bought, got it at the end of high school and used it in college. Mostly to download files at school and war drive with netstumbler for open wifi, only had dial-up at home so I'd download iso images and game demos where I could. I remember running Linux …

Amazing, great job! Don't know of any specific tools for L2, sure you know of all the standard ones. Speedsys should show a graph of the cache, cachchk7 will show in txt, WinTune 2.0 looks pretty if you want to use Windows. Looking forward to seeing the results posted.

Yes, it works. Definitely no problem to run a 100fsb chip at 66fsb but a 66 at 100 could be unstable. I have a locked Pentium 133 which does 200Mhz with a 100Mhz FSB. Lots of flexibility using a super7 boards, lots of fun trying different combinations. There's also a pin mod for slot 1 boards to run …

I consider anything which runs in a SS7 board to be a 586 class, even a K6-3+ because it doesn't have cmov which prevents running i686 Linux Kernels. To me anything which runs in a socket 3 or older is a 486, socket 4 and newer would be 586 class until the slot 1/A 686 class CPUs arrive. The IBM/ …

I wrote the wrong numbers down for 3dmark99, even at 350MHz the P2 doesn't get those scores. I was writing notes down on paper over the course of a few days working on it during my lunch hour. The other numbers look more legit but maybe I should redo everything. 1839 3dmarks and 2330 CPU 3dmarks at …

Couldn't find any old reviews comparing both chips at the same speed(except for the 686 comparison on Vogons normalized to 133) All the reviews at Toms, Anand, etc, were compares at different speeds. The first P2 and the last P-MMX were the same clock speed, 233, I was wondering how much of a …

You are fine with the 250, it's more than enough.

Most manufacturers offer a boot disk to install a LBA/CHS …

If you do go for make sure you do some good before and after testing, can you also take detailed pictures of the CPU and heatsink surface before and after?

Which model P4 is it? 3.2 sounds like the last of the V8 Interceptors... I mean P4s. It would be a shame to destroy a piece of history. If you clean the CPU & Heat-sink then use a quality thermal paste I don't see how sanding it would improve heat transfer much if at all. I remember back in the day …
