Well I replaced my trusty, but rather warm, 1800+ in a rev 4 Gigabyte GA-7DX with a brand new Barton 2600+ mobile. Gigabyte's website showed a new BIOS that would support up to a 2600+.

Alas it wasn't straightforward.

The new BIOS did not recognize the Barton and so it started at 800MHz.

I tried Easytune, the official "tweaker" from Gigabyte but that wouldn't allow me to do anything but up the system bus. I didn't want to o/c anything, stability is everything else my daughter would lose interest.

Then I dloaded CPUMSR but then the notes said it would not run on Win98 so I upgraded to Win2000, something that I was planning to do anyway as we do video on this machine and I wanted NTFS.

More grief as CPUMSR froze everything when I tried to change the multiplier & voltage.

I was thinking that perhaps it was a limitation of the m/b but I dloaded CrystalCPUID. What an amazing program! And for free!

It changed the multiplier and voltage without any problems, so now its running at 133x15 == 2GHz, 1.45v. Its fast and cool, the m/b temp sensor says it 20'C cooler than the old 1800+. CrystalCPUID can also be command line driven so I can have an icon on the desktop to change frequency as and when I want - one button says "15.0x", another could be "6.0x" but as its so cool I'll leave it at 15.

Took me an evening of work but its worth it, especially with summer coming and the room will be so much more pleasant to work in.

Hey mcmab, yes CPUID is definitely a godsend, and I thank people on these forums who told me about it. I have the 2600+ too in a Compaq Presario notebook. The limits of each cpu is different, but I'm getting mine to run at 15x on 1.3V. And the lowest voltage (0.925V) on CPUID allows me to keep it at 9x. Manipulating the thresholds, my comp runs at 1.2GHz while idle at a cool 34C. That's about as hot as my hard drive gets. If you ask me, this is way better than PowerNow. (Stability was tested running Prime95 for 12+ hours).

Well everything is running fine, all the USB & firewire stuff and there's a lot here, and I'm growing in confidence with it.

I really like the speed increase on video editing. It crosses the line from "just fast enough" to "its a pleasure to use". I would recommend this as an easy excellent upgrade that you really notice a difference with. How many upgrades and you can't feel THAT much difference (hey I'm still using my K6-III here and I love it because it is the best machine for general office stuff).

I won't o/c anything but I may try dropping the voltage a bit. Most of the heat is now coming from the other parts of the system, not the CPU.
