Hey all,

Just thoght I would share an experience I had over spring break while upgrading my dad's computer. He had a duron 700 running in his Asus A7V (my first overclocking board - great piece of overclocking goodness). Anyway, after checking out some posts on other asus related boards I decided to order him a 2100+ for his aging board. I was a bit worried about how to get the combo to work, but after some time and a few attempts, I finally got it up and running. And boy does it run. At stock voltage (1.65v) it was able to pass 24hrs of prime95 torture test @ 2.2ghz w/ the retail heatsink that I got with my barton 2500+ (the 2100+ was an oem chip). What was great is that newegg must have had old stock because I got an unlocked week 18 of 2003 core. This thing overclocks like nothing I've ever seen. I kinda wanted to give him my unlocked barton and take this thing for myself. I have no doubt it would do 2.4ghz in my board w/ proper cooling. It had no problem running prime for a few hours at 2.3ghz w/ just and extra .25v. However, with noise and cooling being an issue, I decided not to go for the extra voltage.

I also thought I would mention this because I know the A7V was one of the most popular overclocking boards back in the day (well not that long ago really). Many of you may have one laying around. Upgrade to the new 1011 bios and you have support for pretty much anything. Now, it does use the via kt133 chipset so you are only running a 100mhz supported bus (though rumors appear to be true that you can flash with the asus kt133a bios and get a completely functional board w/ 133mhz fsb; however extra northbridge cooling should also be added). If any of you have one laying around and need a machine to do some normal office type stuff this is a great idea! Wow... sorry for the long rant... I'm just quite happy!

that board rocks
i've overclocked athlon xp's on it too
got a 2400+ to 2.53ghz on that thing
you can mod the bridges on the chips too to unlock higher clock mults

unfortunately you can't make the kt133 chipset run much higher than about 105 to 113 fsb regardless of what bios you use in it (unless you were one of the lucky few that got a kt133a chipset on one of the later revisions before they all started being kt133a)

100 fsb is still plently for many things like seti, office apps, old games, etc

the a7v was one of my first overclocking boards too
nice oc you got there !!

Soulkeeper - awesome overclock yourself! I think I'm going to try to pick up an extra A7V on ebay if possible... they have refurbs for like $20. Mine is a rev1.02 so definitely dont have the kt133a but I didn't even try to run the fsb at anything but 100mhz. Shame too because this crucial pc133 will do 150mhz cas2 on my other boards! Lol... I wan't another box to just crunch destr comp projects all day!

yeah i would try to get a kt133a motherboard if you can
i just picked up an msi k something turbo (kt133a for 20 bucks) and it wouldn't let me overclock at all ( got it at justdeals.com you might wanna check that site out to see if they get an a7v in stock)
the asus and abit kt133a boards are pretty much our best bet for the old pc133 mem we all got laying around

lol ive got my xp1800 running at 1804 mhz on a kt133a, 157fsb. msi k7t turbo2 is a good overclocker. i have k-bit pc133 running at 157 cas2.

I'm going to have to get another one of these chips for my brother... he has an Iwill KK266-r. I forget the chipset... but I believe it might be a kt133a now that I think about it... definitely is VIA... uses pc133... sounds like it to me :)
