Just changed the multiplier on my XP1800+...

[Confused]

I have the K7S5A m/b, which most people know, has no multiplier or voltage adjustments, and limited FSB!

I decided today to see how much higher than my previous 1686MHz (146.7x11.5) i could get my AGOIA "9" 1800+ to run.

It all started by lapping my FOP heatsink See this isn't it shiny! 😀

After consulting the OCInside.de XP Painting guide, came the next daunting task, which was to cut some of the L3 and L4 bridges. I didn't get a pic of that cos i didn't want to possibly slip when holding the camera and dig too far into the CPU! It's quite daunting cutting into a £60 CPU with a Stanley knife! :Q

Then it was the task of joining the relevent L3/4 bridges with the master of all Athlon unlocking, the mechanical pencil 🙂

The 12.5x multiplier was selected, CPU reseated, the computer fired up and et voila, it POSTed as an Athlon 1250 😀 Changing the FSB to 133 gave me the 2000+ 🙂 FSB was pumped up to 143, the highest it would POST at, for 2200+ baby!

This would not get into Windows, unfortunately 🙁

So, i knocked down the mulitplier to 12, and it booted again (after resetting the BIOS) at 1200 🙂 Changed the FSB to 146.7, and again POSTed at 2200+ (same pic as last one in case u didn't click 😉) This time it got into Windows, where the CPU speed was noted as 1760MHz 🙂

So i went to click on the Start menu to get the Run command to bench UT2k3, and it froze as soon as i touched the mouse button 🙁

Knocked the FSB back down to 143 (the only other option, remember i have a K7S5A with very limited FSB speeds! 😉) and booted straight up at 2100+, and am still in Windows over an hour later at 1711Mhz 😀 (Screenshot taken 18 minutes ago, time taken to write this and upload pictures 🙂)

Not too bad, will see how she does at Seti now 🙂

WTG, nice modding Garry 🙂

I haven't even ventured into messing with the bridges yet. Old ASUS MB running at nearly 300 though with this AGAIO 1600 1.4 chip running at 1.55 2X148 (296 FSB) , awesome for the price $50 U.S.

nice job!
but im a little confused about "Mechanical pencil" - is that simply graphit pencil (0.5) or smtg else?
I thought that xp's bridges (L3 and L4 ) cannot be modified with graphit pencil bcause of high resistance???
if it can be modified with graphit pen let me know! 🙂
i would like to unlock my xp too 🙂

Yeah that is the same as a 0.5mm graphite pencil, i was just tryin to sound flash 😉

And everywhere i read says that you can't use a pencil on it cos of resistance! But i'm doing it and it's working OK, so i'm not complaining! 🙂

What i needed to do was make sure i really worked the graphite into the little pads for each bridge, to really make sure there will be contact, and if it doesn't work right take it out and try it again 🙂

I see you use "Colgate Total". Its good... I use it too 🙂.

lol
nice, so i just need to be carefull when joining bridges and thats it!
i own k7s5a too, did Vcore mode, Vmem mode and clocked xp 1600+ at 10.5x147 fsb= 1540 mhz (1800+), cpu vcore is 1,9v, and it works nice for months!
now i want to try 11 x 147 fsb to get 1900+
well i have some exams right now, but as soon as i finish it i'll do that mode!
btw for k7s5a is possible to make multiplier adjustable with switches (i think that u already know that) 🙂

Here

thx!

Nice overclock Garry!:Q😀

I chickened out of cutting my bridges on my XP1500 ,as it happened I didn't need to,to go to XP1600 all I had to was join to join 1or 2 more bridges🙂
(as for the L1 bridges I screwed up the insulating area at 1 end!😱🙁)
