having problems unlocking...

[slick306]

So I have tried about 3 times to sucessfully unlock. MY best attempt was my first attempt and I was able to get a lot of multipliers, even the 12x multiplier but I want to get the 12.5x multiplier because I know my chip can do 2000XP. I am using the defogger kit, can anyone give me a little guidance on how to make it easier? I am a getting a little frustrated because everytime I want to test it I have to re attach my heatsink, and it takes a while grr, any ideas?

Are you using defogger to fill the pits between the contacts? I haven't unlocked my XP1500 yet but I've heard mentions of bad results filling the pits with defogger.

There is a second copper trace at the base of the pit that will become grounded and render the multipler useless if defogger or some other conductive material contacts the copper layer.

Some people don't like Tom's Hardware but if you haven't checked out his guide on unlocking XP cpu's it might be worth a look (http://www4.tomshardware.com/howto/01q4/011112/index.html). I thought it was pretty darned informative! Good luck!

Have'nt done one yet either (xp) but the first victum is waiting in the bedroom. I think that I shall fill the pits with some 5 minute two part epoxy that I have and then give the defogger paint a go. What can a xp1600 do?

Check out the CPU Dbase (http://overclockers.cssftware.com/cpudb/index.cfm) and find out! :D

Edit: WOOPS! Only two entries...guess you'll just have to add to the list!

Well I used nail poish to fill the fits, however I thiink that most of it could have been stripped away by now after I keep rinsing the surface with alcohol. But I don't think there is any conductive material underneath, it is a burn mark from a laser, and remever I can get most of the multipliers... Oh, I am going to try scratchgin the surface of the l1 brdiges with a pin to get a better contact, I hope that works..

Some motherboards do not identify the 12.5 multiplier right.
They usually set it to x13 instead if your motherboard is one of the ones.

I use a magnifying glass...
fill the trench w/ super glue...
then use a conductive pen, ( using a sewing needle to connect the bridges.
It's worked every time like that...no complaints.:)

Taped up the trenches and filled with 2 part 5 minute clear epoxy. Am going to do the unlocking in a minute. Tis a son of a gun running this t-bird in the background under a stress test while surfing. It is presently at 2.33v , am looking for stability. Temp on chip has dropped one degree in the last hour to 43c.

WHoa, what kind of cooling are you using? Water er? those temps are really good for 1.774ghz.

Well when I took the DD block apart I cut a couple of small passages around were the heat sink on the cpu is located. Air temp right now is 22.1c and return water temp is 17.1c. I built a custom block for my new shuttle, 2.43 times the volume and .5x3.75x3.75 with three inlets and three outlets but alas (though it flows great volumes) the shuttle board arrived doa. Going to hold the xp in reserve for now (air temp just went up .1 and water temp on return just fell .1c) as I would really like to see just how far this 1.4 will go. Not looking for anything fantastic just 1.8.:)

And it just dropped to 42c with stability program running in the background. Air temp 22.2c, water 16.9c and cpu 42c. If it drops much lower I am going to get out and bring it up (or try to) a notch to 1.9.
