OK Folks, for all of you who have been waiting for a easy way of altering the Multipler, this one might be for you. But I have to say a warning before, you have to physically modify your CPU which can not be reverted so ALL warranys will be definitifly LOST!
OK after the disclaimer, let`s go :
the idea of this mod is to change the multiplier on the CPU by altering the L3 / L4 bridges. The mod I have seen before was the one described on tomshardware using a silver laque, but I found this procedure too fiddling and to error prone.
So here is my mod :
1. Stuff you need :
-simple scotch tape
-a very sharp and exact knife
-a short pice of a wire
2. The multiplier Table
First you have to decide what Muliplier you want. Here is a short one (WITHOUT ANY WARRANTY to be complete or ERRORFREE !!!)
MHZ L3 L4 mult
1400 oocc oocc 10,5 (XP1600+)
1466 ccoo ccoo 11 (XP1700+)
1533 occo ccoo 11,5 (XP1800+)
1600 cooc ccoo 12 (XP1900+)
1666 oocc ccoo 12,5 (XP2000+)
I had a XP 1700 before so I have decided to change from 11 to 12 and now we come to the tricy part :
3. The cut
Now you have to compare all bridge settings on your current multiplier with the one you desire. You have to cut through all the bridges that are closed in the original setting and opened in the new setting and this is the part that can`t be reverted !!
Take your xacto knive and cut the thin bride. If you take a close look an the CPU you can see the connecting wire in the bridge. The cutting itself is not very difficult but you have to be very CAREFUL that you just cut the bridge you want and take care of the "connector-pads" on each side of the bridge, they must be unharmed! I have done this with the tip of the knife so it was almost like a needle and I didn`t had any probs at all!
4. The rewiring
After the hard part of cutting here comes the easy part. Take a simple wire and remove the insulation. The wire itself is made of a bundle of very thin chopper-wires. You will be using one of these wires for connecting the bridges. Now take one of those thin wires and place it on the bride you want to close(the lengh does not matter, you will take care later on that). Fix the wire with a short pice of the scotch tape on the bridge. Now carefully cut the wire to its right lenght (next to the "bridge-pads"), so that only the to pads are connected and nothing else.
5. Thats it. Enjoy your new faster CPU ! I`ve done this in 5 !!! Minutes, that was really easy, everything worked from the first moment without any trouble, but I will do a heavy load test tonight, so that I can see if I have to increase the core voltage. Bdw. you can increase the core voltage with the same trick and if you want 1,850V you dont`t have to cut any bridges at all you just have to close the only open bridge on L11 !!
So Folks nice cutting and tapeing ...(take care of your fingers [img]smile.gif[/img]
