Higher multipliers with Athlon 1700+ and A7V333

[hominid skull]

I'm in the process of over clocking my new week 0319 JIUHB processor. I'm up to 12.5x168 = 2100 @1.5V (default voltage) but i can't raise the FSB anymore due to either poor ram or something else.

I want to be able to get access to the higher multipliers, i had them when i had a 2100+ athlon in there 13+, but now with the 1700+ i only have access to the 12.5 and below. As it is a KT333 board i don't have an AGP or PCI lock so i wanted to know if there was something i could do to raise the multiplier to 13?

This processor is the new package design where if you look closely at the chip you can see the traces.

Cheers in advance.

You need to unlock them...I'm sure somebody will reply about it but I, myself, don't have any links as this is something I would NEVER do (and is 2100mhz THAT slow?). It involves cutting/putting back together some of the bridges, or something like that...

Cut the 5th L3 Bridge to set the Multiplier HI bit:

See HERE

Cheers for the link, although with that site it's not too clear that cutting the last L5 bridge is the thing to do. I just need more proof before i go messing around with this CPU. Plus this CPU package is not like the older organic packages, you can see the traces when looking at the top of the CPU, what's all that about?

Trust me, I'm an overclocker.

Cutting the 5th L3 changes the value of the 5th multiplier bit. This has the effect of adding 8 to the value if the bridges were laser cut, like they used to be before Tbred B's.

For example, go to the link and choose 13 as the desired multi. Do you see? The 5th L3 is shown as needing to be cut. So for you, the only requirement should be to cut the 5th L3 and then you can set you multi to 5 to get 13, as it will add 8 to whatever you set in the Bios e.g.

5+8 = 13
6+8 = 14
7.5+8 = 15.5

Etc. The 8 value comes from the cut, job done.

ahhhh, i get it now...

Time to whip out the processor and give it a go.

Cheers.

//edit, how much pressure should i use in cutting the last L3 bridge? I have go a stanley blade, will that do in cutting the bridge?

Be careful. I used a continuity checker (on a multimeter) to see if I had gone through. DON'T CUT TOO DEEP. A mate of mine killed his proc doing that.

So, how about an update?

no update... hope all is well
