how to enable 512KB cache for an unlocked green thornton

coscos · Dec 19, 2003

Just got a AQXEA 0334 green thornton. Tried on A7N8X DLX and it is unlocked! However, I tried to enable the 512KB cache but failed. The L2 bridge looks different from the article on xi labs.

Can anybody give me a clue how to enable the 512KB cache? thanks. I will upload some picture of my CPU if necessary.

a picture or two might be very helpfull since you stated it looks different...

On the green package the bridges are covered with a thin layer of plastic, so if you just use conductive paint on top of that it won't contact them. You need to gently scrape off the plastic top first and expose the tracks underneath.

could you give me more detail? how to do that?

By the way, here the pictures for my CPU and L2 bridge:

I missed that the processor is unlocked in your initial post.

Is there a "Fake PCB" covering the bridges? If so, then dig it out with a thumbtack to gain access to the L2 bridges you need to connect. Since there is "Fake PCB" material covering the fround plate, and burn, between the bridges, you can just connect the L2's with conductive ink, or Window Defogger Repai Paint.

In the bridge picture you attached, the L2 bridge (the first one from the left) that has the burn mark (visible as a little brown rectangle) betwen the two little gold dots is the one you need to connect. The burn mark has a ground plate below it, and you need to make sure that you *DO NOT* connect either of the bridges to that plate when shorting the L2 bridges.

If there is no "Fake PCB" then you need to fill the Burn hole with White-Out, and let it dry (leave the two golden dots uncovered). Then use conductive ink, or "Quick Grid" Rear Window Defogger Repair Paint to connect the two little golden dots. Let that dry, and then test it out. If it worked, and the full cache is available, then you might want to seal the bridges with some more White-Out, or with some clear Laquer.

Good luck! Tell us how it goes!

If I'm not mistaking, judging from the pics that you uploaded, you just filled the gap with conductive material, right???

If this is so, then it's no wonder that the mod didn't work! Take a look at this howto and then try the mod again:

This method worked for me on one Duron and 3 Thortons already.

But keep in mind that you could also have a chip with defective cache.

I filled the gap and I connected the two pads with conductive ink. In order to take a picture, I removed the conductive ink. That's why you didn't see it there. Thanks for the reply though

Just read the link you gave, very helpful information. But I am a little bit comfused: if we scratch the laser hole untill we see the copper, and fill it with conductive ink, then why not fill the hole directly? Also, after we see the copper, do we still need to fill the gap with some inconductive filler?

thanks.

Does that mean I don't have to fill the gap with any inconductive filler? So I can apply the conductive ink directly (after the digging)?

so I'd better fill the hole first and then connect the L2, right?

I'll try it tonight and let you guys know. thanks.

Let me try to explain what you have to do. You gotta get some Conductive material (to connect the dots) and some NON-Conductive material (to fill the pits). Then carefully scrape away using a pin the dark green dots till you see copper, when you're able to see the cooper on both dimm (the inner) dots then clean the bridge up w/ some acetone, fill the pit and the close up the bridge with conductive material

No, you still need to fill the little brown burn hole with non-conductive material to avoid killing the processor.

Click to expand...

Yes - exactly. Fill the hole with non-conductive material.

Celemine1Gig · Dec 20, 2003

You don't need any non-conductive filler at all if you use the method that is described in the link I gave to the ocprices.com site. You just have to scratch the edges of the little laser cut pit a bit, until you see the copper shining. Then clean the pit ad then just fill it up with conductive material.
That's all! Worked for me on 4 CPUs already

No need to do it in a more complicated way.

thats the extact same chip ive got in a Asus board in my mums b/fs comp running at 2800+ speeds fine i havent unlocked the extra 256k cache tho

coscos · Jan 13, 2004

finally got a chance to post my result! I got a 512K L2 cache now! see the screenshot of cpuz.

I created a visual instruction at my homepage . hope it is helpful to others.

f00t · Jan 13, 2004

great guide you made there. very easy to follow

coscos · Jan 13, 2004

by the way, anybody where to get an extra side panel for my case? it is a Enermax CS-1251-B.

how to enable 512KB cache for an unlocked green thornton
