Enable the other 2 MB of cache on 6300 or 6400 B2

[yiranhu]

Hi all,

This is just a curiosity: 6300/6400 B2 has 4 MB of cache on the chip yes (just 2 mb disabled)? I read how people did the pin mod on E4300 to fool a computer into thinking the processor has 266 MHz bus. I wonder if there's such possibility for E6300/6400 to enable 4 mb of cache. For instance, the 6350/6450 are coming out soon and those will have 4 mb of cache. There's a chance that those are the same as E6300/6400 except the other 2 mb of cache is enabled.

Just a curiosity...

Any input is welcome...

I doubt it, it seems to me that the stock FSB is more of a firmware setting and the cache is a hardware setting, besides the FSB is changeable in the BIOS anyway, so at least we know it's already possible without a pin mod. Then again, it's possible to enable disabled pipelines on certain video cards, but those are more programmable than CPU's, but I dunno. The real trick is figuring out how to do it, since, unless I'm mistaken, nobody's enabled disabled cache on a processor before. Perhaps a pin mod would fool it into using the cache?

Have never heard of anyone doing this so I'm guessing NOPE.

I reckon no chance.

About 5 or 6 (possibly 7) years ago, that was possible to do. Then the cpu makers figured out how to keep it from being done, and nobody has done it successfully since.

People used to take old Durons and enable the cache on them to make them Athlon XPs. However, now I believe both Intel and AMD laser cut the disabled caches so things like that can't happen.

they are releasing the 6320 and 6420 which will have all 4M L2 enabled for the same price or cheaper next quarter I believe.

Plus it might be disabled for a reason. Could be faulty.

No way.

It is done inside the die, soldered.

 

[yiranhu]

well it was just a curiosity. Even if that were possible, I doubt I would do that LOL. But it just seem like such a waste to put all those hardware in there and simply disabling it. But I guess product differentiation is vital for any industry...

could be bad e6600's that didnt make the cut. same thing with thorton->bartons and applebreds->tbreds, but they worked anyway

Could be. Or they just need some thing to satisfy lower end consumers. I'm pretty sure that there's a large portion of the 6300/6400 that could have been 6600, 6700, or 6800. But if they made all of these into 6600,6700,or 6800, then their profit will suffer because not that many people have the money to spend on these higher end models. But if you sell them cheaply but limiting something (i.e. multiplier) people are going to buy it.

Just like cars really. Toyota camary is almost the same as some higher end Lexus in terms of the major components (engine/transmission/.../door LOL). But they target different sector of the market so Toyota has to choose how many of each to make that would generate the highest profit.

that's the most common cause. the setting is fused.

I would kill for a mod to up the multi on the e6300!
