on the Xeons, the L3 cache is on die too, not exactly why they just don't increase the L2 cache instead, I might find out why after taking my VLSI course in a year or so though.

Yeah, it's the L3 not full speed on the Xeons? That would just not make sense if it was on-die, just beef the L2 instead.

it's full speed but there is the issue of latacy (sp)

L1 is the fastest because the time it takes for data to go from L1 to the execution is the shortest

L2 takes longer than L1 and L3 takes longer than L2 and L1

I think there are design issues associated with the size of cache, not exactly sure.

Intel 1100 MHZ CELERON SOCKET 370  CHECK that out... MORE L2 CACHE ! HAHA !!

I found this on Ebay

I am sorry, you are right, i guess all the time i've spend in electrical engineering are wasted since i can't even tell the difference between on-die cache and capacitors. All of us just lie to you so that you won't able to mod your celeron

You should able to get up to 2mb of l2 cache by getting used up "cache chips" from older celerons (probably can get it for really chip) and solder it onto the back of the chip

I suggest you go one cache chip at a time, just to make sure the cache chips are good

tell us how it goes okay.

Those are still capacitors. The 1.1 GHz Celeron has a different electrical configuration than the one you have.

LMAO Kawai do i sense a "hint" of sarcasm?

Electrical engineer types (like us) are full of pooh and it takes a kiddie to tell us the way it REALLY is eh :woot: ive wasted 13yrs at this caper I think i will become a lollypop man now :rofl:

Couldnt he just buy a bag of l2 cache from Cache R Us? (not the prepacked l2 cache cos thats generic crap go for the ?9.99 per kb loose variety wouldnt that do it or maybe superglue some AMD l2 cache (intel l2 cache wont work cos of the lack of an internal flux capacitor)

:woot:: :woot:: :woot:: :woot:: :woot:: :woot:: :woot:: :woot:: :woot:: :woot::

To the original poster STFU you moron proper techys are trying to help you and like a retard you are basically saying hes full of sheeeet. Oooh u found a chip on ebay with what you want, its on ebay so it MUST be true! (some people jeesh cos they read it on the net it MUST be true)

heres one for you then ELVIS LIVES!!! its true cos i read it on a website.

get a grip you ###### ?

Capacitor Definition

A capacitors role in electronics is to regulate and smooth out the Voltage passed through it that my dear chump is what you see on the bottom of ALL CPUS. all intel cpus since Cumines (coppermine) have cache ON DIE (e.g. under the metal shim) including all celerons after 550s. (550 and below are pII cores)

AS previously posted think of them as a smoothing out battery or inline conditioning unit for the voltages on the die.

Every different type of cpu on the same die will have a number of different capacitors on the BOTTOM of the DIE depending on the power input requirements, thats why some have more than others.

The original poster cant take No as his answer he knows best despite everyone else being bound by the laws of electrical engineering, physics and electronics. He is special as these laws dont apply to him. He should contact intel im sure they would have a special job just for him (head carwasher probs)

:yes:

As has been said many, many times, the cache is integrated into the die. If you really want to waste your time soldering some more capacitors onto the bottom, go for it.

It may be worth pointing out that even Pentium 4 processors have capacitors underneath. As many of you will know, there are 12 cap and 30 cap versions. Regardless of whether it has 12 or 30 capacitors, it still has 512k cache. Hopefully that example will help you understand that capacitors are NOT cache.

The only processor I'm aware of that has been possible to re-enable cache on was the Applebred core Duron, where joining a bridge or two with conductive paint will give the processor 256k cache instead of 64k. This is because the Applebred was a reject Thoroughbred core. However, as has already been posted, the Coppermine128 core used on the older Celerons is not a reject Coppermine P3 - the cache is physically not there.

More to the point, what's the purpose of enabling extra cache on a 3 and a half year old CPU anyway when you could just purchase a faster socket 370 chip for less? Also, if it was really possible, do you honestly think that nobody would've figured this out 3 years ago?

Another point - the 1.1GHz Celeron is still Coppermine128, therefore has 128k cache still so in posting that picture, you've proven yourself wrong. The Celeron 1.1A and over are Tualatin cores with 256k cache. That picture you posted is clearly a Coppermine128 Celeron because of the size of the capacitors ... if you saw a Tualatin one, you'd know - there's a lot more capacitors on the bottom and they're a lot smaller than the Coppermine ones.

ur an idiot for arguing like that with people who oubviously knew much more about cpus than u........and i should give you a medal for being the first idiot who thought u could add l2 cache to a cpu LOL

dude, your wrong. cache is embedded into the core. done and done.

LMAO thats good! :p

yes would the poster kindly SHUTUP and ACTUALLY STOP BEING A BLEEPING PARROT.... YOU DONT HAVE TO REPEAR THE SAME FALSE INFORMATION 20 TIMES :angry: (really wishes i could make really funny comment here, shame i'd prob get kicked off neowin for it though :cry: )

*rant over* *goes to get another beer*
