O\C an AMD Applebred 1.6

[SplinterDB]

I have the MOBO listed below it will lock the PCI/ACR and AGP at 33 and 67 Mhz respectively. Would it be better to increase the FSB with the room I have on DDR Ram @333Mhz or will I get better results unlocking multiplier and L2 cache (currently at 64k). I know some basics, but if anyone has better insight that would be great. Right now I am at 144 Mhz FSB a 9.2% overclock. The Vcore is rated at 1.65v default is 1.5, Can and or when should I adjust this? I can step Vcore in .1 increments in BIOS.

I don't know about unlocking the cache but if you can, do all 3, unlcok the extra cache, the multiplier, and crank the fsb as high as it will go then up the multiplier until the chip maxes out. Most of those applebreds do 2+ ghz don't they? Pardon my ignorance though, I haven't used a duron since the legendary duron 700 .

depends if the processor is early enough , you need 2003 week 38 or earlier for the processor to be unlocked and be able to enable the extra L2 cache.

there has been mixed results on unlocking the extra L2 cache on these processors. for some it was a success meaning it worked out well for others it caused the processor to become unstable

I have tested three Applebred's, one 1.6 and two 1.4's. They all hit 2GHz, one one of them 2.1 and another 2.2. They are had locked multipliers, so the 1.4's worked out better, with the 2.1GHz running an even 200MHz fsb speed. Don't sweat the L2 cache, all Athlons/Durons have a large L1 cache and the L2 doesn't give as much as a boost as some people say.

I've had them all, 1700+ and 1800+ t-breds, 2500+ Barton, 2400+ mobile and Applebreds. The 1.4 on a 200MHz fsb was sweet, alot faster than many Barton owners are willing to recognize.

Here is a little update.

I had to ditch some RAM it was ECC and my board doesn't like it. Running Dual with the 2700 (It is 2100)
In any case they run fine seperately. I can play with the FSB more and over or underclock the RAM as a 50%-200% range. I can lock the PCI and AGP.

Right now I am running: 1856Mhz

155 FSB
RAM @ 100% 310Mhz
Vcore up to 1.504

The RAM is at 91% efficiency.
It is running a calm cool 46C in fact has not changed much maybe 1-2 degrees under load.

Will post more tomorrow.

if the L2 cache doesn't do anything, then why did they increase the athlon xps from 256 to 512 bartons?

I'm not sure SISandra 2004 only rates a tiny bit from my overclocking that may be the difference. It is not much. Maybe I won't worry about it.

FSB is at a even 166 Mhz Clock is at 2004 Mhz and My temps are still under 50C full load. I'm impressed for a $40 chip it is getting up past the XP2600. She is Stable and cool. There is only a 3 degree variance in temp and Vcore is bumped to 1.525v.
:shocked:

Sounds really sweet, please do keep us updated on this. I'm very eager to see what this value chip really can do If you dont mind could you also throw in some benchmarks there?

 

[quickford]

I was thinking about getting one of those 1.6 Durons just to play around with overclocking it. I don't really have room for another computer right now but I might get it while Newegg has it in stock to save for later. I'm interested in the results too. Is it an A core or B core?

As I started reading this post I just knew your signature would have a rig with a Barton.

Read your own quote, I never said doesn't do anything, and besides it wouldn't be the first time hardware was improved so uninformed people bought it. (P4 Williamette, P4 Celeron comes to mind)

The performance difference is 3% between an Athlon (256k) and a Barton (512k) running the same clock speed and fsb. I have posted links several times proving this, use search or google to find it yourself if you have a hard time believing the facts.

I too run a mobile Barton in my main rig, but that doesn't make it vastly superior to the Athlons with less L2 cache.

I was trying to find the container it was sent in, It has been a while. I remember looking up the stepping and it is a B core. The laser cuts on the L2 cache are consistant w/ info on Toms's. Iwas geally stoked when I got it cause some people have gotten them up 3.2 (h20 cooled but impressive none the less.

Ahh Works done. Well it has ran for 24 hours with no hitch. Temps still mid to
upper 40's. I estimated that is is overclocked about 25%.

 

[quickford]

Awesome

 

[SplinterDB]

It looks like that is it. I tried to move up to even 167FSB. Danger Post, had to clear CMOS. If I jump the core volts would it give me more? I am at 1.525 and the core is rated @ 1.65. I can move up in .025 increments.

I've got an unlocked one you can have for $20 plus shipping if you want. I tried unlocking the cache unsuccessfully, but the chip still runs stably without the extra cache enabled.

For 20 bucks, it'd be hard to pass that up. Paypal?

 

[Zebo]

Durons are the best price/performance chip of all time. Even better than sub $100 mobile bartons. 100% less money and maybe only 10-30% less performance when both overclocked. I have no idea why everyone does'nt buy one for value systems. With less cache they overclcok even easier than both t-breds and bartons.

Try ~1.85 volts and 200 mhz FSB.

 

[SplinterDB]

The core is rated for 1.65v should i exceed that?

1.75 should be safe.

to enable extra cache, read this, it looks easy enough, 1 bridge
