Barton question

[jpnelson83]

Are the barton core processors still coming with the multipliers unlocked or did they start locking them? If they are coming locked now what do you need to do to unlock them? I'm looking to get one soon but I don't want to overclock right away but it would be nice to know what I'm gonna have to do if I want to start overclocking. Thanks guys.

I think the Mobile Bartons are the only ones that are unlocked now. People have been getting good overclocks with the locked XP2500+. Mine is at 11x210 on an Epox 8RDA3+ rev 2.

I don't think there's any way to unlock the xp's now, but as mentioned above, the athlon xp-mobile chip is what you should look into. Lower stock voltage (1.45v) and more OC headroom in every case it seems. 2.4-2.7ghz are being reported

Has anyone ever upped the FSB on their moblie barton to 333 MHz?

This deserved to be sigged...

Are you serious? lol

I thought you could connect the one bridge on the desktop bartons to make the board think that they were "mobile" cpus and hence, and unlokced multi.

correct me if i'm worng

Hmm, maybe I can help here. Are the reported FSB's of processors doubled like that of ram? So 266 is actually 133 and 333 is actually 166? Thats what I was trying to ask. I wanted to get a Barton w/ a 333 FSB cause my board will only support a 333MHz proc but since the only over clocking I can do is by upping the FSB I'd like to go with the Moblie route. I know that RAM likes to be in sync with the processors FSB so I'm getting some Mushkin PC2700 Lv2 from the egg. Hmm, hope that clears things up a bit.

As somone who has never overclocked anything, yes I was being serious. What is the highest FSB someone has gotten a mobile barton too that ran stable?

FSB will go as high as the board and memory allows. Pair a mobile with a high FSB board like the Infinity/LanPartyB and some BH-5 RAM.

I have never heard of a AMD board that only supported 333mhz fsb. Let me clarify

Yes, the FSB is DDR, just like the memory frequency is DDR.

Therefore a 266mhz chip is 133x2, same way PC2100 RAM is 133x2.

You get a chip with a 333mhz FSB means 166x2. As you know, the best way is to run the memory in sync, which would be 166x2=333mhz (pc2700).

If all you are planning to reach is 333 then PC2700 would be a wise choice, if the price is significantly lower than PC3200.

However, if you are like most people, you'll want at least 400mhz FSB. For this you want PC3200 or higher.

Just because you get PC3200 doesn't mean you can't run it slower (pc2700/333mhz) if you choose. You can buy PC4000, which is like 250 x 2 (yes, 500mhz DDR), and run it at 200mhz, 166mhz, 133mhz, etc.

And likewise, you can run PC2700 at higher speed sometimes, but it's not a safe bet in my opinion. Go for at least PC3200.

The mobile chip being unlocked will give you very nice flexibility in your FSB x multiplier settings. Therefore you want as high FSB as you feel comfortable. For me, it's 200mhz (400DDR).

Thank you for your help. When I said my board will only support a 333 MHz chip what I meant was up to a 333 MHz chip I am currently using a 1900+. I have a gigabyte GA-7VAXP and it will support DDR400 memory but not a 400MHz FSB chip. I really dont have any desire to go over a 333MHz FSB so I'm not worried about my RAM.
