I just got my new Barton 2500 along with NF7-S and corsair twinx. I was gonna try to OC a little. Now I'm reading the chip have the multiplyer locked. I'm feelin screwed-beware if this true

Can you change the fsb in Bios?

Re: Hardware Boss. I hear you can't. I've almost got my new system together, but not yet. Once done I should be able to confirm

Re: Wussy See above. Yeah, its what others are reporting or what I'm reading. But like with you guys I tend to trust to what you write/say (particularly when others on the forum confirm it). At this stage I'm too much of a nOOb to view the chip closely and make much sence of it. That will just be another project for down the road a bit. (btw, I'm pretty sure they said the bridge was connected but no luck w/multiplier-those at the other forums were trying to figure it out still last I read.)

Test your Barton first and then you can really see what's going on with your chip. I really doubt that it will have its multiplier locked though, don't worry.

On the other hand there is a little something I'd like to comment on:

I don't see the reason for this. Disappointed? Sure! But screwed it's not the right word to use. It's not like AMD sells these chips with a guarantee that they will work 30% faster than their advertised speed.

Wats the stepping on that barton 2500?

hmmm. Maybe this is a sign that i should wait for the 90nm bartons :smile:

has anyone proven they've had a new barton thats been locked? or a website with this reported, or anything? Also, what new bartons is it? model # _____? what way can you tell? GUH?

...Meh, too lazy to think of a better sig.

Barton 2500 (AQZFA)@11.5*200(1.7v)

A guy in the cpu overclocking forum reported that, obviously you can change the multi on the bartons.

Don't get me wrong, but I think the best way to overclock a 2500 Barton is to overclock the <b>FSB</b>, not the multiplier. The performance gain is higher than pumping the multiplier, and nForce2 mobos garantees that PCI and AGP buses run under spec.

I don't know, do you have numbers?

I've built 12 A7N8X Deluxe's now & have OC the multiplier on everyone of them to 12.5. That gains 1200 3Dmarks in 3Dmark 2001 SE. However when I try & OC the FSB, even with Hyper X RAM, I can't carry 200 FSB with the board timings set to aggressive. If I back down the timings on the board, I can pull a 200 FSB, but not get as many 3Dmarks. Not only that, but I believe the North bridge heats up & you have to wait for it to cool down to make another change to the FSB. Keep resetting the CMOS every time it fails & then wait for it to cool back down.

No, I believe that a 12.5 multiplier run @ 2800 speeds is all gravy for the 2500 chip especially with stock cooling. The hottest one I've had multiplier OCing is 44c under load. Mine runs 41c under load. I had one that went 38c under load. So, it's all good no matter which way you go. I just fell it's better & safer to multiplier OC, myself.

I picked it up off overclockers forum last week. There and at Anandtech you can find a list of the CPUs that are locked

I was'nt lookin for a guarantee that it would do 30%. But I did sh*t pile of reading up and wanted to play with the Barton including changing of the multiplier. In fact, there are specific OC'ing suggestions (from members here) that I intended to pursue that invovled increasing the multiplier.

Now, if they had announced the change-fair enough. Disappointed absolutely, screwed - I think its fair to use the word, cuz with no warning they changed the product.

My original post was intended to warn others who were pursuing the path as I. And judging from other posts in various forums the Barton/nfORCE/quality ram combo was popular. For those of us who caught with a product change after order we'll just have to make due. IMHO, that sucks

That does suck for sure. I'm going to have to find another favorite chip for my clients now. That 2500 was so sweet too. :frown:

Yeah thats a new stepping line. Wouldnt doubt that they would start locking the multiplier again to push people toward their faster and more expensive bartons. If they L1 cache bridges have been severed, could get the kit for that.

OK, I'm going to try to post a link to the site where much work looks to have been done re: locking of AMD chips (not only Bartons but Thorntons as well)

It's not just crappy Nforce boards, can't change multiplier in any mobo
It's not just this new stepping
Its not the bridge thing

It doesn't seem to have been solved as to how amd is locking the multiplier. Hence, cannot yet figure out how to circumvent. This site seems to be a global forum for amd freaks/gurus. If your'e interested in this topic I recommend this site:

I think that most people here seem to forget something really important! The Barton 2500+ has multiplier 11. So, anyone who has a 2500+, the first thing trying to do when overclocking is raising the FSB to 200MHz, since that's something very easy to do with an nForce2 board and PC3200 memory. This way, you have a 3200+ CPU in your PC for almost nothing, without even messing with the multiplier. Nothing has changed! Also, because I am one of the Barton/nfORCE/quality ram combo fans you mentioned, those with good quality ram can also achieve higher speeds (2.3GHz and above) by raising the FSB to 210MHz, 215MHz or 220MHz (whatever each one can achieve).

So all of you that have PC3200 memory and nForce2 mobos, locking the multiplier of Bartons doesn't affect you in any way. Most probably you wouldn't mess with the multiplier anyway, when overclocking the 2500+.

Bottom point is. Barton 2500+ remains an excellent choice for overclockers.
November 13, 2003 12:18:17 PM

That's true IF you have a nforce2 mobo. I was plannig to use a 2500 Barton with my KT266A mobo. Changing multiplier was something I was looking for, even I know that mobo by default can do it (research involved :wink: ). But if the CPU is looked, there is no way!

That sucks! :_(

Thanks Pitsi. Although I intended to play with changing the multiplier, if I can get to 3200+ w/o it then I guess I'll be satisfied. I guess in a way I'm lucky because I did get the NF7-7 and high quality ram. Unfortunately, had to RMA the mobo cuz it would'nt recognize but 1/2 the ram, then it decided not to post etc. Maybe I'll get the new board next week so I can have a go at 3200+.

My friend just received a Barton 2500+ retail today for his ABIT NF7-S and it is <b>locked</b>! You're right.

They ARE locking them now. This was reported on OCWorkbench.com also. It's NOT just cheap boards. It's ALL boards.

I'm a lucky chap to have mine not locked (doesn't matter as I just raised the FSB to 200 anyway)
