Which AXP CPU will OC better, 2000+ or 2100+?

So, "big difference...", you say.
I just bought a cheap SFF, a Biostar 210V and I'm going to cycle one of three processors I have in systems that the customer canceled on.
Two are 2000+ and the third is a 2100+ AXP's.
I've heard the 210V isn't much on overclocking as it doesn't have an AGP lock, so it's best to use an AXP with a default 400fsb and the same with the memory.
However...
These three cpu's are not locked and all come with a default 266fsb. My shelf memory is 333MHz so I'm thinking of a 333 system and maybe clocking the multiplier as high as I can, retaining stability of course.

Does upping the fsb cause an unlocked AGP to go bad?
 
Actually, I've had good luck in the past with running the AGP way out of spec. My old GF2 ran perfect on with an AGP bus speed of 89Mhz (the default is 66Mhz). This was on an old Abit BX board that only had a 2/3 AGP divider and I was running a P3 @ 133 FSB.

I'm not sure about how well current video cards run on an overclocked AGP, though.

As far as the chips go, are those Palomino or T-bred chips? If they are pallys, they won't OC worth crap and wouldn't even try. If they are T-breds, then you've got much, much more headroom.
 
Try to increase your fsb all the way to 200mhz and lower the cpu multiplier as you need. At 200mhz the AGP should snap into another divider bringing it back to 67mhz.

I just bought a SFF Biostar 210V and I've looked inside the bios but can't find an adjustment for the multiplier.
There are jumper settings to set the cpu at 100/133/166/200 fsb but the system reboots if I set it to 166.
The default fsb of this 2100+ Tbred is 133 with a multiplier of 13. If there were a multiplier setting in the bios I'd down it to match my PC2700 1:1 and OC the cpu just a bit.

I did, however, buy this for just an office and surfing box so for that it'll be just fine as it is. If I ever find a home for this cpu I can always purchase a cpu with a 400 fsb. I suppose I just may need some PC3200 DDR but perhaps not.
 
not sure if this is irrelevant or has already been said 🙂

I have a 2000+ tbred, and have run it @ every possible combination that my A7V8X mobo allows, (tops 182mhz fsb cos no PCI/AGP lock, it was interesting running it at 180*5 and the like 🙂 ), but find it a lot less hassle and no probs (usually HDD related when running out of spec i found) just bumping it 2 166mhz and playing with the multi. I usually leave it @2600+ (166*12.5 i think...) and vcore @ 1.675, to go much higher need to bump the vcore up & it gets a bit warm 😛

Also as said above, if they're not t-breds u wont go far with your oc attempts :laugh:
 
I would get a mobile barton but both chips are good. Neither can really definately OC better than the other one.

As for running the AGP/PCI bus out of spec. It is not reccommended and it can fry the motherboardm, but you will notice unstable operation before you fry something. I wouldn't overclock too far.
