Overclocking question; need help fast...

Ok, so we all know about the JIUHB DLT3C 1700+ cpus. Woohoo.

What about the 1800s? I've never even heard of 'em... I just bought 2 KS75A/1800 combos @ fry's for $59/ea (one for me, one for a friend) and the CPUs have identical steppings...

The entire code is as follows:
AXDA1800DLT3C
JIUHB0321XPMW

So it's still a JIUHB DLT3C, but it's an 1800, not a 1700. I haven't cleared a space on my desk big enough to plop the halfway-functional A7N8X (Yea, I RMAed it... they sent me a defective board and I haven't sent it back again yet) onto it and test the thing, but I'm in need of a quick answer here because @ $2 over newegg's price for the retail 1800 alone, these things aren't gonna be around for long. Especially not if all/most of the cpus are dlt3c jiuhbs and people realize it... If these things OC well, I might buy 2 more, but I don't want to buy them if they won't OC...

Help, anyone?

    I don't know from personal experience, so take all this with a grain of salt.

    One theory on overclocking is that it is easier to overclock a CPU of a given core when you have a chip that is early or in the middle of the life of that particular core. The idea is that since all of the CPU's with that core are basically identical, with only subtle differences between them, a chip near the end of a cores run (at a higher MHz rating) will be pretty much maxxed out already.

    Since the 1800+ is right in the middle of the seven palomino's, I'd say you stand a fair chance. I know as soon as I say this someone is going to tell me about getting fabulous OC's from a 2100+, but the odds are that the 1700+ to 1900+ CPU's stand the best chance.

    The difficulty here lies in the fact that we are talking about averages - what an individual chip will do is anybody's guess. I'm pretty happy that I've been able to run my Thunderbird Athlon 1200 at 1333MHz to 1400MHz, since that particular core maxxed out at 1400MHz. Since you've still got 200MHz of headroom in that core (300 by the PR rating measure), chances are decent that you'll be able to crank it up somewhat. Of course, getting input from people who have actually tried it will be more valuable than any theory. :p

    Yeah, well obviously no one will be able to tell me exactly what the chip is capable of (I just left myself wide open for Thrax or Leishi or someone to come in here and do just that, didn't I?) but I'd assume it should OC as well as the 1700s since it's the same... exact... core.

    ...but to me, having the exact same stepping would make me optimistic. :thumbsup:

    For $59 you can't go too far wrong.

    Edit: I missed the part in your original post about getting the MB's too. Jeez, you could probably sell the boards for half what you paid for the CPU's and end up with $30 processors. Too bad we don't have Fry's around here...

    Yea, I'm not quite sure what I'm gonna do with the board yet. I mean, I could sell it, but it's a perfectly useable board too... but I won't be using it, I mean, I ALREADY have a KX7-333 and an A7M-266 that I'm not using (along with a 1700+ and a 2200+, and another 1700+ when I drop this 1800 in my A7N8X...)

    I would believe that 1800+ you got should do exact same as a 1700+ with the same stepping, but for that stepping, i think it should do 2.4gh ish with 1.85vcore, maybe little lower or higher.

    Reason people buy 1700+ is because they are cheaper than 1800+ , and if they find a good stepping, they can oc to like 2.5gh, and you might find a good stepping in 2100+ and oc to the same speed, then why pay more when you can OC them to about the same speed?? So that's why a lot people are buying 1700+ instead of 2100+ or 1800+.

    I'm going to plop a shot in the dark and say 2.32GHz on about 1.725-1.775v or so.

    If anything, the higher OOB rating on the chip means it was fabricated from silicon closer to the center of the wafer, so you might find it's a better clocker at lower voltages than a 1700 is.

    Only experience will tell.
