Heights of overclocking AMD XPs

[Ilmater]

I was previously under the impression that XP 2100+'s overclocked farther, consistently, than XP 1700+'s. However, while parusing the forums, I'm starting to get the feeling that this is not the case. I'm looking at two CPUs:

This XP 1700+ for $60, which is a DUT3C JIUHB 0312 stepping
-or-
This XP 2100+ for $77, which is an AIUHB 0301 stepping

The $17 price difference doesn't bother me, I just want whichever one will get me higher clocks at about a 400 - 410 MHz FSB.

both will get you to the effective 400-410 fsb (200-205 mhz).. it's just a matter of the multiplier you use

That's what I assumed, but I'm curious as to which will get higher clocks. Oh, and I know the difference between the actual MHz and the effective fsb, but I think it's funny that you do the same thing I do a lot with RAM. I list both frequencies to check for nooB's that don't realize there's a difference. You never know...

BTW, with an 8RDA+, will I be able to adjust to any multiplier with either proc? At {H}OCP's forums, somebody's telling me that I can only see lower multipliers with the 1700+ (12.5 and below) and higher multipliers with the 2100+ (13 and above). Is that true?

If you're looking for higher FSB's... look at my rig... 221 mhz FSB with my Barton

I'm actually more looking for highest clock, as highest acheivable FSB will be determined by my mobo (8RDA+ with C1 stepping NB).

You cut your 3rd L12 bridge, yes?

No, I took it out of the box, put AS3 on it, put my SK-7 on it, and it works fine =)

As far as the topic, I would think both CPU's would do whatever Bus speed you wanted... but as far as which chip would yeild the Higher "CLOCK" speed, I would have to "think" the 2100+ would? Just a guess.

I just got my 2100+b in this evening... I've got it running at 175x12 = 2.1GHz with 1.65volts. I don't want to push my FSB any farther because my ram kinda sucks... it's running at 7,3,3,2.5 at this speed. I'm going to get some CAS2 PC3200 soon and put this memory in my wifes computer as soon as I get another NF2 board (she's currently running KT133A YUK!)

I may try 183x12 tomorrow.... but right now, I'm sitting at 50c CPU Temp. I have an "OLD" copper cooler that's not very big, so to go any higher I think I need a more modern Cooler. Any recommendations???

Thanks

Thermalright SK-7 if you are on a budget or a SLK-800 for a little bit more money. Both work well.

I'm not on a "budget", I just don't like to spend "un-necessary" cash. If you know what I mean. I'll spend $$$$ if I have to... but ONLY.

Thanks. I'll look into them both and decide. I'll probably go with the better cooler.

I'm running at 166x13.5 right now @ 1.7 volts (2.25GHz). Seems to be running fine, but temp is 52c. I'd like to get it down to the low 40's. This cooler I got is from back when t-birds "first came out", so It's kinda old (and small).

Thanks

I'd look at the 900 if you have some money to spend. It's a GREAT HSF, and better yet, you can mount a 92mm fan on it, which will push more air at lower volumes. This means BETTER cooling at LESS noise.

Somebody's shorts are in a knot =)

 

[Shimmishim]

but you're running async and not 1:1

if you try 1:1, i bet you it won't work unless you cut your 3rd L12 bridge...

depends on the board. I have a k7n2-L that would only give me the higher multis with my 2100+ until i unlocked the chipNow it only gives me the lower multis. I also have a soltek sitting here burning in right now with a 0312 JUIHB 1700+ in it that has all the multis available in the bios. By the way I am really liking that Soltek board to. wish i could swap it for my MSI.

The 900 seems aweful large... would it fit on my A7N8X for sure? It looks like the HS for me if so.

I have the NF7-S ver1.2 and I can adjust to all mulitipliers

Glad your gettin' some Golden Flame lovin' :beer:

As to the thread topic, IMO the 2100+ and 1700+ seem to have about the same max potential and I think the reason you see more reports of the 1700+ hitting high clockspeeds is because there have been so many sold
