What AMD XP Processor?

[Wally Simmonds]

Im looking to get an XP 1800+ in the next couple of weeks. They are reasonably cheap, about $250 or something like that. My question is, should I get this chip or should I go for something a bit more gruntier? The XP 1900+ is about $315 and the 2000+ is about $375. I will have a geforce 4 ti 4200 to go with it too....and eventually this chip will be overclocked to buggery when I gather the courage. What would be the better deal?

Thanks

my xp1700 doz 1740Mhz..
its an AGOGA-Y core cpu... so any XP with that stepping should be able do do at least that speed... id go with the XP1800 if i were you... good value for money

[KingJackal]

Let's see...
( comparisons relative to the 1800+ )

XP1800+
1533mhz, $250 ish

XP1900+
1600mhz, $315 ish
4.4% more performance, 26% higher price

XP 2000+
1666mhz, $375 ish
8.7% more performance, 50% higher price

Dude - is it really worth it? Turning an XP1800+ into a 2000+ is as simple as going into your BIOS and changing the multiplier from an 11.5 to a 12.5. If you get the right core and heatsink - it won't even break a sweat doing that.

Forget what speed stepping the CPU has printed on it's little box - that's all just marketing. Search out a CPU with a good stepping ( AGOGA is a good one ).

[Wally Simmonds]

And what, pray, is AGOGA? Is that the chip revision or something?

[Glycerine]

its a batch number (will be printed on top of the CPU core)... u get good batches and bad ones.. AGOGA was a very good batch for overclocking.. bout 50-100Mhz higher overclock then other batches

[Wally Simmonds]

Is it the same with the durons? I have a duron 1ghz that doesnt seem to overclock that well, but Im putting that down to the standard heatsink/fan....when I get my volcano 7 back it should be better.

[Glycerine]

yeh its the same with all cpus

Don't forget he'll have to unlock that little mofo before he can change the multiplier........

Wally: Make sure you have some good OC'ing RAM (Samsung TCB3, Corsair XMS PC2700, etc) and unlock the CPU - that way you will be able to have the FSB @ 185Mhz and you could set the multiplier to 9.5x - resulting in the end CPU speed of 1758MHz. A high FSB will get you better overall system performance than just increasing the multiplier.
Overclocking, will of course, depend on the motherboard used........

[Wally Simmonds]

Okay where could I suss out these AGOGA's? Im looking at the purchase 2 weeks from tomorrow. (I get paid fortnightly, unfortunately)

[SilverPriest]

Give ole John (john@stylespc.com) @ StylesPC (www.stylespc.com) a bell...
He should be able to help ya out

[I.R]

AGOIA is good as well..... That's the last stepping of the 0.18 process....... highest "official" speed of that steeping is 2200+ ;)
Don't know about the highest "official" AGOGA :o

[Stove]

If I read the AMD development pathways correctly, the present XP core will soon be phased out to leave all the lower XP cpus with speed-limited T-breds, am I right? If so wouldn't it be a good idea to wait a little for a T-bred 1800? That bugger'd overclock like a demon

get a Intel Pentium 4 1.6Ghz Northwood Socket CPU + Fan Retail Boxed 3 Years $365 instead from pp.co.nz

for the simple fact that these cpus pwn :D

Umm, nice statement there kaz. :rolleyes: He already has a Socket462 mobo, and the XP1800+ is $100 less than the 1.6GHz Northwood.

LOL.

I believe the term is:

SHUT - DOWN
:D

Shoo, shoo evil Intel w[H]0r3z :D :p

[Binky Stunt Cat]

or, for the lesser beings among us, that means "pwned"

Fairly large base of info on whats good batch for clocking can be found here: http://overclockers.cssftware.com/cpudb/index.cfm

just select the cpu you want to look at, then take a look @ the batch of the best clockers. :)

For example, AGKGA-Y batch for a XP1800 got to 2250mhz, using peltier cooling.

Plenty of batch's made 1800mhz

AGOGA are two steppings behind. AGOIA is the current one, AROIA is the released one.

I suggest an XP1700 AGOIA "Y" or "4" or "9". Week 2,4,6,7,9,12 all yield about 1850mhz aircooled, weeks 16 and 22 yield about 1900 aircooled.

I have done 2004mhz watercooled @ 1.95v with minimal problems, and have obtained benchmarks @ 2078mhz using iced water.

Can you elaborate on 'minimal problems' please? Were the problems stability issues?

Power Supply problems. My Top Power 400watt is dying in the ass. I have a replacement 550watt Antec on the way, and should have it tomorrow night.

Damn Bravo, what the hell are you running??!!

Am i right by saying AROIAs should OC better than AGOIAs?

Its generally assumed the lastest stepping is the best, which is semi-true. Later steppings are simply refinements on earlier steppings (cooler operation, faster cores, lower voltage cores etc..).

The week in most cases is more important then the stepping, as is the production line (third line, "Y" "9" "4" "K" "R"). I have found weeks 4,6,7 from the "4" production line, with the AGOIA stepping yield better results then processors from the same week, but different production lines.

Usually a combination of things makes the processor. I try to watch what people are testing, and pay close attention to what they are running :)

Nice FSB!

*drool*

[Volodkovich]

bravo - arent the "Y" processors generally the best at overclocking?

Its assumed they are for the simple reason they were the best AXIA overclockers.

Its not the case however, the week, and the stepping play more part then the production line.

[Volodkovich]

So what is the best week and production line for AROIA's? The reason im asking this is im about to buy a AXP

[mird-OC]

find a tbred :)

they're around... ;)

[Volodkovich]

yes :) for about $600, which is like half of my budget

[Gh0s7 L3mUr]

Bravo: have you thought about bringing out a "list" with this stepping/week/production line info?
It info seems a lot more informative than Overclocker.com's database.

[Bravo]

Not really.

:)

Havent tried an AROIA. The AGOIA's are by choice the better processor (running cooler, and clocking higher).

[Volodkovich]

bravo - lol, axp questions again :)
how high do ut think an AGOIA "4" week 20 will do? is this a good week? Also, do AXP's work on the AMD 761 chipset?

I havent tried a week 20 processor :)

Should do fine. KT133a and up chipsets tend to have no problems using a palomino.

[Wally Simmonds]

Are the AGKGA AMD XP 1800+'s any good?
I just got one today and I would like to know if its gonna burn well

[Stove]

Haven't got any personal experience myself, but from a quick Google (http://www.google.co.nz/search?hl=en&ie=UTF-8&oe=UTF-8&q=Athlon+AGKGA+overclock) search, it seems that its at least as good as the AGOGA stepping. This (http://www.hw-a.it/eng.shtml) italian site has a fair few overclocks listed, and AGKGA overclocks are pretty common, and pretty good :) (stable over 1800MHz, for some lucky buggers)

[Wally Simmonds]

Are these 'new' xp 1800s thoroughbreds or palaminos? How can you tell? I know they released the xp 2200+ as a thoroughbred but I thought all the slower chips were getting released @ the .13 micron process as well
Please correct me if Im wrong.

[Grrr!!]

All Athlon XP processors will switch to the 13 Micron process.
