Current AMD XP of choice?

Alistair · Post by **Alistair** » Fri May 30, 2003 4:35 pm

A popular topic I'd like to follow up on after examining these threads:

Coolest AMD CPU & Athlon XP vs. MP and the AMD spreadsheet that stsmytherie posted: http://www.mishu.com/AthlonXPspecs.zip

Situation: Currently running a 2000+ XP Palamino that is a bitch to cool. I have an Thermalright SK-7 & 80mm on it with good airflow through the case (making it too loud). It gets right up to 70c easily. I've got to get this chip out of there.

I upgrade (pass on) my chip all the time and never spend much on them. I buy lower end chips on the way out at bargain prices. I usually build with 1800's and they suit silent pc's very nicely. For some reason I got stuck with this hottie.

The 2400+(B) is at a good price/performace level, only $20 more than an 1800 - but - runs about the same wattage as this 2000+(Palamino) and only a little less voltage. Is it going to run as hot? Do I downgrade (?!) to an 1800, or are there other options for me?

hmmm... I currently have an 1800+ and a gc68 with a sunon tba2 (i know it's loud) at 2.01 ghz it idles 35 deg c for me. and load about 40-41. Case airflow is decent. (i'll post some stock temps if you want them)

If i were you i'd go with the 2500+ barton it $2 more (@ newegg) it has a lower voltage rating in most cases and never a higher one (from what i see).

edit: also usually the lowest class processor of a stepping is cooler then all those in that class. and some in other clases.

Another vote for the 2500 Barton here. I recently upgraded from a 1900 Palamino which ran around 70. Now I have the 2500 with a SLK800, 80 mm fan and I've never seen over 45. It's a cool chip that's cheap

I'm running a 1700+ JIUHB 0312 at 1250mhz @ 1.1vcore, try that for $43 at newegg...but only if u get a B core, some are A's, thats the gamble you take. The barton is probably an excellent choice as well since it has a bigger die first of all (more surface to suck heat off of according to some believers) and runs more instructions per mhz due to the 512k cache. That means less mhz for the same speed, meaning less heat vs performance so the barton is a good choice at the mid $90's for the 2500+ IMO.

A bit off topic, but does anyone know of a way to get the exact CPU you have if you don't want to remove the HS ??

I have a AMD 2000XP+ that came already assembled with a HS and I don't feel like ripping it off.

use cpu-z or wcpu id or any other cpu stat program.

Alistair: I dont know why your temps are that high, mine never goes over 42c. Try underclocking the BUS to about 100MHz and see if that does it.

Everyone: My chip of choice right now would be a Barton 2800, kick @$$! Only problem is that I dont know if I can spend the money, it's supposed to run as cool as my current XP 1700 Palomino.

I saw this guy on Ebay who mods Barton 2500s into Barton 2800 and also turns them into MPs! And he tests them to make sure they work in MP mode, all for only $130!

athlon anyone can madd an athlon xp (t-bred or barton) rather easiy into an MP jut google it. All you need is some conductive ink.

You have a 2000+ Palamino that runs at 42c?

the 2800 is almost double the price of the 2500 - in a few months it will be half that - why waste the money.

alistar jsut go for the 2500+ you won't be disapointed.

Thanks for the advice, it seems its a good option and hadn't considered it. But, looks like my usual supplier are already out of stock: "discontinued". I'll have to do a little searching around for someone else with a few of these left, blowing them out at good prices of course.

My canadian friend shops at ncix.com

here is the barton link:
http://www.ncix.com/productdetail.php?sku=9132 (i really don't know if that's a good price but if 2 Canadian dollars = 1 USD that's a great deal.)

Last time I checked, "Vancouver, BC Canada" is in Canada.

And so are a lot of the board members here, so you'll probably get called for your comment about our forested friends in the north. Although I agree, not having access to newegg.com seems like a travesty.

@Alistair: I'm not sure how your CPU temps could be going so high. I have an SK-7 on each of my two XP1600+ Palominos, and even though the case is exhausted by two 18cfm NMB fans (the same ones on the heatsinks), the idle CPU temperatures reported by my Tyan Tiger MP hover below 50C, and they don't reach 60 even when folding. And that's with bad airflow redirection. I think the Tiger reads from the chip diode, so those temperatures should be reasonably accurate.

How can mail-order be considered "good access"? I'd rather walk a few blocks to my local shop. Anything they don't have I can order for next day pickup. Any problem or I don't like it - I walk back to the store. Pretty simple. In mail-order-world thats a couple weeks and a lot of shipping costs better served as profit for a hard working small business.

Amazing how people prefer supporting huge multi-nationals who undercut, monopolize and intimidate little shops out of business, destroying communities, replacing them with malls and warehouse outlets. Seems that is the American national sport.

Alistair, rename this thread to "Bash American Computer Retailers".

Im gonna get me a Barton 2500 after I buy a Viewsonic VP171B, that LCD is one sweet LCD, 16ms response time and DVI-D for only $499!

When I changed swapped my xp1600+ palomino to a xp1800+ t-bred b, I noticed a significant drop in temperature. Using the same heatsink and fan, I was able to overclock the new processor to 2.1ghz before I had the same load temps as I had with the palomino at stock 1.4ghz! This could be partly due to the stock 1.5v that the new processor uses.

If you are only building a computer to be as silent as possible, I would recomend getting either a xp1700 or xp1800 jiuhb dlt3c processor.

They run with extremly low voltage, and I belive the dificulty would be finding a motherboard that will give low enough voltage... Here's mine at 1.06v and stock speed:

I'm pretty sure it would have run with lower voltage too, had there only been an option to lower it further. I guess you could make a volt mod to lower it further if you are brave enough.

Barton processors are really nice, and I would probably get one of the if I had to get a processor now. They do produce alot more heat then the normal t-breds due to the larger cahce. I think a good heatsink should still take care of it.

It's an MSI board but which one, is that board with CoreCell?

What heatsink are you running? 1,06 volt is really fine, but 40 degrees celsius isn't that cool ...

Bye egghat.

That was with a cooljag heatsink that was not very good. The fan was the most silent 60mm papst you can find, and I'm not even sure if the heatsink was properly seated. I accidently left the fan unplugged, and ran prime for over 5 minutes before it reached 65 degreese and the alarm went off. I think it could just about have run passive with an slk800 and decent airflow in the case...

The motherboard is a MSI K7D dual socket a motherboard, but at that moment it was only running one cpu. It's a bit strange, but to run two cpu's, I'm forced to use 1.5v, even though they both run single at under 1.1v. It undervolts by 0.4v, hence the low voltage... (world record with amd maby?)

I had two cpu's with that stepping, but accidently killed one of them. I replaced it with a TPMW coded one which is not as good. I also have a 1800+ wth the same dlt3c that is'nt quite up to par. Just my luck that the one processor I manage to kill was the best one I ever had!

I'm looking to upgrade from a 1600+ palamino, could I use a 2400+ with a Zalman CNPS6000-Cu? if not whats the fastest CPU I can use in silent mode?

Very unlikely, & not recommended. Your second question is so contingent on other aspects of system cooling / config that it's impossible to answer, but I'd recommend a HS ungrade anyway. See the review of the 6000cu for why. In a word, the clip: if you have it in use for any length of time in a tower-style system, chances are, it has already weakened/loosened and is not applying as much pressure as when it was new. Check CPU temps.

I have now rebuilt my box with a new 2500 Barton. See my results here: http://forums.silentpcreview.com/viewtopic.php?t=5532

thanks for all your suggestions.
