xp2500 barton vs. xp2400 t-bred

CDsDontBurn

The bartons have a 512k L2 cache, and a 333FSB. I'm aware that even if the multiplier is locked, i could still raise the FSB. Now i'm debating between a barton 2500 and and another thouroughbred 2400 (for another system). The price difference is about $5-$10 depending where i would get it from. What i'm planning on doing is have the 2500 run at 3200 out of the box, or the 2400 at 2700 depending on which one i get. Now how high can i run the FSB of the barton even if the multiplier is locked? I have heard 400, is that true? And what is the multiplier of the barton 2500 set at? I've heard multiplier is at 11 stock, and those w/the locked multiplier just bump up the FSB to 400 and Presto! instant 3200+

Right now i'm favoring the barton, but i want some extra 411 just to be more certain that is what i want.

With AMD having locking the multipliers, i've heard AMD being caled GayMD. I'm still holding hope with AMD tho cuz of their new 64bit chips. Sometimes i consider going pentium. The only pentium based chip i have is my old celeron 566 from my old hp that now sits in the corner. My other 3 systems are all AMD (1.2 t-bird, xp1900+, and xp2400+ @xp2800+). Not being able to comfortably work in my hp is what brought me to building my own systems, and took me to the power of AMD.

Try to get the Mobile 2500 Barton. Costs a little bit more than the regular 2500 barton but the multiplier is unlocked and it has been known to OC to 2.7 on air easy.

Or...you could get an Nforce 2 mobo which unlocks all AMD Barton chips if I'm not mistaken.

I have an nForce 2 board and a XP2800+ Barton, and the Multipliers are NOT locked.

I still overclock only using the FSB changes, as all that Multiplier stuff is too...much of a pain in the
arse to mess with. I'm not a huge O'clocker though...

No_Style

After a certain week, Bartons became locked despite NForce2 ...That's what I've heard. But, yeah go with ZeroDamage's idea if you can.

Where can i get a mobile barton 2500? The places i go to only have the desktop version of the barton as far as i know. I myself have an nForce 2 board (Epox 8rda+). But i've heard from some of my friends and reviews online that w/an 11 multiplier and raising the FSB to 400 you get instant barton 3200. BTW, what is the multiplier set at of a 2500 out of the box?

zerodamage

The multi is 11 out of the box for the Barton 2500. I have the same exact board and as long as you have the Crush18 or Rev 1.1 of the board, you can hit 400 fsb easy.

CDsDontBurn

I don't know if i have the Crush18 or Rev 1.1 of my MoBo. Where would i be able to find the version of my MoBo? I think I have one of those two versions cuz in my BIOS i can set up my FSB all the way upto 200.

I have 1x512 CorsairXMS 3200 stick of memory in my system. Is it recomended that i get another stick of memory to run dual channel, or can i run it w/just my one stick of memory?

dj_stick

i bought a barton 2500 and set the FSB to 400 as soon as i got it, and it has been running fine, if a little hot for about 3 months now

I finally bought my chip. I decided on the barton 2500. Well, despite my board being nForce 2 board (Epox 8rda+), it didn't unlock the multiplier . As for going w/the 2500 mobile, i checked out some prices, and it was a bit too pricey for my budget. It was $99 before taxes and shipping. But hey, 3200 out of the box aint all that bad, considering i went from 2400 . I just wish it wasn't locked so i could play around w/the multipliers and see what i could max my chip out at. Oh well.

BTW, my chip as AQYHA

This whole thing with AMD locking multiplers is a bad move. certainly it was a major reason alot of people bought them over INTEL (apart from the cost obviously).

G@MeBoY

nForce2 board that unlocks multipliers What are you guys here on DH telling people ? Sorry Pac-Man man, If I came here earlier I would told you that no board is unlocking multipliers ! What BMG Cya had in mind was probablly that Abit NF7 boards have 5-bit mltiplier controller so they unlock multipliers that are below or above thoese AMD specified , for instance, XP's over 2600 have multiplier minimum of 12.5 so you can not change it below 12.5 except if you have a 5-bit multiplier controler on mobo which seeks for "a pair" multiplier and alows it to be set, for instance, "a pair" of multiplier 12 is 6 so mobo gives you the choice if has 5-bit....bla bla as far as for locking CPU's, locking started on week 39 and all after 39 ARE locked (CP id ribbon can tell you many things and among them is week, it is the last number in ribbon, says like 0339 firs 03 means it's made in 2003 and second 39 means it's made in week 39 and it means LOCKED) before week 39 CPU's are UNLOCKED (some exceptions) Also barton 2500 can be 266 (acctually remarked barton called XP with barton core ) and 333 FSB (if BOX not OEM) and can also be worse for OC (OC also means "just" increasing the FSB) than XP 1700+ . For instance, my XP2000 can run at 10x240FSB or 11@220 or...(same speeds) where my friends barton 2500 cant run at even 200FSB because multiplier is locked, CPU is OEM 333, and 400 is just way too much for it (11x200=2200mhz) even with 2.0V vcore. If you ask me (and some other people) AMD started locking older CPU's so it could sell more Athlon 64, and other 64bit CPU's. I also suppose that AMD didnt like people giving 70$ for XP2000+ and making it 11x200FSB and not buying XP3200 and Barton's for 200$ (made from same core and rated higher FSB by factory settings) . What do you think Zardon ?

PS. Pac-Man, you could probably make xp2400 that you had, into xp3200 easier than this barton, but, since you bought it, you still can play with it, just increase FSB step by step. Your memory can be a bottle neck here, so do this:
1: FIRST OF ALL in bios where all cpu settings are, set interface from OPTIMAL to AGGRESIVE , this dissables CPU interface controler, put simply, it does not prevent you to OC how you want, when enabled, if you go to high it will reset CPU values even if setting you made is safe and possible.
2: Maybe you know, maybe not, here it is anyway, when you screw something up and cant get computer to post, restart it by button and amidiatly after press/hold "insert" on keyboard.This returns defaults.
3: set your memory FSB ratio timing to 50% . By doing this, you eliminate "memory cant handle speed" problem. You want to know how far CPU goes
4: enable shutdown for high CPU temperature. Set it to 65 or 70.
5: To make CPU go higher when you reached the setting when comp post doesent happen, you have to increase vcore (CPU) voltage. You can safley set it 1.8V immediatly, but for highest possible clocks (upper boundaries of unfortunate CPU) you need 2.2V setting, this I do not recommend without STRONG (at least 360W BRAND NAME (popular)) PSU AND GOOD COOLING (my TT11+ cools 2.2V for about 10 mins, then CPU becomes hot and unstablle). With 1.8 or even 1.9 you wont burn anything, dont worry, AMD just loves that ! and even if it overheats, your mobo will shut down the comp at that 70C you set, and thats safe temp.
6: Figure out your self, this step, and couple of more are EXPERIENCE which comes with lots of fun OC-ing and I dont wont to spoil it for you

cheers, and....err....sorry for the long post, but I think it's a good read for many people here on DH, esspecialy thoese "MB unlocks CPU" and alike members Happy OC-ing to everyone !

I got the 2500 barton over another 2400 for a few reasons.
1. The chances of having the 2400 with a locked multiplier were much higher as to when i got my first 2400. The multiplier locked at 15 woudln't let me overclock it as high as my old 2400 could go (got it to 2.6Ghz).
2. Despite the 2500 having a locked multiplier, i could still raise the FSB too 400 to OC it.
3. The 2500 has a 512k L2 cache where as the 2400 has a 256k L2 cache.

The memory i have is 512Mb Crucial XMS DDR400 Cas Latency 2. I need another 512 stick to run dual channel tho . I don't think it might be the memory that's a bottleneck, but it could be a factor.

I have my system shutdown temp set at 60C. Along w/the 2500 i also upgraded my cooling from TT Volcano 11+ w/standard thermal paste, to artic silver 5, thermalright SLK900A heatsink, and Vantec Tornado 5800rpm fan. This thing keeps my 2500 hella cool (@1.7v dunno yet for 1.75v); 37C idle, 40C load (ran 3Dmark 01/03). My psu is an Antec 450watt.

I had my 2400 @ 2700 (13x166 @ 1.7v) and it was running stable. When i got my 2500 i ran it at 3200 out of the box (11x200 @ 1.7v). I've had it for about a week already, and i raised the voltage to 1.75 last night because there IE6 kept crashing to desktop. Windows (winXP sp1) hasn't given me any errors yet except for the crashing of IE6. Hopefully the increased voltage will fix that. I haven't gotten around to re-installing windows, which i should do somewhat soonish; maybe that would fix the crashing of IE6. I haven't played any games so i don't know how that will fly on my 2500.

before i bought the parts for my new system, i was considering going intel, but decided against it because of the price, and because i would have needed to buy a new MoBo along w/the processor.

G@MeBoY

my XP 2000+ goes 2300MHz with TT11+ at 3500rpm at 10x230FSB for every day use. My XP is unlocked so it's worth more than any barton that's locked out there. 512 kb cache doesent give any increase in speed. This has been found by meny benchmarks over the net, in some cases it even slows down system, this is unnoticible. system increse is only with HDD's but it's also unnoticible. What I am saying is that you should not change your XP2400 for barton 2500....

BWX

When I get my SLK900 in a few days I'm gonna see what this puppy will really do- I got it completely stable at 2.25+ ghz @ 1.67v (that was with the Corsair XMS @ 2-3-3-6) ~An a GENERIC 350watt PSU (dual PSU), and a generic copper cooler with a 70mm fan.

Now I have an Antec 550 true control, OCZ platinum special edition 3200 (2-2-2-5) and when I get my SLK 900 i a couple day's I'll be set to hit 2.4+ ghz or more for everyday use. Hopefully with a 225+ FSB-- Can't wait!

i got a week 48 @2.6ghz 13x200 1.75v Been folding/gameing for a day STABLE. im running the cpu on a corsair Hyrdo-cool 200 Water system. Its not much better then a slk-900 w/ delta fan.

got it ten min ago,put it in and bam 2400 mhz no prob.running very stable 12x200 at 36 c air cooled 1.675 v,3dmark 14000 best ever
love this thing,alright let me go bump it up a little more see ya!!!!

HannibalTheCannibal,3/4/2004 4:05:16 PM

Well, I made the switch from my "locked" 2500+, to one of these. NOT disappointed at all. I set it at 12.5x200 @ 1.8 vcore for starters NO PROBLEMS!!!. I am now at 12x210 (there abouts) 2550Mhz. CPU temps from 37 (browsing) to 43 (gaming)
I hit my alltime 3dmark01 high score of 19670!!!!
FYI These CPU's are no longer manufactured, get one while you can. I received my order quickly (3business days). If you have never ordered from newegg, you should give em a try. They have best customer support than that of any other online retailer.

I bought this cpu on tues and recieved it on wed. Right when i popped it in i ramped the fsb up to 400MHz and the multi to 12.5x for a cpu speed of 2500MHz @ 1.70v. I had a barton 2500+ that would hit 2.4GHz at 1.9v this is amazing WOW! i love it. I could see this replacing the 1700+ tbred B and the 2500+ barton as AMDs top overclockers. the max i hit with my TT Silent Boost + Tornado fan is 2.7GHz @ 1.93v stable. 216x12.5.

I'm using an older board, namely ABITs NV7-133R. Its a 266 bus only with minor front side bus overclocking. I wanted to get one last cpu upgrade to tide me over until the socket939 Athlon64s come out.

Unfortunately the chip would only work with a 6x multiplier even though I tried all of the bioses that support 2600+ processors. That works out to 800mhz on a 266 bus (6x133). It was displayed as an "Unrecognized 800mhz CPU" by my bios. I spent a couple days on the forums and found out about "pin-mods" at ocinside.de.

Well, after all that stuff I got the pin mod to work and I'm running full speed now. Great performance from this CPU. It's replacing a Palomino 2100+ and actually makes a noticeable difference even in regular usage. Hooray for 400 more MHZ and 256k more cache!

Except for that inconvenience this is a great chip and of course NewEgg is the only place to buy from. Got the cpu 1 day early

Recieved IQYHA 0401...fairly new & with tamper resistant packaging. Got to try it in a kt7a-raid v1.0! Does very well at 12.5x124 @ 1.545v & 37c (no load) or 41c (air) w/prime95 all night...(+4c under load!!!). (It's not even supposed to work). Tried a A9 mobile rom.by (named r10.bin) patched bios...recognized mobile athlon 4 but didn't work for p-state changes. The default (read as desktop "recognized") multiplier is ...off. User defined is the way to go=no Auto. Default boot 600,850,1250 depending on how my bios' felt when cmos cleared (at least it's postable) . Max p-state mult. set at 15. One curious thing, the reset problem that was talked about with athlon xp and kt7 never reared its ugly head with my Palomino but with Barton...It reared its ugly head so I forced to flash a b4 (v1.3) bios. Cured the problem...but the CPU wasn't recognized so I tried biospatcher against the b4 bios and now it reads as Athlon XP (Bartlet). ***This bios is completely stable in my 1.0 board WITH THIS CHIP*** >13x multiplier for me would mean playing with 8X high or 4X low and the funky l3 code or taking out mobile or....for the real overclockers out there. I'm not ready yet; my palomino is sliced & diced. Hopefully the real board this chip is going to call home supports p-state changes (or 5bit multiplier if that even getcha >12.5 mult... maybe I should be looking at FSB but then RAM, etc)...or a dually. This is only very marginal improvement over my palomino for the price. [PS: the GigaByte dually don't do p-state.] To be honest the 800 bus P4 2.8ghz with 1meg cache and HYPERTHREADING!!! for $200 (...thanks egghead) looks so good. My last three have been AMD...the tide may turn.

Talibano,3/2/2004 2:56:07 AM

Thats right 1.9vcore that my mobo puts out ain't enough!!
In windows running 2.7ghz @ 1.9vcore not stable for gamming.
So i need a mobo with more then 1.9vcore , and yea i'm on AIR
SLK-800 TT-S2 , but soon to upgrade the heatsink and fan also to a better ThermalRight.
Intel WHO? Intel WHAT? LOL

cachipop,2/24/2004 5:08:22 PM

Just came in today and put it on an air cooled computer. Running 2625 Mhz, 1.93 Vcore, stepping IQXFA 0348, 210 FSB X 12.5 !!!
Havent ran Prime95 or Memtest86 however, 'cause I'm going to install it on my water cooled rig. I think it will break 2.7 Ghz. EASY.
It was sooooo easy pushing it to 2625 Mhz (PR 4.2 Ghz) on air cooling alone. Get one of these before they are all sold!
Great delivery and price from Newegg, as always...good job !!!

Red02TA,2/24/2004 4:39:57 PM

This is a great value for the money. I am currently running mine at 2580mhz at 1.875V on an NF7-S 2.0. This chip simply Flies! If you don't want to push it that hard, it was stable at 2500Mhz@1.75 Volts. Amazing in my mind. They are out of stock for now, but if they come back, I would Highly recommend them.

d4m0n,2/20/2004 3:43:58 PM

I ordered a mobile 2500+ and this became available almost immediately after I clicked "submit". I cancelled that order pronto and decided to take a chance on this 2600+ (for $105 - only $7 more than 2500+ at the time).

I'm pleased as punch with this chip. My first barton (an unlocked desktop 2600+) barely did 2.3GHz on 2v. My 2nd one (a locked 2500+) did 2.5GHz on the same 2v. THIS CHIP DOES 2.5GHz ON 1.775v!!! All 3 o/c results were tested Prime95 stable for 24hrs+.

I have nothing but praise for this chip. I wish I'd started with this one. Prices are going up, but I'd buy it again at the current price in a heartbeat.

As usual, NewEgg got it to me early.....FOUR DAYS EARLY. Ordered on 2/18 shipped to my office in SoCal by Express Saver (deliv was sched for 2/23) and got it the VERY NEXT DAY. How do they do it?!

I am amazed, I live in crappy Yugoslavia and I don think I can find one here I dont even have a Visa card or somthin' because they wont give it to us [CRYING] buhaa haaa... [/CRYING] This things go 2.0GHz @ 1.45V !!! I think intel should beware of this one ! Just imagine....[sunny day, grassfield] AMD ATHLON FX53 M O B I L E for 100$ [/shattered grass fields, rain starts, back to reality]

Don't feel too bad- I live in the US, have a credit card, but cannot get one because I just spent about 300 bucks on my rig- so I need to pay some of it off first.... By the time I can get one, I am sure they will be gone...

I still like my Tbred though haven't even begun to push it yet- I got my slk900, but haven't installed it yet- I think tomorrow I'm gonna.
