New barton @ 2.2ghz already

speeduk · Aug 4, 2003

Just got my new 2500. A little disappointed in the colour, similar to my 2100, but im at 2.2ghz on stock voltages already, been running prime95 for 10 minutes and so far so good. This is looking like a nice chip to reach 2.4-2-6ghz.
Temps in the mid 40's but its very hot again here and i left the window shut lol so its like a greenhouse in here.

Found the limit of the chip. It doesnt seem to like doing much over 2376mhz @ 1.87 volts for some reason, probably due to the average quality of the chip so i've settled for 2.3ghz @ 1.85V with turbo mode on and it wipes my 1700 @ 2.4ghz clean.

Heres a summary of my Athlon overclocking experience:

2100 JIUHB 0308 purple/grey colour core maxed out at 2.3ghz 1.9v and ran upto 56C full load. Settled for 2.24 @ 1.875V 44 idle 50 load

1700 JIUHB 0324 grey core would do over 2.4ghz but ran over 60C. Settled for 2.3ghz @ 1.85V 49 idle 55 load

2500 AQXEA 0327 grey/purple core will do 2.4ghz on high voltages. Settled for 2.3ghz @ 1.85 47 idle 52 load.

And heres the performance difference:

2100 @ 2.24ghz/195mhz fsb 16000 3dmarks 2001se
1700 @ 2.29ghz/199mhz fsb 16130 3dmarks
2500 @ 2.29ghz/199mhz fsb 16290 3dmarks

With my 9700pro running @ 351/324 I got a new high score of 16890 compared to the 1700 running at 2.33ghz on 204mhz fsb scoring only 16794.

After all the testing ive done, I can see why AMD released the barton. Its faster, cooler and well priced. Right now I have a 2.3ghz barton and i'm well chuffed, especially as the 2.2 costs £360 and this only cost me £70....

I think you were right. Being able to do 2.3 Ghz at ~1.85 volt seems to point to a 2.4-2.6 ghz capability.

You just need water cooling to do it.

Congrats on all of your overclocks but was it worth it, going through three processors, that is? I mean, you started with a 2.23 ghz processor and ended with a 2.3 Ghz one.

I still think Tbred B XP1700+ was the best bargain of all time, especially if one had a modern mobo. No mods needed, decent overclocks, and cheap, cheap, cheap.

Too bad XP1700+ is in short supply now, no longer being manufactured. $42 USD (about 26 GBP) was nice while it lasted).

Not sure what I would choose now. Tbred XP2100+ is 19% cheaper than XP2500+ here in the USA, $61 (38 GBP) delivered vs $88 (55 GBP). However, with a modern mobo you have to do a mod to get access to the lower multipliers while you don't with Barton XP2500+. On the other hand, there are still a few places carrying Tbred B XP1700+. The prices are going up, though. Now at $51 delivered (about 32 GBP)

I'm curious what prices Thorton (sp?) will carry and if the multipliers will still be unlocked.

It was worth the experience. I enjoyed every bit of it. Especially when I remember hitting 2.2ghz for the first time, I was so excited. Having upgraded from a 1700 palomino and a 266mhz board, these new chips and nforce 2 boards are an excellent and cheap upgrade path for those willing to take a small risk.

If I had watercooling, the 1700 would have hit 2476mhz on maybe 2 volts. Thats a lot of voltage for a 1.5v chip. Temperatures arn't really the problem, its the amount of voltage that I dont like shoving through a chip to get an extra 50 or 100mhz out of it. The max I will try is 1.925 once the AS3 has settled on this chip.

I tried 2389mhz on 1.9v and it was stable but going from 1.8 volts for an extra 100mhz doesnt seem worth it to me.

My board has an option to overclock the link between the cpu and fsb, dont know exactly what it does, but when you enable it, you need to up the vcore by .05 and make sure memory timings arnt too low or up the voltage. This gives the performance of an extra 150mhz cpu speed. Thats why i'm staying at 2.3ghz with this on at 1.85 volts. Its faster than 2.4ghz at the same fsb. In order to do 2.4ghz with this enabled, it will need probably 1.98 volts, and thats a bit too much for me....

A few notes on multiplier unlocking. My board unlocks all the multi's for my barton and did the same for the 2100. I ran at everything from 16x136 when i had 133mhz memory to 11.5x195.

Also about the enhanced cpu mode, the tbreds needed too much voltage to remain stable with this enabled, but with the barton its 100% stable and very fast. Just by enabling this I get an extra 3fps in the lobby test in 3dmark 2001se, not taking into account the extra cache on the barton. So even though Im at the same speed (2.3ghz), im actually at a comparable speed of 2.5ghz or higher. This is why I will be getting another barton later in the year when I can guarentee a grey core and do 2.6ghz with this mode enabled and have in effect a tbred @ 2.8ghz.... Im drooling already hehe...

Bummer it wouldn't go very high.. but still a nice OC. And as long as you liked doing it it doesn't matter how high it is (well... it still does but not much

).

As soons as this heat-wave is over in Europe I'm going to see how high my CPU can go... I might have to unlock it for the higher range though as I don't know how high I can get my KT333 chipset stable.

Yeah the heats a bummer for overclocking. Typical, when I got my 1700 it was the hottest day of the year. I get my 2500 and its ever warmer lol. 2.3ghz is what I was aiming for really and anything higher just a bonus. The fact that I can enable agressive interface too at only 1.85 volts is excellent and just as good as it overclocking to 2.4-2.5ghz...

Which board unlocks all the multipliers? I heard the Abit nForce2 but no one ever confirmed this for me.

Your Tbred B XP1700+ was obviously much better than mine. 1.8 volt gets me to 2.1 ghz but I need 2.15 volt to reach 2.25-2.267 ghz range. My XP1700+ is a JIUHB, 0302, DUT3C.

It might go higher but I cut my testing short when temps exceeded 60 degrees C. There isn't that much more performance to be had on this old KT133A mobo, anyway. 2.1 ghz is good enough besides I don't want to invest in water cooling.

TheMASK · Aug 4, 2003

thats about as much as i cud take my 1700+ t-bred B DUT3C.
2220MHZ at 1.95V is the max i cud get out of it. now i am running it at 2088MHz at 1.7V.

I only write to get more posts...

phsstpok · Aug 5, 2003

Yeah, I was surprised at how quickly I ran into a "brick wall".

No problems getting to 2.1 Ghz with 1.75 volt but to go any higher lots more voltage was required. Somewhere around 2.2 ghz I needed about 1.95 volt and as I mentioned 2.25 ghz and higher needs at least 2.15 volts. I never tried 2.25 volt. In fact, 2.15 was a mistake made when I misplaced a jumper on my mobo.

My mobo has incremental jumpers which allow me to go above the max BIOS setting of 1.85 volt. I was trying to set +0.2 but set +0.3 instead.

2.15 volt is a bit much for a Tbred B core with only air cooling.

One thing that is strange. Over the months I gradually have needed more and more Vcore to run stable at 2.1 ghz. First I increased to 1.775 volt and now 1.8 volt.

I use the epox 8RDA3+ board. I got it just for overclocking, as in the reviews they stated it unlocked all multipliers. What colour was the core on your 1700? My bet is it was just an average chip with a more purple look to it. Ive seen a few pictures of peoples chips that reach 2.2ghz on stock voltage and 2.5ghz at 1.75 volts. They are pure grey, not a hint of purple in them.

When I ordered my 2500, they had been in stock over a week already, so all the best ones will have been sold, because their main customers are enthusiasts.

The thing is now i've reached such high scores for an AMD system in benchies, I wont accept anything less lol. Theres no doubt about it though, a good quality barton chip will get you 2.5ghz easily.

my case exactly!!!

I can do 2050MHz with as low as 1.65V. But to go to 2175MHz, i need atleast 1.9V. Just exponential increase.

The max Vcore i can do on my A7V8X is 2.05V. Anyways, i did that once and at 2220MHz, once the full load temp shot upto 68-69C.

I didn't do it, nobody saw me do it, you can't prove it

svol · Aug 5, 2003

I even want to run it at 2 V if that is needed to push the max out of it... watercooling all the way.

Anyone an idea how high the KT333 chipset FSB can get before the chipset starts crapping out... if it depends on cooling then I don't have problems (mobo is also watercooled).

speeduk · Aug 5, 2003

Who made your board svol? Epox,MSI and Abit's kt333 boards do 200mhz or there abouts. Asus and aopen do around about 150-160mhz stable.

It's an Epox 8K5A2+ (I love Epox... all the settings you will ever need right there in the BIOS).

200 MHz FSB... that would be awsome, then I can use my PC3200 RAM to its full potential.

I'm going to try it as soon as this damned heat leaves the country.

TheMask,

Which week is your core?

We seem to have the same overclock limit but yours Tbred will run 2.1 ghz at 1.7 volt (I think you said) while mine needs 1.8 volt.

System is running hot today. It's a warm summer day and it's reached 80 degrees (about 27 C) here in the basement. Idle is now 43-44 degrees. Normally that's what I would see at load.

SpeedUK,

I didn't really take note of the core color but I thought it was blue-ish. I didn't have a choice of cores from Newegg.com. In fact, I was lucky that it wasn't a Tbred A. Newegg was only guaranteeing a Tbred for a ridiculously low price at the time. (I think it was $51 USD delivered back in February).

TheMASK · Aug 5, 2003

Nope. Mine does about 2050MHz on 1.7V. But if i am doing 2.1Ghz, it needs no less than 1.85V and 2.2GHz at no less than 1.95V. Even if i go as high as 2.05V, i cant go over 2220MHz, at least not on my A7V8X.

The core is partly grey(with a tinge of green) and partly pink(purple). And its of the 0310 batch.

I didn't do it, nobody saw me do it, you can't prove it

phsstpok · Aug 6, 2003

Hmmm, I thought all XP1700+ and XP1800+ from week 07 and later were 1.5 volt procs but yours is a DUT3C.

That's a bit of a bummer because the DLT3Cs seem to overclock better.

I recently purchased a barton 2500 as well. I OC'ed it to 2.1ghz and I want to go higher. I'm using the new asus deluxe mobo but my ram is old and I think that is the problem. It's DDR333 PC2100. What I'm thinking is that I need DDR400 3200+ ram in order to OC, since I'll probably have to change my FSB to 400 instead of 333 to get more out of it. Any suggestions on this? This is my first OC so I'm not sure how to get the best performance with that I have. What ram did you use for your OC and are you having any problems cooling the core with the increased voltage?

pIII_Man · Aug 6, 2003

Yoda...you seem to have drifted to the dark side!

pc2100 ddr333 WTF?
ddr 400 is always pc3200
DDR 333 is always pc2700
DDR 266 is always pc2100

the pcXXXX number stands for the bandwith of the mem

bandwith is found by

ddr speed x 8 = bandwith

example of ddr 400 ram

400 x 8 = 3200

tada!

If i put my k6 in a Ferrari it would be faster than your your pentium 4 or Athlon XP :tongue:

speeduk · Aug 6, 2003

That board doesn't have the 1/6 divider, so I think a realistic overclock would be 180-190mhz without making the pci/agp run over 40/80mhz. Having said that, heres what tbreak said "Using an unlocked Athlon XP, we were able to take the FSB as high as 201MHz FSB with RAM running at 2.90V"

Hi Yoda.
Im using Twinmos 3200 memory. It will run upto 202mhz @ cas2 on 2.8 volts and runs over 210mhz at cas 2.5. I prefer lower latency as it gives better real world performance.

Cooling an overclocked barton isn't as bad as cooling a 1700 at the same speed/voltage. My tbred 1700 running at 2.3ghz/1.8 volts would idle at about 47-49C and run upto 53C load. My barton at 2323mhz/1.84 volts is idling at 47C right now and goes up to about 52C after prime 95. It is still hot here though. If your barton will overclock to 2.2ghz on stock voltage and thats all you want from it, your current cooling may be enough. Higher voltages will need a good copper cooler and lots of airflow or even watercooling.

Im impressed that its only reaching 52-53C in 30C ambient room temp. When it gets back to normal (below 20) I will have ub0r temps

Well I tried 200 MHz and the northbridge can handle it perfect... it passes Memtest86 without a glitch.

But yeah I'm kinda worried to run it at 40Mhz PCI (I don't care about AGP... I got a GeForce2 MX running at 89 Mhz and the Radeon 9700Pro should be able to do the same).

Well I will continue testing when the heat is gone.

Nice one m8. BTW my barton has been running with a 7% memory bandwidth defecit compared to the 1700. Took the jumper off instead of having it on 166-200 (cures a lot of barton related probs on my mobo) and got the latest bios. Now I get 16300 @ 2.3ghz WITHOUT enhanced mode enabled. Now the barton is working as it should be, I did expect a bit more out of it than I got, now its running as fast as it should and im VERY pleased, especially as now I have the latest bios/drivers and took that jumper off, I may get the FSB to go higher than before
