Comment:

I've saved an old athlon XP from the bin (I believe its an 1800+ Palamino) and put it in my old Abit KT7 - this board only supports socket A chips up to 1.3, or 1.4 if I flash BIOS. But I'd be quite happy if I could run this chip at its locked multiplier of 11.5, but at an FSB of 100, rather than 133.

This would still only be 1.15GHz, but still quicker than the 1G it replaces - and it does seem nice and cool :^)
..but it restarts and then fails to detect my HDD from then on. Should underclocking a chip cause this? It will boot again if I leave it off for a while, and the disk seems fine - for 5 minutes then it reboots, and no HDD again.

It did recently trash a fujitsu 20Gb which I took out, believing it had failed. But maybe not, since the stupid thing's failing the new disk too. Faulty mobo?

Cheers, j1mbo

Check the capacitors. The earlier Abit motherboards, the pre-NF7 mothereboards have been known to have faulty capacitors.

Funny you mention that Randy, literally just checked that and they look like new. Got a good example of blown ones here too - the gigabyte board the AthXP came from.

I'm almost sure the abit doesnt support it, but are the old Athlons similar enough to the newer XP to kid the board into using it @100 fsb?

Might pop the old 1G Ath in and see if it finds that disk ok...

Good idea to eliminate one thing at a time.

Insure the heatsink is properly installed and seated each time you change processors.

It found the disk OK with the 1Ghz Ath back in - then failed after 10 minutes.

Going to bung in an old 9Gb HDD I've got, its always been rock solid, so if that fails...is mobo toast?

I did a little digging & your board doesn't support the XP. The KT133 chipset doesn't officially support 133mhz FSB & the BIOS doesn't contain any info pertaining to the XP. The FSB isn't the only difference between the Athlon Tbird & Palomino. I doubt you're gonna get it to run stably.

I had the same problem with my old Asus A7V133-C board when I tried to run an 1800+ Tbred...the board only supported Palomino core XPs but I figured I could make it run anyway. I was wrong.

You had better listen to "Saint Jams" advice or you might just smoke up that cpu or mobo. JMO.

Hello YOYO,
been seeing you in the forums.

I know this is OT, but can you tell me more abt the folding program? I saw the link and did not understand much.
If my CPU can contribute to space science or any development in any way, so it be! The work I do on my PC does not require a 2000+ anyway. But what aby spyware, hacking?
how does this folding work and whose initiative is it?


Good Luck and Happy Computing,

Kailas,

First off there is not any spyware or hacking to it. At least my Spybot S&D,
Ad-Aware, and McAfee don't see anything wrong with it.

It is a program that folds proteins. I know this is a little deep for most to understand. And I for one am not a doctor, scientist, or professor at a college.

All you do is download F&H from Stanford University, then install it. There ia a different type install for each OS. I use Windows XP-Pro, so I downloaded the Graphic Client version of Folding @ Home. After you install it, it drops a little icon down in your systray. It looks like a tiny little red gear sorta thing. You can pretty much control it from there by right clicking it and it will show you such things as configure, status, pause when done, pause work, etc. If you double click the icon, up comes Folding and it's pretty neat to watch it do it's thing. In that window, you will see such things as your status with the current Work Unit that you are currently running. Meaning how long it will take to complete the WU, how many frames your computer can do in a minute, how many frames are in the WU you are currently working on, etc.

Now if this has confused you, it shouldn't. The program does it all by itself. And your computer does the rest. It will ask you when it's time to connect to the internet so your computer can upload the job it has completed and it will automatically upload the new job for your computer to work on after it has received your last job.

The program pushes your processor around 99% continuous. That unless you need to use it for something. It throttles down automatically and never gets in the way at all.

You get points for the work your computer completes and if you join a board like ours it can become fun in that it is kind of competitive if you know what I mean. It's really alot of fun. As a matter of fact, I have become addicted to it.

Getting back to what it's about though, when alot of people work together by allowing their computers to be borrowed by a college, in this case Stanford, for the good of mankind, then it makes me feel alot better about myself. The program folds molecules of Protein into different shapes and forms and configurations. Someone believes that this is a big step toward finding a cure for cancer, alzeimers (sp), mad cow disease, and several others. This week they had a little news come out about some of the findings. I will see if I can find that story and I will show it to you.

Please give it a try. I think you will enjoy doing it. It is a donation though. But I get rewarded just by know the fact that I tried to help someone in need.

I hope Kevin don't throw me off the board for writing all this up. lol! And good luck!

YO

Thanks there YOYO.
Now some incentive for overclocking ha!
PS: if you see my status, am forced to underclock :( ...thats till I buy some thermal paste :)

and dont worry, i dont think Kevin or Justin are that insensitive.

Kailas,

Here it is.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

We have been studying the p53 tumor surpressor and our first results have recently been published. To our knowledge, this is the first peer-reviewed results from a distributed computing project related to cancer. Thanks to the continued support of FAH donors, this is will be just the first of many cancer related works that will come from FAH.

The nature of our results can best be described in our paper. However, here's a brief summary of our results. Roughly half of all known cancers result from mutations in p53. Our first work in the cancer area examines the tetramerization domain of p53. We predict how p53 folds and in doing so, we can predict which amino acid mutations would be relevant. When compared with experiments, our predictions have appeared to agree with experiment and give a new interpretation to existing data.

Thanks to all who have helped make this possible.

Kailas,

You definitely want to put that thermal grease on it if you start folding. It does run the temps up. I run 3 puters 24/7 with no problems.

Take care.

Funny a conversation on folding is here - started folding yesterday, 80 odd work units in 24hrs and I havent touched 40*C yet. Quite happy, even if its not even close to what a new system might do, it all counts.

Had a thought about the Abit/Athlon problem, will fire it up without a HDD attached. Got a copy of MEPIS linux on CD, if it crashes running of a CD then its not the HDD to blame, at least.

ps cheers for the info jam, I noticed a total lack of booting with an FSB of 133/33, thought this would be fine on a chip called the KT133, lol, I was wrong too.

Have put the AthlonXP away for now...any suggestions for good boards and RAM to look out for to bring it back to its full 1800+ glory?

Im using an Asus A7V rev 1.05 classic motherboard, it has the same chipset as your Abit KT7, which both ultilize KT133. Now I'm running it with an unlocked Athlon XP TBRED-B Core 2100+ @ 101x20 @ 1.75v. I ran into quite a few of problems. I can boot at 101x22, 101x23, 101x24, but I bump into Vcore problems.. Eg..

Vcore I set in BIOS Actual Vcore

1.60 1.57
1.65 1.57
1.70 1.67
1.75 1.71
1.80 1.57
1.85 1.57

(Changed to a 450watt power supply, samething, swap back to my old 145watt one)

So now Im stucked with 1.75v @ 1.71v. But the TBRED seems to be running 100% stable in windows. However, in windows xp, it shows as a Duron with 256kb cache???? If you trying to make the Athlon XP run in your KT7 motherboard, try to unlock is multiplier. Now I'm running at 101x20 (in bios i set it to 12.5x).... I dont know how the KT7 set their multiplier, try to google it like Abit KT7 Athlon XP something like that...

I have an Abit KT7 board that used to have a Duron 800 in it. I just replaced the Duron with an Athlon XP 1800+ (Palomino). Its supposed to run at 133x11.5=1533MHZ. I have mine set at 100x11.5 and it's been running great for almost 2 weeks. No problems at all. The only problem I had when I first put it in was the multiplier was set below the 11.5 due to the Duron being in before and the system wouldn't post every time. I then put it back to the actual multiplier it's supposed to run at since I think it's a locked chip and it runs great. I'm running at the default core voltage of 1.75...thinking about droppiing to 1.65 to see if it will run a a little cooler. Currently running idle at about 42C and at load about 50C. Not too bad...but I think being underclocked it should run stably on a lower core voltage setting.
