What hacking RC5 do and what is RC5?

 

[Duckers]

you mean cracking RC5

 

[GC23]

sorry , i mean cracking

 

[GC23]

I guees you need a nice powerful computer to do that huh??? I dont think that my k62 450 will do the trick

 

[GC23]

FIXED......

I guees you need a nice powerful computer to do that huh??? I dont think that my k62 450 WONT do the trick

 

[Prodigy^]

nah anyone can kick in, it just uses the part of your CPU power that's not being currently used....

 

[ltk007]

You don't need a powerful computer. Anything is worth contributing. You can have it run on more than one computer to boost your stats. You can put it on a friend's or something. If you're not using RC5 you're wasting you processing power. I have a PII 266 cracking and it does ok. K6IIs are pretty good, I think they are better than celerons.

 

[Budman]

It's just a program that will make you cpu run as hot as it can & there's no hope in hell that you will win $1000 prize .

Sounds pretty useless doesnt it?

That's because it is.

Holy-post-a-roma, Batman....


"...I dont think that my k62 450 WONT do the trick

So you think that your k6s 350 will do the trick, right? =)

 

[Soccerman]

yeah no hope in hell anyone will win this prize.. well.. anyone except RUSS! he's got a hope in hell.

I'm running it on a K6-2 400@420. Don't care how slow I am, I just enjoy helping the team!

 

[Budman]

Agreed Soccerman,Only Russ can win this thing.

If you cant stand the heat budman, STFU

Rc5 is a team effort to promote AnandTech and give back some of what the site gives us, I have read a few threads where you are whining about heat, I have been running Rc5 for more than a year 24 hours a day 7 days a week on a c366@566 at 2.3 volts and heat is not a problem for me. If you dont want to run Rc5, or cant run it because of inferior equipment or inadequate cooling thats your problem, if it is not obvious to you then think about it for a minute, Rc5 is running on hundreds of thousands of computers worldwide, if your system cant cut it thats too bad, but why do you feel the need to try and discourage others who are interested in Rc5 and Team AnandTech? do you perhaps have loyalties elsewhere?

 

[Budman]

Slacker why dont you STFU

I am running a Asus K7v 800mhz Athlon Artic circle with Acer pc100 ram , in a Aopen Hx08 Case with Aopen Tnt2 card,Wd Hd,Pioneer DVD10x ,Aopen 6x4x24cdrw,sony floppy,intel 10/100 NIC. does this sound like crap to you ?

no it's not,Why dont you do all of us a favor & go preach your BS somewhere else.

I am just warning people that RC5 does make you cpu hotter that normal.

if you dont like it then you can kiss my a$$

 

[Jator]

Guys,

I've been following some of the posts involving Budman. THough I disagree with his tactics, I do agree with him that RC5 does contribute to more heat. A lot. Probably not. A little. Definetly. But you know what, most of us are OCers, and we want to get our money's worth, and what better way to test a oc processor.

As for the debate BudMan wishes to participate in, he's entitled to his opinion and I welcome it. But also realize you are in the minority here and not everyone here is as patient as I am.

So let him have his say, and we will address it in kind. Let's try and keep things civil, and if he keeps it up well drag him into a game of UT and kick his virtual buTT!!!

 

[Budman]

paulson,

what kinda cooling do you need on that 1ghz Athlon to keep it cool & run RC5 ??

 

[Budman]

Finally some sense here.

I did not use any bad words until slacker told me to STFU.

I am only voicing my opinion on the subject & that's ALL.

No need to get personal here.

 

[DanC]

Everything could be solved by changing your dnetc.ini file to read
"russ@compucheap.com"

Budman, how much hotter does RC5 make your system run?

I have a couple of dual-processor systems, and they run RC5 24/7, even while gaming, with no ill effects. They'll run RC5 at speeds that they won't run Unreal Tournament at, so I don't think RC5 is really as hard on CPUs as you might imagine. Sure, it uses 100% of the CPU cycles, but that doesn't mean that it is using all the CPU's transistors. Someone correct me if I'm wrong, but doesn't RC5 fit into the L1 cache of a typical P6-type CPU? Hmmm...! Anyway, I really am not worried about it shortening the life of my equipment.

As for why to bother with the RC5-64 Challenge, I see your point but I can't stop, I'm enjoying being on this Team! Don't take life too seriously there, friend, we could be doing worse things...

 

[Budman]

Ok to answer your question mechbgon, while gaming rc5 will reduce it's consummation an will not take any cpu cycles needed by your game, hence you will not see any difference while gaming.

But why your system is not busy it will halt CPU cycles & thus keep cooler.

But if you are running RC5 that is talking all the spare CPU cycles away from sleeping, then your CPU will keep hot.

But if you do not run RC5 then the CPU will use this time to shut itself off & thus it will get colder.


Then you can see why I don?t run RC5. But this is MY choice but you are free to choose otherwise

<< Ok to answer your question mechbgon, while gaming rc5 will reduce it's consummation an will not take any cpu cycles needed by your game, hence you will not see any difference while gaming. >>

That's kinda the point...



<< But why your system is not busy it will halt CPU cycles &amp; thus keep cooler. >>

Only if you are running an OS that uses the hlt command. Or, if you are specifically running something like RAIN, CPUidle, or the other handful of progs that do it. Win NT does it. I believe Linux does it as well (not certain on that one).



<< But if you are running RC5 that is talking all the spare CPU cycles away from sleeping, then your CPU will keep hot. >>

Again, only if you are using the hlt command, because while rc5 (and other programs) will make it run hotter because they are actually USING the cpu, the other parts ARE NOT turned off unless you have a program to make them do so.



<< But if you do not run RC5 then the CPU will use this time to shut itself off &amp; thus it will get colder. >>

I think that's the 3rd time you've said that, just in a different way




<< Then you can see why I don?t run RC5. But this is MY choice but you are free to choose otherwise >>

I completely agree. I run it, because i like to. There are times when its a good idea not to. Its everyone's preference to do as they choose.

 

[mechBgon]

No problem with that, Budman... but do you have any hard numbers? I'm going to fire up Motherboard Monitor and then let my system idle, and then start up RC5 and see how much it heats it up. This will be interesting... don't know why I never tried this before. I'll post my results in a few...

 

[Budman]

I agree 100% with you BurntKooshie.



<< . Its everyone's preference to do as they choose >>



I am just telling people what RC5 will do, But the are the only ones who can decide.

 

[BurntKooshie]

You make it sound as if its an evil...YES, in comparison to a system using the hlt command, it WILL run hotter. YES, you save power by not doing so. What I don't understand, is why you seem to so vehemenently disagree with using it (though you and I agree that its up to the individual ). I quote:

<< It's just a program that will make you cpu run as hot as it can &amp; there's no hope in hell that you will win $1000 prize .

Sounds pretty useless doesnt it?

That's because it is. >>

That's about like saying &quot;AMD is stupid because the Athlon uses more power than intels cpu's&quot; or &quot;AMD RULEZ!&quot; You can say that it makes a CPU run hotter than it otherwise would if they were using WIN NT, or some other OS that does the hlt instruction, or a cooler program. But its not useless. Distributed.net runs other programs as well. Know about OGR? Its an effort to find optimal golimn (spelling?) rulers...soemthing i don't direclty know about, but people have told me that they are very important in telescopes....tell me THAT'S not useful...tell me that proving/disproving how strong an encryption scheme isn't in some way useful...tell me that finding the optimal storage medium for radioactive waste isn't useful...in some cases, its best to let a CPU run as cool as possible using as little power as possible....but that's not always the case.

Hmmkay, here is my test system's spec:

Abit BP6 with dual Celeron 400@552MHz at 2.20V
TNT2
Voodoo2
Network card
the usual drives
80mm case fan in front
80mm case fan in rear
80mm fan in power supply
120mm Panaflo blowhole fan on side aiming half into cards, half into CPU area
Alpha 6035 heatsinks with YS Tech 60mm fans, set to pull away from sinks

I booted up and let the system equalize for a minute, then ran Motherboard monitor and had it average 40 samples, one every 5 seconds. Then I stopped MBM, started the Dnet client, let it equalize for a minute, and started MBM and had it average the next 40 samples. Results:

Full idle in Win2kPro:
CPU1 94.41F
CPU2 95.31F
Motherboard sensor 98.60F

Dnet client running:
CPU1 94.91F
CPU2 95.72F
Motherboard sensor 99.28F

Increase in temperature due to Dnet client:
CPU1 +0.50F
CPU2 +0.41F
Motherboard sensor +0.68

On the Abit BP6, the temperature sensor for the CPUs is in contact with the underside of the CPU, which is not quite as good as direct core readings, but still a pretty good relative indicator. Based on these readings, I would have to conclude that there is not a meaningful temperature increase when running the Distributed.net RC5 client on my system.
