alright, since this is most likely the best place to ask:

i have a Athlon 64 3800+ toledo with an e6 stepping, and what i need to know is how far i can drop the core voltage with this particular processor. Right now im at 1.250 at stock clock and prime95 hasnt even coughed at me, but im still not sure how much further i can drop it without compromising the stability. Anyone care to give me an idea of when i should stop dropping the core voltage?

the reason i want to do this is to drop the amount of waste heat this processor is dumping into the air in my room, and by itself at full load its dumping more heat than my sig rig in its entirety, which means my room gets hot, and everything in my room, me included, begins to roast in the 85+F temps

Who's down?
I am.....

Good to hear the buzz about a competition. Clubs like this one should do this on occasion since it only helps to improve things for all members in the long run.

I can't say I'd do so well in 3D benchies since my cards are old now and trying to save a few $$ to get a new one or two but it should be fun anyway.
Let's do this.

We need to start on deciding what benchies we 'd be running. Nuclearus MC is a decent one since it's multi-threaded and WPrime is another. Of course Super PI is one we'd probrably do too.

I'd also suggest a separate thread just for this, like I was running over at EOCF at one time.
http://forums.extremeoverclocking.co...d.php?t=293244

And pray Drewmeister doesn't show up or it's over.

Speaking of this club/thread, might have been mentioned earlier but noted it's had over 1,000,000 views now. Probrably one of if not the biggest count of views in this entire forum.

I don't know what you had in mind joe so I figured I'd throw out some idea's just in case your not entirely sure on the details of the event to take place.

How about some kind of max or high speed capability contest, followed by max stable speeds verified by a duration of timed benchmarks, followed by some kind of gaming in a series of eliminations like in a pool tournament leading up to the podium of 1st through 3rd place and then have some kind of way to calculate a Grand Event winner by means of averageing each events scrore to give a more over all picture of each persons participation and put forth efforts in this event.

For example:

Lets say one person gets the highest overclock possible on on a CPU and is given so many points for 1st place. Now lets just say 10 points for first place in each event but only if there are only 10 participants. Now if there was 15 participants than each event would award 15 points for first place and so on. I think you can see where I'm going with this.

Basically if there were 5 events then we could add the sum of every point per the 5 events to tally up each participants points count then divide it by 5 for an over all average points summary for each participant.

If there is a game involved then it should be one that is free or can be downloaded fairly easy and with enough time for each participant to practice and hone in their individual skills and tacticks while keeping in mind that there is a specific set of rules that could lead to any of the following, DQ, DNF or DNQ etc etc.

So now with all that in mind say Biff enteres in all 5 events

Events:

1 CPU Highest clock
2 Ram Highest clock
3 Max Ram Bandwidth
4 highest stable system overclock backed by a battery of stability tests and benchmarks
5 Gaming of some sort

Now after all 5 events Biff scores the following in each event

1: 6 points
2: 9 points
3: 2 Points
4: 15 Points
5: 7 points

We would add the sum of his points to give us his total points count of 39 points then we'd divide his total points count by the number of events he scored to give us his total average participation point count of 7.8 points. So in this example he would be some where in the range of 7th to 8th place depeding on how others finish and in the event of of a tie we could hold some kind of tie breaker where each of the persons in the tie would have to either blog or explain in great detail how they felt about all the events and who they think should win the tie and why.

I like fairness in contests but sadly there is not always fairness in contests. This makes me think that we could apoing one or several Referies like PIO &/or others who are either retired or nestalgic 939er's that would have a neutral standing on who wins and would be able to initiate DQ's if any participants actions permit those decisions with out prejudice or favoritism and have the ability to submit evidence for needed officialling upon requests.

IDK what you had in mind joe but if ony one of my idea's sounds good then I'm glad I could help.

Cheers with Rootbeers,

N2Gaming

Cyrious just push the voltage as low as you can while maintaining stabilty. I don't think you can hurt any thing by doing so and if I'm wrong about that then some one else please chime in.

Cyrious, unfortunately there's really no "standard" answer to your question. Each chip is different in terms of its reactions to changes in core voltage.

I think pioneerisloud has got some good experience as far as dropping his VCore on his chip. I seem to recall him posting that he's gone as low as 1.2V or something like that. I'd ask him for more specifics.

Kryton: Oh wow! I didn't realize we've been that popular!

N2G: Dunno yet what format our next contest will have, but I have to say I REALLY like the multi-format context you've laid out. What do the rest of you think?

(I'll check back later. My beloved 49ers may finally be about to break their duck and get their first win!)

^ I think its cool, but it will be super time consuming. Ya'll should wait until I get into college before doing a time consuming contest .

I also like N2's ideas.
Let Pio along with another judge (Or few of them) do their thing as refs.

nategr8ns, it's not as time consuming as you'd think.

well, after about 6 hours of nonstop prime95 and dropping the voltage incrementally during that run, i am down to 1.1V which is as low as i can get it through software, as my board cant do it through bios (crappy HP board with a slightly less crappy gateway bios). Clock speed is still at stock, and load temps went from 50-52C to a much cooler 38C. Guess i have a decent chip that can run at the minimum VID at the max multiplier. If i had a better board, i would overclock it.

hopefully, it shouldnt crap out on me, and in the meantime i must get my seedbox configured and ready to rock.

My Opteron was able to stabilize at 1.0v (the lowest I could go). I was stable there up to 2.4GHz. 2.7GHz took 1.12v. 2.8GHz took 1.20v. And 3.0GHz took 1.36v.

It's all up to how lucky your chip is with voltage. Turn your voltage down, and stress it is all I can tell you.

There's no shame in that . If I still had my Opty rig, it would be running 2.7GHz with 1.12v for HTPC use. I miss that rig.
