anyone run 4.0 , 24/7 on water? seems the magic number is 3.7 to 3.8ghz

3.5Ghz

Heheh, I just got my 720BE and I've done minor tweaks, but already I've hit 3.5Ghz where I was REALLY struggling to get 3.25Ghz out of my 8750BE.

I love this thing ^_^

Welcome to the 3.5Ghz club. ;-)

Put my name down...I have a PII 945/ASUS M3A79-T Deluxe coming soon, ascstingers rig.

What kind of 3d 06 scores you getting from that little speed bump?

Not a clue. I don't run benchmarks, I only run stability tests heh.

 

[PP Mguire]

My 720 is sitting at 3.6 stable.

 

[ShadowFold]

I might get a 710 and let it sit at 3ghz. I don't really need anything more for gaming.

 

[Flyordie]

I may end up selling my X4 920... but idk if anyone would be interested in it since its not a BE.
Expected price tag for the CPU alone- $155. W/ HSF-$165 (mainly due to shipping cost increase. ;-( )
Pointers and Facts on the 920 I have-
Batch- 0849
Voltage- Never has seen over 1.45V
OC- Has only seen 4Ghz once.
Although the X4 940 BE got a small price cut... $200 shipped now.

I have not yet decided if I want to sell it though... It OCs good, but the bus on this board is complete crap imho so haven't been able to push it to its max.

 

[ShadowFold]

If I get the money I think I'm getting next week I might grab that 920!

You would be buying a "Professionally Conditioned"* Phenom II then.
Everyone should condition their CPUs before they get them... enabled my X2 3800+ to attain 2.8Ghz with only 1.35V (1.322V after droop).
To condition my PII I dropped voltage to 1.25V and cranked the core speed to 3.0Ghz and left it burn in for 24 hrs.
Netted me an extra I assume 130-150Mhz since it does 3.4-3.5Ghz on 1.35V.

*Only works on 100% unused processor cores

 

[ShadowFold]

I don't get it lol

 

[Super XP]

Yes, I heard of this B4. Never had a chance to try it out because most CPU's are already used in terms of testing before they are shipped off.

I've noticed anything after 3.70 GHz requires a lot of vCore.

 

[Flyordie]

Shadow, doing that enables the silicon to settle in at a reduced voltage, meaning it will begin to love that low voltage and get used to it. We then rip the bottle away and give it hell.

so your "burning in" the chip. I have done that before. did that with every CPU i have had in the last 2 years. But i did it alittle different. I would leave it at stock speed lowest stable voltage, stress for 24hrs up the speed stress 8hrs up speed little more stress again for 8hr. I would keep doing that till it became unstable then lower it to fastest stable speed on that voltage stress for about a week (using F@H mostly sometimes orthos) then try that speed it became unstable at before again...
results.... It worked about 75% of the time.
exp 1.8ghz@1v stable 1.9ghz@1v unstable before "burn-in " about a week later 1.9ghz@1v

then after thats done clock the hell out of it...
exp. 1.8ghz @1v to 3.1ghz@1.4v

 

[Fitseries3]

sorry if i come off a bit harsh here but...


4.2ghz max? seriously?

someone loan me their chip and board. i'll get 5ghz up on the board for us here at TPU.

i'll also post some 3dm vantage scores up so ppl stop doggin the PII.

not trying to start a flamewar here. im no fanboy of any camp

cdawall got higher then 4.2ghz he got like 4.7+ghz (i think)

EDIT: it was over 4.8ghz

The problem is most of us using our P2s are on air. Id get alot higher if i wasnt on air.

 

[exodusprime1337]

i wish i could get higher... tbh i moved to water and at 1.5 i get about 30c idle and 45 load with prime going torture test... but i can't seem to post and bench at anything higher... like 3.8 is the max.. i've even tried running it here on a day where it snowed and was like -4c out and opened all the windows put fans in them to push cold air in and chill the shit... still no luck.. i moved to water on the hopes i could hit 3.9-4.0Ghz and still couldn't do it.... maybe i'm doing something wrong.. idk..

on another note what is the max voltage and temp i can safely hit while under water?

I doubt it, us on water haven't really been able to get past 3.9 with. (With a few exceptions *cough*cdawall)

I've been wondering the same thing, I haven't been able to hold stability long enough to get a screen off at anything over 3.8ghz, I'd pump more volts through my system, but I don't know the max the 45nm chips can take... I know my old 9550 took 1.7v pretty well.

 

[PP Mguire]

cdawall also goes for insane volts which i would do if i had water as well or DICE.

 

[Fitseries3]

wow....

just lend me your setup... someone.

i can paypal you some money for insurance lol.

Not even water or DICE can help in volts all the time. He's risking blowing his CPU every time he does it.... but I guess that crazy volts thing is his territory.
Realistically CPUs are like a fuse that can crunch numbers, hand a 2A fuse 5A and it dies, give a 1.35v cpu 1.8v and the same thing can happen.

my CPU ran on 1.45V and ive known Athlons even the latest to love higher volts.

That's true that some CPUs love higher volts, but any circuit can only handle a certain amount of wattage, amperage, and voltage.
If you've ever seen the episode of Mythbusters where they do the Christmas lights setting a tree on fire it has a good example. It's the part where Adam is using a 10gauge extension cord higher than it's rated capacity and the cord gets really f'ing hot and melts.
