Intel cpus at UVOC, post & share your result here !

[bing]

@treatmentx

Thanks for the update ! Really appreciate your patience through that boring moment on stability test !

I'd say wow on the UVOC, that is really low voltage you got there !

Now one important note that I need to clarify, that "Best OC" is the best OC you can hit while staying on that low voltage like that 1.0750 VCore, so its not the usual OVOC !

Anyway, still waiting for that final result too and the table at 1st post is now updated with your "PRELIMINARY" result as well !

Regarding the temperature, honestly I would'nt worry too much, remember, its UVOC so the CPU temp will run as lowest as you can get, not like the usual OVOC.

Just take your time, and I'm agree that it can be really boring especially for OC-er which "naturally" want the best OVOC from their rig.

Tips, just leave it on stability test when you're going to sleep ! he..he..

No worry, I'm patience & cool waiting for a really good & consistent final result !

Now, to others, again, mind post your UVOC please ?​

Unfortunately I'm seeing some 350FSB wall on my P5N32-E SLI board, I'm still working on it though, we'll see what happens.

..<sigh> ...looks like not many interested in under voltage OC anymore, another bump !


C'mon folks, please ?

I think most around here just haven't gotten their G0 yet. Mine should arrive on Friday and I will post results soon after

SH0DAN, thanks ! Nice wall paper you got there, for sure it will heat up that monitor for few degrees !

The table at the 1st post is updated, check your name there and "your other missing fields" !

Can't wait till your UVOC result !


To others :

Please, if you got spare time after you're happy with your OVOC, mind try & share you OVOC result here ?

Watch for 1st post of this thread, updated with OcF's style tables !

Hope it will attract more participants ! ... <sigh>

And... please .... submit the result with the info as requested in the 1st post !

 

[jason4207]

Nice table! I had already planned on contributing, but I think it will definitely help attract more participants. My e6750 will be here Tue or Wed...I hope. It may take me a day or so to get up and running b/c I want my case to be perfect before I start anything. No components on a table for me...the wife won't have it.

I'm trying to get a hold of a G0 x3210, and will contribute those results as well if I can ever find one of those elusive devils!

 

[bing]

Jason ! Many thanks for the encouragement !
Cause I begin to wonder if this thread will slowly sink down under untill its forgotten !

I understand most people will or definately aim for max OVOC, hey, this is OC forum here !
And also UVOC on stability test sometimes can be boring, I concur !

But once we have enough samples, I have a "feeling" that the consolidated table will generates something interesting.

Expecting your results soon here, again thanks !



For those who had viewed this thread before, I repeat, a new updated table at the 1st post ! Hope you like it !


For other upcoming participants,

Please read the 1st post thoroughly especially on the format requirement, cause it will be meaningless if it's not complete.

Check the table your self to see "what if" your data is not complete.
Again, for stability test, I know it is boring, please ... not in minutes, please do it at least for few hours or when you're going to sleep.

Q6600 G0 just arrived today!
VID: 1.2875
Lowest VCore: 1.0875
Load/Idle: 47/29

Set VCore at 1.0875 in the bios, real VCore on load was about 1.024. I couldn't get much higher clocks though, topped out at around 270 with the same voltage

I think I need to reseat as Core 0 and 3 are much hotter than 1 and 2, or is this normal? Ambient is about 29C
Ultra-120 Extreme

I've got that exact same processor, right down to the pack date and the 760 in the batch number. For me cores 0 and 1 are always identical to each other, and cores 2 and 3 are always identical to each other. But cores 2 and 3 are always 4°-5° lower than cores 0 and 1. Specs are as in sig, box #1.

@ishould,

Thanks ! You're the 1st to post the quad UVOC result !
It looks like your Orthos was having trouble, try this Prime95 v25.3, its much better and no hassle assigning CPU affinitiy.

The table is updated with your result, please check it again, are you sure your Ultra is seated well ?

"Ignore" the absolute temp since they're not accurate, see the table for comparison ? Also your idle temp is same as your ambient which is theoritically impossible, but because of inaccuracy at absolute reading, this can happened and normal.

Just focus at the Delta temperature between load and idle, usually it is very accurate compared to the absolute readings.

Oh yeah, mind test that UVOC at FSB 270 a little more please ? Maybe hours ?

If there is some changes/updates in your data, please repost, I will update the table to reflect it.


@Sorin

What are you doing here ? ... j/k
Go test out your CPU at UVOC and report back here ....... please ?

 

[treatmentx]

oops sorry, been busy bitching people out because of P5N32-E FSB wall for quads... actually only bitching at ASUS, hopefully people would notice so would think twice about their service... just a note, EVGA has replaced people who have the 680i wall (specifically the GTL Ref voltage being inadequate for Quads)... asus just ignores our pleads...

anyway

best overclock at that lowest voltage was 267.25 x 9 multi, 2.405ghz

Table update done, thanks treatmentx !

Thanks SaCkS !

The VID you supplied, I believe its typo isn't it ? Coretemp SS is showing 1.2750 V instead of 1.1275 V ! Table at 1st post is updated with 1.2750 V.

From the table, it looks like your temp delta is similiar with others except for "ishould".
Sounds like your HSF mounts is OK !

Though not crucial, what ambient temp ?

Can't wait for your best uvoc result on that lowest vcore !


To ishould !

If you're reading this post, maybe you should take a look at the table.

I think you need to do something about the cooling there, dunno ? Maybe reseat ? reapply TIM ? or lapping ?

yep typo on vid, I keep ambient right around 65 to 70F so 18 to 22C.

Don't know on the overclock, right now I'm 15 minutes into 2430, 2440 lasted about 45 minutes.

 

[bing]

GTengineer, thank you ! Another complete data set !

Looks like your temp is on par with others, check the table.

Also thanks for the max ovoc result, although I will not put into the table "yet" , it will serve as a good reference for others that might interest on your max ovoc.

Well, since the table is growing now, although still small samples, it looks like it is starting to show some "pattern" ! ;D

What pattern ? No, I can't tell it yet since its too early, make one your own !

Beauty is in the eyes of beholder !

Well, I suggest just stick to 2430 to see how long can it goes ! Any chance you try lower multi but higher FSB ?

Thanks for the patience ! Drink on me !

Not right now, this bios has the multi locked, my other option is to update to a beta bios, which I will do once my Bios Saviour arrives.
