5.1GHz 980-X On...... Water! *Validated*

[Mutant_Tractor]

Great run dude!
I got 5.2GHz last night on my water, my EK full cover block arrived today so ill hopefully hit 5.3GHz today,
Also got 3.16s WPrime32M last night
Ill post up the proof soon

[Mutant_Tractor]

Thought id update here rather than a new thread

5.2263GHz on water:

Is that a safe voltage?

And while im at it, i got a new full cover block from EK and dropped NB and VREG temps by 20*C!

Last night I also did a WPrime run @ 5.1GHz (3.14s Trying to beat a guy on DICE with 3.110s):

1.729V... is that an okay voltage?
I mean my max temp was ~ 50*C, but you guys keep telling me 1.5V + = dead chip? WTH?

I really think i can so 3.1s> on water but im afraid im using too much voltage or using it in the wrong places, if you guys want i can post up my BIOS template?

Cheers guys

1.55V vCore was the max safe voltage for 45nm i7 according to Intel, and it should be even lower for 32nm CPUs. You do the math...

[Mutant_Tractor]

Hahaha, is that running on their stock cooler? :P

[zalbard]

Regardless of cooling. 45nm i7s are much hotter, though.

[Mutant_Tractor]

5.3GHz

Ahhh, so its the cooling that determins "safe" voltage?

[zalbard]

No. Well, to make it more simple... The first thing to care about is the temperature. Even if you're only using 1.1V, if the chip is running at 95C you're slowly killing it. But once your temperatures are fine, let's say under 70C (for instance), then this "max safe voltage" comes into play. And no matter how good your cooling is, once you're past that your chip is slowly degrading.
Intel says that max safe vCore for 45nm i7 is 1.55V.

[Mutant_Tractor]

Ahh okay,
Im sitting @ 36*C Idle and the NB + VREG are at 32*C + 35*C @ 4.6GHz + 1.55VCore

I guess ill lower my voltage then :P

So confused how this thread has 82 responses and ~3k view and there is nothing regarding Xtreme Overclocking going on here.

[Mutant_Tractor]

Can someone move it

[Mutant_Tractor]

Just an update to do with the thread:

From the section rules:

The Xtreme Overclocking section is for top-end EXTREME overclocks and large achievements. Generally if you aren't at least on dry ice, this is the wrong section. If you have an absolutely EXCEPTIONAL air, water or single stage overclock, then it's acceptable.

[Badfastbusa]

It looks like some pretty exceptional overclocking to me.

[scook9]

It is crazy what these chips can do....can't wait till the poor college students can afford them haha

[Mutant_Tractor]

Poor college student right here

[Mutant_Tractor]

@Mods - Can i have a thread name change from 5.1GHz to 5.3GHz as per the result above
Cheers guys!
Myles

LN2 results coming soon

O really CPU-Z screenies don't mean that much to me... wished these all did +/-6ghz like the early ES batches, apparently they do not...

hi guys, got an Q3FE here, running this CPU on 4,4 Ghz i need 1,4V to get it primestable... Will this CPU die with 1,376 Vcore and 1,29 VTT quickly? On 25°C water so far.

Those voltages so far have seemed safe for everyone.

[Krautmaster]

thanks Mr. Tool - i like Tool btw xD

Problem that i have with the A0 is that DFI does not support uncore = 1,5x Mem clock - so i can't reach my prefered 2 ghz mem clock. With retail CPU, you can go on 1,5x but i think DFi will not fix this problem for A0 any more...

Intel specs say 1,375 V max für 980 - so i think i'm on save voltages so far. 4,4 Ghz 24/7 will be fine. C1E works fine so the cpu will only see 1,4V while i'm encoding bluerays.
