will turning off hyperthreading allow a more stable overclock?

[AnUnQuietMind]

im currently running a 3770k at 4.5ghz with 1.24voltage my cpu and gpu are both watercooled. would disabling hyper threading allow me to get a stable yet higher overclock? and if so what the max voltage i should get near without long term dmg to my cpu considering it is well cooled.

Perhaps

 

but whats the point? It would just be an 100$ more expensive i5. Under most circumstances 1.3v, under water and good temps I would be comfortable with no more than 1.4v

Aren't i7's higher binned?

ive gotten it to 4.6 stable but only after moving the voltage to 1.35 and was wary of getting too close to the dreaded "1.4v" zone

[Rasmuff]

I dont think it really affects much doing that. Thats actually kinda a little high for 4.6Ghz but i guess its just the difference in chips because i got 4.5Ghz with 1.22V mainly cause i didnt feel like pushing it and shortening the life of my Cpu  but for most applications 4.5Ghz works perfectly fine. So you could back down a bit on the clock and lower the Voltage.

 

Edit: It also depends on what kind of Cpu Cooler you using, cause the better it is the less high voltage is scary.

you can look up my build but im cooling the 3770k and a radeon 7950 with a 240mm rad and a 200mm rad at 4.5ghz the cpu dosnt get above 48c and the gpu under full load OC to 1175mhz hovers just below 50c

no disabling c states and power saving features does. increasing your voltage does as well, because you are under water 1.35vish will be fine for a good few years, at 1.4v its going to last 1-2years and anything above that is benching only.

What were you thinking of having as your clock for the CPU?

[AnUnQuietMind]

was hoping for 4.8ghz stable the chipset is being run on a asus sabertooth z77

Even if people claim they are, there's always no evidence to backup.. It's not something you just can make a fact of unless Intel claims it which they didnt yet.

@Op it just depends on your CPU every chip is different but most likely it won't; maybe you need some less mV's on the core but nothing will be drastically different. Hyperthreading adds probs like 1-3° so it's not going to make a difference on your temps really.

Can someone tell me why over 1.4v is bad for Intel CPUs? My AMD CPU isn't that far away from 1.4v on stock..

turning of HT should help, because like someone said i7's are binned higher. Thus are usually better chips than i7's, but not always. For instance, I have a 2600k and a 2500k, both are running @ stock on hyper 212 coolers. my 2600 folds on 7 cores 24/7 @ about 45c. my 2500k sits at idle (but at full Ghz idle) at 36c.... and folds up in the mid 60's. Sure, maybe I have a decent 2600 and a bad 2500. But still, a HT off i7 should go higher than a i5. 

 

All that considered, unless you are going for bragging rights, I would leave HT on and sacrifice the few hz

[AnUnQuietMind]

amd is differnt just cause you can crazy overclock them the performance you see from it isnt as high as slight overclock on intel (i own both brands btw) but 1.4v usualy gets close to when you start heating the backside of the chip and destroying your motherboards pcb ive seen browned motherboard backing from too high of voltage.

How do you mean c states will help him get a higher clock?

1.45V is the electromigration zone for sandy bridge. With ivy bridges its just impossible to sit at that vcore without delidding the chip.

its not bad on intel cpu's its bad on sandy, ivy, and haswell cpu's but it depends on your cooling. on a sandy 1.5v is ok underwater but this would probably kill most haswells as they are designed to run at a lower voltage.

Aren't i7's higher binned?

they aren't binned as such they're cores are just taken from the centre of the silicon discs so they are generally better, but it also depends on the batch.

could be the case, the 4670k does overclock better than the 4770k
