4790k Max Safe voltage?

[abbasmo2]

The title says it all

 

I want to overclock it as much as i can but be able to use it for along time, maybe 5 years? LOL

 

I know the 4770k should be 1.3v or under as a safe overclock, so what about the 4790K? it has a boost clock of 4.4 anyways so i was thinking of 4.6ghz atleasT and would like to go higher, so once again

 

whats the highest safe voltage i can get at?

 

thanks for any replies

Pretty much the same as a 4770k.

Just don't go above 1.3v for 24/7 use.

It's the current that's the problem...and the discharge.

i will be running  a cooler master neptoon 280L so keep it cool as possible, so regardless of heat, going above 1.3v will still damage the cpu in the long run? its what i understand from you comment

If you have the means to keep the temperatures reasonable, 1.4v should be fine for 24/7 use on watercooling, ~1.35v on high end air should be fine.

 

I believe @ProKoN has had his 4770k at 1.45v for a year now with no noticeable issues.

so i guess if i go around 1.325vs for example at 4.8ghz with my closed loop cooler (CM neptop 280L) and have reasonable temps i am good?

should be...your warranty is void now and voltage does reduce the lifespan of your CPU, what are you using this chip for? why do you need such an high overclock? i would consider 1.3v a safe and reasonable voltage under water cooling for long time use...

I'm a chicken my 4770K does 4.3ghz at 1.19v and i'm happy with that my GPU is the bottleneck anyway in every games that i play...i'm also planning on using this cpu for 3 or 4 years at least so i dont want to reduce its lifespan.

There's a limit to the amount of heat you can dissipate from a processor, and after a certain point there's heat that can't be dissipated from the IHS. I'd say stay around 1.35v and you'll be fine.

LOL i am also the same way, i will most likely not go over 1.3 just inquiring about the possibilities if i could. and LOL at the gpu bottle neck, which gpu is it if i may ask?

Also i will be doing alot of video editing so the speeds would help and also the occasional fps boost in games, even if its like 1 fps.  B)

4.3ghz at 1.19volts for the 4770k is nice thats a 800hz OC!

ok thx alot!

the GPU i'm using is an overclocked GTX 780... 95%+ of the games out there are GPU bound on my machine so theres no need for such a strong processor but hey 1.19v is almost the stock value so why not...but i would not push 1.3v through it just for the kick...rendering video faster is worth an overclock though i agree on that.

Maybe you should set yourself with 2 different OC profile in your bios that way when you do normal daily stuff and gaming you do it at 1.2v and when you render or encode videos and stuff like that you push it at 1.3v? just a thought.

I was thinking the same thing, the asus z97 mobos have the utility so you can set profiles for certain programs and have the cpu run at certain voltages. Also if i wasnt gona video edit i would still go with the i7 because after all, it is an i7....

Hello there, I got my 4790k recently,
 
I'm on air, using noctua NH-14US only one Fan and here's what I got here using 1.27V  at 48 Multiplier. Note that this setup pass intel burn test as shown in image but it can't do prime95 well it makes a BSOD with the blend test(not the small fft)

 

I was able to get 47X 101 for 4.749 stable with prime 95 no BSOD with about the same voltage.

 

My temps show I should go higher with my multiplier but hell I'm going to test it right now!

 

see you soon if my CPU lives throught it.

[hitako]

Well here is what I've got, 4.9 multiplier with a voltage of 1.325 wich is about 10% more than what I would be confortable to use, my temps gots really high, I was able to complete the intel burn test at 1.3 too but it wasn't really that stable, it sometimes BSOD.

I had some results in some test going over 132 G flops but I suspect with those temps I must throttle so I am averaging about 131 G flops.

 

So, I think that it is possible to go to 5 with aircooler, probly with cryorig r1 ultimate or noctua NH-D15, but my cooler is already compromising  my motherboard well enaugh and I'm comfortable at 4.7Ghz with it as an ok OC at 1.235V with temps around 65 C to 70 C with intelburn test.

 

My motherboard is an asus Z97-A motherboard and my power supply is a really good EVGA 850W supernova gold certified.

My casing is a NZXT phantom410, I like it's airflow and design. Graphic card, gigabite gtx970 g1 and my memory 4x 8 GB ballistix tactical low profile  at 2133 - 10-9-10-1t

 

5GHZ air is possible, intel was right, but, I guess only 5% of the chip can, it is luck of the draw.

@hitako

 

seems like you have been doing a bit of overclocking.

 

post your cinebench scores here.

Not to bring up an old thread or anything but is this still right I can go to 1.4 with my h110 cooler ?

I wouldn't without a delid.

Is it worth deliding? Can I do it my self ?

Delidding and CLU is a huuuuuuge temp drop.  Usually 15-25c drops at higher voltages.

How do I do this or where can I get it done dude ? 

[Mick Naughty]

My 4790k is on a 4.7 oc. Think it's one of the presets when I bouht the board. Think it runs at 1.38v. Haven't messed with it at all as I hate CPU oc'ing. Sits at 40c. 6 hour game sessions on bf1 90-95% usage it gets up to 45c some maps.

Linus did a video on this a while ago. Do carefully consider what is said in the thumbnail though.

If you don't want to do it yourself, you can send it off to Silicon Lottery and they can do it for you.  If you don't know what you're doing, that's probably the best bet.  Either way you're going to have to spend some money so you might as well pay them to do it.  If they screw it up, they replace it.
