My 4760K overclocking

[KermitFTW]

Hello LTT people!

It's me again

 

Ok, so I'm trying to OC my Haswell i5 4760K (again, after a few years of running stock after some failed attempts), and seems that either my CPU is trash, or that I have no idea what I'm doing...

This time around I'm trying to follow the instructions that were given on ProKon's thread:

 

So I'm using XTU to stress test my CPU, and right now I can't even do the 5 min stress test without crashing on anything below 1.29V on the core voltage at 4.4GHz (temps are peaking at 75C).

So I wanna make sure that I'm doing everything right before going on with the 8 hour stress test, Right now I have the core voltage at 1.29V and core multiplier at 44, my VRIN at 1.9V (whice is the VCCIN, right..?), I've set the memory to 133 at 1.5V as the guide says.

Those are the all the settings that I've changed, is there anything else I'm missing?

I'm using the Gigabyte GA-X87Z-UD4H with the latest (none beta) BIOs version (9F).

 

I can try to upload some pictures from the UEFI if you want me to, but they will be taken with my phone (or is there a way to take a screen shot out of the UEFI that I don't know of..?)

 

Thanks in advance.

Hello kermit,

Maybe you should try only ocing the cpu first? I have no idea how gigabyte UEFI works 1.29V should do no harm i have my i5 3570K with an asrock mobo at around 1.26-27 or something stable also really easy to oc sorry this may not help you but you could also try a lower cpu speed at lower voltage if you want to keep your cpu for maybe sometime longer.

 

[KermitFTW]

I didn't OC anything else, the changes I've made to my RAM were only to make sure they stay at stock speed.

Seems pretty normal to me -- you just need more voltage. go up to 1.35V see if that helps.

please do remember that safe voltage is different depending on architecture and finfet (22nm in this case i think)

consider that haswell chips were refreshed with devils canyon because they had shit TMI your temp wouldn't be so high otherwise

Right now I have no crashes with 1.29V at 4.4GHz, I'll try to stress test it for 8 hours with that settings, I don't wanna go over 1.3V at this point...

He could try this and get the best out of the cpu before he replaces it but 1.35 doesn,t really sound that safe first try 1.3V or something.

Ah, misread the post.

so yeah, seems like you're good to go for the 8 hour test, although don't be surprised if it crashes and you need a bit more: 1.3V or 1.31V.

your temps are fine anyway, and it won't kill the CPU at under 1.35, so you're golden.

1.35V is considered the safe limit for CPUs

realistically it won't die under or at that voltage.

[KermitFTW]

The main question here is, am I missing anything here?

Did I forget to do something or have I done something wrong?

Because if I've done everything right and that's what my CPU can do, I can live with that..

I just wanna be sure I'm not messing up anything here..

So trying to de-lid it will be be better for temps I take it, but what will I use instead of the stock? All I have on hand right now is the silver 5, will that do the job?

pretty much any good thermal paste is better than the stock. liquid metal is what they show giving the best results but it's also harder to apply it's conductive and you have to come back and do it every 3 months. which is also why intel puts what they do

[KermitFTW]

If I'll be using the Silver 5, how often should I reapply it? and on the CPU cooler as well... I think I haven't done that in about 3 years now..

My 4670k was an absolute voltage pig to hit anything over 4.4. I think I was cruising along around 1.36 or so to keep it at 4.6GHz as a daily overclock for about two years straight.

 

I'm not sure where the arbitrary "max safe voltage for Haswell is 1.35v" came from but in my experience with a whole variety of K series Haswell chips; both regular and Devil's Canyon, I can honestly say they can take an absolute ton of punishment if you keep the temperatures in check. Intel's own spec sheets list maximum voltages as being 1.6v (IIRC, I'll have to check again, I know maximum VccIN is 1.9v for sure) which seems ridiculous, I can barely keep my 4790k from throttling at 5GHz/1.45v and that's with a hefty custom loop.

 

Anyway my point is: If you can't go faster than 4.4GHz at 1.29v, don't feel bad. Most 4670k chips were annoying to clock up into 4.5+ territory.

Sure, I will be happy with a 4.4 OC, and as for temps, 1.30 and 1.29 both peaked at 75C, so I'll try to see if I can get some more juice out of my CPU on those voltages, maybe I'll manage to pull a 4.5 on 1.30.. Hopefully..  

 

BTW, is there a good way to see how much wattage my system is pulling, without any additional hardware..?

Overall wattage, no I don't think so, not without a Kill-O-Watt or similar. But some hardware monitors like HWInfo64 can show you the wattage of certain components like your CPU and GPU.

[KermitFTW]

The thing is that I have a 650 watt PSU, and along side the 4760K I have 3 HDD's, 1 SSD, a 1080 Ti and 1 LED strip..

You think I have enough head room..?

You're getting there with that 1080 Ti. You're likely hitting around 450-500W under heavy load if I had to guess. A power supply calculator (like this one) will give you a baseline idea of what your system will use. They're not 100% accurate and they tend to over-calculate to compensate for accuracy so keep that in mind.

Screw that, tried running FurMark stress test with this OC, got a BSOD... Probably PSU related since that calculator you gave me said I will need about 662 watts, with a recommended PSU of 850 watts.. And without the CPU OC it sais it pulls 632 watts...

 

Or can it be an unstable OC..?

Could be unstable, but I'd say you're more likely due for a PSU upgrade.

[KermitFTW]

I'll try to get a 850w PSU with Corsair Link compatibility, since it has the wattage monitoring feature along side all the neat Link stuff, probably the Corsair 850w 80+ gold rm850i, which seems to be more than enough to be future proff, for when I'll get a new CPU....

 

On that note, since my CPU is kinda old, I'm planning on getting a new CPU in the near year, a 850W PSU will be solid one for this?

I'm sorry, but when it comes to PSUs and power consumption I'm totally lost..
