i7 4790k overclocking

[gepowr]

So i had a profile in my bios for a while now, i just want to tweak it a bit more. At first: Are my voltages and temperatures generally alright here ? (i7 4790k 4.5GHz fixed, cooler: Scythe Mugen 5)

 

 

I've been running the intel xtu stress test for 10 minutes and followed that up with 30minutes in a cpu intensive game (battlefield 1). Everything has been perfectly stable so far. Tomorrow i will try to lower my core voltage further down, but what about the cache voltage ? Should i just leave it at 1.150V? I basically just want a stable and tweaked "performance" profile in my bios, so i could just simply switch to it when i need more cpu performance. I ran these settings without any c-states from intel, aswell as a fixed core voltage of 1.200V. I know this has been asked a lot in many different forums but is it okay to run a fixed voltage on a daily basis ?

Run with an adaptive core voltage to allow it to drop voltage during low load situations, while nothing is wrong with using a fixed voltage just no point on running as low as 2.0GHz at 1.2v. I wouldn't go past 1.35v on Haswell for 24/7. Keeping C states and all the power efficiency stuff will help keep haswell's power usage down to as low as what I saw as 40w on the CPU during gaming.

Cache voltage I wouldn't go past 1.2v for daily.

to test stability, I run Furmark+Prime95 overnight (6 hrs)

This is pretty much what I did with my 4770k.  I ran it at 1.2V and it was stable for 4.4Ghz which was good enough for me.  Test stability using a variety of stress tests/benchmarks (I typically ran a bunch of IntelBurn and then some Cinebench and 3DMark).  65C is plenty cool to be running all the time.

When I had my 4770k, I ran it at 4.7GHz at 1.22v, Cache at 4.6Ghz 1.15v, 1.9v VCCIN(CPU Input Voltage) and always tested stability with AVX. If it wasn't avx stable it wasn't stable enough for me.

Seems fine. I’d imagine you’d want to push it a bit more if applicable.

I would love to use adaptive voltage, however i don't really understand how to set that up. When using adaptive voltage isn't my mainboard applying an auto voltage to the cpu which i can then regulate down using an offset ? The offset applies to the load AND idle voltage right ? Wouldn't that make it unstable when it undervolts too much in idle ? On stock settings, the core voltage while single core boosting (stock single core 4.4GHz boost clock) jumps up to 1.267V which is pretty high imo since i achieved 4.5GHz on all cores with just 1.2V. Generally just not quiet sure how to set that up correctly.

I'll definitely try that once i got the time!

1.26 isn’t high at all. Same voltage i need for my bad 4770k to do anything 

 

Think I had the 4790k at 1.35 for 4.8. Don’t remember as I don’t run high oc’s anymore.

Well i'm talking about stock here. Considering it boosts only 1 core to 4.4GHz, 1.267V sound pretty high to me. Anyways, good to hear that my settings seem fine so far.

[Mick Naughty]

Well yea stock is always better to be safe than sorry. Only way you can sell a product like that. 

 

Like stated, could just put adaptive on with the max of 1.2. May be able to find a YouTube video of how to set that up.

That's a good idea! I will watch some youtube videos later and try to set that up. I will report back if i have any questions and or have molten my 4790k.

So i've tweaked it a little bit. I increased the multiplier to 46 and found 1.200V to be stable. I set adaptive core voltage which selects 1.267V without an offset. So i set an offset of -0.045V not (-0.050V wasn't stable). I enabled the C-states and the speedstep technology. Should i leave the cache voltage on fixed 1.150V as it is right now ? Or could i change that back to auto? 4.6GHz at 1.223V (due to adaptive - offset) is pretty good right ? I just got a score of 918 in cinebench r15! (188 single core)

I'm less commenting on your post as I am asking a question about this. I'm overclocking for the first time with this same cpu but am running into many difficulties. At 1.25 V and a a core multiplier of 44, Prime95 tends to run fine, but very very hot. The temperature stays around 100 degrees Celsius on all cores and doesn't vary much. At idle, the temperature is around the low 50s. Is this normal for a stress test? I've heard under load it shouldn't go above 85 degrees. Do you have any recommendations on how to go about overclocking on an asus board, from the beginning of the process? What kinds of programs should I use to stress test and monitor my cpu?

Cooler may be the issue. I use prime and cpu-z for testing. Cpu-z, real temp and asus suite for monitoring. Think my 4790k was at 1.32 @ 4.8 still hitting 90’s but I don’t care about temps for synthetics.

I've got a great AIO so I wouldn't think it would be an issue. I ordered new coolant and some compressed air so I can clean the radiator and replace the now 2 year old coolant. How long should a stress test be able to run if stable. Indefinitely? 10 minutes? I hear people say they run it overnight but which stress tests would these be? Any time my cpu stress tests for more than 10 minutes, either it freezes (most likely from thermal throttling) or it blue screens (which is probably just my lack of experience overclocking)

Well the cooler isn’t that great then. 

Depends on the test. Prime needs a certain amount of time to go though all the tests. I do 30 mins normally. Then see how it holds after gaming for several hours.

Maybe I'll see how low I can get the voltage at a small overclock (like a 44 or 45 multiplier) to see if I can get the thermal throttling under control. That way Prime will have more time to run its tests and I'll get a better reading

Cpu-z has a stress option. Give that a try and see if its hitting the same temps.
