Pimp the Haswell i5-4670K to 4GHz - Page 2

--Like these guys here, seems to be just messing with the CPU voltage:

http://www.xbitlabs.com/articles/cpu/display/core-i5-4670k-4670-4570-4430_8.html#sect0


And what is bad about prime95? I have been reading you just need to use 27.9 or earlier for Haswell. True or false?

I am not interested in finetuning the volt(s) down to the smallest tiny percentage, just to be able to get 3c lower, and voltages 1.130 vs 1.134 (bad example but still) I dont care.

4Ghz is needed. It is not a world record. Is it not possible to achieve it plain and simple, without having to mess with serval things at once?
I was hoping for a all voltages on auto (and editing the cpu voltage as the max) then stress test for 4 hours (yeah I know someone will probably say 24hours, I just dont want that) Then if no errors, call it a day. Overclocking is not an hobby of my. And because of that, that is why the goal is only 4GHz.
well here is the kicker haswell can be very finicky about voltage it is super sensitive just a hair to much voltage will cause stability issues and same for 2 low haswell is a mixed bag when they put the CPU voltage regulation on the CPU chip itself well chaos was the outcome luckily they learned this and skylake has this back on the motherboard as it should be.

I will state this haswell has a very picky voltage situation so you will need to fine tune it whether you want to or not unless you like corrupted data or BSOD's or occasional momentary freezes / lockups. I can only say one thing haswell was never designed for OCing it was designed for laptops and mobile devices not enthusiasts especially one that wants to set it and forget it Haswell is like a fine woman you need to wine and dine her first before you take her to bed.

If you are testing for stability, I would go with the stress test.

Well I am testting for stability? The goal is to take the 4670k to 4Ghz, and then stop there.
And any thoughts on the selected memory on the stresstest? I tryed to google it, but there are not alot of results. And most doesnt cover it.

So the plan is:
1) Disable Turbo boost

2) Set CPU Clock ratio (or is it Uncore ratio?) to 40

3) Try CPU voltage at 1.120 as a start

4) Run Realbench stresstest (not the benchmark stuff)

5) if RealBench fails, then increase to 1.13v And then increase to 1.14v and upwards from there, if RealBench still fails.

6) Proceed untill RealBench doesnt crash

7) Then play some long hour gaming over some days


Yes?

That would be the idea. thumb.gif If your voltage is to low you will most likely get a 0x0000124 error on your BSOD scree. If it is a different number google it or post it here and we will help you figure it out.

Its the CPU Clock ratio or Uncore ratio I need to mess with?

Core clock, but you should manually set the uncore ratio to 34.

Read the guide that i linked

I will read the guide, dont worry. I am about to hit the bed now. And friday I should beging overclocking (after having read your link)

But one question still remains about RealBench. I cannot find the answer when searching on google. Do I need to set the program to the amount of memory I got? I know the info says I shouldnt. But the few google results I found, one person said setting it to the amount you got installed, will stress out more.

So anybody got some inputs on RealBench memory setting?

It shouldn't be that important, the main test in realbench for stressing CPU core is x264 which barely uses any RAM

I am getting confussed about CPU Clock Ratio and Uncore Ratio now.

As I understand, Uncore Ratio is the CPU's cache's clock speed, and it is tied to the bus frequency. I just want to overclock the CPU. So CPU clock ratio is the only one I need to mess with, and then as suggested keep Uncore Ratio at 34 (which I assume is default)?

If you are going for minimum voltage, you may be stable with a few mV less VCore using a lower cache. That being said, no you dont need to mess with it if you don't want. Core is king.
