Intel God's "Quick & Dirty" OC Guide to 4.4Ghz with Haswell

[nagasama]

I definitely hit the lotto and got a good chip.
right now testing 4.8 @ 1.235 vcore. vccin @ 1.8, ring ratio is 35.
temps absolutely acceptable at 59-64C coolest/hottest (using H90 in HAF932 case)
4.7 is rock solid (12hr+ aida64/XTU stable) at these settings. I think I will likely have to go up to 1.255-1.275 to stabilize 4.8/4.9, but maybe not. Temps should remain acceptable even at those voltages and put this chip up with the best of the best. I can dig it.
If this thing does 5ghz at/under 1.3 vcore i am gonna TRIP.

 

[nagasama]

What do you guys think about ASRock's optimized OC presets? I'm getting rock-solid stability with them - i5-4670K @ 4.4 GHz, temps max 70c per core. Tflops only at 63 per test atm, but I must try nagasama's tip and install SP1.

Are these presets safe, or do they have the bad habit of skyrocketing the voltages to insane amounts?

SP1 will solve the problem, I am almost certain.

 

[dddez]

They don't necessarily rocket to insane amounts, only if you let them do automatic testing. But a regular preset would only overvolt some over what you actually need.

With the preset, Vcore is around 1.160v @ 4.2GHz full-load. Could it be any lower?

What does the cache ratio do? It's set to auto. Should I touch it?

 

[nagasama]

im wondering if i need to change my ring voltage. want to do some other tweaking before i simply keep pumping more vcore to it. I know there are other settings to fine tune. wont pass aida64 at 4.8 with 4.7 stable settings.
settings are above, any ideas?

 

[gairleog]

Have you tried getting the CPU cache to 40-44. Might increase performance by a bit.
Also what OS are you using.
Also full system specs might help.

Yes, I was at 40 but qould get blue screen during stress test and I wasn't sure about which voltages to raise or what to do so I am now back to 35:

CPU RATIO 44
CPU CACHE RATIO 35

CPU INPUT VOLTAGE 1.900
CPU VCORE VOLTAGE 1.250

CPU CACHE OVERRIDE VOLTAGE 1.200

Hi, completely noob here. trying to follow this guide. I have the asus mobo, and get confused with some terms i can't see in the uefi.
Vcore is the CPU core voltage right? and when i set to apdative mode, few addition slot opens up so do i type my voltage into the "CPU core offset" or "Additional Turbo mode cpu core voltage".
for "cpu cache multipier" do i change both min and max?
The "cpu cache voltage" do i set that to manual and then change it to 1.2?
"Vrin/cpu input voltage" i found has "Initial" and "Eventual" which do i change to 1.9?
Sorry if these question seem too basic, I really don't want to mess up.

I overclocked my i5-4670K to 4.4GHz with 1.200v. Run the Intel Burn Test 5x at standard than 10x at higher. No bluescreens or system reboot. Do you guys think that I should lower to 1.9v or this is just ok as it is now?

 

[DeltaRecon2552]

Look at your temps.

 

[Dizzll]

My system:
4.5 @1.3v temp:74 (stable) (42 idle)
4.7 @ 1.38 temp 78 (not stable at max testing but fine for gaming etc) (45 idle)
I can't even get 4.2 stable at 1.2v

I use a CM hypo 212+ cooler and my temps seem low for my volts. My buddy same chip, but uses a H100i and gets same temps as me at 1.35vcore?? Any thoughts?

Also, I read that I can push to 1.5 max vcore as long as temps are ok, is that true?

 

[Y0GI]

No, it is not true. You should not exceed 1.300 v. Vcore to reduce the possibility of damage to your CPU.

[DeltaRecon2552]

I'd keep it under 1.35v. As long as your temps are in the low 70s and your stable you pretty much done.

Here are my temps using Intel Burn Test: http://s4.postimg.org/55b1wzf8d/Stress_Test_AFTERstarttemps.png

here are my temps using AIDA64 Extreme: http://s23.postimg.org/mzzkzqduj/Stress_Testwith_AIDA64.png

 

[JAYFRESH1271]

I guess i have a bad chip mines takes 1.28v to get 4.3

 

[Dizzll]

Ok, Guess I'm in the middle range quality at 4.5 1.3v. I didn't notice any gain of 4.7 anyhow. I'm 65-100fps in every game maxxed anyhow. The only reason I even tried was for FSX... Thanks!

 

[JAYFRESH1271]

i am using mines for fsx too but i try to get it to at least 4.4 n nothing i pass intel burn test but then i get a blue screen on prime

 

[Dizzll]

Honestly if it runs IBT you're not gonna blue screen on FSX. Prime blue screens way after games range.

When i try to get to at least 4.4 i either get a blue screen on prime95 or sometimes i do not pass IBT but most of the times i pass IBT on high i think my chip is one of those that do not go over 4.3 n need more than 1.25 volts to get it to 4.3

I have a stock cooled i5-4670k. I let AI Suite III overclock it for me at first to start. It put it to 1.2 vcore and 4.2 ghz. It crashed about 10 minutes into PlanetSide 2. So I rebooted and put my Vcore to 1.21 with a deviation of 0.001. I now run PlanetSide on Ultra at over 70fps in combat and over 200 at the Warp Gate. I'm happy right were it is. I didn't torture test it. Just gaming. Temps never went over 50 c. Should I go further or just stay where I am?

How did ps2 get over 60fps? I have vsync forced off on my rig and the fps stills stays at 60

Hey guys I'm running a 4670k on an asus maximus vi hero board and cannot for the life of me seem to get my cpu stable past 4.3ghz
I'm fairly new to overclocking so I will take any advice

I set my
all core multiplier to 43
vcore to 1.3
vccin to 1.9
cache voltage to 1.2

cpu cooling = corsair h100i

I got it to run a stress test in aida64 for about an hour and a half then went to bed to let it go overnight and woke up to it restarted and the weird thing is my temps are relatively low...averaging around 65-70 under 100% on the test. So temps arent a problem and I don't really wanna up the voltages much more if I don't have to

ANY IDEAS? I'm stuck lol

I am on the same boat but i am using asrock z87 extreme 4 board i got mines to 4.3 on 1.28v VCCN 2.0 cache 1.2 can not pass 4.3

maybe we just have processors from a bad batch lol

Yeah i guess lol lol or i am not using the right setting either i pass IBT n then get a blue screen on prime95 or i fail IBT

 

[Roederbaby]

Just used this guide to throw it up at stable 4.4 GHz. I was being afraid, that I had a bad chip. Doesn't look like it.
Decent temps at max ~80 celsius, but averaging ~75-77 in Prime95 @ 100 cpu usage!

Thanks a bunch for this! You're the man!
