4770k h100i and a g1 sniper z87

atomic7431 · 28 Nov 2013 at 10:52

ok want to check my temps and see where i can go with this setup in terms of stable oc and reasonable temps.

so i have set the h100i fans to performance mode
gone to 45 on the multiplier
and have set a 1.260 voltage core

temps are as follows -

seems a little high for my liking, can i reduce the voltage core further or will the oc become unstable i wonder...

core 0 and core 3 have 9 degree difference, wonder i f i need to reseat the cooler

ok set it too 1.240 voltage core and getting the following -

atomic7431 · 28 Nov 2013 at 11:26

1.230 voltage

as much as i dont want to still think i may try reseating cooler as big temp difference across the cores

Yes it shouldn't be THAT high in performance mode in that voltage. Did you touch any other volts? Cause you motherboard might ramp up VRIN or VRING if they're left on auto; causing huge temps.

Either reseat or tighten it a bit, that's too high even for IBT.

That said, IBT is a bad test for haswell. Just use AIDA64 or use the machine.

My H100i does under that at 1.295v (Vring 1.14) at silent mode.. though my airflow is great.

not touched anything else, what volts is a good place to start for VRIN or VRING?

thanks

This is a great place to start for all voltages

Take an hour and read it; overclocking is easier when you understand the background a little bit.

just been reading that lol

changed some settings and disabled c1e, c3, c6/c7 and eist

aida64 temps as follows -

will test some games etc and see where the temps are at.

That a good overclock, not everyone is getting 4.5GHz from their chips.

atomic7431 · 2 Dec 2013 at 10:51

Thanks, only just see your reply.

Its nice and stable, been using without issue for a few days now, idle temps are 30 to 33 across the 4 cores now, the temps have evened out a fair bit as there was a bigger margin between them.

Now just need to get a different cooler for my gpu as with no oc the card is still hitting 93 with stock cooler and fan set to auto which hits about 50% can tun this up via afterbutner but it becomes very audible.

Is it a radeon R9 290 or 290x?

That temp is normal for them. Otherwise, it's very very high and could indicate an airflow problem?

atomic7431 · 2 Dec 2013 at 11:13

its a vtx 290 unlocked to 290x and thought the cut off was 95?

Replace the Corsair fans of the H100 with 4 Apache or Magma.
The corsairs are too loud and providing not enough pressure to cool properly.

You can do better job while you do not get deaf.

Second, decide how much performance you need more and pop the lid replacing Intel ~~paste~~ cement with an MX4 or similar.
With your low voltage, you might be able to get 5Ghz from that chip, having at least 20-30C less on load.

My 4820K at 1.35v runs pretty cool at 4900 with the H100. Also IBT/Prime etc are crap and stopped taking them into consideration.

At 4900 they all fail my OC, but games do not crash even demanding ones like BF4, having it almost a week now.

Well the card is "designed" to run at 94c and throttles at 95c, but that's normal for the damn things. Only way to improve it is to have a perfect case airflow (a few C difference) or cut bigger holes at the back of the card (Void warranty).

It is what it is, the cooler is ****.

I'm using an Asus Maximus VI Hero, 4770K, Kraken X60, NZXT Phantom 530 case with 1.34 volts. I get 4.5GHZ, my temps hit 80-85c with Prime95. Idle 30-34c.

Jester* · 3 Dec 2013 at 06:54

It is strange reading this after just spending last night on my first attempts at overclocking, as I now understand what all of this means haha!

So far I am at 4.4 GHZ @ 1.3 VCore, 2V VRIN Override, Ring Voltage 1.2V . Spec is in my sig below and a quick run of AIDA this morning I was in the 75 - 80c temp range. My H100i's are in quiet mode.

Tempted to push for more, but I am going to run a few more tests to make sure it is stable and running within the recommended temps.

Thanks for the thoughts, looked at the fans and the Enermax Magma fans seem a good piece of kit as follows,

H100i fans

• Fan speed: 2700 RPM
• Fan airflow: 77 CFM
• Fan dBA: 37.68 dBA

Enermax Magma fans

• Speed-Adjust
• Flow (CFM): 69,15
• Flow (m³/h): 117,49
• Noise (dB(A)): 18

so a bit less airflow but way less noise.

atomic, I've got a similar system to you but with a h80i, tried reading the over clocking guides but getting confused with different terminologies and how the gigabyte describes it. Is their any chance and telling me exactly what changes you made in which sections of the bios. Also if anybody from overclockers is reading this do you have any open days to go though the basics of overclocking (I'm definitely not ready for deluding yet)

cheers

Ok im no expert either just read a lot what other had done and tried it from there. so the following is what i have now done so far-

ok so under Performance and then Frequency i changed the following -
CPU CLock ratio from 35 to 45
Extreme memory profile(x.m.p) to profile 1 (to use all my 1600mhz ram speed)

Then just above the extreme memory profile you can see on my bios it says Advanced CPU Core Settings.
In here i changed the following -
Uncore Ratio to 43 (could not match the same clock speed of 45)

then at the bottom of the same menu (Advanced CPU core settings) i Disabled the following -

CPU Enhanced halt C1E
C3 State Support
C6/C7 State Support
CPU Eist Funtion

I also went into Voltage CPU Core Voltage and changed the following -

CPU Vrin Loadline calibration to turbo
CPU Vrin External Overide to 1.900v
CPU Vcore 1.248v
CPU Ring Voltage 1.160v

the pic shows a slightly lower vcore and cpu ring voltage, i upped them as it made the response in windows a lot more snappy.

now depending on how your chip performs and system cooling etc may effect how far you can push your system, but hope these settings give you a good start and sorry for some of the pics being a little poor

Set a custom fan curve will help with temps a lot

thanks atomic, I will have a go and see how many blue screens I can get
