2500k+Maximus IV

[Seithan]

Hello, im trying to overclock the cpu but keep low temperatures in the trade.

Target frequency is at 4.2k

Its stable with 1.18v

Though in HWINFO i get a reading of " Core # VID: 1.366V"


Is there a way to decrease that voltage? Why it doesnt show as 1.18v as its set in the motherboard?

Any tips to keep the overclock stable with manual settings to decrease the heat?

Thanx in advance!

What you see is the VID.. Vcore and, VID are two different stuffs..

VID is what the CPU is asking/ telling it needs.. This is generally set by Intel for each chipset. So, you won't be able to change it manually..

Vcore however, is your actual voltage.. This is some thing you can manage maually..

Can you please specify your system (including cooler, PSU) and, what technique you are using to OC?

Regarding temps and, voltages, any temps < 75C during max stress (genrally this won't happen in your daily usage, however, it depends on your cooler), is fine for long run.. 🙂 Any voltage below 1.45V is good to go for long run..

Though, it is advisable to keep both of them as low as possible. Also, when you say it is stable with 1.18V, do you mean at 4.2Ghz or, normal stock settings?

Please do over clocking one step at a time. You will get an idea how your chip behaves. Understand your system and, you will know yourself how to decrease the temps and, voltages along with having a stable overclock.. 🙂

Njoy your OC..

Cheers,

chip looks stable on 30mins Prime95 and on gaming DX11 games.

4.2k @ 1.18v

I have disabled PLL, trying to remove boosting voltage and make it run cooler. Im not really sure what to tweek at all, just the vcore but i want it as cool as possible.

PSU is 750 Thermaltake Toughpower along with PushPull fans at 2.5Kish and 3x case fans @ 1900sh Kish (those are adjustable, they kick max power at 40c Mobo temperature).

Im hitting temperatures closing to 70c and idles at 35c+

What is your room temperature during this prime95 run? I am not aware of the iv extreme's (I assume!) BIOS menus. Well, if you are not sure on what to change, post your BIOS snapshot here. To take a snapshot/screenshot of the BIOS, just plug in a Fat32 formatted USB and, you can save the screenshots in them by clicking F12. I can guide you through it on what changes to make. This can help others looking for the same too. Also, what is the CPU cooler you are using?

Basics of OC Manual mode, what to change:
1. Multipier,
2. CPU voltage (start off with your current 1.18V and, keep decreasing by 0.005V),
3. Keep Digi+ VRM/ Power Control-> VcoreLLC to 25%/Regular
4. Make sure Intel speed step is enabled and, your system is set to power saving mode in windows.

Also, please mention in detail your configuration. Maximus IV gene or extreme?

Just to give you a heads up, go through this: http://rog.asus.com/194232013/overclocking/overclocking-guide-4-7ghz-core-i7-3770k-on-the-maximus-v-... It should be the same for your cpu too (the basics at least) 🙂

And, one very important thing to remember, do not over clock until you have gone through as many over clocking guides as possible.. This will save you from a lot of unwanted tensions.. 🙂

Cheers guys!

Mobo is Gen not Xtreme. i think i can change by 0.05 increments though only

What cooler are you using?

Hyper TX3+ P/P configuration (2600Push/2200Pull)

Those temps are consistent with that cooler.

What would you upgrade to?

edit:
Cooler Master Hyper 212 looks quite nice and capable. The difference in the "plus" edition is that it comes with an added fan?
