Deliding a 4770K (Haswell). Improving temperatures and maximizing overclockablity. - Page 23

Here's some info from some Asus Motherboard Guides. They are all pretty similar.

CPU Integrated Fault Management - Disable to prevent tripping the FIVR when overvolting

CPU Core Voltage
CPU Cache Voltage - by default, takes the standard CPU voltage - increase with Ring/Core frequency
SVID Support - Enabled for Overclocking
SVID Voltage Override - Defaults to cpu standard voltage - increase with Core frequency

Yeah, it looks like what it's showing in the manual for that board.

Reading a few of the Motherboard Manuals for different manufacturers, here's my best guess for getting more out of these chips.

CPU Integrated Fault Management - Disable
VCCIN - seems similar to CPU PLL and can possibly be lowered to reduce thermals
CPU Core Voltage - increase to increase CPU frequency (very small increments, over volting is bad)
CPU Cache Voltage - increase with Ring/Core Frequency. can be greater/less than core voltage depending on cache quality.
SVID Support - Enabled
SVID Voltage Override - Set equal to core voltage - unclear whether it can be greater/less than core voltage.

Due to the IVR's ability to fine tune different components of the CPU. When you encounter instability, you should increase the voltages of each component individually.

i.e. start with all stock voltages (not auto - manually input the voltages) and increase the turbo multiplier until you fail stability.
increase just the core voltage and try again. if that fails, then set core voltage back to stock and increase the cache voltage and so on. if you can't find stability, then increase them all the same amount.

Being able to fine tune the cpu to this degree seems like and OCers dream. Seems you can gain stability for each component without increasing thermals for the entire CPU.

You may wanna sell it in warranty before opening it up and then selling it for a new one as it may sell better that way, even though you'd be doing the buyer a huge favor. Dam Haswell gets real toasty.

Yeah it's a crap clocker... Might wait a while for some decent batches to start showing up before I buy another one.
Too late on the waiting part lol, popped it open at work today smile.gif
Took all of 20 seconds including chucking it in the vice and two little love taps and it was over, Couldn't of gone any better if I tried.
Even with just mx-4 under the hood still dropped almost 20'C thumb.gif
Brings my temp spikes to ~75' instead of ~92' even with an absolutely horrible cpu mount.

Hi, just registered to share my results with you guys biggrin.gif
First of all, I have a 4670k and ASRock Z87 Extreme3, cooling it with an HR-02 Macho Rev. A
Currently I'm running at following settings:

BCLK: 100 MHz
Core Ratio: 42
Cache Ratio: 38
Core Voltage: 1.200V (Adaptive Mode for undervolting when idle, but it overvolts automatically to 1.250 when AVX is used for LinX and such)
Cache Voltage: 1.150V (Adaptive Mode)
Vccin: 1.700 (just testing, if it reduces power consumption)

I haven't delid it yet, I'm pretty afraid of it breaking.

So, my experience so far was, that if I push the Cache Ratio too far or I don't give it enough voltage, it'll freeze when LinXing.
However, if I do the same with the core, it'll spit out a BSOD with the message "WHEA_UNCORRECTABLE_ERROR".
The program, which shows my voltages perfectly, is HWiNFO64, but is there any way to see the Cache voltage?
I haven't played with the other voltages yet, and the ASRock UEFI seems a bit crappy this time, if I type in a voltage of 1.100V for a multi of 40, it will just give 1.150V... can't set anything below that, it's always 1.150V, if I use Adaptive Mode. Offsets can't be manual negative (sorry, I was tired ^^), and in Override Mode it will not undervolt when idle, so that sucks too.

I think I'm going to try overvolting the Vccin son and see if that makes a difference, since I can only get to 4.3 GHz with a lot more voltage than 4.2, seems like the sweet spot on this sample, but I was hoping for a bit more clock.

undervolting incorrectly can kill the chip too.
be careful.
post #225 of 1134
Yeah, I've read that Vccin should always be around 400 mv higher than Vcore. But lowering Vccin does not really grant any great benefits, so I think I'm going to try the other way now.

And something I forgot: If I change the multi to anything above 34 and then disable Turbo Boost and EIST, it will just stick to 3,4 GHz, although CPU-Z states e.g. "3400 MHz(8-40)". I guess this is a bug in the UEFI, but overclocking with the Turbo is just as good.

I overclock with the Turbo or have in the past.. smile.gif

My 4770k to OC pretty well. Batch L307B240.

Define R4 case w/ 2 stock fan frontal intakes, Phanteks PH-F140TS back exhaust, D14 heatsink (though I'm RMAing because the fans are unusually loud. Constant ticking noise in both fans regardless of RPM that is audible ~1.5 feet away).

4.4GHz @ 1.22v. Haven't had time to OC further but I'm pretty sure it'd go down to 1.21 / 1.215v, just haven't bothered testing yet. Unstable at 1.2v though at 4.4GHz. Asus Suite was able to take it to 4.7GHz until it crashed at 4.8GHz, but I'm not sure on the voltage nor the heat. Also have a 44x cache ratio by the way. Using an Asus Z87 Pro.

Heat on the other hand is pretty ridiculous considering I'm used to temps of my old E7400. Hitting ~86C max in Prime95. Going to reseat to see if they drop as I think there might've been a few air pockets since I was having trouble installing it. Under normal usage it idles at ~35~40C. Playing games it usually hits a max of like 50C since I don't play the latest atm, so not really a problem. Usually play CS:GO or LoL.

I'd say it's pretty good though for a silence-oriented case with only 3 intake/exhaust fans and 2 GTX 260s in SLI smile.gif

I might delid soon just to get into a more comfortable temperature range, though I'll be using the MX-4 since I don't want to wait for the CoolLaboratory ones. And I found out (by testing it on my E7400) that the double sided razors (http://www.amazon.com/s/dp/B000JPMHWK/) make it extremely easy due to how thin they are. They're thin enough you can literally bend them without any force and I unknowingly slightly cut my index finger by just testing to see how sharp it is (I didn't bleed nor did I feel a thing). Not much force was required for the E7400 either; I was just sliding it back and forth and it was cutting through. Not sure if I want to void my warranty either way though.

A vice and a hammer and a piece of wood and you can watch those temperatures plummet to the ground.

AyeVeeN, do you have the same voltages for the cache as for the RAM or do you have it on Auto, or what have you set it to?
post #230 of 1134
@Cyclops

or the double sided razor smile.gif Just updated my post with it. I may do it soon, just need to get over the fact that I won't have any warranty. I honestly can't trust myself with a hammer with something that delicate.

@ratchet285

My cache voltage is 1.275v (I didn't change it at all), RAM is at 1.35v (Ballistix Tactical LVP/LV, 2x8GB).

Other voltages (I left everything else stock, I'll probably screw around more / learn when summer starts) are

CPU Input: 1.79v
PCH Core: 1.05v
VTTDDR: .675v
PCHVLX: 1.5v

I don't even know what those are for in all honesty.
