Haswell Overclocking Guide [With Statistics] - Page 532

post #5311 of 19649
Yea 4770ks are very bad, the 4770ks are even more harder to pick, as in there is a greater chance of a bad chip rather than a good chip.

Got 4.4 on 1.25, and now trying 4.5 on 1.26. Failed after 5 minutes on AIDA64 so going 1.265.
This OC journey is gonna be a while...too much restarting and BSODs lol
After that I gotta learn how to get the Haswell power saving options that you mentioned earlier. Don't want 1.26 24/7 wink.gif

I find that OCing is quite intriguing, until you find your perfect clock and voltage, and your like, "my life is complete.)
Cant wait to delid AND water cool...

@kinzx If I'm not mistaken, if your chip likes to run hot, then you would benefit the most from delidding. Others please feel free to correct me.

Personally at my current settings ( 1.86VRIN, 1.265VID, 1.15 VRING, 45x/35x ) my load temps in CSGO, which is my heaviest regular usage, were ~66C, with the hottest core getting to 67C.

Otherwise, for Cinebench, it's about .... ~71C? I think my ambients are a little lower than usual.

@geogga I think the 4770k chips are easier to pick because I've been a much larger share of them do relatively higher overclocks at lower voltages.

As for BSODs, yeah, I had about 10-15 of them the day I got my 212X. Hilarious that I couldn't get anything stable until I got to what I'm at right now.

As for the ultra low voltage, I have all the power options set to auto in the BIOS, but C6/C7 to enabled. Everything at auto resulted in 800mhz @ .7v but after forcing C6/C7 on, it results in 800mhz @ .36v or less.

Just be careful that your PSU doesn't shutdown. I tested by leaving my rig idle for about 20 or 30 minutes ( had to modify my power options for that ) and then I tested with sleep/resume, and finally shutdown/restart. Since the PSU didn't shutdown and I didn't get any BSODs, I was good to go.

Here's what I got up to now.

Core Multiplier: 45x
Core VID: 1.32v
Vcore: 1.328-1.344
Uncore Multiplier: 35x
Uncore VID: 1.2v
Uncore Voltage: 1.22v
Input Voltage: 1.9v
LLC: Level 8 (Max)

Temps aren't bad, maxing at 72c in x264 and BF4.

I'm just wondering what else I should tweak and if this seems like a safe setup. Also, the only thing I can see that refers to VCCIN is lab led ad VCCIN Shadow Voltage, which is set to auto.

I have a 4670k and Maximus VI Gene for reference.

You can compare your batch results to the others ( batch number is on the box as well ), but it seems a little high for 45x. Then again, Darkwizzie is running his chip at 1.35v 46x. And mine is a little lower @ 1.265VID which is ~1.272-1.284 vcore.

I needed 1.32 to boot to 4.6 ghz and 1.36 to get 4.6 to pass benchmark and stress test. My hottest core get up to 81c-82c at 45 multi and 1.265 vcore, at 46 multi and 1.36 vcore I am hitting 94c-96c, this is running xtu bench and cinebench, at 47 multi I needed 1.365 to run cinebench and xtu spike but it to 100c. Even try and was able to boot at 48 multi and 1.375 but crash just surfing and watching youtube. Didn't bother upping vcore as I know that I will probably be needing close to 1.4 to get it stable but not going to until I can manage this heat. In gaming and my usual stuff my temp are in the mid 70c at most but stay around the 47c-65c range. I posted a pic of my temp going up to 60c doing nothing but just standing around in WoW with my 4.6 ghz setting.

It look like I will go custom water cool to see how much improvement in temp I can get there, and afterward decide if I will delid. I consider this a great chip if I can hit 4.7 ghz under 1.4 volt and a uber awesome chip if I can hit 4.8 around 1.4 volt if only for benching. It seem the chip has some potential but the heat on it is ridiculous. I think from all the posts I might have one of the hottest chip in the thread just at 1.265 volt.

Just to be clear, beside extensive test on 4.5 ghz at 1.265 vcore all the other multi were just quick test to get an idea so in no way am I claiming them to be stable. More test are needed.

On an unrelated but oc subject, looking at the XSPC raystorm, anyone has any thought on it. I will be checking and posting this question to the watercooling section.

Yeah, it doesn't seem like a very good chip, but as long as it hits 4.5ghz within my thermal window I'm okay with it. The other issue is that this is my first experience with OCing so I've left a few settings on auto. Also, I enabled C states, but the two options for C6 and C7 are short or long. C6 is set at short and C7 is set at long. Does this sound right? My voltage doesn't seem to be going down when idle though.

What kinda temps do you have from 1 cinebench run of a stable clock at like 1.2-1.3vcore? I usually take screenshots or note temps from 1 run, max temp on each core. If hyperthreading is on/off too

so i'd record like: core/uncore frequency, vcore/vrin/ring, max temp core 1, 2, 3, 4 (four numbers) and also ht on or ht off

I agree. If you can barely boot at a multiplier at 1.365 you are miles off from actual stability. I'd say there's no way you'll find rock solid stability under 1.45v.

The average is still the average: 4.55ghz. That's OK.

Not sure about that. You'll have to check the manual or the net. It was just a matter of auto, disabled or enabled for me. And use HWMonitor, HWInfo or something else to look at your Vcore readings when idle. Also check your Windows power profile ( If it's on high performance, it won't work ).. I'm usually in balanced, and works like a charm.

Under CPU Power Management Configuration in this place, you should find your answer.

Ah, thank you for the link! +1 for the effort and replies!

C6 and C7 are hibernate modes,C1E controls power steppings i think.I would'nt worry,when you dialed in final overclock set voltage back to adaptive,on my Asrock at least I set an over-ride voltage when stress testing then switch back to adaptive as it works to the maximum value I inputted in over-ride,unless stress testing or benching.I have C6 and C7 dis-abled as they cause excessive writes to SSD,my volts still lower when frequency does.thumb.gif
