Regarding my 4770k overclock

[AsianTechGuy]

Hello all I got my 4770k to overclock to 4.4GHz with 3.9 Ghz Cache Ratio with a Vcore of 1.250 and Cache Ratio Vcore of 1.200 and have a idle temp around 40-43 C with a ambient temp of around 26 C. It seems a bit high but eehh I don't have that great of a air cooler, which is the CNPS10X Peforma with Push/Pull Thermaltake fans. Before I couldn't even run AIDA64 stress test for 5 minutes on 4.4GHz. Now, Idk what I did different, but it runs the stress test for 5min fine now and temps are around 75-87 C , once in awhile it will reach in the low 90s but cgoes down quickly back to 75-87 C. Same for Intel Extreme Tuning Utility stress test ran okay for 5 min and same temps. But when I tried intelburntest on high for 10 runs the temps would skyrocket towards 90-100 C after a few seconds after start up. Is that normal or is something wrong because stress test from Aida64 and Intel ETU where in the 75-87 C with spikes to the low 90s time to time but not long enough to show throttling. Also yeah 5 minutes isn't long enough to say a overclock is stable but before I couldn't even stress test it for that long since either the comp would freeze or bsod so for now 5 minutes it is for me. Just seeing what my processor can do to find that sweet spot and then stress test for a couple hours.

Only use the intel IETU to stress test. dont bother running any other stress tests unless you want to generate heat. the IETU is the best stability test for haswell

 

try this

 

make sure you are on the latest official bios for your board.

 

clear cmos and load optimized bios defaults

 

restart and boot back into the bios

 

change your multiplier to 44 and your vcore voltage to 1.22V

 

set your ram at 1333MHz and manually input the stock voltage for your ram ( if your ram calls for 1.35V i would set it at 1.5V to start)

 

leave all other settings, dont change anything else.

 

try to boot and stress test with the ietu

 

 

 

 

 

edit try 1.22V

[AsianTechGuy]

Tried 1.22 and bsod as the stress test started up. Think I will try to work my way down from 1.250 when I have free time. Hopefully I can get 4.4 GHz at least and thanks for the reply. Also is it normal for the temps to jump to 90-100 C on Intelburntest on high for 10 runs in a few seconds?

ya thats normal intel burn test is NOT validated for haswell cpu chips.. just dont run ibt unless you need to keep your room warm in the winter.

 

starting at 1.25V and working your way down is also a great idea. make sure you set your ram at 1333 and 1.5V this is soo important. you have to isolate your memory as best you can.

Thanks for the fast replies.

i crashed bsod after 3 hours at 1.22V

 

i am now trying 1.23V

[ProKoN]

doing what i mentioned before i was able to achieve 4.4GHz stable for ten hours at 1.23V

 

you may need more or less volts (+ or - .04V) to achieve this but i think its entirely possible

Well the other night I had set my Vcore to 1.2370 in UEFI and was able to run Intel ETU for 30 minutes and under the Vcore in IETU it said 1.2380 so yeah I believe that maybe the sweet spot Vcore for my chip to hit 4.4 GHz. Might try 1.23V - 1.2370 and see where its stable if I have time today.

you need to be able to run the ietu for 8 hours or more

 

once you get to 8 hours stable we work on bringing the ring bus frequency up

 

last step is memory.

Well I tried 1.23 and 1.237 and BSODs on a 1 hour Stress Test for IETU (around the 10-20 minute mark) then I tried 1.250 and it ran for the full 1 hours (not going to run stress test for 8 hours+ until after my summer school ends, which is in about 2 weeks) but for now I just wanted to have a basic idea of what my chip can do so when I really have the time to overclock I have a good idea of where to start. In about 2 weeks I will try to run my CPU under 1.250V at 4.4 GHz with a cache ratio of 3.9GHz for 8 hours+ and either report back to this thread if I have problems or am successful in my overclock or start a new thread. So for now I shall be running at stock and have saved the 4.4GHz overclock settings in my UEFI.

kool

 

sounds like your going to need

 

1.24V

1.25V

1.26V

 

in that area to find stability

 

i got mine stable for 20 hours @ 1.23V

 

I just brought the ring bus up to a 1:1 ratio @ 4400MHz

 

cpu ring voltage @ 1.23V

 

if im stable for 20 hours i will work on bringing  the ring voltage down

 

if im not stable i will drop the ring bus untill i find stability, then begin to drop the ring voltage after.

I hope this is not "thread necroing" since its been about 2 weeks since any activity and I didn't want to start a new thread just to post my results.

So well yeah I tried 1.25-1.26 and I would BSOD on a 8 hour stress test on IETU, so I tried 1.275 V and on IETU it reports it at 1.2780 V and the max temp on one core was 92 C and an average temp of 85 C overall with an ambient temp of 25-26 C and it passed the 8 hour stress test. So I feel for now it's alright, the temps are a bit high and when the temperature around where I live lowers a bit more I will try to go for maybe 4.5 GHz. For now I just hope I can lower my Core Voltage a little bit because I want to have the lowest voltage I can get with a stable 4.4 GHz over clock.

Keep all your overclocking posts for in this thread, for it is a great way for you to reference in the future

 

sounds like you found some stability @ 4.4GHz. Would be nice to get your voltage lower, since your ambient temps seem pretty hot

 

Temps are pushing the upper thresh-hold, but are fine if you don't exceed 90c.

 

I always suggest saving up and buying a top notch cooler.

 

Haswell cpus demand "great" cooling

 

I really suggest going with a top rated AIO liquid cooling solution

 

The swiftech H220 is still my personal favorite.

 

what s you ring bus set at? 3900Mhz?

Well hopefully during the Fall and Winter my ambient temps lower.

 

The average temp of my CPU doesn't exceed 90 C but sometimes goes to 90-92 C and goes back down and my hottest core reaches 90-92 C at 4.4 GHz with 1.275 vcore. I've tried 1.270 and it BSODs so it seems I need 1.275 vcore for stability at 4.4 GHz. So for now I will run at stock and try again when the weather is a bit more chillier.

 

Yeah I would like to get a H220 but with them not selling in the US anymore its kind of hard to find. I am thinking about the H100i in the future but then my case becomes a problem, which is the Z11 Plus by Zalman. Well not a big problem just got to mod the top to fit the rad and 2 fans. But I find that my Zalman CNPS10X with 2 Thermaltake fans is fine for running at stock at the moment. Currently trying to save up for a good GPU, SSD, and new hard drive then a AIO solution, hopefully a new rendition of the H220 is out by then that will be sold in the US or something better.

 

Yeah my Ring Bus/Cache is at 3900 MHz with a ring voltage/cache voltage of 1.200.
