post #18991 of 19637
Guys, I don't wanna be a pain but don't you have a solution for my problem? It has crashed like three times in the past few days and I don't understand why.

I thought an overnight x264 test would be enough to prove stability but even if it passed that test (12 hours) the voltage is obviously not stable enough. Is there any other test I could run, or maybe I'm doing something wrong?

Prime95 isn't out of the question, it's just when I used it that one time my temps went up to 90C so I decided to stay away from it but maybe I could try it again with "personalized" settings?

#1 use low cache ratio and enough voltage, CHECK
#2 use stable RAM, hopefully CHECK
#3 passing x264 at some voltage doesn't mean it's stable at that but it helps you find where the limit for that ratio is in regards to voltage
#4 once you find for example my CPU, 1.20-1.21V Vcore stable at 4.5GHz in x264 you need to add a "safezone" in my case just like you I later ran into random Vcore related issues with Handbrake crashing that's why I also made Handbrake x264 and x265 test, and added +0.02V to my Vcore to 1.23V @ 4.5GHz. At minimum add +2.5% Vcore. And try running Handbrake, it's kind of more fickle to pass. Also CPUs settle down after some time and may need more Voltage, hence the bigger the safezone you add the less issues you will have down the road. There is a reason why the stock settings are "overvolted" it's so that the CPU runs stable all the time.

I have links in my signature and maybe newer version may be found from wizzie in Skylake thread.

Hey guys sorry to pester but I posted this in the delid club just wondering if anyone has had a similar issue?

Has anyone had issues with their FIVR causing instability due to heat? I'm still trying to get my 4670k stable at 4.8ghz+ but I get full on hard locks randomly while gaming. Not sure if it's heat related or voltage settings maybe, I did get it to pass a few stress tests at 4.9 but it crashed repeatedly while gaming, my Hyperx RAM might be to fault as they will not run with their XMP settings.

My ram will not run at their rated speeds, I've changed my ram but haven't done any tests yet due to redoing my custom loop in acrylic, would ram cause stability issues randomly like I've posted about above? How heavily does X264 use ram for stability? That might answer a few of my questions indeed.

Hi!

I got a I7 4770 (locked sadly) for 70USD, and thats a scoop!

Though, I managed to get it to 3700 all cores on stock settings/BCLK with my Z97 ann. from ASRock. If i upgrade to a MSI gaming 5, would i be able to do the same thing? I`ve read that haswell OC is locked on the newer bioses?

Please inform me. smile.gif

And, is it possible to get this stable 4000 with BCLK you think? Would like to test it, but the I3 cooler is no good, went up to 100¤C under cinebench redface.gif

The CPU will be paired with a 980Ti perhaps, so it`s important that it`s stable as I`m gonna use it to fold. smile.gif

Any cheap CPU coolers you recommend? The Bequiet Pure rock seems great, cheaper than the 212 evo as well.

Cryorig H7 universal, HR-02 Macho 140 which ever version you like there are many same cooler different fans and aesthetics. These are the two I would look for in EU. The HR-02 is often much cheaper than any other similar cooler which makes it a good deal, maybe shops getting rid of older stock, who knows but can be bought at decent prices all the time.

I have ASRock Z97 Ex4 and I'm not sure even the P1.00 UEFI supported locking all cores to max turbo on 4790. I think it's been disabled or not possible from the start either in UEFIs or microcode updates.
So you can only do BCLK up to about 105MHz, say you could 4050MHz on 4770 but probably can't lock them on max turbo which means my 4790 ran most of the time on 3-4core turbo ratio and almost never on 1-2 core turbo ratio, making it a 3.6-3.7GHz all the time.

Then i won`t switch mobo. I`m happy with 3700 on all cores without BCLK changing.

Will look out for those coolers, if not I`m getting a Beqiuet Pure rock.

Will test a bit with BCLK soon! Awesome to have som hardware to play around with that is not really needed. (In the same way as your main machine) :-D

Will report back when i get a good enough cooler. Long time since I was overclocking on the mainstream platform.

Why the heck won`t the CPU idle with only core OC?
And why the heck can`t i control the voltage? Goes up to 1.137. I want it to be under 1.000V. I set he 0.975V in bios, but still nothing happends. Can`t I adjust locked CPUs voltage?!?!

Motherboard is ASRock Z97 ann. edt with a single 4 pin.
post #18998 of 19637
Dunno, I can't remember much from the 4790 only had it when I started building my current PC for about a week, returned it got money back and ordered a cheaper 4690K instead as it was just released.
Override voltage should work and BCLK unless Intel blocked even voltage changes...

I only use fully manual/override voltage with C states and set offset to 0.001. This way you remove any automatic overvoltage. I use C states so the CPU can throttle down and goes to minimum clock and voltage as needed.

Hello fellow mellow clockers,

Here's some screens and info about my project overclocking the i5 4690k

hope this helps someone in their constant battle for higher clocks! thumb.gif

PC specs:

ASRock Z97 Pro4 Intel Z97 So.1150 Dual Channel DDR3

Intel Core i5 4690K 4x 3.50GHz So.1150 BOX

16GB (2x 4096MB) G.Skill RipJawsX DDR3-1600 DIMM CL9-9-9-24 Dual Kit <- 2 of those kits, 4 slots in use. (OC 2133mhz 12-12-12-30 t2 1.675V)

Corsair h100i V2 paired with noctuas pwm fans 120mm

MSI GTX 1070 FE OC (max boost 2025mhz, mem 9400mhz effective)

EVGA SuperNOVA G2 850w

Fractal Design Define R5 All fans switched to noctua. ( H100i v2 mounted on top, 2 moduvents removed)

Lian-Li PT-FN03 Fan controller (really useful, with this badboy and r5 default fan controller my pc is completely silent at idle and desktop use keeping the temps below 40C all time)

I started my overclocking project with Noctua NH-U12P SE2 cpu cooler and was able to achieve benching clocks 4.7ghz core and 4.4ghz cache with temps below 85C with vcore 1.260V and stable 24/7 clocks 4.5/4.5ghz 1.20vcore temps below 76C even under 12hour x264 stress run.

I wasn't happy with my 4.7ghz temps though, so i switched to liquid cooling (h100i v2) and was able to hit benching clocks core: 5.0ghz | cache: 4.5ghz with vcore 1.4v and cache 1.3v temps being under 85C. I stressed this setup 13hours x264 and 3 hours AIDA64 EXTREME.

Now for my 24/7 clocks, been using these for 2 weeks with no stability issues whatsoever. Core 4.8ghz | cache 4.5ghz, Vcore 1.320v Cache 1.230v VCCIN 2.0v LLC ON. Temps staying below 75C even under 13hours of stressing.

If someone is still updating the spdread sheet it would be awesome if my clocks could be added and validated there for rererence. If there is need for more pics or proof, i will be happy to deliver.


Now for the pictures

NIIIIIIIIICE!! Here'e what my golden 970 can do paired with a 4670k, that 1070 is a decent upgrade!
