Currently my 4770k is stable at the following:

Vcore: 1.25v
Multiplier: x45
Uncore: 35
Uncore voltage: auto
DRAM is at 1600 @ 1.65v
Eventual Input Voltage is @ 1.75

I tried to increase the multiplier to 46 increasing vcore slightly all the way up to 1.3v while increasing the eventual input voltage per the instructions accordingling (ended up being 1.8v for 1.3vcore)

It still would not complete a pass of h.264 encoding on Realbench, always BSOD. im running Win 8 so I get those lame uninformational BSOD screens.


So can some one point me to the light here? What should i try tweaking to get past 4.5Ghz, im coming to ocn because 1.25v stable is decent i think and to increase it .05 and still not gain a 100mhz seems odd. I could be completely off here idk thats why im asking.

Thanks guys.

Any questions about the rig its my sig rig "the sith lord" and its the Asus Maximus VI Formula (rig builder screwed it up)

I have to use ~1.24vcore set in bios for 4.5 to be solid.. yet 4.6 still isn't quite there yet @1.3. Don't stop raising it, but only IF you have to. Increase your Eventual input voltage to by 0.6 over vcore before you do that. 1.75 isn't enough, 1.85 might not be. You'll get to point (looks like you hit it to me) where it's just not high enough to support adding extra vcore and power draw and you have a black hole of just adding far too much of them for no reason (also set cache to 33x/1.15v til core is stable and where you want it.. but that one probably won't do anything noticeable)

So you've never checked an error message? Google them, learn which one is 101, 124 etc. 101 should be clock watchdog error. Get bluescreenview if it supports w8, take a look, re-check it if you didn't see a code etc.

Also, i prefer the x264 in OP - that package with an updated encoder (i manually updated it to 2389 ver by replacing x264-64 in the x264 package in OP with this file - download.videolan.org/pub/videolan/x264/binaries/win64/x264-r2389-956c8d8.exe - renamed to x264-64) is harder to pass and if you can't pass it, your encodes will start to fail a month or two from now when software like Handbrake and MeGUI grabs these. My MeGUI is still using ver ~2358, i think software in general hangs back a few versions, but they're updated quite regularly.

Don't throw too much voltage. If in doubt, set some stuff:

1600mhz or lower RAM

33x@1.15v uncore/cache/ring - NOT 34/35

1.85vrin, max or close to max llc

1.23vcore

All volts manual. If you can pass x264 at 3.7ghz (stock turbo speed) try 4.2, 4.4, 4.0 etc. Whatever, see what works with those volts without changing any of them - only changing core multiplier. Once you have a profile that is solid, you can work from there

What do you do once you get that solid profile? Up the voltage by 0.05 V and work to get a stable overclock from there? Something like that?

You can increase vcore as neccesary as you work up in 100mhz steps from having set 1.23vcore and finding something 100% solid - that way you can be careful not to add too much of voltages etc, and adjust stuff when neccesary; the 1.4v range is quite complicated and tricky to make work sometimes. The further away you get from ~1.1-1.2vcore, the more careful you have to be with adjusting other settings in general

Thanks for your help, most appreciated. thumb.gif I had gotten up to 4.0 which was solid and sort of 4.1 but bsod after the first x264 test (trying now and its passed 2/5)
I also had try upping the vcore close to 1.3 when i was testing 4.2 before 4.0 which also resulted in a bsod. Im using 1600mhz ram, so i could lower that and see?

I know this is haswell thread but do you guys suggest me swapping my 1600mhz to 2400mhz on my old sandy bridge setup? I know bf4 loves the faster memory.

Thanks for the info in op but i couldn't get my cpu stable above 4.3 and atually on 4.3 I was having crashes and blue screens. sometimes my pc tells me that something is not compatable when on my old mobo it was working fine. So Im just switching back cause i had bottleneck but not that much. I can wait for Mantle now smile.gif

The haswell even at 4.2 - 4.3Ghz should be equal to or faster than sandy at 4.8Ghz in low thread count apps. 4770k should kill the 2500k in multithread apps.
If swapping the 2400Mhz memory into the sandy rig it won't boot with higher than the 2133mhz strap so go with that, almost all SB chips hit a wall by about 2300mhz when using bclk to get it higher than 2133mhz.

I have an old pc with 450W psu. That should be enough to get it booted. So i will use the stock cooler for now. Do you think when it hit's 80C on aida64 i must return it for a new cpu as 80C is not acceptable. i know I will never hit that but at least i can try to return it and tell them to run this app and so on to get aida64 to run.

Also do you think running my ram on 2133 @ 1.5V is a bit unstable and that's causing my pc to reboot and so on? Maybe I worry for nothing and haven't tested it properly. But anyway will test on that other 450W psu tomorrow. it's not a high class cpu but should run it on stock clock at least.

Your RAM should be at 1600 while you're testing core.. Even if the RAM 1000% works fine, IMC can be unstable


As for quote above.. err.. Anyone can make themselves hit 100c by like 1.2v on air or closed loop liquid cooling without delid using certain types of stress. It's not a big deal because it doesn't happen in any real load. Instruction sets can't be used/abused like avx2 is in linpack for example, otherwise the move to avx2 would make Haswell@3ghz faster than ivy bridge@5ghz.

ok cool so i'm just going to do some testings. What program should i use to stress test my pc? is it ok if I use memtest86+ for memory and aida64 for cpu.? When I run aida64 should i just stress test the cpu or memory as well?

just one more question. how would this cpu be at stock vs my old i5-2500k @ 4.7ghz. seeing as new games will make use of more threads maybe the i7 will help out. So what do you suggest is the way forward? I've just read the fine print and I cant return it cause it's already been used.

I have 2 choices and either one is fine.

1. I work for a family software company and they told me that they will be happy to buy the system for one of the lead developers to develop on. will be in a basic 450w psu with the ram, mobo an cpu not going to stress it to the max all the time.

2. I can use it on stock speeds if i tested it is working fine tomorrow.

BTW what volts average is required for 4.2GHz?
