It's either the 4790K or the new Asus Z87 Pro BIOS, but I'm no longer getting the AVX voltage boost. I'm now sitting +600 MHz from my 24/7 4770K 4.2 GHz OC at the same voltage. Prime95 stable as well without the voltage boost.
I figured it was enabled. The reason I asked was you did mention the temps were for my benefit to another poster. My 4690k you were comparing to doesn't have HT. Reason why I wondered a little if you disabled it or not.
Guess it's time to work on my 4.2ghz profile. 4ghz is getting boring
That bump in volatge is due to avx
Weired fact i found that when stressing my 4770k that i failed prime faster
with HT disabled i got my cpu stabe with prime 95 for 24hours at 4.4GHz then reenabled HT
and havent looked back no errors etc no weired problems in event viewer, no BSOD no crashes 100% stable
you can read about my fun time overclocking a 4770k here

I cant remember what version of prime i used if you want know i can let you know when i am at home
it may have been the older version without avx as i will never come across that situation in the real world and if you throtle due to temp you cant stress test (im on air so i can throtle with avx2 load)

Lol, '4Ghz is getting boring'
I am going to see how high i can get now that i have fixed those temps, im hoping for at least 4.5Ghz
I updated the BIOS too but still getting the slight voltage bump even though i have it set to manual... I have so far found that 4.0Ghz is stable at 1.078v.
I hate stress testing. I know it's important but seems to be a waste of electricity at times.
My z97mx gaming 5 motherboard voltage settings are funky. Maybe it's a z97 thing as it's my 1st one I've used.
When I started overclocking my chip I set vcore to normal and used an offset which seemed to work. When I starting working on my profiles instead of the normal with offset I chose to just type in a vcore. I figured it was going to do a fixed vcore. When I was working on my 4.2ghz profile I just set a higher vcore and touched nothing but the multiplier. I noticed that it would still drop the vcore when the cpu was idle. Guess it went to adaptive vcore instead of fixed. Looks like what I type is the target under load now. My motherboard also ups it a little bit it looks like. Similar bump to what yours does.
I'm playing around with a 4.4ghz profile now.
What speed or profile do you run your H100i's fans on? I don't really like the sound of my fans at higher speeds so I got them locked at 1500rpm.
As for my fan profile, i normaly run balanced, i find it gives a good well... balance, between noise and temps. Ive tried custom, but it seems a bit off to me somehow....
The little xtra vcore you get from what you set is the motherboards LLC. Pretty much normal unless you disable it.
I'm overclocked to 4.4ghz currently. Not stress testing at the moment just doing some real world things. Kind of want to see what the temps are just doing the everyday things that I do. Also in the past it seems like doing the normal low cpu intensive things would trigger bsods. Going to start Prime95 soon. Was playing around with Aida64's stress test but it f's with my web surfing at times as it makes Internet explorer unresponsive at times.
I tried quiet mode which lives up to it's name. Don't think it would hang at higher clocks for stress testing at least.
I tried balanced mode which wants to run around 1800rpm and up under stress testing. My fan(s) make a cycling humming noise that I don't like.
Running fixed at my tolerable sound level works best so far for stress testing at least.
Once I pick my overclock and get to the real world temps then I'll evaluate what works best then. Would be nice if quiet mode would hang.
I haven't even dropped my TriX 290 in my new build yet. Was debating on keeping/trading/selling it. Still haven't decided on what I'm going to do.
did u do a flat test on the cpu block b4 u applied it to a delided CPU?
most waterblocks are bowed to apply center pressure.
A bowed block on a fragile die is asking for trouble.
Put a razor on the surface of your waterblock and see if u have gaps from end to end.
If you do, you may need to LAP the block for a flat surface.
Ah, so thats what the LLC does - didnt know that.
Personaly i would rather stress test and know that i have a reasonably stable OC than be playing game or something, then get a sudden BSOD... i dont actualy test for very long - i figure that if i am going to get an error or BSOD, then i will get it within the first hour of Prime... I have no experience with Aida64 so can't comment.
Yeah, same here - dont think the silent profile would hold up under stress testing.
Not really sure would the rpm is on balanced, but i know what you mean about the hum, it personaly doesnt bother me as i use headphones, but id imgine it becoming irritating after a while - or maybe you'd get used to it(?)
Why havnt you put in the TriX 290 yet...? Thats a good card, personaly i would keep it - although i dont know what you have in your pc now.
Aida64 stress test is more or less what is suggested for testing Haswell. Many state Prime95 with AVX hits Haswell too hard.
I'll do a little over a couple of hours with Prime before I kill it. I'll then use Aida's for about the same time. Figure if it doesn't crash by then it's good for the everyday real world use testing. Not like I work for NASA or do any critical work on my rig anyways....More of a toy for me.
Looking at the taskbar by the clock you'll see the Corsair link icon. If you right click on it a menu will pop up with options. You can switch profiles/modes or see what your current fan speeds, pump speed, or see the temps that the app is monitoring.
Currently sporting the good old Intel integrated graphics
I'm probably going to drop the TriX in today. Dreading the downloading steam games. Hmm I think I did back them up before I wiped my SSD. Guess I'll have to take a look and see.
So you delidded simply by removing the cooler! Pretty good deal for you in the end because that silicone glue was the culprit. Not all scraped of by the previous owner, but it may have worked OK temporarily for him.
The fact that the heatspreader slid on the silicon die means that the heatspreder is actually sitting directly on the 4770K's die and is not supported by the glue (gone now) or the chip pcb - it is stabalized by the CPU socket clamp. As Idontcare states, the silicon chip die can handle that pressure and you will have as good a contact between die and heatspreader as you can get. This is the configuration I have except I am using an air cooler. To get a few degrees cooler you can use liquid metal from Coollaboratories between the die and the heatspreader and between the heatspreader and the coolers heatsink. But it seems you don't need to go that far. I used the Liquid ultra between the chip die and the heatspreader since I had already delidded it anyway, but used the Noctua TIM beween the heatspreader and the Noctua heatsink. I did not do any lapping, but I saw 20C decrease in temps.
I have found that being off by a hundredth or two is within expected parameters. You are way under the point where you start sweating the voltage, imo. Go above 1.3 on an i7 and then it starts to matter more.
Btw... you mentioned something about it before - i am trying for a 4.3Ghz OC atm, and i have the voltage manualy set to 1.13v, but according to HWMonitor the actualy VCore is at 1.152, so my question is - why does it keep jacking up the voltage even when i set it manualy, and how do i stop it doing that?
OP - you might want to change the name of this thread so people know you figured it out.
What happens if you just input a little lower voltage? I know most boards don't work exactly as inputed all the time. Upping the vcore 0.005v may get you no more, but upping the vcore 0.007v might get you 0.010v for example.
You are doing really well. My 4770K needs way more voltage than that at 4.4. I usually end up with my ring bus at 4.0, but others will likely know more than me about it. Keeping it lower can help stability and has a small impact on performance. Try messing with one variable at a time, and raise other things after you get the CPU where you want it.
Im currently up to 4.4Ghz - but hard to get it stable, I'm already up to 1.151v and I'm still getting errors, anyone know if im supposed to increase the cache speed along with the processor speed?
Ive seen something about a ring bus in the bios, but havnt changed it because i didnt know what it was for... is that important for overclocking?
Btw... do you know how to alter the Title? Ive looked but cant see anything - wanted to put [SOLVED] at the end.
