Is this normal behaviour for the chip?

I was having some stuttering in a game, so fiddled with an app to prevent parking, which I later dispensed with. Just want to make sure this is normal behaviour now...

This is my processor sitting at desktop... Is is normal for half (or more) of the CPUs to be parked?

Nothing is parked, running at stock with nothing changed.

4790K installed, temps seem in line with 4770K but have gained extra speed due to default clock speed at similar temps.

Think that's me set until later next year for CPU / Mobo, when we finally see what AMD Have cooking up.

Any overclocking yet Boom?

Can't see the point personally, unless you're just interested in benchmarking. There's no point stress testing unless you're running a realistic bios setup that you'll be using 24/7.

The main advantage of these newer CPUs is the power saving; let's face it they're not much faster than the previous generation (or two). Running with manual full load vcore all the time for the vast majority of users/tasks makes no sense.

Agreed, it's ok to do that if you're just doing a bench run. If for a 24/7 over-clock I want power saving features on. Like to be as power efficient as possible, no point running max volts and clocks at desktop.

Might have a go later on not had time yet, for 24/7 I'll run this @ stock like I did with my 4770K, so the extra default clock speed is a nice jump for me.

If it does 4.4/4.6 Ghz for bench runs I'll be happy

4.6 should be pretty easy, 4.7/8 seems to be pretty much the norm on the 4790k.

Had anyone made the upgrade from an AMD FX-8 to one of these?

Currently considering moving to Z97/4790k from my 990FX/[email protected].

With the cooling I have, I should be able to push the 4790 to at least 4.5, hopefully 4.6. It would be partnered with a pair of 290Xs.

I was hoping to hold out for Zen, but it seems that won't be appearing until at least the end of 2006.

It's worth it, TBH. 4.4ghz stock will get you much better results than fx8320.
I got this CPU after already having owned i5 3350p, i5 2400, i5 4670k, i7 950, i7 3770k, i7 4770k, i7 4970k , lol.not mentioning dual cores or my former q6600

Problem is, i got 50c in idle, 80C when "light gaming" World of Warcraft Warlords of Draenor Ultra... and it goes higher. My rig is as small as my mountain boot(s), lol

I have a Fractal Kelvin S36, so should be able to keep the temperatures under control.

That's got me worried then

I'm wondering if something is set somewhere in by BIOS than means it's parking when ideally it shouldn't be!

ps: Thanks for taking the time!

cant see the point of finding stability with manual voltage then swapping back to adaptive for the full power saving features ? well how else do you know if the overclock is stable :confused:

??

that's what I meant at least, and yes using certain stress testing apps can overvolt (latest prime) if not using manual voltage and give false bsods

as example I get a bsod if i stress test my haswell at 4.5 ghz with adaptive voltage and all power states on, but on manual voltage all c states disabled it's fine

and swapped back to adaptive with power states on it's fine not had a single issue so it's a bsod caused by power states on and adaptive voltage on not that it isn't a stable overclock

if stability testing it's wise to find a clock and voltage you are happy with using manual voltage and with all power saving features off then swap to adaptive voltage (so the voltage drops when the multi drops) with power saving states on

I have vIn at 2v vcore 1.26 and llc @ extreme. I was reading in 8pack's x79 guide that u should use medium or high for 24/7 use. However that didn't have the single vIn that haswells do. I'm at 4.5Ghz with x36 uncore ddr1600 999927 1t. If I put the multi up by 1 it gets unstable. I found that BF3 was very good at stability testing, moreso than 8 hours of H265 encoding.

Edit: vIn was @ (auto)1.8v with 1.76v reported in bios h/w monitor. I set it to 1.82 with LLC medium and now its 1.8v in bios h/w monitor.

OK... I've used the parking tool to set it to "100%", so now no underclocking and no parking.

Hmmm... Not comfortable about pee'ing about with things like this mind, but I'd rather the process was running as straight forward as possible :eek:

Shame I can't just do a BIOS setting to say run at full speed with no parking etc.

WHAT'S THE BLUE LINE BTW? Mine is at max all the time?

What's interesting are other shots from around the web do show parking as a natural thing - http://b2b.cbsimg.net/blogs/c-svchost.jpg

@ NeilFawcet I believe the top graph relates to the processes under the cpu tab. They are colour coded blue is max frequency, green is CPU % usage. I just looked up what a memory hard fault was in the overview. Its former name was page fault which is less scary, it means when its detected that something is being searched for in the page file due to being unloaded from RAM.

I've got all c-state and EIST every cpu power saving tech on in the bios and I don't get parked cores. I believe c6/c7 relates to parked cores. I've got a 4690k.

So with my parking utility set to 100% (on my 4790K) its no surprise my blue line is max all the time as its running at max frequency all the time, and no parking is taking place.

On a spare machine running Windows 7 (with an I3-3240), I can see cores getting parked and the blue running running well below 100%.

This 4790K is running nicely, about 60c - 65c during gaming. Considering the clock speed I'm impressed with it.

Does 4.6Ghz OC with ease, don't want to push it any further in Mini-ITX.

If I wasn't an upgrade addict this would likely last me for years !

Please stay an addict

I can then buy your 4790 when you upgrade....

setter · 6 May 2015 at 10:05

What sort of volts for 4.6 Boom?

Tbh, ill probably keep the one in sig for a bit longer. Was considering skylake but might not bother.

snips86x · 6 May 2015 at 10:09

Nice temps Boom!

I'm beginning to wonder if the 4770k I had before had caused the H100i surface to be no longer flat due to the IHS being damaged.

Possible?

Ha, yeah I'm not going Skylake that's a definite but if the i7 5775C turns out to overclock well and lower temps my 4790K might end up on MM. Latest bios for my mobo supports Broadwell, these chips must be coming soon.. I am going to try and resist though. Honestly 4770K / 4790K are probably enough for next 5 years

But yeah my upgrade addiction

1.36v CPU, 1.2 VRing.

Yeah I'm skipping Skylake as well. I don't want to change mobo / memory this year. Might consider i7 5775C though, just need to see temps and how well it overclocks.

Cheers, temps are still high during stress test, but for real usage gaming / encoding there in the 60C's.

Your IHS got damaged? I've got a bunch of AIO coolers and still fine after couple years use. Not sure what would cause that tbh.

setter · 6 May 2015 at 13:02

1.3 for 4.7 here, but gaming temps can be anything from 60-75c. Mainly caused by gpu's heating up the case. Moving to a single 980ti/390x should help there.

R-TYPE · 6 May 2015 at 14:38

What's the best stress test for the i7 4790k? Had heard prime95 is not good for haswells? Had been using Aida64 stability test up til now.
