Hey everyone, so my 5820k is overclocked to 4.5Ghz via the multiplier but I noticed that in games, my frequency only goes to around 33 which is the stock clock that the chip likes to sit at. However, this is not because my overclock isn't being registered or whatever because as soon as I run 3Dmark or aida or any hardcore intensive software, it'll boost to it's full 45 multiplier. So I was wondering if this is because my games just aren't stressing it enough to need it to run at it's max settings or is this something I should fix?
Thanks.
By multiplier, do you mean the turbo boost multipliers, or the base clock?
Also which motherboard do you have? So we know what kind of bios we are up against.
I didn't touch the BCLK. It's at 100. I'm on an X99 deluxe. I set a multiplier (not turbo multiplier) of 45. But because I'm using EIST and all of intels power saving features it doesn't run at 45 until it's under load. My old CPU would boost to my OC in games though. This one doesn't. I thought maybe because my old chip was a 3570k and this isn't as stressed as my old chip cause of it's 6 cores and 12 threads.
From what I've observed with my CPU (same, with the x99-ud5 mobo) it only boosts to the higher clock speeds when necessary, so traditionally my overclocked CPU would sit at 4.5Ghz but when you look at the task manager or something you'd see the game only using ~50 - 60% of the maximum per core, I think that is why it doesn't clock higher.
That and I'v also read about some new power management wizardry in Haswell that allows it to go from full idle to full turbo in some ungodly short amount of time, this may be another reason Intel have opted to be a bit more stingy with the clocks.
Ah alright, yeah I'm gaming right now and my cpu usage is only like 12% it isn't even boosting to 33.
That sounds about on par then.
Yeah by base clock I mean the non turbo multiplier, just couldn't think of the name.
I also came from a 3570k, how do you find the performance difference?
I haven't really benched any games yet so I can't say but I scored much MUCH higher in 3Dmark. Especially in the physics portion where it stresses the CPU, my 3570k was getting around 15-20 fps and the 5820k was holding 50-55 solid. I don't really expect a huge gaming benefit but also render times are cut super short.
Yeah I haven't run any benches apart from cinebench, however when I'm running my concurrent VMs it seems a lot smoother, the 4 threads on my 3570k were overwhelmed at times when running three OS.
