It happens usually every couple of minutes during Prime. I'll be at 1.360v most of the time, then it will drop to 0.984v for a second or two before going back to 1.360v.
I've tried lots of different settings in my time overclocking my 2500k (LLC levels, voltages and the like) but i always seem to have this. I don't like it because my watts drop to 20's and then go back up to 90's.
Is there anything that can be done?

No, 1.52V is the maxium VID on Intel whitesheets. VID is not Vcore.

You're probably hitting throttles. Check whether your BIOS is limiting you by thermal performance or by current (or power) draw. Change it to current/power limiting, rather than thermal limiting and watch your temperatures manually. Also increase the current capacity in your BIOS if there is a setting to do it.

 

I'm sorry that I don't know Asrock BIOS; I only know Asus BIOS for this CPU.

My gut feeling is throttling of some kind too. Hows your VRM temperature maybe its getting too hot?

I always stick a 80mm fan infront of my VRM but i water cool in a silent configuration so theres VERY little air flow there in my case. I only later take the fan off after knowing its stable and monitor temps for first week

sorry but what is VRM, and where can i find the temperature?

In Prime95 I check "custom" and then input 90% of my memory into the "Memory to use" window, and it doesn't stress my CPU.

That is quite weird, could post a screenshot of what you set in Prime.

Thanks.

P.S make sure you download the latest version of Prime 95 x64 and input around 6.5gb.

As other's have said, no it's not normal. I've seen your BIOS settings on page 736 and nothing looks out of the ordinary so I'm not sure, could possibly be thermal throttling. Have you tried reducing the Core current limit? try setting that 150. Also as mentioned above download the latest prime 95 from the OP if you haven't already done so.

Also if it is possible, could you post a video or something so we know exactly what's happening and how.

Thanks.

P.S hopefully I'll be updating the spreadsheet later on tonight.

I run all my games maxed out and get acceptable frame rates, These just happened to be what i played that day.
Serious Sam 3 loaded core 1 to 50%, cores 3,5,7 were all at no more then 30% load. Cores 2,4,6,8 were at 0% as expected,
Another Source Engine based game loaded core 1 to 80%, 3,5,7 to no more then 15% and 0% on 2,4,6,8.
I have just about every game you could be interested in seeing, i could run more
These were not old games either, my conclusion is that games are nowhere near cpu limited whatsoever, so other then bragging rights, theres no reason to even be consuming (as i tested it) +80 watts to provide +0.1v or for 4.9 ghz 1.475v and ~+120w compared to 4.5 ghz
No thats not normal. it should be pretty steady state. Unless your sitting there watching it hard enough to be noticing the transition between FFT's

I think its allot more then bragging rights.I benchmark more then i play games and benchmarks are way higher around 5.2 to 5.3 Ghz then they are at 5.0. I can break 10 on cinabench which isn't possible at 5 Ghz. plus in some tests i can get my 3dmark06 scores of a single 6970 close to a 7970 .here are some examples.I personally run 24/7 8 threads @ 1.46 volts 5ghz with my ram at 2136mhz i can achieve lower voltages with my ram running lower but it highly effects my ram benchmarks.Here are some examples just to show its more then just bragging rights.

Just showing 5.2 Stable also runs IBT 10 passes with no issues:
338

Cinabench @ 5.0
338

Cinebench @ 5.2

338

3d mark 06 @ 5.3 Ghz 4 threads

313

3dmark06 with 7970 and much higher speced build then mine

434

And my ram running 2136 mhz is whats causing me to need more voltage on 8 threads but huge increase in performance (I have tested all speeds to see if tighter timings with lower mhz really was faster.It was way slower with my setup)

440

I keep trying and following this thread to get voltages lower and have gotten them down a little so yes this thread is very helpful and i visit it every time i play in the bios.To me i can tell when the my CPU drops to 1.6 Ghz i can notice the small pause before the pc actually jumps back to the overclock so i run max overclock 24/7 but like i said under water with good cooling idle temps are higher then before but still only Low 30's Max load temps can hot 70c running prime or IBT.

also i get much better FPS in BF3 with all the Ultra settings maxed with the Gpu not exceeding 40c and the Cpu around 50 c so i can notice a huge difference going from 4.5 to 5 ghz also.

Just some Opinions but i also am on the mission of getting my Voltages Lower without sacrificing performance though.

Great Thread .Keep up the great work

I think I know what it is now. I was watching temps in HWiNFO64, when Memory Channel 0 Rank Max and Memory Channel 1 Rank Max reached 95 degrees the vcore dropped along with the multiplier. Under 95 degrees it never dropped once, but after it hit 95 it was doing it every minute or less. What is this and how can i fix it or stop it hitting 95 degrees?

505

Tried lowering Core Current Limit to 150 and disabling Thermal Throttling but it never made any difference

Heres a vid of what happens in CPU-Z

I didnt mean to strike a bad note with you, that was unintended. You asked a semi personal question and i gave a personal reason and some evidence to back it up. I in my second sentence said that i primarily use my machine for gaming. You primarily benchmark, which is different. a folder or video encoder would want as fast cpu as possible too.

I once upon a time like you primarily benchmarked on my machine but if you really boil it down, as a benchmarker its bragging rights unless your reviewing hardware or sampling hardware. Guess i maybe grew out of the bencharking scene, i dont know. My upgrade cycles have gone way down and im holding onto hardware for 3+ years because i upgrade when i cant play games with smooth framerates anymore.

My measurements were in actual games, not synthetic benchmarks, the engines written in benchmarks are actually written near-perfectly and will in fact make use of more cpu. While there may be a measurable gain in performance for +200 mhz or more in actual games, from my point of view as i touched upon in my previous post is it really worth +80-100W for 5-10 fps maybe even +20 fps In the case of the game already running at smooth frame rates? If your game is running under 60 fps you can 90% of the time point at it overburdening the graphics card, not the cpu. Not to long ago that wasnt the case however, which is why benchmarks were written in such a way to value cpu performance the way they do. first gen I5/I7 changed that however and i started observing even with my previous configuration of a 4.5 ghz 533 bus core 2 duo(only reason i upgraded was i noticed games started to actually work better enouth with 4 threads that it was worth the upgrade)

Perhaps you can blame the game publishers, they all seem like they feel that they need to write there own in-house engine and spend most of there investment capital on the engine and art resources, and due to rushing end up producing a inferior engine and spend minimal resources on story and actual content when if they licensed any of the big engines and worked on it from there they could have come out with a game in the same development time that either had incredible art resources and decent gameplay, or come out with it in half the time. Im somewhat waiting for EA to have some bean counter wake up and realize this and consolidate all there artists and engine writers for a year or two and build themselves a universal engine and maybe a petabyte or so worth of best in class art resources and derive all games from then on off of that instead of reinventing the wheel for every single game, only using artists for unique content. We are already really close to the point that all the games art look the same because its made to look real, not like what an artist decided to make somthing look like.
