So after completing my x99 build over the weekend, I've had my first bash at overclocking and would appreciate any comments and guidance to make sure I'm not royally screwing up particularly on the cache clocking

specs are as follows
5820k
msi krait
16gb hyper x predator @ 2400
r9 290
corsair rm650
the cpu and gpu are on a custom loop

currently I've got the core clock at 4.5ghz / 1.31V and the cache at 3.2ghz / 1.205V, VCCIN is set to 1.9V and all other settings are on auto

I've been running intel extreme tuning benches and 5 minute stress tests to check its stable (appreciate I probably need to stress for longer) - screen grab as follows


Am I right in saying 1.35 v core is the max voltage for 24/7 and if so should I be trying for 4.6 as for the cache how high should I be trying to go?

comments appreciated

Just getting into x99 overclocking myself and I have a question about the "turbo power limit" settings on these boards. I see you have yours whacked right up to 4095W for both long and short, which I believe is the max value the board can do. However, I also have seen brief comments in other threads which kind of say "change the TDP from the default of 140W to 250W". Are these settings one and the same? They don't specifically mention long/short or other such words, so I can't be sure if the 250W refers to some other setting in the bios. But it seems kind of sensible if it is the long/short limit, to set it to something along those lines, i.e. 250W as opposed to 4KW? My board is an Asus x99-Pro btw.
 
Truth be told I've only played around with the board for an hour and being a noob probably not best placed to answer

for what it's worth, aside from vccin , vcore and ring ive left all other settings at auto. I've read that the tdp design for the chip is 250W but when I was looking for LLC (which for the life of me I couldn't find) I don't recall seeing anything regarding turbo boost power limit short term or other wise

tbh not sure given tdp relates to thermal design wether this is equivalent to max power input but as I said I'm hardly an expert I'll have another play tonight but will definetly keep an eye out now you brought it to my attention lol
 
So continuing where left off last night with overclocking I'm noticing when running xtu that my temperatures Don't settle and rise in a linear fashion, for example the package temp will fluctuate between 53deg to 62deg a couple of times a second - I kinda assumed it would swing up and down by a couple of degrees but 9/10 degrees seems a lot

Being the 1st time I've used watercooling is this normal and purely due to it being water cooled or is there something else going on
 
Ok, so I’ve now got the point where I could really do with some assistance and would appreciate if anyone using the msi bios could help shed some light on a couple of things.

My first attempt at a decent stable overclock got me to 4.5 core @ 1.31v and 3.2 ring @ 1.205v with VCCIN @ 1.9v and all settings on auto, specifically the cpu/ring voltage mode. After stress testing and benching for a couple of hours I noticed that the voltage wasn’t reducing when the cpu down clocked, at least as far XTU, HWmonitor and cpuz were reporting.

I thought this was down to the auto voltage mode basically operating in override, If I set voltage control to override and use the same values above I can’t even get it to boot into windows, however If I remove the ring overclock and go back to stock, it does however become stable with just the core overclocked - so now I have no idea what the auto voltage mode is actually doing.

From doing some reading up on various guides and what not, apparently I need to be using adaptive voltage control which would require me to input a target voltage for the turbo boost voltage which may well be applicable on asus, gigabyte boards etc. but I cant find anything in the MSI bios with a similar title.

If I set voltage control to adaptive am I then supposed to enter my target voltage into the cpu core tab? I’m hesitant to try as I don’t want to find out the hard way that I stuck an additional 1.31 volts on top of the whatever the default cpu voltage figure is

Would really appreciate some advice

I can have a look at what I have mine all set at later when I'm back home. I'm currently running 4.3 core @ 1.25v but have had it pushed to 4.5 @ 1.30. Didn't have any problems with voltage reducing on idle downclock, so hopefully my settings can help (need to see what everything is at when I'm in the BIOS)
 
So finally had a little check. My core/ring is also set to adaptive just now.

CPU [email protected], ring [email protected], [email protected], sa voltage mode manual and sa [email protected].

You probably have these enabled, but just to check:

CPU ratio dynamic
Eist enabled
Turbo boost enabled

The only other thing I can think of is how your power plan is set up in Windows...? Having it at balanced or power saver should be enabled. If on power saver you should find that all clocks bottom out (along with voltage) until needed. Try cpuz stress to see what I mean and look at MSI command centre cores along with core volt in cpuz.

Hope this helps?

Thanks for that mate, i take it that once in adaptive you set your 1.27 vcore in the cpu core tab
i'd left the system agent voltage on auto so maybe it needed a touch more

Eist, turbo and what not are all enabled and Windows is set to balanced - I'd been playing about with the c states which has caused me some issues as it now won't boot when you take it out of sleep

I'll crack on having another play today but your settings have at giving me a sanity check on mine
 
Nice. I would suggest balanced over power saver too. Glad to have been helpful.

Indeed I set core and then the adaptive setting downclocks then boosts when the cores boost. They can slightly over boost from what is dialled in at the bios, so I would suggest not going over 1.3 and see if you can get it lower when you're stable @ 4.5. Less temps for the win!
