I9 9900k

It's good to see that this thread is getting back on track.

I stopped checking this thread out because of people repeating themselves and trying to make the same point all the time.

Now I can come in here and check what other people are getting out of there 9900k CPU's while tweaking and such.
 
Current settings:

4.9GHz sync all cores
1.32v adaptive (highest voltage 1.296v. usually 1.264-1.280 in game) so getting a lot of vdroop
LLC level 5
DRAM 1.35v 3200 MHz
SA 1.0v
IO 1.1v

using Asus z370g MATX motherboard.

Max stress test temps of 90c using kraken x62.

Have been holding off from trying for 5GHz as I don't think it's worth it for the extra temps. Already tried 1.35v. Passes cinebench but crashes in games.

Ty!

Where are you measuring your voltage in windows?

Can you set llc higher to reduce the vdroop a bit and see if that helps with the 5ghz clock, or is 5 the limit? Assuming you want to go that high ofc.

I mainly use HW Monitor.

That was my next thing to try setting LLC to level 6 or 7.

I think the vdroop is my main issue. I reckon this chip needs closer to 1.4v once accounted for that to be stable and it's already getting pretty toasty.

It's destroying everything I throw at it, so I think I'll leave it where it is and keep the temps in check.

It's like 10c higher than my 8700k delidded at 5GHz 1.280v already!

I agree. If the performance is where you want it then leave it at that.

At stock the 9900k has been great, I'm just trying to OC now for fun.

What setting in particular are you looking at in hwmonitor for the voltage? I have that open as well but I'm not sure which reading i should be monitoring. :confused:

Yeah, I only started overclocking because stock voltage was too high. I thought I could get better performance for lower voltage. At stock it was reporting 1.360v.

I am not in front of the PC atm but I think its close to the top in HW Monitor under CPU VCORE I think. Would have to check.

HW info is another good program I like. That seems to have way more readings. But HW Monitor is easier to adjust for viewing things you are interested in seeing.
 
With the Maximus XI motherboards, is there an option to set the CPU TDP? I have seen it mentioned with gigabyte boards I think :confused: that people were changing the TDP to 115 to allow better overclocks.
Is this something I should be doing on the Maximus Formula. Obviously I don't intend to hit that.

Edit : and what is the maximum 'safe' voltage for 24/7 use. I was looking at the sites that provide binned CPUs, including OCuk and I'm sure I read that they are using 1.35v

No, shouldn't need to increase, current limit should scale, too.

Maximum safe depends on cooling, but try not to exceed 1.4v

Thank you.

If i set 1.33 in bios and then hwinfo reports 1.27 - 1.323 vcore should i still be going by the setting in bios?

I saw that elmor said the boards were more accurate with the XI series but I don't know how that translates to bios settings vs hwinfo sensor readings.
 
I'm guessing that it is normal to see steady increases in mhz with small voltage changes, then after a certain point the voltage changes needed for 100mhz become much larger?
 
Initial testing with my 9900k sample, core at 51ghz, cache at stock 43, a quick 30 minute run with Realbench stress test to see how things go.
