Overclocking RVIE - 7900x

[mpoffo]

I have my system up and running and now I am playing with OC settings. I am looking for a mild but reliable overclock.

I have a questions regarding settings in the BIOs. My frame of reference is from OCing my 3930K on the RIVE.

So this is what I have done. I have changed the ratio to 44 on all cores to go for a 4.4 MHz OC to start. Tested it some and it appears stable. Memory is set to XMP mode and running solid at 3200. Did some realbench and HCI Memtest testing so far. I can probably go higher on my CPU OC.

On my old RIVE I had set the CPU VCORE Voltage to offset mode and set an offset of +.005. That setting would allow the CPU core speed to ramp up when needed and then lower when not needed.

I am trying to do the same thing on the RVIE. On the RVIE I set the CPU Core Voltage(not CPU VCORE voltage - RIVE, assume the same?) to offset mode and did the same offset of +.005. Question, does this do the same as x79? It appears to do something similar and ramps up when there is demand but I notice the core speed jumps around a lot more than the RIVE. Should I use a different offset value?

Also how would Intel Turbo Speed 3 and C-state effect these settings. Both are currently enabled. Should I disable?

Thanks for letting me ask these "dumb" questions.

It's preferable to use Adaptive mode for this type of OC. You simply set the ceiling Vcore in the Additional Turbo Voltage box. So, if you want 1.15V under full load, that's what you'd type into the box. You can check out the Broadwell-E OC guide on ASUS Edge up for a UEFI breakdown (most of it is the same for X299). There's info on how to use the Adaptive voltage in there, too.

Leave the Turbo and C-State settings at default.

If the OS supports it, SpeedShift changes voltages quite rapidly, so expect different transitions/activiation times compared to older platforms.

Thanks Raja. I will give that a shot tonight when I get home.

Hey Raja OC question too. With the VRM much more in the forefront on the x299 platform.. I've been trying to find some info about the Rampage 6 Extreme. Are there any particular settings with the LLC that you would recommend to start with? I haven't seen a lot on this aspect or if we should even worry about it to start.

I'm also seeing people starting at 1.2 Vcore and a minimum of 1.80 on VCCIN (max of 2.2??) Is this sounding right?

Thanks!

1) External DIGI+ controls are for VCCIN LLC. Typically, I tend to choose a middle value, then tune VID to get the voltage (VCCIN) I want when the CPU is under load.

2) You can copy that, or you can work up gradually, noting what your CPU needs. Just use a sound methodology for debugging instability. There are some tips in the Broadwell OC guide.

I reread that Broadwell guide and it is a good place to start, so starting at LLC 5 is safe enough and see what the CPU needs at various stages of testing. Seems sound advice. Thanks.

Another question. der8auer was talking about the various overclocking profiles on the Apex and the Rampage. Are these also a good "start' Spot for our chips. I know nothing will ever be perfect just picking a profile but to give us an idea on some of the things that Asus and the folks who provided them, what they were looking at might be useful.

I did not find any profile on either the Apex or Extreme boards. Just a standard gamers profile. Unlike the RVE10 which had specific CPU profiles.

EDIT: I suspect they will come with a bios update since all the CPU's were not available at the time of shipping.

Hmm. I had heard that Asus was going to incorporate a der8auer profile ...

There are memory profiles available under the DRAM Timing Configurator page, as far as profiles for core and uncore overclocking, every CPU is different, and the best methods such as specific core are something you would need to work on.
