Running AC/DC at 0.01 and LLC level 5 as generally recommended from the various guides I've been reading

Thanks! Trying to get my chip stable at 5ghz. It went solid for a few days but crashed last night while gaming.

I think it might of been my memory settings.

I'm currently running p95 version 26.6 to find the lowest voltage I can use for 5ghz.

Then I'm going to game normally and see if she's stable before messing with xmp again.

You could try up to 1.45v if you set AC/DC load line to 0.1 but only recommended for short-term benching purposes.

VCCIO - I wouldn't go higher than a value that shows more than 1.25v in Windows
VCSSA - Wouldn't go higher than 1.275v - 1.3v (1.3v being absolute maximum).
(Values in BIOS will be smaller due to LLC settings you apply to CPU also apply to VCCIO & VCSSA).

Benchmarks aren't my thing. Just looking for a solid 5ghz gaming clock.

I'll try and keep it below 1.4, if I can't get it to work with anything under 1.4 I'll just have to drop it down to 4.9ghz.

Currently 34 minutes into this p95 run:
1.36V
5ghz
LLC level 5
AC/DC 0.01
Max voltage seen 1.376
Max temp 61*

Everything else auto, no XMP yet

That looks absolutely fine.
Tbink you'll manage 5GHz easy

I need water chiller AND delid to achieve 5ghz at safe 24/7 voltages.
And thats on an ASUS ROG Apex mobo. (ASUS's High end overclocking mobo class).

My 7700k is a very poor sample.









What prime95 load temps are you guys seeing with delid and custom loop, with AVX enabled and v.core of 1.35v and LLc auto)?

Also interested in peoples 'x264 16 thread' and also realbench temps at 1.35v in BIOS (llc auto).

I'm running the Asus Maximus IX Hero myself.

I don't think I can get it stable. I've run p95 twice at 1.36v and 1.38v both gave me the following error after about 55 minutes:
Quote:
"FATAL ERROR: Rounding was 0.5, expected less than 0.4"

I also ran Asus real bench twice, both times ran into stability issues with blender but it uses AVX.


1.36-1.38V adaptive
5ghz
LLC level 5
AC/DC 0.01
Everything else auto/default
Max voltage seen 1.396
Max temp 65*

Anyhow....happy to see you didn't killed it..
Let me know how it does if and when you re-delid and apply LM with the suggested method..

I ran realbench for 17 minutes and had blender instability. But it uses AVX.

1.36V adaptive
5ghz
LLC level 5
AC/DC 0.01
Max voltage seen 1.376
Max temp 61*

Going to increase to 1.38 and see what I get

some chips are sensitive to the core cache ratio , not sure if you set them manually or auto
or how high they are

but usually I would set core cache low to standard (me thinks its 44) and try to get max stable frequency with a voltage I'm comfortable with, and then try to raise the core cache

Core cache is set to auto. Along with xmp.

I don't think I can get 5Ghz staying under 1.4v

I've tried:
1.33-1.4V adaptive
5ghz
LLC level 5
AC/DC 0.01
Everything else auto/default
Max voltage seen 1.424
Max temp 67*

P95 gives me rounding errors and realbench gives blender instability errors.

Anything else I should try? Or just call it a day and step down to 4.9ghz

Alright well I haven't been able to make it through 20~ minutes of Asus real bench with any of the following settings:

1.33-1.4V adaptive
5ghz
LLC level 5
AC/DC 0.01
Everything else auto/default
Max voltage seen 1.424
Max temp 67*

That's with stock speed / voltage ram and stock cache.

Assuming it's safe to say I won't be running 5ghz on this chip?
