I'm running it on a z390 Asrock Taichi w/4 sticks of DDR4 at 3216 Mhz (because I'm running my BCLK at 100.5 Mhz.).
You may need to adjust your power limits and max current limits.

Hi,

Im pretty new to this forum, to overclocking, and english isnt my first lengague so beer with me.🍻

I got a new system and after a little research i decided to overclock it and these are my results:

9700k 5ghz @1.28v(override) / LLC set to TURBO / vccio = vccsa = 1.11 (i can lower those) / AVX offset = 0 / Temps on blender benchmark stay on the high 70s peaking on the mid 80s.

On Hwinfo64 my voltage drop a little under load (idle @1.273v -> load @1.24v) on the VR Vout reading, but go up and down slightly on the Vcore reading (they go from 1.284v to 1.308v and keep jumping around with quick random spikes of 1.32v, these spikes are quite rare). These voltages where taken after an entire loop of Blender benchmark.

My question is if its safe to let LLC on turbo(there are 2 more aggressive LLC options above turbo) i assume it is if the VR Vout is accurate.

System:
Mobo- Gigabyte z390 UD
Cpu- i7 9700k
Cooler- Scythe Fuma 2
Psu- xfx Xtr2 650w

Ty in advance.

Edit: Photo of Hwinfo voltages and added some more info

Are there any gotchas associated w/BCLK overclocking of the 9700k in the 107 Mhz. range? I'm using BCLK primarily to overclock my RAM.

If you have a successful overclock, please post the following:
  • Motherboard
  • Clock speed
  • Type of cooler
  • AVX offset
  • CPU voltage setting (either manual or adaptive)
  • VCCIO and VCCSA voltages (which seem to effect CPU temps)
  • Observed CPU Voltage from HWInfo64 (VR Vout or VCore if no VR Vout) when stress testing
  • What stress test you did
  • Max core temperature during stress test
  • Uncore/cache speed

If you have a question about your system, please include as many of the above as you have in your question.
Gigabyte Z390 Aorus Elite
5 ghz
Heatkiller waterblock with peltier 2 stage chiller
AVX offset - 0
1.3 vdc - manual
VCCIO/VCCSA - untouched
1.3 volts measured via cpuz during p95 small fft's
163F/72C max temp after 4 hours p95
uncore - 47

Heat is higher than I'd like, but manageable. Huge upgrade from 3770k, jesus.

If it's not hot enough to hurt when you touch it, then it's very cool. - TwoCables

Fresh 9700k build on liquid, not a bad chip so far.

Got my 9700K to 5GHz with 1.285V adaptive and LLC at 5 (ASUS Strix Z390-F), ran OCCT for over 6 hours with no errors. Required abit of tweaking with vcore but its looking good so far, played some games on it the past few nights.

Only thing I got concerned about was when I left my VCCSA/VCCIO on auto with my XMP profile turned on (3600mhz, C18, 1.35V)....this jumped the voltages to 1.40V on VCCIO, 1.45V on VCCSA, only ran these for about 10mins of stress testing and my 9700k was hitting 90c with linpack (vcore at 1.30V). After some research, these voltages are apparently very dangerous so I've put them manually to stock and its been fine so far.

Only weird thing that happened with these voltages was my USB on boot wasn't working till I replugged everything....not sure if it was because I was manually shutting the PC down at times, hope I haven't messed anything up with those voltages that high.....damn auto voltage values.

What board are you running. I am on liquid in one of my torture racks so temps are not a problem. I am currently using An Asus Prime A Z390 with Gskill F4 3600 at 3800 and still trimming.

ASUS Strix Z390-F

Only using a Kraken x62 here with noctua fans, temps are much better when I lowered the vccsa/vccio to stock volts, still have my memory running at 3600mhz CL18 1.35v

Can you overclock a 9700k with a cheap motherboard?

can you overclock a 9700k or 9700f with a b360 motherboard or do you need a z390 board?
