Hotrod an Aurora R7?

Ever the optimist, I'm squeezing my R7-8700K, maybe a little (?) over the top. I have a Samsung SM961 M.2 drive, which is fast. I traded the Dell/MSI Aero 1080ti for an EVGA ti SC2 with better cooling.

Just to make sure I land in trouble, I ordered an SL binned/delidded 5.2 chip, due Monday. And some Kryonaut. With the stock 8700K, I have to drop speed below 4.6 to do bulk 6-core videofile conversion at less than 85 deg cpu. The 5.2 may only be usable below 5 unless the Alienware cooler and case fan cooling are better than I think, so a rebuild may become urgent in my disturbed mind; tests ahead.

Letsee......850W psu is OK; new multi-fan cooler, oversize case, more case fans, maybe new mobo........

Results of the new cpu: it will not run stable at 5.2 on the Alienware/Pegatron board from XTU with my limited skills. However, it is doing nicely at 5.1 / 1.25 v. XTU and other short stress tests at avx=0 / no offset / static do not exceed 76 deg with the original 120mm liquid cooler and aggressive fan settings. Memory 32 GB 2933 at XMP1. EVGA SC2 1080ti o/c to 6000/2012. One annoyance: the resident bios will not let an XTU profile above an X50 or avx other than 3 survive reboot

I generally use every day at avx=2 / +100mv offset / adaptive running video stuff.

CinebenchR15 1665-1670
CPUmark 19,100; single-thread 3030

I may pick up to a Hero board and 4000 ram in the near future, and see if the board will fit into the R7 case. If it proves necessary to go to a 240mm cooler, I'll have to get a larger case and fans, but I kinda want to try a Stealth Alien first. Anybody remember the Sunbeam Tiger?

The aurora mono supports over clocking?

Not sure what mono means; single fan? It is busy, but OK for 5.1 with this chip.

A Maximus Hero and G.Skill 4266 ram will arrive tomorrow. Going to see how much trouble replacing the R7 board might be, for a few tests. Also have coming a Rosewill mid-tower case and 750w Gold supply, since Newegg discounted them heavily for 24 hours.

Stupid autocorrect.

Mobo = motherboard. I wasn't aware anything Dell put their name on ever had overclocking options in the Bios.

Yes, the bios has limited settings for use with K chips; see the service manual. No LLC and a fixed xmp1 of 2933. Alienware Command Center has pages for fans/monitors, win 10 modes, and O/C, with two preset O/C profiles of X46 non-xmp and X48 xmp1, or custom profiles to X50. Also has a stress test. Lacks some settings and limited ranges for others, probably to minimize potential damage. Big Brother Is Watching You.

XTU works in place of ACC's O/C page, but profiles with avx different from 3 and X settings above 50 don't survive reboot; the X51 setting I am using still looks right, but is not in effect, and requires resetting.

Will be doing a build with the Maximus X Hero, for the sake of O/C flexibility and better cooling.

My build was breadboarded, then mounted in a Rosewill GungnirX case in the last week. The Noctua U14S cooler with push-pull fans is working well, somewhere between a 120 and 240mm AIO. At 5.2 GHz and avx2, pulling loads at 95% or so on all cores and about 160w TDP, core temp reaches low 80's. I have run it this way for up to ten minutes or so, but haven't decided how much long-term test I want to do. The case came with three 240mm DC case fans, and I plan to replace them with four larger PWM's. My G.Skill 2x8 4266 DIMM's are running at 4000, but so far, the Hero won't boot above that. Once booted, they will operate at 4133. Need to know more about settings. I really like the Hero, being in control of the O/C and not having settings disappear on reboot. I'll downgrade the speed for everyday use, maybe use it on video.
Goodbye R7. Goodbye stock 8700K.

Sold and shipped the R7 today. I have been using a Roswill 750M ps in my build, but was not happy when I read user's reviews and failure rates of them and other popular brands. So yesterday I ordered a Seasonic Prime Ultra Titanium 850. If it's as good as their reputation, the build may change, but the Seasonic will continue.
