The official rog forms had a guide that may help: https://rog.asus.com/forum/showthrea...r-Overclocking
Post 3 may be a good starting point. Raja was the go-to for info on that board.
VCCSA voltage/current settings may need tweaking. CPU PLL and PCH voltage too if the IMC is the weak link.
Thanks guys

Have any of you had any success in doing so?

Clear the CMOS, Re-seat the memory/CPU...

I have seen some where the bottom of the CPU (contact pads) were filthy and I had to clean those as well as the top of the CPU before it would make contact with the pins when buying a used CPU. You could always have a bad CPU also... hope not
yeahhh I really don't think a BIOS update would do anything. I'm 99.5% sure I've already got the bios updated to latest version. The mobo is pretty old by now and it seems like I've gone and checked for updates a few times and determined mine was already the latest. At the very least I know it's more recent than the 1680v2 itself. I might check again anyway but I really doubt it would make a difference.

750 watts PSU should be more than enough for this setup right? I wouldn't think the 8core would use that much more juice than my current 6core? Does the Xeon need any special PSU considerations? It should also be fine with the GTX970? I msgd the guy I bought the chip off of and he claims they test them all thoroughly. My system runs perfectly when I simply swap my 4930k right back in though.


I'll check the E5's contact pads just in case..

Bought a used one off 'the bay' and dropped it in, but no joy. Nothing comes on. Well, the CPU and case fans come on, but nothing shows up on my screen. The graphics card (GTX 970) fans spin up but go back off when I power on, so I guess it's maaaaybe possible the thing is booting but just the graphics card isn't coming on so I don't see anything? Really doubting that's the case, though and I'm not aware of a simple way to check...


Anyway was wondering if anyone had any ideas what may be going on here. I put the 4930k back in just to check and it still boots (I'm on it right now). It has nothing to do with any cables coming undone or anything like that, I made sure to unplug nothing (and again the 4930k works after just putting it back in). I also made sure to reset CMOS before trying the xeon chip. I'm wondering if the chip just isn't compatible with, or if some other component is just causing an issue somehow. Here's what I have:


Asrock x79 Extreme-4m
Patriot Viper 3 DDR3 PC3-12800 4x 8GB
PC Power & Cooling Silencer Mk2 750W PSU
ASUS GeForce GTX 970 STRIX

J7SC ...with all the various CPUs and P95 testing you do, you should get a 2000w chiller (for Christmas ?)

I've had it under a custom water loop then went to a simple Cooler Master 212 LED with Dual fans and that keeps the temperatures under control since I didn't need a vCore bump to hit 4.2GHz.

I do recommend it.
snap_4.2_Ghz_with a Be_Quiet_Dark Rock Pro 4 _which is a little smaller than the Noctura D15 but still does really well - 4.2 Ghz can be used with EIST enabled to lower the clocks when full tilt is not used. 4.2 Ghz is a sensible 24/7 super reliable clock with temps under 60 c under full P95 stress - Awesome

4.2 Ghz__1.110_v__asus_x79_deluxe_MID 50'S TEMPS PRIME 95_ <<<< I didn't log all the temps @ 4.2 Ghz because they were so low

It's just NOW starting to show signs of degrading. I had to back off from 4.6 to 4.5 daily @ 1.372v (after vdroop), to get stability. So thats like 4 or 5 years getting the balls beat off it and it dropped 100mhz.... lmao, amazing little monster.



Not a chance you'll get 4.5 with a 212. Think more like 4.3ish.

At 4.5 with my monster loop I see 60ish in prime95, but that's with liquid metal TIM, was near 70 with Kryonaut (mount was probably contributing tbh).

Temperatures don't matter much tbh, this chip is voltage limited not thermal limited. In the dead of winter with the water near freezing, it still takes 1.5v ish to get anywhere near 4.8.

LN2 isn't going to make the same difference as it does on some other chips, sure you'll get more, but it'll be limited by the whopping 25MB unified L3 on 1st generation 14nm.



Any X79 board (aside from the weird chinese crap produced recently) with a monoblock will handle a heavily OCd 1680v2. Without monoblock...I'd suggest keep package power around 160watts max.

The power phase thing, it's massively thrown around by people who understand the electronics often (thanks youtube) but don't actually understand what all that cool tech info translates to when pushing a chip to it's limits. Small story below on why you NEED to water cool the VRMs if you're going to load your octocore at 200 package watts for extended periods of time:

//story
I first bought a Rampage 4 Gene, going for a small form factor build when it came out. I threw in my 3960x ES and proceeded to take cracks at records at the time, sure enough, my 3960x ES was an absolute monster, scaling linearly up to 5.1 ghz!! Getting there though took a good chuck of vcore as one would expect, and drew a lot of power. Chip was water cooled and I was doing this in December, with window open, so room ambient was mid 40s f.

Hit it with a realtime priority intel burn test and.... smoke, sparks, and the magic smell. One of the MOSFETs had melted the solder under it and slid downwards on the board, it did autoprotect and immediately hard shutdown :O Like an idiot, I hit the power button to restart it after a minute of head scratching, sure enough, it still worked (lmao). Head straight to the ROG forums posted a picture and Shamino direct swapped my board out for one in his lab via DHL 2 day express, prepaid return provided. He wanted it to inspect and identify the failure mode, as it was one of the first sold in the US, and as far as I know the first pushed that hard, so I left all bios settings as they were and sent it to him to probe and prod.
//endstory

I have had 4 boards that would VRM throttle when pushed really hard and the VRMs were air cooled, every single one stopped doing it when I threw monoblocks on them instead of CPU only blocks. The old "monoblocks are for show" is 100% NOT true if you intend to actually flog your CPU, but, there are not many people out there who do, most people do some crazy OC get some scores and back way off to a middling OC for daily.

NOW: that was a lower power part than a 1680v2 when pushed to it's limits by a good bit. All these people buying ryzen boards, eschewing monoblocks and going with just CPU blocks, are blessed the Ryzen 1k/2k/3k are essentially tirds for OCing beyond what AMD has specced them to. The majority of the non-halo boards out there could not handle 200watt+ draws, air cooled, in a case for extended periods of time.
Hi, I reference the first part of your post and your own OC exploits - ! - I got a Corsair H150i - triple for a test bench - and did a test OC of 4.6 Ghz - @ 1.340_v_tested_in_P95_29.4 __temps reached_77_hottest_core_20k-points in passmark & 2550 single threaded [email protected]_1.110_v_rise_to_1.1 30_v_&_1.136_v_&[email protected]_4.3_Ghz__1.130_v_rise_to_1.150 _to_1.156_v__or in the region_of
