Your Haswell-E max stable OC

[springs113]

I plan on keeping mine after testing at 4.5ghz (5930K) for 24/7 use since that has a nice voltage point for me compared to 4.6 and 4.7 (Both of which I got stable). I may bump it to 4.6 if I feel the need for more power but right now I am happy and I want to prolong the life of my chip (MY voltage requirements after 4.5 get a little excessive).

Did you buy the Intel performance tuning plan?

Nope, for you see...

Hey folks, I think I have my 24/7 OC figured out for the most part. My chip doesn't seem to like 2700+ memory speed, even with the XMP profile, so it's at 2.66GHz, and the uncore needs a juicy 1.3v just to be stable at 3.5GHz. 4.375GHz on the core requires 1.3v as well and it's running hot enough as it is at 4.25/3.5 with my H100 basking in my R9 290's thermal output, so I think this is pretty decent. My room is also noticeably warm, but seemingly not as bad as when I had an HD 7970 + HD 7950 in my 4770K machine.

How cold?

 

[dumo]

About -160ishC

Wow that cold bug is really low I heard that a good 4930K bugs out at -140.

 

[dumo]

Yes, pretty low comparo to other ES USA 5960X chip. Problem is it won't scale more Mhz with uncore @ 4Ghz+ regardless of vcore. Too bad I only have 31L LN2 because this chip burn LN2 like raging forest fire

TT water 3.00 hold the load fine. CPU and GPU on h20

Are you going to take some 5930K adventures, or no?

Could you also share memtweakit for those DIMMs?

I'm finally getting some where stable on my overclock what do you guys think of these settings 4.45Ghz @ 1.28v 30min pass in realbench which is better than my fail pass on 4.5Ghz @ 1.3v .

Intresting BCLK you got there. I wonder are there any weird setting on X99 that have the same voltage lowering and stability boosting effects like on X79?

It does seem that way my old x79 was easier to overclock lol.

I get the same BCLK with my 5960X and 2800 MHz memory when I use the XMP profile, but the memory speed can be bumped to 3060 MHz with stock timings almost. The only thing I change on the timing are 2T to 1T.

I only test 1 5930K which will go to daily rig, so no ln2 for now

Heres 4X8 dom plat 2666C15 with settings @ 1.455V



Comparo to 4X4 Ripjaw4 3200 @ 1.595V

 

[LiveOrDie]

Umm my 5930K seems to like a wired bclk running this 4.45Ghz overclock i only need 1.26v and i passed 4 hours of realbench.

You, sir, are the man. Thanks a bunch, will try it out, see where I end up.

Still working on things here, seems my memory controller tops out at just under 2700MHz, so I have opted to use 125 BCLK and the 21.33x memory multiplier for 2666MHz and began playing with the timings. To get lower than 14-15-14-34 needed the main RAM voltage adjusted to about 1.27v or so (I set it to 1.3) and to get to 13-13-13-33/2T I had to raise the DRAM termination voltage from 0.600v to 0.628v. I also interestingly needed to add about 20mV vcore than previously needed for 4.25GHz (now 1.26v it seems) or the computer would fail to boot with the tighter timings. My uncore is still at 3.5GHz/1.3v. I have only adjusted the primary timings and may work on secondary/teritary timings when I'm home on weekends so I can avoid the system being frozen all day.

You can't use a 100 BCLK for any ram speed over 2666Mhz other than 3200Mhz thats why when you set your ram profile in the bios it sets your BCLK to 125, It is possible but take a heap of tuning and isn't worth the time, I run a 127.3 BCLK for 4.45Ghz @ 1.26v with ram on 2800Mhz @ 13.17.17.35 with 1.35v, Using 1.35v is fine as 3000Mhz + ram runs these voltages any ways but you also can go all the way up to 1.6v for the ram because the memory controller on X99 was also made for DDR3 memory, I'm not saying you should but thought i would add that in there in case you thought 1.35v was high, I still have to test to see if my system is stable on a lower voltage seeing my BSOD where related to the uncore being overclock from the higher BCLK make sure you set these and not leave them on auto.

R5E memory preset for 4x4GB Hynix Single sided 2666 MHz 1.5V runs fin on my 2800 MHz Corsair Vengeance LPX CL16

 

[dumo]

Hynix single sided kits have voltage sweet spot that different for each kit. Also specific to freq and CL/RTL settings

3200 CL15 @ 1.25V



3200 CL12 RTLs/IOs 49/49/6/8 @ 1.595V





Exact Vdimm, more or less then system will bd or bf at boot. For this cpu Vsa is optimal

Overclocking this platform definitely seems intricate, especially with RAM overclocking. For some reason, adding a little CPU vcore seems to help with my current RAM OC, otherwise my system just hangs at POST and returns to failsafe settings, or worse yet, thinks its BIOS is corrupt and flashes itself from the backup ROM, so I then have to flash the BIOS again to the latest version after it flashes from the backup BIOS and plug in all my settings again. I managed to get 21.33x130 to work, yet 22.00x125 would hang and reset at POST, even after loosening the primary timings a bit. I'm guessing there are some frequency/multi/voltage combinations that just don't work well, and 22x memory multi seems to be one of them IMO, for my setup at least. I did get this thing to POST at 3000MHz CL17 just one time, then the board throws a temper tantrum when you change just one setting and power cycles (even if the POST screen appears, the thing can just shut off and go to failsafe settings or say the BIOS is corrupt, especially when trying to OC the RAM) and even then the settings that posted once somehow never work again. I don't know if anyone else's boards pull this crap, but sometimes it takes me a half an hour or more to recover from a failed OC or diagnose what is giving me the black screen and failsafe POST shutdowns of death, even just adding 10mV vcore makes the difference and the system is completely stable...

Latest OC.
