Enjoy:

gsat stable, HCI too, but it takes forever to do laps. redface.gif
yeah, sure they sell well. A least one posted picture must have your ocn mane and date on it.

Have you tried lowering your ..... ah, what is it called... DRAM CLK Period? I'm not 100% what its called, its towards the bottom of DRAM advanced config. I'm able to run it down to 8, anything lower no-post's. It changes all auto-configured dram timings to that of the appropriate DRAM MHz divider. So you could run 3400MHz RAM but use the timings that would get autoconfigured to that of a 2400MHz kit, or some other divider! Just takes some tnnkering. Essentially 'free' performance gains.

Here's before.





And after I set clk period to 8. Gains can be better with higher uncore speeds. Only running 4.2 for the moment since I'm still fighting with uncore speeds.

All Broadwell-E owners,

 

Would you consider signing up with OCN Team Boinc for the upcoming 2017 Pentathlon (May 5th through May 19th)

 

This event is truly a GLOBAL battle with you team OCN going up against many teams from across the world and while we put in a good showing at last year’s event by finishing 6th, we could do with a lot more CPU/GPU compute power, especially CPU POWER.  All you need to do is sign up and crunch on any available hardware that you can spare.

 

The cool thing about this event is that it spread over 5 disciplines over varying lengths of time (different projects) so there is a lot of strategy/tactics involved.

We look forward to having you and your hardware on our team.  Again, this event lasts for two weeks and takes place May 5th through the 19th.

 

  • Download the software here and get a few GPU/CPU units crunched before this event begins.

          https://boinc.berkeley.edu/download.php

          Note: For every project you fold on, you will be offered if you want to join a team - type in overclock.net (enter) then JOIN team.

 

  • Remember to sign up for the Boinc team by going here:  You can also post any questions that your may have - this group is very helpful :thumbsups

          8th BOINC Pentathlon thread

          To find your Cross Project ID# - sign into your account and it will be located under Computing and Credit

 

         

 

This really is an exciting and fun event and i look forward to it every year and I am hoping that you will join us and participate in this event :grouphug:

 

BTW - There is an awesome BOINC Pentathlon badge for those who participate :thumbsups

OCN - FTW:sonic:

thanks. clk period is at 13 on this BWE rig.
If you look at the timings I posted several (rtp, faw, tCWL) are already as low as they can go. You should be able to run tCWL at 9... this will drive rtl and iol lower.

be sure to verify stability with HCi or gsat too. http://www.overclock.net/t/1569364/official-ddr4-z170-z270-and-x99-24-7-memory-stability-thread/0_20
I'll look for ya on the 64GB HWE list

post #6325 of 6480
glad to join this thread. got a 6900k recently and i have been OC-ing. i currently have it stable at 4.4ghz @ 1.325 VCore. I am running on a Asus Rampage V 10th edition.

other settings are:
Cache 34
Cache voltage 1.15
LLC 6
VCCIO 1.05

RAM is corsair dominator 32GB (16x2) @ 3200mhz @ 1.35V (stock)

also my workloads are not particuarly intensive and i am using a predator 360 AIO w GPU loop.

I am trying to get to 4.5 just for the kicks, so far i have tried up to 1.39 which could successfully boot but i was unsure of testing it since the voltage is a bit high. i've read over various forums and so far i understand the consensus for 24/7 use it is good to keep it under 1.35V, is this right?

does anyone have any tips on what other settings i could change to push for that magic 4.5?
post #6326 of 6480
Tweaking the memory cache today. Current results.
post #6327 of 6480
More tweaking. Tweaking cache settings. Not sure if I'll be able to push to much more beyond this point since my CPU package temps were hitting 80 C during benchmarking.

Slightly off topic.
I bought 2600K in Jan/Feb 2011. This has been running at 4.7GHz since then.
Just for fun, I ran OCCT overnight on 2600K system yesterday. This Sandy Bridge is still kicking hard at 4.7GHz with 16GB G.Skill DDR3 2133MHz 9-11-10-28 1T thumb.gif

for OCing a 6900K @ 4.0 or 4.2, would you watercool the mofsets as well, or is ensuring a good airflow sufficient ?

Hi, I tried with your settings and got errors in Hci (with tWR and tRFC set only)
Tried with step by step re-setting all sec timings to auto first and then increasing the primary timings back to 14-14-14-34-2T and I'm still getting Gsat errors.
All running at 3400, 1.45v and also the both vttddr increased to 0.72500 thinking.gif
Not good overclocking ram kit?
Shall I try 3466 (with different timings)?

Depending of the mainboard but a good airflow will be enough for 4.2Ghz IMO thumb.gif
