Try cpu strap @ 100mhz fixed and its source clock filtering to 60ohm.

There is also "spread spectrum" setting at bottom of that page.

Yes and this,

Does Gigaybte have all these options too?

 

[cadaveca]

Should, but since they only sent me a few 1150 boards, I have spent little time in their BIOS.

 

[Solaris17]

Unfortunately they dont have a spread spectrum that I have seen I set it at manual bclk 100mhz and tried 100.3 only to have the system boot and move between 95-96mhz ill keep playing with it and let you know. Im confused since your review didnt seem to indicate this problem. but I am probably just missing something.

Hey Sol!

What are you using to read the BCLK bus speed? If I use an older version of CPU-z 1.63 (one that came with my driver disc from Asus in June 2013 when all this crap was still brand new) I see a bounce between 100-97.9. If I use a newer-ish version...CPU-Z 1.65 it bounces between 100.0 and 105.0 and various ranges in between. If I use AIDA64 CPUID, it's solid 100.0. if I use Speccy it's locked at 100.0, and finally if I use ITU 4.1.0.12 it's 100.0 there as well.

Maybe it's just the software or version you're using? Maybe get a second reading opinion? Update? I'm sure you've covered all grounds there, but I wonder if the software reading that is too sensitive or misleading? I am curious to find out more.

Ok Im having a hard time again, actually ever since I updated to 1707 around a good month ago..

At first I was ok at 4.6ghz & 2400mhz ram, then after using this bios it somehow started acting like I used phase clock adjust @ 9..bsod or random freezes. Raised Vccsa a little (0.020+) and still.. Also digi+ part looks more picky, all at auto seems "best".. for example LLC5 & 130% is not stable anymore..


atm at 4.7ghz & 4.1ghz cache, vccsa 0.010v, in digi+ LLC6, cpu current 130%, VRM optimized. ram 2133mhz and I noticed some stuff with core volts

bios 1.280 - 1.282v
core0 1.280v <> 1.296v (fluctuates, in medium/high load)
core1 1.280v <> 1.296v
core2 1.296v
core3 1.296v
bsod in cpu bound games/benchmarks, unless I use Digi+ all auto and its not completely ok.

bios 1.283v
core0 1.296v
core1 1.280v <>1.296v (fluctuates; core1VID 1.281v)
core2 1.296v
core3 1.296v
^
I used this and today its unstable again, it bsod in RE5 fixed benchmark or LostPlanet2 fixed benchmark really quick. Both can use up to 110W cpu package power.

bios 1.284v
core0 1.296v
core1 1.296v (pinned; core1VID 1.286v)
core2 1.296v
core3 1.296v

Im at this now and all ok.


bios 1.285v
core0 1.296v
core1 1.296v
core2 1.296v
core3 1.296v <> 1.309v (core3VID 1.287v)

 

[TheHunter]

Sorry for double post, but I think this needs a separate reply


With 1707 Asus fixed auto ram timings detection @ 2200+, this is why i had such a hard time all of the sudden.. even at 4.6Ghz got a hard freeze by medium load.

Now all at auto expect main timings @ 10-12-12-31-1T & tRFC 214; vccsa 0.030v and in digi+ 120% for current ram.

before at auto, older bios

Also, TDP is probably the cause @ auto it apparently uses cpu TDP.. I've changed that to 200w, which helped by cpu current capability and stability.
^
LLC6 -LLC7 and all at auto passes too (digi+ section), but ram current needs to be 120% @ 2400mhz & Vccsa +0.030v.
Temps stayed around the same, peak 70-73C core0 @ Cinebench15 or fritz cheesh mark

If optional, increase the TDP limit of your processor to 200~250 Watts

http://www.guru3d.com/articles_pages/asus_sabertooth_z87_review,9.html

spotted it here, bellow
http://www.xbitlabs.com/articles/cpu/display/haswell-overclocking_2.html


Edit: now that im monitoring core voltage I noticed another thing, C6&C7 states will lower voltage even at high. perf plan.
at auto (all c-states off) its in sync with cpu coreVID., only windows balanced power plan lowers it to 0.700v.


Hm maybe its them c-states unpredictable.. C7 & C6 will use almost no voltage (0.02v) then sudden jump to 1.296v at full load, sometimes breaks.. Only C1 & C3 act like if @ balanced power plan (lowest 0.705v) and this seems ok.

C6& C7 is ok at lower OC though - up to ~ 1.20v, by 4.6Ghz @ 1.230v its already a bit weird..

So after reading the articles from TheHunter above I decided to see what my chip can do with stock voltage.

My chip reads 1.15v stock auto, stock speeds. So I started there, and went straight for 4.3Ghz. That article claims most Haswell K's hit 4.0-4.3 on stock voltage. I'm game.

Sure enough, though reading 1.16v under load, I am stable at 4.3Ghz. This allowed me to dial all my fans back and quiet my rig down. I also was able to enable the extra C-states, and I also enabled all power-saving goodies, this thing idles cool, runs quiet, temps @ load are cooler than at 4.5Ghz. Changing TDP helped here too it seems setting it to 250W does the trick, where I would get that random crash while testing, I've been solid. No dice at 4.4Ghz though. Dropping almost .1 V for 200MHz seems fair to me. Though only needing about +.1V to achieve a 1Ghz OC also seems fair. I'm gonna run at 4.3 for now, and see what else I can fine tune. I have my memory down to 10-11-10-26 @ 1.60v @ 2133. I want to try 2200 next, might up the BCLK and see if I can't eek a few more MHz out of this voltage.

My CPU input V is set at 1.76v, I am using adaptive on the CPU and Auto for the Cache (which runs 1.16v) with an 8x-40x setting.

I'm debating finding a way to remount my one SSD and 2 3.5" HDD's in my case to remove the removable HDD chassis for improved airflow from the intake fan to eek out a little more cooling airflow from min speed (with BIOS).

To control TDP in ASUS BIOS, we're talking about the Short/Long Duration Package Power Limits? You set both to 250W?

 

[Kursah]

Well until tonight I had Long on 250 and Short on Auto.

I just set Long to 200 and Short to 250. Will report back.

EDIT: Locked up sometime during the night. Gonna set Long to 210.

 

[TheHunter]

I think you can keep the 2nd short duration at auto, its x1.25 the first value.. Long 250w, short 250 x 1.25 = ~313w

I had it at 250w at first, then 180w and 168w,


4.7ghz & 2400mhz ram finally stable

cpu 47x @ 1.284v adaptive,
cache 42x @ 1.135v adaptive,

Digi+ all at auto except cpu & ram current 120%
*this Power limit at 180w
VCCSA 0.050v+ for 2400mhz ram OC (now ~0.860v).
SVID - auto (1.79-1.808v)

Edit: VCCSA definitely helps by higher ram OC, too low and it can bsod with watchdog or Wmea 0x124. With higher VCCSA 0.050+ it looks np, 0.040+ was a different story.

 

[Kursah]

I've been messing with my settings a little further this evening.

Set Short back to AUTO, turned LONG down to 150. I had dropped vcore below...forgot I had changed it. Back up to 1.152v core and cache (auto on cache tho) and dead stable in OCCT. I turned on voltage control setting (I forget what it's called atm) and I have wattage readouts on all my programs, at current settings, running OCCT AVX, my CPU hits 145W. OCCT PSU with Linpack hits about 110W. But so far stable. Not sure if the wattage readings are worth anything tho. I also put my memory to 2200 and 10-11-10-28 cr1, gained a little on memory tests. Kept stock 1.60v (set to 1.58 in bios).

 

[TheHunter]

Yea this new bios did indeed improve stability, but most stuff needs to be auto

 

[Kursah]

Ya I'm still fine tuning. I set my SVID to auto, and the voltage to 1.70v, reads 1.728 under load. So far so good. I had to put my memory back to 2133, 2200 just wasn't quite stable nor did it add much extra to necessitate beyond what tighter timings at 2133 could achieve.

1.157v seems to be the sweet spot for 4.3Ghz though...and I still have the LONG set to 150...may set back to Auto. See if it was a placebo effect on stability. So far though I can't notice any difference between 4.3 and 4.5 in anything I do. System is quieter and cooler. Win-win so far!

 

[TheHunter]

I noticed the same thing by 4.6ghz with core voltages (monitoring with hwinfo64),

if it fluctuates like between 1.280 - 1.285v, 1.284v was it (all cores at 1.296v full/high load). Then its always the upper value on all 4 cores.

4.6ghz @ VID 1.226v was the min/max to keep all cores at 1.232v, anything higher would make 1-2 cores at 1.248v.. 1.234v pinned all 4 cores to 1.248v so i end up with that. 1.226v wasnt fully stable and i didnt want anything in between lol

 

[MxPhenom 216]

Finally got around to clocking my 4770k, help from Dave, and stopped at 4.4GHZ 1.29 vCore. Been working on dropping voltages down a bit. I can get the cache voltage down to 1.125v, but below that I will crash in P95 after 8k Test 2 which hikes the temperatures into the 90s. Ordered a new pump yesterday as mine is on its way out and doesn't like to stay running 100%. Once the new pump comes Ill do more tweaking.

I saw you're testing 2666mhz ram, what main timings are you using?

did you raise VCCSA a bit for more stability, ie 0.050 or 0.060v+ offset.
And in digi+ Ram current % to 110-120%?


I tested it too today @ 2666mhz CL11-13-13-31-2T, rest auto but it would hard freeze in windows, had vccsa 0.050+ (4.7ghz, cache 4.2ghz) guess it needs more for 2666mhz and or lower cache freq.

Ill post screenshots of my settings when im back at my apartment a little later today, but i had to increase VCCSA by +0.100 and cache at 1.15v. Cache is at 39 multi still. so far this has been solid but still testing. before it would blue screen windows prior to increase vccsa and cache within a few minutes to an hour of sitting at windows idling.

I haven't yet bluescreened on the 1707 bios, although it happened so rarely with 1405 that I'll need more time to be sure. I'm using auto/defaults on pretty much everything- I just set XMP mode up for the DDR 2133, set max core/cache ratios to 47/45, and crank up the adaptive voltage to 1.28v on both of them. I still bump up the tFAW on my memory to 40, and change command rate to 1. I'm extremely happy with this Asus board.

 

[MxPhenom 216]

I haven't updated my Hero BIOS since about the 3rd or 4th release. Ill have screenshots of my BIOS settings for memory for @TheHunter in a few minutes.

 

[MxPhenom 216]

Actually here is one of my CPU and Memory VRM settings. To confirm that I do have 120% on my DIMM Current.



@TheHunter try these settings. Granted we have different boards/BIOS, but these could be a good starting point for 2666. NOTE: These timings are directly from @cadaveca











I wish I had a better chip, I wanted 4.6. I might be able to get 4.5 if temps with the new pump improve enough.

Needing 1.29v for this chip at 4.4 seems ridiculous. Ohhhhh Haswell........

 

[TheHunter]

I managed to get it working @ 4.6GHz and Vccsa 0.055+
But all at auto doesnt make high bandwidth (got 23gb/s read/write/copy), guess they only fixed it for 2400mhz (35.7 -37gb/s).

Ok thanks will try those another time.

Btw with latest bios you can use all at auto in DIGI+ and lower that cpu current to 120-130% max, I need 120% now @ 4.7Ghz and 1.284v, but only if i leave all VRM, LLC values at auto.


Ps can you post Aida64 memory benchmark

Yeah no more fiddling around in that digi+, now its in balance and doesnt use max values or use to low., ok except cpu and ram current %.

I used a little lower cache 42x 1.135v, vccsa 0.050+ and ram current 120% fixed the rest @ 2400mhz ram OC. 4.6Ghz needs only 0.030+, but same ram current 120%. Stock 2133mhz is fine at 100%.


I think you can leave tFaw at auto 32, mine defaults to 32 with stock 2133mhz, at 2400mhz its 37.

Ps can you post Aida64 memory benchmark, wanna see if you get true powah

I can get you that a bit later.

Your chip makes me jelly, I think I am going to get my chip to pop lol, and then do the Intel Warranty thing haha.

You should get reduced latency times in the AIDA memory bench with the timings I posted since they are a bit tighter then your main ones you are using that you mentioned earlier.

 

[TheHunter]

CL10 is no go at 2666mhz, min CL11-13-12-31. Those advanced can be possible

Its this below - Balistix elite, it can do 2690mhz @ CL11-13-13 1.70v

[MxPhenom 216]

try setting VCCSA to 0.100 offset?

Maybe increase VDIMM a bit.
