Intel Haswell Overclocking Clubhouse.

[MxPhenom 216]

AIDA Bench. Less on Read then 2133. But better on everything else. Latency dropped quite a bit.

 

[TheHunter]

Well these are kinda low for 2666mhz, not worth extra vccsa voltage imo.
you should be getting ~40gb/s by all.. Probably also older bios conflict and it sets some extra timings too lose.


Try 2400mhz main 9-11-11-28 -1T or 10-11-11-28-1T, this should give you 36-37gb/s by all,

Latency is also windows power plan depended, on balanced it will be at least 8ns higher compared to high performance.

Command rate @ 1T will lower L2 cache latency from your 4.7 to 3.2 or 2.8ns

I get this atm

Ill talk to Dave. I'd like to get 2666 set up right.

Don't think I am 100% stable quite yet. Thought I did update my BIOS, and then changed my settings back. within like 20 minutes of Prime95 I got errors on 2 workers/threads. Going to have to mess with it a bit more.

I do not think BIOS is the issue, as I have not ran Prime95 as long as I did since I have been messing with memory stuff so.

EDIT: This BIOS definitely doesn't like some settings I have or something good lord. BSOD all day. Went back to 0711 because I don't feel like messing with it much anymore. Just want to play games.

 

[TheHunter]

Try 2nd advanced timings all at auto, auto detection should be correct - at least for 2400mhz..

This is what anadtech used by adv timings, I had that for 2400mhz, but like I mentioned it new bios didnt like it and its best at auto.
http://www.anandtech.com/show/6389/gskill-tridentx-review-2x4gb-at-ddr32666-c111313-165v


Anyway, I just noticed this for that turbo wattage, default auto actually maxes it to the max xD, durations are the same..


180W, rest auto

all auto

Been playing around again and I saw VCCSA really helps by stability and overall raw performance.


4.7Ghz @ 1.284v, vccsa 0.050v, digital IO 0.005v

Lowest fps 224-228fps

4.7ghz @ 1.274v, vccsa 0.060v, digital io auto,

Also best score so far, I ran this bench at least 50times.. Got better min fps too at the same spot lowest fps 232-234fps,

* vccsa 0.050v with cpuv 1.274v can bsod 0x124


In both cases ram at 2400mhz, few times it looked like digital IO helped, but then It kinda choked by raw min fps.


And I noticed something else, saw the same thing by my old Q9450 & this benchmark, if there is a voltage issue cpu or ie now vccsa it will have sporadic fps drops by changing scenes or during a different scene, acts like its underpowered - sometimes even bsod.

Interesting. Seems like in a way, if you increase VCCSA you can lower the vcore a bit at the same time, while maintaining stability.

Yes, at first i thought its small steeps, but looks like it needs at least 0.040+ offset to make a difference.

Atm 1.270v is the lowest so far and it still passed all, but for that I had to raise vccsa from 0.055 to 0.065v..
But then again this is with ram OC, stock 2133mhz probably needs a little less. Didnt test that.



edit: that 1.284v is also ok at 1.280v, I used higher so that all 4 cores were synced to max 1.296v (internal core voltage), now at 1.273v core0 and core1 at 1.280v. 1.270v made all 4 cores at 1.280v.

New Asus Bios 1802 is out for most models


Z87-DELUXE BIOS 1802
1. Improve system stability.

2. Support New 4th-Generation Intel Core Processors
3. Before using the new Intel 4th Gen Core processors, we suggest that you first update the BIOS using USB BIOS flashback, or download the BIOS updater for new Intel 4th Gen Core Processors and then update the BIOS using it.



lol would be nice to know whats this improve system stability.

 

[Shou Miko]

TheHunter that i doubt Asus would tell otherwise they would have listed it as what they improved.

it could just be they just improved overall system stability...

 

[TheHunter]

Yeah I know


Its just funny, for example before 1707 I had to manually tweak DIGI+ to get the best stability at higher OC and manually set ram adv. 2nd timings for 2400mhz OC, now with 1707+ I have to leave almost all at auto to get the same stability and proper ram speeds.
Which is good no more fiddling with it

while in bios 1707 update it said only
-improve system stability

^^


Anyway I already updated to 1802, acts the same as 1707. :]

 

[Kursah]

Well I might have to see if it's available for the Pro yet. I've wondered what this "improve system stability" item has been for the last couple updates or better myself. In fact hasn't every update since June release stated that? Lol. My system has been super stable, have zero complaints. I'm super happy with my just a tick above stock voltage 4.3Ghz OC. I'll report back later. I have hours and hours of homework and exam studying to do....yay.

I talked to Dave about new Bios for Asus boards and he said the changed a lot of the memory and cache stuff. I guess more to the way he likes it.

 

[Womper]

I noticed the new BIOS as well, I'm staying on 1707 though. I still haven't bluescreened on it yet. Before 1707 I usually experienced 1 bsod per month.
I'm glad I went with an Asus, it's great getting frequent BIOS updates.

And those BIOS actually make a difference. Dont tend to cause more issues.

 

[TheHunter]

Yea Im also very happy that I chose Asus board.


I noticed this difference 1707 vs 1802

If I enable power saving c-states (default auto - off) it now stays in c3 state most of the time, with 1707 it use to idle in c7s more often (windows balanced power plan). No real difference though, temps stayed the same.
*monitoring with RealTemp 3.70TI


with 1707 I had to use max C3 anyway or it could get unstable, for example @high performance power plan it still used lower C6&C7 states voltage (0.020v sudden jump to 1.275v) and sometimes bsod by quick cpu usage changes..C3 was ok with 0.700 to 1.27v

Now with 1802 @high perf. power plan it disables any C-states, core voltage still hoovers though, but once in light/high usage it maxes and stays maxed.

With C-states at Auto its in sync with coreVID, so @high performance plan its always maxed - kinda like fixed voltage, only balanced power plan lowers it to 0.700v like C3, C6 & C7 drops to 0.00v.

I guess Auto seems optimal since @balanced its already using idle C3 type voltage.. But im not sure atm if it activates C states or not..

Question for you.... I recently got my i7 4770K and I would really like to try and get higher clocks. According to your post I see you have had some success with increasing your VCCSA voltage in order to lower your Vcore. You said 0.050v is the amount you used. Is that increase in Offset or manual measurements? Also did you notice a decrease or increase in temps?
I am on a custom loop so I am not too worried about higher temps (however lower the better still)
Last couple of questions: I have heard that Haswell is pretty safe with Voltages 1.35v and below. I have also heard Haswell can comfortably handle a lot of heat with out degradation. Are both of these things I've heard true? Also what are the average clocks people are seeing.

Thanks

increasing your vccsa, digital and analog I/O voltages should help get you higher clocks

Yes that VCCSA +0.050v is in offset, so total ~ 0.860v or so.. With this value i was able to lower cpuv for ~ 0.09v, from 1.283 to 1.274v or so.
It will heat a little more or around the same as by higher cpuv (kinda mixed tradeoff), but mostly it helped by my ram OC stability >> higher cpuv didnt help much.

I tested Digital IO, apparently it needs to be 50mv higher then analog, but i got more issues with it then at Auto value (bsod watch dog and kernel exepction), so now im keeping this at auto.

DIGI+ also all at auto, expect cpu current 110% for 4.6Ghz and 120% for 4.7Ghz. Ram current 120% (for ram OC).


As for the rest, if you have a good cooling then yeah 1.35v should be fine. I would try to stay below 1.40v though, just for "longelivity" reasons >>>> you might need to raise SVID - VCCIN a little , stock is ~ 1.80v, maybe try 1.85v if you go above 1.30v+


Also one more thing, try adaptive voltage for cpu voltage and cache voltage. By total turbo voltage set your stable voltage, idk if you need 1.23v for 4.4ghz then put that in. For cache the same total turbo voltage 1.17v.. Ps are you sure you need this high cache voltage?

Sometimes mobo overvolts more then it needs, my cache @ 4.2ghz is ok 1.137v, while mobo at auto sets to 1.22v, overkill.

just got my haswell rig going like wednesday

seen this topic and just wanted to share


what else can i do?

 

[TheHunter]

Nice! I tested mine once for 5Ghz, but I stopped ~ 1.33v (almost loaded windows)


You can OC that ram a bit, Haswell like fast ram, ideal 2133 or 2400mhz


btw what kind of volts do you need for something like 4.6ghz or 4.7ghz or 4.8ghz?

[Vego]

4,6 i run at 1,1v, 4,7 @ 1,13v, 4,8 @ 1,2v

also i always try to make my luck about chips -had only 2 retail processors, rest are ES's

about the ram, i bought platinium because its beautifull had dominator 2133 earlier but platinum are so expensive it hurts and ram does not have inpact on performance so...

Ring Max Multiplier: x42
Vcore Offset: + 0.065 = 1.216v (Full Load)
Ring Voltage "Maunal": 1.17v (1.20v Full Load)
VCCSA: +0.023 (Full Load 0.88v)
I/O Analog: Auto
I/O Digital: +0.005 (1.024v Full Load)
DRAM: 1.63v (1.645 Full Load)
C-states Enabled
CPU Spread Spectrum: Disabled

So I was able to bring my Vcore down by 0.014v by bumping my VCCSA up by +0.023 (0.88v). Looking around my VCCSA Still seems to be within safe tolerances...what do you guys think?

To answer your questions (TheHunter) about my Cache Voltage, I did do a little stress testing in order to determine my Cache voltage of 1.17v (Manual) 1.20v Full load. But I don't know if I stressed my CPU the correct way in order to determine it.
What type of testing do you suggest performing in order to determine your CPU Cache multiplier and voltage? And what method do you use?

To answer your last question too, I use a custom water cooling loop.... so my Cooling potential is pretty

Please keep the advice coming guys, it appears it is helping

Thanks

*Update* While I don't have a lot of time right now, I will tell you I quickly tried a different approach. I reset my BIOS to complete stock, set my Vcore to 1.2v (manual) at first then 1.25v (Manual) and I was not stable @ 4.6v or 4.5v. I have a feeling I just have an average CPU. I know I can push to 4.5v but it take 1.246 volts to do so.
Well I am not giving up just yet.... but I just wanted to through this added information in.

Mostly by cpu bound games when it stresses whole system..

Benchmarks like LostPlanet2 - test2 and Resident Evil5 - variable test; both dx9 mode, no aa
and in cfg (mydocuments/capcom) set jobthread from 4 to 8.


Bf4 will show it quickly too, mostly with WMEA 0x124 bsod.


Mine @ 4.2ghz 1.137v auto overvolts to ~ 1.162v total.

4,6 i run at 1,1v, 4,7 @ 1,13v, 4,8 @ 1,2v

also i always try to make my luck about chips -had only 2 retail processors, rest are ES's

about the ram, i bought platinium because its beautifull had dominator 2133 earlier but platinum are so expensive it hurts and ram does not have inpact on performance so...

Wow very nice, so from 4.8ghz @1.20v it then needs a huge bump to 1.38v for 5ghz?

Although I saw one 5Ghz @ 1.26v, i think he posted in this thread, that looked sick too.



btw, Ram has a little perf impact, i noticed it in cinebench , any 3dmark physics cpu score, cpu bound games when not gpu limited..
