i 920 Over Clock @ 3.36 ghz.memory timing OK?

[toohot]

Fatal Sorry, I forgot to tell you I set unicore to x16 is that ok or should I change it back to auto.

 

[Fatal]

16 is fine long as its stable if not switch it back to auto. I enabled Speed Step and C-states my core speed changed to 2.2 but my voltages didnt drop. I have never used power saving features on any of my computers lol! Maybe some one will chime in and fill is in on what needs to be enabled. My core temps dropped -3c though.

Edit: maybe its cause I didn't switch the Power options in windows to Power saver I had it on balanced. I have it on High performance all the time.

[toohot]

Ok i just enabled cpu Eist and the 3.8ghz get to max only under full load and the vcore drops from1.84 to 1.216v.It use to drop alot more @ idle maybe I disabled something?

Dropped vcore as you said and it is stable ,only did 15 prime95 test .I will do longer test later on

 

[Fatal]

I am new to overclocking i7's but I learn fast thats great you were able to drop the vcore. Power saving I dont have a clue lol.

 

[toohot]

Fatal I can'not find spread spectrum on my bios,can it be called something else.and is it better to leave load line normal or go for level 1.and should I set unicore to auto That should be my final questions for now because i am getting a little tired ,its not easy getting it as perfect as you can
but with evryones help we can get ther.

 

[Fatal]

Spread Spectrum I couldnt find in your owners manual so maybe you dont have the option to disable it. Here is the Load-Line instructions below it basically helps so you do have vdroop. Your Uncore is where it should be, it is suppose to be two times your memory so 1520+1520=3040 Auto would put it at 3040 any way. It took me some time to get mine stable lots of bluescreens lol so I must say I am far from perfect. Overclocking takes time thats all you will get the hang of it.

Load-Line Calibration
Enables or disables Load-Line Calibration. This item allows you to adjust Vdroop at different levels. Enabling Load-Line
Calibration may keep the CPU voltage more constant under light and heavy CPU load.
Standard Disables Load-Line Calibration and sets VDroop following Intel specifications. (De- fault)
Level 1 Enables Load-Line Calibration and slightly adjusts VDroop.
Level 2 Enables Load-Line Calibration and moderately adjusts VDroop.
Note: Enabling Load-Line Calibration may result in damage to your CPU or reduce the useful life of the CPU.

 

[n-ster]

oh god Fatal, you made him put voltages in without understanding them lol. Not a great way for him to learn :/ Remember, he is new to this, so keeping it simple and slow is best, with explanations if need be. Adjusting voltages should NOT BE in masses. best way is to play voltages STEP BY STEP.

imana step in again, see if everything is fine First of all, RAM timings are not done properly. tRCD is supposed to be 7, while RP and CL (CAS latency) are supposed to be at 6. Since you are running at 1520 now, try 1520 6-6-6-18 1.64V

Best results in Overclocking is when you put Load Line calibration at Level 2 (http://www.techpowerup.com/forums/attachment.php?attachmentid=41515&d=1301902532) put the 1st one at Level 2. 16X uncore is fine, I found that 13X and 16X give the most stability.

Here: http://www.techpowerup.com/forums/attachment.php?attachmentid=41516&d=1301902539 put the CPU core clock ratio to 21X, also, while we are at it, put the BCLK to 191

What I meant about putting stock voltages on auto is that for example here: http://www.techpowerup.com/forums/attachment.php?attachmentid=41515&d=1301902532 all the Auto voltages should be manually set to the stock voltages (on the left)

Disable any power saving features for now.

Dropped vcore as you said and it is stable ,only did 15 prime95 test .I will do longer test later on

did I read wrong? 1.84V?

I understand you are getting tired of playing with this, but IMO, it is better to do it now as you won't do it latter probably.

 

[toohot]

vcore drops from1.84 to 1.216v

n-star you did not read it wrong I was wrong,it was 1.184v @ 100% load the it drops to
1.216 @ idle.n-star is it ok to have it running @ 3.8ghz on idle all the time with cpu EIST off
.And I am worried about load line level 2,I have read mixed reviews about voltage spikes@ high vcore?

 

[n-ster]

ahh OK... High Vcore means stuff like 1.5V+. Even INTEL THEMSELVES say 1.375V is SAFE.

Load line level 2 is very safe with low vcores like ours.

I run 4GHz idle 100% of the time np. Most overclockers disable speedstep and the like (power saving features) in order to have better stability and the least problems possible

 

[toohot]

ok thanks n-star. CIE is enabled -leave as is ?
I will also do as you say -almost there.Your a legend and thanks for your patience.
Also running cpu @3.8 @ idle does it degrade the cpu quicker?

I set blk@191 clock ratio x20. If I set it @ x 21 it takes it to 3.99ghz cpu Eist is off.
load line calibration is now level 2.Timing is 6-6-6-18-1t trc 34 @1.64v.
will test for stability.

 

[n-ster]

ofc it will degrade the CPU quicker... instead of 100 years it will only last 99.75 years /sarcasm

again I will say, the CPU will outlast anything in you computer... even your case This is not true if you run your CPU at 1.5V Vcore, but you get the drift right? Do disable C1E and anything that claims to save power... If you want to enable them, do it after you test for stability with it disabled. I don't recommend enabling any power saving features however

btw, it's n-ster not star

 

[toohot]

Thanks n-star.set timing @ 6-6-6-18-34-@1.64v as you said , and bsod at start of prime95?
Is setting blk @191/clock ratio x 20 /3.8ghz ok?also temps have jumped 3-5 deg after I set LLC to level 2 @ primr95 100% load is this normal.
I am not going to give up!I have gone too far.sory for driving you up the wall,or is it the other way around?

 

[n-ster]

Yes, it is normal that temps go up as there is no more vdroop, we will lower the vcore later.

try to leave the thing you put 34 on auto and bump vtt a bit more. if that doesn't work, then put tRCD to 7 and tRAS from 18 to 20. You could also put something like 1.7V if you want. You could also try higher frequency but at 7-7-7-20.

191x20 is fine, but 191x21 is better obviously Try 191x21. If that works well, we can then lower vcore until temps are like before.

please, it's NSTER not NSTAR lol

 

[toohot]

Sorry for NSTAR.But you ar a star for sicking it out ,with a newby like me.I think I will give myself a star as well for hanging in.Thanks so much.I will try the above and fill u in on how it went.
7-7-7-20 IT @1.64v is stable after 2 hours prime95 test. I will try your timimng settings.

 

[n-ster]

Yes, you are a good newbie lol, doing your research, asking question instead of following blindly, being very nice to the people who help and as you said, sticking in there.

TBH, for me it is not a lot of work as I have no or little research to do as I already did all this research for myself, so now I know all this

Report back if 191x21 and 6-7-6-20 1T works well If you'd like to experiment with other timings and frequencies as I posted before, feel free to do so

 

[toohot]

Hi n-ster.Everything is stable @3.8ghz 191x20 testes on prime for 1 hr,will test longer later.
vcore @1.21v but readind 1.184.
Qpi ratio x36/unicore clock ratio x16/cpu pll @1.8v/Qpi pll -auto(shoul I set @1.100v)?
LLC @ level 2/CIE-off/cpu EIST -off
When i set qpi/vtt @2.26v it was stable.
I am abit worried that temps are so high @ idle & 100% load 76c 78c 74c 77c
The next step as you said is to lwr temps(lwr vcore if possible)?
see attached setting to see if all is ok.can I try and lower vcore voltage.thanks Toohot.

before I go to the next step of 191x21 I will see if we can get temps down.if not I will re-thermal paste cpu then try.

 

[Fatal]

Do you know your room temperature? Or what is the temperature outside I know it gets hot in Australia. With those volts you shouldn't be running that hot, Unless its hot in your room so you are smart to reapply the thermal paste.

 

[toohot]

I will have to get it done because th noctua cooliing is a pain to take off.The romm temp at the time was around 27C.so should I drop blk down to safe level.so I can get temps down untill thermal paste is applied.current room tep is 24c Idle realtemp @45,45,44,42c
Realtemp @ 100% load 74.75.72.73c.wht do you think?

 

[Fatal]

Those temperatures are awesome for the load the idle temps are high though. My CPU idles at 38c-40c but my room temp is 20c. Did you try the 21x191?

 

[n-ster]

As you said, you have 7C less Room temp, so his temps are perfectly normal, no need to lose so much time reapplying paste. Note that Under 80C is pretty cool for an i7 920. Some people run the i7 920 STOCK at 90C because of crappy cooler.

We will work on lower temps, but for now, try 191x21

 

[Dice]

hey have u guys tried intel burn test for stability testing? i found it much faster to do short runs of ibt initialy, then longer runs of prime (overnight) once i felt it was stable.

 

[toohot]

The Idle temp are always around 41c-43c it has has gone up by 1-2c.It is the start of autumn(fall),but we had a mild day.the weather will start cooling down soon .what I have been told by uncle web (creator of realtemp)who took me thru realtemp settings,he said the temps for 17 920 are normal @40-45c and not to worry.he said its the full load you should be looking at,His words.He also said the cpu starts to throttle @100c and @ around 110-120c protection sets in.he said voltages are the main killer,and that you would rarely use pc @ 100% load

As for 21x191 I think i will not benefit all that much @ 4ghz with high temps.I have done well going from 2.66ghz to 3.8ghz with all your help.Now I want to concentrate on getting full load temps down by lowering voltage,as n-ster said no more vdrop temps go up then you lower vcore
that will be my next step because I finally got it running Stable.

Oh-yeah n-ster did you have a chance to look at settings above -are they ok?

 

[n-ster]

Yea, IBT is a great tust, and shows your max temps very fast as well.

The thing is, toohot, that temps are lower per Mhz with the 21x multi. So either go 191x21 or 181x21 for 3.8Ghz. I suggest going 191x21. You are too scared of the temps and you shouldn't be. Try 191x21, you'll see a bump by maybe 1C that's it.

In the http://www.techpowerup.com/forums/attachment.php?attachmentid=41533&d=1301987381 try setting the vcore 2 steps under the voltage you set it at and put EVERY voltage that is on auto to the stock value. If you are lucky, that should lower temps enough. It PROBABLY will not work, but it would be good if it did.

What thermal paste do you use? unless you are in hobart or the other cooler areas, I'm guessing it is pretty hot outside.

Now that we have memory under control, Prime95 takes way more time than you need. Intel Burn test will do that job better now. http://www.softpedia.com/get/System/Benchmarks/IntelBurnTest.shtml

And yea, checked your settings during this post. As I said, try the everything stock instead of auto + 1 or 2 steps down. BTW, you got a GREAT chip. my i7 920 takes 1.2675V for 191x21, yours only take 1.2175V

EDIT: oh wait, I just noticed, at this point, you can try to put VTT at stock and Dram at 1.5V

 

[toohot]

NT-H1 is the thermal paste it came with the Noctua fan,I was told it is very good (as good as artic silver 5)I will try 181x21 first.Then beacuase I have the Oc bug I wil then go for the big one
191x21 and then I will do waht you said regardige vcor 2 steps under other voltages set to auto.
I has been a great learning curve,your help has been at highest order.I live in Melbourne very mild day.Fantastic day.

 

[n-ster]

atm it is cold enough for you to open your windows WIDE and let your room temp drop to 20-21C.

NT-H1 isn't bad, however, if you ever come across OCZ Freeze (EOL so no more definitively the best TIM IMO) or MX-2 or maybe even MX-3 or Shin-Etsu G751, do you one of those (preference in that order)

If you are doing 181x21, might as well do 1 step down voltage in Vcore already

A few minutes in Intel Burn Test should do 90% of the stress-test you need for 100% stability check. Look at temps, once you feel the temps are that there max or near it, wait 5, maybe 10 mins more, and that will be enough
