CPU Overclocking Freeze Problems

[Ollii]

Hey, In the process of overclocking at the moment and have hit the 4GHz mark

but it seems if I now go over it everything will freeze once the max temp Prime gets under way, here are my settings at the moment (I am running a water-cooled loop, A Thermalchill TA 360 with EK supreme HF CPU Block):

Speedstep, c1e and intel turbo are disabled

LLC = enabled (I have seen people mention 50% and 100%, how would that be done? or is it something different just with a similar name?)

ratio = 20

bclk = 200

pcie = 100

dram = 1603

uclk = 3208

Dram timings = 6-8-6-24

core speed = 4000

CPU voltage = 1.30

CPU pll = 1.80

QPI/Dram Core Voltage = 1.325

I think all other settings are just on auto.

The temperatures have not gone over 65 degrees yet. I just tried changing the multi to 21 but that resulted in a freeze. So has anyone got any advice on what I need to change etc ? Also a big question that I've been wondering is once you get to 200 BCLK do you then just change the multi ? because I've seen tom say like now aim for 200 x 23 and on his youtube page it says his on 200 x 23. So I am rather confused because I thought from things I've read etc that you just leave the multi at 20 and change the BCLK or is that just until the 4GHz mark?

All advice welcome as always and I would be exceptionally happy with an answer to that question above, Thanks very much

Oh and Tom if you do read this, I am aware you are tired of answering 1366 overclocking questions so don't feel obliged to answer this one as well

what mobo?

cpu pll 1.86v

qpi 1.48v

And yes 200 bclk is the sweet spot.

uclk to 4000

I'll try them and Asus Sabertooth x58

I'll try them and Asus Sabertooth x58

Then try these settings,and if it dont work out add some tiny nudges at cpu,qpi,cpu-pll,you are closing in m8

Ok thanks

I'll quickly try em and get back on here to report.

EDIT: lol as soon as this game has installed (taking forever...)

EDIT at 1:10: Hmmmm sorry no there's been a lot of hardware errors etc in prime. I'll up the settings again then and see

EDIT 2 at 1:23: Yay success, pretty sure it's good this time, though I'm now at 70 degrees on one of the cores

I'll push the CPU until around 78ish I think. Does this sound ok ? seeming as it will be a 24/7 sort of overclock.

EDIT 3 at 1:24: No I was wrong again, theres been an error on worker 1 in prime

(((((( time to up it again a little more. Getting there slowly but surely.

EDIT 4 at 1:35: Perhaps this time, all is going well so far, upped the voltage just a wince bit. Will see where it goes from here.

EDIT 5 at 1:40: Oh dear, it's a no again. Two cores failing at test 9

Time to up it again.

EDIT 6 at 1:59: I'd say it's going well but I have said it quite a few times and it ends up wrong so I'll just say that I am hoping for the best, will update as soon as it's completed/failed.

EDIT 7 at 2:13: Argh, it's got worse lol, 5 errors this time :-(. Time to really put the settings up!

EDIT 8 at 2:27: Here we go again, I've Pushed it more than I did the other times so I will be very disappointed if there are any errors. But we shall see, will update as soon as possible.

EDIT 9 at 2:45: WOOOOO guys! All cores passed the first prime test, everything looks very good so far, lets hope it keeps this way. Will update when next test is finished.

EDIT 10 at 2:59: Fantastic! Every core has passed two tests, I'm going to say that's reliable (Should I?) Right lets see if I can get this thing clocked any higher

EDIT 11 at 3:19: Tried really upping those volts for a 22 multi but I don't think It's going to happen, not unless I push it A LOT. I will elaborate in a new post.

nice 1 ollii thats cool to read mate

joys of overclocking

im just glad you never gave up mate

Thanks very much, and I'm glad I didn't either. Overclocking really is a fantastic way to spend an entire night, I have learnt so much in the last like 7 hours

One more update to do though.

 

[Ollii]

Right, here is more or less my conclusion to my CPU overclocking night, it will be in two parts.

Part 1:

I have finally managed to find a stable 4200 GHz clock on my CPU and here are the final specs of it:

Speedstep, C1E and Intel Turbo = Disabled

LLC = Enabled

Ratio = 21

BCLK = 200

PCIE = 100

DRAM = 1603 (Will try and push this now)

UCLK = 4009

DRAM TIMINGS = 6-8-6-24 (Will have to up if I increase the DRAM Freq)

Core Speed = 4200GHz

CPU Voltage = 1.35

CPU PLL Voltage = 1.90

QPI/DRAM Core Voltage = 1.50

IOH Voltage = Auto

IOH PCIE Voltage = Auto

ICH Voltage = Auto

ICH PCIE Voltage = Auto

DRAM Bus Voltage = Auto

All Skews/Spectrum's = Auto

Temperature Min/Max - Core 0 = 40/73

Temperature Min/Max - Core 1 = 38/73

Temperature Min/Max - Core 2 = 41/70

Temperature Min/Max - Core 3 = 38/70

(Temperatures after half an hour on the maximum temperature Prime test)

Stable = I think so

Part 2: This is the story of me trying to get a 22 multi.

I thought once I achieved a stable 21 multi why not go and try and get a stable one for a 22 multi seeming as I was enjoying myself so much. So I gave it two different attempts. In the first one I simply uped the voltage to 1.375, however this did not go well and I could not even boot into windows.

On my second attempt I decided to up the voltage a tad more; to 1.3875. I also uped the QPI to 1.525, This led to me being able to boot into windows and most things were probebly usable, however as soon as I put the hardest Prime on it... Oh dear the pc froze and subsequently crashed with a BSOD.

So overall I think I am going to keep with my 4200 clock as it has good temps and I really don't want to push the volts too much as this will be a constant overclock and I would also prefer not to need the fans on 100% all the time.

Needless to say I have thoroughly enjoyed this night and would recommend to anyone who hasn't done it so far (I imagine most of you have

) I think the most important point which marsey quite nicely pointed out is just to keep with it, it's well worth it.

So all comments are welcome, please feel free to comment upon my settings and I would love to receive some tips on how to make it even better

I will be posting my adventures of RAM overclocking soon, probably on this same post or maybe on another thread entitled "The Joys of Overclocking" with this post moved there. We shall see.

So lastly a massive thanks too everyone that has helped me get this far as I know without you guys I wouldn't of been able to do it

EDIT at 3:46 = AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH lol it's not stable. I think I need to up it just a tiny bit for this 21 multi. Will update soon.

EDIT at 3:52 = Ok right I've made one change. I've simply uped the CPU voltage from 1.35 to 1.375, I decided to go up this much as the temperatures aren't too high currently and I just want to make sure that this setting is 100% reliable so I will be running the test from now until I wake up. Goodnight all

EDIT at 4:04 = Erm this is not going well, every test I do on Prime it keeps erroring on at least one of the 8 workers. It passed them all on a lower voltage than this earlier. Could anyone perhaps suggest what is going on? The settings are the same as the 'Stable' ones above except that that failed when I did it again so I put the cpu voltage to 1.375 but apart from that the settings are Identical. I have them all written down so I am rather perplexed. I will leave this overnight and see if anyone of you can answer this, thanks.

cpu 1.35 give or take some tiny nudges here

cpu pll 1.86

qpi 1.54

you are really close now m8

And try stability test with linx(linpack) at 1024 rams and 20 runs.

If you thought prime was harsh,then try All on rams and 20 runs of linx.

The ultimate test is running f@h 24/7

Running at 4.2ghz now,you may also need to set volts on dram manually to 1.65.Try this one first.

Ok thanks very much

trying those settings at the moment and will try LinX once Prime has finished. Will let you know how it goes soon.

EDIT at 2:54: Nope after a long Prime test one has failed

I will try these:

CPU - 1.35

CPU PLL - 1.90

QPI - 1.55

RAM Voltage is already at 1.65

What do you think ? If these don't work is it time to up the CPU voltage?

EDIT 2 at 3:09: Now 5 of the workers have failed just in the first test at these settings. How is this possible? how can everything pass the first like 3 tests on lower settings yet when I put them up a lot of them fail on the first test? really confused, are the settings perhaps too high now ?

EDIT: Also how high do I have the problem size in LinX ?

Hmm,cpu a few tiny nudges up

qpi should work at 1.54-56

when you have it stable,then try to lower cpu-pll to 1.88 and if its a go,1.86

Set rams ,and problem size changes

there should be a dropbox also for setting rams

Ok thanks, I'll do some tweaking and see. Will update as soon as possible

EDIT 1 at 6:27: Passed the 1mb test on LinX

but failed the all one after 1 thing. Will test prime now.

EDIT 2 at 6:54: Failed the hardest Prime on one of the workers

trying small fft's now, will report shortly.

Question: What does my pc need to actually pass before I can say it's actually stable ?

 

[kilobravo]

I only used prime very shortly myself,but a 20 run linx with at least 1024 mb rams,and a finishing blue bar that reads "finished in xx min ,xx seconds without errors" ,and running F@H 24/7 without bsod ,random reboots or freeze problems.

Ok, thanks very much

EDIT: Hmmmm It failed a few earlier in LinX at 1024 by now it seems to be passing it ? i'll up it a little and then see.

EDIT 2: uped the settings a bit and it is passing it atm however is it normal for it to fail just after booting into windows ?

EDIT 3: I think I have finally found a stable overclock

Nice m8

,very nice

If you use ssd for windows,let it settle for 1-2 min.
