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

[toohot]

update.vore@1.237v( cpuz states 100% @1.168v & idle @ 1.2v) vtt@1.28v mem@1.6v.

Other settings are:C1E disabled/EIST disabled/unicor clock disabled set @ x16(2x mem)
qpI pll @auto/qpi link set @ auto/cpu pll@1.8v do I need to adjust IOH it's set @auto(1.100)

I set LLC to standard becaue I am still a little worried about level 1,I am confused about vdrop stuff.what I have read is to use at risk but it is usefull at lower voltage?.Also is it possible to enable C1E and EIST( power saving) I like to save energy@ idle and prolong life of cpu if possble.current temps average 68 70 67 68c.room temp 22c case temp 20.5c.

Should I do IBT test @ extreme and for how long.And do i need to prime95 test.see attached

[n-ster]

noooooo, going in the wrong direction here, we were doing progress! LLC is only dangerous once you get into EXTREME overclocking. We are talking over 1.5V, wight now we are WAY BELOW even INTELs max spec.

As I said many times, unless you want to keep your computer for 20+ years, the CPU life won't be reduced enough for you to experience it. if you want to enable C1e and EIST, it is not now. We do this only after you are 100% sure you are at your final OC. Those temps are freaking low, so temps are no problem for now.

If CPU-Z states 1.2V as the max voltage you need, then try LLC level 2... again, LEVEL 2, (TWO)... with Vcore at one step over wtv 1.22 is (1.2225V or 1.2275V) and try that. If that doesn't work there is something weird going on. The whole point of LLC is to lower your actual Vcore and temps later on, but even if it doesn't, it does stabilize your voltage.

[toohot]

sorry for changing LLC.I will be happy if cpu life for 3-4 years.I will do as I am told.Master N-ster.
I am doing a virus chack beacause the word around here is that a virus is stating it is virus protection and people .it is infecting alot of computers and computer servicing people are flat out trying to fix the problems.Keep an eye on it.its getting in the back door under different virus codes.computers have slowed down and do not work.
Also should I test IBT @ etreme.

[n-ster]

Yes test IBT at the highest setting. The point of IBT is to see MAX stability and temps

People (ie: friends, family, friens of friends, my sister's friend's friend's brother's friend's oncle ) are coming to me with that virus... gets anoying being the go to guy lol.

[toohot]

Ok finally everything is stable running @ max IBT,temps are higher using IBT @ max. see attached.LLc @lev 2.
vcore @1.225v vtt @1.28v maem @1.6v.what to you think re temps. and should i use prime95

I will order IC diamond 7 and re apply before oc @ 4ghz.so far so good.

[n-ster]

idk much about IC diamond 5 so I can't comment on it. If you can get MX-2, get it.

weird, my LLC lvl2 gives me 1.28V when vcore is set to 1.275V... Why does yours gives such a difference?

Temps are good enough, no worries for now. As a rule, don't worry about temps for now until they get past 88C. Now try setting 1.2375V and 191x21, and make sure LLC is at the highest setting

as you said mx-2. re voltage difference.could it be cpud error reading?

outide temp is 27c romm temp is 24-25 getting warm.I will go for 191x21 ,but not until I re-apply thermal paste i have to order it not available in my area.only
paste available is artic silver 5.I will now test using prime95.fingers crossed.
Is it time to go for power saving .

[n-ster]

no not yet.... power saving doesn't save THAT mmuch power.... just because it is running at max speed, doesn't mean it is = to it being at full load, remember that. HUGE difference between 4GHz at 0% load and at 100%. Power saving will save a few Watts, but nothing groundbreaking

[toohot]

Ok.Thank you.Whats a few watts anyway.I need aircon running in this room.computer is warming it up.The room never gets to cool down anyway its on 16 hrs a day.wife,me and the kids.The thing never stops.Any way look at Aida64 specs attached

[n-ster]

Last time when you tested with 3.8Ghz and LLC at standard, it was 1.2V and under 70C? with LLC it is 1.2V but with higher temps? makes no sense lol.

Try setting Vcore at 1.20XX volts

[toohot]

I noticed in some tutorial that the original person mentioned there is some intel logic bug that requires you to set unicore 2x+1(x17 instead of x16) instead of just 2x. After doing that, he was able to do much better at his overclocking ventures. this maybe true because when I set unicore on auto it gives me around the x17 figure.fiqure that out?
I will try once more @ 1.2v vcore

[toohot]

latest update set vcore @1.2v 15min ITB test @ max = stable.Temps have improved see attached. idle temps high but that does not realy matter at the momment.room temp is 23c.warm night.Fantastic weather/walked the dog,lovely day.
Under 70C? with LLC it is 1.2V but with higher temps? makes no sense lol - don't forget the test i did earlier at very high not max.

Do not worry about temps for now untill I reapply thermal tooth paste .Yes thats right,people have been known to do that.

[n-ster]

Great stuff.... So for now you do not want to try 4Ghz I presume? If so, for now, you could try to put higher speed on your memory. try to bump your mem speed, and set mem at 1.64V with VTT at 1.28V if not already set there. You could also keep the same speed but with 6-6-6-18 timings instead. or a higher bump in frequency with 7-7-7-20 or 21

Yes I heard about the uncore bug. It was in the Gigabyte article for example. I personally did not experience the same thing. My OC was unstable with 2x+1, but was stable at 16X, guess it depends on the chip.

[toohot]

Good morning N-Ster or should I say good afternoon.Idle temps are good this morning due to room temp @19. 40 41 40 40c. I will join the club soon as thermal paste arrives.What frequency should I set memory at 7-7-7-20.and which tRAS level is better 20 or 21.And regarging the unicore bug,do you know what the bug was ?. also remember I only have tested for 15min using IBT @ max ,it needs long testing with prime95.Also I find that BSOD error codes helped me.I got the list of the web.And I would like to know what the 2 Gold stars I received for.

[n-ster]

the "bug" is that the CPU just prefers it, no ACTUAL bug.

Try maybe 1810 at 7-7-7-21. sometimes it is more stable with 20, so you might want to try that too. mem @ 1.64V VTT @ 1.28V. If that doesn't work, try doing 7-8-7-20 or 21 or 23 or 24. meaning if 7-7-7-20 not stable, go to 7-7-7-21, if thats a no-go, then 7-8-7-20, then 7-8-7-21 and so on and so forth

the 2 gold stars under your username are just your postcount....

I no longer have stars as I have too many posts, therefore I am eligible to a custom title. I haven't decided on it yet. The stars above the car is because I miss my stars, so I added it to my profile pic

[toohot]

Ok. I will try the above settings and keep you informed.

[toohot]

currently tRC is set @ 34.What should i set that @.does tRC 20 sound ok or leave as it is.

[n-ster]

Minimum tRC should be tRAS + tRP. I recommend that for stability, for now, it should be tRAS + tRP + CAS Latency at least.

We can tweak these settings later. most important for now is CAS, tRCD, tRP, tRAS, and Command rate

[toohot]

so tRC 35 = 21+7+7? currently 34

[n-ster]

if it is clse enough, ie: 34, in this case just leave it at 34

I will be reading http://www.xtremesystems.org/forums/...d.php?t=263183 to see if I can learn anything

note: sometimes tRC is best left higher

[toohot]

ok no go an all fronts.Volatage set @1.64
1.1810@7-7-7-21 boot fail waning due to overclock voltages
2.1810@7-7-7-20 as above
3.1810@7-8-7-21 as above
3.1810@7-8-7-20 beeping computer (fast long peeps)
4.1810@7-8-7-23 as above
5.1810@7-8-7-24 boot fail warning due to overclock voltages

Please see link.they like cl8 at higher vtt

[n-ster]

Well than... bump mem voltage to 1.7~1.74V and VTT 1.3V~1.45V. Try 1810 7-7-7-20 with that.

[toohot]

Thats a worry! coudl that damage ram memory at that high voltage and as for increasing vtt will that also increase temps?Sorry for being a pain.

[n-ster]

naaa

WINTEC AMPX 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 ...

DDR3 can handle 1.8~1.9V easily, so 1.7V is no problem. Reason why RAM is such low voltage for lga 1366 is that on stock, when VTT is 1.2V, it is dangerous for the CPU to have higher difference than 0.5V between VTT and mem.

If you are scared, stay at 1.7V, as that is REALLY safe IMO. VTT shouldn't increase temps, and if it does, it isn't by much.

[toohot]

The wintec is rated @ 1.9 volts.I will give it a go @ 1.7v and cross my fingers.I just spent 1 hr cleaning the dust off the heatsik and fans.I also untightened the two screws on the heatsink and gave it a couple of little twists then retightened the two screws,but it did not help lower idle temps.actialy i think it raised it alittle but I'll haven't put the side cover with fan back on.
