Asrock Xtreme 4 + 2500K @4.7

My 5.1GHz only gave 7.2sec in superPi but the improvement in CinemaBench for example is significant from stock to 4.8GHz.

i have found that with quick sync and the improved clock, i can now use media converter 7 and convert a full length film from a 12GB MKV file to a 600-mb-2GB H.264 AVI file in under 20mins. thinking back to my old X 3.8GHz AMD system, that was nearly an hour to do the same job.
but for gaming its meant i can up things a tiny bit in some games but thats about it. maybe things are smoother, but nothing i would say was mind boggling.

what was you vcore/temps @ 5.1GHz and was it 8 hours prime stable?
 
ok, so far managed to get it to post @ 4.7GHz without problems (4.8GHz and 5GHz posted but failed to load windows). the problem is, it wouldnt post with spread spectrum disabled and i didnt get what to set to 200 (other than current core limit). now its loading into windows i have the same problem i had before, WEI runs it @ 4.7GHz but prime fluctuates between 4GHz and 4.2GHz so i have no way of knowing if its prime stable :confused:

and cinebench was @ 4.7GHz for the openGL test

but drops again when running the cpu test

im guessing either there is a turbo option on somewhere or its throttling for some reason :(

(Turbo Boost is currently set to auto just changed it to manual to take screenshot of settings)

Level 1 LLC for 4.8GHz @ 1.38V more likely will be Level 5 to get pass the post

I am going to order this board next monday http://www.overclockers.co.uk/showproduct.php?prodid=MB-051-AK and get rid of my crappy z68x ud4 b3 (not a very good board) and will order a new i7 2600K retail too. I brought mine i7 2600K oem from the shop (big mistake as it probably very poor chip as well) unstable at 4GHz even left everything on auto default on the bios. Not very happy.

Just buy the board first and run some tests on the new board. And if you are then not happy, get a new chip. You never know it might have been the board holding you back, and it might save you some money.
 
Paradisiac, the thing you couldn't find and I couldn't remember is the Turbo Power limit.
Leave it at manual and change short and long power to 200W. (people even set it at the excess of 250W).
If you get a BSOD than bumb the Vcore another step (just a fraction).
Test for stable max Turbo with Super Pi not Prime.

Oh, and if you are hitting 75C temps, clock it down and get a better CPU and thermal paste. You really do not want to be as high as this.

it runs at around 58-63C when gaming and using things like video converter doesnt go over 55C.
is there any way to test prime stable? there must be a way to disable this turbo thing, because if you do the auto OC it runs at full speed in prime.
4.6GHz seems to be the highest so far i have got without a BSOD up to 1.35v.
any ideas why it wont post with spread spectrum disabled?
do i leave long duration maintain @ 1sec?
 
Yep, leave that @1s.
Spead Spectrum is really a gimmick that is for use with a lot of PC and a lot of magnetic interference around. Do you have something that could cause it?
This should not affect your day2day usage really and can be left enabled.

why do you want to disable the turbo? and what do mean here:

when i run prime when i use the auto OC it primes @ the speed it set it to all the time ie 4.6GHz, but if i do it manually, prime fluctuate between 3.8GHz-4.2GHz no matter how high i set the multi.
the same with cinebench, i get lower cpu scores doing it manually than i do on auto, because the multi fluctuates, where as on auto the multi goes up to the max and sits there.

Check that after modifying power limits, usually there is not enough power hence the cpu clocks down

ok kool, will give it a go tonight after work :)
i got it to post @ 5GHz which in itselft im suprised at as with auto i couldnt even get post @ 4.8GHz. i just went to a black screen when trying to load windows, so im not sure if thats a lack of vcore (1.38v) or something else.
 
Using youtube last night I found a really good video specific to the Asrock boards for overclocking, was for the P67 as opposed to Z68 but same bios options.

One thing you need to change is the power limit. I noticed at first on my 4.6ghz it keep moving around. But when you up the long duration power limit from 95W to 200W and short to 230W it stays bang on 4.6ghz when not idling.

Also use level 4/5 for load line calibration.

Using these methods + offset voltage along with the "normal" options I managed to get 4.6ghz at 1.26 volts so it runs really cool :D I am quite lucky with my CPU again it seems, my Q6600 Go did 3.6ghz on stock volts.

you got yours stable with 4/5? i got nothing but BSODs with anything other than 1 as my Vcore jumped around loads.

Thanks will do but before buying a new board, Can you tell me what is your correct setting for 4.60GHz for vcore, dram, qpi/vtt, which level on LLC, do I need to set both '200' on Turbo Power Limit (Watts) and Core Current Limit (Amps) or leave it on Auto ? As you had the same board as mine Z68X UD4 B3 and what bios version do you have ? Mine is F7.

Thanks.

Thanks.

Running the F7 bios also myself and my settings are as follows...

Vcore 1.35v
Dram 1.55v
VTT 1.1v
PLL 1.8v
LLC 6

I've not touched the turbo power limit or the core current limit, so I guess both are on auto, but I will check for you.

does your run at full speed constantly when prime testing?
 
Different boards have different power management so can't directly compare the settings. BIOS in gigabyte can have different limits set by default anyway.
