hi are these setting ok guys i used the ai suite software to get this OC but im sure i read on a another post that DDR Voltage should be 1.5 ?? but mine is higher and should the bclk frequency be 104?

tried doing a overclock manually following a guide i found but it didn't work pc crashed hope i have not buggered anything up :eek:

anyone got this board and a i5 2500k know what settings i need to adjust manually for a 4.5ghz OC?

Try to avoid overclocking with AI Suite II and try avoid clocking the base clock.

The UEFI Bios is really quite simple to use, especially for overclocking.

For basics just put the multiplier up to 45, leaving the bclk at 100 (100 x 45 = 4.5ghz). Perhaps take the LLC off auto and put it on U.High.

For now leave voltage at auto, fire it up and stress it (P95 or IBT) use cpuz and coretemp and take note of the vcore in cpuz and the VID in coretemp. Write them down (hold onto the VID for when you want to set an offset) and enter the voltage manually from the vcore reading, boot stress, if it passes go back and drop the voltage a notch, rinse and repeat until the system is unstable under stress (BSOD or hang ups) then up a notch a re-test stability.
 
Thanks for that
Started at 1.42v core (vid was 1.37) got it down and stable at 1.35v wont go any lower BSOD occurs ran prime 95 for a hour 69c average max temp across all four cores warm room 24-25c during the test DDR voltage at 1.5 blck frequency at 100 think these temps are acceptable?

anything else i could tweak to get voltage a bit lower ?

cheers.

Yeah you could try putting LLC to extreme, but in my experiance it made very little difference. Temps of 69c is fine though it doesn't leave much headroom for a higher clock without a cooler upgrade. If you are happy with the voltage you can now set an offset if you wish :)
 
ok will try llc settings im happy with 4.5ghz tho :) just wondered whats the offset feature for remember seeing that in bios (on laptop at the mo) will have a look later do i set it to the vid i wrote down at the start ?


thanks
 
You calculate the offset from the vid.

Basically it will reduce voltage while the system is not under load working with speedstep.
 
Hello and good going Raggs. I hope you don't mind me jumping in here in your thread for any advise/recomendations etc. I've just upgraded to the same CPU, mobo and memory as yourself with the Gelid Tranquillo CPU Cooler(which I'm still finishing off puting together :) ).

My bios changes are:
Cpu Volts: 1.368
Cpu ratio: 42
BLCK: 100
Memory set at:1600
Ram Volts: 1.6
LLC: V high

I noticed that my CPU temps are pretty high in Core Temp when compared to Asus Prob, is this ok?

Will run some more tests etc. Many thanks

ASUS probe is probably measuring the thermal probe which sits below the CPU slot on the actual motherboard!

So you will get a difference between them both. As far as I am aware the temp you need to worry about is core temp, and shouldn't stay above 70c for prolonged periods of time!

Try HWmonitor and you will see the core temps and the actual thermal readouts on the MB !

Click to expand...

hey i have the same temp differences when comparing asus software to core temp hw monitor ect.. sometimes it even tells me fan cpu fan is at 0 speed at times :p but i can clearly see it spinning through my windowed panel i would trust hw monitor /core temp over the asus software

Recommended memory voltage is 1.50v btw might wanna drop that down.
 
Rgr and many thanks chaps; I will reduce memory Volts and download other Temp software and might have a go at sticking the CPU heatsink on again just for peace of mind(was rather knackered when I did it last night).
 
Thanks for info and link Thermaltake.
I reduced the CPU Volts and temps on IBT on the max test to keep temps down.
I did re-set the CPU heatsink, but not much diference in temps.
One problem I have is that my room is warm as it is at the top of the house + faces south; I might need another cooling solution if I want to go further in overclcocking, what do you chaps recommend?

Thx

Thanks colinmcr for link. I think I need a better colling solution to comfortably get my CPU to 4.5Ghz..I'm not sure if the extra OC is worth the "bang for buck". My overall limiting factor on my system is my GPU I think (I'm into flight sims). been toying with a Antec Kúhler H2O 920 as I figure fans blowing air is limited by my room temp
