Help Overclock i5 2500k?

post #1 of 5
Thread Starter 
Hello guys,

I just found out this brilliant site and I would like to ask for a help with overclocking my Intel i5 2500k

My MB is: MSI Z77A-G43
and just bought a Coolink Corator DS cooler (Im hopefully going to install it tomorrow)

I checked some tutorials on OCing but there are many different options, some are the same as in the tutorials and some of them are missing. and I would like to not make some bad changes in the BIOS.

I have installed ClickBios 2 so I can post some screens of the options available:





Basically I would like to go for 4GHz or 4.5GHz, I think this should not be a problem.

I know that the most important option is probably the "Adjust CPU Ratio" which is the multiplier, I would like to go for 40 or 45.

But there are some other options that Im not sure about because different tutorials show different settings.

Internal PLL Overvoltage - (default is Auto, from what I've read it could stay on Auto?)
EIST - enabled
Intel Turbo Boost - default is enabled, some say enabled some disabled
OC Genie Function Control - default is By BIOS Options
My OC Genie - default is Default
DRAM Freq - default is Auto (is this for RAM overclocking?)
Extreme Memory Profile - default is Disabled
DRAM TIming Mode - default is Auto
Spread Spectrum - Disabled
CPU Core Voltage - The most important one, default is Auto, could stay on auto for lower frequencies?
DRAM Voltage - Auto

Then there are the CPU features:
Limit CPUID Maximum - default is Disabled, should stay this way right?
Intel Virtualization Tech - default is Enabled
Power Technology - Custom
C1E support - Disabled
OverSpeed Protection - Enabled
Intel C-State - Enabled
Package C-State limit - Auto

I would really appreciate if someone could help me with these settings as Im newbie in this.
And basically after setting this options, do I just change the CPU Ratio to lets say 45, and check with the default voltage?
Then if its not allright, add and test again?

I downloaded the Prime95 tool for testing as recommended, when Im dont in the BIOS, with what settings should I run the tests?

Thank you in advance, I hope its not too much questions smile.gif

Great thing about SB is they overclock pretty easily, I only adjusted my multiplier for a 4.5GHz OC with speedstep enabled cause I don't need to run @ that speed 24/7.

See this thread alot of useful info.

I checked that tread, but those settings are totally diffrent from what I see in ClickBios.
Could you help me with the settings from ClickBios, basically I read which are doing what, but different settings in different tutorials are kind of confusing.

Should I touch the DRAM settings as well? Or are these RAM related?

Basically What I need is to set the CPU Core Voltage from Auto to 1.20V and then bump up the CPU Ratio to 40-45? How do I know if the Voltage is enough? When it boots or do I need to run the tests?

Then there are the CPU Configurations and first on the list is CPU Ratio - Auto, where in my case the Ratio is the multiplier, kind of confusing.

Im curious about these settings:
Intel Turbo Boost (I guess its the same as Turbo Mode in the thread you posted) - Enabled
Internal PLL Overvoltage - Auto by default, Disabled in the tutorial thread
C1E support - Disabled by default, Enabled in the tutorial thread
OverSpeed Protection - Enabled by default
Intel C-State - Enabled by default
Package C-State limit - Auto by default

Hey man, basically just use that thread as a guideline. I haven't pushed my chip beyond 4.5 so I never had to make any additional adjustments besides the cpu ratio. I'd suggest to try starting with a ratio of 41, then boot into windows and run Prime95 for about an 1hr then gradually make small increases to the ratio till you're at 4.5, then run Prime for a couple hrs to make sure you're absolutely stable. Once you've begun getting BSOD/crashes at whatever ratio you've currently set then it's time to start making voltage adjustments. Every chip is different so what settings may have worked for some may not necessarily work for you. Up to you to figure that out. Pretty sure my chip can go higher but 4.5GHz works well for me.

The Dram Freq you can adjust it to whatever freq. ram you have but you can check cpu-z in windows to see if it's already running at the correct speed but it's no prob to set it in the bios. I've never played around with dram timings so can't really help you there. It also does nothing to help OC the cpu. Also you should fill out your rig specs whenever you get a chance so other members can assist you better.

I'd also suggest upgrading your cpu cooler to one of those AIO coolers from corsair/nzxt/swiftech for better OC results.

Hey, yea I will follow it but there are some options I dont see available, hopefully they will be in BIOS.
4.5GHz is good enough for me as well. When testing, should I run some default test or adjust the settings based on the thread? And would 15 mins be enough per test? Thats what he suggests.
And when getting crashes, how much voltage should I add? And when I add it, log into windows and test again?
And also, when starting at 4.0GHz should the Voltage stay on Auto or Manual and set to 1.20V?

My friend told me that when I OC the CPU, and when RAMs are set to Auto, the frenquency will change accordingly to the CPU frequency. So should I set it to Auto or Manual and 1600?
When I check now with CPU-Z the DRAM frequency is at 666MHz, thats probably because its set to Auto and it underclocks itself. Just as CPU is now at 1.6GHz.
So thats why Im worried if I dont change it from Auto, it will go to 2GHz+ and maybe get damaged? I dont really know how it works.

Also what about Turbo Boost? Disable or Enable?

I totally forgot about that, here are my specs:

MB: MSI Z77A-G43
CPU: IntelĀ® Core i5 2500K
GPU: Sapphire ATI HD7850 OC
RAM: 2x4GB Kingston 1600 Non-ECC HyperX XMP Grey
HDD: Seagate Barracuda 750GB
PSU: Be quiet! Pure Power L7-530W 80plus
CASE: CoolerMaster Elite 431
FAN: 1x Gelid Silent 12 - Rear

I thought this Corator DS is pretty good, at least thats what they recommended me when I asked on a forum and from youtube I think it might do its job smile.gif

One last thing, when changing the cooler and working with the MB (because I have to take it out of the case) how can I ground myself? I dont have any of that anti static wrists or anything. And my case is painted black, I cant see any unpainted metal so what should I touch? Thanks smile.gif
