Intel overclocking quick help?

post #1 of 27
Thread Starter 
Got a i5-2500k

bios multiplier stable at x47 with bclk at 102.2MHz, thing is when i boot computer CPU-Z only shows my cpu at a x16 multi or a x32 depending on if there is a load or not... even my rc tweak it won't change my multiplier.

Any ideas as to why this would be happening?

computer specs are below.

Load it with Prime95 and report back. Also make sure turbo is turned on.

If it is only going to 3.2, then you don't really have it stable at 4.7. First off turn the BCLK back to 100 - no sense overclocking that with a K chip - and then post back with your BIOS settings (screenshot the BIOS page, or list out the stuff from the CPU page. Sounds like you don't have the multiplier set correctly, or have set something to disabled that is preventing the chip from going to the turbo freqs.

So i cleared cmos just to start over. basically my goal is to get 4.7+ghz out of my specs as well as my ram at more than 1333mhz i knows the ram should be able to get 1600 so im wondering why. none the less lets start with the cpu, here are my bios screenshots
First page/main page x3




CPU performance page


CPU Configuration Page x2



I hope we can get some where if more pages are requested there is a lot more i can printscreen from bios, Asus ROG boards are full of them.

So where it says "Maximum Turbo Ratio Setting" on the first page - set that to the speed you want. So for 4.5GHz, set 45. I'd start at 4.4 or 4.5 and work your way up to 4.7.

In the Turbo Parameters section you probably want to change all those Power Limits and Current Limits to something on the higher end of the scale (different boards have different kinds of values there), although you can start with them on Auto and get your feet wet first.

You should also find a setting somewhere (not in the shots you posted) where you can set it to use the XMP profile for your RAM. That should get it to run at 1600.

Initially you can just leave the Vcore at Auto, but monitor the voltage under load with CPU-Z and make sure it isn't crazy. Once you go over 4.5 or 4.6 you'll want to set either a manual or offset voltage, instead of Auto.

thank you,
as for XMP MANUAL or AUTO setting it is under the first image Ai Overclock Tuner.
Yet when i set the ram to x.m.p 1600mhz my pc wont get past the cmos check during boot up.

My board also does have a preset 4.6GHz overclock as well as a 4.2GHz (first image first setting CPU Level Up)
Yet when i set this to 4.6GHZ everything boots fine and dandy, but my CPU-Z still registers x16-x32 multiplyer and a max of 3.2GHz out of my CPU.

Im going to mess with the settings a touch take a few more screen shots and reply soon, looking forward to some more aid in this clock.

Just don't get it. I'm going to try more tomorrow.
But its almost like my cpu is acting like its just a 2500. yet i had a 2500 and i when i did i didn't even have the ASUS bios option of 4.2GHz or 4.6GHz preset overclock, that is why i bought the 2500k so i was able to overclock, was happy with the preset 4.6GHz overclock, just assumed it always has been working. yet when i went to go and make my CPU pump 4.8 or 5.0GHz i realized that my multiplier wont even go past x32. im wondering if i there is a default cmos (bios button on back of my pc to clear bios(cmos)) setting keeping my multiplier from going anymore than x32, wont even go to x33 to make it a 3.3GHz as specs say.

Try doing it manually, instead of with the Preset. It's really as easy as changing the one setting (Turbo Multiplier), at least for moderate overclocks.

Try changing the setting for Memory Frequency from Auto to DDR3-1600 manually. That's what I had to do with my Asus board - it didn't like the XMP profile.

The moment my board puts the ram to 1600mhz in any fashion it wont boot without clearing cmos. Not that it may matter, but intel's specs on the i5 i own says its only good for the 1333mhz and the one under. maybe that is why.

as for changing my turbo setting i have even to 34 and it does not change a thing once i am booted. my cpu multiplier has even gone down to a max of x31 during prime95 now, well im off to write a test, ill be back later and try again to get even a step above stock in overclocking... it should be possible to get at least 3.4GHZ outa this 2500k on my board frig its a ROG board has lots of potential in my set up to overclock.

Found the fault in the RAM, was the "MEMORY BANDWIDTH BOOSTER" with it enabled it would not work in 1600MHz mode. with it DISABLED my ram runs flawlessly in 1600MHz mode.

CPU is still a hassle.
