HELLO ALLLL :comp:

Since the members on this forum are so awesome, I was hoping some of you can give me some info.

I'm oc'ing my 2500k on my asus p8p67 deluxe board. These are my settings in BIOS. I'm getting stable temps and running prime95 without any problems.

My question is this: Let's say I upped my cores to 48 or even 50, when windows 7 loads, it stays on the "Starting windows screen" and freezes.

WHy does it do that? Also if you guys have any forums for overclocking the 2500k that would be aaaawwwsome! :attn:

Thanks guys!

With the multiplier at 48x, the Vcore will probably need to be in the 1.400 to 1.425V range. Set CPU Voltage to Manual Mode, adjust the voltage to 1.415V or 1.425V, and set Load-Line Calibration to Ultra High.
 
haha intersting!. Ok I'll try that.

FYI, I previously did something real stupid and set my cpu voltage to 1.8 and fried my sandybridge cpu. haha

Just wanted to make sure that these are safe voltage settings. =X
 
Intel has never published the "absolute maximum" Vcore / Vcc for the 9xx variants, so we can only go by what's listed as the max. in the VID Voltage Range, which is 1.375V (~ 0.2V higher than the average VID of 1.12 - 1.15V).

IMHO, 330-350 should be MORE than enough on the vrm-freq for a 2500k

as far as VCCIO, depending on what speed/timings of ram your running, you may not want to leave that on auto as well..

We do a lot more with COMPLETE system specs :D

and :welcome: to the forums.

edit:.. also, I would not use the highest setting of LLC, It may not be the same, but on the asus board i used the highest setting would actually give more voltage than i wanted.. however the 2nd highest setting with offset voltage, adjusted with either -/+ in the way I needed would give me minimal to near 0 vdroop on load. with the same setting on manual set voltage giving me just a slight vdroop under load, which you can compensate for if you got the manual route and plan on leaving speedstep and c states enabled.

Welcome! I ran into some problems building my rig so when I finally got it up and running I didnt feel like messing with it at all. I went into TurboV EVO(in ai suite 2), clicked fast in the automatic oc tuning and bam, 1 minute later 4.3ghz oc freaking awesome!

Im going to go in and manually do it when my new bracket comes in for my cpu cooler, but it was nice to oc without having to do anything haha
 
Yeah, the auto overclocking on asus boards seems fine, however, you can reach those speeds with less voltage, thus lowering max temps.
I run 4,5Ghz on 1.280vcore in bios. If I use auto it will pass 1.30 easily increasing max heat with a couple of degrees.
