Hi All

 

Having recently got a new set up, I wanted to overclock it. Unfortunately I'm an absolute beginner at this never having attempted it before. I've read the guides on here and elsehwere on the interweb (probably read far too many "guides"!!) and got thoroughly confused.

Anyway I think I've got a stable OC @ 4.5 with a core voltage of 1.184. Currently running a stress test with AIDA64 (2 hours and counting) with max temps hitting around 70c.

My question is should I try and go further and should I just be changing the multiplier and core voltage and leaving everything else alone?

My specs are in the sig and the system's water cooled although I'm not sure how good my paticular system is.

 

Many thanks for any advice

 

Regards

ps and yes I am as old as my avatar (just not as wise!!)

I don't know Word Not Allowed, it looks good to me. According to this, that's not such an uncommon full load Vcore for 4.5GHz and IB. Temps seem normal too for a non de-lidded 3770K

If you have a good little better then avarge IB chip do @4.5 1.15-1.20 and Max 1.3v for a really bad one if need more vcore its something Else thats wrong.

@4,8 normal is 1.3-1.38v , @4.9-5.0 1.35-1.47 if you need more vcore you have a really bad chip.

If you try to run +1.5v you need a really good cooling

 

Hi Guys

 

Many thanks for the replies

 

@Word Not Allowed, I did read your guides (more than once ^_^ ) that's why I thought I was on the right track. Also saw a YouTube video from Asus saying that Prime95 shouldn't be used for stress testing as it wasn't validated for IB 64 bit systems and could potentially damage the system? My water cooling is a COOLIT ECO II FAT BOY PUSH/PULL CONFIG LIQUID CPU COOLER. Any good?

 

Anyway my test crashed after just over 6hrs so I've upped it to 1.190v and tried again. Haven't disabled HT, should I? Also haven't de-lidded the CPU and to be honest I'm not overly keen on doing that.

 

Sorry for the newbie questions but one more

Should I disable the C states? and if someone could explain offset...... :wacko:

 

Many thanks as always

HT you can disable most here do that.

De-lidd, not if you run up to @4.8 and HT disabled

 

I run with HT off , have no problem with heat(phase change) and can run @5.1 1.34v but run @5.3 1.45v

IB needs good cooling

Hi Westman

 

Thanks for the advice, I'm guessing you have better cooling than me!

 

Anyways, still trying to to get it stable at 4.5. I'll try disabling HT and see how that goes. Once stable I'll try for higher.

 

Be back for more advice then!! :rolleyes:

 

Thanks

Yes, I need 1.33V for 4.5 and 1.50 for 5Ghz (de-lidded and good temeratures). As @Westman said, it depends on every each chip.

I have a 3570K at 4.3Ghz at the moment and the vCore under load is 1.368.

 

Guess I got a bad chip, even now I get CTDs in FSX because of it :(

Still haven't had offset or C states explained

 

Cheers

C3 and C6 are CPU deep sleep mode and need to be disabled if you are using offset mode. They also need to be enabled if you don't use offset.

To find your offset value you need to find VID under load. You can find this with Core Temp, just note VID value under load(start stres test for example and watch for value). Keep in mind that showed VID will not be 100% precise. and can vary.

So, let's say you are stable at 4.9 with 1.4 vcore. Your vid is 1.3511 on idle, and 1.3811 under load.

We will take value under load, and then calculate difference from this value to 1.4 value of Vcore. So, in this case - 1.4 minus 1.3811 = 0.0189. Becouse you can increase/discrease offset value by 0.05 if i remember well - 0.0189 means + 0.020 offset value(offset can be + or -).

1.3811 + 0.020 = 1.4011 and you are stable at that value. So, with offset, you will get 4.9GHz and 1.40 Vcore on load, and CPU will go to 1.6GHz and approx 1.05 Vcore on idle
