Overclock I5 750 Advice Needed

Hi everyone!

I need some tips in order to overclock my CPU. I did a Prime95 on stock clock speeds and both done a "Blend" and In Place Large FFTS Max Heat and Some Ram Tested.

Both Results after around an Hour gave a max temp of 68.

I've know adjusted the Bios to get me 4gig and 1.35 Volts.

So at this stage looking for any suggestions?

Thanks.

Rob

If you have already got 4ghz what more do you want to achieve?

Hi Tom.

What would be a safe temperature to have? For Starts??

Also with this Cooler I have different fan wires two Blues and a Black would this make the fans go faster? Is there a way to change the fan speed in Bios?

68C is fine id leave it at its current clock personaly (rule of thumb is try to keep under 70c as best as possable, some processors are ok a little hotter but i like 70 as an all out max), running games and things it usualy wont get up to the prime 95 max, for example i get 65C with prime 95 on my e8600 but in games the max ive seen has been about 57-58, if your at 4 Ghz you wont realy need any more power to be quite honest.

Yeah thanks,

But 68oC this was on Stock Clock Speeds.

With Prime95 What Method Of Stress Test Should I use?

What Bios Settings?

Thanks.

Edit These are the settings atm:

AI Clock "D.O.C.P"

Dram OC Profile DDR3 1600mhz

CPU Ratio 20x

BCLK 200

Dram Freq 1600mhz

CPU Voltage 1.325

Dram Voltage 1.75

CPU Spread Spec "Disabled"

PCI Spread Spec "Disabled"

Going to run prime95 for Half An Hour and report back.

if 68 was on the stock clock spped i wouldnt overclock untill i got the temps under control, are you sure you aplied the thermal paste properly?

Yeah I'm sure I did, I've got MX3 (Arctic Cooling) or I got Silver 5 As Back Up.

I've currently got MX3 and I planted a small amount in the center of the cpu and I spread ed it around evenly.

Did you set the voltage to 1.35v for stock speed too?

Volts is where the heat comes from, so we really need to know what volts you were running at stock?

I can't remember off hand. but as i said currently at 1.325 and max temps are quite high.

they are way over safe temps id drop it back down to stock for the time being as it will shorten your cpu life conciderably if not kill it, re-aply the thermal paste and this time put on a bit more and see what temps you get at stock once you have re aplied the paste.

I was looking about on youtube about methods in applying Compound.

1. A Blob In Center Of CPU

2. Line Down The Middle

3. Blob and Spread

Which one of the best practices is best do you think?

I use 3. Blob and Spread but with the other methods it gets spread out pretty evenly too. In the end I think the critical part is the amount you use. As long as you get the amount right, the method of application will probably mean 1 degree difference max.

Yeah for the decent cooler you have on it, those temps are wayyyyy too hot. Clock it back to stock for now, don't want to break the thing!

 

[RobCharles1981]

Thanks All.

Ile try the "Blob" Method and see what happens there.

 

[RobCharles1981]

I've done the "blob" Method And I loaded Bios Defaults and at stock speeds and I've tested Prime again using FFT Maximum Heat:

Looks about right tbh, what speed are the fans running dude? You should do your tests with them connected to a melox so you know 100% they are at 12v. Once you get a decent clock you can decide either more heat or a lower clock and less noise.

Hi Tom

They are running at 1240-1259 rpm

Thanks.

Tom ?

Rob?

How are we son?

Are my fan speeds correct do you think ?
