***The Official Core i3 Overclocking Thread***

I think my PC might have done an update last night. It had rebooted when I looked at it this morning. Was about 2 hours through before I went to sleep. :confused:

All my voltages are stock apart from Vcore and Memory.

Didn't need to touch the others to hit 4GHz, just manually set them all to stock settings so the BIOS didn't auto ramp them.

Will do 4GHz @ 200x20, 4GHz QPI (8GHz), 1600MHz mem @ 1.30625V (Vcore), 1.66V (Vmem).

Easy as that.

Running with 1.64 on the DRAM and 1.1 on QPI/VTT gives a 0.55V difference there though - I thought it was important to keep those two within 0.5V of one another?

trying to see how low i can get vcore on stock speeds, am at 1.152 volts atm. How low do you think the chip will go?

And regarding the other end of the spectrum, at 3.8ghz, with stock cooling, and stressing with LinX, temps reached 74c, is that a safe temp or a bit too toasty?
 
What you using for monitoring temps?

am currently using CPUID Wardware monitor, but not sure if it's accurate or not.

Had it up and running at 4.4GHz at 1.35V last night. Only testing I did was running Crysis. Didn't leave it at that for long though as only got stock cooler. Also not sure if there is really any benefit to going that high.
 
Im using realtemp.

Have now set the vocre to 1.0 volt (BIOS) and has booted into windows, am now stressing with LinX CPU-Z is reporting 1.024 volt

Off topic.

Just for you Wayne. :)

Will order the mounting kit for my Mini Ninja soon and going to change the front fans for some nice new ones I think.
 
Ok im getting some weird settings with my i5 650

Bios reads:

BCLK 160
CPU FREQ:4001
MEMORY 960
VCORE 1.248
DRAM VOLT: 1.536

UNCLOCK CORE RATIO X15
SYSTEM MEMORY MULTIPLIER 10

MEMORY FREQ 1066 1600

Its got 1600 stuff in it, weird. help
 
Jesus, how trying 0.9500 vcore in bios, and is reading 0.960 in CPU-Z, surely the vcore cant get much lower???
 
0.9500 vcore passed, tried 0.9250 but that failed after 3 mins of LinX. Am now going to try 0.9500 vcore again, but also lower QPI voltage to 1.050, to see if i can shave a few work degress of the load temp. What other voltages could be lowered to help with heat? Current temps on both cores never go about 50c atm, and the room temp is 23c, all on stock cooling
 
Hi guys!
I'm running an 13 530 on an Asus P7H55-M Pro Intel H55 with a Noctua and Corsair XMS3 4GB 12800C9 1600MHz memory. Now my problem is I can't get this thing stable with either IBT/LinX or P95 when OC'ed.
The scrennie below also shows some weird figures. Can anyone shed light on me as why this figures are not what they're supposed to be?

My questions is
1. Whats the -0.98 V for?
2. How come my QPI Link is 4414 using a 20x200 ratio?
3. Is this Vin1 and Vin 3 represent the voltages for my RAM? If they are, how come Vin3 is showing as having a 1.07 volts when I set the DRAM voltage to 1.7?
4. Could all of the above a bios or a mobo problem?
Another thing i've noticed is that, Everest, Real Temp and HWMonitor are reflecting different temps.

Any help would be highly appreciated.

i think you want it about doubel your memory speed, so 3200mhz, try manually setting it so its a 3200hmz in the bios
 
Those voltages might just be because it's a new board and the software isn't reading them right. Wouldn't worry too much about them.
 
Well, this thread has been too quiet.

I wasn't going to bother with OCing for some time, but just once I'd like to push an OC on a CPU. So, I bought a slightly better air cooler, and will this weekend be trying for 4.4GHz on air.

I would also like to be able to get my memory at 1600MHz, but this is either not going to happen, or will happen with loose timings such as 10-10-10-XX. 1600Mhz probably wouldn't be a problem if I upped the voltage above 1.6V but I have heard higher voltages on memory with the I3/I5/I7 can kill em.

Do I need to OC? No. Will I notice the difference? Probably not. But as long as I leave it at stock or with just a mild OC, I will feel like I am wasting it.

Sometimes a good undervolting can be rewarding ^_^.

Later on I am building a rig to run a 1000fps counter strike source server, and I am planning on a simple yet clean i3 build for it.
case - check
psu - check
hdd - check
gpu - not required
cpu - i3
mobo - yet to decide

cost... £200

undervolt that puppy and before long the running costs make it cheaper than renting one (we are having fibre installed soon)
