I'm trying to push my i5-750 as far as it can go and I will do the same with my Mushkin Redline when I get it.

If I try more then 4,5GHz my PC won't POST at all so I got to clear my CMOS. If I try 4,3GHz I can't get it stable at all. I went all the way up to 1,39V with no luck.

I thought I'd stop there because I didn't want to go too far. What volt would you guys say is the max? Intel says the absolute max is 1,55 volts.

If you need to know my specs look at my awesome signature I made a couple of days ago. xD So can you guys help me pushing my CPU to it's maximum?

I'm sorry if there's a separate sticky for this, but I always think it's better to get opinions considering the specifications I got. Thanks in advance.

Post up full board and component specs plus ALL info from your extremetweeker in the bios.

But tbh you have a very good clock for that cpu anyways.

What do you mean with all board and component specs? Do you mean voltages, speeds, etc.? I don't understand how to say I got an i5-750 more detailed. I'm confused. :S

Here's all my settings. I'm posting them in the main thing too.

Target Speed: 4022MHz

Multiplier times 20.

CPU Frequency = 201

PCIe Frequency = 104. (Heard it might help a bit if you up it a bit from the stock 100.)

QPI Frequency = 4.270GT/s

Extreme cooling is disbaled

VDroop is off.

Both Vcore voltages are at 1.31250V

RAM voltage is 1.65V.

Bootup CPUVIT is 1.400V

PCH is on auto.

CPU PLL is also on auto.

NF200 voltage is set to auto.

DIMM 1/2 DQ and the rest of them are +0mV.

CPU PWM Frequency is 800KHz.

VIT PWM Frequency is 240KHz.

DDR PWM Frequency 240KHz.

CPU Signal 1, 2, 3 and 4 are set to auto.

CPU PCIe 1 and 2 is set to auto.

DDR Signal 1, 2 and 3 is set to auto.

DMI signal is set to auto.

PCM signal is set to auto.

So that's everything.

Both Vcore voltages are at 1.31250V This doesnt sound right.

Can you write down EXACTLY what they say in the bios and what the values are please dude.

Including the CPU config and Ram Config sections.

Take pictures of the bios pages if you want, just make sure they are clear.

I can't take pictures because I don't have the transfer cable for my W995. But I mean that startup VCore and the normal Vcore are both at 1.31250. I'll write the CPU and RAM config soon. A bit busy now.

Got pictures of it all (Which I can't post.) So hang on, I'm writing them all down now. Gonna take a while, though.

Is there any spread spectrum controls?

What voltage is that RAM designed for (check the back of the RAM, put the voltage up to that value, maximum of 1.65V). The Vcore can be pushed to about 1.35 (both bootup and eventual) without worrying about temps too much. Try bumping the RAM dividor down a bit, slackening the timings to 9-9-9-24 perhaps.

4.0+ is pretty good to be honest.

The RAM is designed for 1.5V and I believe it's 1333MHz RAM and the timings are 9-9-9-24 at stock I think. I'm not sure, because I can't find the specs listed anywhere and it doesn't say the name on it so my brother 'thought' it was the RAM with the specs I listed. I know it's 1.5V, though, because it says so on the back of the RAM. So you mean I should set the VCore at 1.35V and push the CPU as far as it will go?
 
What ram you got exactly, cos to me it sounds like you may need to invest in some quality stuff.

You also need to realise what you have already is a good clock, you need to get in and learn the bios yourself dude. As the final little tweaks is only something really you are going to be able to do with a lot of time and effort. You need to get to know your system better than the back of your hand

ps. I post when I can, its a big forum not just me fella

I've already bought 4GB Mushkin Redline. Getting it sometime this week. It's at my brothers place. And I have no clue what RAM I got ATM. And I wasn't really asking about my BIOS and stuff, I would just like to know some secrets if anyone had any.

here is the best overclocking secret ever

don't push your voltage and thermals past max, just to get a 3% increase in clock speed

learn to call it quits when you reach the limits of your hardware

after you do it enough, you will get a "feel" for you hardware within the first 30 or 40 min of tweaking

I have o/c'd every "PC" I have had....and I have gotten to a point where I can tell if I have a good bin or not

the only byproduct I have ever had from trying to go for that last few points is toasted hardware or a sickly feeling in my stomach that i got "ripped off"

in the real world, bumping your clock a few hundred mhz. won't equal ANY real world performance gains

if you are o/c'ing for the sake of trying to hit records....then you bought the wrong system

if you just want to see some high clocks....go buy a celeron...an ln2 pot a cheap biostar mobo and push it until it goes up in smoke....that way WHEN it does, you will only be out a hunred bucks or so

P.S. keep in mind that the voltage regulation on your mobo is not good enough to equal the exact voltages that show up on your hardware health pages

the only way to know the ACTUAL voltages you are working with is with a multimeter and a schematic to find the proper leads

example....even on my flagship ud9....1.7 volts DRAM (BIOS page) actually = 1.664 volts on the socket

so it's very hard to walk someone through an overclock on a website, because each chip and mobo will drift to larger or lesser degrees from what your BIOS is telling you

you have a decent overclock on that chip already...that extra 200mhz. will equal nothing in day to day usage
