K so i go the BIOSTAR TForce TP45HP http://www.newegg.com/Product/Product.aspx?Item=N82E168...
now i can figure out the whole fsb increase and disabling all the energy saving ecetera in the start but im really having a problem figuring out my voltage option this is for my cpu and ram(which is being over volted) it says my vram is at 2.4!!! and iots rated fro 1.8(look in sig for my specs). so here scren shots of my bios options which i need to be decoded. Oh and im trying to get my cpu at 1.3v so i can push it to 3.5-3.8

Main overclock bios screen


under voltage configurater


Optioni get when i select cpu voltage



so is that like incrments to be added to my cpu voltage(shown in second pic)

In your last photo, yes, those are increments to add to your CPU's VID voltage (found in CPU-Z; this is NOT the voltage shown in your second pic).
First, though, you need to figure out the spec voltage for your particular brand/model number DIMMs, and set the "DDR voltage" to that value. Save settings, reboot, and run the system at stock speed. Test to verify stability using memtest86+ (at least a couple of complete passes) and Orthos in "blend mode" (or other PRIME95 stability testing program) for at least a few hours.

ya but the thing is that i can't set a specific voltage i want i can only add to a voltage

Can't find your answer ? Ask !

Adding to a standard base voltage is how some BIOSes allow you to set a specific voltage.

Quick reference, would double check your exact proc though!
65 nm upto 1.5 vcore
45 nm upto 1.33 vcore

These are max voltages these procs can handle without frying.
This isn't considering your heat solution, thermal shutdowns and throttling can affect overclocking, and at a certain point in raising voltages your gonna see a good jump in your heat if your cooling isn't adequate.

IE: i run a E4500 stock 2.2 /1.28 vcore, running for 6 months now at 3.4ghz /1.45vcore

Using an freezer 7 pro.... temps are 34-37c/ idle, 50-55c/ load, also using a CM 690 case so i got serious ventilation for all the heat.

Edit:in other words i had to increase volts by 0.175 volts to get from 1.28v to 1.45v to make it run stable at 3.4ghz, same e4500 ran at 3.0ghz with no added volts(1.28v).

Here is a question, how about asking the Guy for his VID so that you will know what his starting voltage is?

Then it's pretty easy to know where you are at, if you know what you are adding to!

Very easy to do, Run Real Temp, or Core Temp, and either should list it, and then go ahead and mention it here.

VID = Factory starting voltage for factory speed while on Auto, at stock. IE, your Bios VCore on stock is the VID.

Does your board support Load Line Calibration?

If not, you will have to test your VDrop and droop by Looking at the VID, returning to stock with EIST, C1E, and speed step disabled, and manually entering in the VID value for CPU voltage.

Boot into windows, and after a minute to boot/load windows junk, look with CPUz and note what your diminished Core Voltage is. It will be under what you manually selected in the Bios due to VDrop. The initial drop in voltage from Bios, to idle windows.

Once you did that, run Prime 95 small FFTs on all cores for at least 1 minute, and note the now even lower value found in CPUz.

List those here, and we can get your chip to whatever voltage you want, once we know all these things!

I never went thru all that!
Was trying to keep it simple steps first....and heat/voltages/ram are almost alway the 1st hurdle to certain speeds.
Watched voltage with "cpuz", and temp with "coretemp".
Speedstep seems to be an issue for some, OFF by default in winxp.
Since i am overclocking and turning up volts i'm not to concerned with it's power consumption in the first place, heat becomes a main concern though.(if your running hot because of poor cooling, speedstep is a poor solution...IMO)

45nm proc =1.36volts max
gives you 1.36v - 1.20v = 0.16v MAX that you can up the volts in bios

CPuz every ".05" steps in volts to make sure it's not above 1.36v
Was gonna buy this proc but have shifted to wanting a E8400 instead.

What i have read about the E7200 is an easy 3.2ghz without adding much voltage, volts turned up to 1.3v gets you to 3.6ghz but only with good cooling.

1.15 on idle 1.2 on full orthos load this is under core temp and cpuz
except for idle core temp shows 1.15 and cpuz shows 1.168

And Core Temp lists your VID as what? It is it's own field, and has nothing to do with actual voltage unless yer on Auto.

1.15 in core temp

1.1500 is a good VID!!

So your starting voltage is 1.1500 volts. If left on auto and on stock, it will default to this VID, and with VDrop and droop, that is what your chip needs for stock speed. (Intel usually gives it more than enough room as their safety margin to last 3 years under warranty.)

Contrary to what people say, since VID isnt the same, always, you can not go on voltages that other people issue to you, without first establishing what natural voltage your chip needs.

So what are your Goals? Starts at 2.53 Ghz, so at least 3.5!! (Since you have a decent VID, it will be pretty easy!)

here is how it goes, too. CPUz will show Real Time voltage to the Cores.

VID will not change, as it is imprinted at the factory.

Do you have load line calibration in your Bios?

And heatSink! Maybe you should go through this procedure! You list you stock voltage as 1.28 volts. Which is just a vdrop applied 1.3250 usually. Why not take a peek and look? Although most of the E 65 NM chips will be 1.3250. (and the rest are 1.3000 and 1.3125 for the most part! The worse!)

Good Luck!
