First Time OC'er - Help!

post #1 of 12
Thread Starter 
So I've read the big 3 guides on OC'ing but it hasn't quite sunk in yet, mainly because my mobo's settings mostly don't match the names listed, so it's confusing me a bit.

So far I've only been able inc my multipler/bclk. Above 143 bclk and windows didn't want to load. I've got my system info listed for reference.

Again my bios settings and what I should & shouldn't disable/enable/set manually is mainly what I'm confused on. Anyone have tips for the P6T board?

Also, I've noticed now that my multiplier is bouncing between 12x & 21x in CPU-Z after my attempt. What's going on?

Thanks!

The multiplier bouncing is intel speedstep.

How do you have 8GB on a 1366? Unmatched ram?

Slots B & C... triple channel RAM never worked for me, possible dead slot. It's not unmatched, it's the Corsair Vengance 8g dual channel kit.

Is SpeedStep something i can/should disable?

That sucks, RMA your board if that's the case. It might still be under warranty.

You can disable it in the BIOS - and whether or not is really a matter of preference. It won't hurt anything; it's just a power-saving mechanism that allows your operating system to throttle down your CPU when it's at low-usage. I always turn of intel's turbo function when OC'ing, though.

Id Recommend RMA aswell (if applicable), if your triple channel is dodgy, who says thats the only thing wrong with it.

Thread Starter 
The board is a year old now, highly doubt I'd be able to RMA it. Besides, the research I'd done a few months ago made it pretty clear this model had issues with triple channel ram. No issues with the dual channel stuff though.

My main difficulty is just trying to translate what settings are listed in the OC'ing guides to what my BIOS settings are showing (IE - SpeedStep is EITS). Most of the names used for the voltages are abreviated or called something differnt so it's been a learning experience so far.

I think once I have that figured out I can start trying to bump up my BCLK & see what I can squeeze out.

Stay tuned & thanks for the info so far.

Ok, I've disabled EITS & played a bit with my vcore/bclk & managed 3ghz. Running prime now for stability. Temps hanging ~53c on full load.

Thoughts? Mistakes? Countdown till I blowup my PC?

Thanks!

You can safely bump the CPU Voltage to 1.25v - 1.3v (but look out for the temps! And run Prime95 or LinX to test stability and load temperatures).

Also what is your CPU PPL and QPI/DRAM voltages set to? You can set the PLL to something around 1.75v or maybe 1.8v, and the QPI around 1.3v.

Lastly, do you run any form of divider for the memory? The option should be called DRAM Frequency, see if it helps keeping it close to the memorys stock speed of 1600MHz, you might be able to get a higher BCLK.

Ohh and be sure to keep your PCIE Freqency at 100MHz if you haven't done so already.

EDIT: I don't know if this still applies (been out of the game for a few years, and I'm just playing catch up again), but in the "olden days" disabling CPU Spread Spectrum increased stability when OC'ed. But you'd have to get a second opinion on that one

And here's where my confusion (and curiosity) begins. What exactly does raising & lowering the voltage do? What kind of increments should I use? What effects will it's value have?

These are all still set to auto.

Not to sure what you mean. I know my DRAM frequency is still set to it's default. When I tried to increase it, windows would fail to boot so I think I had the wrong values there. Some of the 930 OC guides mentioned it's value so I'll have to check it out.

Ya, everything I've read said to leave this alone or use it as a last result. I doubt I'll touch it.

I'm pretty sure I have these both disabled (there was a couple of options with spread spectrum) but I'll have to double check.

Thanks for the info!

Your CPU needs power to run at a specific frequency. So naturally when trying a higher clock you'd need more vcore (CPU voltage). Altho most CPU's today OC fine on standard voltages. They still need more juice to run the crazy speeds that we see around here.
As for increments, I usually go up 0.025v pr. bump if possible.

Try with the PLL voltage at 1.75v and the QPI Voltage at 1.25v (maybe bump this up to 1.3v)

Well, a divider is used to "divide" the clock of the FSB vs. the Memory Clock.
So when the bus speeds of the CPU's, started getting higher than what our memory could run. Dividers were used to get the memory speeds down, while keeping the CPU's bus speeds up - Effectivly dividing the ratio between them.
We don't use a FSB (Front Side Bus) today, but the concept of dividing the memory speed is still there.
Now you can basically set a BCLK and DRAM Frequency independendly from each other.
The option is just called DRAM Frequency, and to test the CPU OC'ing capability, you'd want to keep your Mem at their stock speeds. So set this option as close to 1600MHz as possible

Hehe great, thats also the way to go

Ahh ok, this probably also differs from board to board / Chipset to chipset.
But I've read up on it a bit today, and it does still give you some stability
