Page 2 - Max oc for 4800+

Okay, keep me posted. And try not to set your bus frequency higher than 245 unless you really have a good cpu heatsink

I'm running 2.95GHz stable, with the default multiplier, and all of voltages brought up a bit, the vcore is at about 1.44V!

WOW!! good overclocking there!! What cpu cooler are u using??

I can't seem to figure this out.

I'm using the stock fan, and I've been monitoring the temp. it hasn't exceeded 45, and it avarges at about 35C!

I give up, 2.5 GHz is my max and I refuse to believe otherwise.

Try to physically shoutdown the PC in between settings!

I have tried that with no luck.

Which mobo??

Gigabyte GA-K8N Pro-SLI (socket 939)

Ok, well if your ram is at 360mhz, is that what the fsb is at? Because in the bios your ram should be set to run at 180mhz in order to acheive an overall speed of 360mhz. So if you have your multiplier at 10x when default is 12x and you are still overclocking than your HTT is way to high and you are trying to get nearly a 100% overclock on your ram.

Think about it this way.

You have your bus speed (stock is 1000mhz)
then you have your HTT multiplier (stock is x5)
So your actual HTT speed is running at 200MHz
You then have your cpu multiplier (for you it is 12) so 12x200mhz = 2.4Ghz (stock clocks)
Then you have your ram (generally at stock its just x2 so 2x200MHz) 400MHz which is standard speed for pc3200.

Thats correct. my motherboard has a ram divider that can be changed (default is 2/2)

If I could printscreen what I see in the bios I would, tho idk if it would help

Well you say your ram is under clocked, and your cpu is underclocked, but you can't boot?

Why is your HT at x3 if you are just trying to overclock 100MHz?

Drop everything back to stock, and just increase the HTT from 200 to 209.

Try it, try to boot, run super pi 4m a few times.
If it fails, try each of these.

Take the HTT to 4x, and take your ram to the 9:10 divider, or 4:5 or whichever it has that is closest to it. If you can't get your chip to boot at a 100mhz overclock then some of your settings are way off.

So if it fails with just the HTT up, then drop the HTT multi back, boot to windows, run super pi 4m a few times, and if that fails continue to drop your ram back.

If you get one that works, just start checking those settings as you bump up the HTT 5mhz a few times, and once you start running into issues go up 1 or 2mhz. If you run into trouble and your ram is running under stock and your HTT multi is keeping the bus under 1000MHz then you probably will need more cpu volts, which you have to decide if you want to do that or not.

Remember, Change 1 setting at a time, and then check for stability. Once you get to a nice overclock run prime 95 (or orthos) overnight to check stability (make sure both cores are getting stressed which is where orthos will help out).

Here's what I see in the BIOS as far as overclocking:

HT Frequency Ratio default 5x
CPU Frequency default 200 MHz
K8 CPU Clock Ratio default x12
CPU/DDR Clock Ratio default 2/2 (400 MHz)
CPU Voltage default 1.35v

As I type this, this is what everything is set to now:

HT Frequency Ratio 4x
CPU Frequency 210 MHz
K8 CPU Clock Ratio default x12
CPU/DDR Clock Ratio 2/1.83 (384 MHz)
CPU Voltage default 1.35v

This brings me to 2.52 GHz, not tested for stability yet.
It seems that if I go past 210 I cannot boot.

EDIT: I just thought of this, should I increase my CPU voltage? I'm a little scared to so I haven't touched it yet

One More EDIT: I just found this in an review for a similar motherboard:

"We were able to create a stable environment at 2.52GHz, and 2.58GHz became stable after we bumped our core voltage up from 1.3V to 1.4V. We next tried to jump to 2.62GHz. We did get a stable environment here, cranking our CPU voltage to 1.65V and pushing the memory to 2.75V"

Looks very similar, tho I'm still scared to touch any voltage settings.

Just change you cpu volt to 1.5, then fsb frequency to 220. It will works. Or set your vlotage to auto if you don't dare to change the voltage setting. Because if you dont increase your voltage and you can't increase the performance as it needs more voltage to run faster ( does it make any sense??)
