p4 2,4 800 & Sapphire 9800 NP

[Totto]

Hello!
I've just bought a P4 2,4 Ghz(800 Mhz) and a MSI 875P NEO-FISR2 mobo with 2x256 TwinMos PC3200 (matched) and a Sapphire 9800 non-pro. My question is if I can overclock the CPU to say 2,6 or 2,8 without getting extra cooling and such and how to do it, also, can I increase the speed of the 9800 a little without flashing the bios? If so, how much (again, without additional cooling)? Should I use a tweak program for this or how do I do it the easiest way?

You can get to at least 3.0 without additional cooling, the only thing that would hold you back is your crappy memory. First set the Dram ratio to 5:4, now overclock the FSB to 250mhz. That would get you a 3.0G with DRAM frequency at 200mhz. For the 9800 non-pro use the <A HREF="http://www.driverheaven.net/downloads/index4.htm" target="_new">Omega Drivers</A>.

crappy memory? I thought it was quite good? Anyway, so if I would want to go to say, 2,6 or 2,8 How do I do that?

My guess 225 Fsb should get you 2.8. But you have to play with your Bios. Go for 3.0 Ghz that's what I did with my 2.4C.

Anything lower than PC3700 to me is crappy.

My PC3500 HyperX works fine for me.

 

[scottchen]

Well the thing is you can't use syncronized FSB.

You can overclock to 3GHz at 250MHz bus using the 5:4 memory ratio (usually enabled by setting memory type to DDR333 base speed, which overclocks back up to 200MHz, aka DDR400 speed, when the CPU bus speed is increased to 250).

Okay, thanks all So, following Crashmans advice (which I hope will work despite my crappy memory), I won't need any extra cooling than the boxed CPU-fan and no extra cooling for anything else? Also, there is no need to increase voltage to anything or? And all this can be done safely without my computer going down the drain?

 

[Crashman]

Stock cooling should work, but you might need just a little more voltage to stabilize things.

coolness, and the voltage is also adjusted in the bios? how much should it be set to then?

 

[Crashman]

Max I'd go with the CPU would be 1.70v, but you'll probably get there with 1.65v or less. Lower is better as long as it's stable, because it reduces heat and power consumption.

You might need to add a little more voltage to the RAM to make it stable as well, max I'd go would be 2.8v, but lower is again better as long as it's stable.

I'd try them both at stock voltage first and make the smallest changes needed for stability. Both settings are in BIOS.

If you do everything that the poster here have told you, and it still keeps crashing, its because you have got the AGP/PCI bus speeds lock to the FSB. AGP and PCI sockets don' like to to overclocked so keep them at a default setting of 66/33.

I had to say that, as when I tried to Overclock my 2.4C chip I couldn't get it passed 2.5Ghz, and it was the AGp/PCI bus that was stopping it.
