I was wondering when abouts you guys could no longer use default voltage during your overclock. Right now, when I set to 200fsb, I have to up the voltage from 1.5V to 1.60V while lowering the multiplier to 10.5. Should I also max out the Northbridge voltage? I have no clue when to judge when the NB needs more voltage. Also, for this board and processor, is it feasible to obtain FSB 216, Multiplier x11 with CPU voltage not exceeding 1.75V? I know every chip is different, but I just want to see what people have been able to do with air cooling.

In addition, after I make a change to my FSB and Multiplier, and voltages, I usually cannot boot. I get no signal to my monitor, and only after turning off my power supply for 15 seconds - I try to boot and the BIOS tells me "CPU is unworkable, or an unappropriate change has been made." I dont really use "out of the world" voltage and FSB/multiplier settings, so Im not sure if this means I have a damaged cpu or something. After the latest bout, I changed the multiplier down from 11.5 to 10.5 and raised the voltage to 1.6V and maxed out the NB @ 1.7V with FSB at 200 ~ so far no problems. Is this were my overclocking ends? or is there hope for more overclocking?

My ram is Mushkin PC3500 Level 2 (2x 512MB)
My HS is the Coolermaster Aero 7+

Thanks in advanced!

Only add more voltage when your OC becomes unstable. Add increments of 0.5v till it becomes stable again. Repeat until max overclock reached. You shouldn't need to add more power to the NB up to 220Mhz FSB, only the RAM.:beer:

EDIT - You might want to invest in a better heatsink such as an SLK800/SLK900 with decent fan.

Hmm, thanks! Im working on getting either an SLK 900A or SK 97 But not sure which one i should invest in. Ill take my NB voltage down back to default. When you say "OC becomes unstable" what are you referring to? Are you referring to "booting windows" or actually running something like SuperPI 8M digits and FFXI Bench simultaneously.

thx

Pretty obvious really. When your computer becomes unstable. A computer that crashes as a result of an OC no matter what the situation/application is an unstable computer. Stable is something that doesn't crash.

I just got an abit nf7-s and slk947u to accompany my 1800+ dlt3c last week too.

While I was looking around for tips, i stumbled upon this site. It might be of use.

As far as I know, the only reason to get a 947u, instead of a 900a is if you might be considering going with a P4 in the near future, because it will fit both. The 900a is the one that actually has the Athlon heat sink clips. To use the 947u, you must remove the motherboard, not my idea of an "easy install", compared to using the clips. Here's a link to a good place to buy both: link to newegg's Thermalright page.

Thanks, I was leaning towards the 900A, but read somewhere that you should remove the HS everytime you travel with your box. I dont really want to deal with that... Is there really that much risk that the 900A or similar would rip off the ZIF socket? Say when I travelled, i were to keep the Case on styrofoam and on the mobo side down, would that be good enough, or would there still be a risk that the HS would cause damage...
