I'm still kinda new to this fangled OC'ing thing. These are the current settings I have in my NF7-S BIOS. Could you guys look and tell me what settings I should change for best performance and more mhz?

System BIOS Cacheable = Disabled
CPU Disconnect = Disabled
CPU Interface = Enabled
Drop Chipset Voltage to 1.6
Then go back to the "Soft Menu III" and set the multiplier to 11 and the FSB to 200 and run it to see if it is stable. Do some torture on it. Then up the FSB in increments of 5. If it won't boot, doesn't load windows or windows becomes unstable increase the CPU Core Voltage to the next 10'th (ie 1.8, 1.9, 2.0) till it runs stable. When you get to a point where it won't run stable or it is too hot you will need to start backing down be increments of 1. You will need to keep a watchful eye on your temps as you do all this and the low 40's C is as far as you should go for an idle temp with full load arounf 50C or so. Raising the core vols will increase temps faster than anything else. I suspect you will end up with a final speed between 2.2 and 2.4.
As I recall you have an Alpha PAL8045 HS. Before changing anything put it to full load for 10 minutes and record your temps then flip the fan so it is blowing in the opposite direction and run full load again. Both runs need to be made with the case closed. I say this because each system is different and it will make a big difference in cooloing potential.
I'll try that out when I get home. I haven't tried stressing my system since I switched to 2-2-2-5 memory settings. If those are too low, will it mess with my stability? Should I switch them back to 2-3-3-6 until the OC'ing is done?
I switched the memory timings back to 2-3-3-6, because I think that was affecting stability but I can't get it to run stable past 192x11/1.7v.
I tried 200x11 and even up'ed the volts as high as 1.85v, but couldn't get it to run Prime95 without an error. Temp was never an issue as it never went past the mid 40's. What else can I try?

I know you have a new high quality PSU but what are your voltages?
Try upping DDR volt to 2.8
Set mem timings to optimal.
If that doesn't work, try removing 1 stick of memory.
I changed the pictures in the top post to reflect my current settings. Unfortunately, I can't try bumping up the memory volts until I get back home tonight. This is bugging me because my memory should be good until at the very least to 400mhz, right?
Also, will OC'ing the the FSB affect my PCI slots? Right now I don't have anything in them, but my video capture card will be in there eventually.
The NF2-s locks the PCI and AGP bus speeds (thankfully ). Today's boards ONLY overclock the memory for added bandwidth.
Download memtest to stress just the memory (keep the cpu at default to eliminate that as a possible cause for instability). Memtest runs from a floppy upon rebooting the PC, so copy these files down to a floppy and make sure to have the first boot device in the bios set to floppy.
Once the memory's peak is found at the minimum timings you'd want, then you can see how high you can get the clock on that cpu.
Originally posted by Stalker is there anyway to run memtest without using a floppy? i dont have one in my computer right now
I imagine a bootable CD would work as well, but I think the download only extracts to a floppy by default (??).
There are other programs, like hotcpu, that offer memory burnin stress testing, but it's not as effective as having nothing loaded into ram other than the data assigned by the testing software.
