Overclocking IC7-G w 3.0 P4 and Kingston PC3500 memory

[Kenton Flaig]

I've had this combo up and running for a couple of weeks.

Kingston suggested Cas Latency: 2, Ras Precharge: 3, Ras to Cas Delay: 3, Ras Active to Precharge: 7 with voltage increased up to 2.75v as a place to start for overclocking. Anyone have personally experience overclocking this combination?

Haven't used Kingston. But even at its default setting of 216 mhz, you'll get 3.24g or so. Relaxing the CAS to 2.5 might get you considerably higher, but watch temps, especially if you are using the stock hsf.

I'm clearly a novice at this. How do I tell what speed my processor is running at after it boots up into Windows XP?

look at the POST screens and you will see the values going up for both the CPU and the ram. remember that the multiplier is fixed in an Intel CPU so the only thing you can raise to increase bus speeds is the FSB.

most folks report that onboard devices such as the NIC and sound and other PCI bus stuff as well as the SATA controller start to go away if you don't lock the PCI bus at 33 and AGP at 66. you can try letting the PCI/AGP float up with the FSB but don't be surprised if they go away on you. If they do, just lock the PCI/AGP busses.

The easiest way is just to look at the "General" tab of system properties, you'll see a reasonably core speed in there.

The best way is to use a utility like WCPUID (www.h-oda.com). Even without that, you'll get within 20MHz or so simply by multiplying whatever bus speed you select by the P4 3.0's 15x multiplier.

Ya, I can't boot if the PCI/AGP thing is at anything other than "fixed".

BTW, what are the "POST screens"? I'm at the state of my learning curve where most of what I read here is Greek.

I've been able to get it to run at 235/3.525HGz. Should I be expecting more?

Temps so far have stayed below 55. I have a ThermalTake Xaser case and Vantec Aeroflow HSF.

POST stands for Power On Self Test and are the initial text mode screens that you see right at power on. usually the video bios is first then the mainboard starts to show information regarding the cpu and ram and what bios is installed and then installed devices among other information.

Lock the PCI/AGP bus. If you want to make your system unstable go ahead and overclock the PCI. Those devices can only clock up to 37Hz from 33. You are not really going to reap much speed. Run 1:1 ratio and try it at 216Mhz will give ya 3240. The cpu probably can go higher maybe 3.4 on air. Use the 5:4 setting if you want to see how high your cpu can go, that will keep the ram running slower for higher overclocks. I think 1:1 is best unless you have crap ram.

Myself I went with a 2.6c and run it at 250mhz fsb 1:1 which gives me a 3250Mhz with a 1000Mhz fsb (quad pumped 250).

It was cheaper to get the PC 4000 ram vs getting a real 3.2 chip.
