Help overclocking on my KR7A

**Ritalin Kid** · April 1st, 2002, 01:50 PM

Ok guys got some new setting here I'm not to familiar with like this FSB/AGP/PCI setting thingy... looks like 4/2/1 and you can change it to 3/2/1 but when I do it doesn't like it.. and my only safe OC is using 140 FSB at 4/2/1... are there any webpages out there that tell you how to get the best results out of your KR7A when you want to overclock it?

anybody?

Well it depends on the processor, ram, etc. so I doubt anyone has your exact setup

gotta 1900+ 1024megs of Crucial DDR PC2100 (non ECC).. 2 60 gig maxtor on RAID0..

KR7A is the supposed BEST OC board for XP at the moment, not alot of hard core OC'ers here, check out OCAU--you can get alot from these guys since more of them are aggressivly using it: http://forums.overclockers.com.au/sh...highlight=KR7A

Well it seems if I barely oc it to 140 FSB I get an error message at start up about some files being missing in the SYSTEM32/Config folder and I have to reinstall windows...

I'm using a Volcano 7 and it gets around 47C at Load with default settings.. (1900+).. If I OC I guess it either eventually overheats and corrupts data or won't reboot at all, I have to clear the CMOS and start over again...

I'm thinking that I need to reapply my AS2 I might have put it on a little thick and the Volcano 7 has a thermal sensor that speeds up the fan based on the temp of the system not the CPU and I have tons of fans in my case so I think the sensor is not getting hot enough to speed the fan to 5000RPM when it needs to..

It's at 42C right now and steady according to the hardware monitor.. haven't had a chance to check it with my LCD Temp sensor yet..

Keep it 4/2/1 if your 133Mhz or over.
3/2/1 is made for 100Mhz operation.

This setting has nothing to do with RAM speeds.

The only BIOS settings that will heavily effect overclocking are RAM speed and voltage. There are others that will as well, but they arent as drastic as these two.

Set your RAM's latency to CAS3 to push the CPU the farthest. CAS2 performs better, but CAS3 allows the RAM to run more Mhz, alleviating one bottleneck, sine the RAM runs the speed of the FSB. I dont think the "turbo" settings will help much with anything in OCing, so I would leave those on turbo. Note that your RAM may work at CAS2 at high speeds, but you should keep it on CAS3 when clocking just to put down that bottleneck for the time being. Once you max out the CPU, you can kick it up to CAS2 and see if its still stable. If not, you either need to downclock or leave it at CAS3.

And voltage..this ones dangerous. Move voltage makes the CPU put out more heat, but tends to make the CPU stabler. Its a delicate balance between heat and voltage though. Too much voltage and the added heat will worsen the stability. Too little voltage and you may not be able to clock it to your desired speed.

Voltage is a huge factor in making CPU's stable at high speeds though, so its something you definitly want to clock if your going for high speeds.

Keeping it under 50 is safe. Dont worry about anything when testing til you hit about 55. Recommended system temps under normal operation (for me) is under 50, but when you need to max out a overclock, I lax my recommendation somewhat, and then compromise after i find out my max OC (either by clocking it down, or gettin me a more powerful HSF

)
