dram clock question


Recommended Posts

i have some question abt this dram clock....pls help

1. what is actually Host clk and PCICLK?

2. my pentium 3 933 is set up by ( 133 x 7 )..if i wanna oc it to 143 x 7=1001, what dram clock should i set? ( PCICLK OR HOST CLK)

3. i know that pci clock runs at 33mhz, but what is the maximum frequency for the pci devices can stand?

thanks

I wont go into a detailed explanation of what host clock and pci clock are; I'll simply say they have to do with "timing," primarily how fast/often data is transfered in a cycle (or "tick").

As for altering your front side bus speed (133) to 143, your memory clock *typically* is the same as your front side bus clock (so you would set your DRAM frequency to 143Mhz). Note that unless you're using quality memory, there's a healthy chance that you will experience memory corruption (especially when under load), which can lead to other forms of bad mojo (such as disk corruption).

As for altering your PCI bus speed; I have one recommendation: DON'T. You're not going to see an outstanding performance gain from overclocking your PCI bus, mainly because there's no need to (unless you have a couple of gigabit ethernet adapters in your machine that run at full load 24/7). As far as I know, the AGP bus runs at the same speed as the PCI bus (correct me if I'm wrong here), so you might be able to inkle some performance gains out of it (wether it is enough for you to notice is another story entirerly).

Individial PCI devices will take adjustments to the PCI bus on a "per card" basis, that is to say, your sound card might not work, but your ethernet card might be just fine. From what I've heard, overclocking the PCI bus usually leads to distorted sound, video corruption, network instability, and, if you have an addon RAID/IDE controller card, data corruption. All in all, the risks of overclocking your PCI bus far outweigh the benefits (which are laughable at best).

Really, if you want more performance, get a new system.

i still dun understand the HOSTCLK and PCICKL. because once i oc the fsb, the pci frequency will raise up as well. so can i get any advantage from these 2 option? i mean just oc the fsb but this will not raise up my pci frquency.

.......for your info, i did not intend to oc the pci devices but i would like to know the maximum frequency it can stand.

anyway thanks to ur info;)
