Overclocking older rig need some help...

[StealthMode]

Having a small problem I need some help with. Forgive me in advance I couldn't find image linking/embedding in the tools.

This is my stock settings/output.

This is my fsb freq at 150mhz (600mhz fsb). The core voltage seems to be dipping quite bad. But its stable.

The problem. My fsb:ram ratio is downclocking my memory when I increase the fsb this way.

I want to increase the fsb and oc the ram as well, but it seems if I touch the fsb at all it will just downclock the ram with the ratio. Temps are stable, got plenty of cooling.

When I attempt to force the ratio to 4:4 or try 4:3 @ 170-175mhz I lose sync with my agp port (no display to monitor). I did a search before posting and found this thread.

What I am trying to figure out is either a) how to get the ratio to stay at 4:4 at 150mhz with the agp/gfx remaining stable, or b) how to get the agp port/gfx card to remain stable at 170-175mhz @ 4:3 ratio without sacrificing agp/gfx performance (I want to oc the agp port too).

Any ideas/suggestions are greatly appreciated.

Kinda hard to guess since you didn't tell us what motherboard you have..

you DON"T want to overclock the AGP port, it doesn't do any good, it will do a good job of making things unstable though. You video card can't use the full bandwidth of the AGP port at stock speeds, so overclocking it literaly does nothing benificial. If your motherboard doesnt' have AGP/PCI locks, that is going to limit your OC, and there is no way around it. And from what I remember RDRAM doesn't overclock well either, so I would let it downclock.

Sorry bout the missing board info...

It's an ASUS p4t533 motherboard the only thing that can't be changed is the multiplier for the cpu. FSB, AGP, RAM freqs/ratio can be changed.

The gfx card is already 10% oc'd from the factory (bfgtech asylum gef fx 5200 core at 280mhz).

Yeah, I kinda figured it was that motherboard. It's the only one I know of that supports 32bit RDRAM. In any case, you don't want ot change your AGP frequency. That will make your system unstable, and give no benifit, overclocking the AGP has nothing to do with overclocking the video card. I don't think there is anything you can do to keep your memory ratio from changing automaticly, and when I used RDRAM it didn't overclock much at all, so better off to leave it that way.

Guess it's time to buy a p4 2.8 @ 533 I guess.

I was hoping to oc the rdram because I can't find this type of ram anywhere for sale and with only a 256 stick its kind of bottlenecking at the ram atm.

I guess its time to buy a new cpu or to bite the bullet and drop down to 800mhz ram.
