Think ram is bottlenecking my system, how to overclock it?

I've been experimenting with overclocking to get some more performance out of my old dog of a pc.

i've come unstuck with oc the cpu as I think ram is causing a problem.

Here is my spec:


Motherboard asus A7v600 (fsb 400, ddr 400)

Amd athlon xp 2600+ barton 1.9ghz 333 fsb themaltake heatsink

768mg ram pc2700 333fsb



I've tried to overclock the cpu by raising the cpu fsb from 166-180

If I go any higher the system is unstable no matter how much I raise the cpu vcore. I get stable temps raising the fsb and vcore a bit, but the system is unstable.

I think my problem is that my ram is holding the system back and in order to get my system stable I need to overclock it to match the cpu fsb.

I have looked on the net to try and get my head around ram overclocking but cant work it out

If anyone can help me out it would be appreciated



Here is what I see in the bios:

FREQUENCY/VOLTAGE CONTROL

Cpu fsb clock (raised from 166 to 180)

cpu ratio: auto

cpu vcore: auto (can raise this and get stable temps, but system is unstable)

ddr voltage: auto

ADVANCED SETTINGS

dram host clock: 180 (dont think I can change this)

Configure sdram timings by (changed from spd to user)

sdram frequency: auto (can step up from 333 to 400)

sdram cas latency: auto

dow precharge time: auto

ras pulse width: auto

ras to cas delay: auto

write recovery cycle: auto

bank interleave: auto



Any ideas of how to get my ram going a bit faster to match the cpu?

find some ddr400?? or pump some volts

Okay marci he wants help not some dumb asnwer. Go into your bios, and go to ram overclocking, and you will see ram mhz, make it higher. And go into your voltages in the bios, and go to the ram voltages, and put it to like 1.9, or higher, if u overclock more.

antec.. it wasn't a dumb answer, it's my best recommendation. his current fsb is ALREADY giving that ram a significant overclock, I don't think it can be pushed further his 180fsb means he's already running the ram beyond spec

ddr400 would STILL be in spec, and allow him to push the whole system further

without knowing the manufacturer and model # there's no way to know if it'll survive more voltage


thank you
