My RAM

post #1 of 6
Thread Starter 
Well I was poking around the options as I was overclocking (w00t – PC is slowly getting quicker!), and I thought that I might tweak the RAM (which, btw, is some “ValueRam†from Kingston (although the real manufacturers differ – Nanya and Xerox) I have two 512 Mb sticks, DDR400), as at first they were set to DDR333, and I changed the voltage from “auto†to 2.8 V, but apart from that I left all the settings at default, should I change anything? Here are the “specs†CPU-Z is telling me about them:
Frequency – 200 MHz (DDR400, so the actual Frequency would be 200, right?)
CAS# Latency – 3
RAS# To CAS# - 4
RAS# Precharge – 3
Tras – 8

I was also wondering if I should change the frequency from 400 to 433 (smallest change I can make), would this overclock the RAM or would it just screw it up?

It depends if it can take those timings at a higher speed.

RAM OCs along with the CPU, so you want to utilize a slower setting so that it has the room to increase speed. You don't want to OC the RAM, you want to underclock it.
Depending on how high you OC the CPU, the RAM should be set to either DDR33 or DDR266 speed so that it can move up in speed along with the CPU with out erroring.
Check your RAM speeds with CPU-Z as you OC to determine where it actually is running comparitive to the CPU's OC.
Also, keep the RAM's HT multiplyer in check. Default is 5x200=1000 so if the COU is running up to as high as 260MHz drop to a 4x, above 260 use 3x. Some BIOS refer to it as 1000 for 5x, 800 for 4x and 600 for 3x.

The guy has a Socket A processor, so he doesn't have to worry about all that HT multiplier stuff.

ok - using Everest 3, i tried a memory test (without closing firefox or XMPlay, so it isn't "exact") i got:
Mem:
Read - 5,713 MB/s
Write - 3,729 MB/s
Copy - 4,465 MB/s
Latency - 52.6 ns (top of the table - woo!)

ATM i have "DDR398" because i have put the ram to 333 (because this mobo has no divider, you have to do it through the speed of the ram), then overclocked it back up

oh, and is 2471 good in the "CPU Queen" test?
