Refresh Rates, What Is That????

Recommended Posts

I'm back for more torture. Built my gaming computer and here's the specifications:


AMD 64 3700+

Corsair TwinX 512MB CMX512 3200C2PT XMS3202V5.1 (slots 1 and 2 for 1GB)

Spread Spectrum Disabled

AGP Aperture Size 256M

AGP Fast Write Auto

CPU Thermal-Throttling Disabled

HT Frequency 5x

Max Memclock 200MHz

Current Memclock 200MHz

DDR Timing Manual

Cas# Latency 2.0

tRC 7

tRFC 9

tRCD 5

tRRD 2

tRAS 5

tRP 3

tWR 2

tWTR 2

tRWT 4

tREF 2x2592 (What is this and what is the best setting? I have tons of choices. Anywhere from 1x1551 to 4x4672 then the last one is 128 cycles)

2T Timming Auto (Disabled and Enabled gave worse 3D scores)




CPU Voltage Normal

VDDQ Voltage Normal

VCC12_HT Voltage Normal

DDR Voltage +0.2Volts


Anything lower on these settings, except tREF because I haven't touched that setting, causes a parity error and reset. I wrote down 3DMark scores as I decreased these setting and it go better every time. The only time it got worse, and by a lot, is when I switched the ram to slots 1 and 3.


I really just want to know if the HT Frequency and CAS# Latency are okay or if I can get better performance by lowering the HT and increasing the CAS#. Also I would like to know what to set the tREF to? Thanks.
