Introduction

First we would like to thank Crucial Europe for supplying us with this memory.

Crucial is a division of micron. They build their own Chips and PCB, not like all the other manufacturers who have the DDR-Ram only soldered together and referred their chips and PCBs by other manufacturers. On the Tracer PC4000 are also unique leds for a good look. Although Crucial/Micron is not normally known as overlocking ram we will do an extreme overclocking test with high voltages and try to find out if they are a good alternative to Ram with Samsung TCCDs or low latency like Winbond UTT BH-5/CH-5.

The chips are getting really hot, so beware for giving to much voltage! Around 3.0-3.1V looks fine for me.

Here you can download a small Video (5.1 MB) of the Tracers in action.

Here you can see the system we tested on.

Test System
CPU:	AMD Athlon64 3200+ (S939; 512KB; Winchester)
Motherboard:	DFI Lanparty nForce4 Ultra-D
Memory:	2 x 512MB Crucial Ballistix Tracer DDR PC4000
Video Card:	Connect3D X850XT@ 520/540MHz
Harddisk:	1 x Maxtor Diamond Max 10 160GB
Power Supply:	OCZ ADJ 420W
Software:	Windows XP Prof. , Catalyst 5.8

All parts are selected with high performance and good overclockability in mind to reach high test results. We used BIOS 704-2BT for the DFI Lanparty nForce4 SLI-D.
All AlphaTimings in the Bios are set to auto, except for:

• CPC - Enabled
• DRAM bank Interleaving - Enabled
• Idle Cycle Limit - 256
• Dynamic Counter - Disabled
• R/W Queue Bypass - 16x
• Bypass Max - 07x.
• TRAS always at 7, this gives highest memory bandwith when used with the Integrated Memory Controller (IMC) of the Athlon64.
