TwinMOS Twister PC3200 BH-5

Testing, Value & Conclusion »

Introduction

First we would like to thank TwinMOS Germany für supplying us with the tested memory.

TwinMOS is returning Winbond BH-5 to the Market with the Twister BH-5. This memory excels by having low latencies of 2-2-2-5 and an acceptable price. Like all memory in the Twister Series, the modules are designed to meet the requirements of power hungry customers. The orange Heatspreaders and the Twister writing are common for all sticks in this series.

Winbond UTT BH-5

Everbody who knows a bit about memory should know about Winbond BH-5. Those chips were designed for low latencies, and with enough Voltage they can run them stable at 250 MHz or even more. According to Winbond, the old BH-5 were specified for up to 3.6V, which means that, in theory, the new chips should not be harmed by this Voltage either. UTT means UnTesTed; BH the manufacturing process (0.175µm); 5 for 5 ns (1000/5ns = 200 MHz).
After a long break Winbond is finally producing memory chips again. TwinMOS relabels the chips, like all other competitors as well, because they are sold only as Blank Chips (no writings on them).

Here you can see the system we tested on.

Test System
CPU:AMD Athlon64 3200+ (S939; 512KB; Winchester)
Motherboard:DFI Lanparty nForce4 SLI-D
Memory:TwinMOS Twister PC3200 BH-5
Video Card:2x Pine XFX 6800 GT SLI @ 450/1200
Harddisk:2x 74GB WD Raptor RAID 0
Power Supply:OCZ ADJ 520W
Software:Windows XP SP2, Forceware 76.44


All parts are selected with high performance and good overclockability in mind to reach high test results. We used BIOS 310p 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.
