TechNet Posted October 29, 2005 Share Posted October 29, 2005 TWIN2X2048-6400 / XMS2-6400 / DDR2-800 / 6400 I have this kit in a Shuttle SD31P which uses the Intel i945G chipset. Other componetns include an Intel Pentium P660 (3.6Ghz) and a nVidia 7800GT. The results below have been tested at 5-5-5-12 with 1.9v upto 2.1V at an FSB of 200mhz and a multiplier of 3:5 meaning the memory is running at 667Mhz. The machine has passed a MEMCHECK 1.6 run over 24 hours without error. When I run SiSandra 2005 the Memory Bandwidth Benchmark I get the following results :- RAM Bandwidth Int Buff'd iSSE2 : 5317 MB/s (this is what I would expect to see) RAM Bandwidth Float Buff'd iSSE2 : 759 MB/s (this is about 1/8th of what it should be!!) Results Interpretation : Higher index values are better. Int Buff'd iSSE2 (Integer STREAM) Results Breakdown Assignment : 5218MB/s Scaling : 5196MB/s Addition : 5387MB/s Triad : 5467MB/s Data Item Size : 16 byte(s) Buffering Used : Yes Offset Displacement Used : Yes Bandwidth Efficiency : 75% (estimated) Float Buff'd iSSE2 (Float STREAM) Results Breakdown Assignment : 761MB/s Scaling : 764MB/s Addition : 760MB/s Triad : 754MB/s Data Item Size : 16 byte(s) Buffering Used : Yes Offset Displacement Used : Yes Bandwidth Efficiency : 11% (estimated) I then tried the memory benchmarks in Everest Home Edition and they were also about a 1/5th of what they should be. HELP!!!! The only other info. I can tell you is I originally had the TWIN2X1024-5400C4 kit in the same machine and I was getting benchmarks in the low 5000s for both tests as I would have expected. Do I have a faulty module(s)? Link to comment Share on other sites More sharing options...
