Solution Update the BMC code to 1.11 or higher. The file will be available from the IBM System x Support web site. Additional information The BMC level 1.11 code increases the blower speed in the chassis providing proper cooling for 2 or 4 Gigabyte DIMMs. Overheating can cause Single and Double-Bit errors resulting in banks of DIMMs being disabled. The DIMMs should not be replaced when these errors are seen at lower BMC code levels.

If this is the memory issue, what kind of isuue? Thanks in advance! RE: IBM blade 8832 memory issue victorv (Vendor) 29 Jan 07 10:01 hi,- Type-Model : 8832-xxx ?- which were the slot occupied by the original memory ?- which the new ?or there was not memory ?Remove the newly added DIMMs and restore the original situation: the original DIMMs in the original slots.and see the log: does the server go ?byevittorio RE: IBM blade 8832 memory issue bmin (TechnicalUser) (OP) 29 Jan 07 11:11 Changed the new modules and got fixed. One more question: is this possible the module failed on the sleeping mode? As I tested those modules on a memory tester, it shows slef-refresh test failure.Thanks again!Bigang Min Red Flag This

In addition to memory type, speed, and timings, there are several other issues to consider in choosing proper memory for your system. memory error We'll examine each of those issues in the following sections. Dual-channel operation¶ For best performance, modern processors require a great deal of memory bandwidth more than can be provided by a single memory module. For example, an Intel Pentium 4 processor with an 800 MHz FSB can use memory bandwidth up to 6.4 dimm pair 0 GB/s, twice that provided by a single PC3200 DIMM. To accommodate this need for greater bandwidth, chipset engineers designed dual-channel memory controllers that recognize two physical memory modules as one logical memory module, effectively doubling the data transfer rate between the CPU and memory. WHEN DUAL-CHANNEL MEMORY MATTERS Enabling dual-channel memory operation requires that the motherboard have a dual-channel memory controller and that you install memory modules in matched pairs. Ideally, the two memory modules should be identical, but most dual-channel motherboards will accept any pair of DIMMs as long as they are of the same capacity, type, and speed. Most dual-channel memory controllers will operate properly in single-channel mode if you install only one DIMM, but system performance may be significantly degraded. Dual-channel operation may or may not be important to system performance, depending on the processor you use. For example, the fastest Athlon XP processors use a 400 MHz FSB. Because the Athlon XP use
