This memory is either incompatible with your board or you received a bad DIMM. What is likely happening is that, as more and more of Windows loads and starts executing, you reach a point where it uses a portion of memory that is not working properly (either because of the incompatibility of simple because this portion is bad). I would suggest that you download a copy of MemTest86+ and run it on your system for a full set of cycles. MemTest86+ installs to a USB key and you boot from this key to run it.
Hope this helps,
thank for the fast help
i try the memory stick on different PC, its working great, windows load and everything all good
...Then the issue is an incompatibility with the HC board. There are many things that can cause this incompatibility; here are a few:
- The board cannot handle DIMMs that use a x16 organization; only x8 organization is supported (the density of the DRAM ICs on the DIMM is beyond the board's capability to handle).
- The board cannot handle low-profile DIMMs (though this is usually because they also don't meet #1).
- The board often cannot handle DIMMs that require voltages other than 1.5V. By specification, all DIMMs are required to operate at 1.5V at default (1066/1333) speeds. There are lots of DIMMs around that cannot do so, however. Sometimes this is the result of their requirements for operation in their overclocking (XMP) profile(s), but this is still an issue and not an acceptable excuse.
- The board sometimes cannot handle the speeds requested by XMP profiles. To see of this is the case, place the memory configuration in manual mode and lock it to 1333 operation and see if this fixes the problem (if it does, then just leave it at this setting. Frankly, the amount of memory makes more difference to performance than the memory speed ever will).
Hope this helps,
