Memory Question ?
Hi all,
I have the following memory sticks currently in my computer Corsair 2GB DDRF2 800MHz/PC2 6400 XMS2 NON ESS Ubuffered CL5 I also have 2 empty slots. The question is - Can I populate these two with the same brand of Memory sticks but slightly faster like 4-4-4-12. If I do, do I need to fiddle the BIOS setting or what. Thanks for your help. |

Memory Question ?
Hi all
I forgot to mention that I am using Abit IP35 Pro mother board and that the memory pair currently installed works on 1.9 volts and the one I like to install works on 2.1 volts. |

The bios should pick up on the CAS settings and automatically set that for you. As for the voltage, you might have to find a happy medium or try running the new memory at a lower voltage. I would think that your old and new memory should work ok at 2.0v. 1.9v as a max voltage sounds a bit conservative to me. On the other hand, if you are not overclocking the memory the new memory might run just fine at 1.9v. Ed |

Your system probably requires unbuffered memory. Your initial two 1 GByte sticks should be inserted into two slots that allow dual channel operation, so the two empty slots should be the two used to install your two new sticks. It's just my guess, but I'd say you will not need to make any changes in the BIOS. Any memory module can certainly run at speeds and timings LOWER than its stock ratings. The only potential problem I see is the higher voltage for the second pair you mention in your second post. I think I'd split the difference and run BOTH pairs at 2.0 volts, while running the new pair at the slightly slower timings of the older pair. As a trial I suggest you replace the older pair with the newer pair and check performance; also check it the BIOS has automatically raised the memory voltage to meet the parameters stored in the SPD on the modules. Then try the new modules with the timings set the same as the older memory, then check performance with the slower timings and the voltage set at 2.0 volts and 1.9 volts to match the older modules. It would be better to have modules that require the same operating voltage, as I don't think different module slots can be supplied different voltages. But you should have no problem operating the new modules at timings relaxed to match the timings of the old modules ad the operating voltage dropped by 0.1 volt (and raising the older module operating voltage by 0.1 volt.) Or, as a last resort, running both pairs of modules at 2.1 volts. Of course it would be best to have all four modules have the same stock operating voltage. Finally, it may be, if you were to read out the SPD contents, that BOTH pairs of modules have the same stock operating voltage when operated at the same memory timings B^) Phil Weldon wrote in message ...
