Well this is strange case, , but I get shocked when I install windows 7 x64 in notebook (acer 4540) with 4GB ram, 2,3 GB AMD Turion 520 Dual Core, 320 GB WDC SATA HDD, the performance are slow (for this I rate 3 becuz it really slow), even with tweaked setting, also optimized the startup, oh I almost forgot, pointer error, sometimes it jump suddenly even we didn't move it, with keyboard error too but I manage to turn off the num lock n it normal again. It totally different when I installed it in my desktop pc, well is it an old pc, the specs is 3 GB ram, 1,8 GHZ Intel Dual Core processor, Gigabyte GA-945P-DS3 mobo, with 160 GB Seagate SATA HDD, also updated from solor updated pack n the pc run smooth, with some tweaks from the registry in this forums it really nice (well I rate with 8). If we compare, the specs from the notebook n the pc we will know the notebook specs are higher, but what I really dont understand, why the performance are slow? Does anyone have this issue?
mmm interesting. Did you try with win 7 x86 ? Did it make any difference ? This way we can know if the problem is related to the x64 version and narrow down the possible causes of such problem.
No, it's not make any differences n I dont think it's related since 32 bit version only read max ram below 4 GB (actually it will detect 3,25 GB if we choose 32 bit). Yes I have n it's not becuz of that, anyway latest release bios of Acer Aspire 4540 is 19 Jan 2010 (v1.05) so I didn't outdated for this! Anyway, I wanna ask u guys, do u enable sata mode for example in Acer Aspire 4540 is AHCI mode/not IDE when installing Windows 7? I think it's becuz of that, I wanna test that but I might have to reinstall again,
only need to do that if you have an existing installation and want to convert to AHCI.... otherwise for a fresh install, turn AHCI on in the bios and then just install 7.... it will automagically load the right drivers
