I have just install 4GB RAM (upg form 2 GB) and my vista ultimate x64 stops booting
When I remove 2 modules it boots again strange. I thought that the new modules are bad, but it doesn't matter which modules I use - when it is only 2 modules in : vista boots, when they are 3 ore 4 it doesn't ;
There comes interesting part: when I try to reinstall vista, booting from DVD, the error message comes:
your system is not fully ACPI complaint
...but if I remove 2 modules of ram, suddenly it becomes ACPI compliant and vista setup is proceeding normally;
I have searched around for this problem: some say that I have to disable ACPI function in BIOS to resolve this issue, the problem is that when I disable this in BIOS the PC did not POST ( I can disable ACPI in BIOS if there are only 2 modules of RAM). Although I am sure that this is not memmory problem I run memmory test and there were no errors;
Since it is not memmory failure I think that the problem is something else.
Anyone with similar problem, please help ?
I'll appreciate any ideas that might solve this issue.
thanks in advance!
mobo: MSI K9A2-CF-F (790X chipset)
RAM: 4 X GEIL DDR2 800Mhz (4-4-4-12) 1.9v non ECC, unbuffered
@ pat: doesn't work with 2.0 v Is there any risk if I try with 2.1v ?
@ djbrad007 : sory mate, I'm a noob in this slipstream thing can you explain me how can I do that. meanwhile I'll try to install the fix with 2 modules and then to boot with all of them. Really hope this works
@badge: BIOS updated to last ver. No point reinstall drivers since I cant boot form vista dvd. NB volt. increased form 1.1 to 1.3; RAM volt. increased from 1.9 to 2.2 (that is max supported), frequency set to 533 Mhz - still not working
I have dualboot so I can boot XPx64 and there is no problems at all memmory works fine even at 893 Mhz 4-4-4-12 2.0volt
...as soon as I remove randomly chosen 2 modules of RAM - vista boots and operates fine. When I reinstall all 4 modules : on booting vista shows a blue screen and restarts emediately (even cant see what is the message) AND when I boot from Vista DVD it says: "your BIOS is not fully ACPI compliant" and freezes I've tryed with vista x86 and the same thing happens. Even though XP (32bit & 64bit) works fine!
...sounds like vista problem ?! what you think?
P.S. after BIOS update I have no longer able to select DRAM clocks to 4-4-4-12 The smallest values I can choose is 4-5-5-15 WTF is wrong ?!
