Only 790 MB free Ram in Win7 SP1 on z690 board

[Dietmar]

Hi,

I just test win7 SP1, win8.1 on the Gigabyte z690 UD DDR4 board, both bit32 versions.

In win7 SP1 I have to change the acpi.sys against my modded version, because it shows Acpi A5 BSOD during install.

The for XP modded USB3 driver works there.

But compi is slow. A check shows, that only 790 MB ram are free, the same for win8.1.

Any idea, for to get more ram

Dietmar , try this.

How to enable memory remapping in BIOS.

From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > Memory Options > Memory Remap.

Select a setting. Remap All Memory—Makes all memory in the system available again on the next boot. No Action—Leaves any affected memory unavailable to the system.

Save your setting.

Hi Dietmar, I have the same mobo z690 UD DDR4 and I wish to run win 7 x64, but unfortunettly i can't get rid off BSOD 0xA5 (0x11, 0x08). Can you share me your modded acpi.sys?

I would be very grateful for help

EDIT:

When I use your acpi file from that link: https://ufile.io/c2bc9ntv I'm getting the 0x7E(c0000005, ...) error. In attachment I uploaded my oryginal acpi.

Regards

acpi.sys

Here is first try. For win7 bit64 I have never done this hack before,

so may be, that you get endless loop

@Dietmar Thank you very much! Works like a charm!

For anyone attempting to install Win7 x64 on Gigabyte Z690 DDR4: look for the driver package named "SHA256_Signed_modified_intel_IO_USB3.1_driver_32_64bit" - USB will work fine!

@kubadmck can you please explain where i should put this driver package into the iso? sorry for this late reply.

[jacer4]

sorry i misunderstood. ignore my above reply.

@Dietmar can i ask that you please update this link https://ufile.io/mtx2ub7j which contains "acpioriwin7bit64DDB11h8hack.sys", because it now seems to be paid access only

i share the same motherboard and i have been trying to get windows 7 to work for 3 days now. i would be very grateful if you could send another link for your modded acpi.sys file. thank you!
