I ordered some Kingston HyperX DDR2 PC5300 2x 2GB notebook RAM for my Compaq Presario C762NR and I'm running Vista Home Premium x64.
The problem is that when I took out the standard Hyundai sticks which were 2x 512MB and installed the HyperX sticks, the computer started, but the BIOS boot window didn't show, just a black screen. I rebooted it the 2nd time and the computer booted until the "Aurora" bootscreen (I disabled the scroll bar) and white dots show on left side and then on far bottem half of the same screen it scrolls down into blocks of pixalated colors. It then continues to boot to sign in screen where only a section of a square covering the blue arrow scrolls into pixalated colors. Signing in then takes me into bars of black and some weird colors with some of desktop showing, it then loads normally for about 1 minute before it freezes and I get a BSOD.
I take out one 2GB stick and it works flawlessly...
I even tried to (as quick as I could before Vista froze) get into msconfig and set maximum memory on bootup to 3072MB and restart, which I did but to no avail.
I downloaded a program called Vista Boot Pro 3.3 and changed the BCD Registry to reduce physical memory by 128MB so instead of 4096MB it'll show 3900MB. Finally it worked, but the problem was that Vista showed 4GB but was only using 895MB and only 211MB free with avg of 77% memory usage and my Video Memory (Intel X3100) went from 255MB/128MB Free/Shared to 128MB/64MB Free/Shared while still using AERO with no problem, but computer felt laggy.
I'm using SP1 so the KB929777 fix is already implemented but I have read that reinstalling the patch will fix the problem which unfortunately only works on Vista RTM, and if I do a RTM install without SP1, Vista refuses to download and install SP1 for whatever weird reasons so I'm forced to slipstream it.
I am in process of reinstalling Vista because the BCD program wouldn't let me start up anymore. I really wish someone knew how to take advantage of 4GB in Vista x64.
my Specs are:
Intel Express 965 Mobile Chipset
Intel Pentium Dual-Core T2370 (EM64T)
Hewlett-Packard 30D9 (motherboard)
BIOS: F.34, supposedly F.32 fixed the 3GB/4GB issue for 32/64 bits.
Sorry for long post, trying to be as clear as possible for best help.
