MSI 975X PLATINUM MOTHER BOARD AND WINDOWS 7 64-BIT
« on: 22-December-10, 14:00:04 »

My wife's PC was built in Akihabara at a store called Gtunes.

MSI 975X Platinum motherboard
Pheonix award bios V6.00PG
Intel 2.39Ghz Core 2 6600@2.4Ghz
2GB DDR2 557Mhz RAM

Installed a brand new Hitachi 7200RPM 1TB SATA HDD prior to install of OS.

When I tried to use 4x2GB of Elixr 1.8V DDR2 800 windows 7 Ultimate 64-bit would not install updates properly.  It kept getting errors during the installation of 13 critical updates.  I was advised to just use the original 2GB of DDR2 557Mhz RAM and unplug all devices except for a PS2 keyboard.  I did this and managed to install and properly update the OS to Windows 7 ultimate 64-bit.

It has been running stable for 5 days now with just 2GB of RAM.

So, now I've got 8GB of DDR2 800Mhz RAM sitting here and am wondering if I can safely install it in the motherboard without having some huge unrecoverable error occur.  When I put it in the PC during the update of OS I got some serious errors including a lost boot sector manager which forced me to start from scratch.  I really don't want to go through all that again.

I know the RAM is faster than what the moboard is rated for, but I was told that the BIOS would detect it as 667Mhz RAM and use it without problems.

Opinions?

You should test the sticks using >>Memtest86+<<.  Test all sticks together overnight, or, a quick and dirty method, test the sticks running test#5 20x and test#7 20x.  If you get any errors, then you need to start testing individual sticks.  Would you also provide a more complete list of you components including the PSU and the amps on the +12v rail.  Read the >>Posting Guide<<.

667 is supported, however, 800's are backward compatible, so maybe just a DRAM voltage increase up to 1.95V's may be needed since filling all the slots with 8GB total.

Sorry for late reply.

Video card is an MSI N460GTX Cyclone 1GD5

Mouser MUS-500-TW power supply
Total peak 500W
Total output 450W

DC Output    +3.3V      +5V        +12V1       +12V2          -12V       +5VsB
MAX A              30A       28A           17A           15A             0.3A        2A

Bumping voltage up on RAM wont fry it?

1.95V is certainly not a critical setting.  Don't worry about damaging your memory with 1.95V.

Well I tried it and it didn't work.  Got a black screen at bootup and then after putting old memory back inside I had to do an OS repair.  So much for that idea.

It has been suggested to me in another forum that the root of my problem lies in the less than stellar PSU installed in this PC.   Before I drop another penny into this PC I would appreciate a second opinion.  A new PSU would be the cheapest fix I think.  My PSU specs are listed in earlier post.

A Corsair single +12V rail VX550 or TX650 would be a nice addition, but before running out & spending any money, do you have a local shop or a friend to borrow a PSU to test with?

Perhaps, I'll ask around.

Oh no! things have turned out badly now.  My son was watching a DVD on this PC, which had been working fine with the 2GB of RAM installed.  He shut the PC off by hitting the main power button and after I peeled myself off the roof............... I tried to restart the PC.   Fans spin up, blue lights on the case come on, but no HDD whir, no signal to the monitor.  It just sits there.  Motherboard or bad PSU, I just don't know how to begin trying to fix this.

Did a CMOS reset by pulling out battery and shorting the terminals.  BIOS went back to factory default and it booted up.  Think my kid pushed the sleep button on the Microsoft keyboard and the PC would not come out of its slumber.

Took it to a friend of a friend who worked at bestbuy Geeksquad (hey, you do what you have to).  He checked everything out PSP, RAM, and could not get the OS to boot with the 8GB of RAM installed.  He got the same errors as I did, the black screens, the OS repairs.  Basically, he was stumped as to why there is a problem.
