Windows 7 64bit doesn't like something

[Elcura]

And apparently this something is causing it to crash and generally be an asshole. 32 bit works fine, so I'm wondering what it is that's causing all the problems.

RAM: Corsair 6GB (3x2GB) DDR3 1600MHz XMS3 Memory CL9(9-9-9-24) for i7 motherboards

PSU: CoolerMaster 600W Silent Pro Modular PSU - 50A Single Rail 9x SATA 2x PCI-E

GPU: PowerColor HD 5770 Play Edition 1GB GDDR5 DVI HDMI Display Port Out PCI-E Graphics Card

CPU: Intel Core i7 920 2.66GHz Socket 1366 D0 stepping 8MB Cache OEM Processor

HDD: Samsung HD103SJ Spinpoint F3 1TB Hard Drive SATAII 7200rpm 32MB Cache - OEM

Fan: Noctua NH-U12P Special Edition Socket 1366 Dual Fan Heat Pipe CPU Cooler

MB: ASUS P6T Deluxe V2 iX58 Socket 1366 8 channel audio ATX Motherboard

So that's what I have, any help would be appreciated, as I'd hate to have to replace something just to get 64bit to work...

Try unseating RAM, are you overclocking, etc, etc.

[Cephius]

Really need more information. Are you blue screening or just freezing? Any error codes? What do you mean by "being an asshole"? Did you do a full reformat before putting 64 bit on it?

[Elcura]

Yeah, did a full reformat, not overclocking or anything, getting a BSoD that states there's a problem with memory management, I think the code was 0x0000001A.

Basically, I reformated, installed 64 and everything was good until the last stage, it blue screened and shut down, when I turned on again it completed the installation but of course, you can't feel good about that. Occasionally (especially when restarting and shutting down, powering up) it would freeze.

I would do what kuronosan said, start testing your ram sticks.

32 Bit could be working cuz is not using the whole 6 gigs.. win64 is hitting a bad module maybe..

[Elcura]

Alright, I'll try that out. Worst case is that I need to get new RAM, oh well, that isn't a big issue.

At least I hope that's the worst case.

[Cephius]

If that's not it, it could be because your power supply isn't supplying enough juice to power the extra RAM modules when called upon by the OS. If memtest86 pans out, consider a different PSU.

Single rail with 480W max on 12v out.. should be plenty I would imagine.

[Cephius]

You would think, but if it's not the RAM itself I can't think of any other reason.

[toonces]

hmm from what i read.. cephius could be right also. Some people actually fixed it by upgrading PSU.

[Minions]

I've generally seen it in most cases to be a ram problem. In my past experiences anyway. It is also problem as other have said that there is a lack of power, you can pick up a cheap psu to check it, or rip one out of another computer.

[Sonomaa]

that sounds very much like a ram issue

[Elcura]

Hmm, I guess the obvious choices are to look at the RAM then the PSU. Would it likely be a fault with one of the sticks or the type of RAM I'm using? I would think it's the former, but I'm not expert.

[Kaisha]

A bit off-topic, but is there a reason why RAM comes up faulty more commonly than other parts? I know I've had faulty RAM before, my brother has on two of his three computers (don't ask), my mother did on a PC she bought new (lol), and a friend of mine has also.

You use more of it? Perhaps? You use 1 PSU, 1 CPU, 2-6 sticks of ram. That's not to say its entirely more faulty than other components. I've seen my fair share of faulty PSU's, especially ones that don't reach nearly the levels that they are supposed to, or simply frying. Good thing is that most motherboards will stop voltages from frying everything these days.

Also ram is cheaper (most of the time) than the other components.

One of the rarer things that could cause this issue is a bad ram slot on the motherboard, but that's extremely uncommon, and would require some real force when installing the ram to damage that.

RAM is much more susceptible to static damage or chips/soldering errors because of the frequency of production.

I've yet to buy a set of RAM sticks for a desktop I built where at least one chip didn't need to be RMA'd.

[Cephius]

I guess color me lucky because I haven't had to replace a single RAM chip in over 10 years of buying components.

That said, information is constantly being written to and read from RAM modules, and the OS depends on using that information to operate. If the slightest timing is off, or section of RAM is bad, it'll crash the OS.

[DAKPluto]

Maybe it's just old fashioned of me, but RAM in anything but pairs/quads bugs the hell out of me >.>

[vanidin]

I would boot it with one stick in at a time, as that's the easiest way to find out if your have a bad stick, either memtest it or load a ton of apps to push the memory usage up.

If all three sticks seem good, you may possibly have a bad slot or a bad psu. to test the slots you'll need to either use one stick of ram and run the memory tests in each slot one by one, or borrow memory from a friend (3 sticks to test the 3 slots you would be using).

The power supply can't be ignored just because the 12v rail has a nice amp rating. Is the voltage coming out of the psu stable? even though it's brand new it doesn't mean there may be problems with it.

Double checking the voltage your bios is giving the ram is also a good idea, it's always possible the mobo is undervolting it.

I've seen some posts in tech forums where people have had to slightly increase the cpu voltage to get their memory stable, due to the integrated memory controller, not necessarily sure how necessary that is but it may pay to poke around in some techie forums and see what discussions you can find.
Good luck!
