Stop errors and AMD 64 bit processors

  Deb-232479 14:40 02 Feb 2006

Has anyone else had problems with stop errors in a 64 bit system? I had :-

AMD 64 3200+ processor
Asus A8V Deluxe socket 939 mobo
300w case
Akasa low noise cpu cooler
512MB PC3200 Aries RAM
40GB 8MB cache WD Caviar hard drive
Lite-On 16x DVD-ROM
GeCube ATI Radeon 9250 256MB AGP Graphics card
32 bit XP Pro

From first switching on I was plagued by a 0x9C stop error "machine_check_exception" beginning dump of physical memory.

I sent the machine straight back, but this has really put me off 64 bit as I don't understand what was wrong. Any suggestions? Do you find 64 bit stable? Where do you think I should go from here?

AMD 64 3800+ (939 pin),Asus A8N-E Motherboard.
Has been fine, had problems with Motherboard & other parts, but otherwise happy with the processor speed.

The new Dual core processors coming on-line look good, always worth a look round this and other forums to see which make of machines are stable.

Same processor here - no problems in over 6 months.

However in your case - 0x0000009C: MACHINE_CHECK_EXCEPTION

This is a hardware issue: an unrecoverable hardware error has occurred. The parameters have different meanings depending on what type of CPU you have but, while diagnostic, rarely lead to a clear solution. Most commonly it results from overheating, from failed hardware (RAM, CPU, hardware bus, power supply, etc.), or from pushing hardware beyond its capabilities (e.g., overclocking a CPU).

thanks for the info.

doc999, is your memory branded or cheap? How about your graphics card too? I wondered if it might be my cheap components?

PaulB, yep I'd read some of that stuff. I figure I might've had some incompatible hardware, but it's impossible to identify what. Can you tell me what memory and graphics card you have?

I also wondered if my 300w psu was up to the job. Did I really need a 400w? What is everyone else using?

300w psu is propably most of your problem, with the power requirements of your hardware, even a 400w is a little light these days, i would suggest a 450 or higher.

  Deb-232479 17:10 02 Feb 2006

Really? I'm way off mark with the psu then. The idea was, once my system was proven to be stable, I would throw in a few extras. So I would have 2 optical drives and 2 or 3 hard drives. What psu for all that?

  Jdoki 17:16 02 Feb 2006

At least 450W, and go for a decent make. Tagan being my fave.

I have the following set up and with a Tagan 480W PSU - proving stable over the last few months (touch wood!):

AMD64X2 3800
MSI mobo
Overclocked GeForce 6800Ultra with Zalman cooler
Two Optical Drives
Two SATA Hard drives
4x 80mm fans
Loads of USB devices

Maybe I'll have to build it myself then, because looking at pre-built systems, they all seem to have 300w psu's. And they're never quite what you want, are they?

My husband thinks I shouldn't do it myself because I'm talking about good quality components for once, rather than the recycled stuff I normally use. He's worried about the lack of a clean-room and that I might kill it with static. Come to think of it, I'm a bit worried myself. I can't afford to buy the bits and break them.

Any advice?

would a midi-tower be okay or do I really need a full size tower?

The modern 64 bit processors actually use less power and run on lower voltage.A good spec 380/450W with PFC should be fine and allow room for some expansion.

As well as Tagan, also have a look at Seasonics S12
430W with active power factor correction and a 120mm
Fan, a really quiet PSU for around £60 if you shop.

I have used 2 so far in 939 skt boards and you get a lot of cabling extras with them including leads to vary case fan speeds.Bought here click here

Hi eBay's Sidni7, the memory is branded, the graphics are 128MB ATI 800X PCI-E, i dont think it's because of cheap parts, more likely due to poor build.

But apart from things going wrong it's been very stable for the last 2 months, in fact the best it's been!
