Is 500W enough for a AMD 9950BE?

[SketchMaster]

I just built up a new computer, and I think I made a HUGE mistake by cheaping out on the PSU.

Current system:

AMD X4 9950 BE
ATI 4850
120GB SATA
ASUS M3A79-T Deluxe
G.SKILL PI Black 4GB
Antec Neo Power 500
Antec Nine Hundred w/ 3x 120mm LED 1x 140mm

I was getting BSOD on Vista 64 for "MEMORY_MANAGER" and "CACHE_MANAGER", ran memtest with no errors, ran prime95 with no errors, HD scan came back clean and so did Chdisk and volts in the BIOS are well within range. What is most odd is the BSOD happen right after log on, if I can make it past that the system is rock solid for hours.

Last night I thought maybe I just had a bad install so I tried to reinstall V64 but I got a BSOD on that as well (0x00000024 or 25, can't remember 100%), I removed one of the sticks and that seemed to work, but I'm still not sure if I should blame the ram or not.

Any ideas guys?

Are you running the CPU at stock clocks and voltages?

 

[SketchMaster]

Yes, everything is at stock settings.

500W is more than enough.

Run Memtest. It may be that your RAM is having problems.

Test your RAM again for a long period and also test your hard drive.

Did you update to Service Pack 1? Vista doesn't properly install when there's 4GB of RAM IIRC. SP1 fixed that problem.

And just to reiterate:
[Testing the RAM]
Download Memtest+ v2.01, unzip it, burn the ISO file to a CD, and then boot from it, just like you would do with the XP install CD. Let Memtest+ run for at least three hours on each stick of RAM separately as well as test the RAM together. Go for a full 24 hours if you want to be completely sure that the RAM is not a problem. If you start seeing errors, than your RAM is defective or you have incorrect settings for the RAM.

[Testing the Hard drive]
Download the CD image of Hitachi Drive Fitness Test, burn the ISO file to a CD, and then boot from it, just like you would do with the XP/Vista install CD. Test the hard drive and see if any problems are found. DFT will run on most manufacturers' hard drives. Alternatively, you can use Seagate's SeaTools for DOS to test a Seagate or Maxtor drive. For a Western Digital drive, you could use Data Lifeguard Tools for DOS to test a Western Digital drive.

DVD is SP1 so I'm good on that.

I did get lazy with the memtest scan so I'll try it again and be a bit more rough on it. I didn't think to losen the timings until today and I think I saw a few reviewers on newegg that ran into issues with the ram not wanting to run at stock times unless they upped the voltage a touch.

The HD has already been scaned with WD software and I forgot to mention that I tried the reinstall on a spare drive I know works.

My Boss was nice enough to let me grab some RAM from our stock to test my computer and it seems to be working. ...For now.

Thanks for the input guys!
