Does anyone have an 850E chipset on their motherboard?

Are you sure you´re running Windows? :?

NT 4 SP 6 or SP6a, or NT 3.51 SP5 will manage months of uptime sometimes, on a system that isn't doing more than a couple things at a time.

On the other hand, I've never had OS-related downtime on any of my LINUX boxen - hardware failures, extended power failures, hardware upgrades, and a couple of ID-10-T errors on the part of the owner, like when I accidentally deleted the entire /lib directory on my firewall/NAT box - and it kept running for 2 months after before I got around to fixing that. It *ran*, just couldn't launch any *new* applications....

Well I broke down and purchased a P4 2.4b. Now I need suggestions on a good motherboard.
thanks in advance

George, are you doing anything particularly unusual for cooling? That may be whats needed, on a hunch.

Hi! I've one P4T533 with 2X256 Mb Rambus PC1066. My 2.4@2.6Ghz P4 is working fine... 24X7...

I can't run prime95 for more than a minute let alone 24 hours.
Using my P4T533 with 2x 256 232pin 4200 Rimms on winXP

just about ready to throw the hole thing in the skip :(

Don't give up Diggs, you just need to find the offending part and return it. Since you are dying quickly, it isn't heat related. Most likely it is bad RIMMS or inadequate power supply. Have you tried underclocking? Can you set just the ram to run at a slower speed? Have you run any programs that look at your voltages when prime95 is running?

From what I heard there could be some problems with some RIMM and some of the older P4T533. I would try to update the bios as I believe the newer bios solves some of the incompatibility issues with some of the RIMMs.

thanks for your help guys, but this is the story of all my heartache.

I've had the Rimms replaced 4 times, the PSU & CPU once, and just last week the motherboard too. All with very similar problems.

fails memtest 86 at every turn prime95 & 3DMark also.

Can anyone give me an underclocking guide.. I haven't got a clue in this area :?

And is the following PSU suitable for my setup?
Enhance ENS-0246 / 460 Watt Power Supply
[AC input: ¤ 115-230 Volts, ¤ 10/5A, 60/50Hz, with Power Factor Correction and outstanding DC output as follows:
¤ +3.3V @ 40A ¤ +5V @ 45A ¤ +12V @ 28A ¤ - 5.0V @ 1A ¤ - 12V @ 1A ¤ + 5Vsb @ 2A]

cheers again,

There is a ***HUGE*** thread over in the Hardocp forums about this particular board... Maybe that might have some help?

Hi Diggs! As I told you, I've a MoBo like your with a 2.4B Ghz cpu. BIOS rev. is 1005 and OS is winXP. Your system is surely better than mine (that should be a good piece of news), since this PC is quite simple and not very well balanced: it is equipped with extremely poor both audio (SB) & video (S3 Savage) cards. Using an old 350W Chieftec psu and stock rimms (1X256, Samsung), it runs "prime95-solid" till to 2.8 Ghz (Vapochilled).

Since the test fails immediately and at every run, memory sticks may be between first suspected. Did you always use the same kind of memory (same brand or stick with the same kind of chips)? Did you try using just one memory stick?

Did you try using different video cards or different audio cards (or without any audio card at all)? May be there are some unknown incompatibility... Does tests fail even if you boot Windows without loading any driver (by pressing F8 at bootstrap)?

Since the PSU I'm using is less powerful than your, your looks to be a good one and this MoBo has a good power supply circuitry, I think you should look for the guilty somewhere else...

As George said, do not give up Diggs and take us up to date!
