I want my OC back.....

[Lester_McGee]

Hi,
I've been running my 2200+ at stock fsb (133) and a 15x multiplier for a core of speed of 2.0ghz for about 2 weeks. System was solid as a rock. I've been reading how the power supply is "the heart of the system", so I decided to replace the cheapo generic unit that came with the case with an Antec Smartpower 400. Slapped that puppie in, and off we went. After running for a few hours, I decided to run 3dmark 2001se again to see if all those extra watts were buying me anything. As soon as I got to the High Polygon test (the one with the dragons on the carousel), the system shut down and the MB was going "wee-ooo wee-ooo" thru the system speaker. I restarted, and tried again. Same result. I set the multi back to stock (13.5), and the system benchmarks fine. I thought the old PS might have been running a little "hotter" on the voltages, even though the Abit utility showed the Vcore to be the same. I tried to bump Vcore up by .1v, the system wouldn't boot. I'm open to any suggestions, or guesses as to why one PS will allow me to OC, and another won't. I *really* want my extra 200mhz back

possible that you got a faulty Antec. What are the voltage readings in the bios?

Specs on your system would help.
Re-seat your vcard and memory.
Oh ya..Welcome to the forums.

System specs-
Abit AN7-S, AMD Athlon XP 2200+, 1 gb (2x512) Kingston PC2700 DDR, Chaintech GeForce4 MX440 /128mb. Onboard sound and LAN. Antec Smartpower 400.
Already tried reseating the ram, video, and all connectors, thinking I bumped something swapping PSU's out. Also tried unplugging the my second HD, cd/r, dvd-rw, and floppy in hopes that one of them was pulling a voltage down. Can't get a voltage reading, I'm at work and the system's at home. What confuses me is that short of running the benchmark, the system runs fine. I can do hours of Morrowind, or EE, or Dungeon Siege, everything is as stable as I could ask. It's only when that particular test in the benchmark runs that the system craps out.

In your bios, do you have the "agp" selected, not the pci?

Good news, and bad news...I checked, and sure enough the "init display first" was set to PCI. I changed it to AGP and ran 3dMark 2001se again, still at default fsb/multi settings just as a baseline. This time it crapped out at default.
So my conclusion is that the problem lies with 3dMark, and not the system so I'm gonna set it back to 15x and just not benchmak it :-0
