Problems with Overclocking my e8400

[Tumdace]

got it running 2.0 for memory, so thats 1:1... 378x9 for 3.4ghz.. should be good for me i guess... 1.365v.. +0.3v for the ram, +0.1v for the fsb, northbridge. and pci-e.. runs stable.. had orthos going for 5 min so far.. no errors. but i think im gonna run it for longer when i go to bed tonight..

theres a totally seperate problem im running into that i think has to do with my freaking headphone amp shorting out my xfi and causing my pc to reboot... my xfi doesnt work ne more.. no sound whatsoever.. and i unplugged the wire going from my xfi to my headphone amp, and plugged my headphones directly into the xfi.. when i got back up and checked the screen.. the pc had restarted...sound doesnt work now.. i think i might have to replace it..

might have touched the wire that was plugged into the amp onto my case.. u think my headphone amp has some sort of short circuit coming from it? or is my xfi just screwed? i mean i can still see it under device manager (unless thats just a driver) but i cant hear ne thing...

hmm maybe 5 min wasnt enough for orthos.. because i was surfing the web and my pc just froze.. unless should i take that xfi out.. maybe its causing the problems...

I have not had time to read through all the posts here...but...for an E8400@1.35 you should be able to have no issues with stability at only 3.4. My E6750 is rock solid at 3.6 with the same volts. something is off.

If I were you Id consider trouble shooting the system top to bottom with a fresh install of windows-if you have any parts to swap out or your close to someone who can lend you a cpu and mem, psu, gpu to see whats going on that would help. take the soundcard out for now and hopefully you will find the issue soon. good luck.

Take out the sound card, we'll troubleshoot later. In order to be called "stable", an oc'ed computer has to run Orthos for 12 hours.

k well ill try overclocking again tonight and running orthos.. but for now im leaving it at stock..

no sense in running overclock if i cant test it properly with orthos right away..

whats weird is.. my bios used to have default timings of 5-7-7-24 for my ram.. suddenly its 5-5-5-18 now...

i think i might have had stability issues because of hte 5-5-5-18 at 3.4ghz..

i really dont think my cpu can be overclocked with those low of timings.. and with a 2.0 multiplier i can get like maybe 800mhz ram... either i run a 2.5 and ignore the 1:1 ram divider or just leave everything stock and have 1066mhz, which is essentially what i want..

Tumdace - been doing a little research on other sites, apparently this is not an uncommon problem for people to be unable to change FSB's on Giga-byte boards. It is usually solved by unplugging the system and removing the CMOS battery for 20 minutes or more, then resetting the bios using the clear CMOS jumper. Why so long? to make sure your power supply capacitors are totally discharged and are not trickling power to the board. The load optimized settings and try adjusting from there.

Give this a shot, see if it works.
