can't seem to go past 140 or so stable, board undervolts about .5 but I take that into account when adding voltage. gone up to 1.7 and can't seem to get past 143 bus. anyone have any sudgestions? using arctic silver 3 and retail hsf. can't be mem, ran it under 1:1 and its corsair pc3000 anyways.
 
What are the specs on your chip? Also, how do your voltage rails look? If you've got a SL63X or older chip, then you may have just reached the chip's limit; however, if you've got a SL68Q, then you should definitely be able to crank some more power out of it.
 
its not an sl68 but don't think its the other either, was hoping for 2700 but guess I might have ordered from the wrong place
 
Its possible that low-qualilty onboard components could limit an OC, even with PCI/AGP lock. If you could possibly get your chips specs (they'll be on the retail box, if you still have it), that'd help diagnose your OC troubles.
 
he's hitting a wall ~ and voltage isnt helping so its gotta be something on the board....

the date of the chip will be helpful
 
well I got it running stable at 144 bus or aprox 2.6 ghz. ran prime95 for 10 hours, then 2 hours of 3dmark2001se, then 9 hours of both at the same time. everything seems to be working well.
 
Elminster, that's the setup I have except XMS2700 memory. With a SLX63X packed 9/14/02, retails hs, fan & even thermal tape it was an easy overclock. I have a pci ATA/100 card that caused some instability until I upped the vcore. All other settings are at default, so the lan & sound are enabled and memory voltage is normal. Also running w/ 4 hard drives, 2 CD-RW drives, a DVD drive, a winmodem pci card, and soundblaster live pci card.

Underclocking the memory allowed me to increase the fsb a bit. I'd bet that if I had higher speed rated DDR, put AS on and took out everything except my primary hard drive and my video card I could hit 155fsb for a 2.8GHz system. I'm fine at my current speed, but at some point curiosity will over come me & I'll uninstall all of the non-essential stuff to see if I can hit it 🙂
