Opteron Socket939 Overclocking Discussion Thread

[orbitor]

Well I got my system together and quickly brought the cpu up to 2.5GHz at stock volts. I have little time for detailed testing at the moment unfortunately

Can someone help me out with my UTT (2x512MB) settings? Using optimised defaults (like 2.5-4-4-7 iirc) the RAM runs fine at 225MHz+. But changing to 2-2-2-5 or 2-2-2-6 seems to be a no go at 200MHz 3.0V - errors in Test 5 of the built-in memtest86+. All other memory timings were left at the 'optimised' defaults.

I'm not at the PC now, but can post all the timings etc. this evening.

PS. Should 3V be enough to get 2-2-2-5 timings at 200MHz?

you should really have a system spec in your signature.....you need to give us more detail on your system......should be able to work at 3V

Done - I know I didnt' supply that much info, but just thought maybe someone else had already had an issue with the default settings with UTT stuff when trying to do 2-2-2-5.

Try these settings Value VX (Winbond) - T_M style
3.0V at 200 should work easy

Thanks mate, will try them tonight. Basically I'm just hitting 'Load Optimised Defaults" then adjusting the 4 primary timings to 2-2-2-5, and it won't pass test #5 on 3V. I thought maybe the defaults were suited more to say TCCD and weren't playing nice with the UTT.

Yes I know I've got a lot of catching up to do, but this is my first A64, and it's a world apart from K7 overclocking

Those setting in the link should be simple for UTT to hit.
Being in Brissy, maybe hit up Eva to test the sticks if you still have no luck?

wonder what's the chances of seeing these CABNE 0540 weeks looks like aggressive speed binning has started http://www.xtremesystems.org/forums/...00#post1100200

Got confirmation from overclockers.de that my Opteron 144 Cabye 0536 is on it's way.
Anyone who knows if the 0536 is a good OC? A little question, I'm about to order a new motherboard for my opteron and want to know what mobo I should choose? I have AGP-bus so I wonder if DFI Nforce 3 is any good oc? What about Asrock dual sataII ?
