opteron v. newcastle 3800+

post #1 of 4
Thread Starter 
I currently have a newcastle 3800+ which i can oc to about 2.75 stable. For some reason it hits a ceiling around 2.8 and there is absolutely nothing i can do to get above this. My superpi scores are at best just below 31 at 9x multiplier and 300ish fsb. This is all at 1.7 vcore and 3338 timings. With this current configuration and performance is it worth upgrading to a 146 or 148 opty for increased overclocking performance? Furthermore will these optys have a good chance of hitting 2.9ish ghz?

I'm not really sure about Optys. I know that I can push my 3700 SD past 3 GHz. I think the Opterons are very good overclockers, but I'm not quite sure. Wait for an Opty user's response...

it depends on the stepping you get, i had a 148 with cabye stepping and i could pull 3.0 , 3.1 but it wasnt stable to much and that was with my asus av8 deluxe

my opti 170 is doing 2.7 stable and i could go higher if my mobo would go above 1.5vcore

the average i guess for the single core 148's is like 2.8 i think so the only advantage would be the imb cache

also i think the new je steppings are pretty good to

upgrade to an opteron....at the prices they are running right now, it is an excellent choice. I'm running 2.9 w/ 1.5v air (264x11 1:1) and my 1M time is 29s. The unfortunate thing about newcastles, they dont OC at all...
Do what you want, but I love this chip...
