Could I expect to be able to hit 2.26GHz with this chip? I want to put it in my KT7A-RAID. Would this be better than getting a 2100 DUT3C? I'm leaning towards the 2100 because it wouldn't require any mods.
They'll probably oc the same. The 1800 is a dlt3c which is very good but its an early week 0304 where results are mixed. The xp2100 dut3c 1.60v also had some good and bad weeks so its basically a 50/50 crapshoot for you.
I'd buy the xp2100 (higher resale value) if the prices are close. If the xp1800+ is much cheaper then you may as well get that instead.
