charloscarlie,
Is this the second CG that you have tried that's a clawhammer? If that's the case, then may be there's something to this speed capping business. Or on a less sinister note, the 1MB cache makes it really hard for the clawhammer to overclock stably over 2.3GHz. The CG newcastle overclocks like a demon even at stock voltage.
Does anybody else have experience on OCing a clawhammer CG?
I can OC my 3200+ clawhammer CG to 2.4GHz but it would fail prime 95 after 10 minutes. It's not the memory because I have tried everything from the fame OCZ 3500EB to the Crucial 3200 8T single sided. But interestingly enough, the crucial is cheaper and performs better than my OCZ in benchmarks. WTF?
My current stable setup right now is 2.31GHz (230 FSB X10) with 1.60 core voltage, 2.8 vdimm, 3x HTT, 1:1 FSB:RAM (running with Crucial 3200 8T). Man, I tell you this crucial ram is great. I bought 2 sticks of crucial for $156 total when newegg had it on sale for $78 each. I got a 4 fps gain in performance in DOOM 3 over the OCZ with the exact same settings. What gives!!!! But I'm happy with crucial nevertheless.
