Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
Either of them should overclock VERY well. They only come in E0 and G1 stepping, I have a Celeron D 320 with an E0 stepping and its running at 3.8 on default voltage. I'd imagine that the G1 overclocks just as well if not better.
The only problem is that you're going to need to be able to run 233+FSB for 3.8+ghz. So if you're that interested in hardcore overclocking it, look for ram that can handle the FSB 1:1 like PC4000.
I think its a win-win situation with the Celeron D 315. No matter which stepping you get, its going to be a good overclocking one. Post results when you get everything up and running, I'm very interested in this, especially if you get a G1.
Oh shit, I just realized that the 315 runs at 2.26ghz. I was getting it confused with the 310 that runs at 2.13ghz.
Intel made those in C0, DO, ane E0 cores. Looks like you got lucky and got one of the latest ones built using the E0 revision. I still think that you'll have little trouble hitting 3.6+ghz.
