I have two sets of Ballitstixs Tracers. One set love 3-3-3-9-1T. They will run that at 800Mhz with 2.2v. Can get them up to 850Mhz with 2.35v. They don't really like running 1200 and up. The other set doesn't like T1 but will run 3-3-3-9-T2 at 2.3v. Though, the second set will run 1200 5-5-5-15 with 2.15v. I think the first set are GMH and the second might be GKX. Just a guess, since all the IC say are "ballistix" on them. Anyone know how to read the -18F and -17F that's on the ICs, as to tell what IC they are?
