In a new article published on the Dutch version of Hardware.info, the members of the Hardware.info Pro OC team have a look at what the four dominant DDR3 ICs available offer in terms of overclocking capabilities. Nedernakker pulled out a set of G.Skill TridentX DDR3-2666 CL10 2x 4GB (Samsung), Corsair Vengeance Pro DDR3-3000 CL12 2x 4GB (Hynix), G.Skill Pi DDR3-2000 CL6 2x 2GB (PSC), and G.Skill Trident DDR3-2000 CL9 2x 2GB (Elpida). Using the latest Haswell Z97 platform powered by the Pentium G3258 and MSI Z97 MPower, the Dutchman compared the four ICs in bandwidth and SuperPI tests.
The article rightfully notes that none of these kits are currently available in retail. So if you want to acquire one of the kits, you'll have to search Ebay, Craiglist, or enthusiast forums. It's also worth to note that the kits used are not special binned samples.
In the conclusive lines we find that Elpida ICs are winning the AID64 bandwidth test, whereas Samsung ICs turn out to be very good for SuperPI. Take into account that Elpida ICs were EOL before the Z97 platform came about and that those boards were primarily tuned for Hynix and Samsung ICs.
