After reading this, it may lead to think Ver5.29 kits, which contain Hynix memory chips are somewhat better for overclocking, but how is that so? Also, do you think that compatibility wise the high-density Samsung chips would have an advantage over Hynix? What about the timings working at 1866MHz or possibly 2200? Which would be able to sustain the lowest CAS latency working at those frequencies?
My system rig is FX-8350 with the Sabertooth 990FX Gen3 motherboard.
Thanks!
The common practice on modern DDR3 memory is voltage only playing a role when it comes down to lowering the CAS latency with three other primary timings being voltage-unaffected. As it is known, Samsung chips (like the used on our Vengeance - Ver4.21) are able to react to voltage changes up to 2.0V even though we are not fully certain whether values above 1.8V are suitable for daily application. Either way, we could still get our kit to work stable at 1000MHz 7-9-10-27, 1100MHz 8-9-11-27 and 1200MHz 9-10-12-30 none of which were possible with a similarly rated G.Skill TridentX set we tested a year ago. As usual with memory based on Samsung high-density chips, no full stability above DDR3-2500 possible, however, we were able to boot and pull a SuperPi 32M at 1300MHz with CL9 just for our own entertainment.
I wonder why Corsair is sending out the Ver4.21 kits for all the reviews. I picked up two retail packs of the 2x8GB and they are Ver5.29 Hynix MFR and I've been able to run all four in my Z87 board at DDR3-2933 12-14-14-35-2T 1.80V for single Super Pi 32M. They'll also do 2666 11-13-13-35-2T and 2800 12-14-14-35-2T 1.65V.
