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.

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!

That's totally up to you, when working with clients all I can do is make suggestion, just like here, they (you) have the final say...;) will add though, when something is contentious (and depending on how well I know them), when their rig is done, I let them play with the components they picked...and then often throw my picks in, more often than not they want to make a change...which is a good thing, I know they'll be back and when they leave (or I leave) I know they are happy, which is what it's all about, the parts they had picked can always be used elsewhere or returned if it's something I really don't like...regardless, 2400 is a good freq, I'm sure you'll be happy with them.........until you leave the Dark Side and try GSkill ;)

So Tradesman, what would you say about that lol? I mean, if you can suggest any G.Skill kits that does 2400 CAS10 stock just like the Corsair Vengeance Pro, I'll go with it, since G.Skill memory is relatively cheaper. But hey the other guy there managed to OC the Corsair sticks up to 2800 12-14-14-35 @1.65v, so no overvolting needed in this case.

I just hope to get these sticks to work at 1866/2133 CL9 or 8 with stock voltages.

Just popped a CPU-Z shot on GSkill here:

http://www.gskill.us/forum/showthread.php?t=12559

as far as what they are saying, looks like Pro Corsair or maybe they've learned some since a year ago, also obviously there is no comparison that can be made from something done a year ago on a totally different platform.....I sort of find there statement hilarious as everything is totally out of context...a year ago, different platform, etc....this is typical of a number of 'experts' that write abot DRAM

Update: went ahead and read the article, what they did, not only was this tested with the newer Gen CPU/platform which handles DRAM much better, the 4770K (a decent one) can handle up to 3000 sticks, the 3770K ( a good one was generally stuck about 2800) this was done with only 16GB, not 32GB....and like they said (a brand new model) Corsair didn't have any 2400 high density sets out a year ago.....In 32GB their set is $50 more than the Tridents also

I just went checking the 2x8GB 2400 Trident memory kit (F3-2400C10D-16GTX), and on the G.Skill official page it says it does 1866 CL8 and 2133 CL9, but am not sure it will be even compatible with my current set.

Oh wait lol what are you actually trying to say here? Is it that TridentX might be better at OC'ing than the newer Corsair Vengeance Pro? Is that it? I don't think so, huh?

Yeah, your prob right, they must obviously be crap sticks...based on what? One article....But, you are definitely right......in your own mind, obviously you don't pay attention to the rest of the world, if Tridents are such crap is there a reason they set a number of world records at Computex last month...of they used the same basic platform these guys did a 4770K

It was all over the net:

http://hwbot.org/news/9669_g_skill_achieved_6_overclocking_world_records_during_live_oc_event_at_computex_2013

http://www.eteknix.com/g-skill-bag-six-overclocking-world-records-from-computex-oc-event/

http://www.tweaktown.com/news/31095/g-skill-breaks-six-world-records-during-live-oc-event-at-computex-2013/index.html
and done with a few different mobos and 4770Ks

But you want to make statements on a HASwell/Corsair vs a Ivy Bridge/GSkill it's apples and oranges....as stated before you can't compare the results...and it's hilarious you even try, same as them

Oh no wait calm down a little bit lol. I didn't mean to say Tridents or G.Skill is like crap, of course it ain't. Just looking for an unbiased opinion, that's all. :)

But anyways I think I'll just have to go with Corsair this time, since I am sure the kit is compatible with my rig. Might post some results later.
