However, I do want to speak honestly and say that there were ways to reduce the flicker. This would have, however, required us to cut down on the types of light customization you've all enjoyed since day 1 and we felt this would not have been acceptable whatsoever at all. I think for certain profiles like rainbow gradients look much better with all the colors available. Despite some of the side effects of this product, I still believe that in terms of customization, this keyboard delivers an amazing experience that can't be matched by our competitors and we still have more plans to come to go beyond what is offered today. I think as we get closer to releasing what we have planned, the issues with some of the color on this keyboard will be overlooked with the advance features we're going to implement.
Well then would you consider having an option with less colors? Right now you should be able to achieve 24bit colors (~16.8million). Before you had 512 colors which was beyond stupid, but if you added an option for 16 bit colors (~65 000) that would be more than enough for most if not all users, and hopefully it could help achieve better transitions. This keyboard isn't a monitor, and subtle color difference don't really show up. I can instantly tell how bad 512 colors was compared to what I see now, but I'm guessing 16bit would be almost the same as 24bit. The reasoning for me, is that even now with 24bit colors, the housing is doing a poor job of diffusing the light, and the colors are far from perfect. That being said, I don't think 16bit vs 24bit colors would make a huge loss visually, but maybe it could help achieve better transitions when having to deal with less data flowing?.. I dunno.. Before the obvious issue was the lack of colors, thus the transitions where very poor. Now we have more than enough colors for having fluid transitions, but the controller can't keep up.. I think there is a middle ground here, and I'd love to hear what the developers think about that.

I think that would be an acceptable compromise between not actually having 16.8m colors and not having the flickering that occurs. 16.8m colors is nice and all but isn't worth the flickering that happens when you try and use them in something that is more complex than a simple single-key type lighting profile on a black background. I'd be willing to bet that 16-bit color could be introduced without all the flickering, and that it'd still be visually appealing.

The flicker really doesnt bother me at all it is VERY slight its certainly not eyecatching enough to be worried about, i do love my k70rgb and i know nothing else on the market matches it, i know ive tried!

Now if corsair could make a seperate piece of software called "WCU" or whitelevel calibration utility i would be over the moon, a seperate piece of software that allows flashing to the keyboard your own personal white level settings for the keys as everyones will be very slightly different in different places.

As far as keyboards mice and ssds, i have ALWAYS bought corsair as i know theyre the best out there.

And reapex your sig picture is awsome! i wish corsair would make a transparent keycap set!

I do love this keyboard but the initial software and now the apparent hardware limitations are insane. Corsair clearly went into this project only for the money (Well duh), without researching what the components used in these keyboards are capable of.

Have already requested a return via the kbinquiries address. Let's see how this goes. Not sure if I'll ever buy another corsair product.

Mine is exactly like that, 16.8m colour mode seems unusable right now...

While I agree with you from the consumer end, the perfect world scenario would be what? Having them come out with a newer version with the issue totally solved, give us all refunds or free upgrades, and use the new one. All they would be doing is shooting themselves in the foot financially, though.

Even if they came out with another keyboard that had this fixed, we are looking at higher costs for better controllers and possibly little to no MX RGB Blue yields. I'd only want Blues anyways. Then, everybody would be complaining that they just bought a keyboard, didn't do what it was advertised to do, and feel they got ripped off.

It's kind of a lose/lose either way. I'm sure more vendors will come out with MX RGB keyboards, or do custom switches like Razer. The best, most-honorable thing in that case for Corsair to do would be to honor refunds if another vendor did come out with a better-equipped keyboard - at least for purchases before they updated product descriptions.

In the end, I think or at least hope that one of the lessons they learned is to wait before announcing products until everything is fleshed out technically. Small technicalities will kill product launches if they do not, just as we see here. The wait before the release was really too long anyways, in my opinion.

I`ve set all keys to white, but any key pressed will change from white to red and back to white again over 4 seconds. Just pressing a single key will make the rest of the keys flicker, almost like a faulty florescent lamp.

Looks like this guy should be employed to design K** RGB Mk 2.....

Considering that the palette supports 7 (possibly 8 but I'm not certain) independent PWM values at once, that means you only have to update the palette every 7 LED frames, or 7*35 = 245uS. That is more lenient than the 115uS I came up with earlier. Since we know now that the SPI clock frequency can be up to 10MHz as opposed to 1MHz, that cuts our previous bit time of 1uS down to 0.1uS. The SPI write takes 16 bits (making my 2-byte assumption correct) which is 8 bits for write flag and address and 8 bits for data. It looks like you must specifiy address for each byte written. 16 bits * 0.1uS = 1.6uS per write. However, now you're updating the entire palette rather than just one LED, so that becomes 1.6uS * 7 = 11.2uS to update the entire palette (not including delays between transfers). Now you need to do this three times because there are three drivers to update. If they wired all of them on the same bus, this takes 11.2uS * 3 = 33.6uS but if they are using three independent SPI busses this could still only be 11.2uS plus a bit of processing time. That means updating 11.2uS over a period of 245uS, which seems more reasonable. This still seems to be a very high demand on the CPU and will require perfect synchronization, but if they optimize well it does seem doable, though pushing the limit.

James, what would you say to reassure customers who doubt Corsair's ability to implement advanced software features when other programs like Link have frankly been a disaster from day one?

The 16.8m update has fallen short of the no-compromise fix many of us were hoping for. Customers have waited months for a feature than was written on the box and the solution is less than ideal. In that time both of your main competitors have released similar offers that exceed the capabilities of your products in many ways. Is there anything you can tell us to help us believe these keyboards will be improved by powerful software that works correctly and is released in a timely fashion?

For me, I love the fixes and my keyboard looks awesome. The flickering I have noticed (even duplicating patterns the complainers are using) On a scale of 1-100 with 100 being as bad as some people make it seem, is a weak 5. Totally acceptable and I can tell you if it came like this out of the box (which it should have) this board would not being beat up right now by some, rather it would have been praised by everyone.

Corsair --> Great Job but it should have been this way from release.

I can now look forward to even more features down the road since Corsair has a grasp on CUE and the firmware.

Default updating firmware

Is it possible to force update firmware? because I'm getting "Failed to update device firmware" with the new CUE version.

We can Only hope that there is a V2 hardware and we are offered an upgrade for a MINIMAL fee for being the beta testers.
IF you do not like the keyboard you may contact Corsair at KBinquiries@corsair.com and ask for a refund. There isnt going to be a option to send the K70 RGB back for a new v2 for a "small fee".

I am just pleased that I have a keyboard that doesn't appear to crash with Steam now (or crash randomly now). While 16.8 million colors is nice, IMHO software crashing was by far the biggest issue. So, with the latest fix, I am a happy customer :)
If 16 bit colors are possible without the flickering, I would say go for it. Just make sure that the CUE software remains stable :)

No "g-sync" like module to solder onto our current keyboards? =P

And I'd appreciate it if you would stop with the "STFU and return the keyboard if you don't like it" responses. It isn't very helpful. People have legitimate concerns and are venting on the official forums about an expensive product that does not function as advertised.

I've personally put in for a return and am hopeful they'll have this resolved with their next iteration. The other problem is now I have a set of translucent keycaps and no keyboard to put them on. =/
