Yeah, ok, it all looks great, but how do they work together outside of a test laboratory in a real world home built pc?

That question was answered very quickly, without any special fiddling about required beyond normal setting changes.

When the Corsair kit was installed, the usual 'Memory Has Changed' screen popped up. No big deal, a simple check in the UEFI/BIOS looked like everything defaulted to ensure a successful post and bootup. Yup, that's exactly what took place. Corsair took the right approach IMO to set the profile to default to DDR3 1333. At the next restart, it was a simple matter to set the manufacturer's recommended rated speed of 2133, CR 1, 9 11 10 27, tRFC 171 on Auto DRAM V. Posted and booted right up.

Yeah, ok, how about if 8GB isn't enough RAM for me?

Figured that might be a question asked. Here is the finding. To make it more real, often pc builders buy components at different times. This can be problematic, but that is best discussed on a case by case basis. Back to the answer. Purchased on purpose a kit from a different batch, even the serial numbers were way apart. After they were installed, the usual 'Mem. Change' screen again, but at F10 - Enter, it posted and booted right up! No increase of DRAM V. was required. In fact, with it set to Auto, the 'Read Only' actually shows the voltage to be 1.472v's (by meter, it was just below 1.50v's).

Note that CPU-Z X.M.P. for this RAM shows wrong. In the UEFI/BIOS, Memory-Z, it shows correctly.

Conclusion? I would say MSI mainboards and this RAM are going to work out just fine together. :biggthumbsup:







 
Wow nice rig Froggy ;)
How about Corsair RAM's performance in overclocking? Especially with your 3770K :) Ehm is it HU16E???

No problems were noted in the 44X - 45X range. Never tried them at this speed in an 'extreme' OC scenario. As far as the Ivy CPU's are concerned, not all that impressed. With two, the best they will do is 51X on one and 52X on the other using conventional cooling.
 
Hey man, do these glow (LED's installed)  right out of the box, or do you have to add them in? I can't seem to find a definitive answer on google. Corsair says it supports customized LED's coming in September, but the picture on their site shows it glowing blue...
 
The LED's are white and work as advertised right from the package with nothing special required. Plug them in the DIMM slots and that's it. :biggthumbsup:

Ohh white, they look blueish in the picture on the site. :D

Thanks for the reply, going to order these tomorrow!
 
This September, they are going to offer other color LED's so it is possible to replace the white that come as standard. Most likely at least green, blue, or red.

As a side note, these worked great on MSI's P67A-GD65(B3), Z68A-GD80(G3), Z77A-GD80, and the X79's. I just noticed today they now offer a 32GB 2133 @ 1.50v kit. Wow! With even higher speed RAM to come. :-)) Now if only the CPU IMC's will be able to handle it. We shall see.
 
I am afraid CPU IMC's will lag behind until the next generation.
And from an article not too long ago, it was apparant that the bigger the gap between native IMC support and the RAM frequency, the less benefit. In fact, peformance starts deteriorating after a certain point.
With Sandy the upper end seems 2133 and with Ivy at around 2400 although within the article it was mentioned that they experienced a reduction in FPS in gaming at 2400 whilst testing with an Ivy.
 
I don't want to take the thread too far off topic, but until recently, I didn't know an Ivy 22nm CPU was needed to get over 2200 RAM speed on some MSI mainboards. I have had some Corsair CMGTX3 2400's sitting around for a long time and always wondered how come they never would go past 2200 and now I know. So, with a Z77 and an Ivy in it, I was finally able to get them to 2400 speed. The results were decent, but not a lot of improvement over 2133. Not enough to justify the 1.648v's it takes to power them. ;)

In fact, peformance starts deteriorating after a certain point.

I've seen that as well.

Added: They OC over the already 2133 'rated' speed easily with only changing the DRAM Frequency from 2133 to 2200 without making any other changes. :biggthumbsup:

Just got my sticks in the mail yesterday! http://www.corsair.com/en/memory-by-product-family/dominator-platinum-ddr3-memory/dominator-platinum-with-corsair-link-connector-1-5v-8-gb-dual-channel-ddr3-memory-kit-cmd8gx3m2a2133c9.html

Posted right up @2133 with no problems! Got them down to 1T-9-10-10-21 with no voltage tweaking, prime95 testing now (blend 6 hours so far).

Happy with them!

:biggthumbsup: Nice! Able to tweak the tRFC a little tighter as well?

I've actually never messed with any of the RAM timings below tRAS in the BIOS... :D  Currently the BIOS says tRFC is running at 171, but that seems a bit high! I'll look up more about this tomorrow when I wake up, but in the meantime do you have some advise as to what tRFC I should start with these sticks?

Also, is there any point in tweaking any of the other timings? I would assume not... might as well ask! :p
 
tRFC 171 is correct. I don't mess with any setting below that one. It seems high, but not so bad when compared with some. One kit of 2000 GT's I have need a tRFC of 200, so the myth of fast RAM speed once again comes to light. It may be reading 2000 RAM speed, but the timings and voltage to make it work, barely if at all, beat 1600 with low voltage and tight timings. Only way to verify these performance results is of course through testing and running the numbers for comparison.

Doing some quick reading online about other RAM kits at 2133, I dropped the tRFC down to 125, prime 95 has been running for 3 hours so far. So I guess this kit is just a beast with tightening up timings? Almost seems too good to be true! :D
 
125 if sick, I have corsair vengence and have it a 9-10-10-24 1T
I still have my RFC at 161, I don't think I'll be able to get it under 150ish.

Interesting... that is quite a big difference! This is kind of a stupid question I feel, but i'm assuming setting tRFC too low would cause BSOD's in prime 95 just like the other timings, correct?

:shocked_anim:  tRFC 125? And stable?

Yes, that is true. Too low a tRFC can cause BSOD just like other timing settings can.

So I guess this kit is just a beast with tightening up timings? Almost seems too good to be true!

I don't know what to say! Stability tests and actual daily use without any problems can't be disputed. I will see if I can match your tweaks. Each individual system reacts different, so your results may not be typical, but wow! You got a good thing going there! :biggthumbsup:

Added: It will be interesting to see if it is possible for me to achieve your result with 2 unmatched batch kits.
 
Going on almost 5 hours prime 95 on blend... seems good at tRFC 125!

EDIT: tRFC at 80 would not POST, but 90 did! Giving prime 95 a go and will report back.

Also, leaving the RAM voltage on "Auto" in the BIOS, with XMP enabled is okay, right? I saw it reporting 1.497v or something like that in the BIOS...
 
Try intel burn test, see if it will survive that on maximum with that rfc.

I too will try to match this with regular vengence and a sb cpu. (Fat chancel lol)

If it works, it should be fine. I'm still in a bit of shock at your results!
