Hello,
I'd like to buy MB Rampage IV Black Ed. with CPU i7-4960X. I'd like to install 2xSSD Samsung Pro 840 256Go in Raid 0.
My first question is: is it now possible to run Trim with Raid 0 for this MB? Intel told me that Trim is not supported on X79 series, but I read some posts about modded bios. Is it possible today to have Trim with Raid 0 on Black Edition without modded bios? If yes, which bios version and which Intel RST version?
I read the guide about Win8 UEFI Installation but Intel told me that the x79 MB doesn't support Trim in Raid 0, even when I told that I'll install the RST 12.8.0.1016. Did someone test Trim with Raid on Rampage IV Black Ed. with Intel Rst drivers? What about the Bios of Rampage IV BE? Does it allow the Trim for Raid? Which Bios version? I don't want to have doubt about Trim with Raid 0. Could you help me?
And how to verify that Trim are working? Is still the HxD - Freeware good to test Trim under Win8.1? Sorry, but I'm newbie about new configuration. I only know Raid on HDD and on older motherboard.
My new config. will be on Win 8.1 64bits:
- Rampage IV Black Ed.
- CPU i7-4960X
- 2xSSD Samsung Pro 840 256Go in Raid 0.
- ASUS GTX780TI-DC2OC-3GD5
- GSKILL Ripjaws Z 32 GB or 64 GB. I need advices to help me to choose best models for stability.
- 2 x Seagate Barracuda 7200.14 SATA 6Gb/s 2 To for stockage
- AX1200i Corsair
- Cooler Master Cosmos II
- Corsair Hydro Series H110
I really want to be sure that Trim are working for raid on this MB because it's very expensive and I don't want to have problem.

I have a second question about RAM for best compatibility and stability with my MB and CPU: I need advices for GSKILL Ripjaws Z 32 GB and 64 GB models. GSKILL told me than for 64 GB, it would be better to choose 2133Mhz , not 2400Mhz, but didn't give me references. On the website, Asus listed the GSKILL F3-17000CL11Q2-64GBZLD(XMP) ( 8x 8GB ). On one post, I found this adviced model GSKILL F3-2133C9Q2-64GZH. It's not the same CAS. What is the best for my MB and CPU?
For 32GB capacity, GSKILL listed RipjawsZ F3-2400C11Q-32GZM 32GB (8GBx4). What do you think about this?
Thanks for your help.

Hello,
Thanks for the response. Which are the appropriate Intel Raid drivers? Asus list the Intel RST 12.8.0.1016. Are they good for Trim Raid 0? Need I other "modded drivers"? What's the way to do a clean install with trim raid 0? Perhaps can Rampage IV BE's users help me to have a clear idea to do a correct install. Thanks in advance!

Hello, many thanks Fernando for your help. I read a guide to install Intel RST drivers on X79 and it was written to only install OS in UEFI Mode with GPT partitions. Is it still necessary ?

Hi, I just bought the Rampage BE and have the GSkill rip jaws Z at 2133 mhz. However, the intel CPU will only accept 1866 Mhz so the rest is a waste of money. my cpu is i7 4930K and that is the RAM freq range. Check with intel specs on the cpu of your choice and see what freq is the max ram it can take. On the 64 or 32 GB question, 32GB is more than you need and you can have a fast RamDisk too with memory to spare. the more ram you hove the longer the bios takes to check it and the boot is longer.
My problem is I have 4 samsung 250GB EVO SSD's and trying to configure it for RAID10, I gave up and now I am trying for Raid 0 (1 TB). I can't get my data HDD installed with the SSD. Rampage BE has 2 HDD controllers (Intel and Asmedia). I put the HDD on the Asmedia and the RAID0 on the intel but when running Norton, my system crashes constantly. the RST is ver. 12.9.0.1001 and the bios version is 12.7.0.1936. Work in progress and experimenting.... 5 days now.

In that case maybe you got a "weak" CPU or chipset. I have G.Skill 2400 MHz and used an I7 3930K before which supports 1600 MHz max per specs. But my RAM ran fine at 2133. Now with the I7 4930K I can even use the first XMP profile and the RAM is at 2400 MHz CL9 (!).
All this on mainstream ASRock X79...

EDIT: But it's not Ripjaws but Trident-X memory, maybe that also helped.

Maybe you can help me.
My system is Rampage IV BE, 32 GB G Skill rip jaws Z 2133, 4 Samsung EVO 250 GB, and 3 HDD (1.0, 1.0,2.0TB) Green WD, all water cooled with EK, full MB block, ASUS R9-280X Matrix P water-cooled all running Windows 7 64 bit Ultimate.
I cannot get my SSD to co-exist with the HDD's, crashes every time I bring up explorer to look the the hard dirves,
any experience?
I installed the SSD drivers before windows is installed and install the app for windows (RST). both have the same version 12.9.0.1001 and the bios RST ios 12.7.0.1936.
If I install just the SSD, all works fine.
P.S. my Ram can run at 2133 but the cpu specs show 1866 on all i7 socket 2011 cpu's at the inlet website but prefer to run them at the spec 1866. could have saved money and bought the 1866 version. And, ASUS did recommend this brand too as tested.
Running X.M.P. mode profile #1 for the ram but reduced the freq below in the bios

@inlandchris

As I had the same problem before with my ASMedia connector I recommend to either use the very latest driver (2.0.4.1 I think) you can find on station-drivers.com or downgrade to the MS standart driver for your 106x ports. This should solve your problem.

Good luck hanson


EDIT: Regarding your RAM. as long as your system does not freeze there's no danger in letting the RAM run at 2133 MHz. The 1866 MHz Intel spec only says that this speed is 100% supported. When you run your RAM faster and it works you don't overclock your CPU at that time but just run the RAM at it's desired speed.

@inlandchris

Sorry the latest ASMedia 106x driver is 2.0.8.1 released 14.03.2014

Thanks all for your help, still major problems. Just got an email from ASUS support, absolutely no help, your forum is much better! If I take my mobo in, it will be months before I see it back.
My system is crashing now even before I put my password in, like before.
Once, I installed the os on just the SSD with no other HDD in the system. Then, I plugged in 1 HDD and started the system and it blew away my OS installation, another wasted time.
Now, I am getting BSOD with either IRQ not equal or less than, and win32.sys as the error. Getting tired...
