Hello, everyone! I am new here but I have a big headache. I just bought an expensive Intel P3700 NVME PCIE SSD (>1300 US Dollars, not the old SATA Intel S3700 SSD model), it is really a beast as per different review articles from the Internet. (3000MB/s read, 2000MB/s write for 800GB or larger model)
However, I found the compatibility issue with my M7H board, for those ROG users who are considering getting one of this beast, they have to think twice:
My original configuration:
CPU: Intel 4790K;
MB: Asus M7H, BIOS 1104 (Latest);
Ram: Kingston HyperX Beast 2400 DDR3 8GB x2, (XMP Profile 1 = 2400MHz, XMP Profile 2 = 2133 MHz);
VGA: Nvdia GTX 780 ti;
HD: WD Re 4 2TB;
PSU: Cooler Master V1000 1000W;
CPU Cooler: Corsair H100i;
The description of my problem:
(A) Initially I had my 8GB x 2 ram in slot 2 & 4, XMP set to Profile 1, everything works fine, no 2nd/3rd boot/boot loop, nothing unusual;
(B) Then I installed the P3700, I could enter the OS (ram slot 2 & 4), and I could also install windows 8.1 in the new P3700, but then I found that I only get 8GB ram, which means another 8GB ram is missing;
(C) Still my ram is in slot 2 & 4, I tried to enter BIOS, but couldn't. When I pressed "DEL" I got dark screen only and ASUS Q Code = D5, which means "no space for legacy option rom";
(D) I unplugged my SSD, everything fine again;
(E) Then I tried to used slot 1 & 3 for my ram, the computer couldn't even boot, this time Q Code = 55, which means "Memory not installed";
(F) I then tried my ram into slot 1 & 2, for this time, i can enter BIOS, i can enter OS, i merely don't have dual channel ram, which was understandable and acceptable to me;
(G) However, in this case, I experienced 2nd / 3rd boot, the system will boot for twice or 3 times, no matter I boot for both cold boot or restart boot, when makes me feel worried;
(H) I changed XMP to profile 2 (2133MHz), or I also tried switching off the XMP, then I could boot without problem, no 2nd / 3rd boot.
So in conclusion, now i could only use 2 x 8GB Ram in 2133 MHz and single channel plus my Intel P3700 SSD, or i could choose to use my ram in 2400 MHz and dual channel, but without my new and expensive SSD, which drives me crazy...
And i have searched a lot through the Internet already, and I found this link from another ASUS forum:
"
http://vip.asus.com/forum/view.aspx?board_id=1&model=MAXIMUS+VI+EXTREME&id=20140704075147174&page=1&...", in which other ASUS users described the similar problem of the Intel p3700 SSD with ASUS MBs as I described in item (C);
I wonder if some one could advise a solution, so that I could use my P3700 SSD together with my ram in dual channel, 2400MHz??
I don't think it is an easy to answer question, and I have tried doing all things i could think of such as trying another ram or clearing the CMOS.I understand my problem is complicated when it consists of several issues, much much appreciate if sb can advise sth which makes my config better then their current situation...Anyway I don't wish to find that the P3700 SSD is a waste of money, or a big problem to ROG board users.
Thanks a lot!!
