64GB at 2400 is all I want, but it's fighting me.

I am on a journey to get this RAM to run at its rated speed (2400) with all 64GB installed and failing miserably. With everything at Optimized Defaults, the RAM, with all 64 installed, will pass SuperPi 32M, run through Memtest86 error free, 400% HCI Memtest, and consistently boot into the OS.

With XMP enabled, or a manual input of the speed and timings, it will still pass SuperPi 32M, but booting into the OS becomes sporadic (code 79 and 60 spring to mind, can’t remember the others), Memtest86 throws out errors aplenty, and HCI Memtest BSODs after some time, never getting close to 400%.

I understand that populating all 8 DIMMs requires more power and have attempted to up the DIMM voltage to 1.35 from 1.20, as well as upping the SAV, though, I didn’t go that high with it (0.90), as I felt at just 2400, it shouldn’t require that much power, but this isn’t at all my area of expertise.

I’ve read thread after thread, but don’t seem to be gaining any ground.

This is my first attempt to exceed 32GB, and well, I need some help. I just want it to run at its rated speed, nothing more.

I bought a Corsair Obsidian 750D last year ... foolishly and naively thinking that every case in the Obsidian line would use interchangeable parts. Not all parts, of course, but many of the various panels and drive bays and such - I even assumed Corsair would cheap out by trying to fluff out identical components into a whole family of variants. Not so. The only interchangeable out-of-the-box component is the screws. I had a helluva time just trying to get a simple no-window panel, lol.

I wish more companies went modular. Enterprise stuff has been maximally interchangeable for years (provided you buy from one source, at least, like Dell or SuperMicro). I hope Caselabs proves a winner in this.

Well, I got a good 3 weeks of stability out of it. What passed every stress test I threw at it has decided to call in sick.

It started when the mouse began to freeze while reading a website. I just knew it was about to go downhill from there. Sure enough, the computer froze with a VIDEO_TDR_FAILURE BSOD. Upon reboot I got the overclock failed message. Coming out of the BIOS it locked up at code 90. Another reboot locked up at code d6. Yet another reboot and code 6F. Lastly a code A2. Good times!!

This board has certainly been a tester of m patience.

To pass stress tests left and right then all of the sudden give up after 3 weeks is just frustrating to say the least. Back to the drawing board, I suppose, of finding that elusive stability.

I am sooo not OC'ing my MOBO until I absolutely have to to keep up with the ever-increasing computing power that the gaming industry requires to play its games as time goes by.

Sounds like a conspiracy to me. . ..

Ha!

Out of all of the boards I have OC'd through the years, this one is proving to be the most frustrating. Even though I left my OC at what I would consider extremely mild (4.2 on the cpu, and the 2400 the RAM is rated for), it is still an OC, and at this level, I understand that it can sometimes be a dance to get it right. It's still frustrating.

Just like sports cars and sports bikes, which I also very much enjoy pushing past stock, you may get lucky and find the perfect combination of parts, or end up chasing a solution to what should seemingly work right away. but just doesn't, no matter how right everything seems.

Now with all of that just said, the board has truly gone back to its unusual ways. I have everything back to stock currenty. The thing is, it will no longer boot into Windows unless I force boot the drive it is on. Not to mentioned a constant dance between codes A2 and 98 while attempting to just get to the BIOS. This is with a cleared CMOS as well. None of it makes any sense.

Alright, back to it to try and figure this all out. I welcome any insight.

Not from me, for I have yet to fire mine up for the first time. I am currently just kind of freaking out on all the horror stories I am reading.

Oh come on, dive in the water with us. 😛
