*Official* Intel DDR4 24/7 Memory Stability Thread - Page 155

post #1541 of 6327
By the way it shows it is quite impossible to estimate That an overclock is stable...
Look, 11h30 HCI test and crash !
And this thread is a stability thread With only 500% coverage for 16GB.... smile.gif

With the X99 is it ok to use 2 ram kits? Same brand, speed and timings. Id rather one kit but would 2 kits play nicely?

Hello

Been this way forever. And you are using the wrong type of memory for the length of memory testing you are doing.

Quad channel kits are backed by the warranty that all 4 DIMMs working together will operate at the stated speed or you get a replacement/money back.

If you get 2 dual channel kits and try to run them in quad channel, you are operating them outside the manufacturer's specs, even if you run them at the stated speeds. So you cannot get refund/replacement if they don't work in quad channel. Also, the programmed in timings may only work in dual channel configuration.

Nothing preventing you from doing it anyways, but you won't get manufacturer support on it. There's no guarantee you will get stated speed or better by using 2 dual channel kits in quad channel. Probably won't get much help here other than "try lower speed" or "more voltage" or "looser timings" or "tweak this n that"

And all went very well during 11h30 and then, SPLASSH => My computer rebooted !!!

What should I do as modified timings to get 12 hours stability ?

Test one overclock at a time. RAM at OC speeds, CPU/cache stock. CPU at OC speeds, RAM/cache at stock. Cache at OC speeds, CPU/RAM stock. Then start combining until you get all 3 stable.

I see. I was thinking more along the lines of 2 quad channel kits together making it 8 modules in quad.

Thats even worse. Good luck. There is probably a reason why manufacturers dont make 3600mhz 8 dimm kits, the cpu cant handle it.

Lol okay then ill stick to a single kit. Thanks for the input.

Edit: oh no i was shooting for 2666 on 8 dimm.

CPU and cache have already Been tested since à Long Time.
I am now taking care of RAM since some days
