Tri-Channel DDR3 3x8gb Ram?

Recommended Posts

Posted · Original PosterOP

Just wondering if anyone has ever seen DDR3 1600MHz memory/ram in 3x8gb (24gb total) configuration for a tri-channel X58 motherboard?

Yes, queue the nostalgia:

 

Edit: Wait nevermind, that's 6x4GB. But still, oh the nostalgia

8GB DIMMs were very rare to my knowledge back in the X58 days, at least on the consumer side, so I think it's a combination of 8GB sticks not being available at the time and most X58 boards not even supporting them because they were so unpopular or maybe even nonexistant.

I mean, I've done it with three sticks of the same RAM, with certain sticks you can even get 6x8 GB. 1600 MT/s is easily achievable, but not much beyond that, I was running into an inability to set the higher latencies needed for high speed DDR3.


Main: AMD Ryzen 7 1700X, Nvidia GTX 780, 16 GB 3000 MT/s DDR4 Fedora 32 x86_64

Secondary: Intel Xeon X5670, Nvidia GTX 660, 24 GB 1333 MT/s DDR3 Windows 10 Home x86_64

Server: Intel Xeon X5670, 60 GB 1333 MT/s DDR3-R Ubuntu Server 20.04.1 LTS x86_64

Laptop: Intel Core i5-3320M, 16 GB 1600 MT/s DDR3 Fedora 32 x86_64

In theory you can run 288GB per socket on LGA 1366 xeons... 32GB RDIMMS, 3 per channel on server boards. You won't be getting top-of-the-line speeds though.

 

SOLVED] Is it better to have many small or fewer large RAM sticks ...

I guess it might help to clarify my question about the ram. If you've seen my post of my desktop PC or profile, I have a Dell XPS 730X running a X58 Alienware Aurora ALX R1 series motherboard. I use the hybrid Alienware BIOS cross flash developed by Eric Duncan to make the motherboard compatible with the 730x MCB and other components, https://en.wikipedia.org/wiki/Dell_XPS_730x . The 730X originally maxed out at 12gb @1600MHz of memory, but with the hybrid BIOS cross flash is now capable of operating with 24gb of Tri-channel. All in all, buying four sticks and just using three is not out of the question, just curious about my original question.
