Ram upgrade

1 : Anonymous2021/11/29 00:44 ID: r4j1cu

I have 5800x on a asus strix b550-a motherboard. i have a 2x8 corsair vengeance ddr4 3600 and i wanted to know will there be any issues if i buy another 2 sticks of the same ram?

The problem with Corsair is (assuming it's a CL18 bin) they change IC's in those kits on a weekly basis since just about any modern IC can do 3600 CL18. So there's no guarantee of compatibility.

Asus is not t-top since 300-series boards.

iirc, the memory controller having trouble when you trying to OC a 4x8 ram. Please do correct me if I am mistaken.

It is harder to run therefore you will reach lower max frequency on the RAM. But that is not a big issue on ryzen because you want to Land inbetween 3600 and 4000 anyways.

But the board might be an issue. The b550 strix has a memory layout wich causes problems trying to run 4x8gb. Buildzoid tested that on a b550 strix XE and i had the same issues on my b550 strix-f. You Hit a wall at around 3800 mhz when running 4x8. I could do 3800cl14 but going 3866 i could not even get cl18 stable. ( not a fclk issue here , i tested that independent)

Also you want to check if corsiar changed the used IC's in the time between the purchase. You dont want to Mix IC's if possible

Maybe not relevant, but I went from 16GB (2x8) 3600CL15 (F4-3600C15D-16GTZ) Single Rank B-dies to 32GB (2x16) 3600CL16 (F4-3600C16D-32GTZN) Dual Rank B-dies.

Running almost the same manual 3800CL15 tuning on both kits, the only big difference is that I struggle running the 32GB kit with GDM OFF, resulting in tCL16. The end result is within margin of error so cant complain. Curious to how another 16GB, 2x8 to the first kit would behave.

Havent really tried going beyond this tuning since temperature starts becoming an issue and I doubt its worth all the extra work for probably little gains.

I added 4 - 8 gig sticks of Crucial Ballistix RGB 3600 MHz to my ROG strix b550-a with no problem but i am not tweaking the ram or cpu basically stock set up.

The reason i added the extra 2 sticks was i wanted to play around with ram cache.

If you are tweaking timings and stuff like that you may not get the most out of your ram but it should work with no problems at stock settings.

The only notable difference would happen if you are exhausting your memory, which is unlikely.

Basically, 16Gb of RAM is good for most and DDR4-3600 is quite fast, so if you're looking for a performance uplift look at your storage first.

Does HDD effect performance?

Absolutely! An SSD is the biggest upgrade anyone can make if they're still using a mechanical hard drive.
