Hello to fellow rog enthusiasts.
For TL;DR (Too long ; Don't read) jump to last paragraph. Thanks in advance
Seeing how ram bandwidth really drives performance on some games and other latency sensitive application i was thinking what would be the optimal decision to make regarding ram purchase.
I have currently ordered a Gskill F4-3200C14Q-32GTZR ram which as its name suggest is a 4X8 GB RGB kit from gskill rated for 3200 Mhz for intel platform.
I know AMD does not support officially support that kind of speed for 4 dimm single ranked modules but a lot seem to have managed to reach those speed with various BIOS by overclocking.
Demand for kits at 3200 Mhz has been very high and its very hard to find them is stock. I am considering dropping the ram i currently have ordered and getting higher rated kits at 3600 Mhz or even 3866 Mhz (for intel platforms) which are in stock
Instead of waiting for the F4-3200C14Q-32GTZR
https://www.gskill.com/en/product/f4-3200c14q-32gtzrto arrive I am specifically eyeing the following (yea i am in love with the looks for this line of RBG) since those even though more expensive are in stock:
- F4-3600C17Q-32GTZR
https://www.gskill.com/en/product/f4-3600c17q-32gtzr- F4-3600C16Q-32GTZR
https://www.gskill.com/en/product/f4-3600c16q-32gtzr- F4-3866C18Q-32GTZR
https://www.gskill.com/en/product/f4-3866c18q-32gtzrFrom what i gathered all those kits must be Samsung B die chips inside. Best memory manufacturinng process or ram atm. Is that assumption correct? Any chance any of those have the undredly hynix ones?
I know getting above 3200 mhz is pretty much a wet dream now and probably in the near future with a Ryzen 7 1800X and a 370X chipset but my train of thought is that the next iteration of ryzen should also run on the crosshair VI hero and most likely will be made on a better and more mature manufacturing process. This process then should support better speeds.
Some reading of the crosshair VI hero overclocking thread of overclock.net i found some intresting data.
http://www.overclock.net/t/1624603/rog-crosshair-vi-overclocking-threadBoth the ram i ordered F4-3200C14Q-32GTZR and the F4-3866C18Q-32GTZR have managed to get 3200 Mhz stable with 32 GB.
The F4-3866C18Q-32GTZR has managed to do so with slight higher voltage. Then again this might be due to varition of the IC in memory controller
DIMM Part number DRAM IC DRAM Configuration BCLK Frequency DRAM Ratio DRAM Frequency Timings Voltage CPU SOC Voltage BIOS version
F4-3200C14Q-32GTZR Samsung B 4x8GB 100 3200 3200 MHz 18-16-16-38-75-2T 1.35 1.1 Bios:0083
F4-3866C18Q-32GTZR Samsung B 4x8GB 100 3200 3200 MHz 18-16-16-38-2T 1.4 1.15 0902
My understanding is the 3866 Mhz kits since is better ic ram can run at 3200 14-14-14-36-2T but the F4-3200C14Q-32GTZR most likely wont be able to reach 3866 at the more loose timing of 18-19-19-39-2N unless you are really lucky. Ryzen 7 seems to care more about speed than timings.
Should i get the more expensive but faster in stock F4-3866C18Q-32GTZR kit or wait for the out of stock F4-3200C14Q-32GTZR but cheaper kit to increases chances of getting 3200Mhz with 32GB(regarless platform considered)? Maybe the F4-3600C17Q-32GTZR or F4-3600C16Q-32GTZR.
Thanks in advance.
