best Speed vs Latency for DDR3

post #1 of 9
Thread Starter 
Using the last Generation of CPU to use DDR3, it should be the best at running ddr3, and indeed it is. I already tried to overclock some 1600 trident sticks, but its true. the PCB matters. The 1600 sticks were made with inferior PCB to the higher clocked sticks.

I Can run my 16GB RAM at the rated DDR3 G.Skill Trident Speeds, of 1866, 2133, and 2400. Now the timings are all 1 cas from each other.

Want to know the best and fastest for gaming, and how latency effects online gaming.

1866 Mhz 8-9-9-24 2T 1.5V


2133 Mhz 9-10-10-24 2T 1.6V

or

2400 Mhz 10-11-11-31 2T 1.65V


I am sure the 2400 Mhz is the fastest and best for gaming, but wanted your opinion.


I was able to mix and match 2 sets of 16GB DDR3 ram and manual set the timings, and it did work in windows at 32GB. I took them out though, since it was making the RAM temps higher, and 32GB was not being utilized. After I took them out, to back to 16GB, windows would not boot anymore, expecting 32GB. So I had to put them back then, do an earlier system restore, shut down, then take the other 16GB out, then I had to do another system restore. just FYI. Make 2 backups if you plan to mix and match ram.

Sincerely,
Technodox

That's the fastest. I'd stick with this. Faster ram helps the system feel snappier in everyday tasks, gets your minimum FPS up a little in games.

Test it for yourself using firestrike's api feature test, see which settings give you the most draw calls.

I did, and am not sure what the draw calls are, or can be found. The most significant increase in score is from the GPU, and second CPU

This is all correct. As if you needed confirmation lol. But more for the OP.

It's a separate benchmark from firestrike. I'd run it 5 times and kick out the high and low scores averaging the remaining 3 for each ram setup. I don't think you'll find much advantage going above 16 gb for gaming just yet fwiw.

These are all valid and tested good timings which are faster and less than the xmp timings.

1866 Mhz 8-9-9-24 2T tRFC 174 1.55V


2133 Mhz 9-10-10-24 2T tRFC 174 1.6125V

2400 Mhz 10-11-11-31 2T tRFC 193 1.65V +some SA, D/IO, A/IO

OrkinMan,

I dont own the full version of 3DMark, so I am unable to run the API overhead test.

2400 will provided the most bandwidth but latency is most important
run aida64 to see which provides the lowest latency im betting it will also be 2400 making it the clear winner if that's the case
the difference between 2133c9 and 2400c10 is small and would be hard to measure with anything but synthetics but the gap to 1866 would be measurable in a cpu limited section of open world game
