RAM suggestion

[beastintheeast]

Hi. I am attempting to build my first pc in the upcoming month or two and i was curious about RAM. To sum it up, CAS latency vs clock frequency. Would it be better to buy 2x8gb (maybe 16gb but size isnt the main issue) with a CAS latency 14 and 3200mhz or 2x8gb with CAS latency of 16 and 4133mhz? Both are about the same price but im not sure what the advantages latency has over clock speed or vice versa. Help would be greatly appreciated.

 

Thanks

CL14 3200 MHz is going to be more plug-and-play than CL16 4133 MHz.

They affect bandwidth and overall latency. Bandwidth is largely based on frequency (though looser timings can also make it worse), while latency can be estimated by frequency divided by CAS latency. What CPU is this going to be paired with?

What 4133 C16 kit is that?

im fine with testing and all that. I had to do alot of work on my current pc to get the ram to run at 3200mhz. Not sure what the problem was, eventually it just worked instead of black screening

Did XMP/DOCP not work?

sorry i was a bit wrong with the latency on the 4133mhz ram, most cl18 or cl19. but i found a kit with 4000mhz and cl16. all the ram ive been looking at is made by g skill.  F4-4000C16D-16GTZR  its about 30 to 40 dollars more but im fine with that. i just cant afford a 4800mhz kit. 180 is probably my limit for ram.

No, not at first. whenever i would enable it wouldnt post or it would run and the motherboard would cycle through post codes but the screen would stay black. I tried manually setting voltages. I saw a thread about running 1 stick at a time, so i tried that and both sticks would work, just not together. Eventually it just worked though, im a little baffled but at least its good now.

do you think that 4000mhz cl16  or something like F4-3600C14D-16GTZNB would be better?

4000C16 is a good place to start. Thing is there's only.so much bandwidth you need, but lower latency ia always better. I suggewt tuning down timings at 4000MHz.
