how much difference does faster ram make?

[Mahbub]

i have i5 8600k and gigabyte z370m d3h mobo, now i have heard the highest that i5 8600k supports is 2666 mhz ram. right now i have corsair vengeance 2400mhz 16 gb ram, i am thinking to replace it with corsair vengeance 3200 mhz 16 gb ram, what difference will that make? will it underclock to 2666? if so can i oc it to 3200 (which technically fot the ram wont be oc) and how much performance difference will i see?

who in the hell told you that? that's the base frequency or the highest supported before it's technically an overclock to the imc.

99% it will work.

[Chris Pratt]

Anything over 2666 is an overclock. Speeds like 3200 are XMP (eXtreme Memory Profile), which is literally an approved clock and timings to overclock with. There should be no issue enabling XMP for your setup.

 

The RAM will definitely be faster, but how noticeable that will be depends on your usage. This isn't something like going from HDD to SSD or an iGPU to a 2080. In very memory intensive tasks you'll probably see a noticeable improvement, but largely it probably won't make a huge difference in your system performance. There's just not a big enough jump here.

Ok someone told me on z series boards i5 8600k will run ram at even 3200.. on youtube game results m seeing big fps jumps on this cpu from 2400 mhz to 3200.. so m thinking to change ram.. also if i buy 3200 mhz. Will it be safe to run at 3200 mhz? Will there be any risk to the mobo or cpu?

M seeing quite big fps jumps in games on this cpu in youtube vdos with faster ram.. but i am afraid .. if i buy 3200 mhz and run xmp and run ram at 3200 will the mobo n cpu be safe? Also can i buy even fastee ram like 3600 or 4200? And pair it with this cpu? Is that safe?

unless you put the vccio/vccsa to insane voltages and the dram voltage to insane voltages no.

ok i just came to know that my mobo, gigabyte z370m d3h supports ram upto 4000mhz, so if i get a 4000 mhz ram and put it in and enable xmp, will it run at 4000? i dont wanna tweak volts or anyting, thats why m buying faster ram so i dont have to tweak volts, or else i could just oc my existing ram to 3000, so please tell me if i buy 4000 mhz and enable xmp will it automatically run at 4000? and will it be safe? i do not wanna tweak any volts/..

might and might not. depends on what the imc can handle.

could and could not, though you might have to tweak vccio and vccsa voltages and dram voltages.

whats imc? my mobo specs say it can handle upto 4000

4. Support for ECC Un-buffered DIMM 1Rx8/2Rx8 memory modules (operate in non-ECC mode)
5. Support for non-ECC Un-buffered DIMM 1Rx8/2Rx8/1Rx16 memory modules
6. Support for Extreme Memory Profile (XMP) memory modules

 

whats vccio and vccsa, i am a noob at ram

 

lastly if its safe to tweak volts and run at 4000 then m going for 4000 ram...

if it's reasonable then yes. anything 3600 wont really bring more performance especially for intel.

a lot of things but it basically improves imc s in this case.

ur mobo likely cannot handle 4000, despite what it says on the specs, 3600 or 3866 is the highest i'd push it, io and sa is for ram oc, 3600 might need 1.1v is recommended just for booting, 1.2v might be required for 3600/3866, 1.25v might be required for ddr4000, again that depends on ur mobo, for ur particular mobo and ur situation i recommend 3600.

well i can go with 4000 anf just downclock to 3600.. cant the mobo handle 1.35v?

1.35v io/sa is not recommended for long term use, it's pointless.

for the vccio and vccsa? technically yes though dont go over 1.2.

Here i overclocked my 2400 ram to 3000 now its using 1.36v..  does this mean if i buy ram which by default is over 3000mhz, it wont run over 3000 below 1.35v?

dont trust them lol. just dont go over 1.2, and every imc has different capabilities, it also depends on the IC's that are being used for the ram.

no, this kit is not rated at such frequency so it will need more work to get to it, the 3200 kit is rated for 3200.

okk then m gonna go for 4000.. if need be i will run at 3600.. today after seeing videos m surprised at some games having big jump in fps going from 2400 to 3200

Z motherboard, generally speaking as long as the CPUs memory controller is decent it will run any memory you put in it within reason.

 

The memory speeds listed by Intel are just what they are specified for, and on locked motherboards, what it will run at maximum.

 

Your memory should run at 3200mhz no problem.

thanks.. well i rechecked and saw my mobo supports upto 4000, now m planning to buy 4000 mhz memory

Most you should buy is 3600. After that performance hits a wall, the cost becomes prohibitive, and your IMC may not even like it at the top end.

 

3200-3600 is pretty much the sweet spot.

well i can just downclock it to 3600, future proofing, also if it runs at 4000 is there any danger... also another question...

 

i have two options 1) thermaltake toughram with tested latency of 19-23-23-42

                                2) G.Skill Ripjaws with tested latency of 18-22-22

                                 which is better at latency?

1. By the time you upgrade, you'll probably want DDR5 anyway.

2. No danger, it will only run at the maximum your CPU can support. Coffeelake IMC is pretty good, so it will probably work. But even if it does, you won't be that big a deal.

3. Lower latency is better.

 

Review this before you buy:

 

 

3200-3600 is the most reasonable memory to buy.

i am getting 4000 mhz for good rate so going for it,, and i am a total noob at latency stuff can u just tell me which one of these two have lower latency
