Well, why is ram so important;
since we have fast CPUs and GPUs many players have already mentioned that the simspeed is low even when their CPUs/GPUs are only running with 30% load.
So there must be another bottleneck that causes the low simspeed.
So i started some RAM testing to see if maybe the RAM is causing the low simspeed.
I have 5 PCs here for testing; i7-4790K, i7-6700K, Ryzon 5, and 2x intel Core2 Quad @ 2.5 and 2.6 Ghz.
I increased or decreased first the CPU clock with almost no effect on the simspeed.
Even when i decrease the CPU clock from 4Ghz down to 1.8 Ghz, the simspeed still does not go slower.
Then i tested the GPU. There was no effect at all.
Last i tested RAM speed.
Effect: if you decrease the RAM clock then also the simspeed is going slower. And in case you increase RAM speed then also the simspeed is faster.
I did some additional checks with diferent RAS-to-CAS delay, CAS latency and Row Precharge and Cycle Times.
When you buy RAM modules you will see numbers like "CL8 8-8-24"
That means:
CL8 = CAS Latency
8 = RAS to CAS delay.
8 = RAS precharge
24 = active to precharge Delay
(If you buy RAM; lower numbers are better!)
Most important is here 24 = active to precharge delay.
This is the time a RAM needs to internally refresh the row where we have written the last data.
Also important, use RAM that are doublesided. (mostly they have momorychips on both sides of the memory module)
And try to use a mainboard that can use memory in quadchannel, at least dualchannel.
I am telling this since 2 years here, but no one cares ^^
