Thank you for the explanation. What I don't understand though is how 2000*(cl/Mhz)=ns is wrong though. It allows you to generally compare two rams which advertise different speeds and latencies. That seems practical because until you buy them, what other way do you have of comparing apples to oranges. What you are describing if Im understanding you, is that the ram MAY be faster after you get it home in your machine and put it to use.

 

Right now I am using G.Skill Trident 2400 cl 9. Do you believe I would notice a diffence in fsx if I switched to 2600 cl 10?

 

2000*(cl/mhz) doesn't give you raw latency, it only applies to one aspect of memory access as there are numerous other latencies. You can read about it here: http://en.wikipedia....iki/CAS_latency

 

Also keep in mind that latency alone is not the only relevant performance metric when it comes to memory performance. Bandwidth is equally important for many applications, FSX included (as evidenced by the FSXMark 11 performance results).

Thanks for the insight. I have an Asus z68 motherboard that only supports ram up to 2200 MHz. I have already overclocked my i5 2500k to 3.7 ghz. Can you recommend some affordable ram? Thanks.

With Sandy Bridge and Z68 you're already at or near the limit of RAM speed your platform can handle/take advantage of. If you want more memory performance you'd have to go with Ivy Bridge and Z77, I'm afraid. That and overclock your CPU muck more, at least another GHz. You would gain far more performance from the OC itself rather than the increase in memory speed, but it's the only reason to need such memory speed really.

So theres no advantage going from 1333 to 1600 or 2200?

Pardon, I misunderstood, I thought you had 2200MHz RAM already. You will see some benefit moving to faster RAM on your system, just not as much as one would see with an Ivy Bridge + Z77 since that platform can keep scaling with RAM speed up to about 3000MHz (depending on your CPU's IMC and your RAM)

You all have mentioned a 10% increment -- that would only be 1-2 more frames in the most intense airports I fly I into. Is that worth paying the extra money for?

Omni, it's completely up to you whether you think an extra 3fps is worth it.

 

I'm on a 2600K and went from 16GB of 1600Mhz ram to 8 GB of 2133Mhz ram and picked up that roughly 3 fps.

 

For me it was worth it as I bought the faster RAM for approx $85 AUD and sold my other RAM for slightly more than that and picked up some extra performance. I did this atleast about 6 months ago.

 

RAM is cheap these days so I say go for it and sell your old RAM to make back some or all of the money, but at the end of the day it's your call and depends on your budget.

 

If you can, overclock that CPU more and you will see a far greater performance improvement. FSX loves raw CPU speed.

Hi

I run My @2600 cl9 1T , thats a good compromise cant get it better My mems is not 100% stable with cl9 @2666

To get the same perf in fsx i need 2800mhz cl10 and that need to much imc voltage to suite me.

 

Hasse

Faster RAM does help for FSX. I went from 1600 to 2133 and got 2-3 FPS more. Might not seem like much, but every bit helps. If you can gain 1-2 FPS for every computer part you upgrade, this will make a big difference altogether. In you case, 2400 or 2600 shouldn't matter that much, but yeah, faster RAM is beneficial.

Thanks, I might get this ram, its cheap and can be overclocked to 2200 http://www.newegg.com/Product/Product.aspx?Item=20-147-096

Damn it, I just got back home from a party, a bit tipsy and ready to delid my soldered 2600K with my timber axe, where's that thread again? :lol:

Well I bought this ram, 1600 http://www.newegg.co...Item=20-147-096 and overclocked to 2100+

 

System seems a little zippier, did some preliminary testing with FSX -- I think my stutters are gone, and the system feels a little more stable.
