2400 or 2600 MHz RAM for Ivy?

What do you mean by that.

 

As in bang! Time to buy a new CPU

Why? Memory works fine overclocked. 1.5 volts. Read the reviews, best ram available for the price and the ability to overclock like mad

I was not aware of that

 

Maybe I will give it a try....what review?

 

If I burn my RAM sticks will you buy me some new ones?

Doesn't faster RAM help with stutters? I never know because my RAM isn't very fast. 1866mhz and I'm on a board that really doesn't take great advantage of it. I realize the Z77';s + IB + fast ram are more noticeable.

Can anyone please advise then the best value RAM to get with a Z68 board ? I presently have 1600 MHz, don't particularly want to overclock it.

Depends on your chip's IMC. If you can get 2133MHz or higher, go for it. You won't know till you try though. My chip can handle up to 2680MHz so I run my RAM at just over 2600MHz with fairly tight timings.

Try reading the link I posted and click on feedback.

 

And no I will not buy you lamb chops.

I'm running 2133 memory and to tell you the truth there is probably little or no gain in FSX. Keep in mind that the IB memory controller is only rated for 1600ghz memory. Yes you can run higher but really the difference is tiny. To prove this you only need to watch the memory usage panel in Win 7-8 resource manager. Note that it is never taxed under any circumstances in FSX beyond 1% even with 1600ghz memory. That said go for the fastest memory you can afford and you MoBo will support IMO. Just remember that you will be gilding the lily after 1600ghz.

Why do people make absolute statements like this with absolutely nothing to back up their opinion? Go check the FSX Mark 11 thread. 10% gains moving from 1600 to 2133 or higher.

Check the Windows resource manager. Its very revealing as to what FSX needs for memory speed. Cheers jja

I dont care what Windows says when benching not now and not ten years ago,

Its a LOT odd things there remember the Ricky tweak 100% CPU load in win.

Here is a list of mems i tested in FSMark11 on same hardware only swap mems.

All of them tested with the same 3770k at identical freq , tested th 2700k with the slower mems and

With the team 2800 downclocked.

OCZ 1600 4gb

Corsair 1866 ven

G-Skill 2133 Rips cl11

G-Skill 2133 Rips cll9

G-Skill 2666

G-Skill 2800

Kingston HyperX 2666

Team 2800

Team 2666

Team 2600 ev(ES)

 

The fastet pair is the team 2600 , that dit in My PC today

Its up to you if you think a 1333 set is faster or 2133 i dont care its up to you

I know what iam thinking

 

Example 1866 avg 51 swap to 2666 wops!! 56 avg

Dont remember all benches i published , have run alot of hours.

Have unpublished suiside runs +5.5 IB with thight timings +1.8v mem

Not really a computer techie so how do I find that out ? My motherboard is a Gigabyte Z68AP-D3 rinning my i5 2500k at 4.4 Ghz

Thanks Paul

There is a very good reason why the performance difference between 1600 and 2400 memory is trivial. (This info is confirmed by MSI techs on the MSI Mobo forum). The reason is CAS (Column Access Strobe) which has a significant performance effect on memory with the lowest value being the most performant. Several memory generations back we would buy memory with a CAS of 2 which had a huge advantage over memory with a CAS of 3.

 

Today CAS is higher due to memory density but 1600 memory wins hands-down over 2400 because its CAS is usually half (or more) than that of 2400 kits. Yes raw speed is useful but CAS is what you want to be looking at.

 

I have great 2133 memory with a CAS of 9 but even these have little advantage over 1600 kits with say a CAS of 6.

 

Finally another big factor is data rate. 1 is considered to be 2x as fast as a data rate of 2. My 2133 mem cannot run a data rate of 1 where as most 1600 kit can.
