Hello again, I'm still upgrading my Computer, now I'm planing to buy a I7 6700k and a mother board with z170 chipset. I don't have doubt about it.

 

But, about RAM, what is more eficient? 16 Gb DDR4 at 3200 Mhz, or 32 Gb DDR4 at 2666 Mhz?

90% of your uses will benefit more from more RAM. I've yet to find a situation where I personally would have benefitted from faster RAM.

 

I say go for the 32Gb, to be more "future proof" with DCS and other programs.

Faster ram is sometimes a good thing when you are working with virtual machines for example, but for most cases, more is always better.

not really needed anymore for overclocking modern CPU's as those CPU, RINGBUS, FSB, etc.. clocks run independent now.

 

With a 1st gen i5/i7..yes... those needed fast RAMs or luck that your OC works. The FSB is the only thing those will OC with, but actually, faster RAM not needed as well, it just gives you more options.

 

 

Stil, fast RAM is nice but it pays off rather seldom in selected scanrios only, tbt.

So, I will search for a good cost-benefit with 32Gb.

Someone knows if DCS 2.5 will require only 16Gb or more?

no game requires more than 16GB, but you can leave your 144 webpages open and your 6 other programs running and do a mission in between to clear your brain.

Barao, it doesn't look to me like you need a new computer at all. Since you have an 8GB video card, your 8GB system RAM is plenty. Fast RAM affects load times, but not framerates.

 

Your bottleneck is probably your CPU clock speed; the Q9550 should easily overclock to 3.6 GHz, possibly to 4.0.

 

I have a 'bad' Q9650 (very high VID) but at Intel's max recommended voltage (1.3625V) it runs at 3.6 GHz no problem. It will go over 4.0 if I push the voltage up to 1.45, but I don't have to, the CPU never bottlenecks DCS World on my machine, even at high framerates with high graphics settings (I have an old vid card, I'd love a 1070!!).

 

Since you have a great video card with tons of video RAM, simply try bumping up your CPU clock to the highest it will go, it'll give you a lot better framerates because there's no way the system RAM is what's limiting you. You can buy an expensive new rig if you like, but DCS runs very well on old machines with great cards like the 1070... you just have to overclock the CPU enough. Core 2 Quads will do 3.6 GHz or more easily, and DCS World only uses two threads, so expensive i7 based machines while nice are not really necessary.

The minimum spec is 16Gb on 2.0. However, nothing has been mentioned about an increased minimum spec for 2.5.

 

It never hurts to over spec a PC when you upgrade, because sooner or later you will hit the ceiling. Why not make sure you have as much headroom as you can afford now, to avoid issues later, which will just mean even more expense?

 

Realistically speaking, I'd suggest 32 Gb ought to be the minimum spec right now. I put 64 Gb in mine. Over the top - certainly, but if your Mobo will support more, where is the down side?

16GB of RAM will be enough for DCS and most other applications. I have upgraded my RAM from 8 to 16 about half a year ago. But honestly, it also ran well on just 8, both 2.0 and 1.5 with everything on high and in multiplayer servers. Some people do have some real issues with 8GB though, but 16 is enough and you can always add 16 more if you really need it.

Yes, I am considering this too, but by the end of the year we have sales here, and if prices fall, I will enjoy buying a new system.

 

My Quad Core is not unlocked, I need to change FSB and the memories is not so good :( So I achieve 3.4 GHz at the top.

In the bios, set your RAM at the lowest setting (or at 800Mhz), then you will be able to overclock properly.

The downside is that more memory costs more, and huge amounts of it are money wasted because it isn't used.

 

When they specify minimum RAM, do they include VRAM? Remember, the O.P. has a GTX 1070, which has 8GB of VRAM... so, 8GB of system RAM is probably fine (16 GB total).

 

I find my 8GB system RAM to be enough for DCS 1.5, even with my wimpy old 2GB video card... but 2.0/Nevada stutters constantly and is unflyable. With an 8GB video card, that probably wouldn't happen.

 

In any form of gaming, including DCS World, most of the RAM used is for graphics textures, and modern flight sims, because they have enormous, detailed ground maps, use huge amounts of VRAM. The system RAM is mostly there for texture swapping from the video card when you run out of VRAM (which is what causes micro-stuttering).

 

With enough video RAM, you don't need as much system RAM. Some people with GTX 1070 or 1080 cards (8GB) can run DCS 2.0 on 8gb system RAM no problem.

It just looks to me that your system should be fine for DCS... What, if any, problems are you having?

 

There have been benchmarks done for DCS and any CPU with a high enough core clock should do the job just fine. Framerates don't seem to be affected by CPU type, just the clock speed.

 

Go into your BIOS settings, your max multiplier should be 8.5, and if you have 1066 MHz memory you should be able to run it a good chunk faster than 3.4 GHz (which, actually, is just about fast enough, but a bit more never hurt).

 

I have a Q9650 with a max multiplier of 9 (also not an 'unlocked' CPU), but I only have 800 MHz memory, and I can get it up to just over 4.0 GHz without too much trouble (and mine is a 'bad' chip with a very high VID).

 

Try setting your FSB Strap to Auto, set the RAM speed to 800 MHz when the CPU is running at default speed instead of 1066... then overclock until your CPU is running at 3.6 to 4.0 or thereabouts. You don't need a higher multiplier because your RAM is quite a bit faster than mine, you just need to set it's speed in BIOS appropriately before overclocking.

 

I'm pretty sure your computer can run at 3.6 to 4.0 GHz without trying too hard. With the excellent video card you have, 8GB of system RAM should be enough, because you actually have 16GB of total RAM and DCS World's memory requirements are nearly all for graphics textures anyway. Any framerate issues you might have are being caused by your current 3.0 GHz CPU clock, not the speed (or amount) of memory your machine has.

This explains why my system uses 7.5 GB RAM and 6.5 VRAM when I'm in the Blue Flag campaign. My GPU memory is replacing the lack of RAM.

Actually, it's more like the other way around, any game will use your VRAM first and then use system RAM when you've used all of your VRAM. When you fly around the map in DCSW, textures are loaded into your VRAM, and if you run out it will swap textures back and forth between system RAM and VRAM as you fly around. That's what causes the micro-stutters.

 

If you run out of both VRAM and system RAM, it will swap textures to the hard disk (or SSD) which causes mega stutters :)

 

That's why DCSW is best with video cards that have huge amounts of video RAM. Yours is about right :)

It is true and not true same time, it depends what CPU you use and if you intend to oc BusClock.

 

my last CPU's I overclocked went to the same clockspeed with either 1600MHz or 2133 MHz on DDR3 sandybridge 5.0GHz or this new one anywhere from 40-4.6 GHz, regardless of what the ram is at.

 

I use a 102,3 busclk now and I thinK good RAM would and should tolerate such a small deviation from the standard tested and certified speed. 2800 vs 2860 ...those 60MHz dont need another module or faster RAM at a higher price ( mine are 3000 anyways )

 

 

I did a lot of TESTING, also with the new 5820k with an Asus WS X99 board that sits on my table, with quad-pumped RAM....the thing is...my 6700k has a HIGHER score in memory benchmark than the quad system at 2133 ( mine was at 2800 ).

 

That 5820k needs some serious OC to break even with the 6700k dual channel at 4.6/2860 MHz.

 

 

Bad thing with anything past 2600is that my board raises Voltage on VCCIO and VCCSA to astronomical red values...and you cant hinder it doing it. I have to change it after every boot in GUI...which is BS.

 

That Asus X99 WS/IPMI board smokes that MSI in 1st gear. Asus still rules, I tried again and failed. MSI is way behind, colors are nice, but under the hood its inferior. A gamer Bios that lacks many things any standard Asus board features ( like the Z97-K ) and misses extras for that kind of price tag that an Asus WS board features that aint a dedicated OC board but WorkStation as labeled, still it offers better oc fine tuning than the gamer board from MSI.

 

 

Forget those MB tests on all those sites, all Blah blah NICE....they look morte for LED connectors than rock solid and straight forward design these days.

 

In addition, my pal's new i5 4th gen uses low profile Kingston Value RAM 1600MHz......and scores 2900 Benchmark IPC's at 4.8 GHZ ( 3.4 stock ).

No need for faster RAM tho I will give him my 2 x 8GB 2400 DDR3 as I dont need them anymore ( if they fit the DRPro3 cooler ).

 

If those were all non-k version...yes...then FSB is the only way and faster RAM makes math easier, but still, there u might find a spot where your RAM speed just fits again. You dont need to raise it, you can, but it is no MUST.
