I am making a build with real tight budget. I want to know if is better to pair my A10-5800K with 8GB 1866MHz or 16GB 1600MHz??

What exactly is your budget and what are you going to be doing with this computer?

Motherboard: ASRock FM2A75M-DGS - 55$
CPU: A10-5800K - 150$
HDD: WD5000AAKX - 70$
Case: Thermaltake V3 Black Edition - 60$
PSU: Corsair CX500 - 60$
Memory: ????

I am limited by my location to more option, the ram both are like 70$ for the 1866 Mhz and 80$ the 1600 Mhz ram, both have a cas latency 9 both. My limit is 400$ but i can get a little more if the difference is few.

Since you are not getting an aftermarket GPU then go for speed. 8gb is enough for just about anything even after you take away the iGPU's share away.

Also, 500w is way overpowered for that build. Unless you're planning on adding a GPU later on 350W would be enough even for setting up 6670 hybrid crossfire.

I am planning getting later a hd 7870, a wifi pci card, and a dvb-t2 pci tv tuner. So i want to make sure that could be possible.

If you are going with iGPU i would go with 1866. I run DDR3 2400 TridentX's overclocked to 3000mhz and the differences is around 12 FPS over DDR3 1600 so yes faster Memory is important.

Anandtech did the intel vs AMD integrated showdown as to what performance better, with Trinity faster memory scales peformance exponentially, Intel not so much 1333 to 2133 showed hardly any gains on the iGPU.

If you're going to be running a dedicated card there is no reason to get the faster ram since 8g 1600mhz will do fine.
If you're using the IGP for quite a while, it would be worthwhile to get 1866mhz ram

The cheapest 1866mhz 8GB set is only $10 more than the cheapest 1600mhz 8GB set

I selected the wrong tridentX kit, thats got the ram cooler which you don't need the normal trident x 2400 come in at $70 so $20 less then you just need a case.

Yeah this is about right though 8 gb for nearly anything, unless you are running a lot of virtual machines, however amdx64 and iGPU's like memory OC's. I just picked up 8 Gb of corsair vengeance 1866 for $45 dollars, the timings are at 9-10-9-27 I was able to get all the timings to 8-9-9-26 with out a change to the voltage they could probably go further but I'm going to wait till I can pick up a better motherboard to OC any further. You could definately drop about 100W off the PSU if you absolutely must stay under 400, but idk where you could get a power supply any cheaper than you already did. All around pretty well rounded for a gaming machine though, it should work out nicely with the 1866 ram.

That is a good option but newegg is not a option. I am geographically incapable to buy in USA. Also I need to get it quick the ship to my country could take up to 10 days.

Don't get A10 if you decide to get 7870 later. Just get a Pentium or i3. You'll still be able to do everything but games until you get the 7870.

My recamend is fill all slots dont see capacity. see mhz in board and ram.Reason mhz is the key to achive speed. if board support 1600mhz u insert 1333mhz its waste because not get full speed of ram slot. if board support 1333mhz u insert 1600mhz its also waste of money (1333mhz ram is cheaper than 1600mhz)also u not utilise full speed of ram. (2x4Gb=8Gb 1600mhz=3200mhz =3.2ghz) vs (2x8Gb=16Gb 1333mhz=2666mhz=2.6ghz).

A lot of testing shows the i3 3220/3225 and the A10 5800K being very close in discrete performance, the one thing I don't agree on thouch is while the A10 is being tested on its ideal platform price wise, the i3's are being tested often on Z77 Sabertooths which are completely unrealistic platforms and add around 3-5 FPS onto performance on the Mobo alone, considering the Sabertooth R3 is around $250 and the 3220 is $130 its not a good synthetic, the i3 on a B75 or H61 will represent different results and considering how feature skimped those chipsets are the A85+A10 or A8 5600K is by far the winning platform discrete or integrated.

Grab the A8 5600k would save you some cash and you do a minor OC to boost the CPU to A10 levels

If you are using the iGPU, then frequency definitely matters. If you are using a discrete card, then not so much. Lots of places have tested this (including myself personally). Someone mentioned the Anandtech article, but here is the actual link to it: http://www.anandtech.com/show/6347/amd-a10-5800k-a8-560... . We did an article specifically on how much RAM speed affects AMD iGPU gaming, so you might want to check that out as well: http://www.pugetsystems.com/labs/articles/Optimizing-AM...

Since you are upgrading in the future to a discrete card, I would say it doesn't matter as much what speed of RAM you get. However, you also probably don't need more than 8GB of RAM either unless you are doing something like 3d modeling. Gaming definitely won't use more than 8GB of RAM, especially at the settings you will likely be playing at. So if the choice is 8GB of DDR3-1866 or 16GB of DDR3-1600 then I would say get the DDR3-1866 since you will at least see a performance boost until you get a chance to get a video card in your system.

Okay let me just end this thread right here. Check youtube for NCIX's review on the AMD A-10 and how much the HD7660d benefits from a faster ram clock. In summary linus compared a 1066MHz DDR3 to 1866MHz DDR3 corsair dominators. It showed a 40% increase in performance with the dominators (Black Ops = 35 fps of the 1066MHz ram to 50fps with the domiators) . Bottom line - The Trinity A-10 relies almost entirely upon the speed of the ram not the quantity. If i was you i'd get 8GB ram possibly with a higher clock 2200MHz perhaps? Hope i helped you out
