Learning to build a new computer.

xspada · Apr 19, 2014

Hi there tomshardware community,this is my first post here.I have been searching for the internet for some time and I do not find an answer for my questions.I have a very little knowledge about computers and I will really appreciate all helps and advices.

So here is the story.I wanna build a budget pc just for casual gaming and home use.I have this spec in mind-

CPU-AMD A6-6400K
Motherboard-ASRock FM2A88M-HD+
RAM-KINGMAX DDR3 1600MHZ (2x2) gb

I have a pc case with 450 watt psu.

Questions-

1)Will it work?I mean is there any problem with my setup?
2)I know that APU intergrated gpu share the system RAM,is that correct?
3)This will get a little confusing.Say I have (1x2) gb RAM and (2x2) gb RAM,can I run them on dual channel?If it can,can you please tell me how?
4)If the APU share the system RAM,will 1 GB is sufficient to run a game on 1024x768 with low detail?
5)How much does GPU memory affect gaming?
6)This is my final question.As APU share system RAM,if I set 1 gb of RAM to APU,will it still run on dual channel?

Im sorry if my english is bad and the question are not clear enough.Hope I post in the correct section.Thank you.

1)Will it work?I mean is there any problem with my setup?
it will work fine

2)I know that APU intergrated gpu share the system RAM,is that correct?
yes

3)This will get a little confusing.Say I have (1x2) gb RAM and (2x2) gb RAM,can I run them on dual channel?If it can,can you please tell me how?
you can only run dual channel with 2x 2Gb
if you put another 2GB, you lose dual channel advantage, but you gain more capacity
i prefer more capacity than dual channel
because you have to allocate 512BM to 1GB ram to the iGPU itself

4)If the APU share the system RAM,will 1 GB is sufficient to run a game on 1024x768 with low detail?
1gb shared ram is more than enough

5)How much does GPU memory affect gaming?
faster ram, = more performace, but it is only 5-10%

6)This is my final question.As APU share system RAM,if I set 1 gb of RAM to APU,will it still run on dual channel?
if you use 2x 2GB, yes you still have dual channel

Im sorry if my english is bad and the question are not clear enough.Hope I post in the correct section.Thank you.
