Which RAM with a APU & GPU combo

[Capn_Tack]

Quick question: if I use an AMD A10-6800k APU, I know that by itself it needs 2133MHz RAM to keep up on graphics processing. But if I throw in, say, an ATI 7750, does it need RAM of that speed? Would even the APU graphics pull off the 7750? If not, I suppose the faster RAM is the way to go. Now if it does, is the faster RAM worth it for the rest of the system functions?

You only need the fast ram if you go with the APU. But if you're throwing a 7750 in there, might as well change it to fx6300. But if you already have the a10, don't get a fast ram, a 1333mhz or 1666mhz would be just fine.

I am considering an FX CPU, but I am doing a mATX build. I don't like the FX mATX mobos.Assume I must use an APU, how will RAM speed, the APU, and an added GPU/lack thereof interact with each other?

Dont wrry the performance wud be upgraded from 7750 so there is no need for the apu graphics let the 2133 ram run nt a problem
Havin 2133 ram is like a 25mhz increase in your gpu clock



Hope it helped

What would the best performance out that be: let the 7750 run things, or dual graphics it with the APU?

 

[Sn1992-1361850]

7750 will be bttr

So what is the point of dual graphics then, if the GPU alone performs better than the GPU & APU together?

 

[Sn1992-1361850]

Yes there is no point of dual graohics as the gpu and the apu graphics are f different generations
It is not possible to use dual graphics as the one is 7 series card and the apu is havin 8 series graphics






Dont frget to close the post

I have seen several people say the A10-6800k APU can be used with the 7750. The 8000 series on the APU is basically a rebranded 6000 series. In fact the officially supported GPUs are still only 6000 series, not 7000. But several people I have seen got a 7750 to work. But was wondering if anyone knew of the RAM speed needed to be higher even with the 7750. I don't know of the APU pulls ram off of a discrete GPU once added.

 

[Sn1992-1361850]

No they dont
Apus graphics processor only uses ram
The gpu is discrete it will have no effect from ram the 7750 runs seperately


Srry i got a lil cnfused
Gt ur point now
Hope its cleared

 

[Capn_Tack]

OK. So just to be clear: the APUs graphics will use the MoBo RAM, and the GPU will use it's own. So I will want faster RAM on the MoBo either way. And as long as the GPU is compatible, it should run better with Dual Graphics then just the APU or the GPU alone.

 

[Sn1992-1361850]

Yes very right

And if u r still buyin the processor and mobo dont go fr a apu
Get a 6300 and a better gpu like 7850
