Bottleneck question...

post #1 of 11
3/30/11 at 10:35am
Thread Starter 
I just built this rig recently:

Cooler Master HAF 932 Case

Corsair 750TX PSU

i7-870 @ 2.9GHz with a Thermaltake Frio Heatsink

EVGA P55 SLI motherboard

EVGA GTX 460 1GB

The rest are just leftover parts I had around such as the HDD's and the memory which is some old samsung memory I had laying around which Im not sure what speed it is but here is the CPU-Z page:




Later this year I will probably look to upgrade the memory and the video to the:

GTX 590

or something similar and I just want to make sure there is nothing that would be a bottleneck for it in terms of the CPU or memory and Im not too sure how the bus speeds work and should be set between the CPU and Memory.

Any help would be greatly appreciated.

That memory is pretty slow, only running at 666MHz which could bottleneck or system depending on what you are using it for. It probably wont hurt you to much right now as far as gaming goes as your GTX 460 would probably be your limiting factor right now. However, if you get a GTX 590 then your ram speeds will certainly be your weakest link. I would recommend getting some fast ddr3 ram when you upgrade your graphics card.

a 2.9GHz i7 and 8GB of 1333 DDR3 won't bottleneck a GPU in gaming. You could always squeeze a couple more fps by OC'ing though...

That's double-data rate memory. It's running at 1333.(666*2=1333MHz)

So would this be a good memory replacement to get?

Thanks for the reply...Ive always been meaning to overclock this system as well.

How far do you think i could go with the processor, are the i7-870's pretty easy to overclock?

No need for a memory replacement, it's running at the correct speed.

4 GHz has been reached with those chips pretty easily on air.

I'd recommend this to start educating yourself on OCing. These guys break it down pretty well.

I like 1600 ram for mid-range overclocking, just a personal pref. I get to run at 1.5v and that pleases me

oh I know...Im just looking to improve every little thing, But if you are saying I wont notice any difference between this memory and my current memory then I may not bother with it.
