While I disagree about the bottleneck being "Fixed" I think if you have no NB OC you will alleviate a lot of the bottleneck by OCing it and enough to tide you over to Steamroller/Haswell or beyond if you're ok with performance.

I always see people say "just use a clock multiplier" on some OC forums because of the ease of use, so I feel like I learned something today. I never realized how much the NB could make a difference. I will have to look around to see how far I can push it, but I do have one question: Doesn't overclocking the NB speed up everything? Like the ram also? Will the ram run fine at speeds other than 1333 or 1600? What should I be worried about?

I will read up on it so you don't have to baby me though it, but any tips would be cool. I had issues in the past where it wouldn't even boot past post, and I had to push the BIOS reset switch on my motherboard (RAM red light issue- still think it is the ram not cooperating) but yeah...

Check out the NB OC tonight and upgrade CPU/MOBO before you think of going TRI SLI.

I will hold off on upgrading my GPUs or adding until I upgrade the mobo and the CPU. Thanks. I agree with you that the next step is upgrade the NB and push what I have to the limit. I want to avoid spending more anyway as I already upgraded just last year. Thanks! I will try and post results once I do my testing...

P.S the reason why your RAM crashes at 1600MHz might be becuase that your Northbridge is at stock speed, if you can try to get it at 3000MHz, you might be bale to run it at 1600MHz, make sure you use the right timings also.

Another thing you could try is to put the FSB to 250, then up the multi from there, it can help keep your OC more stable.

If you are going to try for 1600MHz on the RAM tonight, I'd go for it, try with loose timings first like 9-9-9-28-34 1T, and if it boots, try 8-8-8-24-28 1T then 7-8-7-24-28 1T thumb.gif

In my opinion, it isnt worth it to go past 2 way sli, because of the poor scaling past 2 gpus. Also, if you are on the verge of upgrading cpus, you might as well see where you can push your current cpu to see if will give you the extra speed you need. Like someone said before, my phenom 2 x4 oced would hold back my 460s sli in some games such as bf3 multiplayer. Keep your temps in check, the amd processors, at least the phenom 2 I used to have, were recommending 55c max safe temps from what I read when I had it. Also a cheaper route could be to keep your current mobo and upgrade to one of Amd's latest processors, which from what I have heard are a decent upgrade from their last gen, and you could return it if you are unhappy with the performance after some tests.

Also, by the way, which games are you trying to run?

blinksmiley.gif Man starting to push my understanding, but I recognize what you are saying. I don't understand how your timings are "loose" or not but I will try it as you specify and do some research. I don't exercise my overclocking muscle enough I suppose. Anyway, thanks!

This is loose 10-10-10-28-34 and 9-9-9-28-34

This is what we call tight timings 8-8-8-24-28 and 7-8-7-24-28 thumb.gif

The tighter they are, the better = more performance if you get me, even though you might not notice the performance change until you get your Northbridge at least 3000MHz smile.gif

The reason I went with the 1100T was because when the FX (bulldozer) came out the benchmarks were saying that in gaming the X6 1100T outperformed the FX. I have not done research past then, but I was under the impression that the 1100T continues to remain as one of AMD's best. That being said, unless something truly remarkable comes out that I could upgrade to, than I will overclock to the limit until I switch to Intel. My next build is going to be over the top.

Thanks for the advice! Definitely don't want to upgrade with such a little upgrade... If only I could afford 2 Titans.

Just to add, if you did not already know, I would try to get your oc stable first before adjusting the ram so you are able to pinpoint which adjustments caused the instability. Its easier to figure out what is causing a problem when you adjust one thing at a time, than a bunch of things at once.

Good advice. I appreciate it. I always get a little impatient and do everything at once! I always get upset because my machine always wants to fight me. I try and do overclocks that others seem to find success with but have issues. That was last time I attempted to OC. Tired of random reboots and BSOD... Will try harder!

I think that's a wise choice. The thuban, SLi 670 combo is a very potent gaming rig and should provide good performance @ 1440p. Also people have this weird notion about how GPU should never be limited by the CPU which I find quite amusing. What maters is that the system keeps pushing out enough FPS for smooth game play. In a wast majority of games the min fps will be due to the GPU even if its paired up with relatively slow CPU and that goes double when playing at higher resolutions.

Only in a few games like StarCraft II, Plantedside 2 or Wow does the CPU become a bigger concern. Even then a Thuban running at 3,8 is no slouch.
