Okay, 1T worked as you said with no noticeable ill effects.

But, when I ran Cinebench, I was surprised to see the 1T score be lower at 8.03 than my 2T run of 8.25. Should I be concerned about this?

Most intel based motherboards don't cooperate well with 1t command rates even if the memory module is able to support it. Most times it will produce memory corruptions (especially with overclocking) which results in very poor performance.

AMD also has the corruption and/or performance degradation when using (overclocking) 4x sticks. IF memory performance is your main concern then I would suggest purchasing 2x sticks of 8Gb for 16Gb instead of 4Gb x 4 sticks as it will significantly increase overclockablility .

I'm good with all this, and it wasn't my intent to have you rehash for me the 1 bank vs 2 bank points. I will go on further to say that I have yet to run a test that fails on 2 banks and passes with 1 bank. May just be the type of testing I'm doing and the combination of parts of I have.

But in this case here, I have two working scenarios. One with 1T and another with 2T. Using Cinebench as the test program, the results showed 2T to be faster than 1T. I don't really care if the memory is faster in one over the other. I'm more interested in overall system performance. That's what I'm looking for feedback on. If I simply rely on the one benchmark, I would conclude my system runs faster at 2T than 1T, right?

Just in case my post is unclear, what I'm asking is, when looking at overall system performance, is it better to tune the system with a test program like Cinebench or, is it better to use test programs that look at individual areas of the system like IBT or Prime95 or WPrime. My main application is gaming, so tuning for that level of performance is of most concern to me.

Anyone have any idea when we may see a 1090fx board or whatever they decide to name the next series? I know this one just released in sept. but i'd hate to buy one just to see the new one come out a month later. I've grown tired of this msi 890fxa-gd65 board. It is a good board just not great for overclocking. Can't get much more out of it by adding voltage than just leaving voltages in auto. I could only keep 4.0ghz stable on my 1090t longterm and 4.8 ghz with my new fx 4170 with H80 cooler push/pull. Both cpus and the cooler i've lapped. 230-240 fsb is all i could ever squeeze out. Can't wait to see what i can get out of the asus board with the same parts.

I had to read your post a few times to figure out exactly what you're driving at but let me take a shot. biggrin.gif

The idea of 1090FX would mostly be about AMD and their ability to provide a new chipset. Given that Asus just refreshed the CVF, I would be surprised if you would see anything new for a few more months.

I've seen people have good results with higher-end Gigabyte boards overclocking the newest AMD FX offerings. For instance, with conventional water cooling, you shouldn't have any trouble getting a Vishera stable at 5 GHz.
But if you're only concerned about Phenom II X6 or FX Bulldozer, then I don't think waiting for a new board is going to get you much more flexibility in overclocking than what you can get with the Z board. The Z board's big contribution apparently has to do with providing additional phase control on the DRAM interface. In my own experimentation, I believe DRAM makes more of a difference in system stability here than when you get into overall 20% system overclocking, so that upgrade alone seems very valuable.

Good luck with your decision.

lol...i must say i m like gr8sho about your post....i tryed to understand it but it s not easy
i m stuck on "1090FX"....rolleyes.gif.....what do u mean exactly? 1090 remind me Phenom II .... never heard of such a board ....what is it supposed to do? (which socket? for which cpu?) biggrin.gif

I just picked one of these boards up its the ROG version, doesn't look like much if at all any difference between the normal Asus and the ROG board, I know this thing will hold my two ge-force 8800gtx gpu's, however I got three questions and I know the best answers will be here:
1: I think I'm going to need a 850w psu for the twin gpu's on this mobo, and would a 1000w be overkill and is overkill bad?

2: knowing the steamroller will be out sometime in Q2 would it be worth it to invest into the 8350 still?

3: what memory will work great with this board for O/C I'm determined to hit the 5ghz

Just in case my post is unclear, what I'm asking is, when looking at overall system performance, is it better to tune the system with a test program like Cinebench or, is it better to use test programs that look at individual areas of the system like IBT or Prime95 or WPrime. My main application is gaming, so tuning for that level of performance is of most concern to me.
Well let me answer you by allowing you to answer these questions:
How often do you disable your GPU and allow your cpu to render your games?
How often do you play your games at resolutions @ or less than 720p (1024x768) ?
If you answer "not often" or "never"...then Cinebench will show you nothing in regards to total system stability except for CPU rendering and CPU core stability.
So the question then becomes "which benchmark should I run?"
Well, this answer varies between users based mostly on preference.
My weapons of choice vary choice depending on the application I am tuning for...
For DX10... I use Vantage(physX off/set to CPU)
For DX11...I combine Heaven and 3dMark 11 (Mostly heaven @ 4xAA +Max all else)
For a basic overview of non-video system performance PC Mark 7 works well as does Sandra.
MAxxMemm is good for testing memory (ram) performance
Wprime is good for testing performance/stability output of your cpu+ram combination.

The question you asked is the number #1 issue most overclockers run into while attempting to reach maximum performance from their hardware...
and my answer tot hat is this:
You could either have "good" overall performance or "great" application performance. The diff. is tuning (not only clocks but the OS as well) your system for
the application to which you want to perform the "best". If it's DX9/10 gaming your going for and your monitor resolution is at or less than 1080p then you'd
want to emphasize cpu and memory clocks... if you play your games at 1080p or higher then you want to emphasize FSB, PCI-e, and video card clocks. But
that all depends on how the application or game is encoded....for example... WoW(pretty much all mmo's), Call of Duty series, Skyrim (OEM/not modded)and pretty
much all Console ports are CPU biased despite the resolution, whereas; Metro, Battlefield 3, LA Nior, Anno and Max Pain are GPU biased and perform"better" at higher resolutions given
you have the available v-ram to allow it.
Basically, what you want to see in games which are more gpu biased is a 90%+ gpu load while running them.
If the load is less then you most likely have a system "bottleneck" prior to the gpu's output, and since most games are either single ir dual threaded this "usually"
requires a minor overclock of the CPU. By "minor overclock" I mean our rule of thumb over @ the nvidia forums is 3.6Ghz on Intel / 3.8Ghz on AMD (using modern a modern GPU or SLI)...
so could see that most modern CPUs do not have this problem.

We will not see a new chipset for quite a while, all 990FX chiped mobo's will work perfectly fine with upcoming CPUs if that's what your asking.
As far as your 1090t is concerned... What you have now is pretty much what you can expect out of it. 4Ghz "stable" is good for that CPU. Same goes for your 4130.
I would not expect more from upgrading your motherboard. From your post you seem to be attempting to overclock via FSB which the FX cpus don't really like as much as
the previous generation AM3's...just like the AM2+'s would do 400+ FSB all day long and was the norm. Also, when adjusting FSB you have to remember that ALL other
components come into play which you did not decide to mention in your post.

Thanks for taking the time to write.

I've used Heaven before, so I'll look at that again. The game that has my attention right now is Far Cry 3 which is DX11 and is running at 1080p. The two GTX 460s in SLI seem to be able to do a reasonable job, but it feels like they are at or close to be being at their end in terms performance for new games. This game is significantly more demanding I feel than Skyrim.

I've run FC3 today with 1T just to see if it worked ok. I did have the game crash once today which it never did at 2T. I'll try it for a bit longer. I have a little more headroom for DRAM voltage still.

About your point on which subsystem saturates first, there's no doubt my video cards are in FC3, the system overall seems like it's humping. The fans scream pretty loud and package temps can get to 54C.

...and speaking of overclocking the FSB, has anyone experimented to find a sweet spot with the 8350?
