You're guessing. This is why it is helpful to overclock and stress test each component individually. Then if it fails, you know what is failing, and what voltages to adjust.

By keeping everything stock first and testing, you know that the stock speeds are stable. Then you can leave them and adjust only one thing, like the CPU, or NB, or the RAM.

Well you could OC the GFX card by using MSI afterburner and AMD GPU Tool. The PCIe adjustments in the BIOS are more for CFire, TFire and QFire setups from what I know.

It is also possible to change the PCIe frequency in the BIOS from 100MHz all the way to 150MHz. Those are the Possibilities but I wouldn't recommend that being that I don't have much experience that field, YET!?

You know, I read up on the Gigabyte board and it seems Pretty strudy, structurally. I like the way that the MSI looks the most, then the Asus. The gigabyte just looks kind of Girlie in my opinon but that doesn't relaly mean anything... Looks will Always come in second place to Functionality.

So, if you're trying to run your Ram at 1333Mhz. 7-7-7-21-28-1T should work just fine. BUT if it's low voltage, you may want to bump the Dram voltage slightly to stablize it.

Side note: You shouldn't need to take you CPU-NB Voltage past 1.3 for 2800Mhz to become stable. My CPU-NB is Stable @ 3000Mhz with only 1.40 in BIOS and 1.43v in everest. 1.44 in everest during full load (Prime95 Blend test). BUT, every system is different.

Are you running the Blue slots?

you mean the DIMM 3 and 4 slots? no, why?

Ill try the ganged but i play alotta multi threaded games...Im glad you got 3Ghz NB stable that was defiantly something i couldnt do prime95 blend always failed in the 1st 2 minutes. 5-6-5-24@1333 is supposed to be faster than 7-7-7-24@1600 but its not in everest but i think thats do to the 1333 bandwidth vs 1600 but i benches 5-6-5-24 is faster.

You shouldn't touch the PCIE frequency unless you know what you are risking...that can do damage to your HDD's and more


On to something important

What is everyones opinion on NB speeds?

I keep hearing that it actually will have little to no effect since a run of the mill HDD will just bottleneck a fast NB...so it really gives limited to no gain when you OC it

I have upped the pci express freq from 100 to 110 using AMD's Overdrive but thats as high as i dared to go. If i remember correctly it made a little less than a 10% gain in my 3d 06 score. I only did that while benching , normally its set to 100. I really don't know what the risk was to my equipment but at the 110 setting i got some artifacts etc, so thats where i stopped.
I used the program AFTERBURNER to OC my ati 5770 and nvidia's NTUNE to tweak my 9800 gtx +.

You talking about CPU-NB? minimum CPU-NB should be 2600. It helps alot with information between the GPU-RAM-CPU. Thats where the CPU-NB really helps dont worry about hdd speeds thats what RAM and caches are for.

FYI - In regards to my question to MSI Tech Support about the max safe temps on the NB (790FX chipset) on the 790FX GD70.

80 degrees C is the Max temp for this north bridge.

Because with the higher speed that these systems run, you can actually gain more stability so to speak with the longer traces.

Read THIS and pay close attention to what M_S has to say....

That's really wat it comes down to is what you do with your PC and what the "real world" performance is like.

Rewind I was only giving a suggestion to the fellow...

I saw that thread that you are talking about. It will still have an affect on overall bandwidth making everything more efficient... To each there own I guess. It's more for multitasking. Like Running downloads, moving large folders, running uploads, burning DVD's on the fly and playing games all at once.... But remember rewind, ULTIMATELY (IMHO) it's all about having fun with it and making connections. Not just in the PC but you and I and everyone else. If none of us wanted to try and improve our PC's we probably wouldn't even have this thread to come to... Right? Just a though good friend...

PS. I have a OCZ SSD... Plan on getting another one.

Yeah, I was only giving an example of how some may use this feature. I don't at this point. BUT, some have also claimed that it brought stability to unstable system before. But that may have been with other setups...

I believe that he was dir d. Also with the CPU-NB frequency, the higher one run their ram, the higher the NB needs to be. the CPU-NB frequency should be "At Least" three times the frequency of the ram for efficiencies purposes. Example: Ram is 800Mhz (Double Data Rate of 1600Mhz) the CPU-NB would need to be 3 x the 800. 2400. AT LEAST. So if I plan on running high Ram then I want to make sure that my NB can handle it first... Same with the CPU and GPU.

Similair analogy..... If Auto Companies make many, faster cars but do not increase the width and speed of the freeways between Cities and States, what's the point of making faster cars? Silly to look at it like that but it chows it in a different light...



Good point mduclow. Max Temp is 80*C. Doesn't mean that it's a good temp to run at though. I wonder if they (the NB chipsets on these boards) have an "Optimal" heat range. or if it's just cooler is better.... IDK.



MERRY CHRISTMAS EVERYONE!!!!!!!!!!!!!!!
