any change in performance?

nope..unlikely. As said...those are both pcie x 16 slots.

edit:
14970 3dmarks 06 on PCIE1
14970 3dmarks 06 on PCIE3

So..same performance!

[Mikael4a]

uh..AFAIK memset sets those in real time also right in windows.

Well yes but when you restart those settings still aren´t applied before windows boots so you can´t test them with memtest.

i think 5:6 then 1:1 is easiest to get high FSB

im new... i dont understand what the 5/6 and 1/1 ratios refer to??

[Praz]

im new... i dont understand what the 5/6 and 1/1 ratios refer to??

200/667....3:5
200/800....1:2
266/667....4:5
266/800....2:3
266/1066...1:2
333/667....1:1
333/800....5:6
333/1066...5:8

[carmatic]

thanks!!! ive been looking for something like that

my fsb is 442, and my strap is 333/800 , cpu multi at x8 ... so that gives 3.537ghz cpu and 1061mhz memory... i keep my memory at 5-5-5-18 and everything in the clock fine delay as more aggressive , then set the dividers to keep the ram at slightly above 1000mhz ... is there a better way?

[flexy]

its a try and error thing, depending how much your hardware can handle. Some dividers my board here doesnt like at all. I am also at 3537 right now, anything higher and i might need WAY more volts. Ram doesnt go too high either here.

[Russian]

nope..unlikely. As said...those are both pcie x 16 slots.

So, the second is the 4x non pci-e 2.0?

[Blackwhite]

Very often my comp don't wanna start after night - fans spining and that's all - there is no signal, nothing, I have to restet comp and then it's working fine.
I had the same on Abit IP35.
Any ideas?

[carmatic]

i know you guys have run benchmarks and all so i want to ask you...

what gives better performance, tight ram timings and low fsb or dividers, or high memory mhz with loose timings?

[Russian]

Do you mean mem freq? because FSB and Timings are unrelated. The optimal thing is to have high freq with low timings, but at a certain point if your freq goes high and the timings follow, it doesnt improve performance. The key here is a correct balance between the two and you need to find that by raising the mem freq and seeing where you start to lose performance. Then work down from that mem freq. and work on your timings.

Is this after a total shutdown? Standby? Hibernate?

Have you tried another PSU and seen how that psu reacts to the same situation? I find it near impossible to believe that two boards from two different manufacturers and different chipsets could have the exact same problem.

theres a setting called 'boot up clock' or something like that in the bios, try messing with it?

[flexy]

So, the second is the 4x non pci-e 2.0?

nope, its two 16x PCIE Gen 2 slots. 3rd, all the way on the botton is 4x

there was a very good comparison on some site..i think it was on an OCZ site where they did such comparisons.

As far as i remember...CPU speed, then mem speed

Some very few theoretical applications preferred a litle lower mem speeds but at tight timings, but for overall and real life performance more mem speed is better even at lose timings - so 500 mhz at 5.5.5.15 would be better than 440 4.4.4.12 (just as an example)

Is there any place i can see this at? i have just been getting alot of contradicting info.

In your manual.

My e8400 Q750A031 seems to be a bad batch
But it´s always core #0 that is unstable and core #1 that is stable. So could the GTL REF voltages help core #1 or some other settings?

It's after total shutdown.On my old Abit Quad GT was ok.

[zsamz_]

well my board is only happiest when on 69%gtl settings
n loves my ballistix over 1200mhz 2.09v
she even loves 500fsb

[Mikael4a]

By that do you mean you use 69 on all three settings? Iow

x CPU GTL1/3 REF Volt: 69
x CPU GTL 0/2 REF Volt: 69
x North Bridge GTL REF Volt: 69

I can get fully Orthos stable with 1.4V at 3906 (9x434) (1:1) but need to bump it to 1.4375V if I want to run 5:6 (1042). So do you think GTL settings could get me to 4GHz?

edit: your sig says e6850 or doesn´t that make a diffrence? can the new 45nm cpu:s take the same gtl voltages?

[zanzabar]

no thats not the same as teh % the gtl on this board is a number so u have to find 69% on your own, so if ur at 1.4V then u need 96/94 for the cpu gtl

69%
you go according to volts you using

my first inclination is the same as "Russian", your PSU might be the culprit...BUT...i did have cold and warm post problems on this board...it was intermittent...a guy suggested increasing the NB voltage and when i put it up in the 1.65v range it stopped and posted everytime...just a suggestion.

You're running a 65nm cpu though. Don't have one, but from what I've read they like the GTL's a little above 67%. The e8400 I'm running seems to like them a little lower, which seems to be the case for a few in the P35 thread as well.

OK, guys, I finally got around to installing the mobo and CPU this weekend. Decided to add Vista to the mix as well, but I have a small problem. I can't get the audio driver to load. The Device Manager shows HDMI audio, which is the one from the 3870X2. When I manually try to install the audio drivers, I get the yellow exclamation mark in the Device Manager and it says the device cannot start. If I click on "find solutions," nothing comes up.

I tried to install from the driver CD and the DL file on the DFI website. I get 6 or 8 entries to choose from when I install the device manually. Anybody else have this??
