2133-2250mhz 7-10-7-27
bclk 100-105.5mhz set in bios
RTL 35,36

[Raja@ASUS]

Thanks. I need more results; various frequencies and CAS please.

[st0ned]

@ 2133 cas 9, 8Gb ripjaws 9-11-9-28

I can only use 38, else then that no boot ( either 39, 40 or lower such as 37 36 )...

@1866 cas 8 ( 8-9-8-24 )

I can only use 35~36, else no boot

[Raja@ASUS]

Thank you. The fact the margin is so tight is actually a good fit for how this all appears to work.

Could you explain what influencies RTL ? I've started with AUTO, see what it goes for and then tweak from there, but I allways end up with no boots

From a user perspective it's only CAS and memory frequency, as you can't control any of the other variables that tie into the sensed value (well, there may be something but it won't help performance anyhow). The main thing here is that the correct value is selected by the IMC out of a two clock margin.

[st0ned]

So we should focus on tweaking the timmings and let the IMC auto choose the correct RTL value ? And get RTL lower wont benefit performance, Have I take the correct conclusions ?

Lower would be faster, but you won't actually be able to move RTL far enough to affect performance in a meaningful way. Intel has already optimized data transfer for performance.

The only thing that is worth noting from this is that there are certain memory frequency and CAS combinations that fall near the edge of a boundary to make a data transfer. This isn't really an issue until you push the system way beyond officially supported memory speeds (DDR3-2000 and upwards), at which point the sensed value might be 1 clock away from a more ideal value to transfer data.

I've moving around with some interesting instability issues and they may have something to do with what you are saying.

I know for sure my CPU does 5Ghz with 1.376v

I can pass wtv amount of LinX run's with him but with mem at 1866 8-9-8-24.

My mems can also make with CPU @ default 9-11-9-28 2133, but the combo, 5Ghz and mems @ 2133 is a no go, I run 2 runs and LinX crashes. With mems @ 1866 I've around 140Gflops, before crashing ( linx error ) with mems @ 2133 I get around 141Gflops ( till now all good ) but, I've tryed to tweak around with vccSA and vccIO giving him 1.16v vccIO will make him run more then 2Linx round ( around 7/8 ) but with sub-par performance around 137 gflops.

In the end I gave up... and use it with 933 mems with lower timmigns... And with 2133 wtv voltage in bios 1.375 // 1.380 till 1.4v it will allways crash @ the 2nd round...

Hi

st0ned > how you can have 5 Ghz with 1.376 V ?

i search to have this setup on my motherboard

Thanks

[aoch88]

Has anyone with 4GB RAM managed to reduce Vcore by upping VCCIO/VCCSA? If you're on 8GB then it makes a difference if you meddle with VCCIO/VCCSA but how about 4GB setups? I tried on mine, no big difference it seems. Vcore hungry chip!

Hi

st0ned > how you can have 5 Ghz with 1.376 V ?

It's almost all about the chip, I got to tweak a bit but that let me drop ~0.015v all the rest is pure chip awesomeness. I never cared about taking a PS of my 5G, but



Few passes.

This is my 5.1 1.416v PS

[fab-45]

Thanks st0ned for your answer ! i see why i can't do that

i have HT on 4 cores 8 threads
4 cores and 4 threads i put 1.38 V and run

i want 5Ghz with HT on . . . if possible, but i have aircooling thermalright silver arrow and it s hot with 1.455V on CPU

Thanks

[st0ned]

HT on wasn't that hard before latest linpack came up ( the one that let was go >100gflops with HT on ) but even that, atleast for me needs 0.015v more then HT off to pass. I can later give it a run. When I tested the new lipack I had to go for 1.424v at 5.1Ghz instead my normal 1.416 for stability.

If you can do the 5 with HT off @ 1.38v ( take 25 run PS for proof ) you should do it with HT on at around 1.4v no more then that. HT aint that big hit for SB as it was fore 1st gen i7. My chip goes for the same temps with HT or without it and it gives me ~+2W ( by hardware monitor ).

EDIT:

Proof for it

Indeed true, as I like to test everything by myself I went out for some tests.

Ambient temp were 21ºC. I had the AC on so ambient temp didn't change.

OPT1 = Temp from the last Rad [TPA120.3]
Water temp in the res ( It's after the CPU OUT ) = 23~24ºC

Cooling is made by a costum WC setup:

Feser Xchanger 360
TPA120.3
Swiftech 655

The rads are in a cake, like
[fans push][Xchange][fans2][TPA][fans pull]

push/pull by Enermax Magma(69CFM) , fans2 are the TFC midspeed (1800rpm ~88CFM).

Old Linx (==New Linx ) with no HT runing in 4T, voltage 1.408~1.416v

~141w


New Linx with HT , 8T, voltage 1.424~1.432v

~143w







Desclaimer: I had to bump the volts from 1.420v to 1.44v ( in bios ) in order to run HT on without freezes/BSOD. 1.420v freezed after few seconds, 1.435 BSOD after the 2nd run. Also keep in mind that I'vent yet been working in to optimizations for HT on voltages, so what did was just work the vCore out until I got it stable, more can be done to bring vCore to around 1.435 at least, I'm sure.

I have something called GPUTweakit and RC Tweakit on my desktop. When i click on GPUTweakit the program starts up and shows up in the taskbar. When i right-click on it i can only choose about and exit...about says something about GPUTweakit server 1.00.10 and thats it. What is this software doing actually. I guess it has something to do with the Graphics card or?
And when i click on the RC Tweakit it says: The connection is not available...What is this program doing???

[st0ned]

Those should be installed in a "server" computer, then you connect that computer to yours with the USB cable provided with the MB , any USB port in the "server" PC and ther ROG port in your "slave" PC ( ROG port is the only one in vertical position ) with that you can change settings ( OC stuff ) using the "serveR/master" to control the "slave" on

[gjeewaytee]

Aha....Thx st0ned

[fab-45]

hi

st0ned > i can't run 5Ghz HT on at 1.41V

under 1.455V = bug for me

i put 350Mhz at VRM frequency is it good ?
and Vcore over current protection = 150

bios : 1298

Thanks

[fab-45]

i test with a new bios 1485 and 1.43V CPU

4 cores and HT ON 8 threads just to see

and GFlops are very little !

YOu ain't using latest linpack that's why, with that old linpack 4C8T it's easier then 4C4T.

There is no difference in LinX performance between 1485 and previous BIOS releases.

[Mason@ASUS]

MASON@ASUS what is the correct driver to use on this board running on the Intel SATAIII for a OCZ Vertex 3 drive?

10.1.0.1008 drivers work fine. You can use the ones from the disc, from our support website, or from Intel.

[fab-45]

Thanks for your help st0ned and Praz

but for my setup in bios ...

VRM frequency (350) and Vcore over current protection (150) is good ?

Thanks

[YoooH]

need good config for my m4e, please advise me which function should I disable?

Thanks in advance.

Funny Problem,

If I use updated Intel drivers I get freezing when I use Internet Explorer ect.
Tried this 3 times with fresh Windows 7 64bit.
If I install from Asus disk no problems.

No Microsoft Updates were applied.

This is were it gets funny, I'm running triple sli & when i install windows explorer 9 I get higher video card temps hitting over 60c just browsing the net. I have no clue why this is going on but if I leave explorer 8 installed my temps are around 40c.
