Does Memory Bandwidth booster does anything? and i can't find vcore offset :\ is it hidden?

Not that I've found.

From link in my previous post:

"Note that on the ROG boards; Phase Control needs to be set/changed from Extreme to either Standard, Optimized or Manual in order for Offset Mode to become available in the CPU Voltage menu."

thanks mate for this

Guys did you notice that when u enable C1E and EIST AI SUITE becomes so slower that wont run and keeps freezing, also process Atek...runing at 14% CPU, try that i just did it twice to confirm before posting this...

cheers to all

nope at least not in any of the prior bios that I have tested

Hmmm EIST and C1E are enabled for me, and ai suite is working fine..

yeah i was with all C states enabled and happened now i only enabled EIST and C1E and all is fine...dunno why if i enable the others AI gets slow

but AI is a little bit slow.. u r right, but i have not tested AI with c-states disabled.

[Martin.v.r]

all c-states disabled here
Watercooling on cpu

I think you should have used red dye in the water. The blue (antifreeze?) in the water just (only just) takes away that, prize winning, styling ambience of your finished rig .

Someone experience troubles with gpu fan stuck on stock speeds. Need to activate the auto function in evga precision or msi afterburner but whatever i do the settings reset everytime pc reboots.
Did not have this issue with evga classified. Running 2 x GTX480.

It didn't appear to do anything to my system, not sure if it tweaked any sub-timing or something (I only tried it once), but I didn't notice any differences with it on/off between a couple benchmarks.

it only happens when u enable ALL C states, if you only use C1E and EIST no problem at all just tested 3 times

hmm, so is there a conclusion here? Would we not enable all C States?


Also, I was advised to disable "High Precision Timer" to help with latency.

Is this generally what everyone else does?

[deachus]

Hmm, I am having no issues but don't rember exactly all Cstate settings I have enabled. Will check when I get home and post back. Heading down to MicroCenter now to see if they have any good batches to buy. Hopefully I come back with a good one!

[MonsterDK]

If you read this guide on ROG Forums for offset voltage (same place as guide you posted above) it states you enable offset voltage, then need to boot into windows and look at voltage reported by CPUZ ROG edition at load. Then you use the (+) or (-) offset to raise or reduce the voltage to get it as close as possible or dead on your known 5Ghz stable vcore (or whatever speed your running). The 1.62v was the voltage automatically set by bios so I used the (-) offset to bring it down from 1.62vcore to my required vcore of 1.49vcore (I know, bad chip and I still havent found a good one) which is a setting of (-) 0.13 (1.62 - 0.13 = 1.49vcore)

I still don't have it 100% figured out but like I said, I'm making progress. I believe my problem now is my idle voltage is unstable because the stock idle vcore at 1600Mhz is 1.00v where the offset of (-) 0.13 to be stable at 5Ghz now gives me a idle vcore of 0.87 (1.00v - 0.13 = 0.87vcore) which I believe isnt enough. Remeber, the amount you add or remove will apply to both idle and load vcore so you need to find the perfect medium I believe.

I still dont understand how the MB or CPU determines the starting vcore (1.62v) to start off with and that is what I am trying to figure out. You can select 3 different settings to enable offset vcore, "Manual" "Standard" and "Optimized".

Back to testing

hmm,, so what's the difference from setting 1.62v in BIOS to using AUTO and the offset of -0.13v?

I've read the thread over at ROG forums, and if we are setting the voltage near as dammit to a stable clocked chip then what is the difference to running the voltage on AUTO = default voltage then applying the offset to achieve what you can manually set?
I know there has to be some common sense there some where, someone able to explain this please?

well i just tested again and enabling all C states and puting to no limit C1E + EIST + C2 - C6 etc AI becomes slow really bad, with C1E + EIST not, im on BIOS 1409 maybe its that dunno

[Splave]

CPU PLL to 1.7v... ok cool thanks for replying!
... anyone else have any advise or tips for these settings?

I use 1.53 with no problems even at x54

Hiya!

Are you able to test with 1850?

AS I've not seen that on 1850

[Sauron_Vie]

I use 1.53 with no problems even at x54

yea.. but ur chip is magic

@sergio: will test AI without C1 & EIST... and btw i am using all C-states

[Sauron_Vie]

@sergio: disabling c-states and eist brings only a minimal better loading perf from AI @ my 1st sys... btw. there is no difference in loading AI between my 1st and 2nd sys... no matter enabling or disabling c-states

[i_max2k2]

Could someone who has significantly reduced their overall voltage/load temps from the intial overclock please post their settings. This way others can compare and possibly deduce even better settings. With the plethora of settings in the bios, its kind of difficult to play with all of them.

Thanks!

If I understand what your asking, you want to know why use offset vcore vs just manually setting the vcore?

Ok, lets say you are using a 24/7 clock speed of 5Ghz that is LinX stable at 1.45vcore. The reason offset vcore is good is because if you enable cstate, speedstep and use offset vcore your processor speed at full load will be 5000Mhz at or damn close to 1.45vcore but if you setup offset vcore correctly when your processor is idle it will drop speed to 1600Mhz and will drop vcore to 1.00vcore or close to that depending on your offset therefore reducing temps and power usage when pc is not being loaded or in use. When you run a 5000Mhz 24/7 speed with 1.45vcore manually set not using offset vcore your processor will still run 5000Mhz at full load and drop to 1600Mhz at idle but your vcore will always stay at 1.45vcore at both full load and idle, so vcore doesn't dynamically adjust with CPU speed like when using offset vcore.

Hope I answered your question without going to in depth.

sorry to break the consistency of the thread, but just got my open box MIVE (first ob purchase ever)
It looks like it came in retail package with all the accessories, also checked with asus and warranty is good til may 16,2014 Anyone here ever purchase their MIVE OB... how was it?

Now all i need is for my chiller to come in the mail
