Asus Z77 Series Information Thread (drivers, BIOSes, overclocking, reviews) **UPDATED 4/22** - Page 22

post #211 of 1288
I've been looking to start a new build soon as my current one is over 4 years old and was looking at these new Z77 boards that Asus is coming out with and I'm not sure if I'm missing something here but why don't the sabertooth or Rog boards have PS/2 plugs on them?

Because about 95% of users don't use or have PS/2 anymore. I think it should be there as well but hey, gotta move on sometime.

My UD5H doesn't have the PS/2 either. I was actually going to use PS/2 for the first time in YEARS with my new mechanical keyboard... but went under the desk to set everything up and was like "whaaaaaaaa?" and had to take the adapter off. Figures, the one time I go to use it, and it doesn't exist anymore tongue.gif

Hi guys

Two questions re: P8Z77-V Pro overclocking:

1) I was under the impression hitting "apply" to settings in TurboV Evo would write them to the UEFI, but when I reboot my OC settings are not there. Anyone know how to make it happen? I'm curious if TurboV Evo is using an offset voltage (I think it is, a positive one since voltage lands on 1.2V when set to 1.165V in TurboV = +0.35 offset) and I want to know what that voltage is, as my ultimate goal is to tune the machine in UEFI to use the lowest BIOS at idle/load as I possibly can.

2) If I now know that I need about 1.2V for stability at load, what would the optimal offset settings be to achieve this (and still maintain lower voltage at idle to save power/heat)? In the Asus Z77 videos they recommend negative offset and regular LLC? Is it a guessing game of booting with auto and seeing what voltage it applies, then running an offset? TurboV doesn't let you touch offset from what I can tell.

Background:

I recently built a new IB system using an Asus P8Z77-V Pro and last night finally got around to playing with the overclock. I used Asus' TurboV Evo software to auto tune it to get a ballpark of what the chip would do, and then manually started lowering the voltage while doing LinX passes.

Ended up settling on 45 x 100 = 4.5GHz with all every setting at default except CPU voltage in TurboV Evo at 1.165V. This effectively results in peak voltage under LinX load at 1.2V, CPU cores peaking at 70/79/74/75. For stability I ran LinX for 5 passes (49m56s 103.67Gflops) and had a 3 hour gaming sessions (2h 64 player BF3, 1h Mass Effect 3). I will run a longer ~20-30 pass LinX test to verify once I nail down final settings.



Thanks!

1) it does not right to UEFI, but you can use it to test and then manually put into bios.
2) I would have said what you said, and experiment until you find the same vcore in cpu-z set as offset in bios as yo uhad through software.

However today I updated my bios, and set everything except the offset (normally -0.01) my voltage at 4.3Ghz was 1.28 vs my normal 1.1V (an apparent offset of -0.18 required).

Testing in software and got back to indications that a -0.01V offset was required, set it and all ok. Its all a bit odd.

Now I don't use any LLC control, I believe that if I did I would have a lower idle voltage at the same load voltage, which would threaten idle stability, whilst providing no real benefit in temps as I am idling at 30-33C.

I am about to upgrade to Asus Z77 & IB 3770K. My problem is this. I have a Corsair 400R case and H100 cooler mounted at the top of the case. I have read that people have had problems with the 8Pin +12V Power cable interfering with fan clearance on the H100. When using Boards with the 8 pin connecter right up to the top of the MB like the Asus P8Z77-V.
The Asus P8Z77-V LE power connector is moved down a tad and might allow for more room.

The question is this: If I plan to overclock the 3770K to 4.4-4.5 GHz range will just having the 6+2 VR on the LE make any difference than having the 8+4 VR on the V?
Ram will either be 2X4G or 2X8G. I will not have all 4 ram slots populated.

Buy the lowest ASUS P8Z77-V LX like me and get the grandfathered tech, it has the combo PS/2 port. Removing the port does kinda suck for hardcore gamers, NKRO is a selling feature for the mech boards, not sure why you'd need to "faceroll" 104 keys, but its nice to know you can ! :-)

PS, I used it the first week I owned the board, but got nervous having the adapter hanging out that extra inch and just caved and plugged the board into the USB.
post #218 of 1288
is there a chart that lists the differences between all the p8z77 models? i tried using the asus website's "compare" feature and it fails consistently, plus it can only do 5 items at a time. i tried neweggs but it can only do 5 at a time.

if there isn't then i guess i can use newegg's

Okay great. Thanks.

There's now a new bios (0703) for the WS board from the Asus website.

The description doesn't really tell me much. Are you able to find any further information on what's in the update?
