GIGABYTE Z77X Owners/Discussion/Information/Support Thread and Club (UD5H, UD3H, D3H, and ALL) - Page 364

Hi all,

 

Windows 7 x64 SP1 Ultimate 

 

I just got a Z77X-UP5, which looks lovely. Sadly, it hangs just before the welcome screen. I tracked it down to the official HD4000 drivers. Without the HD4000 drivers installed, it works fine (safe mode as well). When loading HD4000 drivers, it loads right up to the point where the welcome screen should appear and then it hangs on a black screen; num lock is lit and stuck.

 

I tried two versions of the HD4000 drivers: 15.28.2.64.2817 (latest from Intel) and 15.26.9.64.2712 (latest from Gigabyte)

 

I also tried two BIOS versions: F4 (came with the board) and F10 (latest from Gigabyte)

 

I also did a fresh Win 7 x64 install. It worked fne until I installed the HD4000 drivers, after which it did exactly the same as above.

 

Anyone had this issue and has any tips for me or should I RMA the board?

 

Cheers

 

p.s. I tried until now a Gigabyte Z77X-UD3H, Z77X-UD5H and an Asus Maximus V Gene ... no such problems as above on any of these 3 boards.

BTW, that's also 3 identical motherboards as well. (2 x UD5H, 1 x UD5H Wifi)
yes, it confirms my suspicion that whatever the problem is pushing up the offset to +.15 or greater is not it!

Well at least I am 100% solid with my fixed vcore. At some point I will experiment with some other settings - maybe PWM Phase Control. If I ever get it solid with an offset I will report back!

I just keep the phase set at extreme performance. Does it make a difference? I don't know to be honest but I suspect not unless you're going really cold. There's really not a whole lot that needs tweaking on these boards for a straight up OC in my opinion.
DVID & LLC, and I set vcore response to Fast, phase Extreme Performance, Profile 1 for my ram, that's about it. Most everything else on Auto. But by all means tinker and learn!

Provisionally, eXm Perf for PWM Phase Control seems to be the key.

I am now using:

PWM Phase Control: eXm Perf
Vcore LLC: Standard
Vcore offset: +0.07

I have managed to switch in and out of sleep 20 times without issue. Switching PWM Phase Control to Auto & High Perf each caused a lock up within 2 attempts at sleep.

Looks solid. But only a few days will tell. Yet to run an extended Prime95 test again as well of course. Vcore at load is a couple of notches down on its level when vcore was set at 1.26 fixed (1.236 in CPU-Z, LLC: Turbo), but 1 hour of Prime was good. Temps of course are better - max core only 58C at load. Will test overnight tonight.

There you go. I can't always remember why I do stuff but I've set mine for Ex Perf since early days with the board. Acute CRS condition......
post #3636 of 6656
i am at 4.4 ghz. multiplier 44x and bclk 100mhz. pwm set to mid power and llc medium. cpu vtt standard. vcore normal with 0.02 offset. max temp of hottest core is 77° measured with real temp under linx stress test. if i use pwm extreme performance the temps are nearly the same and with cinebench 11.5 the score change by 8.60 to 8.90. i dont't understand if exist a real improvement or there is only a waste of electric energy ..
post #3637 of 6656
Actually still not 100% using an offset voltage, so I give up.

Interesting stats though using HWiNFO64:

- CPU power usage under full load (Prime95): 72W
- CPU usage when idle with FIXED 1.26v vCore: 8.5W

So, what am I going to save by trying to get a variable vCore working? 4W maybe, if I'm lucky? I've probably wasted a lifetime of any such savings on this PC just doing the additional stress testing! rolleyes.gif

I am going to stick with a fixed voltage.

Can the last Z77X-UD3H's PCIe slot be used by a PCIe x1 sound card like X-Fi TiHD? This slot physically is x16 but electrically it is x4.
post #3639 of 6656
My UD3H finally arrived today. Now I probably have to wait until monday for my 3570k and ram, and with armored kill and black mesa releasing the anticipation is killer!

One thing I was wondering is, I am going to use crossfire 7970s. Do I really have to use that sata power thing for extra power? Are the 6 and 8 pin cables as well as PCI E lanes not enough? lol

Hello,

I'm on the fence with choosing between the Z77X-D3H and Z77X-UD5H

My current build:
CPU: I7-3770K
Cooler: Noctua NH-D14
PSU: SeaSonic X760W Gold Modular
GPU: Gigabyte GTX 670 N670OC-2GD
Storage: SSD CrucialM4128GB + HDD WD 1TB

I'm going to get the i7-3770K and I want to have a moderate OC of 4.2Ghz-4.5Ghz.
Now initially I wanted to get the UD3H but it's out of stock and would take longer than I can wait so I need to choose between the UD5H and the D3H.

For my use would you say the D3H would suffice? would it hold long term?
I feel like the UD5H is overkill as I won't have use for the extra ports anyway and it's more expensive.
What do you suggest?
