GA-Z68XP-UD4 - Page 2

post #11 of 18
Direkt - Noticed the same thing on my UD4. When changing voltage control to "normal", and then using DVID the option to change Multi-Load Line Calibration greys out. However, it appears that you can still enable LLC using the TouchBios utility from within Windows. I have confirmed that if you set a LLC value in TouchBios that the new value you set will also be the real value shown in the BIOS. Last week I got a stable 4.5Ghz setup (Prime95 12 hours and a bunch of BF3 hours) running x45 CPU Ratio, "Normal" cpu voltage, DVID of +.04 and LLC 4. All power saving features EXCEPT C3/C6 sleep states were enabled.

Everything was great and I went about tweaking using DVID at x46 CPU Ratio. Got another 12 hour stable setup (using +.08 offset this time). After that things went to hell in a hand basket. Found out that while Windows sleep (not hibernate) works great at 4.5Ghz, it didn't work so great at 4.6Ghz. My PC went to sleep and when I attempted to wake it back up everything froze. Repeated the same scenario three times, and after each failed attempt got the nasty BIOS warning that overclocking had failed due to voltage or frequency changes. And, for some reason no attempt to reapply my saved profiles would work unless I did a full CMOS reset.

Accordingly my initial plan of confirming that LLC was indeed working with DVID via hard measurement check points with my digital MM have been put on the back burner until I can get stable again. I've seen a ton of folks that have been able to get 4.5Ghz and higher overclocks at reasonable voltages and without running any LLC. Unfortunately I haven't been able to do the same. For some reason (either my particular board or cpu) once I hit 4.5Ghz I've got to use LLC of 4 or 5 to stay stable and eliminate some fairly disappointing vdrop and vdroop. I've got a good power supply - Corsair HX1000 - and all of my other hardware is top notch too.

I'm using bios version F6 - and personally I think that might be the difference between earlier reviews of our (and similar GB boards). Supposedly all of the latest P67/Z68 bios revisions have been tweaked for the new IB processors. I'd revert back to an earlier revision BIOS but am afraid of getting stuck with the infinite boot loop issues that seemed prevalent back then. If you'd like I can start exchanging BIOS settings with you and maybe between the two of us we can come up with optimized settings.

That is very interesting! I'll try that trick out and see if it works for me! Have you tried enabling internal PLL overvoltage? That seems to be a favorite trick to squeeze an extra multi in.

Update....
Since I was starting from scratch I combined some of the old and some of the new and came out with 4.6Ghz stable using DVID and no LLC set via TouchBios. First off came a full CMOS reset. Secondly, loaded optimized defaults and set all of my RAID and other hard drive parameters.

Memory frequency settings - did not use the XMP profile. Manually set my four primary timings and command rate and let the BIOS do the rest without any XMP Profile
At stock clocks and voltages changed my cpu voltage from Auto to Normal. Resulting BIOS set value for vcore was 1.240 with actual of 1.224
Set CPU Clock Ratio to x46 and BIOS changed stock VID to 1.345 upon reboot
Added +.06 to DVID which worked out to 1.38v actual vcore after reboot
Changed CPU PLL voltage to 1.76v (seems to be a sweet spot for me)
Set QPI/VTT to 1.10v (running 16Gb of DDR3 1866Mhz memory at 9-10-9-28)
Changed Memory Voltage to 1.52v (Auto was 1.50v)
Enabled BCLK control and input 1002 which fixed a 99.80 BLCK issue I was having - change netted a true BCLK of 100.03

Everything else was left on Auto, everything.........

Booted into Windows and ran Prime95 blend for 9.5 hours - pass
Played a couple hours of BF3 - no problems
Ran Vantage and 3DMark 11 twice - no problems

CPU frequency at Idle - 1600Mhz
CPU vcore at Idle - 1.04 > 1.06v

CPU frequency at Load - 4603Mhz
CPU vcore at Load - 1.334v

Based on readings with my digital mm I have to say that using DVID does incorporate some level of Multi Load Line Calibration by default - and probably why the option is greyed out in the BIOS when you choose Normal voltage. For 9.5 hours logging using the OCCT logger there was no voltage fluctuation to the second decimal point. Regular checks with the digital mm confirmed same. Also happy to report that there weren't any recordable (measurable without an Oscilloscope) spikes during the loading and unloading of the cores. Upon loading cpu vcore went from 1.06v > 1.26v > 1.334v and just stayed put from there.

Wevsspot~

Nice to hear I'm not the only one pulling my hair out trying to get DVID to work right. I've gotten booted up at a 47x multi turbo with the VCORE set to "AUTO" that ran P95 for 'bout an hour no errors but CPUID Hardware Monitor showed 1.45v-1.42v regardless of load or RealTemp showing a 1600Mhz @16x multi and a 0.96VID. So I simply set my VCORE to "NORMAL" and bumped my DVID up to I think +0.110 or whatever it took to reflect the same 1.420 vcore in BIOS but once booted, CPUID HM showed a max of 1.36 under load and give me an instant BSOD the second I clicked "GO" in P95. I tried everything and now it seems I have to do a full CLR CMOS everytime I make a change or else it's all funky.

I'm going to try using the Touch Bios like you mentioned and shoot for a stable 4.4Ghz. I had it once but since I upgraded to F6 I think the SVID range has been changed...

I'll post back with full screen shots and results.

I've been having exactly the same problem with my UD4......

I've managed to get 45x multi stable (prime95 11 hours)

intel turbo boost disabled

C1E, C3C6, CPU Thermal, EIST all on AUTO

Memory set on Profile 1 XMP with 1866

Multi Steps load line disabled

vcore set at 1.365 (the default 'normal' is 1.360)

I have all the rest on AUTO

CPU-Z records vcore as 1.380 at Idle and 1.392 at load

Temps stay below 65 at load with H100....

Now that i found the max set voltage, I tried to set vcore to normal and make up the difference using DVID (adjusted so the vcore was the same at boot in the BIOS) no matter what i tried BSOD straight away either when windows starts or prime95....

Would have been good to get stable overclock with vcore dropping when at idle with the clock by using DVID, but i'm about ready to give up....

Here is an alternative to DVID that I have used occasionally, just set LLC right up to 10, then adjust until the load voltage is where you need it, then, it will undervolt considerably when not loaded and be right where you want it when it is! It's not ideal, but it's the best option we have on this board!

Yeah I've been messing and messing with the UD4 and my i7 2600K for a while now and never could get past the 45x multi roadblock with a DVID OC.

I even noticed that after a full CMOS clearing when I put my multi past 45x, VCORE to NORMAL and boosted my DVID to get my volts up to 1.38-1.4~ or so 8o CPUID monitor would show my volts never getting past 1.36 at best.

Frustrated I decided to do this:

CLR CMOS
Load optimized def settings
Set up my raid and other junk the way I need it.
all the rest left to AUTO.....EXCEPT the SYSTEM AGENT VOLTAGE. The auto has it at 0.920 but I read in an Intel document from it's Extreme Tuning Utility that the correct system agent voltage should be 0.925V So I set it to 0.925V
Vcore to Normal
I put my DVID to +0.090V
I set my DRAM timings
Enabled XMP Profile 1, STANDARD and EXPERT

Then I DISABLED the stupid TURBO!
Enabled CPU PLL Overvoltage
Set PWM Freeeek to +6%
Set CPU Over Current Protection to +20%
Set Multi to 47x
Enabled the BCLK and set it to 999
Disabled the Thermal Monitor
Enabled ALL Cores; CPU Multi-Threading; C1E; C3/C6; and EIST

Now my DVID puts my vcore where ever I want it reliably, and all the power saving stuff works as it should. My Vcore goes up to 1.39V under full load and drops to .88~.96V @ 16x multi at idle.

It's PERFECT! I think the TURBO is what's been screwing it up all this time. now my BIOS reports 4.7Ghz @ 1.42V and CPUID reports it never more than 1.39 under full load all 8 threads. I ran Prime 95 for 'bout an hour till my room got too hot to bear and backed it off. Haven't had any issues and haven't had to mess with BIOS in months!

Hopefully my rig is listed correctly here, and an afterthought, please don't use ANY of the utiities from Gigas' site, esp. the DES....if you have the misfortune of getting that installed you may as well strip your drives down buck naked, format and reinstall everything.

Good Luck!
