Gigabyte P67/Z68 boot cycling problem - Page 36

post #351 of 811
I didn't gather that it was when the machine POSTed. It's related to settings in the BIOS and/or RAM compatibility issues OR PSU that's gone bad. Check each rail for voltage fluctuations. Do you set your voltages, times etc manually or do you use auto?

These setting can cause issues if not disabled manually. Auto setting will not do!

Disable "CPU PLL Overvoltage" and if you need it for overclocking bump voltage MANUALY
Disable "Performance Enhance" as it arbitrarily applies an OC to RAM for benchmark spiking for review sites... it's a horrible setting that should always be disabled.

I personally enable HPET with 64 bit tables though some suggest it can cause issues with certain older 32bit hardware drivers.

Then set your timings and voltage for RAM MANUALLY!

The reason your customers didn't have this issue with the same boards is because I bet you used DDR3-1066 or DDR-1333 NOT the HIGHEND DDR-1833 or above stuff you have in your machine. In a lot, if not most instances if you use ram of that speed or higher you have to set all it's timings and voltage manually. It's not ID-10T proof with the "Auto" setting. If you own a shop surely you know how to set it all manually and don't need to rely on the luddite "auto" setting!

Nugzo now that I've read all your posts with particular attention I figure the memory controller could be damaged in the CPU from radical OCs and VCCIO voltage and mem voltage difference in excess of 0.05 or greater.

I'll bet money you used very high clock and HIGH VOLTAGE MEMORY!!!

I wouldn't use memory I could run at 1.6 or LESS voltage. 1.65 IMHO will cause issues in the long term unless you up VCCIO/VCCSA SLIGHTLY. The memory controller voltage and RAM voltage should be within 0.5 Intel design spec called for it to be 0.9 and board makers ship at 1.0 or 1.1v That would mean to spec you should use RAM with a voltage not over 1.6 and running say 1.65 or greater with four sticks will surely damage the Sandy Bridge memory controller as you now know!!!

my memory voltage is recommended 1.65v. I keep 1.5v ddr3 at home so i can post and set proper mem voltages...sometimes 1.65v mem wont post on auto with 1.5v stock voltage after cmos reset. My memory is on the compatible list for this motherboard, it worked flawless without BSOD for many months. Bios settings have been reset..by pushing the clr cmos button and by removing battery. I have Patriot 1.5v ram, OCZ 1.75v and mushkinl 1.65v ram and none will post now. I use a combination of auto and manual for mem timings. When using 16gb or 24gb i normally drop the speed and loosen the timings for initial setup, tweak till everything is stable, then start upping it to profile settings, then beyond if substantial performance gains are possibe.. but with 24gb at 1333 vs 1600, there isnt much of a performance gain...atleast not in benchmarks. for example if the mem is rated 1600mhz 8-8-8-18, i may start off with 1333mhz 9-9-9-24. Not sure if this is necessary but its how i've done it for years, never let me down. I only do this with large amounts of ram. If only 8gb i start at profile speeds and timings.... Its a lot harder to tighten 24gb than it is for 8gb... obviously

this is very possible, we will see tuesday when my new ASUS Maximus IV extreme Z board arrives. Using all my same parts (16gb mushkin redline pc3-17000 9-11-10-28 1.65v, 2xGTX480, 1200watt Antec PSU, 2 samsung 128gb SSD Raid 0, 2x1tb Seagate 7200rpm, Raid 0, Plextor Bluray, Watercooled 3x120 rad, 1/2" ID Tygon tubing, Dual MCP355 pumps, only CPU in loop. 2600k CPU (48x100) 4.8GHz at 1.365v. 24/7 settings. Can bench at 5.2ghz and game but it needs 1.45v for soso stability. at 4.8 though i've never had hiccup..thats with HT enabled, great chip IMHO.

Nugzo - which Z68 board do you have? I'm still undecided on keeping this Z68X-UD4 and i5 2500K that I have. Neither has even been out of their boxes. This build is for a work machine and I absolutely can not afford to have any issues with it.

z68x-ud7. After unplugging and removing cmos battery overnight it booted right up this morning with no problems. It did the same way day before yesterday, but going to sleep caused the boot cycle again... disabled sleep, now maybe it'll work long enough for my asus to arrive...

Are you using a sandforce SSD by any chance? I have read that they cause issues with some of the Intel boards.

1. Do NOT recommend people get another brand of motherboard, that is first and foremost because I have used Gigabyte, Asus, Asrock and MSI and they all have this problem.

2. This problem is NOT a manufacturer problem from what I can tell, in my 30 motherboards of testing I have found that only one ( Asus P8Z68 Deluxe and only by sheer luck ) gave me any information and that information was the boot loop into memok reset into Code 78 Indicating what I thought all along was the problem, ACPI. This is a chipset issue, it wasn't right the first time and its not right now, Intel fubar'ed this one.

3. I have NOT found a resolve for this, once it does it the loop will never go away perfectly, I have updated bios', installed 1 - 3 GTX 580's, 1-2 GTX 590's, 1-2 6950's/6970's almost every configuration and brand of memory, SSD, video card and more and nothing makes a difference. I have also changed or ( for the guy mentioning disabling the Marvel chipset ) disabled every and I mean EVERY single type of hardware setting inside the bios' in an attempt to fix this and nothing. The last build the Asus Deluxe all the ACPI options inside the APM section were disabled Fyi so the hardware attempting to use it seems ridiculous in the first place.


Any questions about what all I have or have not tested just ask, but its basically everything, still willing to listen to suggestions for setups/what to check further to find the solution, but I would bet the solution is to tell Intel where to stick this chipset.


As another fyi I should have known months ago when I started this that the fact that I can't put my computer to sleep and have it wake up without a total reboot should have clued me in.


C
I own an Asus p8p67 deluxe and have not once experienced the problems described in this thread.

Initially I did have problems with my ram, everytime I reset CMOS I have to use the memok button to get it to boot properly then I have to manually adjust the bclk down to 100 and enter my ram settings. My ram is not officially supported by this board and I think that may be why.

That being said, I never have to reset my CMOS so this does not pose a problem. Other than that this board has worked flawlessly. It boots the first try everytime, with or without mild overclock, or extreme overclock.

So in response to your statement, I do believe this problem is mfg specific. I have owned a couple gigabyte boards and I know my p55 board had a boot cycle problem. I ended up having to rma the board. Gigabyte sent it back to me (with a reflashed bios I assume) and it has worked flawlessly ever since. Im not saying all gigabyte boards are bad, but I am saying that almost every gigabyte board that has this problem has a main bios and a backup bios. I think they have been struggling with this problem ever since they started putting 2 bios on there boards.

Some asus boards have had problems like this too, just not mine and not on the same scale as gigabyte boards.


edit: sorry, this wasnt supposed to be a second post, but rather a edit to my post above. (tapatalk) =/
