GA-X58A-UD5 cool boot BSOD

[bollitori]

6 months ago built a new system with Gigabyte GA-X58A-UD5.

Gigabyte GA-X58A-UD5 Rev 1 - Bios F7E
Intel i7-930 Bloomfield 2.80GHz LGA 1366 D0
Noctua NH-D14
6 GB DDR3 2000 (3x2GB) G. Skill F3-16000CL9T Trident 2000-6GBTD 9-9-9-24@1.6v
Sapphire Radeon HD 5870 1GB GDDR5 256-bit Video Card
Corsair HX Series 1000W Power
WD Caviar Black 1TB SATA3 WD1002FAEX
Win 7 Ultimate - 64bit

From the beginning I had problems with the PC cold start, producing continuous BSOD, which disappears after 4 or 5 reboots.

After these restarts the system runs stably.

I tested the memory with memtest86 + 4.10
- In a cold start --> infinity of memory errors.
- After several restarts -->  No error in memory.

I have also found that even when "hot"when the PC has achieved a stable performance, if I turn off the PC, disconnect from the mains for 30 seconds and then reconnect the plug from the wall, and I start the PC run the memtest86 and test again to continuous errors ...

As I have read in some forums the problem may be in the X58 chipset.
Is a possible RMA.

This is desperate  , you can help.

This is a problem that does seem to happen to some boards. I don't really think it is the X58 chipset that causes it although it might be a contributing factor when installed alongside something else.

Is your memory on the QVL for this motherboard?

What speed are you trying to run it at?

[bollitori]

Hi Dark Mantis, thanks for reply

Yes, this memory QVL listed

I am using the 2000 MHz XMP mode (profile1)

Although the case with the speed of 1066 Mhz

I tested with memtest86:
- each DIMM in Bank 1 --> 0 errors.
- With 2 DIMMs in bank 1 and 3 (Dual Channel) --> 0 errors.
- Triple channel errors --> begin errors.

This is what I have been able to detect today.

[Dark Mantis]

I didn't quite understand at what speed they are presently running?

You will need to enter the settings/voltages manually to get anything near that rated speed and even then problably not all the way there but certainly closer and maybe even tighten the timings a little instead.

Hello,

2.8 GHz CPU running
BCLK 143 (Auto) profile1
RAM - profile1 2000 MHz 9-9-9-24 XMP mode (Auto)

In other previous tests, I have also manually latencies, and similarly. This is so mad with so many tests I've done.

What QPI/Vtt are you setting, and what memory multi and uncore multi is being used?

For 2000Mhz memory you will need at least 1.4-1.45 QPI/Vtt, many CPU's will often need more than that just to run 2000Mhz (1.45-1.5+)

QPI/Vtt [Auto] 1.2 --> ET6 shows 1,54
Memory multi [Âuto] orders mode Profile1 XMP

Attached captures CPU Tweaker and ET6 voltage

[Dark Mantis]

From your screenshots I would say your uncore is way too high at 28 it should be twice your memory multiplier + 0-2.

So a memory multiplier of 8 should give you an uncore setting of 16-18 and 7 would give you 14-16

You could also try loosening up your memory timings too try 9-9-9-27

you could also up the voltage of the memory to 1.66V

[Lsdmeasap]

For sure, lower that uncore and you might be perfect!   And then you may be able to lower QPI/Vtt, maybe not though at those speeds.

Also, 1.36 IOH is way to much.   Try 1.1-1.14 should be plenty for 2000Mhz and your Bclk.

also enable EuP in power settings in bios, i have this enabled at moment i have a cold boot issue, not had one since i enabled it, but i am default settings and Xmp profile, next test is overclcok.

 

i read somewhere enabling EuP helps the Ioh as this drops if EuP is disabled and can cause Cold boot problems.

[Lsdmeasap]

Interesting, thanks for the info on that!

I always suggest users to disable this if they are using it because it often causes issues with S3 resume for many users

[Dark Mantis]

It is suprising how many problems can be laiod at the feet of the Power savings settings.

"SAVE THE EARTH SCREW YOUR SYSTEM" should be the proper name for them.

your on this thread mate, but is hard to keep track if your not on allot i only fell on it myself  post 1040-1063 http://www.xtremesystems.org/forums/showthread.php?t=240276&page=42

S3 resume? is that boot loop at cold boot?

the power saving stuff seems to kill Psu's after a while as well, been googlng this C1,eist state ect for a few days, x58 and all brands issue i am leaving the save the monkeys off from now on.

might drop the v-core down a bit though..

[Dark Mantis]

I don't use them much anyway as I use watercooling and prefer to have everything running steady all the time. I just set the monitors to switch off etc when not in use. They do cause a lot of problems with several components though for people who do use them.
