new system - ASRock Z270 MOBO giving error A2 (Solved)


Best Answer tigger3370 , 04 May 2017 - 06:20 PM

Tested the USB stick in the UEFI and it worked. Got a screenshot. Set the water pump to water pump and left it at whatever it was for power. In the fan set-up and test, it choose to run it at 100%... Go to the full post »

I missed hitting the attach this file button. Both the SPD and memory screen shots are now attached.

 

Where's the link for HWMonitor? Did i miss it in an earlier e-mail?

 

When I do this:

With the MB XMP switch to on.

Power on, > enter UEFI, > OC Tweaker  screen.

On the left, > select  Dram Configuration, > click XMP, Select the profile that matches your RAM, > go to exit, Save Changes,  

 

I can't get it to boot. It just stops at the 3F error code and I have to wipe the CMOS again. I'll try it again but it is trying...

i missed adding HWMonitor link.   Temps/fans look good, some volts not shwing, nt unusual for software like this.

I don't have your board, only just found a link with decent explanation of the UEFI.

Next time you get a no Boot, try, restart, enter UEFI, > Load UEFI Defaults.

 

Try again, this time with the XMP switch off.

OC Tweaker  screen.

On the left, > select  Dram Configuration, > click XMP, Select the profile that matches your RAM, > go to exit, Save Changes, 

 

In this review, shows setting for overclocking.   Have I missed something in giving instructions.

The problem when I don't get a boot is that I can't even get to the UEFI screen without clearing the CMOS. :(

 

I'll try the other thing now. EDIT: Tried it.

 

Attaching the old and new (memory2) screenshots of the CPU-Z Memory tabs. I do notice a change in the Frequency. Tell me that means it's working... No change on the SPD tab.

The NB frequency is the CPU, not RAM.   The SPD able does not change, only lists what is available.

Unfortunately still not working.

 

Although the MB QVL does list tested RAM @ 3738MHz, Your MB on the G.Skill QVL only list fastest tested RAM @ 3600MHz/

http://www.gskill.co...-3600c17d-16gtz

http://www.gskill.co...2859&model=2882

 

You can attempt some manual settings but, enabling XMP on your MB and The memory controller in your CPU (IMC) may be unreachable without altering one or more voltage values.

Please write down the following instructions or print them.

Dram frequency  3733MHz

Cas latency 17.0

Ras to Cas Delay 18

Ras Precharge 18

Cycle time 38.

1.35 volts.

 

With the XMP MB switch off.

Go UEFI, > Dram Tweaker Screen.

If you click on the Dram Tweaker, do you get similar screen with your XMP on the right? ? >

Since I'm not home, I don't know the exact screen, but I know I get a screen that looks something like that. In the easy view, if I click on my memory, I get similar columns. Wish I was home so I could tell you what the values are. I want to say that the xmp 1 column on mine shows the the correct number for the Frequency, and I think the voltage is listed as 1.35 volts, but I can't remember the rest of the numbers. I'll have to wait until I get home to check them all out.

 

EDIT: Should I update the BIOS to 2.0? It only mentions that it's for the new Intel Optane Memory.

I'm home now and here are two pictures I took of the BIOS screens. The one on the left is from the OC Tweaker screen and the one on the right is from the Easy Layout Screen of the BIOS.

 

EDIT: Changed the XMP to on and XMP 1 and it booted, after getting the 3F once or twice. Found out, I get that error anyway and just have to shut off the power supply and try again. How can I tell if the XMP settings are working?

 

Second EDIT: Clicked on all the settings in the column under the easy screen for the XMP. Then, went to the advance OC Tweaker screen and change the Frequency to 3733, Cas latency to 17.0, 

Ras Precharge to 18, Cycle time to 38, no place to change the voltage to 1.35 volts. Looked at changing the Ras to Cas Delay to 18, but there were two and the maximum value allowed was 15. Possibly getting closer as the DRAM Frequency on the Memory tab went from 1076 to 1867 and the FSB:DRAM ratio went from 1:16 to 1:28.

 

Third EDIT: I'll check again later, but I think I boot up without the 3F error anymore. Update: Just rebooted without any issues. Yay! I less problem.

Well done, if you are booting without error, looks to be OK.

 

The screen on the left show s jedec #1, 2133MHz.

The screen on the right just shows what is available.

The CPU-Z shows memory as running tras at 38 instead of 37, but Dram frequency 1866.8  x 2 = 3733,6MHz. is a fraction over, but if it runs good, than that's OK. 

 

 

EDIT: Should I update the BIOS to 2.0? It only mentions that it's for the new Intel Optane Memory.

Not at the moment.   Updates should be done if it address an issue, or enhances the overall performance 

 

How quiet,/noisy is it running?   Any other issues at the moment?  

Please enter UEFI, make sure EZ mode is displayed, upload a screenshot,  so I can have a look at all the current setting, 

Can you read up from your manua, about saving UEFI profiles.

we will need to do a little testing to make sure it is stable.

Actually, the advanced view shows the settings and I'm attaching it. I made the change to the tRAS to make it 37 instead of 38. No issues after the change.

 

Fans seems to be running at the same speed as before. Compared the temps using HWMonitor and they are very similar. Memory is maybe a degree Fahrenheit higher, but that's about it. I'll look into how to save the UEFI profile. Not in the manual I have but I'll see if the one on their site has more info.

OK, that looks good.

Would like a shot , Main Screen, in EZ mode, that shows nearly every setting.

This is the EZ mode screen. Is it what you were looking for?

Great :spoton:  Temps look very good, memory good.

Tip.   With a Fat32 formatted USB stick in a USB 2.0 port,  pressing F12 will take a pic of any UEFI screen and save it to the USB stick. 

 

Let me know how you get on with saving the current UEFI profile.

Good to know about the screen shot, although, I don't think I have any USB 2.0 ports. Looking through the manual, I've found a spot called "Save User UEFI Setup Profile to Disk" at the bottom of the main OC Tweaker Page. I'll have to verify that it exists on mine, but should be good to go. I should also have the advanced turbo function since I have a K chip.

 

EDIT: Went through and read the manual. Going to go in and make sure the CPU_OPT/W_PUMP is set to water pump in the UEFI and set locations (sources) for all the fans. Also going to look into the F-Stream settings and check out the info and my things in there. Any opinion on Creative SoundBlaster Cinema3? I'm going to install and play with it as well.

 

Second EDIT: Made CPU_OPT/W_PUMP change and going to mess around some more with F-Stream since the fan setting program looks just like the UEFI program.

When in the UEFI/BIOS not all USB ports may not work.   Usually the top two ports on the MB function.   As yours are USB 3.0, a USB 2.0 stick will work.

I have had very little luck in finding precise instruction for connection the water pump plug.   Opinions seem to be, whatever port used should be set to DCv.   On some MBs, the Opt.CPU/water header has controls for both functions.

 

Can't help with Sound Blaster as all I use are basic headphones.

 

When setting, up case fans, try to have higher intake flow to achieve some posative case pressure.

 

Run HWMonitor for temps, when finished and compare to your in Reply #18

Tested the USB stick in the UEFI and it worked. Got a screenshot. Set the water pump to water pump and left it at whatever it was for power. In the fan set-up and test, it choose to run it at 100% all the time, which should just be fine. 

 

Temps look good. Tweaked the input fans to be just higher than the output fan. I guess with three fans in (two case and one radiator) and only one out, more air should be coming in than out. Nothing else to report.
