BIOS loading settings after power off

[Gavpedz]

Hi I am hoping someone might be able to help.

 

Basically i updated my rog strix b450-f motherboard with the latest bios 4402 (wish I hadn't!) since then every time there is no power to the PC (power cable detached or mains plug switched off) it forgets the bios settings. 

 

Just shutting down the pc is fine as long as I don't cut all power. I have replaced the mobo battery with a brand new one and that didn't help.

 

Also the only way to get post after removing power is to remove one of my ram 8gb Corsair sticks otherwise boot gets stuck cycling through ram. 

 

Once booted with one stick of ram (doesn't matter which stick or which socket) I have to go into bios and set D.O.C.P standard to on, save and shutdown then add my other stick of ram again.

 

After that all runs perfectly until there is no power again. I can shutdown and startup no problem it is only when there is no mains power at all. 

 

Time is remembered in the bios as well so I and really stuck. All components are new and only about 5 months old. Power supply is 700w.

 

So what is it that is making the BIOS forget settings when no power? It was absolutely fine with no issues until I updated. I was on 4007 but cant even go back to that version apparently!

How do you run your Ram, stock timings ?

Maybe your new bios can't handle them and resets everything.

Ok, this doesn't make sense.

But still, how do you run your Ram ?

 

Edit : There usually is a way to roll back bios

[Gavpedz]

Yeah this is the odd thing I can't roll back to any other bios version but not the one I was originally on. 

 

I don't overclock although I think setting the D.C.O.P may adjust some settings. 

 

I tried just setting defaults and not touching anything on the bios with everything auto but then I can't get post with both sticks of RAM. It seems I have to have D.C.O.P standard on to be able to run both sticks.

It'd be nice to try some other Ram

Do both sticks behave same ?

Did your try different slots ?

 

Maybe check (replug) all your connectors, reseat gpu

 

[Gavpedz]

Will have to get hold of some I guess to test. Weird thing is the ram I have is the recommended for the CPU Ryzen 5 2600

 

Corsair vengeance lpx 3000mhz they were a dual kit. 

 

Would the BIOS update now required different ram or is it that the ram I have is corrupted in some way?

 

Yeah tried both stick in all positions and both work fine by themselves after no power and both work fine in any slot once I have gone through the bios DCOP setting first with one stick. 

 

Attached is what it now says when I try to roll back bios to the version I was on or any before it.

You said you can roll back to other Bioses,

Did you try to and then try your preferred Bios again ?

Please try rolling back to either 4301 or 4202. Hopefully one of them will work.

It is almost certainly the bios causing problems with the RAM and DCOP setting. I had a similar issue on my asus motherboard and 3700x

 

If you need to just have the system run, you can probably have it run without DCOP enabled until a better bios revision comes out.

 

Also worth replacing the CMOS battery.

[Gavpedz]

This is driving me nuts. 

 

I have rolled back to 4202 which is as far back as I can go. I can't go back to 4007 which I originally had as I get the error above. Again same issue system won't post with 2 sticks of ram in. Only posts if I have one stick of ram. Doesn't matter which stick both work and both work in either the A2 or B2 slot. So what's going on? 

 

The only way to get it run two sticks is boot with one stick then in bios turn DCOP ON turn pc off then add the second stick turn back on and all works until the power is off! New CMOS battery has been added despite testing the other battery which was giving 3volts.

LPX kits have the classic XMP issue, basically most of these kits' XMP profiles aren't stable, but I don't think that it's related with this.

Try selecting "Load Default Values" in BIOS and then do a CMOS reset. I know, doesn't make sense but it might work 

[Gavpedz]

Sadly I tried that with no luck. Weirdly now though is when power is off and I them don't get post, do the whole boot with one stick the bios settings are now being saved. So it seems now that it is specifically when booting with two sticks after power out. So it's not that the settings are not saved as they are. 

 

I have tried default settings in bios but it will refuse to boot with two sticks the only way it will book with two sticks is in manual or DCOP MODE.

That's basically LPX RAMs being problematic as usual then. Probably they can't run well and BIOS resets DOCP.

[Gavpedz]

So is the solution to get new ram? If so what ram should I get as that was what was recommended for my CPU Ryzen 5 2600 3.4 GHz

 

Also BIOS doesn't seem to be resting now. After booting from power out (with one stick) I go to bios and all settings are still there. Save, exit boot and shutdown then add second stick and all good. Just booting from no power it throws a wobbly. 

 

Anyone reading this in the future DO NO UPDATE YOUR BIOS UNLESS YOU ABSOLUTELY HAVE TO. Mine was working fine and no issue untill I updated!

That's what manufactorers say, I guess it's at least sometimes true.

I guess it is but with these problems there usually isn't a definite solution, there are guesses. I recommend crucial ballistix (RGB?) 3200/3600 MHz CL16 kits.

Yes that's the weird thing here, it can easily be a CPU-RAM communication issue and that's what I'm guessing.

Thanks appreciate the help. I have just been reading about the LPX versions and seems there are a lot of issues! 

 

Also read that the G Skills flare X 16gb 2x8gb DDR4 3200 CL14 is a good option for compatibility and performance.

Yes they are good too, you can buy the one you like the most. Or better, the one with a better chip.

However I'm almost sure that these both kits have the same, or if not, similar chips.

[Gavpedz]

Ok thanks well it seems the crucial is probably a bit cheaper from what i can see so might go that route. And in terms of installing I am presuming I should just be able to plugin them in and turn the pc on. This whole not posting etc has got me paranoid! 

 

 

I was also just looking at the QVL list and it seems the one you suggested isn't on there is that a problem?? Memory_QVL_AMD_Ryzen_2000_Series_Processors_B450_4DIMM.pdf (asus.com)

I don't think that this RAM will have any issues with your CPU, never used these lists before. 

I should also note that, if you are going for a 1:1 FCLK ratio, a 2600 might not do it in 3600 MHz.

Yes just install the RAMs and turn the PC on.

[Gavpedz]

1:1 FCLK ratio? I'm not looking to overclock or anything just want good 16GB compatible ram that will run well and HOPEFULLY not crash the bios or whatever after power out.  So this should be ok> https://www.newegg.com/ballistix-16gb-288-pin-ddr4-sdram/p/N82E16820164173 or if you are saying 3600 wont do it maybe the G Skills flare X 16gb 2x8gb DDR4 3200 CL14 is better at 3200?

Yeah it shall be ok. Apparently 2600 doesn't have FCLK btw.

[Gavpedz]

Ok thanks. Well at some point I might get some more ram and see if it fixes things. 

 

Thanks for all the help.

[Gavpedz]

Sorry to keep asking bit o have just been looking at some others on the QVL would these be ok? https://www.newegg.com/g-skill-16gb-288-pin-ddr4-sdram/p/N82E16820232476?Item=N82E16820232476&nm_mc=AFC-RAN-COM&cm_mmc=AFC-RAN-COM&utm_medium=affiliates&utm_source=afc-Pangoly&AFFID=3815908&AFFNAME=Pangoly&ACRID=1&ASID=https%3a%2f%2fpangoly.com%2fen%2freview%2fg-skill-f4-3200c16d-16gtzr&ranMID=44583&ranEAID=3815908&ranSiteID=nwUw4CS3F2g-lrjh8K5r0zBINqdcf18oyg

Not sure why did you stuck on that but yeah these are ok too.

[Gavpedz]

Just because it was on the QVL really. 

 

It's all a bit new to me to be honest I build this pc with the help of pcpart picker for compatibility. 

 

Now running memtest86 to see if that shows any errors. 

 

Then going to try figuring out how to set the ram to 2800 as I have read in a few places It doesn't play nice above that although never had a problem before. Also been reading the b-die Samsung plays way nicer with Ryzen than hynix and others. 

 

All getting a little confusing to be fair with what ram is best fit. 

 

Then it will be looking at replacing ram I think so just want to be sure on what would be the best ram to get in terms of comparability with the mobo and CPU and bearing in mind  not to bothered about overclocking

[Gavpedz]

So the memtest returned no errors. But just been checking cpu-z and task manager and i seem to (if i am reading this correctly) have some very odd ram numbers! In the bios it is set to DOCP 3000mhz this is shown in the task manager but the speeds that CPU-Z are totally different. Both the ram sticks should be 3000 and are marked as 3000mhz on the casing of them.

That's normal - DDR = double data rate, you need to multiply by 2.
