Crosshair VI Hero: UEFI build update thread

[skellattarr]

I flashed 9920...still crashes. Luckily there are cash dumps. This is the error:


WHEA_UNCORRECTABLE_ERROR!

I searched a bit online and most people say that disabling CPU overclocking solves that. Thing is, I want the extra performance (from 3.00 to 4.00 Ghz there is quite a gap). CPU voltage is 1.375 and it is stable with temps between 55-65 C.

The observations I have made so far:
1) It started happening after BIOS 1201 (so it is clearly bios related - doesn't have to do with CPU cooler pressure)
2)Happens mostly during gaming and very rarely while surfing, idling etc....
3)Happens a lot more frequently when the XMP 3200 profile is active but it can happen with just about every memory setting combination as well.
4)Happens about 4/10 times I try to load FIFA 17 (as soon as the exe is loaded into the memory). If it happens once and I try to open FIFA again after the restart without going in the bios it has a much higher chance to happen again (crashed on that spot 4 times in a a row once - so 4 restarts just to open a game ) GTA V also makes it happen usually during gameplay.

Any comments?

I could be wrong but that whea uncorrectable error could be a faulty cpu look in event viewer and see if there are any whea loger errors or warnings in there if there is then the cpu has a problem. i had one do that to me and amd replaced it

can you not use the pstate method instead. exact same end result...

You just need LLC level 4 to stop the majority of the drops. This will result in the thing running at .2V higher than what you have it set at during full load, it will still dip, but when it dips it will dip to what you have it set at in the bios, instead of undervolting like it does now. You might actually be able to drop your voltage .1 to compensate for this, but I probably wouldn't recommend it. I don't think you need to mess with current, I think this is more of an extreme overclocking tool.

I have read that Ryzen CPU's and CPU's in general have a break in period where you might be able to achieve higher overclocks for a few weeks, but once the chip settles in a bit you will need more voltage. I've had this board since day 1 pretty much and have been through just about all the bios revisions. When I first got the thing it ran stable at 4GHz at 1.37v LLC 3, bios 1201 it ran at 4ghz at 1.38v LLC4, now i need 1.46v LLC5 to hit 4ghz. So there may be some truth to it. I actually bounced back to Bios 1001 to test this theory, I had 4.25ghz on there at one point when it was first released, but it didn't help. I could still only get 3.925 GHz without cranking voltage.

Honestly your probably just better off dropping your overclock in .25 ghz increments until it's stable if you are already pushing 1.4V The difference between fully stable 3.925ghz (stable) and 3.950ghz (half ass stable) for me is like .5v. You have to find your sweet spot with Ryzen, which is typically anywhere between 3.8 to 4Ghz with a non X chip.

Also when you test with cinebench, don't just run it once, run it like 5 times in a row. Then run it a few times every time you start up your computer for like a week. You can think you have your overclock good and a few days later it will crash. Eventually you will find your sweetspot, at least until the next bios =)

EDIT: I tried dropping the VDDP, this did nothing for me, but Ryzen is a tricky beast and you have to master your specific CPU, which can be tough.

I ended up using 1.4V with LLC level 2. This keeps voltages between 1.373 and 1.395 which is just great and it is now perfectly stable after 1 hour of prime 95, realbench and multiple cinebench runs. But it still seems weird to me that bios updates destabilize OCs that much. Thankfully temps are still fine (only slightly increased - I am still well within the 60-70 mark with quite high ambients (30-32 C) cause it's summer). Thank you all for your help and lets hope future bios updates don't mess up things further in that regard!

I have problems with boot time.

With my previous system its like 8-10 seconds to boot up.

Now best i can achieve is 25 seconds.

Bios 1403.

How can i fix this ?

There is no program running at startup. All drivers updated.

And sometime corsair h115i white led turns into red. Not using Corsair link and AURA because it crashes all the time. I looked at the temps during gameplay its around 20-25 on idle and 50 ish on load. SO i guess its not about temps.

Thanks.

I think you can probably get the same results @ 1.38v, maybe even 1.37v with LLC 4, basically with LLC2 1.4v you are just overvolting the chip when it isn't needed, then it drops down to the 4ghz stable voltage range at max load. Basically you are throwing an extra .03 to .05v at your processor all the time under light loads (normal everyday usage), when it's almost guaranteed not to be needed. So it's a bit bass ackwards, but if it works for yah, more power to you =P

Here is what I settled on for settings in the CBS section:







Here are my modified ram timings from the first 3466 profile from bios 1501. They provide a much smoother playing experience at least for me. The ram kit used will not boot at C14 and 3466.






Have since raised Trc to 47 and no more cold boot problem anymore; completely vanished.

Spoiler tags would have made this post a lot less annoying.

Thats the same way I optimized my rig bro !

Had at first 1.3v LLC1 @ 3.9ghz but in Prime it went to 1.26v.
that bugged me... Now I'm driving 1.2v with LLC4 while "Priming" it goes up to 1.26 and stays stable and on idle i have 0,1v less..

Love it !

Did anything changed over beta 1501

or

the official 1501 is as same as beta 1501 ?

Thanks.

Btw, with the new official 1501 ; AURA is working now.

3900 mhz at 1.375v and docp standart works like a charm.

cpu temps goes a little bit higher. like 3-4 C.

Main problem is does anyone know how to fix it ?



I am Turkish. My system language is in Turkish. But RyZen power plan is in russian ?

official 1501? where?

What do you mean by a little higher? comparing to what?
You can try to lower the voltage and have lower temp, but it depends on your CPU. Not all CPU created equal.
And I dont see anywhere to have official 1501; if you dont see a version bump, you can pretty much assume they are the same unless noted.
