F9 and 0d Q-code seen with new RAM

Hi,

I'm currently running a ch7 Hero x470 (wi fi) with 16GB Corsair Vengeance RAM CMU16GX4M2C3200C16 :
https://www.corsair.com/uk/en/Memory-Size/vengeance-led-configurator/p/CMU16GX4M2C3200C16

I have both sticks running in slots A2/B2 as specified by the manual and they run without issue when using ASUS's version of XMP.

All the above is well and good until I decided to purchase some G-Skill F4-3200C14D-16GTZR for the tighter timings.

If i use RAM slot A2 with the new G skill memory ( either stick) then the system will lock up with the yellow LED lit up and the Q-code displaying 0d/F9. Does this mean the RAM is suspect?

The system will boot if I place the sticks in the other ( A1/B1) slots but even when leaving the timings on auto I could only get the G skill to boot at 2800MHz and no faster.

I tried upping various settings like the ram voltage (1.4v) SOC to 1.1v and ProcODT up to 60ohms but that was no help.

So in the end i popped the corsair stuff back in and away it runs with no issue at all so it's gotta be the G Skill at fault-Right?

Many thanks for any insight given.. 🙂

I should also mention i'm using Bios 1001, having tried both 0804 and 1101.

This is great, thank you.

Now to get some serious reading done.

Many thanks once again Gupsterg!

NP 🙂 .

What I would do is save your current setup as a profile within Tools > ASUS User Profiles . This way you can go back to something stable when you need it.

Then save it within a second position as well, name this your "base OC profile" or whatever you think is right. Makes changes below/save and work on profile.

Within this base profile I would leave:-

Trcpage [Auto]
Trfc2 [Auto]
Trfc4 [Auto]
Trdwr [Auto]
Tcke [Auto]

Next I'd set manually:-

TrdrdScl [2]
TwrwrScl [2]
TwrwrSc [1]
TwrwrSd [7]
TwrwrDd [7]
TrdrdSc [1]
TrdrdSd [5]
TrdrdDd [5]

The timings with [7] [5] I would only lower once you have reigned in other timings, all the way up to 3466MHz you should be sound with setup IMO. The timings with [2] you can slacken to gain some stability, but be aware they give best performance gains.

Set Tcwl equal to CAS, if using odd CAS set Tcwl to CAS - 1, as odd Tcwl hasn't worked at frequencies I have used. For odd CAS to not be rounded up to nearest even Gear Down Mode must be [Disabled]. I'd also set Power Down Enable as [Disabled].

I always gun for Cmd2T [1T], but you may find 2T helps you stability wise. If you do use gear down mode then leave Cmd2T setting on [Auto].

Trtp you should be able to snag 8 to 10, I even have it as 5 on one rig. You should be able to just keep changing this independently of other settings IIRC.

You should be able to use

TrrdS [6]
TrrdL [9]
TwtrS [4]
TwtrL [12]

If need be just slacken these by a notch each. Once later profile is sound you may gain a notch or two lower on these.

Start Tfaw at [36], later lower if you can (ref the rule in link). Start Twr at [12], you may gain it as 10, I have one rig set this way, slacken a notch or two from 12 to improve stability. Start Trfc at [400], with only giving VDIMM 1.35V to 2 differing sets of G.Skill, I can have this as 274 for 3400MHz/3466MHz.

You may be able to use all the way upto 3466MHz :-

DRAM CAS# Latency [15]
DRAM RAS# to CAS# Read Delay [15]
DRAM RAS# to CAS# Write Delay [15]
DRAM RAS# PRE Time [15]

Start at a lower frequency like 3200MHz, be systematic in changes, keep notes.

It can seem daunting to initially setup your own timings, but once you tinker a little a few times it becomes easier IMO.

Wow many thanks...

I'm currently reading up as much as i can and the above will be invaluable.

No problem 🙂 .

Doing your own timings is rewarding IMO 🙂 . I also think you can get addicted to tinkering 😉 . I feel at times I liken it to gaming in my mind. So in a way I'm playing a game with my tinkering 😄 .

Look forward to reading how it goes for you 🙂 .

So totally agree my friend.
To help us help you - please provide as much information about your system and the problem as possible.

:cool: .

The memory presets by The Stilt within the UEFI have worked really well for me, without any real tweaks other than SOC/VDIMM. Again though read some have issues. Some got them going with other minor tweaks.

Morning Gupsterg,

I did try one or two of the presets but not much luck so far.

I'm currently trying to get used to the ASUS bios and it's idiosyncrasies, something I'm really familiar with using a Gigabyte set up.

My current goal is to get the RAM running at 3200MHz manually. Once i'm familiar with this process i can then go on and make further tweaks.

I've copied your suggestions into a little notebook i use when overclocking so I can keep tabs on any settings changed.

Many thanks once again..

Hi Gupsterg.

The solution to my issue turned out to be a new board.

You may or may not have noticed the thread about the A2 slot being dodgy well his symptoms exactly matched mine.

Fitted it today and the G- skill run as it should straight away.

Many thanks for your time and effort.. 🙂
