Setting up G.Skill F4-3200C14D-16GTZRX

Hello,

I've just purchased F4-3200C14D-16GTZRX.

I've got information that these modules provide AMD Ryzen optimized Samsung B-die chips - Is that correct?

I want to run the memory at least at its specified parameters: 3200MHz, 14-14-14-34-1T, 1,35V.

I've got an ASUS Crosshair VI Extreme board with a Ryzen 1800X processor.

I've tried to use AI overclock tuner in the BIOS and select D.O.C.P. Standard and I've also tried to manualy input memory settings (14-14-14-34-1T, 3200MHz, 1,35V).

My computer either boots up with JEDEC #6 values at 1066MHz memory clock or freezes and reboots within few minutes after booting up Windows 10 Pro.

This also happens at lower frequencies (3066, 2933).

Is my RAM defective?

I was using Corsair CMU16GX4M2C3200C16R successfully at 3066MHz but returned it to try G.Skill memory that claims to work at 3200MHz with Ryzen. But for me it is not even working at 2933MHz ...

---------------------------------------------------------------------------------------------------------------------------

I have returned the memory kit as it was IMHO faulty. Received a new one today and although not perfect it behaves much more reasonably.

I was able to set AI Overclock Tuner to D.O.C.P. Standard (3200MHz, 1,35V, 14-14-14-34).

AIDA64 Business Cache and Memory Benchmark passed without any problems.

But when I ran System Stability Test I've got a "Hardware failure detected! Test Stopped." message after few minutes and few minutes later the system froze and rebooted.


So I've tried to set the timings manualy leaving D.O.C.P. at default.

14-14-14-34-2T, 1,35V, 3200MHz: Unfortunately the board does not boot with 3200MHz for some reason - after boot JEDEC #6 values are effective as shown with CPU-Z

14-14-14-34-2T, 1,35V, 3066MHz: Cache and Memory Benchmark passed without any problems. I've run System Stability Test for almost 10 minutes but then I've got a "Hardware failure detected!. Test Stopped." message .Few minutes later the system froze and rebooted.

14-14-14-34-2T, 1,35V, 2933MHz: Cache and Memory Benchmark passed without any problems. I've run System Stability Test for 19 minutes without any issues.

I've performed more tests a bit later:

14-14-14-34-2T, 1,35V, 2933MHz: Tried to reproduce the 19 minute System Stability Test run several times but unfortunately the system either freezes and reboots or I get a "Hardware failure detected! Test stopped." message few minutes after the start.

14-14-14-34-2T, 1,35V, 2800MHz: Cache and Memory Benchmark passed without any problems. I've run System Stability Test for 2 hours and 3 minutes without any issues but then I got a "Hardware failure detected! Test stopped." message.

Can you please give me advice on how to configure the system for better stability and performance?

I bought the most expensive and powerful AM4 components (motherboard, CPU, memory kit) so I hope there is a way to run them at 3200MHz which they all AFAIK specify to support.

Thanks.

power down, press clear CMOS + power up, shut down, unplug PSU, clear CMOS, boot - at least this helped me when I soft bricked mobo after wrong p-state OC
sometimes reflash helps too

Tried to reset CMOS and input all settings again.

Doesnt even boot up at 2666MHz so I am running at 2400MHz. :mad:

Is the CPU bricked, the motherboard bricked or the RAM bricked?!

Did a BIOS flashback and reentered values.

Now I am back at 3066MHz and all seems to work fine again. 😄

But if the CLDO_VDDP testing caused this issue with memory unbootability even at lower frequencies then we do not know whether it happened sooner than the potentialy right value for 3200MHz if any was entered.

Is not there a more sophisticated approach to finding the right CLDO_VDDP to make 3200MHz bootable? Brute forcing it with 61 power on/off cycles is tremendously tedious and due to this bug also problematic.

Found a way to further improve performance, adjusted the following values according to Stilt's Safe 3200MHz preset in BIOS:

tRAS: 34 -> 28
tRC: 48 -> 50
tFAW: 39 -> 36
tWR: 24 -> 10
tRDRD SCL: 3 -> 2
tWRWR SCL: 3 -> 2
tRFC: 560 -> 307
tRTP: 12 -> 8
tRDWR: 7 -> Auto
GearDown: Enabled -> Disabled

Looks Great! :cool:

The previous benchmark for the 1usmus 3200MHz safe values for comparision:

good you restored previous state with flashback

you can change RAM power down option (should be disabled) - this will lower memory latency - around to 71-74ns in your case (for 3200 I had 70-72ns)
this one is safe and don't negatively impact stability (actually can help a tiny bit)

"bank group swap" disable and "bank group swap alt" enable could give some boost too - just a warning it may affect stability in some rare cases - but you are one of those rare cases where nothing wants to work 😛

Wouldnt that interfere with sleep mode? I do not like to shut down my PC completely ... Powering down RAM sounds like a good way to increase its longevity.

I am under the same impression for quite a while now. 😛

Which one gives the boost - disabling BGS or enabling BGS? And what is BGS good for anyway?

>Wouldnt that interfere with sleep mode? I do not like to shut down my PC completely ... Powering down RAM sounds like a good way to increase its longevity.
it has nothing in common with PC sleep mode
it is to control ram power mode - enabled saves little power but increases latency

>Which one gives the boost - disabling BGS or enabling BGS? And what is BGS good for anyway?

for single rank, 1 DPC settings are as I wrote above
BGS enabled make access faster
don't turn BGS and BGS alt in same time - either one or second

you ask too many questions - you should read some ryzen overclocking guides :rolleyes:

Please correct me if I am wrong. But there is no "BGS alt" setting in BIOS. The DRAM calculator just states that you can alternatively set BGS to Enabled.

Therefore I cant set BGS to both disabled and enabled, right?

Could you please point me to a good guide? Now that I have my memory set up I would like to boost CPU to a stable and safe setting to not affect CPU longevity much.

If I raise BLCK to 104,8 do I need to adjust RAM timings?

So I've got a HUGE problem now.

I've left AIDA64 System Stability test run overnight for 13hours 30minutes. The new settings worked flawlessly.

But when I rebooted my PC the board beeped 3 times again refusing my RAM: "Your memory settings have been reset due to failure to boot".

So I've done a BIOS flashback, reentered all settings, but this time it did not help.

I had to boot at 2666MHz since all higher frequencies were refused also.

Any idea what could be causing this misbehaviour or how to fix it? It is a source of tremendous frustration to me. :mad:
