Ryzen 1600 + RAM OC = bootloop | But individual OCs = fine.

Specs:
Ryzen 5 1600 with stock Wraith Cooler (and of course, aftermarket thermal paste).
Asus Strix B350-F Gaming
1x8Gb - Corsair Vengeance LPX 2400mhz CL16 @ 1.2v
RX 580 8Gb Sapphire Nitro+
Corsair CX600 PSU
(Samsung 850 Evo - 2nd HDD Seagate - 3rd HDD Western Digital)

I am having trouble holding both a CPU & RAM overclock.

CPU overclock:
3.8Ghz wit 1.300v {with the offset, + ~0.0625v}
CPU LLC - High
Power Phase (Optimised/Extreme - no noticeable difference either way).
TEST - Ran a dozen Cinebench R15 Renders & I peak at about 70 degrees max.
(I won't be running Prime95 or increase the voltage much more on the Wraith cooler - aftermarket solution on it's way) ;)
TEST - Long 4-6-8 hour gaming sessions, temps are in control (never about 60-65 max).

RAM overclock:
2400Mhz CL16 overclocked to 2933Mhz (first with Auto timings @ CL20).
This wasn't really stable, (corruption in game, but no memory errors or blue-screens) so I increase the following:
DRAM Voltage: 1.2v->1.35v
SOC Voltage: 0.900v -> 1.125v {with the offset function, + 0.0250v}
Timings lowered back to CL16.
To summarise RAM overclock: 2933Mhz CL16 | DRAM 1.35v | SOC Voltage: 1.125v
TEST - I ran 2 passes of MEMTEST86+ for almost 2.5hrs with no errors.
So I set both the CPU & RAM overclock on, the PC did a coldboot, then went in a boot loop once or twice (I powered it off, it booted normally without resetting BIOS settings).
TEST - Cinebench a couple of times
TEST - Unigine Superposition
TEST - Total War: Warhammer 2 Benchmark run a few times.
TEST - I then did an 6-8 hour gaming session (or marathon, whichever you prefer) :D
Absolutely no issues whatsoever.


The issue lies when I reset the PC to turn off my overclock, but also to see why I got those bootloops a few times.

I have come to the conclusion that:
CPU OC on it's own is stable
RAM OC on it's own is stable
CPU + RAM OC together is failing to boot. (I can only assume this is due to a power delivery shortage somewhere, upon boot).

I have tweaked the LLC for SOC Voltage from Auto to Regular (next options are High & Extreme) as opposed to CPU LLC which goes from (Regular -> Medium -> High -> Extreme).
I even loosened the timings back to CL20
Tried Power Phase Control: Optimised / Extreme :but neither make any difference.


I haven't tweaked the OHMs yet (I hear between 40 & 60 OHMs with 80 OHMs being the highest, can help?)

The thing that really bugs me is 2933MHz CL16 on it's own, without CPU OC is perfectly stable.

Is this what LLC is for - should I try a higher SOC Voltage LLC?
Has anyone else had similar issues when overclocking both CPU & RAM?

Appreciate your help with this as I more settings to play around with still - (all thanks to AlienALX's suggestion of going with the Asus Strix B350 board instead of an MSI one). ;)

Generally I am very happy with my set-up, but I cannot resist the urge to tinker-tweak-overclock & bench.

Absolutely love it! :D
 
Try more SOC volts but at the end of the day you are trying to OC the memory - its not actually rated for 2933
 
Thanks RobM, appreciate the link.
I had watched that one before (and every other video, I could find before posting for help).
He does say to tweak the OHMs so I get your message loud and clear.

OHM tweak, here I come!

@Tom
A reply from the man himself. It must be Xmas. :)
Trying to get 2933 from a 2400 rated stick, hmm..maybe I am trying to be too optimistic with that OC.

I am hitting 1.125V SOC Voltage already..I will try a bit higher but I hear the limit is 1.2v or so I heard.

TBH I was hoping to leave some headroom for (3200) if at all possible. (some might call me crazy but it won't stop me from trying..)

Keep you posted.

Thanks!
 
Check this guy out he overclocks the 1600 with stock cooler on the strix board in this clip


IT WORKS - I CAN'T BELIEVE IT WAS THAT SIMPLE!

So I changed the OHMs (as this was the only thing I hadn't really tweaked yet) and I changed it from AUTO -> 60 OHMs with 2933 & Auto Timings (CL20).
It booted up straight away, no boot-loops!

I then tried to lower this but could only get as low as 53.3 OHMs (any lower @ 40 or 48 OHMs and I would get stuck in a boot-loop).

For anyone else in a similar situation:

My working OC settings (until I decide to push things further) are:

---

CPU
Ryzen 1600 - 3.8Ghz @ 1.3v *actual voltage as per BIOS & HWINFO* {Offset +0.0625v}

---

RAM
RAM 2400Mhz CL16 @ 1.2v [Overclocked to 2933Mhz CL16 @ 1.35v]

Additional tweaks to get the RAM Stable/booting with CPU OC:
ProcODT @ 53.3 OHMs with SOC Voltage @ 1.125v *actual voltage as per BIOS* {offset +0.0125v}

You guys are the best.

A big thank you to Rob & Tom. :cool:

Glad you got there in the end mate, wish my wife would let me have my ryzen gear, still sat there unwrapped and I so wanna play :D :D
 
Glad you got it figured out. RAM can be a real pain to overclock and it's why I usually always just but sticks meant to run at the speeds I'm wanting. Plus, overclocking RAM was never as much fun as overclocking CPU's at least to me. Maybe there are too many things to tweak in OC'ing RAM and my lack of attention span can't handle it lol.

I couldn't agree more on the point of "just buy RAM at the rated speed you want it to run".

But with current prices being what they are, £200 for 16Gb @ higher speeds just feels like extortion to me.

That is the reason why I am running only 1 stick of 8Gb at the moment, and @ 2400Mhz rated speed.

(2nd stick to arrive just in time for the Xmas holidays - a whole week of tweaking timings, voltages & OHMs...lovely). :)

Previously (and on these forums too, funny enough) I had managed to OC some DDR3 Crucail from 1600 to 2133Mhz which I was pretty happy with, now it would appear that DDR4 RAM, from my very little experience with it, is more flexible with a higher clock gap from Rated -> Maximum OC - being better that DDR3.


As soon as I have that 2nd stick I will push both to even further & post back, for I have only just begun. ;)
