Flare X 3200MHZ 16GB 2x8: F4-3200C14D-16GFX // Performance & Guide

Level 7


Ryzen Memory and the hate from non-certified B-Die variants is easy to find. Information pertaining to Flare X memory is lost to the vast amount of issues that consumers are having with older modules and or Hynix chips. There is actually a good write up of these chips on an i7 chip, WTF! This is meant as a repository for Flare X 3200Mhz memory only, and without raising the CPU FSB (BCLK) I will update this with information on the 8x4 kits once they are available. GSkill will have the 3466 kits available soon, but with the current performance of the 3200Mhz... It might be a waste of time and money (If you just want to achieve the 3600Mhz mark) ... but GSkill can send me a kit if they want!

This thread will only focus on the intended 100Mhz FSB. This is the most important factor: 3200-3600Mhz are all using the rated timings of: 14-14-14-34-48 and 1T. Also keep in mind that this system is running on an Ekwb extreme loop, Supremacy Evo block and several reservoirs: so your results may vary if heat is an issue for you. I also do not inflate numbers for any reason. The Aida numbers listed here are under a normal workload, normal environment, and with normal programs running in the background; even the complete Adobe CS 2017 suite of BS that runs in the background. Obviously the numbers could be improved, but you wouldn't want to do an excessive BCLK overclock while sacrificing stability and being forced to increase latency. (Agesa 1.0.0.6) Bios Release candidates (Non-Beta) should slightly improve these numbers in the next few weeks.

Testing is done with:

Ryzen 1800X @ 40.75 Multiplier (4075Mhz The best overclock with overall stability in mind)
CPU FSB @ 100Mhz
Flare X 16GB 2x8 3200Mhz:
Amazon: https://www.amazon.com/G-SKILL-Flare-288-Pin-Memory-F4-3200C14D-16GFX/dp/B06XWKNMQQ
Newegg: https://www.newegg.com/Product/Product.aspx?Item=N82E16820232530

Before we get into 3200Mhz and beyond; the numbers for 2400Mhz:



Basic rundown:
2400Mhz: 36263 MB/s @ 90.8 ns (Latency)
3200Mhz: 48705 MB/s @ 73.3 ns (Latency)
3466Mhz: 51551 MB/s @ 69.2 ns (Latency)
3600Mhz: 38422 MB/s @ 67.3 ns (Latency) // Obviously issues to be resolved & excessive heat. Only improvement is in Write speeds.

-3733Mhz fails to boot with the rated timings and settings described below.

@3600Mhz // You may also get a BSOD: System_Service_Exception due to: for WIN/AMD driver problems and/or excessive heat. I can only suggest to run 3466 for the stability, and be happy you are at the 3200 and beyond spectrum.

Choose your speed and using the following voltages: 1.35V (3200Mhz) 1.38V (3466Mhz) 1.40V (3600Mhz) The following screenshots are for use with a 3466Mhz setting. Also note: Bios voltages show 1.395 as the shots were grabbed when going from 3600Mhz to a 3466 w/o a reboot // you get the point, etc:

Step 1: Extreme Tweaker (Mild Overclock and Ram Voltage)




Step 2: DRAM Timing (force the rated timings and select 1T-CR)




Step 3: Digi+ Power Control (vBoot located at the bottom)




Step 4: ProcODT & Fail_CNT (This is the most important aspect aside from forcing 1T-CR and the low rated timings)




Step 5: Ensure that the 2nd set of Power Down options are disabled // (optional)



Notes: Cold boot will do a single reset but that is why we force a (4) Fail_CNT which is plenty for a good power on.

Now the current Bios: 1401 for this memory has made more improvements:

3200Mhz @ 1.35 Voltage & 1.35 vBoot:



3466Mhz @ 1.38 Voltage & 1.38 vBoot:



3600Mhz @ 1.40 Voltage & 1.40 vBoot:



It seems that the 3466Mhz settings may offer the best overall performance.

Memtest x64 was run for 90 minutes on all 3 tests with 0 errors. One thing to note: Bios 9943 & 9945 introduced a new bug (at least for me) Win10 will now only show 1200mhz (rated 2400Mhz) in task manager for anything above 3200Mhz settings. CPU-Z will be blank with only timing display for anything above 3205Mhz (1599.7 and lower will display) and Memtest will also only show 1200mhz. Aida 64, RTC and Bios displays proper frequency every time. Hopefully this will be fully resolved soon. You will NOT want to use Bios: 9945 with this memory kit.

Update: Windows 10 updates have fixed Memory speed in Task manager June 13, 2017

Update: CPUZ fixed in latest version, ROG skin update as well.

MemTest64 (tested at a minimum 0f 90 minutes on all speeds) regardless of speed shows 0 errors:




And for a Overclock increase with the 3466 strap going from a 40.75 to a 41 Multiplier:



As a comparison with a +3 (103 // CPU FSB) 4120MHZ CPU & 3300MHZ Memory:

Summary: Initial performance was lacking, but with a beta 1.0.0.6 code it is performing beyond my initial expectations. Now if we can overclock the Ryzen like these modules...

@aeonconcepts How did you manage to take screenshots of your bios please?

usb stick + f12 in UEFI

too many people are using different cpu's. One person is using an 1800x, someone else a 1700 and another 1700x. We should have threads for each, without the others on it. It would be a lot easier for like builders to share info.


It's thread for memory O.C. , and this particular set of ram is first and only advertised for AM4. So I think it's ok to have 1 thread for it.
After all 1st. gen Ryzen are practically the same CPU with different binning (if my info is correct)
it's done with FBS @ 100 Mhz, so basically your luck with the memory controller.
It's def a good idea to have ppl list their spec so other ppl can help, share or search quickly.

Thanks for that andyliu I can now save screenshots of my bios I'll try it on my board crosshair vi hero sometime.

Hello everyone, I know I'm necroposting but I felt like this would be the most appropriate thread for my issue.
Like many of you, I use a C6H paired with 2x8Gb of G.Skill FlareX 3200Mhz C14. From what I've gathered, they're single sided, Samsung b-die's.

I'm somewhat experienced with overclocking and generally tinkering in BIOSes, but Zen is really something else so I'm a bit lost. I've followed the guide step by step and I'm starting to get the hang of it. My RAM has been running @3200Mhz 14-14-14-34-48, 1T @ 1.35v, BCLK is left @100Mhz and my R5 1600x runs at 4Ghz, 1.375v. I don't want to overclock the RAM past 3200mhz, I'm fine with that. I do some rendering so it's safe to assume that it's stable 😄

However, just recently I did some tests with SMT on/off. I settled with SMT on but the "Sleep" Feature wasn't available again. Of course, because of the cold boot issues I usually leave my PC in sleep state when leaving. I couldn't wrap my head around that bug so I thought of just resetting the BIOS.
Will I was at it, and since I didn't update my BIOS for a while (was running something like 1709), I updated it using EZUpdate so I guess I'm now running the latest stable version. I believe the version number is 3553, will check ASAP (not at home atm).

With both BIOS, the system runs fine but... I'm pretty sure I had less failed cold boots with the previous one. It might just be a placebo kinda thing though, but what messes with my head is a particular setting that's missing/been renamed/moved in the latest BIOS: http://ueemmi.com/wp-upload/images/2017/06/04/07.png

With the previous BIOS, I had this Fail_CNT setting and it helped me a LOT when I bought and build this system (around October 2017). Is the Fail_CNT setting has been replaced with the one that allows you to specify a number under which it won't revert to default settings? (sorry again, not at home, will edit) At the moment, my system will fail twice, sometimes thrice, then POST. Before, it was one or two.

Any ideas or suggestions guys? Thanks in advance 🙂

As a side note, how does repeated failed boots affects HDDs? One of my two (Identical) HDD is a bit more noisy lately. I can hear the heads retract, which wasn't the case before.

I gotta admit that those cold boot issues are really a shame with such "high-grade" hardware. It was a very costly decision for me and although I don't regret it, I'm a bit disappointed. So I don't want to sound rude but... Why is this isn't fixed already? (It's a legit question, I'm curious as of why this is still a thing)

Which Crosshair VII Hero (wifi) bios has ProcODT & Fail_CNT settings in the bios?
(This is the most important aspect aside from forcing 1T-CR and the low rated timings)

Sry, been working on Threadripper and CH7 builds. I'll get this updated soon for the CH7, no longer have a fully functional test bed for the CH6. The CH7 & 0601 Bios does provide a small improvement with Flare-X with some very specific timings. I'll go into more detail on that with an update to the original post. Here is a stable 3466Mhz on a 2700X running at 4.25Ghz:

74116

It is now possible to reach sub 60 latency values at 3200+ speeds.

Nice, I'm looking forward to the guide.

I've managed to get okay results by simply plugging in values from the ryzen ram calculator but would definitely like to try and lower that latency even more.

Could you please provide all the settings in BIOS that you've made ? I'm trying to push my 2700x with FlareX further. Right now I'm sitting with my 2700x @ 4.15 GHz (103.4 x 40) with 1.35v and my FlareX @ 3444 - 14-14-14-28-CR1 @ 1.4v. I even could boot with my RAM @ 3525 *same timings like 3444*, but different FSB X multi.... More tests coming.

Thanks.
