Most likely the memory, and I don;t think its OC'd. Most here have PC 3000 ram or 3200 that I have seen, but many motherboards only get to that speed with the "correct" ram, usually samsung-b chip ram, single sided (I think thats the correct term)

Single rank.

Double sided can be single rank iirc.

My G.Skill FlareX 3200 is on the QVL for the Gigabyte Gaming 3 (F5 BIOS), but given that the RAM was released after the board/latest BIOS and the fact that it isn't stable on it at any speed above 2400... I'm going with BIOS being the issue. Because it works 100% on 1-click A-XMP on my MSI motherboard.

I'll have to see how it does on the ASRock X370 Taichi and the Gigabyte AX370 Gaming K7.

I have that same ram being shipped to me Monday from Newegg. Hope it works on the C6H with 1002 BIOS.
 
As @Agent-47 said you can find out if the chips are Samsung or Hynix by the serial number. G.Skill3200 CL16 should not be Samsung. The CL14 version are Samsung b-die based.
I am not sure about the 3400 CL16...

yes. I found a guy on Ebay selling a F4-3200C16D-16GTZB and it was a hynix. Had it confirmed by messaging him for his serial no and for his Thaiphoon report.

also found a F4-3400C16D-16GTZ and it was a Samsung Rev D.again on Ebay

also a F4-3000C15D-16GVR that was Hynix. again on Ebay

I think some if not all C16 are hynix while all C14 are samsung rev B if its a 8 GB module and rev D if its a 16 GB module.

it makes sense as Rev B is used in high speed modules with tight timing.

OK, I am confused. It appears that your $210 memory (4000, CL21) is running at the same speed as my 3200 CL14, but costs $40 more ! What am I missing ? Why would I spend $40 more for the same speed ?

most likely because when the BIOS is unlocked to support higher clocked straps, you will have a better chance of hitting 4000Mhz with the more expensive modules. 😛

@unseenmorbidity have he tried lowering the multiplier and do a BCLK OC? you can hit 3840Mhz at 120 Mhz BCLK.

None. I got it on sale for $195 before the 3200 flarex was out, and I am just happy it worked by loading the xmp and copying the timings.

3.9GHz 1.35v & 3200 cas 14

Twas a good day.

OK, still confused. Its still $25 more than the 3200 cl14 I have. After all the work it has taken to get to 3200, I am not holding my breath on 4000 anytime soon.

But his is "better looking".

I think he is just offering it as another data point.
 
BTW, microcenter in fairfax had an openbox taichi 370x for $159.

Almost bought it, but hassle of returning my newegg order and the uncertainty of an openbox part made me skip it.

Dang... I would have gotten it, and resold it for a profit !

The flarex is $184 though.

4000 might indeed be pointless, but I am hopeful of at least 3600 since amd mentioned updates for supporting higher speeds. I might dabble with some bclk oc'ing too.

I think I enjoy tinkering over playing games anymore.
