TridentZ 3200 Cas16 - Sabertooth Mark 1 Z170, can I downclock ram to fit QVL? HELP!

[Mim3tic]

Ok i'm not sure if I made a mistake here but I ordered the:
"G.SKILL TridentZ 16GB (2 x 8GB) DDR4 3200 16-16-16-36 (PC4 24000) Intel Z170 Platform Desktop Memory Model F4-3200C16D-16GTZ for my Sabertooth Z170 Mark 1.

Asus QVL list states this for verified Ram compatibility(ram they Tested). Since high speed DDR4 can be finicky with boards I want to make sure that I can downclock the ram to match the 3000 Tridents which made there list. Take a look here for example, here is what ASUS lists on there page for working/tested Gskill DDR4 memory speeds:

Qualified 3200Mhz

G.SKILL F4-3200C16Q-16GRR 16GB(4GB*4) 16-16-16-36 1.35V
G.SKILL F4-3200C16Q-16GRB 16GB(4GB*4) 16-16-16-36 1.35V
G.SKILL F4-3200C16Q-16GRK 16GB(4GB*4) 16-16-16-36 1.35V


Fine my Tridents aren't there @ 3200 but they are @ 3000Mhz since it lists the F4-3000C15D-GTZ while I have the F4-3200C16D-GTZ and this is where it gets interesting since it seems that the 3000 are just lower clocked, maybe I can down clock on my ram to 3000 so that I can change the cas timings to 15 instead of 16 which would make my ram the same as the F4-3000C15D-GTZ

Qualified Gskill 3200Mhz:

G.SKILL F4-3000C15D-16GRR 16GB(8GB*2) 15-15-15-35 1.35V
G.SKILL F4-3000C15D-16GRB 16GB(8GB*2) 15-15-15-35 1.35V
G.SKILL F4-3000C15D-16GRK 16GB(8GB*2) 15-15-15-35 1.35V
G.SKILL F4-3000C15D-8GTZ8GB(4GB*2) 15-15-15-35 1.35V

G.SKILL F4-3200C16D-16GTZ-16GB(8GB*2) 16-16-16-35 1.35V <--My Ram

Does anyone know if this is feasible and can work, or if the I can run the XMP profile on my 3200Mhz and have them work without resorting to trying to down clock the ram for compatibility.

You can definitely set the RAM to a lower value and work just fine. At this time, it doesn't seem like the motherboard can support DDR4-3200 8GB modules. Maybe in the next update, or you can try manually boosting voltages to force the system to be stable. Let us know how it goes!

It goes like this. I bought and have in my hands the ASUS ROG MAXIMUS VIII HERO Board and cancelled my order from Amazon for the Sabertooth Mark 1 since they delayed my order for 8 days after telling me thst it would./ being out of stock of them.

Now technically I don't have the Tridents in my hands as they are still on route from NewEGG although I should have them within a day or 2 from now. Asus Claims the Maximus can run DDR4@ 3800.

I assume 3200 should not be an issue?

[GSKILL TECH]

No issue at all

Wow these Trident's are very elegant looking in person. Pictures from the retailer website don't do these enough justice and they weight quite a bit(thick Aluminium). This is not your typical paper thin sheet of Aluminum wrap around heat spreader like on my old red DDR3 1600 ripjaws. They are beautiful in the aesthetics department and there color theme dark grey/black brushed aluminium with a hint a red fit's perfectly with the dark grey/black and red of the Rog Maximums Hero color motherboard.

Hopefully today I will get a chance to open test my board with these little babies.

Quick question, selecting XMP on the bios increases my CPU voltage automatically high. I get that this is need for the ram to run at such high frequency and so the CPU is automatically overclocked to 4.2 Ghz when reading the XMP profile off the ram. For OC purposes should I instead manually input the ram values and voltages in, rather than use the XMP?

[emissary42]

Well the XMP is not intended to overclock your CPU, but some MB manufacturers decided to couple these things regardless. So if you don't want to overclock your CPU, manual settings are probably the way to go. You could however just put any CPU related settings back to default after enabling the XMP.

As far as i remember my ASUS ROG Maximus VIII Gene did nothing funky with the CPU settings upon enabling the XMP, but this might be something introduced with one of the later BIOS version (with Kaby support).
