Dark Pro 8 Pack 3200Mhz ram @ 3466Mhz settings - Will a mod please move to the ask 8 pack section.

Hi Mate.

I recently bought the Dark Pro 8 Pack 3200Mhz ram.

Haven't installed it yet, but I randomly found this video.

To run the memory sticks at 3466Mhz do I have to put in the timings you have in Memtweakit on the left?

Primary timings:
16 16 16 16 38 1T

What about the secondary timings?

Dram voltage?

SOC?

---

Current settings are SOC at 1.1v and CPU @ 3.8Ghz - 1.35v.

If you search the internet for the stilts settings these are the ones I used to use for 3466c15, luckily they were built into the BIOS of my motherboard so just chose them from a menu rather than typing them in.

A quick way to do it is choose DOCP and then change the RAM divider from 3200 to 3333 which gives you 3333c14 and similar performance on 2 x 8GB. I run vcore 1.25v, soc 1.135v and ram 1.4v.

Do some testing to see if the changes give you a useful improvement.

Cool. I'll give it a go when I instsin them.

These are the settings I use also. Work a treat.

Bottom left 3466 timings are the ones you want.

Thanks!

Did you have success with the 3600Mhz settings?

HeX · 12 Apr 2018 at 19:05

Never tried the 3600, you have to be very lucky with your IMC to hit that speed and I was happy enough with 3466.

What volts did you use for SOC and DRAM at 3466Mhz?

Also I see you used Intel Burn test. Is that a good way to test your ram stability too?

Also which is faster the 3200Mhz DOCP settings with it's default tighter timings or 3466Mhz with loser timings?

1.175V SOC
1.4V DRAM

With Ryzen the faster clockspeed the better, as the Infinity Fabric bus is linked to memory speed.

IBT is my preferred test for whole system stability, it'll very quickly fall over if anything isn't solid. If it can pass 20 loops of that on V.High I know it'll pass anything.

True but it’s serious marginal gains over 3200...

Stilts profiles, but more bios dependent on Ryzen - the sticks can probably easily do more.

Software dependent. There can be quite a big gap between 3200 and 3466:

Wow!

I have just managed after a lot of fiddling yesterday to get my pc stable at 3.8Ghz and 3200Mhz on the ram.

It seemed introducing faster ram made my previous stable cpu settings unstable.

I stabilised the CPU at 1.36xxx volts (up from 1.35v), verified the ram was stable by playing Origins for 4hrs with the CPU at stock but ram set to DOCP.

When I turned both CPU OC and RAM OC on together the pc would lock up within about 20-30 mins.

It turns out I needed to up the SOC voltage a few notches.

---

I fear if I attempt to hit 3466Mhz on the ram, I am going to need a lot more CPU voltage?

On the other hand it might be as easy as bumping the dram volts to 1.4v and pushing the SOC voltage a little bit more.

---

From those benchmarks it looks worth it however.

CPU is already hitting 68c under 100% load in Prime.

HeX · 16 Apr 2018 at 11:04

Don't get me wrong some games/programs you're probably not going to see much difference between 3200/3466, but for those that are sensitive to it you can get decent gains.

If you go higher it'll more than likely be SOC voltage you'll need to bump up, anything up to 1.2V is fine. Try for 3333 as a stepping stone, lots of people have found they can just load the XMP settings for 3200 then change the memory speed to 3333 and set volts DRAM to 1.4V and it'll be fine. If not start incrementing your SOC voltage until you hopefully hit stability again. If you get that solid and you have SoC headroom, give 3466 a go.

Just remember to save your current stable 3.8/3200 profile before you start fiddling again, that way if it all goes wrong you can at least fall back to known good settings

@HeX

Can you link to the article you got those screen shots from?

Thanks

You realise what you are describing is Ryzen, right?

I had an 1800x, clocked up to 4.1. I can tell you my experience of using it is anything over 3,200 on mems maybe 3,333 is marginal. The only thing you will notice is how often you have to boot in to the bios.

I sold it, now I have an 8700k running 5.3 with 4,133 memory... incredibly easy to set up in comparison

Yea. I hear ya. Ryzen is very rough round the edges.

It's gonna take a few iterations and a few years to work it up to the smooth experience it should be.

I think I'm just gonna leave things be rather than continuously fiddle.

I tried the Stilts Fast settings for 3200 as well as the 3466 profile on my CH7 but they dont seem to pass the IBT.
I wonder if anyone with a CH7 and 2700x on here managed to use the Stilt's settings from the bios and have it stable?

8 Pack · 22 May 2018 at 12:39

So far for me CH6 better than CH7 for memory. I would wait for Bios to mature before trying to do too much in terms of tuning. I am also not really convinced by 2xxx series IMC being a big improvement right now...

Jumper118 · 23 May 2018 at 22:27

That is surprising. I find the ch6 rubbish compared to the ch7 for meme oc
