I want MORE !! MOAARRR :-D

If you have an extra fan & a ziptie, throw it on the RAM. That way you won't have to worry about it, and the extra airflow around the CPU VRM won't hurt either.
I have a vintage Core2 Duo gamer in the basement with actively cooled DDR2.


If Star Citizen can use 40GB of RAM, it has a memory leak that the developers need to fix! Just sayin'

Have you tried 3600 1:1 yet?

This. That doesn't sound right....

I mean, you CAN put a fan on it, but, it's not going to get you anything more (except noise).

They DID have a leak at some point - They even warned players about going to those places where memory usage would just keep building up.
Something about "gas cloud tech" that didn't play well...

Most people in the forum are also saying that 32GB is more than enough.

Have you tried 3600 1:1 yet?

No - But I'm working on working on it

My old rig was noisy as hell - So I'm not adding extra fans to my current rig.

If anything extra needs cooling, then it will be included in the water loop at some point.

 

[Zerileous]

Ehh, just monitor your temperatures with something like HWiNFO64 while you're stress testing your memory and it will be fine. I run 4 sticks in a water cooled system no trouble. Unless you're going over 1.4v you won't have a problem.

Okay, back in town for a short while.
This will apparently take me quite a while to get done - I hope you guys are okay with that.

First things first - I need to get your "namings" translated into Gigabyte BIOS language.
Having trouble locating the options that needs to be modified

Watched a video with this Buildzoid dude on YT - That video went WAY over my head within the first 20 seconds (and never came back down).

So in Gigabyte BIOS language - What do I need to change?
I know that I need to input "1800" somewhere and "3600" somewhere else. But exactly where, I don't know...

If you guys need a picture of the BIOS, please let me know.

Thanks

 

[JLK03F150]

I think I watched that video several times! lol Lets see if these help, should be very similar.

This is the system memory multiplier. Your RAM's XMP multi is 40, mine is 36 but overclocked to 37.33. You want to start with 36 & then work your way up to whatever 1:1 max you can get.
DDR3600 has a base frequency of 1800.


This is the Infinity Fabric or FCLK Frequency which will be set to 1800MHz to match the DDR3600. Mine is at 1866 because of my overclock.


Manually set you DRAM Voltage somewhere from 1.35v to 1.40v.


Go into Advanced Memory Setting to Manually set your Primary timing. Match them with the setting from the XMP column of the SPD tab in CPUz. BTW, my Standard Timing Controls are all on Auto, but you want to enter yours there.




I hope your BIOS is close enough to mine that you find this helpful. Let me know.

THANK YOU !!!

PC is booting with these settings.






[EDIT] - Just tried with 1900/3800 - That was a no-go with the above voltage/timings.

[2nd. EDIT] - Reverted back to 1800/3600 - Aaaand I'm leaving town again shortly.
I'll get back to you guys as soon as possible.

[3rd. EDIT] - I'm really screwing this one up... Sorry guys - I uploaded the wrong image with Voltage settings...
The one you saw said "auto (1.2V)" - That's an error - It should say 1.4V.
I don't have a photo of it..

 

[JLK03F150]

Did you have time to do any before & after testing? I saw gains in just about everything I tested after fixing my 1:2 RAM overclock.

Erhhh.. Totally forgot to test BEFORE changing anything

BUT - I can enter the old values again and run aida64.

What tests do I need to run?

1900/3800 probably won't work at standard voltages or won't work at all because of 4 memory modules. 1800/3600 is not much slower, but much easier to set. Once you stabilize everything, you can check tighter timings at 1800/3600 like CL16-18-18 1.35V and later CL14-17-16 1.45V. 3600 CL16-18-18 1.35V is actually XMP profile for the same Micron B IC in Crucial Sport series RAM, so it should work.

 

[MuHcOw]

1900/3800 didn't work at 1.4V
Let's say I would really like to have it working (disregarding that it might be impossible) - Would I have to apply even more voltage and looser timings, or are there OTHER settings that needed to be checked?

OC the CPU first??

 

[MuHcOw]

Back again!
So, now what? - Timings, frequency or voltage changes??

Or something...

Right now I have this:

I could make changes to the timings as you say, but shouldn't I try to push the frequency a bit higher first, or??

 

[JLK03F150]

IMO you should refer back to Woomack’s posts #6, #36 & #50. He has recommended various primary timings, volt & frequency ranges for you to try. In case you didn’t know, he is a memory reviewer and if he offers specific information or advice it’s because he probably tested those settings while doing a review.
I know I’m grateful for the info he provided me for my 32gb kit.

 

[MuHcOw]

I'm in no way ungrateful - It's just that people have been suggesting Voltages, Timings and Frequencies kinda random (that's how it feels to me).

I'm just not sure if I should work on Voltages, Timings or Frequency as my next step...

What's the normal procedure?

 

[Woomack]

1. Check at how high frequency the RAM works stable at relaxed timings and higher voltage like 1.50V. In your case, relaxed main timings are 18-19-19-19-39 (so exactly as you have right now), as it's enough for ~4266+ on your RAM, and you won't ever run it like that 1:1.
Go as high as it boots, and run a stability test. If it passes, then you have your max clock; if not, then lower the RAM ratio by one and test again.
2. Once you find the max clock, start checking timings. It will probably be 3600 if you use 4 memory modules. Since it's Micron B IC, then focus on main timings and leave secondary/tertiary at auto as they won't help you much (or leave it for the end).
Start with CL and later add other timings from the main timings list. Almost only CL reacts to voltage, so to find the lowest timings, you have to focus on CL.
To make it easier, you can set CL and wCL (twCL) at the same value. WCL = write, CL = read. CL has to be equal to or higher than wCL.
3. This RAM will probably work at 3600 and CL14-17-17-17-37 1.45V, but it's not a rule, so if it doesn't work like that, then try 14-18-18-18-38 or 16-18-18-18-38.
Since various motherboards react in a different ways on some RAM, you have to check it yourself.

Usually, motherboards already set optimal memory controller voltages and everything else for a 3600-3800 RAM clock, so you can focus on CPU and RAM and leave everything you aren't sure at auto. For the 3600-3733 memory clock, you don't have to adjust anything other than the memory voltage manually.

In general, it looks like this:
1. First check max CPU OC as it affects the PC performance the most
2. Check RAM max frequency as it gives more than additional timings (especially on Micron-based RAM)
3. Adjust additional settings and timings to shorten the access time and lower power usage (if you care about it)


I don't have detailed settings as I was reviewing Micron B kits a long time ago, but I found some results on X570 motherboards:
128GB / 4x32GB Crucial Ballistix 3600 CL16-18-18-39 1.35V @3600 CL14-17-15-37 1.50V (the same IC but in dual-rank modules)



32GB / 2x16GB Crucial Ballistix MAX 4400@ 3733 CL14-17-16-39 1.45V



32GB / 2x16GB Crucial Ballistix MAX 4000@ 3733 CL14-17-15-32 1.45V



as a bonus so you see how it performs at a higher clock and 1:2 ratio, 32GB / 2x16GB Crucial Ballistix 4000 MAX@ 4800 CL18-21-20-36 1.50V

VERY NICE post !!!! - Thank you.

Since I won't be able to go high with a 1:1 ratio and 64GB RAM - Should I set it to 1:2 instead and then see how high I can take the Frequency?
Cause with a 1:1 ratio (1.5V) It doesn't seem I can take it higher than 1833 (unless I'm doing it all wrong (again))...
1833 also works with 1.4V

 

[Zerileous]

It depends on what you want. If you want the best overall / gaming performance you want to stay at 1:1, but you can certainly see what you can do at 1:2 with the ram just to run some benchmarks or get more comfortable overclocking memory.

 

[Woomack]

4x16GB 1:1 will go up to ~3866 max (if you have luck), but usually 3600-3733 max. 1:2 will go up to ~4133-4266, but as you see on my screenshots, even 4800 has significantly worse latency which, in games and some other types of programs, is more important than the memory bandwidth (of course, if we count 5-10GB/s and not something like 20GB/s+).
2x16GB 3600 CL14 1:1 has similar results in games as 2x16GB 4600 CL18 1:2. However, everything below 4600 will be slower, no matter how you set it ... and as I said, you will be limited to maybe 4266 because the memory controller can't make much more with 4 memory modules. So again, focus on 3600-3800 CL14/16, as this will give you optimal results at still low voltages.

I did this at 1.5V

This one is the standard XMP one with those loose timings:


Am I doing it wrong???

 

[Woomack]

It's fine. Higher frequency = higher bandwidth, but you can see 7ns lower latency. If you check my screenshots then you see that you have about the same bandwidth, but additional timings can give you 2-3ns lower latency. It can be also a matter of the software in the background or something else.
You can play with additional timings, but if it's stable then I would leave it like that as you won't make it much faster. As I said, maybe 2-3ns latency or maybe 1GB/s higher bandwidth.
