Best DDR4 on the market at the moment for speed/latency/overclocking?

What's the best ram around at the moment?

I have ordered a 4x8GB kit of Corsair 3600MHz with 16-16-16-36 timings that seemed to be the best combination of frequency and timings which should lend itself well to tweaking.

But I realised that I didn't do much research and still have the opportunity to change my order as that ram is on back order with my supplier.

What's the best memory around at the moment to get the best frequencies at the tightest timings?
 
Any specific kit?

What makes it better than the Corsair?

Any overclocking tests/results you can share with me?

My local supplier has quite a few of their sets...

3733 17-17-17-37
3600 16-16-16-36
3400 16-18-18-38
3200 14-14-14-34
3200 15-15-15-35
3200 16-18-18-38
3000 14-14-14-34
3000 15-15-15-35
2800 15-16-16-35
 
Found UK stock of the 3600 15-15-15-35 kit... so I've cancelled my Corsair order and ordered that one.

Should be a touch quicker than the 3200 14-14-14-34 kit at standard frequencies and possibly have a touch more overclockability as the ICs might be a little bit better.

It was only about £40 more than the Corsair too.

Not for Z170... X99 & BW-E

I haven't updated my sig but I no longer have that PC.

It's now Asus Rampage V Edition 10 & 6950X
 
Nice :)

I'm going to stick with the 3600MHz C15 kit though as it's a slightly newer release and it shouldn't have any trouble matching the speed like in your screenshot.

2x G.Skill F4-3600C15D-16GTZ


Good to see 3400 at such good timings... those are practically the stock timings for my current 2133 kit... although I've improved on it for now.

It's a 8x8GB budget kit i bought for my 5820k to go in my home server with 64gb for VMs... Kingston Hyper X Fury Black 2133 @ 14-14-14-34-2T

While waiting for my new memory, I have it in here and I did some tweaking. I managed to get it to boot into 3200MHz @ 18-19-19-39-1T but performance was worse than 3000MHz which I have at 16-16-16-36-1T

Not bad for something bought only for cheap large volume :)

I'm not mixing though... they're both the same 2x2x8GB G.Skill 3600MHz C15

I assume you mean mixing those with the Kingston? I never had any plans to... the Kingston is only in here at the moment because I didn't have any other DDR4 to hand and wanted to get the right stuff which appeared to be on back order. Once the new stuff has arrived - these Kingston sticks are going back in my server.
 
So far not so good.

Memory completely refuses to boot at 3600MHz... even with relaxed timings. Even with 1.5V!

3400 @ 15-15-15-36-2T 1.35V = no problem
 
SA at +0.35V Offset

IA @ 1.4V

On auto, it boots... but only at 2666MHz.

Enable XMP and it won't boot at 3600MHz but automatically sets the timings to 15-15-15-36-2T @ 1.35V

I've reset everything to default and tried enabling only XMP... no boot.

I've updated to the latest 0801 beta bios and no boot.

3400 @ 15-15-15-36-1T @1.35V = no problem.

Tried with only 2 sticks = no boot.

Yes... it is with the rig in my sig... so 6950X & Asus Rampage V Ed 10
 
Got those voltages wrong.

CPU Input voltage = 2.0
SA = +0.4V (1.4V total)

3400 @ 14-14-14-34-1T = no problem!

3600 @ 19-19-19-49-2T = no boot :(
 
That's where I'm going at the moment :)

Looks like you might be right about that... 3600 is a complete no-go.

But at 3400 I'm stable at 13-13-13-34-1T @ 1.5V

Now trying 12-13-13-32-1T @ 1.6V which has booted - just about to run superpi to check.

Then I'll go for 12-12-12-28-1T
 
OK - I tend to go for best I can get then possibly back down a little for 24/7... but I'm happy with the feel of 12-12-12-28-1T... it's nice and snappy for usage - good reduction in latency.

Stable boot so far, just loading superpi while I test this.

I tried 11-12-12-28-1T to see and it won't POST at 1.65V - I'm not pushing the voltage any higher than that... so looks like 12-12-12-28-1T @ 1.6V might be good.

I'll also try dropping to 1.55V if this proves stable.
 
Perhaps that's the issue then.

I have a 4x8GB kit of Corsair sitting here in its box - they still posted it even though I cancelled the order. I'm tempted to try it and see if that can boot at 3600MHz.

At 3400MHz I have 13-13-13-32-1T stable at 1.5V which I'm quite impressed by. I was hoping for 3600MHz at 15-15-15-36-1T or better, but 3400MHz at those timings will be quicker.
