z97 Is here

Sounds like we will have a literal 3400 setting moving forward :)

Possibly higher on the boards aimed at pushing the envelope.

Hopefully this is an indication that DC's IMC will be stout .....
 
That ASUS Z97 WS has 3400 but only marked as OC so there is no change - "DDR3 3400(OC)/3200(OC)/3100(OC) " , as I said anyone can add even 4000 OC and it won't change much.
 
Hmmm...

My z87M OCF has advertised OC memory profiles in the BIOS ?

when set the stix run at said speeds with out pushing bclk up ?

I must be looking at this wrong as I thought you would be able to start pushing bclk at 3400 Mhz as a starting point ?

making 4k easier to obtain ?

This would really put the pressure on the IMC of the new chips
 
The OC nomenclature is, from my understanding, just there to note it is above Intel specs. You can set it there if the memory sticks and IMC can handle it. It has nothing to do with BCLK as you allude to Witch...
 
I see, will read up, My thought process was you would need to push the bclk to take speed higher than setting in BIOS

never was any good at overclocking memory, although I am contemplating grabbing a memory pot :)
 
No no... you are right. I am agreeing. :)

Assuming: multi works, sticks can handle it, IMC can handle it, set it to one of the highest memory multi/speeds then use BCLK to push it up past that point. :)

There may be more performance to be had with higher BCLK with lower memory multi/speeds though...that is not something I know however.

For example 167xmemory multi to reach 3200Mhz or 100xhigher mem multi to reach 3200.


Sorry I was vague earlier, LOL!
 
Yep,

Thought I was loosing it :)

My whole thought here is if the MB makers are advertising higher memory speeds all be it under the (OC) moniker, is this simply marketing and if not will this mean stronger IMC's on the Devil's Canyon chips.

If so, one would conclude world records are going to be broken

Have a friend who will be rocking the new OCF and DC in a few weeks
Should have some definitive answers to these questions :)
 
IB, IB-E and Haswell memory controllers have maximum memory ratio of x29.33. IB-E and Haswell have 3 straps 100, 125, 166MHz what means that:
-> 100 x 29.33 = 2933 MHz ( DDR ) <- this is max official memory speed for every Z87/X79 mobo and probably Z97 too
-> 125 x 29.33 = 3666 MHz ( DDR )
-> 166 x 29.33 = 4868 MHz ( DDR )

There were IB boards with higher memory ratio but these ratios were not working.
So when you set profile for higher clock then board will overclock bclk to required value and if needed will raise voltages.

ASRock OCF are easiest boards to overclock memory. Most settings are optimized or already programmed to change for optimal performance or max clock. You can adjust all manually but auto settings are usually best anyway.

IB-E is also running great with memory. I was able to reach ~3700+ clock on my 4930K+RIVE. The same memory on MSI board couldn't make more than ~2750.
It doesn't change fact that anything above 3000 has no point as current even best IC has to run at really relaxed timings to be stable what means that something like 2600/2666 CL10 or CL11 will be still better.
I don't think we will see any DDR3 that will be running at CL10/11 3000+. I mean like in mass production not single samples.

Yea, MSI has always seem to be memory weak, my x79 GD65 can't even do the advertised 2400 ,

3700 is rocking on a x79 ......... :thup:

If I remeber right 4400 and change is the world record,

I am thinking that will be broken at CompuTex if the new chips are in fact biined for the show, something tells me they will be
 
Right now there is little issue with new memory kits. Even though clocks are still high then as you may noticed 2666 are already CL12 and are based on a worse chips. If anyone is going to break world records then it will be on early Hynix MFR so probably cherry picked kits that some already stock for a while. Good were kits from middle of the last year. All in last half year are worse for max clocks. The same is happening with Samsungs. Higher density but lower max clock.

I had MSI X79A-GD45 Plus and I could make it run stable at 2666 with max clock up to 2750. That was with Hynix and Samsung kits but I couldn't make it run with PSC above ~2333 even though these kits were running up to 2800 on IB.

Actually on IB-E when you set higher clock then performance isn't raising. For some reason max possible bandwidth will be about 80GB/s while in theory should be 90GB/s+.
I was able to reach about ~75GB/s with Samsung kits @2800 CL10 ( tested in AIDA64 ).

I think I still have the highest result with memory on air on hwbot. My CPUs had too weak memory controllers and cooling memory with anything better wasn't helping at all. I almost burned one of my kits running it on dice and I barely made 10MHz better clock ( was some moisture in slot ).
Generally high memory clock is good only for max clock validation and nothing else, still some fun to make it ;)
 
No doubt about it, its all about the fun in getting there ...
even if it just to get a screen shot :)

got lucky and scored some cas 9 2400 and CAS 10 2666 PCS stix before they disapeared

Nice results on that MSI board, I have been beating my head against the wall trying to get to 2133 CAS 8 for my gamer using Team Extreem 2400 Cas 9 stixs , do you know whos chips are on these ?

Best I have been able to get is 2004 CAS 8

really have to loosen them up to get any higher
Thought it was the board, guess it is the operator .... XD

Aren't those hynix or samsung based?
 
Not sure, I will have to do some research, never really looked in to it as they are only for my gameing rig.
 
Team Xtreem, G.Skill TridentX and Corsair Dominator Plat. 2400 CL9 2x4GB or 4x4GB kits were only on Samsung but mixed IC. The same as 2600/2666 CL10. About the same IC series is in all of them. Some better some worse. Earlier kits were mainly on HYK0. Newer sometimes other IC.
Generally most HCH9 or HCK0 can't make 2400 CL9 ~1.65V. They are running on 2400 10-11-11 or 2600 10-12-12 but CL9 is much harder.

To make 2400 or higher clock on MSI board you have to use 125bclk+ strap. At 100MHz most kits won't even boot. I was using 166+bclk for 2666+ clock.

Thanks for the tip, I will give it a go..... :thup:
