Ram Tweakers Version DDR3

Yes, and a lack of memcontroller voltage makes the "flex" channel the only one available. You simply need more controller volts. *shrug

Stick in 4 sticks, and you can get triple-channel, plus the flex one.

 

[SonDa5]

Just a thought. Maybe we should split entries into dual and triple channel configurations. There is simply no way for triple channel to match the raw speed of dual.

Again i woulld like to see this along with a maxxMem category for overall bandwidth speed and latency.

That would be quad channel?


I will try it out but I'm positive the overall bandwidth speeds will not be there. 4gb is physically less ram to push than 6GB. I think overall bandwidth speed and performance is more important than the speed of the ram.

As far as marketing is concerned, yes. AFAIK no system available retail can run true "Quad Channel"

As for the kits sold as quad channel, its a misnomer, its dual dual channel (think dual core with HT, yes there are 4 but not in the true sense of operation)

AMD server is quad channel G34 to be exact.

Let me rephrase that then Noting outside of future products or the server market

good call was just letting you know also other guy needs to figure out that it was NOT working at CL5 or CL6 same thing happened on older P35/45 boards

Who is other guy? Me?

If so I already posted I found a glitch in my system. This is why people should post some bandwidth benchmarks and run memtest86x with carefull attention to the amount of ram that is cached for the the test and the overall bandwidth.

I can get all of my ram to work with CAS6@1600mhz but I have to use 2T instead of 1T. Performance wise this is a sweet spot for gaming with decent bandwidth for general usage and very low latency.

the entire amount of ram is cached

I think you're not understanding each other.

I agree.


Explanation for those just tuning in.


I tweaked my ram and was able to get low timings@specific speeds. I had a problem that not all of my 3x2GB sticks of ram were working. CPU-Z and MaxxMem benchmark didn't pick this up. I noticed the problem when I checked my Windows 7 CPU specifications and it showed that I had 6GB of RAM but a lower amount actually being used. I ran Memtest86+ v4.20 and it showed that all the memory slots had the right amount of RAM but the test was running a smaller amount "cached".


So I tweaked my memory Vdimm voltage settings along with Vtt voltage settings and my missing ram came back. In my situation I have come to the conclusion that my voltage settings along with ram timings were unstable and I worked on each till I got all of my ram back along with stable over clocked timings and speed.

Say I take a set of 2x2GB sticks of tripple channel ram and I configure them with another exact same set of ram in flex mode. Isn't this a form of quad channel ram?


I'm thinking about doing this if I can run 2 of the faster 2x2GB triple channel sticks in flex mode at faster speeds.

NO, this does not work. The flex channel is slower, as seen by your benches, and the memory in that channel is onl used when the other memory is already occupied with data.

So no, it isn't exactly quad channel. It's triple plus another channel for overflow.

I didn't configure flex mode. I configured 3 sticks of matched ram in the proper slots for triple channel mode.

On my MB there is a specific configuration of ram sticks to enable flex mode in 2N mode.

As I have posted before i'm positive my problem was voltage related. I never ran flex mode.

its not that you configured the stuff to run in flex it was unstable and thats what the memory controller does its. think of it as an oh shit mode

I like to be able to "play" with my hardware, and P67 seems to not give me as much flexibility to tweak. That's my only complaint about the platform.

Me too. The overall performance of SB on P67 is enough to make me want to sell my X58 hardware and go SB now.

X68 is righ around the corner and hopefully it will offer more memory adjustments.

I wish DFI was still making MB. That would help me make the move to SB much quicker.

 

[SonDa5]

Having very few mem setting options is frustrating.

Any thoughts on getting past 3.85 stable would be appreciated.

X58 has many memory settings.. At least on my DFI X58 JR.

One thing that I notice is high on your CPU-Z screen shots you posted is your NB frequency. Look in your BIOS settings for uncore frequency settings which is directly related to the speed of your NB frequency.

I've read that it's best to not let this number match your cpu speed. From my own experience at running ram at 2000mhz it is hard to run NB frequency above 4000mhz.

With the i7-950 and that 23x multiplier you should be able to run a nice warm 180'ish bclk and get your memory ratios to give you a 2000mhz+speed on your ram... Try lowering your uncore ratio to lower NB frequency and that should help your memory be more stable at higher speeds. That has been my experience.

Also on my mb when I lower my uncore ratio frequency it allows me to lower Vtt which helps lower temps on cpu.

So then it never was in flex mode.

It was in flex and had ALL of the telltale signs of it. YOU just didn't put it there.

 

[SonDa5]

I tried 4 sticks of dual channel DDR3 and configured them in triple channel flex mode and it wouldn't boot.

Same 4 sticks would boot in dual channel mode with 2 sticks or 4 sticks.


I was hoping to enable the triple channel flex mode for all 4 of the dual channel sticks... oh well. At least I know I can run dual channel triple channel ram in my slots.

Got a chance to tinker around with some Elpida Hypers, they don't do too shabby....

when you get it all sorted add some voltages, so I can list it with the rest of them.
