Just saw this, will get you in the list as soon as I get a bigger break;) Back to work for me:(

Updated.

2600k is amazing for over clocking ram.

How so? I've run a 2500K and a 2600K with both 4GB and 8GB high speed sticks, and P67 isn't nearly as good for overclocking ram as 1366 or 1156 was IMO. The reason? Multiplier overclocking only. There is no way to fine tune your ram. You are stuck with a handful of dividers, and there is no BCLK to tweak a notch or two to squeeze every ounce of performance from your sticks. Tweaking latencies are also problematic because of the jump. You may be able to run 1600 at CAS 7, but you may end up having to skip CAS 8 altogether because you are using dividers only. I'd like to hear your reasons for thinking it is so good, because I just don't see it. Don't get me wrong, as I like the platform for the raw processing speed, low power and temps, but memory is not it's strength by a long shot.

cdawall | 1640mhz | G.Skill Tridents 2000 CL6-7-6-22 | 1.66v | 1.19v | Core i3 560ES

i think VTT is correct will double check shortly 1.19v not 1.3v

I see it as being better because overall performance is better. 2000mhz DDR3 on X58 has much lower bandwidth and latency compared to 2000mhz DDR3 on P67 when cpu and bclk is the same.

I'd rather have higher bandwidth and lower latency than more overclocking options that don't perform as well.
 
No AMD?
all i see is Intel...

What is VTT?
Same as NB volt in AMD?

Not sure about AMD but on Intel I think it is for NB.

You have a point on the level of performance. I've been amazed by my sticks at 1866 on Sandy Bridge. Thing is, everything beyond 775 has ridiculous bandwith.

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.
 
Not sure what is going on with my ram but I can get a CAS5 at 1600mhz or a CAS6 at 2000mhz but and the latency score is very low however when benchmarking my bandwidth is very slow... Looks like my ram works best at CAS7.
 
^ Post some screens and scores please. Those timings seem incredibly tight for those frequencies and you claim strange results...definitely seek more info here. Link us to your exact PIs too...
 
@ sneekypeet, I edited my previous post to the format you wanted, page 7.


I've had a hard time going from 3.85 to 4.0 or 4.2 with my GSkill Tridents trying to keep mem at about 2000. I'll get 2009, 2005. Having only tried 1.65v on sticks, stock is 1.6v.
This x58 system is new to me. I have had hard time with 21 multiplier with the i7 950, it seems to like the 23 better.

Having very few mem setting options is frustrating.

Any thoughts on getting past 3.85 stable would be appreciated.
 
I do believe 8-9-8 for the tridents at 2000 is a bit tight, considering you are using stock volts.

Updated.... Cdawall, can you add the right timings to your listing? Post #153

Fixed sorry was thinking kit timings for some reason

I posted screen shot and info before your post of cas5. Out about right now... Will post cas6 @2000mhz later on. Latency is fast but overall bandwidth results for bencmarks I have tried are low. Maby its a glitch with benchmarks. Passed windows 7 diagnostic memory test. Stock air cooling.
 
Your system is bugged. check Windows System Proeprties page..I have a feeling it may tell you only half of your ram is actually available. When the memory controller is pushed a bit too far, this is what happens...you bandwidth figures are 1/2 what they shoudl be, so something is definately up there.

I will do that.

CPU-Z and MaxxMem(2) show 6 GB.

The benchmarks do show fastest Memory latencies however the bandwidth portion of the benchmarks is low. I'm hoping it is just a glitch with the benchmarks.

try running memtest before windows i honestly dont think you are running cas5 like cad said you are not putting off the results for it in fact my little i3 has better results dual channel with cas6 than your tri channel cas5

I did a google search on this and quite a few things popped up about problems with MaxxMem2 and other memory benchmarks when benching over clocked low CAS DDR3.

I ran the Windows 7 diagnostic memory test and no problems.
 
Here is CPU-Z CAS6 @2000mhz I'll post more details soon.

http://valid.canardpc.com/show_oc.php?id=1677166

System properties show 6GB of DDR3 but only 2GB available. Not sure what is going on. Seems stable. I ran windows 7 memory diagnostic without any problems and I'm getting ready to run memtest86+ a few times.

Once I get full 6GB up and running my bandwidth scores should be much better. Maby it's possible that I am exceeding the bandwidth limits of X58???

Ran Memtest86+ v4.20

Still shows cached 2gb of ram. Does show all of the ram but only 2GB cached being tested. Unable to change the amount to be tested. Not sure what is going on.
 
I've spent the last few hours reading up on why all of my ram is posting up during memtest86 but does shoe up on CPU-Z and MaxxMem benchmark.... It's because the ram is not tuned right and my MB boots up with the amount of ram that is stable. Not sure if this happens on all MBs...


Anyways I'm working on finding stable settings in which all of my 6GB of triple channel really is running. Please get rid of my results that I posted sneekypeet.

Once I get my ram running properly I should be able to have much higher bandwidth performance even if my Latency settings are lower than what I posted.

Everyone should look closely at their RAM being tested in Memtest86 to ensure all of the ram in slots is stable you may be able to post cpuz screen shots and run benchmarks with all the ram appearing to be working but it really isn't. (That was my case)

It's not the motherboard, its' the cpu's memory controller.

Basically, your ram will more than likely work at those timings, but the controller will not. It took one stick, and stuffed it into the "4th" channel. It was working in single-channel mode.


Oh, didn't know there was more than triple channel on Intel?

:laugh:

This mode provides the most flexible performance characteristics. The bottommost DRAM memory (the memory that is lowest within the system memory map) is mapped to dual channel operation; the topmost DRAM memory (the memory that is nearest to the 8 GB address space limit), if any, is mapped to single channel operation. Flex mode results in multiple zones of dual and single channel operation across the whole of DRAM memory. To use flex mode, it is necessary to populate both channels.

I read that and i don't think I'm experiencing flex mode. I am running triple channel ram and when my sticks don't have enough voltage only the slots with enough voltage show up. Triple channel requires more stability and my problem was related to voltage adjustments.


As i tweaked my vdimm voltage and vtt voltage i picked up all of the 6gb of ram. No flex mode configurations in my set up. I'm running 3 sticks of ram designed to be ran in triple channel mode.
