Mounted in ASUS ME-Z, looks great and with Airflow fan to keep them cool.

Overclocking DDR3 3065mhz at 11-14-14-35 2N

This maxes out my 3570ES memory controller so maybe the sticks have more in them. Hopefully my retail CPU has more in it. These sticks have massive overclock potential. More results and bench marks to come. Others using Tridents post there results here too for comparison.

Here you go CPU at 5.9, DDR2800 Max mem. I am half way through tuning for Pi32mb. So I can still improve on this at 5.9. I am also going to do the same tuning at DDR2933+ which is the next memory strap, then tune BLK more for further speed. 6ghz Pi32 is possible for sure.

what dram voltage for 2333?

ive seen the samsung green hit 2933mhz with 1.7dram i think

2333mhz stock is 1.65v. I have not tested lower than this. Low voltage is not what I am trying to do.

2933mhz is good but as you know it depends on timings and tuning to determine what voltage is needed to make the RAM stable. e.g Ram overclocking for maximum mhz vs ram tuning for maximum performance at a certain speed or infact no tuning at all just max mhz. Other system components including CPU IMC is critical to RAM overclocking and perf. too.

8-Pack, quick question if you will.
What voltages (other than DRAM) are you hammering to get high RAM frequencies, what is required to give the IMC a kick in the nads? VCCSA/VTT?
 
Not hammering no. Infact my Retail chip does not like high VCCIO at all. Each chip is different. My ES likes around 1.35v VCCIO and can run incredibly tight timings but not as high frequency, but big BLK like 112-113. Retail chip hates anything above 1.2 VCCIO cant run quite as tight as my ES but can run higher mhz. BLK on my Retail tops at around 106.5 which is poor really. PLL both like lower than default 1.6 - 1.7, Data ref both like 0.495v, VCCSA 1.2-1.25. Skew driving voltage needs to be very low to clock RAM around 0.40v All the CPU/PCI scews are at negative full settings to allow as much BLK play as possible.

With clocking DIMMS on Ivy the Transmitter Scews are essential and you have to play with these. My Trident like 4 and 5, Samsung Greens like 3 and 4. Get the correct values and previous clocks that fail mem test often pass without adding voltage.

Hope this helps. I am gonna do a comprehensive thread on clocking DIMMS on MVG as soon as I get time.

EDIT Further testing on my retail CPU shows it can actually reach high BLK but not with high memory mhz its capable of like 112 BLK but only @ around DDR 2600.

I ve been reading reviews that say that heatsinks on DD3 are not really needed and are mostly for aesthetic reasons. Quite supriced that you not only have the heatsinks on the ram but also the cooling mount for them. Do you notice any difference with/without heatsinks/cooling mount? I ve ordered the 2400mhz version as i think will offer better performance/price value and as you said this memory does overclock quite well. Am planning on removing the heatsink and possibly raise the CPU cooler fun so that it doesnt interfere with the memory.

8Pack will have a more accurate answer i'm sure, but to me it seems you only really need heatsinks on DDR3 when pushing DRAM voltage above 1.6-1.65v. There are crazy people that push 1.7-1.9 with air/water cooling.
Put it this way, if i slap my DRAM voltage up to 1.6v on the Samsung Green (it's 30nm so probably not the best example) and load up the PC to max and touch the chips, they're cool to touch.

Thanks for that, you're very helpful 8Pack +1000 rep.

Is VCCIO the same as VTT yes? There are those that say VTT should not be touched and VCCSA should be raised and those that say the opposite. I've found that VCCIO has helped clock my memory higher.
 
No VCCSA is the system agent. SA= System agent. This should remain the same with SB for sure but with Ivy the testing done by all the top Overclockers and engineers alike have shown a bump up to around 1.2 - 1.25 is ideal. For top memory and CPU clocks plus system stability.

VCCIO is the IMC voltage amongst other things similar to VTT/VCCSA on X79 but not the same.

The fact you have found VCCIO has helped clock your memory higher has answered your own question really!!! lol Keep trying this to stabalise / attain higher DRAM clocks. Like I have said previously though some CPU's like it more than others.

If your planning on running tight timings, high voltages, Overclocking out of spec stuff leave the heat sinks on. All PC components benefit from being colder to increase stability and life being run out of spec. Memory is the same. Your worried about warranty too you need to leave the sinks on. Any evidence they have been touched invalidates the warranty.

I personally run a 12cm over my dimms while clocking to ensure temp is not an issue.
 
Hi there

This is not released yet, but due next week fingers crossed, so yes we shall be selling it. :)
