So, when is the water cooling unit going to be released?
I think so too, DDR3-2350 8-9-8 with 3x1GB Dominators 1866C8. I'm curious to see what he can pull off with 3x2GB 2000C7GT, though.
Most 2000C7GTs should be very close - the kit I'm using in the video is from exactly the same batch that was sold in Corsair Store on the first day of availability. It's really the CPU and cooling that makes a lot of difference above DDR3-2200. I went through probably 10 x 965XE to find only 2 that are, let's say, decent...Those look a lot better than my GT's, I think, but I'm not certain. I've never been over 2260, but maybe I haven't tried hard enough.
Within days another batch of 2000C7GT is to land in the Corsair Store, and waterblocks should make it at the same time as well. We should also have TECs available in the store within 2 weeks. Sorry for delays - we're making sure all is tip-top before we release it into the wild.
I appreciate your interest and patience... It's all almost here...
Good job, guys! Thanks! But I want to see more, more, gimme more
If loosening latencies to 8-8-8 does not gain you anything, then it's most likely not the DIMMs - Elpida Hyper's I/O circuitry allows for DDR3-2133+ at 1.65V VDIMM, but you will need to give core a break and run it at CL8. Issue is, to absolutely max it out, we need even better platform than X58, and Uncore capable of running routinely at up to 4.5-5GHz without massive voltage increases... But then next up in line is the memory bus, or more precisely layout of traces on memory bus, and BIOS - on X58 we see more cases of memory controller dropping channels at very high speeds after unsuccessful memory training routine when it can't align CMD/ADD/CTRL signals correctly across all the DRAMs, ranks and channels (e.g. dreaded "where's my 2GB gone?" issue), and even when each DIMM is capable of much higher speeds, and manually playing with RTL settings doesn't help anymore.

8-8-8 don't gives me any advantage and the Memory don't scales with more Voltage, I think the problem is the memory controller.Good job, guys! Thanks! But I want to see more, more, gimme more

CPU runs nice, up to 4,6 Uncore 32M stable on Cascade but with Samsung ICs 1075 CL8 was also the max. have tryed a lot of combinations with the EVGA X58 Board but no possibiliy to get over 1053 32M stable
hope we will get a nice D0 in the next weeks, so I can push the memory higher, but unfortunatly the 2000C7 are no more here...
Great work Bachus, really impressed. But uh Bachus, damn what a hard job you got testing all these ram modules with your 10x i7 965's, its a hard life eh but someone got to do it
Hey you don't want to sell me one of them 10x chips you got lying around do ya, ten is a bit greedy

Need some advice.
which one is faster lol Sorry,
7-8-7-20 1866?
8-8-8-24 2000?
There both the same price but the 1866 is in stock. Does it even matter?
For Elpida, 2400+ CL7 is not that hard. It depends on cpu.
I can confirm on DFI UT X58-T3EH8 with 2/27 beta bios that ADDR/CMD Bus VREF bios option did help me get single super pi 32m stable with ADDR/CMD Bus VREF = 95 when it wasn't stable (reboots) with default ADDR/CMD Bus VREF = Disabled @DDR3-2140Mhz 7-8-7-20 1T with 1.61v CPU VTT and 1.875v VDIMM.
Gary you mentioned Round Trip Latency (RTL) tweaking too, and I noticed that RTL value in CPU Tweaker loosened up when I changed ADDR/CMD Bus VREF from disabled to enabled with 95 value. RTL changed from 57 to 58 after enabling ADDR/CMD Bus VREF with value of 95.
ADDR/CMD Bus VREF disabled where RTL = 57
ADDR/CMD Bus VREF Enabled = 95 where RTL = 58
interesting indeed !

Looking forward to seeing the water blocks, thank you bachus.
Best I can do for now with new found ADDR/CMD Bus VREF tweaking (set at 105) @DDR3-2209Mhz 7-8-7-20 2T at 1.92v vdimm bios set (1.925v real DMM).
@DDR3-2209Mhz 7-8-7-20 2T at 1.92v vdimm bios set (1.925v real DMM)
Validation is at DDR3-2209Mhz just cpuz clock momentarily jumped to DDR3-2212Mhz
@DDR3-2286Mhz 7-8-7-20 1T at 1.875v vdimm bios set (~1.880v real DMM)
Still not close to my best I did when i first got my GT set with DFI UT X58-T3EH8 with 1/23 beta bios.

My qpi is set at 1.6 in the bios, altho my volt monitor says 1.54, anything under that i cant boot at all..
Got my drammv 1.65, cant get them to run on 1T tho, should i set dramm volt higher to run at 1T ?
is there much difference between 1T and 2T ?

Apple IPad 2
Id try lower bclk with other divider to check if 1T and/or lower vqpi is possible, 200 bclk is a tricky setting.
Is this ram still worth it? I notice that prices have plumetted on DDR3 kits lately.
For example I can get OCZ Platinum DDR3 2000 (9-9-9-30) for $310 canadian dollars. That's around $230 US.
It seems that all DDR3 except for corsair and kingston is much cheaper at the moment.
How much of a performance hit should I expect if I run 2 of the 6Gb kits?
For example, would I be able to run 12Gb @2000MHz 8-8-8-24 on an EVGA Classified board?
Or am I pretty much guaranteed to have to run slightly slower than that with all slots populated?
You can lead a nub to water, but all you'll get is wet nub.
I was reading the anandtech article on the classified and they stated that that motherboard is better at having all memory slots occupied. You should get much better memory bandwidth than just 3 sticks atleast....

I would like to know as well. Their website says availability on the week of the 18th. I've received no email notification nor have i seen the website show that they are in stock.
