damm the one day i don't check is the day it was out ahh all sold out

[DonFaygo]

Seriosly and I thought I lived here, three days pass and I missed out. Oh wel, I can wait a week lol

[firerx]

good for you! Welp, I'm kinda getting the run around from OCZ. Their standard answer for the Blade series release is 4 weeks. However when I talked to my Vendor, he talked with OCZ yesterday, and got a Next week ETA on my pre-order. So I guess I will see next week

[slim142]

730 euros 6Gb memory kits are sold out. Where is the economical crisis on this? I dont know what you people are doing for a living, but althought i can also buy this ram i find this price plain insane

Ofc i have to agree that they look sexy and that these would also look sexier on my evga classified board

I also ask myself that. I could save up and buy this RAM, but time is not right and that money just cant go to anything unneccesary right now. Oh well, good luck to the ones who will be enjoyning this RAM sticks soon

...and I thought I spent a premium with my CSX Diablo GTS...

[cstkl1]

just curious
the 1866 are using the same IC's
but are binned lower

is that because the IC's are inferior
or because corsair wants to make a wider range for the GT.

reason is the voltage of 1.65v for 1866 7-8-7-20

bro call ocz taiwan.
thats where the stock is
ask ure vendor to call them
they gave me a eta of 3-4 days.
but that was like a month ago.


but the price is the around the same as the gt.

[ChaosAD]

I would like to ask something else. Dont you guys think that Adata 2133X are better that the GTs, since they can run the same 2000C7 spec with lower voltage?

Andre's results is just one set among many and memory clocks also dependent on cpu's memory controller as well. So exact same memory kit may perform differently on different cpus. Also remember sub zero cooled i7 cpu will also cool memory controller allowing higher mem clocks than what you and I can achieve on air/water.

eh but the corsair were running with 12gb at 1866 CL7
so far havent seen any doing that

[darthvedor]

hi all,

Does any one know where can I buy this memory in UK.

Regards

[eva2000]

Again partly dependent on cpu mem controller and some extend motherboard/bios

You need to buy directly from Corsair, though bachus said somewhere here that the 1866 maybe availible in other places but nothing sure.

Ok so what you mean is that with Adata memory results are not guaranteed, while on Gts you get the performance no matter what.

The price difference between them are not much either.

[eva2000]

No i mean both brands may have varying results depending on how good/bad your core i7 cpu's memory controller is and board/bios. What really will separate memory will be amount of cpu vtt/uncore volts required and that is solely dependent on your cpu and board cpu vtt power/design > http://www.anandtech.com/cpuchipsets...oc.aspx?i=3502

I read the anadtech article. According to it, there is no way to run an i7 920 and 6Gb ram @ 2000c7, c8 maybe. Is this true? So the 2000c7 GTs are only for those with i7 xtreme?

[cstkl1]

eh no bro read till the end
he was trying to generalize
that qpi 4000mhz for rams at 2000mhz depends on proc imc/mobo and some even say depends on cooling

I conferred back with Gary on his results, he’s got three retail 920s in his repertoire (with a fourth on its way) and his results are erratic in this department too. One of his processors needs high levels of Vcore to make 4GHz possible, well in excess of 1.50V, and refuses to POST with Bclk ratios set higher than 200, regardless of VTT/Core voltages. The other two (3837A)are better than mine for IMC VTT scaling and can also handle 6GB triple channel memory at 2000+MHz with a little persuasion. Something I found impossible on my 3838A processor with 3GB of memory let alone 6GB. Also, both of his processors allow for 3.8GHz operation at stock or below stock core voltages with VTT near 1.15V. Both processors allow clock speeds to reach about 4.3GHz on 1.45V of VCore, but VTT required is near 1.425V on air cooling with a 2:8 memory ratio, change the memory ratio to 2:10 for DDR3-2000 and VTT requirements hit 1.50V, which also happens to be the maximum amount his processors will allow before throwing up a C1 code on POST.

he just reiterating his experience
but gary 920's had no issues.

thats what eva been trying to tell..
well just confirmed my 920 runs uncore 4000 without a fuss at 1.5v memtech hci stable 5000 percent ram at 800mhz
hopefully plugging this gt's would yield the same at 2000mhz.

for r2e 4000 uncore bclk 200
u need to find the right voltage for ioh/ich also..
no idea why but had to do this for mine.

[ChinStrap]

not to ask a nub question here, would these work on ... say... 790i?

[neo mike]

They should work in any ddr3 board, not guaranteed, but i want a set of these for my 790i striker 2.

[tripgood]

Just received and installed 3x2 GT kit on BloodRage. Tcl set to 7 in bios BUT it reads 8 in memset and cpuz. XMP disabled and set timings manually. Running 1.66v dram, 200 bclk, 20x, 20x, 10x for 2005 Mhz. vtt 1.46. Memory timings 7-8-7-20-1t 72 Trfc. Displays as 8-8-7-20-1t-72. My GTR's will do that on this board. Any ideas?

[Gautam]

Latest version of CPU-Z?

[tripgood]

Yes. And Everest, Memset and cputweaker. Foxconn bios are deficient in other bios mem timing areas so this is no different I guess. Still testing.

I have a slightly better i920 now, does not clock as high as my week 38s but I can run VTT up to 1.58 now without a problem. Not that I ever want VTT that high but this CPU will do it and will run 6GB at CAS7 2000 without a problem now. I have the Corsair 6GB 2000 kit at 2050 7-8-7-20 1T with 1.65V and VTT at 1.51V on a 20x206 setting, 24/7 stable. Drop CPU multi to 19x and watch the voltages come down....

Also, Andre was running VTT around 1.69V for his results, not good, not good at all on these CPUs....

High memory clock need high VTT, especially DDR3 2200+ CL7. I know you know that. Should I need to show up VTT 1.4V DDR3 2000 CL7 1.53V memtest 1000% for you.

Yeah I knew you folks said each cpu has differing cpu vtt handling but didn't realise how different it can be until i started testing my 2nd twin i7 920 3836A756 batch cpu.. if this thread post http://www.xtremesystems.org/forums/...9&postcount=37 doesn't illustrate the difference that can occur between cpus I don't know what will

All on TRUE120 air with DFI UT X58-T3EH8 1/23 beta bios

i7 920 3836A756 #1

• max memtest86+ bootable bclk = 224 requiring 1.58-1.60v CPU VTT
• max super pi 32m bclk = 222bclk (without IOH/ICH voltage tweaks) & 228bclk (with IOH/ICH voltage tweaks) requiring 1.60-1.61v CPU VTT
• max CPUZ Validation = 230bclk requiring 1.60-1.63v CPU VTT

i7 920 3836A756 #2

• max memtest86+ bootable bclk = 229bclk requiring 1.40-1.48v CPU VTT
• max super pi 32m bclk = 227bclk (without IOH/ICH voltage tweaks) & ???bclk (with IOH/ICH voltage tweaks TBD) requiring 1.48-1.50v CPU VTT
• max CPUZ Validation = 231bclk requiring 1.50v CPU VTT

no need Andre just show me super pi 32m at those clocks with CPU VTT 1.4v and 1.53v vdimm will be enough to prove your point

But yeah everyone knows higher mem clocks = more CPU VTT needed

[dinos22]

it's good to see i wasnt the only one scratching my head regaring this weird memory controller differences in chips....definitely interesting findings with you and Gary

But yeah everyone knows higher mem clocks = more CPU VTT needed

dont forget NB speeds
the higher it goes the more vdimm/vtt needed heh.....
