*HOT* | Corsair DOMINATOR GT | 6GB (3x2GB) | DDR3-2000 7-8-7-20 @ 1.65V | *HOT*

[AndreYang]

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

[Gautam]

lol...careful whenever you ask Andre to prove something.

[cstkl1]

hmm theres one thing i want to add about uncore
on cooling .. theres something to do with idle/load difference or something else

this was the result at 200bclk ram at 1600mhz ioh at 1.24v ich at 1.24v HT OFF

intel stock
3.8ghz 1.182v memtest hci stable 5000% 1.6v set for uncore 4000

true+CM 90cfm
4ghz 1.3v memtest hci stable 5000% 1.58v set for uncore 4000

coolifreezone elite
4.2ghz 1.352 memtech hci stable 5000% 1.48-1.5v for uncore 4000

same proc.
still dont get it why. multi?? unknown temp factor??

thermal paste application exactly the same
polish with as5 and smoothen with tx2 on proc and heatsink

just wanted to share

cstkl1, better cooled cpu will also help better memory clocks but could be the balance needed between vcore, cpu vtt and vdimm - need more folks to investigate heh

very nice Andre, my cpu ain't as good can't handle DDR3-2008Mhz 7-8-7-20 1T at 1.4v CPU VTT

Can you run memory on this settings with voltage less then 1.64?

[eva2000]

Can you run memory on this settings with voltage less then 1.64?

nope but haven't played with other voltages and well it all depends on cpu mem controller

[bingo13]

Those are really good results. Can you do that with an i7 920? The MSR tables could be setup differently depending on the memory multiplier, so the read/write leveling, clock skew delay/advances, and a whole host of other items that are setup dynamically at POST are subject to change.

How does it do with an actual load on it? I can pass 32m all day at those VTT/VCore rates on the Corsair, but once you start encoding a 1080P clip with Cyberlink Power Director 7, converting a 24MP image in Photoshop CS4, modifying a AVCHD clip in Adobe Premiere Pro CS4, or playing Crysis, it is BSOD time. Hence, the higher rates to ensure stability in actual application testing, not a program barely stressing one core and less than 50% of the memory.

In the end it really does not matter what program, CPU model, or settings are used. The quality of the IMC is going to determine just how well the memory performs at each gate. I could use a crappy 965XE or 920 we have here and claim Corsair's latest GT 2000 kit is unable to hit 2000, much less 1600 at rated specifications. Would it be fair, no, but it is the truth in this case. The truth if you consider this particular 920 will not do more 3.6GHz stable, even at 1.50 VCore and memory refuses to go higher than 1520, regardless of VDimm/VTT/Ratio.

I just think people need to realize this up front when we are discussing results with memory products on the i7 platform, otherwise, there are going to be some very upset customers when their latest $600 memory kit will not do what is advertised or they push VTT so high that they are arguing with Intel for RMA approval.

hehehe....I don't have i7 920 for testing.

In fact, my 965 IMC is not bad at all. I just prove I can use VTT 1.4V for sure. 1.69V VTT is only for 2200+ CL7 testing.

That's a nice summary of the current state of Intel hardware. And you are right about impending consumer wrath when they begin to understand. My issue with the GT kit not being able to run cas 7 @2000Mhz on my BloodRage isn't because of a substandard imc or any ram problem. I tried 4 different chips, two of which are much better than average (3841Axxx). Maybe Corsair will have to include an asterisk with their adds that specify which boards are capable of running at those timings assuming you have a decent chip. Oh well, my DFI doesn't suffer with this kit. If only I could change the color...

[cstkl1]

hahah after shifting to a new casing the rv01
my nb temp shot up to 63c
not qpi 4000 is not stable

so gskill tech was right.. need good cooling on nb.

[cstkl1]

ah confirmed its the nb temp..

opened the case nb temp dropped to 55
and now memtest hci pass 1000%

before nb at 63 failed at 30% and bsod

[cstkl1]

did further testing with another r2e

failure happens at 60C. for r2e

[eva2000]

yeah heat could be a factor when stressed with high CPU VTT

DFI System Temp = PWM temp
DFI Chipset Temp = NB temp

blend

[cstkl1]

eva here is one more funny thing

hx1000 vs op1000 ( not the e version..the previous long EPS)
corsair dominator 1600 C8
dram set 1.65 both in bios
Stable Clocks
op1000 7-8-7-20 1T
hx1000 8-8-8-24
probe reports the same 1.648v

weird aint it.
but then that op1000 had killed a few rams before including a am3 900 C3 1N.
hmmm

testing now with da1200 and pcp750

[eva2000]

weird i'm using HX1000 right now with my DFI UT X58-T3EH8

I'll be setting up my DFI JR X58-T3H6 with OP1200 though

[cstkl1]

test bro so far da1200 also is doing 1600 7-8-7-20 1N
probe reading is the same.

i was like wth

[bingo13]

hehehe....I don't have i7 920 for testing.

Actually, your IMC is great.

[cstkl1]

for r2e found y the 60C temp
actually think is a one off case
the reason is the dram/qpi voltage card
took off the logo and put some heatsinks on it.
now np 4000 uncore stable again but with 7-8-7-20 1T tRFC 60

[cstkl1]

ok no sign of corsair shop updating the status of the stock or any email informing its available
safe to sleep. :P ..

[nelsoncp21]

I heard a rumor that the barbs for the optional watercooling blocks are made of aluminum. Is this correct and if so can they be easily swapped out?

No this is not correct. They are nickel plated brass.

[nelsoncp21]

awesome. I thought it would be odd. thanks.

There are no "hidden costs". During checkout, there will be sales tax or VAT added to your total, plus shipping costs. Your credit card company takes it from there and applies currency exchange rate.

I just received my hot ramm, they got even hotter when the ups delivery person said i had to pay a additional 106,90 euros tax
I had no idea about this, since i had payed tax for it allready which had been added to the price of my ramm...
my total expences makes a total of 660 euros = 917 dollars..........


first time i ever ordered something from abroad, it would have been nice tho if there was information about extra costs for people outside the US..
maybe i can get some tax back, have to check....

[pinto]

same here already send PM to Bachus and corsair website!
