Just as you can see below, my RAMs is working on 1684 for now and When I have pushed them 2000MHz, PC just hangs on a black screen at the BIOS boot so I understand they require a bit more voltage. But DRAM bus voltage is enough in my opinion. To What should I give more voltage and how much voltage should I give?

What's your RAM supposed to run at normally? If it's 1600MHz I don't think you're going to reach 2000MHz even overvolting.

You could try upping your uncore voltage as well. The Kingston 2000MHz kit I'm running sets the uncore voltage to 1.7v with the XMP-2000MHz profile.
 
sorry ! silly me! forgetten information. my rams absolutely supports 2000mhz

ASUS P6T SE X58 Socket
Intel Core i7 920 d0
Thermalright Ultra 120 eXtreme Rev C
TEAM Xtreem LV (3*2) 6GB 2000mhz 9-9-9-24-2T
Sapphire HD5870 GDDR5 1GB 256Bit
Seagate 1TB 7200RPM SATA-II 32MB NCQ
Thermaltake Toughpower 750W
 
Just because your RAM can do it doesn't mean your motherboard can do it. With that said I've never seen an X58 board that couldn't at least go past 1866MHz. On any board that would do it that I've worked with, all I've really ever needed to do was set the memory settings manually to match their exact specifications and that's it. Given the board you are using you should be able to do the same. However your board may not work the greatest with that RAM. You'd have to try some different 2000MHz RAM to know what the problem was for sure.
 
friend but asus specification says mobo supports 2000 even more?

or you simply recommend buy a different ram 1600mhz cl7 etc. ?

The motherboard supports 2000MHz RAM through overclocking. I've never seen an ASUS or any X58 motherboard that couldn't do 2000MHz or close to it, but still bear in mind that you are overclocking past the specifications of the X58 chipset when you do so. In regard to the memory, you should try different 2000MHz DDR3 memory if that's an option for you. If not, then you should probably up your voltage slightly and relax your timings. Bear in mind that 2000MHz should be the upper limit of memory which is rated at 2000MHz. You may not get exactly to 2000MHz with every combination of motherboard and that memory. Shoot for 1866MHz or something then work your way toward 2000MHz.
 
In order to get 2000 memory, you will need significantly more QPI/DRAM core voltage.

My chip needs 1.4375 QPI for 2000 speeds and I consider it to be a fairly good chip voltage wise.
 
I can do 2000MHz simply by setting the timings manually. As for voltages I don't have to do much. I leave QPI on "AUTO" then set the DRAM voltage to 1.65v. That's it on my machine.
 
Fair enough, If I leave shit on auto on my board it thinks way too hard and generally screws things up, usually by overvolting/undervolting or setting things too tight/loose. If I dial in settings to what is needed everything is rock stable.
 
Well just setting my RAM to those speeds like that while running the rest of my hardware at stock settings works fine. However, when overclocking on this thing damned near everything had to be set manually.
 
Gotcha. Haven't tried running the memory at 2000 with stock cpu speeds. I don't think this chip has seen stock speeds unless I'm installing Windows or flashing a BIOS :)

I figured since he is running a high bclk that he is probably trying to run 200 bclk/2000 memory but it is not stated in the OP...in that case a significant increase in QPI voltage may be necessary, much more so than auto :)
 
Another problem he may run into is dialing in 2000MHz memory speeds with his given BCLK and available memory dividers. I know with my current settings I can go to about 1866MHz or way over 2000MHz which I know my RAM won't do.
 
In your post, you stated:

"DRAM CAS# Latency - 9 DRAM Clock
DRAM RAS# to CAS# Delay - 9 DRAM Clock
DRAM RAS# PRE Time - 9 DRAM Clock
DRAM RAS# ACT Time - 24 DRAM Clock"

Not sure if it is going to be the same for your board, but my RAM likes to have the DRAM RAS# ACT Time set to 1 over what the first 3 add up to... so if it is set to 9,9,9, my board likes 28.

8,8,8 and it likes 25.

Below that it becomes unstable.

You may also need to mess with the other timings.
 
i gave 1.45voltage qpi dram voltage, 1.20 ioh voltage, 1.3 cpu voltage, 1.66v dram bus voltage and 1.82 cpu pll voltage but i could not run 2000mhz.

please advice :(
 
Yeah I can confirm issues with Corsair's DDR3 2000MHz memory kits. I had a module burn up on me. Corsiar made it right, which is what was important. Currently I've got 12GB of the stuff in my box and I haven't had issues since. However, it can be very finicky to get stable at certain speeds. Right now I'm running the stuff at 1866MHz speeds I believe and so far so good. Been that way for a couple of months now.
 
Yeah, don't run your QPI/VTT voltage that high unless you don't care about your chip.

What are you using to verify stability? Linx? Prime? IBT? OCCt?

Considering the XMP Profile automatically sets you Uncore voltage to 1.7V I don't think there's a ton to worry about. And one time isn't going to kill your chip flat out.
 
why dont you raise the multiplier to 20, drop the bclk to 200, and set the ram divider to 2:10 and see if that works?

because at the settings you are at right now, the next divider is 2:10, but it'll set your ram speed at 2110 mhz, which is over the specified speed

also, im a bit confused when you said you set them to 2000 mhz in your bios, does your bios let you set them manually, or are you using the dividers, because the last time i checked, my bios only allowed me to change memory speed based on the dividers
 
p6tse bios doesn't give option to change memory ratio(divider or whatever you say)

I can only change speed. like 1600, 1866, 2000 so on so on.

I tried blck 200 and 133 before. but It didn't work
even I tried to change All BIOS settings to default and only changed dram bus voltage and speed. but It didn't work.

xmp profile doesn't work.

I just took a look mainboard user guide. all 2000mhz memories requires 1.9v.

perhaps It is time to try 1.9v dram bus and 1.6v qpi.

That's the same thing. Those numbers should change as the bclk changes.

Unless the RAM packaging states it needs 1.9V then it shouldn't require that high.
 
according to your memory manufacturer, you shouldnt need to exceed 1.65v to get your memory up to 2000 mhz

http://www.teamgroup.com.tw/teamgroup/en/productDetail.php?pd_id=410&pl1_id=1&pl2_id=1

and from what i understand, the memory clock is directly related to the cpu clock (bclk and qpi) in this architecture, so are you sure that your cpu is fully stable and that none of the settings are making your memory run at speeds higher than 2000 mhz?

1.7 VOLTS? Are you fucking kidding me?!?

Everyone says 1.4V is the maximum safe uncore voltage... and here they are going 1.7V? ....

My 920 won't even run 2000mhz RAM at 1.4V uncore. It needs 1.525V in order to run the stuff stable.

seriously?

i got my memory running at about 1925 mhz with stock timings of 7-8-7-20 since overclocking to 4.2 ghz to reach 2000 mhz increases my cpu temps beyond my liking, and my uncore is 1.3v, and thats with a little extra overhead

so i think somethings wrong if your running it that high since 1.4v is the commonly accepted max

also, what are your temps reaching under load with linx?
 
Not sure if this will help, but I've also been working through the settings on my board trying to figure out how to get my RAM to run at 2000MHz. However I am using an i5 750, Asus P7H55D-M EVO and 8GB of Kingston HyperX PC-16000 CL8. In case you have something similar on your board I found the BIOS option "Xtreme Phase Full Power Mode" to be absolutely critical in getting all 8GB of my RAM to operate at full spec.

Xtreme Phase Full Power Mode can be 'auto' or 'enabled' - on my system it needs to be enabled full time, otherwise if I try to run the RAM at full spec it tends to blue screen while booting windows, and then 4GB gets disabled until the speed is reduced.
