Corsair Dominator GT + Asus P6T6 WS Revolution

[eva2000]

First time use of Corsair Dominator GT 2000C7 kit on Asus P6T6 WS Revolution. Not bad for quick dial in settings with auto set tRFC value. Fast 1M & 32M Super Pi efficiency though!

With 6GB Corsair Dominator GT 2000 7-8-7-20 kit of memory I never got to try looser 8-9-8-x timings much with DFI UT X58-T3EH8. So now on Asus P6T6 WS Revolution, will try 8-9-8-22 2T timings to see how much further I can push memory.

Used TurboV to push mem to DDR3-2320Mhz but couldn't save the CPUZ Validation files heh. Will try again for next session :)

 

QPI/DRAM (Uncore = CPU VTT) = 1.650v

Took a side by side screenshot of my 12x mem multi DDR3-2184Mhz 7-8-7-20 1T 32M run versus my 10x mem multi higher cpu clocked DDR3-2118Mhz 7-8-7-20 1T 32M run to see what cputweaker reported for my subtimings. See if any subtiming settings are a factor.

 

http://fileshosts.com/intel/Asus/P6T6_WS_Revolution/results/w3540_3845b010/corsair/2000c7_gt/321/22x/12mem/182_1092_78720_1n_12_155_116_16_11_16_182_ctrlrefc048/10mem_1059mhz_vs_12mem_1092mhz_2.png

 

DDR3-2184Mhz (12x mem) vs DDR3-2118Mhz (10x mem)

 

• QPI/DRAM volts = 1.55v vs 1.6375v due to lower bclk needed on 12x mem config
  
• tRFC = 110 vs 88 could be a factor ?
  
• tRRD = 7 vs 7 both same
  
• tREFI = 955 vs 849
  
• tFAW = 37 vs 33
  
• tRTL A channel = 56 vs 57
  
• tWTP = 27 vs 26
  
• tRTP = 7 vs 6
  
• Write to Read (same rank) = 20 vs 19
  

 

Going to play with subtimings and see :)

 

Update: Dropped cpu multiplier to 19x and using 10x memory multiplier, will try to reproduce similar looser subtimings as used in my DDR3-2184Mhz 7-8-7-20 1T run with 12x memory multiplier. I managed to get as far as Super Pi 32M stable @DDR3-2188Mhz 7-8-7-20 1T at 1.84v vdimm :)

 

Manually set following subtiming values in bios:

• tRFC = 110
  
• tFAW = 37
  
• Back to Back CAS# Delay = 4 (tightened to try and offset loosened tRFC value)
  
• Write to Read (same rank) = 20
  

 

Super Pi 32M passed at:

• DDR3-2158Mhz 7-8-7-20 1T at 1.72v
  
• DDR3-2167Mhz 7-8-7-20 1T at 1.78v

I posted and asked Wired about OC advice and recieved the"we can't provide help or information concerning overclocking,you are free to visit other Forums for this information". You have twice as many posts as me but 160 total posts shouldn't make you special.No offense,just wondering why I recieved the "Wired" brush off.

[Wired]

Eva posting his OC info has NOTHING to do with Corsair not being able to give out OC info. I've never said NON-Corsair people couldn't talk about OCing. Hell, if that were the case there wouldn't even BE an Enthusiast section.

I don't see any request for help here. He's just posting his results.

Yeah i'm not asking for oc'ing advice. I'm just sharing my overclocking results with everyone which is well within the confines of the rules on the forums :)

Does something by the name "overclocking illuminati elite" exist around here? A group who does magic and voila they get these Dominator GT 2000Mhz sticks running at 2000mhz with so low vQPI and vDIMM???! I mean there are many many people busting their *** to get these stable even at 1600mhz.

 

Guys, please help me (who is literally going insane) here. First I have 2000mhz CL7 then I thought something was wrong with them and I bought the newer 2000mhz CL8 (CMT6GX3M3A2000C8 ) but still not stable. I mean I have tried EVERYTHING ! Setting sub-timings manually accordingly to CPU-tweaker's SPD, loosening the timings. setting vQPI from 1.5 to 1.6, (by the way with bclk 200), changing CPU (920 and 930 with pretty good batch actually - low vcore), changing motherboard (P6T6 WS Revolution). I mean what in satan's name do you do guys to get it stable?? Or that's one of your illuminati rules - not revealing the spells ?!!

 

Is there anything special in the sub-timings that is the pain in the *** here or what?

 

I use prime95 to test for the stability. In my OC, I set the CPU multiplier very low below stock. So, only OCing the RAM with BCLK. my unstability in prime95 has a weird pattern. I use FFTs from 768 - 4096. right? When the vQPI is around 1.5, all FFTs from 2048 - 4096 are stable but FFTs from 768 - 2048 is unstable and onle ONE thread stops (not more). As I up the vQPI a notch, the unstability goes one FFT-level up. Then keeps going till I hit vQPI 1.61 or something. (first time I thought that I got stable there) and then I ran the FFTs from 768 - 2048 and then BOOOM. The unstability had gone in circle and back to the begining.

 

So, what the hell is that? I have vIOH set to 1.24v and CPU PLL set to 1.8v. Please show me a way here or I'm gonna have to jump off a cliff...

[trackrat]

So you plan to jump off a cliff because you are unable to OC your RAM to 2000 MHz.? :confused: Do you know there are starving , homeless people in the world? Just asking.

 

Overclocking is a hobby not a destination. :laughing:

Not every CPU/IMC is capable of hitting 2000. Try it with a single module and see what you get. You may simply have a weak IMC.

Well mate. It was kind of a joke. I hate not knowing. I'm a person who must learn and know.

weak IMC on both chips? I have tried this thing with 2 different CPUs u know. Could my PSU be the problem? Giving too little on the +3.3V rail (cause I can tell that V3.3+ is actually V3.2+ in my case) or something like that. Because I have this issue with both the C8 kit and C7 kit.
