eva2000 Posted August 29, 2009 Share Posted August 29, 2009 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.

eva2000 Posted August 29, 2009 Author Share Posted August 29, 2009 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.

PCCstudent Posted September 1, 2009 Share Posted September 1, 2009 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 Posted September 1, 2009 Share Posted September 1, 2009 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. Link to comment Share on other sites More sharing options...

lutanica Posted December 15, 2010 Share Posted December 15, 2010 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... Link to comment Share on other sites More sharing options...
trackrat Posted December 15, 2010 Share Posted December 15, 2010 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?

Try it with a single module and see what you get. You may simply have a weak IMC. Link to comment Share on other sites More sharing options...

Just asking. Overclocking is a hobby not a destination. :laughing: Well mate. It was kind of a joke. I hate not knowing. I'm a person who must learn and know. 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. 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.
