Low timings with TCCD

post #1 of 11
Thread Starter 
how do some of these guys that are really overclocked run ddr500 and ddr600 with low timings and 1t on TCCD memory? my voltage is set at 2.85v max and from what i read, the max that TCCD really likes is 2.9v which my mobo overvolts to....

what are your timings? and do you have Corsair 3200XL? I believe that's the only DDR400 Corsair has that uses TCCD IC's

I run my OCZ platinum rev. 2 (TCCD) at DDR520 every day... 2.5-3-3-7. I can't run a 1T command rate... but that's cause of my mobo... it's unable to run 1T past a 240Mhz htt.

TCCD doesn't gives better performace as you increase vdimm. I get better Oc results with only 2.75vdimm and when I pump it up to 2.85, i get bad results. Currently, I'm running my ram at 270mhz (DDR 540) at 2.5-3-3-5 1T.

see, i was running up until yesterday 2.5-3-3-7 1t @ 260. then i decided i need more. but i'll try that lowering the voltage and see what it does. everyone else that i've talked to said RAISE RAISE RAISE.

and yes i have 3200xl. those little buggers put a big freakin dent in my wallet.

The guys you see running DDR600 2.5-4-4-7 or similar timings with 1T are with DFI Lanparty mobos or some other mobo that overclocks really well. Their voltages are the same as yours, as TCCD can't go above 2.9 volts without something negative happening. DDR600 isn't even the ceiling for some good TCCD, but you need a good mobo to get there.

I've seen people give TCCD over 3.0v (well actually, I've seen one person do this...) Apparently he said that it helped his OC. Although, it seems that this is an isolated case...my TCCD goes all the way to DDR640 on only 2.9v even though OCZ warranties their TCCD to 3.0v

In my experience, sometimes increasing vdimm will affect your Oc/benchmark negatively, sometimes its best to leave it stock

I agree 2.6-2.8v is right where you want to be with TCCD.
