Ok I will show proof, but first things first:
I checked the reviews and 75MHz extra ram clocks with keeping the cpu equal only gains 630 marks and this is on a 6800gt too. 550MHz gains 3121 marks. Thus we can infer that the gains are 8.4 marks per MHz higher ram clock and 5.7 marks per cpu MHz. Thus if I get tccd and I am forced to run 280x9=2.52GHz vs. 290x9=2.61 but ram at 236 let me do the math: 90MHz cpu clocks is 513 marks while from 236 to 280 is 44MHz higher on the ram which is worth 370 marks. Thus I would lose 513 marks cause of lower cpu clocks but gain back 370 marks cause of higher ram clocks. Lets do the math what fsb with tccd id need to match 290x9 with my corsair value I got running async. each fsb gains 8.4 marks ramwise and 51.3 marks cpu wise for a total of ~60 marks. 513-370=143 marks so I would need 283fsb 1:1 to be 37 marks ahead of 290fsb async with ram at 236. 282 would be 23 marks behind. My odds of hitting 290fsb 1:1 is very small as proved here:

Charlie, a well known and respected member of XS hit 310 single channel but only 255 dual channel. Others have also gotten around what he got. a lucky few have hit 280-290 dual channel but the odds are very small. I would need 283+ dual channel just to be ahead of corsair value at 290x9 async since my winchester does just over 2.6GHz and the loss of cpu MHz costs you alot. There is a big price difference between my corsair value and TCCD for a slim chance of getting ahead and even if I do get ahead, my gpu is slower than a 6800gt so I will not gain as much as he did. The overall total is 630 marks going 200fsb to 275fsb and thats on a 6800gt. 8.4 marks per MHz on the ram, if I somehow get 290x9 on tccd, it will only be 44fsb or 370 marks on a fast gpu. on my gpu, its probably gonna be a little less, maybe 300 marks or so. When I am already well over 20k marks, I just dont care much about another 300 and if I did, I need only ~65 MHz more on the cpu to gain my 300 marks. 65MHz more is 2.5% boost in performance. Thus if I luck out and hit 290x9 with tccd, I will gain 2.5% overall performance in games and 3dmark. This small gain is most likley not even noticable in games and not even huge in benchmarks either. I would be better off spending my $ on a faster cpu or gpu before I buy tccd ram. Whew I hope I explained myself well and the logic for it
by the way I checked reviews like this:

max oc his ondie controller got him was 275 at ras-cas3 or 285 at ras-cas4(but 285 wasnt 100% stable either) This would make it a waste of $300 for tccd just to sidegrade. I could sell my winchester for $150 and buy more and keep the best one, reselling the others for a $20 loss and theres a good chance ill gain higher cpu clocks if the next winchester ocs better. However I am not going thru winchesters, just stated an example. another thing I could do is sell my softmodded 9500np for like $100 and add another $300 for an x800pro or 6800gt and ill come ahead. tccd and my 9500np isnt gonna be quite as fast as corsair value and a faster gpu, yet both cost the same! my funds are limited so I must choose the best path and right now I simply will wait for prices to drop, stuff to become faster.
