TRD was not my doing really, i have been going on about straps and performance tweaking with Intel hinting but never telling
, performance level (my friend Roger
) was the key to getting the ball rolling for TRD to finally start showing its face...FCG has pushed the envelope much further though even coming out with little calculations showing where things "should" work and where things just won't. I still think we need to map out TRD Vs FSB adding Vmch maybe into the mix so that we can see whats damn fast and what is slow... this has to be done per board though as its obvious from Asus 965 changing tRD at 401fsb and GBT changing at 435FSB different boards by Auto are going to give quite different petrformance.
It also shows what a mess memory reviews were, there is no way you could compare dimms tested on different boards with different bios files altering tRd at different points...easy way of making X brand dimms look good on Y brand board me thinks if engineers and PR work together.
You can also see this could be a way for X memory company to work with bios engineers to add code to spd that tells the board to increase tRD at a given FSB to allow "their' dimms to do the super high clocks and V brand does not due to the rules of TRD and FSB.
Not saying this has happened but it makes you start thinking as it would be dead easy.
tRFC, yes this is my doing, I pushed some reviewer friends to help me get Asus to sort the issue out as reviewers seem to have more influence then engineers (specially me, i can't even get boards to test with unless i beg for days, sometimes weeks)
I latched onto a product OCZ developed a few months ago (4GB memory kit) and started pushing it around 1000MHZ+, what I noted though was tRFC had a massive impact on how the IC's clocked up,lucky for me I was using DFI and Abit P35 boards with fully open tRFC in steps of 1, so I did not have any issues pushing OCZ to produce what you see as Reaper X EB and 8000 Reaper X, the issue was when I finally started testing on Asus boards (P35 and x38)
and found the boards severely tRFC limited, so much so 1000MHZ rated dimms were hitting 950 and stopping and in some cases not even allowing a boot.
Lucky for us Asus are fixing it, and the bios I have even though some parts are broken does allow tRFC to scale and I was testing at 1066 with dimms stuck at 940 with the previous bios build.
Overall "us engineers" in the background are really trying to get you guys what you need and trying to explain how things should work, we may not pour LN2 and have massive clocks to brag about but we at least contribute to how boards work and give the tools for those who play super cooling something to play with.
