I am sure the memory has to keep be able to keep up but I am seriously thinking the chipset has more of an impact unless someone can tell me otherwise. The reason I ask is this. After many, many lost days due to issues with prime failing I copied the Anandtech article settings quite closely and achieved some success, however, they are using settings that just don't agree well with me at all. At 445 x 7 I can run prime for up to 10 hours as long as sub timings and TRD Phase adjust settings are left at auto. If I try and change any of these, even slightly, I will fail prime, even if it still isn't as aggressive as others have set them with more voltage to boot. I am trying to narrow down the problem so I can solve it but I am wondering if I am wasting time assuming it is on particular part of my setup when it could be something else completely different. Raising volts does squat and I am really hating tuning the GTL's to their ultra sensitivity when being fooled with. My TFRC is 42 default, most have theirs down to 30 to gain some bandwidth without problems yet I can't even do 40 without prime failing. The TRD Phase adjust settings were adjusted just like the article suggested with all set to auto except one on channel two to allow 'breathing space' for the chipset yet it still fails prime. I would really like to get more from my system though it seems 445 is about max without having to go crazy on the volts which makes my already hot temps even hotter. Cpu is at 1.325 in bios, VTT at 1.60 and chipset at 1.61. My GTL's are 115/114/117. If anyone has an idea what is going on please sort a brother out before I punch this thing and give up. I am loving this setup but its not a smooth ride at all for me. Rest of parts are as sig lists. Sorry for being long.
For me the Read delay phase adjusts just help you tweak out your setup, theres no need to play with them (leave them on auto) until you have everything else where you want it.

The Read delay phase adjusts help you run in between performance levels, For example with the early BIOS's my rigs ram run with Read delay phase adjusts all on auto Orthos stable @ 1140mhz performance level 7 using the 333/800 divider @ 475 x 8. It would not run if you alter any of the read delay phases. Now if I then changed the ram divider to 266/667 which boosted my ram speed to 1190mhz I found I lost some performance as the 266/667 divider by default runs performance level 6. What I then did was enabled some or all of the Read delay phases to try to run in between PL6 & 7.

I think it was the 1005 or 1019 BETA BIOS that finally let me run all the read delay phases enabled. I later found out my RAM would run PL6 @ 1190mhz with these BIOS's too.

I have played for days with GTL tuning & come to the conclusion (& I am going to be slammed for it) that GTL's although they have a profound effect on stability are an un necessary waste of time. It may just be my setup but I seriously doubt it. If you just switch your "GTL+ Buffers Strength" from default strong to weak then leave the "GTL Ref Voltage Control" disabled you like me will probably be able to make 450-480 x 8 Orthos stable.

GTL tweaking is however vital particularly for the NB to stability when benching/running on the edge.

I would also up the vcore a touch just to be on the safe side & loose 2GB of ram until you get it stable.

P.S for those of you that disagree please say so & why but don't all shoot at once.
