Sequel of a Turtle RAM issue [1] I had on fam16h AM1I-A : a pair of [2] modules crawls as 1333MHz CL9 on A88XM-E (F2A85-M clone) with A10-6700. That's despite a really similar pair [3], just 1600MHz CL9 and in a SO-DIMM shape, runs on its' top 1600MHz CL9 speed at Lenovo G505S with A10-5750M which is also fam15h. I hoped this Turtle RAM problem is isolated to fam16h (thought that fam16h AGESA was a bit immature at its' time of release), but seems it affects fam15h also!
I tried making buildOpts.c of A88XM-E at [4] as similar as possible to a successful G505S, considering they are from the same fam15h family and hoping that my change [5] will force it running at least on 1600MHz - but didn't help. :( Consider installing those SO-DIMM modules with a SO-DIMM to DIMM adapter, but not sure it will change anything.
Why AGESA memory training is such a crap on fam15h desktop, while working fine on fam15h laptop? My clumsy hacking of AGESA wasn't successful on fam16h AM1I-A - but maybe because I was trying to do that at the wrong places! So I really need your advice, where exactly are the critical AGESA source code places I should hack to force that "overclocking" ?
Thank you very much in advance, wish you a Happy New Year ;-)
