Intel 4.5GHz & 5GHz LinX Stable Club

[R37ribution]

Nice work zoson... that almost qualifies as a suicide run with that vcore lol.

Yesterday I wondered if my IMC and RAM were still ok, so I ran memtest for 7 hours overnight - no faults - and I ran LinX at stock for 2 hours this morning - also no faults, and the most insanely stable list of GFlops I've ever seen (63.4 GFlops every pass )

I've since been trying for hours to improve on my usual 83-84 GFlops at 4.5GHz HT and no matter what I do my rig just won't co-operate, even when I have control over all the variables. My memory subtimings are exactly the same every boot, and I've set tRL to help mitigate further inconsistencies.

Despite my efforts, the run that gave me 82 GFlops yesterday (standard boot, no tweaks) is giving me 58 GFlops with the exact same voltages and memory timings, right down to tRL being set to 58,59,60. I really don't understand what has changed that lost me nearly 25 GFlops, but the inconsistencies are really annoying me now seeing that others (Cryptik and McDown to name two) seem to get 86-89 GFlops with ease, and I simply cannot get to 85... Perhaps this 980X just has a sucky IMC...

180x25 for 4500MHz
CPU 1.4125v
QPI 1.35v
IOH 1.22v
RAM 1.65v

First off your RTL is way to high for an uncore of 3600 and memory @ 1800 (with CL @ 7, if CL was @ 8 these settings would be fine) - channel A should be some where around 54-55 and then add 1-2 for each add'l channel. Also your tRAS at 24 with 7-8-7 timings seems high too, unless this is what your RAM is rated at. try something like 20-22. A LOT of things can affect your gflops, including CPU PLL, memory timings, not enough vcore/vtt. Its pretty crazy, but getting your timings correct will help a lot. I'm not even part of this club yet, but I'm almost stable at 225x17. Once I get that dialed in I'll try for a 230bclk and then up the multiplier on my 3520.
