Nice memory :D

Last week I tested ten 2600K L044B693. They all were bad. One of them could boot 2c/2t 5600 under water, but had no stability. Under SS it worked at 55xxMHz only, 5600 was unreachable
Seems in ex-USSR(Ukraine, Russia) have no good 2500/2600K. :down:

Tested 16 pcs. of 3101A201s...pretty decent batch averaging 53Xs with SS

Even with small samples I ended up with (1) 5.50Ghz s/n A1181 - (1) 5.65Ghz s/n A1499 - (1) 5.75Ghz s/n A1983 4C/8T

The only similiarity I can think of those >55X cpus are s/n 1000ish and between 80~99 for the last two digits

Code:

cheers :) but don't worry, it's the vcore

1135mhz run vccio @ 0.88v set = 1.032v cpuz 1.56 (for B2)

need more efficiency!!! :confused:

Awesome job Nick, as always of course :) :up: So 2x2GB GTX2 performs similarly to 4x2GB PSC right?

obligitory 5ghz shot. im missing something somewhere. olive gave me .2

nice work mr b.

will u be trying 4 sticks?

Cheapseats thanks for sharing :) .....Always interesting in reading your posts,lots of quality informations within...

With proper PSC,6-10-7 would be doable and that would buy some effieciency :)

5ghz

i cant catch zeneffect lol

It's all about memory now Honda. For example, tighten that tRP from 7 to 6 and you'll get about half a second :) Work on your RAMs more :up:

oh..thanks for advice..i'll keep at it... the gskills that i got aren't friendly with tCL(7) ....so sad :(

i cant catch aristidis lol

looks like we can start a conga line :party:

sorry that run was kinda not tweaked ...

edit:

finalrun attached..gskills sucks with tCL(7)

can't quite catch the hypers ...

Haha yeah Aristidis's run is damn fast, he's a good SuperPi 32M bencher :D ;)
But your runs are great as well guys. I'll soon join you with some PSC and a 2500K @ 5GHz. 6m33sec is my goal :)
