yeah its basically the same

hey Sam i was thinking about what you said in the past about the hand picked stuff is nothing like retail and unmatchable, i have some thoughts on that,

in the past i agree with you, but on this platform things arnt the same for me, my 2 best sticks that i previously did 2800 7-11-7 with are no longer my best sticks, in fact they are just some retail kit i didn't even realize was PSC and just ripped out of a litecoin mining rig,

i tested a bunch of PSC this weekend, some mine, some owned by a bunch of different Australian guys, all the retail stuff that used to be 'average' on Z77 is now clocking the best on air, i haven't tried LN2 on many kits yet, but the sticks that i used to consider my gems are now getting beaten by a 2000c7 flare kit that i didn't give much respect to in the past

flare couldnt run 2600 on air in z77, now doing 2666 8-12-8-27 1T, trfc 82, twcl 6, same secondaries/tertiarys i want to use on LN2 minus trfc @ 1.91v

sorry for being OT

Also on XS.

Alex-ro - 7:21:540 - 40x100 - 1300 MHz - 8-12-8-28-84-1 - Asus Maximus 6 Extreme - GSkill 2200mhz Pi 4x2GB/PSC - 1.9v - Air CPU/Mem

PSC on air have not so great efficiency for me at least,going to check the best set of these two(which can do cas 7 twcl 7 2600 on air 32M :D) on dice.

@youngpro very interesting, is this related to the haswell imc or do you think it is issue of the board you tested on? I skip Haswell, at least until now, so I cannot test my psc, one of these is in fact also Flare kit that already does 2600 8-11-8-28 on Z77

I've yet to see any huge difference between ivy and haswell at clocking memory(psc,sams,bbse) except they work little better on haswell.I've binned a dozen of psc kits on haswell and ivy,correlations are the same,better kits on ivy work better on haswell(m5e + m6e both cases used).

i dont think its IMC related, i swapped in and out chips and i didnt see the mhz go up or down, i think in the 2600-2700 range IMCs are very similar for PSC/BBSE, but i only tested limited samples

I lol'd a little when this finished

Hope Jake sees this. ;)

all air everything

7:20.922 - 2400 C7 - Hypers

if you are having issues with cpu-z reading wrong voltage open the cpuz.ini and try Sensor=0

hey guys,

james and I did a lot of testing on the weekend with PSCs and ran into some problems with cold and could not tighten to 7-10-7 or 6-10-6

it was bios related! I confirmed it in testing last night and today and we're making a new benching bios that will sort this out. My PSCs arent too great so i couldnt really do a great deal more than 1300 cas6 and 1333 cas7 but a few guys do have some gems which should be cranking it pretty hard now. will update it when it's ready

tuned the OS a little... maybe I gain a little on BBSE ;)

nobody else wants to join the hyper fun?

None of mine run 8 8 8 2400 :) been working on some interesting stuff. Looking pretty fast @ 2600 c8 will post soon

looking forward to 2600 c8

Wow cool! I will try my kits, 4x2 dom gt 1600 cl6. At least one of them could run 2133 7-7-6 on SB @ 1.80 vdimm but it was slooow for the clocks back then.

edit: So I tried hypers too. My kits can't make much more than ~2250 MHz at any timings. Quick Pifast comparison between my fully tweaked BBSE @ 1300 8-11-7 1.85 vdimm and "just getting started" Hyper MGH-E at 1098 7-7-6-24 1.92 vdimm:

BBSE

Hyper
http://hwbot.org/submission/2395832_...770k_11.69_sec

Pretty neat huh? :)

Max pifast = 1130 MHz 7-7-6-23 1T trfc 68 with 1.96 vdimm. For 32m I will need cold on them.

still working, not bad at 2600 :)

So glad to see some Hypers again! :rocker:

not bad at all... have you played with your waza sizes? i went against convention last night and found another .2 :)

Not yer. Time cut was strictly voltages :)

@ZenEffect: do same settings pass 32M at 5GHz? :)

don't have an air 5ghz chip to be honest. I can maybe next weekend when I start freezing things.

*edit*

or maybe tonight, checked tracking and my ek plates are supposed to be in today so I might play with a little dice, ln2 next weekend :)

@Splave

sa, ioa and iod? I noticed if they aren't set "right" things start slowing down. the auto rules are pretty good though.

ill have some 4ghz times soon, maybe i wont challenge andre but should have some alright times

been playing with a couple boards and just getting some time to properly pay on z87/memory, pre-computex was a little too full on

Been through several bios's, all my timings both good & bad & spent 1/2 a day yesterday playing with voltages & ended up with exactly the same score as my previous 2 attempts. After seeing Alex's great run I was hell bent on not posting until I could at least break the sub 6 min mark but I just cant make it so this will have to do as my best.

Nice result man,if you lower trfc and some tertiary a little you'll reach your goal easily :)

There's got to be something I'm not getting but that really is the best I can do. Might be me, my chip the board who knows but its real tough with my Samsung's on the 2800 divider. I have a hard time adjusting secondary's. Lower trfc is slower for me & although I have run trrd 4 & trtp 4 it don't like it so I ended up setting 3 which must put the board into panic so it sets the lowest its happy with to boot. I been right through my timings & just cant get my samsungs to play nice on the 2800 divider.
