SandyBridge 2D madness - let's tweak for the best 1m, 32m, pifast and wprime!

Hey Jody, looking good mate

Try a GBT board with 21,33 multi and see how it does. It could also be a CPU IMC not wanting to play as well rather than the board unless you've tried a few chips


add maxmem to the mix Brian that will go into 35 easy without any real tuning or special attention to OS

na, this is the first chip i have had. i definitely want to try a GB board, i think one is on the way.

i can run 2133 all day on everything but 32M. here is 6-7-6 pifast @ 1090MHz with the CPU clocks maxed to what the chip can do...



but 32M freezes the instant it is started. here is the best i managed with a quick attempt. prolly another 5 tenths or so in it with copy wazza changes and sub timings, but the chip is at a wall...

doesnt vtt help at all mate

i found the only way to run my hypers with 2133 ratio is to have a sweetspot with VTT on both UD5 and UD7 with same volts 1.24v, 1.22v is almost there, and 1.26 doesnt like it

that's quite a lot vccsa if you ask me - I am having similar issues with my hypers.
0.95V vccsa - 1.15V vccsa will boot 2133 with my hyper but freezes on 32m instantly. does your setup gives instant freezes on 32m initial below let's say 1.15V vccsa?

PS: stop calling it vtt - you confuse me every time

[dinos22]

in jeeegabyte world its still QPI/VTT


yes it scales, if i donthave these volts i cannot boot at all lol

VCCIO should be qpi/vtt/IMC voltage...

VCCSA is system agent

or maybe i'm wrong (still don't touched the biatch )

Good to hear that Gigabyte still call it QPI/VTT

[dinos22]

i thought he meant VTT hahah

system agent doesnt do

hahahahaha, looks like every chip is different, without putting system agent on 0.975 I cannot boot at 2133 CL8 at all. Also to be stable VTT has to be around 1.18-1.20 on my UD7.

interesting about that with the hypers. was able to play with it today for the first time and made no adjustments on the MIVE voltage wise and they were happy as could be at 2133 7-7-6-20 @1.69v....:/

I'm looking for a pair of ram which can do DDR 2200 CL6, maybe I'll give it a try.

Hi guys,

32M Update :

https://picasaweb.google.com/1119497...75125178057330

2sec less with MNH-E hypers, but I got to work again on that efficiency to make it sub 6 since I can't tightening timings more, vdimm is already 1,86v

Bye
