UnOfficial Asus Rampage II Extreme Thread

[CryptiK]

Drop multi to 17 or 19x, lower ram to a very easy speed, experiment with PCI-E freq from 100 - 115MHz, try slow mode once you hit the QPI limit. Dont go mental with Vtt, say 1.45v max if you are just playing around with your 24/7 gear. I got ~240 out of my R2E using that plan.

[xpower]

thanks for quick post.
vcore works fine with 1.2V.droped multi to 12x and ram to easy speed 1354Mhz and bclk to 220. 1.4v vtt with no problem booting but above 220 it gets little tricky and doest wana boot.tried slow mode aswell 222 but no luck.you think is the ram that is limited here? is corsair tripple ch 1333mhz 1.5v rated.any other sitting to try?

[zsamz_]

i had 2 rexIIs 1 was good for 229 n one was good to 224 so ...

[xpower]

221 so far.trying 225 but.........................................

[CryptiK]

Can be CPU or chipset limitation, ideally need a couple of boards to try it on. Do you really need 220+ or are you just experimenting?

[xpower]

my hobby is to clock bclk or FSB more than cpu clock.
220 booting fine but not stable in win.here what i am trying:
12x220
ram with less speed possible
trying diff volts

[xpower]

ok for some reason mem cant run 2:6 divider, getting "uncorrectible hardware error". but 2:8 works fine with default timings.
can this be mem problem ????

you gotta raise pci-e to 104-111

did that with no help.............

the board has a qpi voltage droop @ load
if you memory needs qpi juice ...
best memory on the rexII is elpida bbse i was able to do around 1800mhz 6-8-6-24

[xpower]

wana try different bios. can i put the original bios on one bios chip and new one on second chip.
procedure please....................

use the jumper
read the book

[xpower]

then what is "Bios boot priority" settings in bios?????????????

[zsamz_]

then what is "Bios boot priority" settings in bios?????????????

makes you switch from bios1 to bios2
a jumper needs to be enabled for that
or select by jumper

geez man read the damn book

[xpower]

flush bios fine but still not stable at 220 bclk.
124 bccode and some time "uncorrectible hardware error". that code is related to less or more qpi volts.or vcore. tries all settings but no luck..

you @ the limit of your board or your cpu

i got a great cpu n it maxed out @ 229x21 on rexII
on e760 i was stable 238x21

[xpower]

thanks zsamz. look like is the cpu. at 215 bclock works with min volts of vtt,ioh,dram and all other for 12X215.going to see how much vcore this cpu need for 20X200.

[xpower]

why qpi need 1.45v (bios set) for only 220 bclk. is IMC of cpu that required more volts?
or mem?
just wana distinguish.

bump ioh to 1.2 n 1.55 might help

qpi volts is related to ram if you run it slow no need for more than 1.3v unless the ram is crap

when you started your linx run you noticed the droop on qpi volts?

yep qpi volts drops.

[xpower]

bios 1504 sets qpi volts higher then other bios when is set to auto.qpi also drops on idle.LLC is on auto.

My contribution.

4.4 HT-ON 24/7 use

Notes:
Linx needs more v-core voltage than Occt to be fully stable.
Occt needs more Qpi/Dram/Vtt voltage Than Linx to be fully stable
If you can pass these stability tests on same voltages then you should pass all other stability tests.

Linx 20 passes


Occt(Linpack) 1 Hour


Intel Burn test 20 passes

[xpower]

how much bclk can u run on your board without slow mode with low multi?

[xpower]

any idea why mem looses 1Gb when trying to 1800mhz. its corsair rated 1333mhz running triple ch.

cpuz showing wrong info of 3GB, but bios and linx and other prog shows 2GB WTH..........

[xpower]
