UnOfficial Asus Rampage II Extreme Thread

[pcnazz]

Got lucky and scored an i7 975 x factory sealed ( 1/2 of retail price ) to pop in my RX2 mb . Should have it early next week . Anyone need a sweet overclock-able i7 920 DO for $225.00 delivered anywhere in USA let me know , original box and unused heatsink .

Hi guys I had a quick question for owners of this Mobo. Im just upgrading my system and kept my R2E as the MoBo. I'm wondering I have been running 3 X GTX 280's in TRI SLI. but Now I'm keeping one of them and running 2 GTX 480s.

On the manual of R2E it says that the top to PCIE slots (Blue) are PCIE 1 and 2 and the Black one on the bottom is 3rd. But other mobos and threads state that the Middle one is usually the 3rd PCIE Slot.

How would I install the cards? Would I put the 2 GTX 480's on the top two and the GTX 280 (physx card) on the bottom? or the GTX 280 in the middle?

Hi every one.
other day i were discussing with a AMD user.he said the base FSB on previous generation was 333.but on this R2E board base FSB or (bus speed) is 133.actualy his agument was that the FSB degraded in new generation.what is the logic all of this.can any one explain.
thanks.

[madmax999]

There is no more FSB on X58 chipset. It's called baseclock now and it doesn't have any connection with FSB.
This AMD user is telling you bs...

hey guys
iv been reading this thread alot (thx for the info) since i got my R2E... AMAZING board! i got 250 bclk out of it this weekend for some 2D benching. iv noticed that when i increase the PCI-e frequency the grapics performace degrades heavily! is there a way to counter that or is the only way to run at a lower frequency(PCI-e)? a friend of mine ran his at 103 (on a ASUS P6T Version 2 + i7-950) and then it was fine. where is the sweet spot and what should you avoid?

Specs:
i7-920
R2E rev2.01g (i think thats the right rev)
Team Xtreem 3*2gb 2000mhz
HIS 5870 1gb
Corsair TX-950

[madmax999]

I just can't believe that you managed to achieve 250MHz BCLK with R2E. Can you post some proof, cpu-z validation for example?

any advice about the PCI-e and 3D? i see most ppl 3D with a 920 at about 4,5-4,7ghz

Wow 250 BCLK, insane for an R2E. Rev 13 chipset though, the Rev 12's which most of us have are terrible by comparison.

I have no issues with 116 MHz PCI-E and 3D, but I use an nvidia card, perhaps its your ATI that doesn't play nice.

[seraphs]

all thanks to Vivi and R3D :P
il try get a nvidia card and see if its that but i doubt it. will keep you guys posted

[Moonunit]

Nice one Seraphs, keep up the good work, maybe I should put mine under dice or LN2, hehe

[seraphs]

LN2 is a waste on these chips in my opinion. i got that on dice, its the boards limit (i think, hit a wall twice but with the right settings i got past it) im gona try get a 950 or Vivi's 975 for some 3D goodness

What can i say... Impressive.
But rev 12 R2E's suck

I had GTX280 and could run PCI-E till 130MHz without any problems(on my ex-Bloodrage with hardmod). And with ATI cards I had random problems with PCI-E above 110MHz.

I also noticed that I could run CPU on higher clocks under LN2 with nVidia cards compared to ATI cards. The difference was ~100MHz.

Hi,
i'm very newbie on overclock world. I have a very simple answer:

is it normal that i have to put my I7 975's vCore to 1,4x (1,42 to 1,48) to get 4,2Ghz on my Rampage II Extreme ?.

if i put less voltage i can't reach 4,2Ghz.

[CryptiK]

Is it a C0 or D0? For a C0 that's normal, for a D0 that is higher than most require.

[madmax999]

AFAIK, there are only D0 975's.
1.4V is way too much. Try to raise VTT voltage to 1.3V and then try to lower vcore voltage.

Thx for the answer madmax and Cryptik.

Automatically, on "Crazy 4,20!", Rampage sets the vCore to that value with BCLK at 156 x 27 and vCore 1.48, rest auto, memory at 1250mhz.

I try this but it doesn't start with 1,32 or 1,35:

CPU Ratio --> 21
BCLK --> 200
Dram Frecuencia --> 1203
UCLK --> 2406
QPI/Dram --> 1,32v or 1,35
CPU PLL Voltaje --> 1,90v
IOH Voltaje --> 1,24v
Load-Line Calibracion pon Enabled
CPU Diferential --> 800mv or auto
CPU Spread spectrum --> Disabled
PCIE spread Spectrum --> Disabled

CPU Configuration:
C1E Support pon Disabled
Intel speedstep pon Disabled

I don't know how to get best vCores...

I see on firts posts of that thread, that there are some people are using 1,4 for start to reach 4,0:

jasonelmore - 1,43v:
http://www.xtremesystems.org/forums/...95&postcount=3

"So i have you starting out at 1.43. If this does'nt work, then try 1.48. "

SonoFader - 1,47v:

and many more...


Are you sure is it doesn't normal?.

How can i get 200 BCLK and 4,2 with less vCore with a 975 EE?

Hello XS

I recently updated my bios(1504 from 1306) and I think I have done something
because my vcore is unstable as hell for some reason. Idle it is around 1.244v
and load it reaches up to 1.290v.

I have it set to 1.2500v in bios and I know mycpu needs around 1.24v to
be able to run 4ghz. What is wrong with my settings? My settings are:

What is wrong I got it stable at 1.256v before always and that

if I disable LLC or have it enabled it the vecore still goes up and down.

cpu and gfx is watercooled and I have pretty much all cpu settings
enabled except Intel Speedstep tech should I disable something?.
My computer passes 20 times in linX as it is now but I dont like to
have a jumpy vcore as it ruins for me if I want to OC the cpu to 4.2ghz.
Also my QPIv is quite high but it needs to be over 1.35v with this cpu otherwise it becomes unstable.

Sorry, i'm very newbie on OC (sorry for my english too) but i think the reason is this:

http://icrontic.com/apps/nehalem-calc/

Input your BCLK and CPU-Multiplier, the result is an excess of QPI (7.708) this causes instability.

Try putting BIOS settings in PHP tags like I just did for you, makes it heaps less arduous to read your specs & browse the thread.

Sounds like load line calibration is boosting your vcore under load, this is unfortunately a feature of Asus LLC. Personally I would like it to simply make idle/load vcore the same but for some reason Asus make it increase under load. Just disable it, then your vcore will droop under load as per intel specs.

Wow 250 BCLK, insane for an R2E. Rev 13 chipset though, the Rev 12's which most of us have are terrible by comparison.

I have no issues with 116 MHz PCI-E and 3D, but I use an nvidia card, perhaps its your ATI that doesn't play nice.

LOL, didn't notice about revisions though....

Mine is rev 13 but now i have some problem of trying to get it to run past 215 bclk...i'm trying to eek out every last mhz available using 1.45 vcore on air but it seems even with most settings for voltages are yellow, its still a no go...

So u see my settings I have put the QPIv to 1.35v now what settings do u think I need to have to be able to run
4200mhz so far it seems everything I tried is unstable and the cpu runs 4000mhz fine @ 1.25v. What mutiplier
and bclk should I try? also what is optimal for my ram speeds?

At first i was annoyned about the overvoltage under load, however i have to agree with Asus on this.

It's best to overvolt under load to keep your oc stable, on the other hand when idle, it's better to have lower temps.

[zsamz_]

i use to use llc on 1.38v idle 1.4 load
now its off and 1.36 idle 1.34 droop @ 4.4

Look at this interesting review about Extreme Editions and multiplier use:
http://www.tomshardware.com/reviews/...d0,2386-6.html it will clarify you a lot (sorry for my english). And for OC try this --> http://icrontic.com/apps/nehalem-calc/

excessive BCLK = excessive Tensíon and excessive Voltage on the Cores.
