@mac1as > 5Ghz is hard to achive and stable for 24/7. few things.try to up ur pcie frequency a little.LLC disable.read a few pages back for more tweaks.
and keep us update with ur oc :)

My bad, oops. that post was for another forum.

Anywayz, I want to add more RAM to my current OC in sig but relaxed to 4.2 @ 200*21 and keep DDR1600 @ 6-7-6-18. I can get another old set but how well will this mobo do on a 6 sticks config? What will I need to adjust or will i need to loosen timings as well?

This question might be silly but... Is it possible to use the bottom PCIe slot for a dual-slot-cooler gpu?

The idea I had, when buying this motherboard, was the get 2 GTX 580's and put those in the thirst and third PCIe slots, with a passive cooled 8400 and a soundcard in between those videocards. This would allow for better cooling and gives the use of the PCI slot.

But when I tried inserting a gtx 580 in the bottom / third PCIe slot I couldn't, because the connectors for the on / off switch etc. were blocking it. Could I just bend those, or is there some other solution so I could fit my gpu in there?

I guess it should be possible, else the option of running triple SLI wouldn't even be possible at all.

Testing a new CPU. It's hot here but I think its got potential, runs at least 10*C cooler than my 920 at any given voltage/speed.

4.20GHz @ 1.230v | 3.65GHz uncore @ 1.230v | DDR3-1625MHz 7-7-7-21 @ 1.495v

thanks for sharing. i think it can pass 5ghz mark without much hassle. it needs more cooling though. :thumbsup:

Nice low vcore clocks Cryptic! :up:

What cooling and ambient temps?

Thanks guys. Cooling is EK HF, Feser x-changer 480 with 4 Scythe S-Flex F's on ~1000rpm, EK Res 250, MCP655 on 3. GTX295 also in the loop.

I'm doing more testing tonight, had stupid bios issues with 1903 I was on, then more with 1914, so I'm back on 1504 which seems ok so far. Had cold boot instability (BSOD when entering windows with previously stable settings etc). Had my 920 in for over 1 year, it's fun getting to know a new CPU.

Without dodgy BIOS getting in the way, managed to do a little better tonight. Love this CPU, low VID but also not so hot. My low VID 920 only required 1.112v @ 4GHz to hit these temps :rolleyes:

This was at 1.263v mostly, but dropped to 1.257v from time to time.

4.3GHz @ 1.263v | 3710 MHz uncore @ 1.263v | DDR3-1780 MHz 8-8-8-24

I have a Core I7 975EE, always if i set BCLK to 200 i can't POST. If i set the QPI Speed Link to "SLOW MODE" (on my Rampage Extreme II) i can POST. I'm always at 24x QPI multiplier and i can post with BCLK from 160... but if i increase it... then crash... Why?, how can i get 200 BCLK and x18 on my QPI Speed Link?... it always set at x24

what am i doing wrong?

whts yours system spec etc

whats intel Xeon cpus highest cores for x58 rather?

Thank you for your attention.

My System Specs:

ASUS RAMPAGE II EXTREME
CORE I7 975 EE
6GB DDR3 1333
Cooler Cogage TRUE extreme
2 x ASUS 5970
PSU - Tagan Pipe Rock 1300W
Cage - Antec Nine Hundred Two

I can't set 200 bclk only if my QPI Speed Link it's set at "SLOW MODE"... what am i doing worng?...

I can POST only with BCLK 160...

whts your volts settings, u may need more juice. all the hardware are not the same. some boards need slow mode for boot. whats your board rev.

Hi xpower, thank you very much for your assitance. I don't like very high voltages because i'm on air cooling. I only can boot with "SLOW MODE" with 200 bclk and "air voltages" (nothing more tan 1,35 on VCore or QPI/DRAM), my board's revision is REV2 and BIOS 1914.

I think BCLK 200 on a 975 it's a very aggressive overclock for air cooling (if need more voltage than 1,35s). I give up that BCLK frequency because the QPI Frequency on a Core I7 975 Extreme Edition is a x24 and requires very good cooling system for very high voltages.

I can reach 4.212Mhz with HT ON below 80º in the hottest core using BCLK 156 x 27 and QPI Speed 3744 (7488MT/s) with 1,30QPI/DRAM and 1,28vCore (and i can reach 160 for BCLK without problems to boot).

What do you think about these speeds and temperatures?, they are good to go for using two Radeons 5970s?, Are good settings for gaming?

thanks for your help.

From what I think you are describing, it sounds like QPI speed is what is limiting you. These boards don't like going over 8000MT/s QPI. There are 3 QPI speed settings and slow mode - try setting it to the lowest speed (not slow mode). That should allow you to go up to 220 BLCK or so before you reach 8000 MT/s.

QPI speed and voltages and temperatures... I'm on air with a poor air cooling...

But i think it's not only QPI because (don't know why) if i pass from a BCLK at160Mhz i can't POST or boot... it's like the QPI-Multiplier it's doing nothing... always set at 24x... and "LCD Post" said "LOCKED".

I think BCLK 200 on a 975 it's a very aggressive overclock for air cooling (if need more voltage than 1,35s). I give up that BCLK frequency because the QPI Frequency on a Core I7 975 Extreme Edition is a x24 and requires very good cooling system for very high voltages.

I can reach 4.212Mhz with HT ON below 80º in the hottest core using BCLK 156 x 27 and QPI Speed 3744 (7488MT/s) with 1,30QPI/DRAM and 1,28vCore (and i can reach 160 for BCLK without problems to boot).

What do you think about these speeds and temperatures?, they are good to go for using two Radeons 5970s?, Are good settings for gaming?

The QPI multiplier is not denoted as '24x' in the bios, and its not permanently stuck on 24x either. When you choose one of the 4 QPI speed choices this sets the QPI multiplier accordingly. If you have the QPI speed set to what equates to 24x, it will reach 8000MT/s at 166 BLCK. If you run lower Vtt, this may not be quite reachable, it is on my CPU's/board but my CPU's have excellent IMC's and my board does 240 BCLK, however it still will not post at over 8000MT/s. 200 BCLK isn't aggressive for a 975 IMO, many decent C0's did 220+ BCLK.

What is your uncore speed at when you can't boot? Keep this under 3800 MHz or so, unless you want to run higher Vtt. What you can set this too depends on how good the IMC is and how much Vtt you are comfortable running. At 1.30 Vtt, you probably wont get it stable much over 3600MHz.

Also keep in mind there's quite a bit of difference between what you set in BIOS and real voltage, eg: set 1.32500v BIOS for Vtt and I get 1.250v load. If you are at 1.30 Vtt BIOS, you are probably around 1.23 Vtt real.

80*C is hotter than I like my CPU's to run, but I'm on water, for air and a fairly high voltage, most people seem to think 80*C is acceptable for stress testing apps (real world apps wont push it that hard). Your speed of around 4.2GHz is fine, just optimize your uncore and ram speed/timings and you have a quick system.

You will probably need more Vtt, but other than that it should be fine, however mixing different ram kits isn't recommended. 12GB of the same ram will work as long as your CPU IMC is happy, so as I said increased Vtt will almost certainly be required for stability at the same speed/timings as your 6GB.

It's fine to use it, so long as your case allows a dual slot card to be positioned there. You wont get 16x 16x 16x though as this board does not have an nf200 chip

My uncore speed is or AUTO or 2 x ram speed --> with RAM at 1604 my UCLK is at 3208 if it's at 1280 my uclk it's 2560.

My max QPI/DRAM voltage to get temperatures below 80º must be 1,35... if i use more voltage i'll get very bad temps (i have proobed with a max voltage of 1,47 and it's very "hot" for my system)... i'm on air!

If i set my QPI Frequency at "SLOW MODE" i can POST with BCLK at 200 any other QPI Frequencies with that BCLK can't post...

I can set ANY QPI Frequency with BCLK160 (max 3850Mhz/7699MTs) but can't boot or post if i set more BCLK than 160... what am i doing wrong?

Sorry for my english and lot of thanks for your help... i'm very confused with this...

Ok, try the following, I think perhaps there's something being overlooked here as the limiting factor. So essentially you cannot post at over 160 BCLK without slow mode - something's definitely weird here.


Try this. Set this all manually in BIOS:

Multiplier: 21
BCLK: 165
Uncore: 3300 MHz
QPI Data Link Rate: 5955 MT/s
Ram: DDR3-1650 MHz
Ram timings: 9-9-9-24 rest on auto

Vcore: 1.35v
QPI/DRAM (Vtt): 1.30v
Dram: 1.65v

Can you post?

Ok, i'll try it when i arrive home... but, one question before... why all system goes correctly when i'm at 160-166 getting speeds like 4.000 or 4.200mhzs?

thank you veru much for your help

I'm not sure I understand your question. You stated before that your issue was that you could not POST at over 160 BCLK. From what you just said it sounds like you can POST over 160 BCLK but only with CPU speeds of 4-4.2 GHz. I just need a clear description of what is going on here.

Ok, i did the test with your values:

"Multiplier: 21
BCLK: 165
Uncore: 3300 MHz
QPI Data Link Rate: 5955 MT/s
Ram: DDR3-1650 MHz
Ram timings: 9-9-9-24 rest on auto

Vcore: 1.35v
QPI/DRAM (Vtt): 1.30v
Dram: 1.65v"

and i can't post... I don't understand why, if i go over 160 in BCLK with a QPI Frequency fixed to "SLOW MODE" i can't post...

For clarify, I thought I had a problem with the QPI Frequency wich seemed not to change the multiplier (despite i've changed in BIOS)... but thanks to your help, i discovered that the BCLK over 160s may be the "issue"... i don't understand why i can't post with 200 BCLK.

If i use 160/156 x 27 (regardless my QPI Frequency), i can reach 4.200Mhz or more speed without problems (or using multiplier 133 x 32 for example). All my system is stable with those values, good gaming, temperatures below 80º on hottest core with PRIME 95, etc...

So i have 3 questions to be resolved...

1) My "dilemma" is to use 200 or 160 in BCLK...
2) My "question" is why i can't set 200 in my BCLK if i don't change my QPI Frequency to "SLOW MODE"...
3) and my "problem", is there something damaged in my hardware?, should i worry? or if i can reach 4.200Mhz with 150-160 BCLK i have enough power to move my 5970s

Sorry for make a post so long, sincerely, i appreciate your help because i'm tired of looking for answers about... :confused:

thank you again for your help, awesome thread and great forum

connector somethin is deffinatelly wrong

worst board i ever had did 214blk .
funny it was the rampage III:rofl:
even my old rexII gene did 215
reaseat cpu and chek pins

Do you have done this with an EE (975)?... if something was wrong i couldn't play nothing on my system... or getting good scores in Vantage, 3DMark2011, etc...

Should be LoadLineCalibration Enabled / Disabled ??

What I see when I enable it then my vdroop is not noticable during stress [LinX] in CPU-Z , unfortunately in PC-Probe vcore rises from 1.41v to 1.48v . Then... should I believe pcprobe or cpu-z ?? ;/

Probe.
My vcore rises in cpu-z when enabled.

Well I picked up a R3E and EK-FB R3E, so I'll be moving over to that :)

i left it on auto and never see any noticable diffrence.
@ cryptik why u leaving us :). good luck.

Just time for a change, had this setup running for ~18 months, and been on water almost 12 months. R3E and EK full cover block allows me to go full WC with a newer board. It gets pretty warm here in summer and the mobo PWM gets hot with a CPU at 4.3GHz + and the R3E's digi PWM is nice, as is the EK block!

The R2E is still a great 24/7 board, never had any issues with mine - it will be going into the gf's pc with my gem 920 replacing the X48 REX and Q9650.

i really hope you get a good rexIII
i regrett the day i sold my rexII n bought a rexIII
my rexII was good for 229 blk and my rexIII was good for 114blk lol

114 BCLK? Think you meant 214 BLCK no?

In any case max BCLK doesn't matter to me, I'm running a W3570 ;) This will be a 24/7 work/gaming system anyway.

yes lol 214

the rexIII made me wish i kept my 975 lol

Sad that u leave the RIIX club but happy for your new gear... :)

Tells us how it goes... Pics with block installed also...

Yes well there were some reports of it playing nice with GT's but not bloomfields, so I'll see how I go, I'm not anticipating any problems. The R2E has been a great workhorse, and did 240 BCLK 2D as well :)

Will post back once the new stuff arrives, and for sure I'll provide some hardware pr0n pics :D

I'll still be in the R2E club though, it will be moving into my 2nd pc the gf uses. She had a terrible old PC so I sold it and made a good one for her, first with my P5Q-D and 8400, then my X48 REX + Q9650 and now the R2E and my gem 920, so she gets an upgrade when I do. It's my spousal hardware management plan and it works flawlessly I must say :)

Lucky gf... :D

Ok R3E pr0n pics as promised :D

Some pics of getting it ready to install:

Prepping the board:

This kind of shocked me. There appeared to be grass and debris on the stock thermal pad! It's also a hack job in terms of pad cutting precision. Nice QC asus.

Looking good man, cool times ahead :)

its a 8 power design to cpu. good luck with RP3 + Heineken ::)

how good does the i7 970 run on this board ?

Are there any problems I should be aware of?

Thanks

beautifull board cryptic
but to me it was 1 of the worst boards i ever had

mine was good for 216blck (R3E) but hopefully you get one with a good IOH.

Thanks for the pics Cryptik... :)

hi again guys im back here with some willing to go above the 4.2GHZ , Im specting to see 4.4ghz at least for 24/7 setup .

Right now im running 4.2 GHZ llc off , HT disabled with the following settings

tested a some LinX runs went and got a continuous rate of 61 GFLOPS at 181Secs each . no variations at least the runs i give.

My settings

Multi X21
BCLOCK 200
QPIV 1,35
CPU BIOS - 1,3750
CPU PLL 1,82
VRAM 1,65
ALL REF to +0MV
IOH 1,35V
IOH PCI V 1,51
ICH 1,14
ICH 1,51 1,51


i know most of you here are ppl that know very well how to overclock , and since that i would like to have some advices in order to reach higher clocks.

PD : also need some help with mem , since i always wanted to give them higher and better timings but i never understood how to. or how it worked.

*** one thing i forgot to mention is a very strange issue when i tried to downgrade Bios from 1802 to 1504 , i could do it with afudos by using a usb bootable but then when i started windows. i had only 4GB of ram , instead of 6GB that i currently have.

Then flashed back to 1914 and then memory came back. i believe this is nothing concerning a bent pin from the motherboard or nothing like that because it was the first time it happened without doing any changes to the mb so why this could happen?

need quick response please...... :)
trying to test bclk, what things to consider? with 12 multi and ram with low freq.
need your input guys

i test max blk @ 19x never bothered with lower
ram lower frequency helps too

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.

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?

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

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

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?

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

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 ????

did that with no help.............:mad:
mem cant run 2:6 divider, getting "uncorrectible hardware error". but 2:8 works fine with default timings.:shrug:
can this be mem problem ???? :rofl:

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

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 :rofl:

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

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:D

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.

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.

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

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

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..........

Seems that ASUS will be releasing 2002 bios for R2E in a few days with support of recently announced Core i7 980 (2002 is mentioned in CPU Support List for R2E).
Does anyone have it already?
Hope they updated Option ROMs at last.

Just downloaded it from there FTP site ;-)

Just checked. No, they didn't update option roms in 2002 bios (Intel Sata Raid, Marvell LAN, Jmicron Sata Raid). Unbelievable.

What did you expect? They routinely use ancient roms when other companies are on the latest. Lazy.

Yeah, but they released bios for R3E with updated Intel ROM, so I hoped that they do the same for R2E. But no. It seems that, according to Asus, this board is SO MUCH outdated, and of course, R2E owners will never buy the latest and greatest SSD - those old school people simply never heard about SSD.

Hey Guys. Long time reader, recent sign up :)

Finally started getting into stretching the 920's legs on the r2e to see what it can do and have now realised that the overvolt protection will kill me. I take it BIOS releases past 1914 ( what im on) havent happened to correct the issue??

Im fairly confident ive hit my bclock wall at 220 as it wont even boot windows at 221 with a decent qpi vtt of 1.45 ( 220 needs 1.35) so will sadly limit the top speed.

One other query i have with you owners/past owners : Is it better to run llc off or on? Ive always ran it on, but with the r2e adding the 0.03v odd extra, wonder whether i should be turning it off or not. Sorry if the answers are in this thread, im still reading through it :)

Cheers
Az

Hi and welcome. What overvolt protection are you referring to? I've run 1.60v load on the R2E with OCP disabled in BIOS and there was no issues.

220 BLCK is pretty normal for this board, unless you use slow mode for QPI data link rate, which allows you some headroom if your board and CPU can go higher with BCLK. I ran up to 240 BCLK or so on my 920 using slow mode.

There's no right answer for the LLC query - some run it on, others off. Technically from what I understand allowing the load line to droop with increased current draw is preferred as it prevents large overshoots when the cpu load drops, like when tests finish for example. There are people who have run it enabled since day one and haven't reported noticeable cpu damage clearly linked to it, so its up to you really. I ran it off, but then again I wasn't running mine at 4.5GHz 24/7 either.

llc off i needed less voltage to be stable

i was able to reach 229x21 blk fully stable
never bothered with slow mode
i found that bbse chips ran best cause of qpi voltage droop
psc should work as good

Thanks for the replies guys. As to overvolt protection, I meant how the turbo multi drops when the vcore gets up near 1.35 or more and drops back to X20 under load .. or is there an easy way to stop this happening? (vr override im talking about)

Might try slow mode and see if the bclock wall moves at all.

Edit : Answered myself after finally reading it. CPU Turbo Power Limit :)

Could you explain what is that 'Option Rom' and what about those 'latest' SSDs ?:/ What do they have in common ??

With LLC enabled my vcore during stress raise from 1.38 to 1.442v (as CPU-Z shows) Why so huge droop ??

My settings are : 207x21 , QPI 1.35 PLL1.82v , VDRAM 1.67v , IOH1.11v ,ICH 1.15v

What else I can not see in my BIOS option:

EPU II phase control - full phase

which is listed in this thread on first page in bios template settings.... ?? Why ??

My Bios is 1504


Thank you for help.

Anyone know how i should go about fitting a PCIe soundcard on this board? Got a Asus GTX 580 DirectCU II(takes up three slots), so the white PCIe x1 slot is covered, as well as the second blue PCIe x16 slot, can barely fit an "old" PCI soundcard in the 1 PCI slot. Got the black PCIe x1 slot ontop, but the heatsink is in the way for normal length PCIe soundcards i believe. But i got the third white PCIe x16 slot, though you can probably not put soundcard on that slot?

Any tips on the matter?


Edit: Looks like it should be possible, so am gonna give it a try once i buy a new soundcard.

I still have this board running my 920 at 4.2GHz. I have a quick question about it though. Is it okay to enable the intel virtualization while oc'ing? Will it cause any problems or make the oc unstable?

I don't know for sure, but i'll have it on at all times 'cause vmware likes this... ;)
Maybe try to disable it for your bench or record sessions, but for 24/7 use i like to have all functions available... ;)

Cheers!

no problem while overclocking yet its enable all the time............

Is it possible to go back to a older Bios?

Curious what BIOS others are using for a stable overclock with a Ci7920?

Thanks

My result in 3Dmark vantage.
HT enabled,bios 2002.

Hi,

Just downloaded the latest BIOS rev 2101 from the ASUS FTP site and works pretty solid ;-)

yep its been discussed in this thread on how to flash back bios.
just using 2101 and had no issue with overclocking :)

Hey gang,

I'm looking in to getting a SSD for my Rampage II and I've noticed that a few of you already have them set upped on your rigs.

My question is the board has SATA2 ports and the new SSD's comes with SATA3 out the box. Would the SSD not preform to it's max because it is connected to a SATA2 port?

My setup has been (for the most part) rock solid since day one. And would like to upgrade to SSD, just want to know if this great board can take it.

You comments and feedbacks welcome.

Maybe I don't understand your question right, but a SATA2 port is a SATA2 port and behaves as such, no matter if there is a SATA2 or a SATA3 device connected to it. This means that you could get full SATA2 speed out of your SATA3 SSD (if there isn't a firmeware bug in your particular SSD preventing this).

Allthough this isn't optimal. I suggest you get yourself a PCIe SATA3 controller AddOn card and hog your SATA3 SSD to that or (if you plan on using your R2E for a while longer), get yourself 2 SSDs (SATA2 or SATA3, whichever is cheaper) and put them in a RAID-0.

But please read some tests and then decide what SSD to get. Don't just get the cheapest SSD around. There are huge differences in every day performance. Trust me. A good starting point would be anandtech.com.

Btw: Intel is releasing TRIM support for RAID-0 SSD arrays in the next version of RST.

Cheers.

Hello guys.....It's been a while since I have posted in this thread. I have started having an issue with my Rampage II or my PSU. I am trying to figure out which one would be causing the problem. I have been losing usb devices whenever i put a large load on the system, gaming, prime95, etc. For example, I have usb powered external HDD's that stop working along with other devices when I start gaming. When I stop prime 95 or when I stop gaming the USB devices start working again. Usb devices that require less power still work fine though, like mice, keyboard, etc. I also noticed some strange fps drops while gaming in tri sli....Would this be a motherboard voltage regulation issue or psu issue?

@ Bringer
try with single card and see any thing sorted....................
