Live MB OC Report :: ASUS Rampage Extreme

[Ghostleader]

this is a crazy board
400fsb 1:1 1600 CL7 1T tRD 5!!!

Yes it´s.

How much volt do you have to push through that NB to reach tRD with CAS7?

[cstkl1]

Yes it´s.

How much volt do you have to push through that NB to reach tRD with CAS7?

hehehe
vtt = 1.12v
nb = 1.259v

gtl 0 = +40
the rest auto
( if tested all the gtl's with a vmm and can confirm with u guys this
gtl 0/2 = 0.635
gtl 1/3 = 0.667
how to test

easy run linpack with fsb 400 and ram just at 800 everything auto with ure rated voltage for that ghz...
and nb is 0.64...confirmed. over and over again.

the thing is set strap to 200
and reduce the clock twister to light

and MAKE SURE U ENABLE THe dram dynamic thingy to enabled...

and 1600 CL7 tRD 5 is possible for 4x1gb
the benchy just now 1N is actually not stable and 2n is just marginal
what i found more stability is

set channel A to pull enabled at trd 6 with 2N.. so basically a 5/6 trd
and u will get around 10400 with 4gb kit and the best of all around 48.6-49.0 for latency...

still find 4 sticks on this board is a bit unstable because of dimm A1 and B1
IBT proves this over and over again and also theres 4 test i like to do that shows stability before i run linpack

all must be run in diagnostic mode in priority 10 for orthos and virtual mem disabled. with a 64 bit system.
Test 1 .
Run Orthos, Go to Blend and then to Custom.
Change from 15 minutes to 1 minute... This will show how unstable ure GTL is very quickly.
run all interations twice so roughly one hour 30 minutes or so.

Test 2.
Run Orthos Go to Blend and then to Custom
Change min FFT to 4096...
this will show unstable ure gtl/nb/mem is .
run for atleast two runs so roughly 33 minutes or so

Test 3.
Run Orthos Go to Blen and then Custom
Change Max FFT to 8
this will show how ure CPU vcore to GTL and NB is unstable...
run for atleast two runs so roughly 30 minutes or so.

Test 4
Of course fav HSI Memtest for atleast 100% for 4gb roughly 1 hour

if u can pass the above.. linpack is guaranteed and ure gaming is fine and dandy and u will pass prime95 12 hours all the interations

so far on this board with 4 dimms i cant pass any of this test...
not a really happy camper here

2 dimms yes .. but 4 nope...
which is y linpack 50-100 runs.. aint happening any time soon.

OCCT.. such a lousy test... even gaming crysis warhead from begin to finish is a better test of stability

also theres a trick to this board for rams...
u can gain better nb voltages with good ram timings and trd loads with straps and ai clock twister

example strap 400 with ai clock twister stronger at fsb 400 CL7 trd 7
or strap 266 ai clock twister moderate at fsb 400 CL7 tRD 6
or strap 200 ai clock twister light at fsb 400 CL7 trD 5
keep trying with the dram dynamic this enabled or disable.. DONT LEAVE IT ON AUTO..

[Ozzfest05]

OCCT.. such a lousy test... even gaming crysis warhead from begin to finish is a better test of stability

What? every time I run orthos or prime 95 I can run it for like 2 hours before it fail the same configuration fails in the first 10 minutes in OCCT I switched over for that reason, please dont put negative comments about a good program So far its the best ive used along with lin pack, If my system passes 3 hours of mixed testing in OCCT it will never crash during games all my Overclocks have been tested never had a program I ran loops of Crysis Benchmark program on highest settings for an hour and OCCT Failed in 7 minutes.

[cheapseats]

hehehe.....nb = 1.259v.....

Really amazing vNB with 4x1GB - with same clock but CL6 , I'm up to 1.53V (set) for just 2x1GB and 2T (and not 32M stable yet )

Very interesting post - many thanks for sharing

Here's my 2T-only OCZ3P18002GK on 0801 (windows boot from BIOS)

400 FSB/ 1:2 / CL6 / 2N / tRD5 / CT stronger / 266strap / Read + Write enabled / vNB 1.53V set / vDIMM 2.05V set



more voltage - vNB 1.59V set / vDIMM 2.15V set

hey no offense personally
just that i find occt is really doubtful... was actually comparing to that four test... sorry about the crysis comment..but when it comes to 4x1gb clocking occt doesnt stress enough on the rams and gtl.. personal opinion..

especially when it fails very often one of that 4 test i use... before linpack..
been clocking that way for a long time and always found with that 4 can usually pass anything...

oh yeah i dont aim for gaming stable.. i want super stable...
and this board is damn hard.....for 4x1gb...

[cstkl1]

hmm has anybody gotten a proper reading for the nb gtl..
i keep getting mix result..
sometimes 0.64 and sometimes 0.667

No problem I only use 2x1 sticks im getting better clocks slowly just received the board a week ago or so 1960mhz is real nice though, I use OCCT then Prime 95 for overnight test sometimes but mostly Linpack OCCT and I use PI, I do ram overclocks but mostly focus on cpu the 4.4ghz and 1960mhz ram is good for right now and real low voltages are being used but I dont know how much more I can squeeze out of this air set up.

My version of stable is passing 1 hour OCCT Ram and Mix tests Linpack 32m SPI and Running for a week at the clocks if no crashes occur then I cosider it stable

[cheapseats]

not planning to keep with 4 sticks - just seeing what I could get with OCZ + Transcend as 4x1GB (XP 32bit only though ).

Micron (OCZ?) and Samsung (Trans?) not great together - no CL7 with all four sticks in, and nothing higher than 800mhz on any divider.

Memtest86+ 4 x pass before this Windows run, so 'stable' as far as tested. Everest Read and Latency are hopeless, but 32M time seems reasonable.


vNB 1.56V set / vDIMM 1.8V set / CT Strong

[aln688]

Could some people who have time, please post what make and model of RAM modules you are using, and also what stable OC speed you've managed to get out of it. I have Kingston HyperX 1625 modules which I've read can get up to 1720MHz, not the highest but at CL7 still respectable. I'm asking incase I need to change my modules to 1800MHz versions incase I want to OC higher than my RAM will allow.

Thanks.

[aln688]

3oh6, Rob2k,

Question, if you look at the Rampage Extreme as fitted in a case, there is an Asus heatsink at the top right of the board, it's the typical gray slotted fins, with the spring screws through the back of the board. Have either of you replaced this heatsink with copper as well? I think I'll have enough Enzotech copper heatsinks to cover whatever is under that heatsink.

[3oh6]

i haven't changed it and to be honest, a heat sink there isn't really necessary. hell, even the MOSFETs for the NB are optional i would imagine. these components are designed to run high temps and most boards don't have them sinked. most of the cooling solutions on motherboards these days is nothing more than branding.

[rob2k]

Hi Aln688, the same goes for me as with 3oh6 above - i've left this H/S stock.

As for memory see pt no in my sig and post #1506 for my 24/7 stable settings. The Doms are working at 1880FSB (940 memory bus) which is not a huge overclock as I feel that my quad is the limiting factor here at 470 but the timings are tight at 7-7-7-20 CR T1 and common performance level 06 which converts to decent read bandwidth over 12k.

Ghostleader is having some good results with the same sticks combined his E8600 - see post #1512.

The Doms are the 3rd set of DIMS I have tried after having OCZ2000Mhz and G.Skill 1600Mhz. If you have not yet bought your memory then I would recommend 1800 or 2000 rated sticks so that the memory can keep up with your overclocks on the 1/2 divider.

[aln688]

Hi Aln688, the same goes for me as with 3oh6 above - i've left this H/S stock.

Alright, thanks. I'm going to remove that heatsink just to see what's under it. If I'm going to rip out the entire Asus heatsink assembly, everything goes. I'll try to use some of the Enzotech copper heatsinks on whatever is under the stock.

The Doms are the 3rd set of DIMS I have tried after having OCZ2000Mhz and G.Skill 1600Mhz. If you have not yet bought your memory then I would recommend 1800 or 2000 rated sticks so that the memory can keep up with your overclocks on the 1/2 divider.

You mentioned 1/2 divider, considering my RAM is 1625, if to start with I had a 406 FSB, then could I keep my memory linked to the FSB? This would mean 406 * 4 = 1624? Is this the same as 1:1 divider?

My aim is for a 425 FSB, which will give me a 3.6GHz on the CPU and 1700MHz on the RAM. From what I've read about my Kingston HyperX modules, the RAM can OC to around 1720MHz but still retaining CL7.

Is what I'm suggesting doable?

This is my first Intel and DDR3 system after many years of AMD and DDR2 so anyone please correct me if I'm wrong. The FSB freq is quad pumped so 4x the bus speed where the divider is the FSB to DRAM ratio so half of the effective FSB freq with the 1:2 divider. Then with DDR memory (DDR=Double Data Rate) the memory speed is multiplied by 2 for it's effective frequency which then equals the FSB freq (so yes 1:1 there). By using another divider the memory can be ran slower - and more recently faster (asynchronously). Usually running components synchronously yields better performance. Think of the divider as the fraction of the FSB frequency but then double that result for the memory frequency. Hope i've not made a hash of that and i'm not teaching you how to suck eggs (as the saying goes!). What you have in mind sounds fine and perfectly achievable after binning the HPA.

The 2x1Gb configuration in the white sockets seems to be the most clockable on this board.

I'm not exactly clear on a few points, and anyone can jump in to answer if they want. Is it true that to overclock the RAM, it's best just to have 2 x 2GB modules? Or can I have 4 x 2GB modules? Ideally I'd like 8GB of RAM. I got the idea that to overclock RAM, it's not viable to have 8GB in there.

Currently I have already bought the Kingston HyperX DDR3 1625 modules, 2 x 2GB of them. From reading reviews they can overclock to 1720 at least, one review site pegged them at 1810 but at CL9. I'm considering returning them to buy the Corsair DDR3 1800 modules the same as what you have.

But, if I buy the Corsair 1800 modules and end up running them at 1700 all the time, would I be as well just to keep the Kingston's? As said, I want to overclock the RAM for a 425 FSB, but I'd also like 8GB at the same time.

[Ozzfest05]

its best to have 1 512 or 2x 1 gig, 2x2 gigs doesnt overclock as well and most of all never fill 4 slots


with only 1 512 ive seen 2600mhz ddr3

[ci2kla]

Just bought an RE to play~ mind if I join in this discussion to contribute
Yesterday got some test. Settings as below (briefly)
FSB: 540
Multiplier: 8
divider: 200/667

Voltages:
CPU: 1.35v
CPU VTT: 1.19v
CPU PLL: 1.55v
vDIMM: 2v @ 7-6-5-18
vNB: 1.51v
GTLs:
CPU 0/2: +50mv
CPU 1/3: +10mv
NB: +40mv
1.5v SB: 1.55v

Others on auto

With this strap I was able to boot at tRD = 8 and Pass dual PI 32M
With 1.41v vNB I got BSOD right before I saw the desktop
With 333/1066 divider the machine was bootable but BSOD when loading Windows using tRD = 8

What's interesting is, compare with the anaxxtech's review (Rampage Formula)
It has a formula about the calculation if the machine will be able to POST or not using a certain tRD.
While 333/1066 divider's value is bigger then 200/667 in terms of theory we should be able to boot up and load to windows without a problem using the same tRD value.
The problem is, with 333/1066 divider tRD @ 8 is completely unstable while 200/667 can boot up and pass dual 32M, even memset to tRD = 7 for a memory benchmark (possible to pass PI as well, haven't tried)
Any suggestions and comments on that?

And, I have a problem on overclocking my CPU to 4.5Ghz, will post the problem later. Still looking for assisstance
(Sorry for my bad english)

EDIT: The scene as below
FSB 500 Multi 9 4500Mhz
vCore: 1.3875v 1.392v Load LLC Enabled
With this setting I can pass OCCT for 2 hrs mixed test
But in ORTHOS I wasn't able to Pass even 1 minute and always get the same error: Final Result Mismatch
It does not make a single difference by rising the vCore to 1.425v. However it do pass dueal PI 32M...that's confusing...please help

Sounds great, Rob2k. One thing I do know, DDR2 is 2 x the FSB (in otherwords DDR2 fetches data twice per clock cycle), where as DDR3 is 4 x the FSB (...or four fetches per clock cycle). I learned this after reading lots of reviews on RAM modules and the overclocking section of the articles.

I understand the FSB divider now, it's merely a way to disconnect the FSB from the speed of the RAM. I suspect using anything except a 1:1 divider will very slightly impact performance of the system as a whole. When you say "synchronously", I think you mean 1:1 ratio with the FSB to RAM.

Great, thanks for explaining! I'm glad my plan sounds alright, my Enzotech heatsinks arrived today, going to start removing the heatpipe assembly and install the Enzotech's one by one. I went with the Noctua NC-U6 Northbridge heatsink, very small but tough device. 3oh6 recommended a fan to install on this but I'm unsure I need one if I'm only running 425 FSB? Maybe I do, as I said, I'm unsure.

Well I may sell my HPA on eBay, but then again I may save it incase I have to send the board back to Asus for warranty claims. I'll get lots of photographs of replacing the HPA with Enzotech copper heatsinks, this is a great thread and I've learned a lot from it. I want to extend this thread by posting more pictures and potentially helping others in the path to lowering temperatures by replacing the HPA with alternatives.

Thanks again.

[Ozzfest05]

had to tinker some settings to get this completely stable for longer torture test

[rob2k]

Hello ci2kla and - I'm sure there is more reading to be done on the tRD (Performance Level) and my understanding on this is very limited. I have had mine always set to AUTO which sets it to 6. I tried 5 manually once and it did not boot past the bios post.

Well I may sell my HPA on eBay, but then again I may save it incase I have to send the board back to Asus for warranty claims.

We should all send our HPA's back to Asus so they realise what a cr@p job they have done but as you say its probably best to hold onto it for warranty or in case you sell the board in the future as all of the new replacement cooling can be taken off and used again.

What CPU and O/S will you be using ?.

I plan to fit SLF-1 at the w/e as from Expat Griz it sounds like the S/B will run at least 10 degrees cooler than with the CNB-S1L. To be honest stick with the parts you have so far, once the system is built if you are unhappy with the performance of any part then look to swap them out. Memory reviews are a useful guide but only if they are using a similar platform, CPU architecture and cooling as the restriction may lay elsewhere. To answer your question about running memory slower than its rated speed then see post #1471 - generally it can be ran with tighter timings and less voltage and then the extra headroom may be used later after a change elsewhere in the system eg, if you went to W/C.

Try PL6 and pull in the channel A and see what you can get. If you can POST but BSOD in windows you may need a pump of vNB or so IMO.

BTW, does anyone have clue on my E8400? I can't pass ORTHOS still...small FFTs failed in the first loop. While using single core version go on 11 hrs without a problem (only stress one core). Please help...
