Even if it means replacing my RAM.
I am guessing I would require a bump in NB Voltage, to around the 1.33-1.45V region for 8GB @ 1600FSB?
Leeghoofd did you spill LN2 on your board?
Fingers crossed you get the problem resolved...

Jup that's the one... picking it up on thursday, I want to see the official paper. He said they found LN2 traces on the board and some erasor leftovers in the socket... The latter which would be very awkard to me... But let's just wait and see before going bezerk.
Anyway I will take the board to the Asus tech conference in Frankfurt. Either someone will stand up and tell me what designed for overclocking really means and repair the board. Or it will soar around in the room :p Ninja style :p
Ratz....too bad I'm not home....you could of stopped in for a bevy...I'm 5 minutes from their shop... :D
Good luck with it in Frankfurt.... :up:
So then guys, what settings are you able to realistically obtain with 8GB and a QX9650 on the Rampage Extreme with Air cooling (Xigmatek S1824EE) :)
Thanks
John
I think you are going to have to be the guinea pig John. I have searched the thread, and can't find anyone pushing a quad and 8GB. Dual and 8GB yes (DerekT) and Quads + 4GB too (few of us but nothing really well tested).
its gonna be a pain but you have unlocked multi so you should do around 4.0Quote:

It looks like I shall be the guinea pig unless some Xtreme lurker is hiding in the shadows somewhere with a Quad, 8GB and a Rampage Extreme ;)
Ah zsamz_ it sounds impossible to me as 1.60V on the NB is way beyond my comfort zone.
I had a little play this evening, but to no success!
I get failure in memtest #5
NB = 1.31V
DRAM = 1.80V
DRAM Latency. 8-8-8-28-10-88-8-8
Now word of warning, it is wise (and yes you guys already know this, but I thought I would type this anyway in case the novice like myself is reading this) to MANUALLY set your CPU PLL and other voltages.
FYI @ 400FSB the motherboard [AUTO] For CPU PLL IS 1.70V!!!! This will most likely degenerate a 45nm CPU in a short period of time.
I personally would not be comfortable taking the PLL over 1.58V, but that is just me :confused:
I may visit this over the weekend, perhaps slacken the RAM off somewhat and introduce more DRAM Voltage and maybe a bit more on the NB. Perhaps raise that PLL to 1.56 or 1.58V (as I tested on 1.52V)
I can confirm though that this board is leaps and bounds better than the horrific P5E3 Standard!!
John
john i never ran below 1.63 on any of my x48 boards;)
i liked that xtra pl:D
its after 1.7 i be scared :rofl:
but i've pumped in 1.8:p:
btw 1.55 is really safe
nb gonna get hot with 8 gigs;)
:yepp: my e6850 degraded @ 1.67pll some moron poopsted it was ok n .....my 4.2 chip can only do 3.99 now took 2 months
avoid auto if ya can is :up:
Basically, errors in test #5 are ram related - try more voltage, different timings. Errors in test #4 and test #7 are often FSB/NB related - try changing vNB & vFSB, sometimes though its ram too. I found the REX will error in test #4 if you have vNB too high also, and they are quite heat sensitive (this may have been the cause ie: high temp and higher than necessary voltage). Once it gets over ~56*C you may run into issues as a result so make sure to actively cool the NB.
I found though that my board would do 625 - 630 FSB at vNB less than 1.60v (with a dual core obviously) and it just didn't need any more unless I was going for PL8 or something, so try other things before just cranking up the vNB.
Thanks for the input and advice guys :)
First of all I must say this is a VERY fine board. I have not had a lot of time to do any serious tweaking and OCing. But I have found with such a small bump in NB voltage (up to 1.27V) I am able to complete Memtest! @ 1600FSB and 1600Mhz on the RAM with a QX9650! (Quad Core).
There were a few other settings required for this to work.
RAM CAS Timings.
9-9-9-28-10-88-8-8
2N Command Rate.
CPU PLL = 1.56V
CPU Voltage, = 1.30V (I might be able to lower this a bit)
FSB Termination Voltage = 1.20V
CPU Ratio = 8 (for now to try and eliminate limiting factors)
Static Read = Disabled
Dynamic Writes = Disabled
Common Performance Level = 8
DRAM Voltage = 1.82V
Here is my memtest pass
http://img219.imageshack.us/img219/2...16008gb.th.jpg
Why a CPU ratio of 8 I hear you say. Well I have found that my system is 100% Stable with a ratio of 9.5 on STOCK FSB/RAM. (1333Mhz). So therefore I tried to find a clock similar to this with the FSB of 400.
It is not all good news as I cannot make it through 10 runs of linx. I get to run 8 and suffer an error, however I am able to gracefully close linx shut the PC down so at least it is not a BSOD or anything like a freeze. I am sure that this might only require a slight voltage adjustment somewhere (perhaps NB) to get me through.
However the fact I can get through memtest shows I am heading in the right direction. For those of you who do not believe how useless the P5E3 Standard is, I was unable to run 8GB at STOCK without an increase in NB voltage AND DRAM VOLTAGE... even then I would suffer random application crashes. After swapping out every component and testing in other PC's I finally found the issue was down to the board. The Rampage Extreme is a breath of fresh air. 1.25V on the NB is fine for QX9650 x 9.5 and 8GB of RAM @ CL8 and Performance Level of 7. This is completely game and linx stable and memtest stable.
However there is a slight BIOS Bug with the Rampage Extreme, which ASUS resolved for me on the P5E3 (so I may have to re-report it for this board). IF you set a manual multiplier which is higher than the default, when you COLD BOOT you have an error on POST about the CPU VID not matching the Ratio :(
Here is an example of the error message
http://img219.imageshack.us/img219/6389/imag0159.th.jpg
John
Nice work so far John, keep at it.
Thanks CryptiK I shall try again at the weekend :)
If anyone else is able to reproduce the manual multiplier "VID" error message I took a picture of (which only happens on a COLD boot when a manual CPU ratio is set), please could you also report it to ASUS TSD. I have e-mailed them, but as of yet I have not had a response.
As with all things, this issue probably will only be resolved if a number of people are able to reproduce and report the problem.
Thanks
John
Yes I have the VID issue too with the QX9650, had it too with the P5K and P5Q Dlx boards...
Best suitable on my board is 9 X 450FSB and 4GB 1800mhz C7on the Rams. I use strap 333 and clock twister light to reduce the stress on the NB. If I go over 450FSB I need to lower the ram clocks to remain stable and use strap 400. But this REX's NB isn't the best... too bad my good one went down...
Ahh you have reproduced the VID issue too?Quote:

To me it seems very sloppy that they fixed it on one board, but did not carry over the fix to all effected boards.
So on air would you guys say that keeping your NB volts below 1.4V is a good idea?
John
If your rig is fully stable with only 1.4 then that's great. Mine needs 1.55NB voltage, NB temps go up to 50°C (with added active fan on the NB)
I wouldn't mind pushing 1.5V through the NB for a daily setting. On water i pushed up to 1.78V for benching with no ill side effects.
Thanks guys :)
The problem for me is... temperature!! As others have correctly stated 8GB puts more stress and strain on the NB.
At Stock Clocks my NB reaches a staggering 51C during Linx (20 runs of "6896MB") and up to 54C according to the LCD Poster during heavy gaming. (Yes a Single PCB GTX 295 can make the NB rather hot when it is working hard).
When I raise to 1600FSB the NB reaches 59C during heavy gaming of 1hour and 52C during Linx.
I think 8GB + Quad Core really does hamper what you can achieve with clocks...therefore I am not going for anything Xtreme, just something which increases my performance mildly.
Leeghoofd you are a dab hand with a QX9650?
What Voltage would you suggest for the Vcore (on Air with a Xigmatek Heatpipe cooler)? I am aiming to keep bellow 1.3265V Vcore and 1.58V on the CPU PLL. Ideally I would like to acheive 3.4Ghz with 1600FSB, however I may have to sacrifice on the RAM clocks here.
Interestingly I have noticed that raising the multiplier requires a BUMP in NB volts (not CPU volts). Is this because >3Ghz Quad Core is more taxing on the NB?
Perhaps I am being too ambitious, but I am certain Intel did make a Xeon based 45nm "Core" series CPU which ran @ 3.4Ghz 1600FSB so in theory I could aim for this :p
Zeus
How hot did your NB run on air? and how much did moving to water cool things down?
Thanks again
John
Did you change the thermal compound under the stock heatsink yet? If not, do it, it's worth 10-15°C less for me. The stuff Asus uses is very very crappy and poorly distributed.
Concerning NB volts, I'm not using the REX for 24/7, but I have been running many hours tuning for a LCC at 1.55V, I haven't seen a sign of degradation yet.
john i had a moded katana3 on my nb keepin her below 40c @ 1,63v
Thanks for the advice Dan,
I must admit I did replace the thermal stuff already on the polished side of the NB with AS5, however I did not take the whole heat pipe assembly off as I was worried about breaking something..
Anyway I might be on the way of getting some system stability.
Here is what I have managed to achieve so far.

As you can see I am on the way to getting stable. Once I am certain the system is stable I will post my settings in case they help people with 45nm Quads and 8GB.
I think setting "Clock Twister" To Moderate is a very good start to gain stability with very little in the way of Voltage Increase on the NB.
John
I think I might be getting there guys... any ideas?

John is you test with LinX make sure you set ram to max or a higher value then just 1024Mb, this should take over 30 minutes easily... I always test too with Hyperpi 32M (4 instances)
Thanks Leeghoofd
Any ideas as to what could cause a reboot on loop 12 of 32m hyper pi?
I have just raised PL to see if that helps...
EDIT: YEP I think that has done the trick as 32M hyper Pi's using 4 processes has completed :)
I'll keep an eye on things now....see if games even work!
John
Raising PL kills performance. Reboot is more cpu related i guess. Try more Vcore.
Think he needs more NB volt Eugene , he's only at 1.4ish or so... with 8GB and a quad that's already nice... I would try 1.5ish with an active cooler...
Hmmm, yeah that's sounds a bit too low but not enough volts to the NB usually causes the system to freeze, reboot is usually cpu from my experience. ;)
Thank you for the comprehensive advice Zeus and Leeghoofd
I have made slight voltage adjustments. (very small bump in vFSB and vCore)
Since doing this I have been able to perform a 32M Hyper Pi :)
And I performed a 20run of Linx using ALL Free RAM ~6800MB
http://img221.imageshack.us/img221/9...0fullc7.th.jpg
As you can see the CPU gets rather toasty :p
What do those results look like to you guys?
PS My NB volts are 1.31V :p and my CPU Core is 1.28V, PLL = 1.56 and VTT = 1.23V
Thought I might add this for good measure...

big problem - HELP
Hi, i think i might have blown one of my REX's
it doesn's post anymore, when i poweer it up it does nothing.
but if i take out the 12v pin plug it starts to run the fans and such but
doesn post.
this makes me think it's a short of somekind, not sure. I have read about this problkem in several forums but there was no solution. So if anyone has any suggestions please help
the pins in the socket are all fine... i have tested it with several cpu;s
done all thzat process of elimination stuff to no avail....
this board was a 630fsb monster i hate to loose it....
there wans;t any sparks or any blown components so i am hoping that there might be some hope somewherer...
thanks in advance for any help anyone can give me.....
best regards.SV
Ouch Viper that sounds pretty terminal :(
Have you tried POSTING from the Other BIOS?
There is a flip switch on the board where you can determine which BIOS to boot from. Try switching it to POST from BIOS 2 and see if that helps?
Another suggestion is have you tried using a different PSU?
(yes it might sound stupid, but sometimes PSU's after time can degrade, especially if they are under a lot of load for a long time)
Aside from these ideas, I am a bit of a newbie when it comes to anything technical. I assumed you tried POSTING with just one stick of RAM? and removed all devices other than your VGA and then even swapped ports the VGA was using.
What does your LCD poster say it is halting on?
John
SV - I replied your other thread. Best of luck.
John - that's not to toasty, theres more in it :D
Been doing some work finding settings for my Q9650/REX/4GB Ram as well after throwing the system together a while back. Seems to be going well so far. If I gave it some more vNB I think PL7 is doable. At these settings with PL7 everest read is 11 2XX MB/s :) Not bad for a quad with 4GB on an X48.
Current stable(ish) settings are: 4GHz (445x9) @ 1.216v (load) | 4GB @ DDR3-1780 MHz | 7-8-7-20 1T | 1.62vdimm | PL8 | CT Mod @ 1.36 vNB
LinX all mem
http://i720.photobucket.com/albums/w...d136vNBpng.jpg
25mins Large FFT testing (this ran for over 2 hours before I stopped it to do other things)
http://i720.photobucket.com/albums/w...d136vNBpng.jpg
Everest at same settings as above stress testing
http://i720.photobucket.com/albums/w...d136vNBpng.jpg
I am VERY impressed CryptiK :)
I am also close to stability, CLOSE and I sense VERY close. This is what I can do :)
1) 20 x Linx ALL Free RAM (~6800MB)
2) 3 runs of Memtestx86.
3) 5 runs of Metro 2033 Benchmark
4) 5 runs of 3dmark06
5) 5 runs of 3dmark Vantage
6) 32M Hyper Pi all processors (4)
7) Auto(1hr) OCCT 3.10 stress test
However After ~2hours of playing Just Cause 2, mid game I got a Random Blue Screen Entitled "System Service Exception" :(
What really impresses me with your settings CryptiK is you are not really using ANY DRAM Voltage at all (I am currently camped on 1.85V) AND you are running at 1T!! I am unsure as to whether I should treat the BSOD as a One off, or look into playing with more settings. If so, what would you suggest I alter?
At the moment my settings are perhaps a bit too aggressive?
RAM is set to 7,7,7,24 With a Row Refresh of 88 and a Command Rate of 2T
This is At a PL of 7!
NB = 1.36V
DRAM Volts = 1.85V
Aside from that random one off Blue Screen I am VERY impressed with how this system is running with 8GB @ 1600Mhz
John
Thanks, yeah it's not bad, better than I thought. I honestly didn't think I'd get DDR3-1780 MHz CL7 stable at 445 FSB at PL8 especially with a vNB of 1.36v. I'm getting heat limited with the cpu though, it's a very hot 1.2125 VID and I was getting 70*C on all 4 cores in LinX. The NB is also hitting 66*C as I can't easily actively cool in while in the case. Aircooling is weird compared to my i7 water setup.
My ram voltage is all that the Elpida BBSE IC's need at those speeds/timings. My kit is quite good too it seems (just using 2 sticks from a 6GB triple channel kit).
For your instability, it could be anything, but I'd first try increasing NB GTL to about +30mv if you haven't already. You could also give it a notch or 2 more vNB then see what happens during gaming. I think that 8GB/400 FSB/PL7 is probably stressing the MCH pretty hard.
EDIT - Oh BTW I would highly recommend you run some Prime 95 large FFT/Blend. It was always the hardest test for me to get to pass on this system with a quad and 4GB ram.
Thank you very much Cryptik. I have changed my NB Gtl value to +30mv. I will run that prime 95 test for 2hours? and see how the PC copes. I guess I may have to go to PL8 if I cannot get stable as the Intel spec for X48 does suggest PL8 for 1600Mhz Memory speeds.
Thanks again.
John
BTW how do you determine what your RAM IC's are?
Yeah 2-3 hours is ok for initial stability testing. If you're on the way up speedwise, lowering PL, testing new timings etc just an hour or so to show you're on the right track is what I do tbh. Once I am trying to really dial in a specific setting(s) I run it for longer.
I'm comfortable at PL8 at DDR3-1780 so I think you should be able to make PL7 happen. With no NB GTL dialed in you were doing well as it is, I think increasing that to +30mv will help a lot. Helped me with my setup, and helped me I was doing 630+ FSB SPI32M runs on DICE with my 8600.
I knew mine were BBSE when I bought them as the first rev was reviewed and heat spreaders were removed. Myself and some others jumped on them right away. They since changed to other IC's as most ram does. You've just got see a few people report the same IC type for a specific revision of stick/kit and jump on them and hope for the best.
If you want to know what yours are, you have to research or look under the spreaders but it can kill sticks if you take them off wrong. Unless you know how, I would't risk it. You can sort of tell what youre running by how they behave too.
I started to get major stability issues. Could not pin it down either. upping PL and CAS. did not sort anything. It's strange can Prime95 for hours. Full linx 20x. and 3 passes of memtest as well as OCCT. but random and hard to repro gaming issues are preventing full stability.
NB can reach 60c in GTA IV! Game is stable yet occasionally artifacts yet resumes normally.
Weird or just more vRAM required?
Thanks
John
Possibly. Have you tested ram with the windows based app HCI Memtest? You'll need to run 4+ instances of it to test 8GB, but's its harder on ram than anything else I've used IMO.
Is your vid card stable? If its overclocked too, tried gaming with it running stock?
I think your NB is crapping out due to temps, my NB doesn't like temps over 60°C at all. When gaming the VGA will heat up your case, did you try to add more fans to dump the heat out of your case?
uh oh mine is not booting :(
Starts up HDD light is lit, fans keep spinning but no display and it just stays running like that.
Tryed both bios'
what is the flashback jumper on the bottom supposed to be on? all the way to the right?
Any idears?
i never saw my nb temps go over 40c even @ 1.7vQuote:

With PostFX, Displacement Mapping and XtremeBurn mode enabled.
What is really odd is that I have the same issues with Just Cause 2 when my Processor and Ram are at stock speeds.
I also do not notice much of a difference in NB temperature between Overclocked and Stock. (We are talking a Max out of 57C Vs 60C)
It is certainly making me think that the GTX 295 Single PCB is turning my case into an oven because 20 runs of Linx using the Full amount of Free RAM only heats the NB up to 54C.. and it DOES cool quickly after Linx has finished.
Gaming seems to heat things up and it takes longer to cool down.
I have 6 Case fans. (120mm Gentle Typhoons).
With the exception of the NB Temperature, I do not think my CPU or even Graphics card temperatures are that bad. I have fitted the ASUS Fan to my NB (which is pretty loud actually), and that does not appear to have made any difference to temperatures :(
I am putting the Just Cause 2 issue down to a driver bug as Google shows other people have the same issue. However the GTA IV thing I feel certainly was NB related as this NEVER happens at stock.
oddly 3dmark Vantage and 3dmark06 can run in loops of 5 with no problems at all.
I have experimented with a variety of strap settings and NB and DRAM Voltage. It is odd that I can pass 2 full runs of Memtest with 1.28V on the NB and 1.76V on the DRAM. Yet require at least 1.33V on the NB and 1.88V on the DRAM to be 3dmark loop stable :P
I have my PCI-E Clock set to 100Mhz, I did dabble with 101Mhz as in the old days this used to help with stability (Pentium 4 OCing). However for some reason I get instant BSOD's on Windows Logon with PCI-E raised by 1Mhz.
I was hoping by now ASUS would have released another BIOS for us to play with with the Refresh Period settings and some tweaking for 8GB + Quad Core.
I may give up on this, unless you think I should try and play with CPU GTL's and DRAM Skew :P
Surely some people on here have had a dabble at 45nm Quad + 8GB on this fine board?
John
sure does sound like your gfx card though if you have the same issue at stock settings for everything else. using the best drivers?
Hmm thanks, for that CryptiK I shall look into the issue further.
Even with underclocking and 1066Mhz RAM speed I get this issue in Just Cause 2 Only!
What slot do you guys use your graphics cards in?
I have reported it as a driver bug to nVidia :P
John
I use the top most pci-e slot. I haven't gamed on it as it just has the basic testing apps on it atm but it passes looped 3DM06/Vantage without issue. I'm actually running at PL6 at 445 FSB/DDR3-1780MHz CL7 so I don't think theres an issue with the NB being pushed too hard by gfx unless of course 8GB makes it a whole lot harder. You are getting the issue stock, so I'd be inclined to guess its a driver issue with that game only. Can you play Crysis/BFBC2 ok? They both are pretty tough on the system.
hey fellas after using this board for at least a year now I settled with my dominator 1800 running at 1600 pl5 7-7-7-20 1N the cpu is an e8500 at 3.8. Ive tried to get them up to 1800 with no luck, havent tried skews yet if anyones got a good article about how to adjust them. I want to try to get my cpu running faster and while Im at it get some better ram that can actually run a 1800.
I just wanted to check if there is any place for us x48 people to get new memory or is all the high voltage stuff discontinued. can we use any of the new low voltage stuff?
Is you E8500 a C0 or E0? If it's the latter it should do 4.3 - 4.4GHz on safe-ish vcore. Your 1800 MHz ram should do 1800 MHz, but without knowing model/IC's I cant advise some timings to try. Back it off to 9-9-9-X and see if that helps.
Skews are a trial and error thing, there's articles that tell you the principle of their operation, but as to what settings may help you, that only you can work out for your gear.
You most certainly can use 'low voltage' (by this I assume you mean 1.65v X58 kits) on the board - I'm using 2 x 2GB G.Skill Elpida BBSE kit at 1.62 vdimm for DDR3-1780MHz 7-8-7-20 1T. There's many P55 kits that should work too.
hey man, my e8500 is an EO Ive had it running at 4.33 480x9.0 v1.3 and was able to keep the ram at 1600 but not as fast as at 400fsb. Thats fully stable though without much playing around.
Ive tried loosening the timings and upping the voltage to get 1800 without any luck its on watercooling so heats not really a problem but compared to you guys im running higher voltage on my ram 1.98 but the nb is stable at 1.54. I just think I got a bad set of dominators but they rip at 1600.
Thats good news the low voltage ram works on our board. Any recommendations for 4gb @ 2000mhz Thanks for the help
gonna take a chance on these G.Skill Trident F3-17066CL9D-4GBTDS 2x2GB) DDR3 give us a heads up if I should rethink.

excellent. they are only cl9 but they should do the job lookin forward to see what they can do but really just looking for a set that I can tighten down at 1800 eventually. with a bit of luck ill get a decent set.
I have stability at 366Mhz FSB default multiplier :)
I will push it some more over the next few days, the key is to actually use a bit more DRAM voltage, but not so much on the NB.
So far games, benchmarks, Linx, OCCT and Hiper Pi 32M are all stable... even Just Cause 2 as the Steam Client update resolved the issue (apparently memory corruption was resolved in a steam client update, since then I have not had an issue with Just Cause 2.. even with the mild 3.3Ghz OC @ 366FSB).
John
Right, hopefully that resolved it, if you are stable with everthing else wind it back up and see how it goes.
Thanks :)
I worked my way up to 375FSB and everything was stable, then went for 390FSB. Was 3dmark Vantage Stable, but got instant Linx failure (Linx stopped unexpectedly not enough free RAM) ;)
Perhaps a bumpage in VCORE from 1.25V upwards is required?
Not had any crashes, but will tinker with voltage over the weekend.
Thanks for your advice :)

Hey again I just wanted to ask a few questions.
On our board how far is the safe overclocking voltage limit on the REX for 1.65V ram
Do you guys use load line calibration? mines always been disabled but I heard some people use it.
The ram I got listed above wouldnt post at anything above 1800mhz would that just be incompatibility or should I RMA it?
Thanks for any help.
some REXes only like particular straps, if possible cool the NB actively (gains far more stability) I ran my Q9550 at 3.8 with 1800mhz C7 rams daily at 2.1Vdimm (Micron DGTR).
You can't define a safe ram voltage limit... some ram chips don't mind, others go down. And even then coz someones says eg 1.8 is no biggie, doesn't mean it works. If you set it , you are responsible. I'll try the Gskill Flares on the REX and see if they can do 1800C7. Keep in mind that with 4Gb, you might need to alter some vital bios settings like NB voltage and co.
Personally I always used 1.375VCore with LLC on with the Q9550. ram perfectly fine at 3.8Ghz... CPU is still alive and so is the board...
use 1.68-1.72v
1.65 is out the window:p:

It was difficult, thank you to all of you who have helped in this thread. A big thanks to Alien Grey for providing me with a BETA/Alpha BIOS for the Rampage Extreme which boosted my 3dmark06 score by 1200 points! (and eliminated the dreaded microstutter!)

Try to run vantage without Physx on John, see if the CPU holds up ( now the GPU did most of the work ), let's go 3.8 or even 4ghz !!
congratulations on a nice stable overclock john, Is there any chance I can get that BETA/ ALPHA bios off you... I think micro stutter explains some of the symptoms that Ive been having.
Very nice, I'd also be interested in this BIOS you mentioned.
Which BIOS, 0002? On my board that BIOS didn't work most of the time, whenever I changed the tREF value. Or is there a more recent beta BIOS?Quote:

I don't think that's possible with the BIOS multiplier issue that he was talking about.Quote:

It needs a power off/on just like changing memory timings and it doesn't do that so the best way to change tREF is to do a Clear CMOS, load your overclock profile and than change tREF.Quote:

My guess is 002 BIOS contains a compatibility fix for either 8GB or GTX 295 as the difference in results is quite big.
Just thought I would upload some Linx fun..

Here is some Vantage with Physx disabled.

I do not think I will try for 3.8Ghz as my CPU is right on the edge (temperature wise and probably voltage wise too!)
I will upload settings later today (screenshots of the BIOS settings)

Hey all!
I bought fev mobos witch is dead.. Ofc one is RE since i writing here about this ;)
So i found one broken component on it and here is a pic of it. Now i only need to know what component is that and if someone knows its value it would be great help! (Marked red in the pic) :) I cant look it myself so good when its already BLOWED away from the board :D (Only black PCB left on that place?
The pic (If this works, if not then i upload it somwhere else)

Hi guys
Xtremesystems' Guru Alien Grey has found an amazing tweak which may help you achieve higher overclocks.
To summarise Gigabyte P45 boards which can get pretty high clocks have a default MCH Read ODT of 11, yet our boards have a MCH Read ODT of 8.
Sadly due to ASUS' BIOS design (or lack of), there is no way to change this value... however Alien Grey has discovered that you CAN change this value using a tool called Bar Edit.
You can download Bar Edit from here. I believe this tool is written by that really clever and helpful Felix, the author of Memset.
Once you have installed Bar Edit you will need to restart your PC and follow these simple instructions.
1) Open Bar Edit
2) Locate memory address FED14290 (you can locate these addresses by scrolling down the list).
3) look in the column 0C for a value of 778
4) Change this Value to 77B
5) Click Write
6) Close Bar Edit
Your MCH Read ODT should now be 11T.
By the way does anyone know where I could purchase a replacement NB passive cooler to fit on this board?
John
Anyone else tried this out yet?
I am wondering if you have any advice on cooling the NB, my RE passive heatpipe has somehow broke? (the glue wasnt very strong and the bond wasn't that great).
Was looking for some sort of heatpipe which would fit on the existing mountings?
I could repair the passive heatpipe cooler, (and have done a repair with thermally safe Epoxy), but it has not don my temperatures any good :(
So I am probably going to have to scrape the passive accessory pipe and thing of a better solution?
I contacted ASUS support, but they say that the accessory passive pipe is not available separately....which sucks :(
John
i got a rex again:D
just doin some max clocks for now
i'll do some memory clockin laterz:D
Curious...
is there any way i can make it so that you don't have to press F1 at startup if you don't use an air cooled system?
i'm on water and would love it if there was a way to switch that off other than pluging a fan into it that does nothing.
just turn cpu fan monitoring offQuote:

Cold BOOTs give me a System Service Exception BSOD or an iastore.sys BSOD.
Providing I do no cold boot the system is entirely stable for more than a day. and in this time I can play games, Linx, 3dmark loops, etc without a hitch.
Any ideas?
John
Hi, I need to bump this thread up.
Today I got a new REX and a new pentium cpu, it seems this board won't allow me to overclock a 200fsb cpu.
It can boot with all settings set to auto but if I change a single thing it won't boot.
reaseat the cpuQuote:

Im pretty happy about this because Im worried that it will burn my hardware out very fast. For example not exact but CPU volts go up to 2v dram 2.5v northbridge as high as it will go same with southbridge.
It only changes back when I reset settings.
Is this a bios virus that makes the hardware try to kill itself or what?
maybe its the boards way of trying to tell you to buy new hardware...
has anyone else got the same problem?
friend of mine had that issue LONG ago on an old athlon therough bread system. he was playing starcraft over battlenet and someone got bent about my friend winning the round and the guy some how sent him a bug that did something almost exactly the same. though it wasn't in intervals, it effected him immediatly and constantly on every boot up to a point where he would have to redo his bios settings every time he turned on his system.
so you're not entirely wrong by thinking it's a virus, it very well could be... all the virus needs is access to your PLL clock gen, of which if you use anything higher than basic windows then it does have access to it. but it also could be a bios issue or a degrading circuit somewhere also...
yeah in the end I thought it wouldnt be the exact same changes every time unless it was programmed in there some how... anyway Im not pretending to know why it happens.
Its not like this just started happening recently its been going on for about the last 6 months. I wanted to make sure it was a real problem before I posted it.
Ive tried changing bioses though and it doesnt seem to fix it. Anyway its not critical, just a problem im trying to fix, checkin if someone else has the same issues?
I am not too sure how true it is, but I have heard that some 4GB modules work on this board, meaning that you can have 8GB from only 2 DIMMs!
Can anyone confirm this?
I am thinking of replacing my RAM as I am not 100% sure, but I think it is becoming defective as CAS7 is no longer stable... not even @ 1333Mhz when these sticks are rated for CL7 @ 1600Mhz!
John
i will be testing 4bg modules hopefully by next weekQuote:

Awesome zsamz
If you do manage to pop 8GB of that onto the Rampage Extreme please do post your results (even if you cannot POST ) :p
Thanks
John
Have you got your new RAM yet zsamz?
John
@ rotamonkey - I have heard of this happening with the REX, try reflashing the BIOS to the latest version. Flash the BIOS while at stock settings.
i got the ram long ago lolQuote:

i can solve all of your problems you guys,just send me your REX's and be done with it,problem solved:rofl:
Thanks have reflashed bios multiple times but might have overlooked returning settings to stock, bit of an issue because with my setup the board doesnt like to post on stock settings (ram issues i think), but maybe thats why ive got the problem and noone else does.Quote:

Yeah the memory compatibility on this board can be fussy (as with all ASUS 775 x38/48 boards).
I must admit I am also relishing to see what zsamz results are!
4GB modules would rock the socks off as having all 4 DIMM's populated does seem to significantly limit OC'ing (as I have found out by using all 4-DIMMS) and brings unforeseen results.
John
i will get to it soon with an e8500Quote:

but i think you dreamin if you thinkin of clockin with 4x4;) unless the rex loves the newer psc chips
but you gonna need some serious juice on the nb:eek:
i have to get to it before i get my p67-ud7 n 2500k;) lol
john with 2x4gb max speed is 1800-1850mhz cas8
with 2x4+2x2=12gb max speed is 1760-1800mhz
the 2x2 set is gskills 2200 cas7
cpu was e8500
its cool havin 12gb on x48:D
if you buy 2x4 get the 1600mhz 6-8-6 stuff
takes forever to memtest so i only did a few passes of test 5 since it was on test 5 that i was getting errors with 2x4
memory top speed gonna be 1600-1700mhz with a quad;)
i'm not puttin in the q9550 cause i have to redo loop to put it in:(
i have a gigabut p45 for the quad :D
Thanks for the test zsamz
Are you able to provide a CPU-Z shot?
What volts are you pumping into the RAM and the NB for 1600Mhz speeds?
Would there be a particular brand of RAM which you would suggest for a decent 8GB 1600Mhz Kit?
Thanks again.
John
i was pumpin 1.65 into nb:p: 1.7 into ramQuote:

its 1.5v stuff:eek::up:
mine cant do cas7:mad: and they 2000mhz kit
more juice has no effect
but its stable with 1.6v
thats awesome that they work, definately want to give this a go but wasnt your NB frying at 1.65? was this just a quick test setting or couldnt you get it runnin any lower than that? mine seems hot with water cooling on the NB at just over 1.5v...
Im probably a bit nervous about that because the NB on my last x48 board had a meltdown at just over 1.5v but no WC on that setup.
i have a block that i moded for the nbQuote:

my nb hit 36c on load;)
all my x48 boards either got a better nb heatsink or watercooled
even 1.7v dont scare me;)
with stock cooler n 1.4v it got too hot for my taste
heh heh nice one, gotta love that type of moddin. Ive gotta do the same to mine or at least reseat the stock heatpipe setup, I heard thats good for about 10 degrees cooler temps. my nb's on 1.53v and at load im gettin 53 degrees and worse on hot days.
got plenty of AS5 and thermal tape around might be time for a project...
I was going to say that those NB volts are very high!
Ideally I would not want to go over 1.45V
My NB seems to run quite hot with 4x2 DIMMS and I was hoping that perhaps 2x4 DIMM's might cool it somewhat.
Thank you once again for your informative test results zsamz
The only issue is I can only seem to find the Ultra Low Voltage 1.35V edition of that RAM in the UK :(
Seems we have lots of Corsair and G-Skill Rip Jaws, but snipers are rare and the snipers we do have are 1.35V
