Still running 1.52 daily here stock heatsink with an antec spot cool cooling it... temps under load are 51°C still running strong with 2 x 2Gb 1600C8... QX9650@4ghz quad at 400FSB...
I'm getting a 12GB Sniper 1600C7 kit for review John... keep you posted how they work on the old hog...
@rotamonkey
I guess you have that swiftech block on the original heatsink arrangement, therefore the high temperature.
That original heatsink arrangement is no good, if you want to get that temperatur down I suggest you switch it for something better.
Back in the days when i ran my REX I used a koolance CHC-122 for the MCH, it was in the same loop as the CPU (Q9650) and during full load the MCH rarely went over 40C even though I used 1,60v +.
Awesome, thanks Leeghoofed :up:Quote:

John
do you guys think a swiftech GT cpu block could be modded to fit the NB on the rex?

1.5v snipers are 95$:eek:
yeah definately goin to have to do something about this, its gettin colder here now and the temps arent as bad anymore but under load definately around 50 cant believe you guys arent even cracking 40... holidays next week so Im gonna pull the board and see what I can do...Quote:

I am just thinking as a lot of manufacturers tend to list the old and not very easy if at all possible to get hold of RAM.
Would be nice if they did test the newer RAM on this board. :(
John
don't think it will be interestign anymore John, hardly anyone uses this board for 24/7 ( I still do at my parents and you : that makes two :p )
You have a very good point there Leeghoofd :(
I would like to try and think of a valid counter argument, but facts are facts and the amount of people who are still on 775, yet along Rampage Extreme is diminishing everyday.
I am clinging on until Skt 2011
I eagerly await your test of the 12GB Kit on this board. If possible please could you test with 8GB as well as the 12GB :)
ASUS gave me a BIOS which fixes the VID Ratio error with the QX9650, I am happy with it, they also updated the RAID ROM too. BUT took away TREF :|
John
Anymore 4GB module test reports guys?
John
shame you cant get the snipersQuote:

I was using a REX 24/7 in gf's pc up until a month or so ago. Not many people left who would be though that's true.
16GB for $135, no matter how crappy the speed/timings are thats good value for a cheap desktop. SB just loves crap ram too so thats where the market is now.
yup sandy dont like the good stuff lolQuote:

I've been testing my Dominator GT 2000C8 on my REX for the first time yesterday and today, trying to get a fast 32M at 2400MHz.
This is the result:
http://img41.imageshack.us/img41/815...dr31600cl6.jpg
My goal was to hit 17m15s ( or lower of course ), as you can see I'm not quite there, but hardware-wise this is pretty much the limit. This was done at 1.55V Vnb and 1.70V Vdimm, I tried to get tRP 4 at up to 1.75V Vdimm, or tCL 5 and/or tRCD 5 at up to 1.60V Vnb and 1.80V Vdimm, but this didn't work out.
If you have some ideas on how to improve the timings I'm all ears! :D
Software-wise this is also almost maxed out. A fresh OS might give me small gains, but I don't think it'll gain me 2 seconds.
In case anyone's interested in the bandwidth, here's an Everest shot right after reboot ( same settings as the 32M above ):

That is good going Don Dan :)
Has anyone had any luck with Ubuntu on this here board?
I cannot seem to BOOT Ubuntu unless I disable ACPI via a command line?
(and then I am stuck with crap performance and 1 core)
This is the LIVE BUILD DISK I am using
and I have tried both the x86 and x64 distros from here
I still cannot get Ubuntu to get to the desktop after the splash screen unless I boot with the disable ACPI option.
HOWEVER the distro I am using works fine on a few other PCs :(
John
Its just you ;)
I have some results here: Hyper testing on REX
Maybe your ram just doesn't like tRP 4?

I guess that's the truth, or it's the board. :shrug:
I already have an idea on how to improve the score, I'll give it a try again some day. :yepp:
I've still got 5 boards......4 of them working ....one died on the front lines after 6 hours @ -135. :D
One day soon will bash them some more. :up:
I still have mine too and a nice dual core. Just haven't used it since it was in my GF's PC running the Q9650, before that it was all insulated up for fun times. Hopefully one day I'll fire it up again!
Tried another kit of ram Don?
No, not yet. I might try that when I have some free time again, I still want to beat 17m15s! ^^Quote:

Try BIOS 0403, and get another kit on there see if you can tighten it up. You using 266 strap? Pull-ins on or no boot at tRD 5 with them enabled?
At 6 x 400 and DDR3-1600 its very limiting, can only tighten so much. Its probably down to OS tweaks if you want much more speed. Why the 17m15s target?
That score was done on the 0403 BIOS! ;)
I'm on the 200 strap, but now I think the 266 strap might have been faster. I tried all the Pull-Ins at tRD5 and enabled them one after the other, but they all resulted in no boot, even at higher Vmch and Vdimm.
I'll try the 266 strap and also another kit when I have my semester break.
The score was done with all the OS tweaks I know, no magic left. :D
My friend Hyperhorn is at 17m13.985s and I'd like to beat his score, but he believes sub 17m10s is possible, so that might be the new goal. :)
Damn you man, you are making me want to haul out my mobo lol. I don't have a PSU or a HDD I can use either so I'd have to make a quick order. Must resist.
I have no idea how SPI32M is so much fun. To a casual observer anyone running that bench must look completely insane, staring into space, mentally extrapolating from each loop time what the final time will be, willing it to run that bit faster each loop. We're all nuts.
Are any of you Gentlemen brave enough to try out some 8GB kits with 2x4GB?
Apparently G.skill Sniper CL7 Kits are pretty good, however I have not seen very many results on this board to make a decision to purchase.
John
@CryptiK: Please be careful mate, I don't want you to fight over the REX with your GF! :D
LCCs are great fun, but incredibly time consuming, I still haven't got any good results for the 3 and 4GHz categories at PCGHX, only 2.4, 3.6 and 4.5GHz. The first two categories can both be done at 500MHz FSB speed, which means I'll have to tune memory timings once again... :rolleyes: :D
While I was at it for the 2.4GHz category I also tried to make a 17m59s score, but the board refused to boot at lower FSB speeds with the settings I used for the 32M run. Very weird behavior...
@JohnZS: Sorry John, I don't plan on purchasing a kit and I guess running them on the board, especially with an overclocked quad core processor, will be very tough.
Its ok, she's been upgraded to the R2E & Gem 920, the REX is now in the cupboard ;) Ah ok, I have only seen the LCC here, where its time categories not CPU speed categories. They are a lot of fun though.
hope its ok to post this here. I have been looking for a mod bios for the RE that has newer Intel Option Rom. I finally found one.
http://www.megaupload.com/?d=YC13RW9R Its from what i can see its the newest beta bios with newer option rom
"Intel ICH9R 9.6.0.1014 "
Been using this a bit. All seems fine.
Has a few other mods. Not sure what they mean. Source. http://www.jmax-hardware.com/forum/i...ic,6246.0.html
Sorry to resurrect an old thread but my issue still seems relevant to others and I'm hoping to finally find a solution. I've run a REX/QX9650 for 3 years, custom built, liquid cooled system. It's all set to AUTO *shame* but every so often I tinker with the BIOS to see if I can hit the 24/7 settings I want;Quote:

That's it, that's all I want! Problem seems to be that I run 4x2GB sticks. Yeah, I know. Ramguy over at Corsair swears it can be done, he just hasn't ever explained HOW! lol
After reading through hundreds of threads, I've come close to getting stable but I still haven't any idea what voltages to use for RAM and things like AI Twist in the BIOS are a mystery to me.
This is the RAM I run, it's DDR3/1600 but obviously running on AUTO dumbs it down, quite a bit;
Corsair XMS3 DHX CM3X2G1600C9DHX 2GB (X4)
DDR3-1066 DDR3 SDRAM (7-7-7-20 @ 533 MHz) (6-6-6-18 @ 457 MHz)
Once and for all, I'd like to nail this and get it stable. I'm sure one of the OC Masters has some input and it would be GREATLY appreciated. FYI my algebra sucks.
EDIT: FYI, the temps on my dual loop with Swiftech block are chilly, 21-25c on idle, 35-39c on stress. NB is hotter by 15-20c.
8GB is going to be tougher than normal, but if you dont aim too high for ram speed ie: DDR3-1600MHz, you *should* be able to do it with the proviso that your CPU can do 4GHz at reasonable vcore.
I cannot remember what a reasonable vcore for 4GHz would be, but that can come later. First, you need to get it stable at 400 FSB and DDR3-1600MHz. Start with PL10, loose ram timings (set primary timings to 9-9-9-24 and leave the rest on auto for now) and set the ram's designated voltage for its rated speed (will say this on the ram). Set vNB to 1.45v, set Vtt to 1.30v. Set AI Clock twister to moderate (this setting controls chipset subtimings and directly affects memory subsystem bandwidth and latency). Leave clock skews on auto for now, they shouldnt need tweaking at these settings unless 8GB affects skews more than I think it will.
Now set your FSB to 400 MHz and set the strap to 333 (you will be using the 2:1 memory divider so setting 400 FSB will give you 800MHz (DDR3-1600MHz). Set the CPU multiplier to 8x (this will give you 3.2GHz CPU).
Try that and tell me if it boots and gets into windows. If so can you run some prime large FFT's for 30mins or so.
Thank you, CryptiK. I'll set that up this evening and post back. Would it be easier for you to use a template?
8 gigs is tough
i was only able to overclock mine to around 1900 but with a dually
even 2x2 was tough to get a q9650 higher than 475fsb with 2x1 500fsb was doable
quads +2+gb stix dont play too nice unless you got nice chips
Yeah it probably would I was chopping up stuff for dinner and just writing as I though of it :p:Quote:

On a lighter note, I replaced my horrid ram with good quality Corsair RAM which is very happy @ 1.50V CL8-8-8-24 and NB @ 1.27V
I admit I epic failed with my overclocking attempts. Perhaps my QX9650 was a bad chip? or I am pretty crap at this tweaking. Either way I am reasonably happy with 3.33Ghz @ 1.27V (core), 1.20V (FSB Vtt) and 1.51V (CPU PLL).
Any higher and the system loses stability and/or requires way too much volts. For example 10.5 multi (3.5Ghz) requires 1.32 V on the VCore and 1.31V on the NB
That is a big jump in volts for a small increase in Mhz.
If I am honest I would love to have 3.66Ghz stable, but it is just not possible :( Or at least I do not know how to tweak without hitting notorious BSOD when LinXing. (causing disk errors) if there was a USB bootable Prime95/LinX that would be ace as I could happily tweak skews and GTL (currently using 0/2 = AUTO and 1/3 = +40mV) until I find stability.
John
guys,i just wonder what other block can fits on rex since the bitspower full coverage aix48 already discontinued and and no longer available at my country.
just wanna complete the unfinished watercooled project on my rex. :)
So I'm settling down again to try to OC this board. Running a QX9770 with 4x2GB Diablo RAM. It's pretty nice. Requires a lot of voltage, though. I dropped my multi to 6 in an attempt to get the RAM stable at 1800 (450 FSB), with an aim to 2000 eventually. I'm at 2V on the RAM (only rated for 1.9 but oh well) and 1.55 on the NB. It's WC'd so we'll see how far I can push it. Anyone know what's the highest I should be shoving into my NB for 24/7 usage? Temps are fine.Quote:

Seriously all my gear is still in pristine never degraded condition when I sell it so you can take my max as a baseline. I know that short runs at 1.85-1.90v on air has degraded some NB's so not advisable going that high daily.
you got a block on your nb or you using the heastpipe+ block
i ran nb 1.63v watercooled forever n my nb never hit 35c
as long as your temps are good ....:up:
its heat that degrades the nb n goin over 1,7v
i also have enzotech copper heatinks on pwm
i doubt you gonna hit 1900mhz
its tough hittin 2000mhz with 2x2 lol n you wanna do 4x2b with a quad
Hallo
I am very new here and what to ask some questions to OC Expertes here. I have a Rampage Extreme here which is watercooled by Liquid Extasy Fullcover cooler. At the moment i have an E7200 M0 CPU which i OCed to 3,8 Ghz @ 1,35 V.
At the start i want to know what are good temps for Watercooled Chipset Nb and SB. At the moment i have NB 35°C and SB 36°C under load (Prime95 8 hours) Is that ok?
In the Future there is an incoming QX9770 CPU. The Final goal is to reach a stable 24/7 Setup. Minimum should be 4 Ghz. 4,5 Ghz is the final goal. But somethere between 4-4,5 Ghz would be ok. The other thing is i want to have 8 GB RAM. This is the cause i desided to get a MB Watercooler because all i red the vNB must be very high to get 8 GB working with Quads.
I suppose so it will be hard to get this under water and low voltages for 24/7. But we will see what comes in the future.
i also have nb watercooler and @ 1.63v i never pass 35c
nb wont degrade as long as it runs cool so you can pump up voltage;)
you should be able to do 4.5 if your cpu can do it "because of unlocked multi"
hope you didnt pay too much for that cpu
Hm thx for reply. Hm, what type of Watercooler u use at your Rampage Extreme x48?
This is mine:
http://img406.imageshack.us/img406/3...030710u.th.jpg
I dont think it will be so easy to hit 4,5 Ghz with that CPU and 24/7 longife Voltages. I read several topics about this CPU and found it depends mainly on luck-factor what CPU you get. The only thing i could do was selecting a C1 Stepping with the latest Batch number i could found.. I will see what CPUID it will have.
My personal limit for 24/7 is max 1,35 - 1,4 V Vcore and max 65°C under Load.
It will be realy hard and lucky to reach this.
honestly your better of with a E0 9550 than anything c1
i use a moded swiftech nb wb +enzotech copper pwn heatsinks
my has been in a box for a while now lol
If you guys are looking for a modded BIOS with updated RAID rom:
http://www.ocztechnologyforum.com/fo...-10R-RAID-ROMs
Anyone have any luck with 2x8GB sticks. Just grabbed the Geil EVO CORSA 1333's. they do not post. don't get used but will show up in cpuz etc.
Any bios that worked for 2x4GB?
Tried 0404 / 1305 so far.
not sure what prevents them from working, given they're the same rank and banks as my 2GB sticks.
done 2x4gbQuote:

rex dont like cheap ram ;)
You might have reached the limits of X48, here's a small excerpt from the X48 datasheet, page 19:
• Supports 512-Mb and 1-Gb DDR3 DRAM technologies for x8 and x16 devices.
• Using 512 Mb device technologies, the smallest memory capacity possible is
256 MB, assuming Single Channel Mode with a single x16 single sided un-buffered
non-ECC DIMM memory configuration.
• Using 1 Gb device technologies, the largest memory capacity possible is 8 GB,
assuming Dual Channel Mode with four x8 double sided un-buffered non-ECC or
ECC DIMM memory configurations. Note: The ability to support greater than the
largest memory capacity is subject to availability of higher density memory
devices.
2Gb ICs might still be okay but 4Gb ICs might just be too much for the memory controller to handle.
i'll test a cheap 8gb once it arrives.
these x48s are so sweet to have :)
-one dead rex
-one dead p5e3 lol

LOL you just reminded me I still have my REX. I totally forgot about it :rolleyes:
thanks everyone. if there is some trick to get 8GB sticks working on this board i will be excited. otherwise i have to upgrade. but i just love my rex so much.
I personally think 4GB sticks would be pushing it as officially X48 maximum memory per DIMM slot was 2GB , however P45 expanded this to 4GB per slot and along came some speculation that this also meant X48 supported 4GB per slot too, just at the time the boards were ratified,, by Intel, ASUS, etc 4GB modules did not exist or were not available so they did not test the X48 with 4GB DIMM's , hence no official support
I have read that quite a few people have had mixed luck with 4GB DIMM's, some can run 8GB (2x4GB), others have even managed to get 12GB working (3x4GB), however the magical 16GB seems VERY DIFFICULT to obtain stability with on X48 and you can forget about Overclocking with it :(
John
Still daily running X48 with QX9650@4ghz at 400FSB and 8gb rams (2 x 4gb) at 1600mhz and ATI 5870 at my parents... 8Gb dimms might be pushing it
my 8gb stick doesn't work... fyi
what stick do u used?Quote:

John
does u try out on 2000mhz?
Nope, I have 8GB and I admit that even 1600Mhz is not stable as I am running a Quad, but I can get close to stability, however am wary of frying things due to the voltages required to stabilise the NB and it IS running at high temperatures! (due to the stress of 8GB)
I think 2000Mhz would only be stable on this board with a decent Dual Core and 2GB of RAM (1GB per channel)

Hello Guys.
Old good Topics never die...
I am upgrading my old but mighty Rampage Extreme X48 Rig with 8 Gb of RAM with big fear of losing my QX9770 high FSB. My Rig can be seen here.
Finally i upgraded from CMX4GX3M2B2000C9 2x2 GB Kit to CMX8GX3M2A2000C9 8Gb Kit 2x4GB Corsair DDR3 2000 Cl 9-10-9. What i should say, it runs very stable at 450 Mhz FSB and 1:2 900 Mhz mem Speed CL 9 9 9 24 88.
http://img707.imageshack.us/img707/1251/yyp.png
After that success i become greedy and tried 12 GB setup with 2x2 + 2x4 GB Rams. It didn?t work at 450 Mhz FSB. But at Stock FSB Speeds (400 FSB) and with 5:4 divider (533 MHZ) System boots and should work. But since 12 GB of Ram is not needed i stay at 8 Gb Rams and sell the 4 GB Kit. My next goal is to get some better 2x4 GB Ram Kit which runs at 1800 Mhz and Cl8 Timings. Just because the Core 2 Generation is the last Generation before the Integrated Memory Controller Stuff that can take advantage of low Latency.
After that the next step is to get two GTX580s and try out if the HyperSli Mod will enable some Power on my bold 775 Rig. We will see....
