XP 64 bit is smoking fast when you fine tune the OS and services. Vista is "ok" when it's tuned but that statement is pretty crazy in my eyes. :rofl:
I have my xp64 tweaked out and have the same video as you and I've got 3259mb free and utilizing 20%. What happens when you right click on my computer and select properties... does it say you have 4 gigs installed and the OS is seeing it?
I get the following:
Windows XP

I think I'm just going to re-install windows again and see if that helps any because I am at a total loss as to what would cause this....
Wow, that sucks ... I'd never know where to begin, but it does sound like a memory mapping issue within XP ... out of curiosity, does the system properties page change when you take out a stick at a time?
I can't tell from your fuzzy screenshot but it looks like Everest is reporting 2046 for system RAM? Have you tried stock speeds for your cpu / mb / ram? What about moving the modules to diff dimm slots to test as well? Try 2 at a time to see if one set is good or bad.

Too late, I'm already in the process of re-installing windows so I can't check that right now. If it happens after the re-install I will start pulling RAM to see what happens
Windows was reporting 2.75GB and Everest reported 2.xxxGB of RAM but CPUz and Everest both reported that I had 4-1GB sticks installed. Also, everything is still stock. I haven't had the chance to OC yet. As far as the DIMMs themselves are concerned I tested both the Mushkins and Patriots for several hours each using MemTest last weekend and they both came through w/o any errors
I definitely think its a memory mapping problem. I know the Asus Maximus Formula has a section where you can enable/disable memory mapping but I couldn't find anything in the DFI BIOS that was related to memory mapping. Oh well, I guess I'll find out in about 30 minutes.....
huh.....all appears to be well on the western front.
Well, it appears that my problem stems from Everest version 4.50. Windows was reporting 4 gigs of RAM up until I installed Everest at which time Windows went back to reporting 2.75GB. For some reason it is passing incorrect info to the OS.
I sent them an e-mail so hopefully they'll sent me an update soon.
what's this????? :confused:
http://img127.imageshack.us/img127/2...gineov0.th.jpg
i have last bios and last cpu-z my system is tested 10 hrs occt 10 hrs prime is stable...at default clock same issues :S
ps another strange issue why after 7hrs of occt my vcore increases? from 1.408 to 1.420? for 7hrs is at 1.408 stable... i have vcore drop control disable
Then your prayers have been answered:
http://www.youp-pax.org/viewthread.p...a=page%3D1
XP 64 bit drivers with all the bells and whistles from the Vista only packs that creative release, diagnostic utils, speaker setup, and a TON of improvements over the creative drivers. I installed these and they're a notch above how my system sounded in Vista 64.
You can also install all the programs in XP from the original CD then use the auto update agent to update them even thou the drivers and software for xp 64 bit are not on creatives site. Base driver support is offered but not EAX or the console... they're pretty damn sneaky these days.
hi guys...i need help badly...
i can't bring my 45nm quad x3350 on dfi X48 mobo above 420 fsb.
i even lower the multi to 6 , 450 x 6 = 2.7ghz. and the setup can't even boot from bios. i tried to up the NB volt to 1.45v , it was the same result.
what are the possible reasons that caused such limit?
thanks
im suprised this thread isn't bigger and the maximus formula thread is 200 + pages long
the dfi is miles better in terms of stability..
with 8gb of ram , this board really shines in vista 64
i got the 2x 4gb kit reaper 1066
i can't run them with just changing the divider and upping the nb voltage to 1.35
should I wait for the new bios or try anything else?
Im after some advice please as ive read through the post`s and am i right in thinking that for the 45nm E8400 that the max FSB vtt is 1.45 so 1,4 or lower is better ? and what about the v-core as people seem to be getting 4Ghz on 1.36v or so but what is the max safe volt for it.
Ive just got one so im gonna oc it over the wk end and see what i can get out of it so any other advice is welcome.
Cheers All!!!
Edit.. Have i got confused is 1.45v the max v-core and the FBS vtt can be as low as 1.2v??? HELP !!!!!
Well here is my 1st boot up with it in with gtl settings @
1/2 95
0/3 90
nb 75
http://i249.photobucket.com/albums/g...untitled-3.jpg
Im gonna occt now and see if im stable @ 3.96Ghz...... fingers crossed.....
You did have it turned around in the beggining of this. 1.45V is the Absolute most as says Intel for V-Core
I'll have to read thru the pdf again if I can find it, but I thought VTT shouldn't be higher than 1.15V for the Dual Core 45nm, could be mistaken on that, but for 4 gigs with an E8400 you surely do not need high VTT.
Larry
Well its been done 2h stable with the following settings...:up:
http://i249.photobucket.com/albums/gg211/wils07/1-1.jpg
http://i249.photobucket.com/albums/gg211/wils07/2.jpg
I think i will stick with 3.917Ghz for now as 4Ghz gave me errors after 5min of occt.
eh...
try this
reduce ure vtt back to 1.1
change ure nb gtl to 60
cpu 1/3 to 90
cpu 0/2 to 85
nb voltage at 1.4 since ure running 4 sticks
enable vdroop control
then just adjust vcore until occt passes..
445 bus on 45nm's c2d vtt at stock is still okay..
clunk do u know when dfi x48-t3R is coming out??
going to ddr3 ..
anyone with 45nm quad , can you go above 420 FSB?
anyone???
thanks
thought this might be usefull for 45mn
All these GTL charts are great but what are our GTLs supposed to be? I understand that all boards and CPUs are slightly different but a good starting point would be fantastic. I've been all over the spectrum from 75-120 on my GTLs and i've been stable for a period of time in P95 in the whole range. I've upped my CPU VTT and Vcore to points that I think "should" work and then try adjusting the GTLs to dial it in but there seems to be no rhyme or reason for failure if I go up or down.
Axis
I had a really hard time getting my chip stable at 4ghz but after doing some numbers using the anandtech's chart for 1.16v for vtt i got it rock solid now.
Are you using the quad that's in your signature? There is a chart on anandtech, somewhere, that has VTT settings for quads that is a guideline for how much vtt to apply at a given FSB. You could probably find that and then get a good idea what your VTT should be in range wise then dial in your GTLs per the chart as well.
I just have a quick question.
When i start up my pc it powers on for about 4 seconds with nothing coming up on the screen. Then it turens off and powers on again about 2 seconds later. Is this normal? I am just worried i have changed something in the BIOS that i wasn't supposed to.
Thanks
that chart is for 45nm
every board every cpu is different you gotta test gtl settings
if you dont wanna put in the time to do so get an asus board
for 45nm its 61-63% for 65nm its 66-69%
gtl settings have to relate to each other by % +-1
you can alse go auto till you reach the max then you need to set them manually
some people have got upto 485fsb with auto i couldnt go past 440fsb on auto
gtl settings have to relate to the % +-1
dual cores are forgiving with quads you gotta be more precise
when i get my board back first thing i will do is measure all voltages n gtl voltages
lol 2 hours not even after 2 months
yes i found my 24/7 long ago just lookin to make it better
you can set gtls to auto till you hit the wall then you gotta find the setting that will get you to the other side
setting the right gtl setting @ any speed manually will get you more stable
asus board is like driving atomatic tranny dfi like a stickshift
mind you i seen better performance on the asus
dfi gotta get its bios on track
I had to disable GTL to get stable but when i had a lower vtt i got crashes as with a nb volt of 1.4 but this could of been because i had GTL enabled with bad settings maybe.
It was late when i finished last night and was just glad to pass @ 3.917Ghz but 4Ghz is my goal.
Is anybody using GTL enabled with 1.16 or lower vtt and if so what settings have you got as cstkl1 & zsamz_ have given some answers but both are different values and with it needing to be disabled to pass its gotta be related .
any tests and temps with the UT version?
As previously mentioned I had problems getting 4Ghz stable but went up in VTT to 1.16v and used 82,79,63 (straight off the anand chart for 63%) and i've been stable since.
If your GTLs are way off you won't be able to boot usually.
I suggest having pen & paper and a boatload of time on your hands :rofl:
@Pnot
I will try it and see if it helps ,also can you tell me what your nb and v-core is pls as we both seem to need the same vtt.
Cheers Paul
update
Ive just tried them with 4.0Ghz and got a code 4 2mins in i also got it with GTL disabled? Colud it be my vcore needing 1.38 insted of 1.36 but it seems high for a 4.0 Ghz oc.
hmm best way to eliminate ram and nb gtl/voltage and vtt
is by setting it in bios
and run WDMT or memtest86
until that is stable than only use occt
keep upping the vcore until u find stable with minor adjustments on cpu gtl.
i find this is the best way to clock on this board.
Thats not accurate at all. If a person does not keep the system on a ups, unplugs the computer, or loses power, the system does the reboot to reset the registers every time on a cold boot. Not caused by a bad clock at all.
This would be accurate were it a reboot, or the board never lost power.
Larry
Can anyone tell me what happens when the GTL are disabled? what is the default setting`s if any.
ah thanks mate u just worked something out for me . im memtest /occt 2hrs stable and prime.
but sometimes i have to turn pwr of at psu and pp, to drill holes, mod etc
then it reboots a cple of times when i start . i was thinking it still wasnt 100% stable, but now im sure it is. :up: thanks.
Eh, I'm a lazy OCer, but my last ASUS mobo left a bad taste, so I came back to DFI. :)
It's amazing what a wall you hit at that FSB 420 spot. I was trying to get it stable at 425 and was still having problems with being stable for longer than 5 minutes in Prime 95 (I still had voltage room to play with, but I like to be conservative). I knocked back the FSB to 420, and I keep finding I can keep knocking the CPU and VTT voltage back more and more and still not get any P95 errors. Funny how big a difference that 5 Mhz is.
E8500
X48 LT
ballistix 8500x2
9800GX2
PC power&Cooling 1200w
i tried reducing vcore to 1.45 but lost stability so i had to increase it back to 1.47 wont go lower
i did manage to reduce vtt to 1.310 120/110/90 and it didnt effect stability
i will try lowering vnb down to 1.5 but i doubt it will work .
i did have it at 500fsb 4ghz stable but it required over 1.5 vcore and over 1.6 vnb its not worth it at those volts
i might have to get one of those e8400s everyones using, they dont require as much volts as this x6800.

*soz about the image size i cant work out how to post it in a large format .i tried everything lol wilson how did u do it?
I have read much of what you writing here .... and with a few hours lost my system to get 100% estable!!
I think many people going to use nbv very high in relation to mine:)
http://macavenco.no.sapo.pt/8400.JPG
you vcore not high that @ 1,5v for 65nm i can run more than that no problems
play with your gtls settings margin for error verry small @ high fsb
you need 1.5 nbv for 500 fbs
n running 4 sticks tougher on the board
i can run 505fsb with 4 sticks but i need 1,6nbv 1220 5-5-5-15 2.1v
yeah i should be satisfied and i kind of am . but i did expect more than this. i thought at 475/1141 3.8ghz apps games pics etc would be superfast but there not , even though i have 4gb installed with vista its still pretty much the same. a page of photos still has to load its not instant etc same with apps there not that much faster.
if i went over 4ghz ,would that make much of a difference ? ie- loading /running games ,maps , apps ,photos, etc?
I'm at 4Ghz with my E8400, 4 gigs of RAM, and used to have Vista 64 but running XP 64 now. My apps and photos, from my camera, run super quick. My boot times and how fast programs load on startup are amazing compared to what they were.
Is windows reporting that it's seeing all 4 gigs of RAM? What are you RAM timings because that has a lot to do with things as well. Defrag your disks if you haven't already done so.
3.8 -> 4 ... I highly doubt you'll notice much of a difference.
Does anyone think by dropping my multi from 9 down to 8 it will help get me to 4.Ghz.
Or do you think i need more vtt as ive tried more v-core , more nbv and GTL enabled and disabled and different ram settings and i always get code 4 about 2 mins in. All i have left is to raise the vtt but is there a limit as to how much i should use ??
It's easier to use 9 to get to 4ghz because your FSB is at 445 instead of 500. 500 FSB takes more VTT, RAM is more picky if you don't chose the right divider, and the NB is under more of a load.
As for the VTT limit i've read at numerous places you do not want to exceed 1.4-1.45v.
This pic i got from one of anandtech's articles but i can't remember which one so i'll post it up here:

adya.. thats a good proc
not many x6800 can do 500fsb

the best i can do for 1000 mhz CL4
http://i287.photobucket.com/albums/l...Untitled-1.jpg
you gotta find the sweetspot
run everest n spi to see what is best
cmmon man crank it up to 505fsb n see
even 455fsb is ok
your cpu can do 4.0 no sweat
makes no sense to get a e8400 over your cpu bot really an upgrade
me i'm holding out to see whats commin out thinkin of e8650+
I haven't tried running 400FSB to see if my sticks will do tRD 6. I'm doing CL5 atm at 445 with no problem. My everest scores are pretty good but not mind blowing. I think there is still more work on my end to find a good spot for these. I know that Raja, from anandtech, who reviewed the DFI board said that the new bios options let you play with the skew rates and it makes a world of difference. I wanna get my hands on that bios already =p
I had Orthos sometimes fail after 6-8hrs of testing so i can't say that 2hrs is enough in OCCT since i haven't run that app much. I had major stuttering in Vista 64 bit that nothing fixed for some odd reason. I went through diff driver versions, mouse drivers, usb polling speeds, defrags, and a ton of other things to try and figure it out and nothing worked. I finally said screw vista and went XP 64 bit and i have ZERO stuttering period. I did have to up my NB a notch but that's about it.
I can't say for sure that Vista was my problem but going directly to a new OS and my games are SILKY smooth now with my 9800GX2 and deathadder... i'll stick with xp :)
man i just lost my oc and had to reset cmos again! than god (or atleast dfi) for cmos reloaded ! what a life saver that program is !:up:
i just wanted to reduce trc ,its at 53 . my timings are 5 5 5 15 trc53 .
with my oc as seen in my sig , with 4x1gb, should i be trying to reduce trc to say 30? 53 seems abit loose , but im not sure since having 4 gb changes everything. anyone with 4gb have theres lower than that?
*i was just reading that the formula for trc is -trc=tras+trp so for me it would be 15(tras)+(trp)5=(trc)20 . but ive tried 30 trc and it just crashes. any ideas as to how could i set my mem timings? im following the formulas but they havnt been very succesful. i think my timings are the reason my system is still running slow .
im possibly thinking of ditching my evga 780i for this board. This thread is so long could someone just tell me very quickly the differences in the LT and UT other than price? All it looks like to me is different stock heatpipes.
@hoodlikegaza
yup you got that right. its with the cooling solution.
This Board overvolts bigtime compared to the P35. Is this an added feature of the X48 or is it just happening with my board and the settings that I have. Also if over volting is not a feature then could someone explain to me why it is happening. Eg set 1.2375v in Bios, shows up as 1.248v Load CPUz. Vdroop enabled.
Yes this board does overvolt alot. Make sure you have cpu special add turned onto .23%, auto overvolts your cpu volts more
I guess i'm sloshed as well cause my board overvolts too. I have Vcore 1.306 with special add 100.23% and get 1.34v as indicated in SG and Everest. It does Vdroop to 1.32 under load since I have it enabled. I'm running the official 0320 bios. I just use the bios setting as a trending setting. If I need more I go up, then check SG and Everest to see what it really is.
Axis
special add will not be precise
maybe i was just so lucky with my board till it messed blew lol
hey maybe i get lucky n i goto 600fsb on the next 1:ROTF:
but on every settin it undervolted by 0.01v
oops i messed up on nb volt it undervolted by 0.05 with x48 bios it undervolted nb by 0.02v
btw everest is not 100% accurate chek with dmm n see
Well, I will give it a try with Special Add NOT set to AUTO and see if this might rectify the Over Voltage. One more question for you guys about CLUNK'S GTL Ref Tables, and by the way Clunk thanks for all the effort in setting up this guide Post. I still DO NOT understand if there is a relationship between the CPU VTT and the NB VTT or if there is any.
For example if I use the values of 110 (GTL 1/2 Ref) 105 (GTL 0/3 Ref) and 85 (NB GTL Ref) from Clunks Table for 1.2500v CPU VTT BIOS Setting, what should the Voltage be for the NB VCore in the BIOS, can that be anything I set it to for example 1.405v.
The reason I ask is that P95 failed after 9.5h it fell over executing the 4096K FFT, so I figured I would focus on the NorthBridge
I can understand a little variance but we're talking the difference between 100.24% and 102.6%. Like I said, i'm not pissed about it. It's just that i've never been able to fully trust the Vcore settings. The rest of them seem to be pretty spot on though.
Wasn't your board a X38 flashed with the X48 bios? If so, that could be the reason you're board behaved differently.
Axis
Well They have blocked the Special Add Option and I cannot use it unless I set the VCORE to >1.3000v. This really SUCKS, so I guess I cannot fine tune the voltage I need unless I run at a speed that requires more than 1.3000v.
Oh I did read the reason why as explained to Clunk by DFI.
http://img170.imageshack.us/img170/9241/imagemb5.jpg
this mosfet sec gets REALLY HOT! I can barely keep my fingers on it for more then a couple of seconds
anybody come up with a cooling solution for it? or do I just have to make a custom sink?
@wilson
good job, are those 2x 40mm strapped together?
Yes but i also found that a old evga 680i nb fan did the same job .

Took me a while to get around to OC my chip w/ this board due to work but I finally got my basic OC finished. OC is stable 5 hours Prime Blend and 7 hours small FFT's. Further memory testing done using memtest w/ 3 instances running simultaneously for ~1.5 hours @ a time. Here are my settings:

Other thoughts. Using the 2x2GB sticks must be less stressful on the NB than populating all 4 DIMM slots because 1.29V on the NB is far less than the 1.55-1.58V my Maximus required to run 4x1GB sticks of PC-9200 Mushkin @ 1067MHz 5-5-4-12-30.
I've got to hand it to the DFI guys, they definitely put together a well thoughtout and stable BIOS. I only had to clear the CMOS once and that's when I started messing around with fine delay settings. Other than that it was clear sailing the whole way to 3.8GHz.
I'm using one of those Antec Spot Coolers bent over and blowing on the PWM, I've got it plugged into the system fan plug so that I can control the speed of it via software, but it also has a 3-speed switch on it.
here ya go
i just my board back and i gotta say its much better than my last one so far
pic of mosfet with sink from accelero s1 i had to cut it was too long it was made for ati card stuk it with thermal tape + a screw
i had to lap my pwm sink too was bad i added those pics too
man :up: that is power and beauty :p:
