As above, no I haven't - don't have any spares. I agree, this definitely needs to be done to be sure - was just checking to see if anyone could perhaps point out something obviously wrong with my OC attempts, or rule out CPU.Quote:

Haven't tried running with two sticks - but if it doesn't work with one, why would it work with two? Regardless, I'll give it a shot.
Current BIOS is the latest non-beta from the DFI website.
I was mistaken - it's a C0. I always knew it was the old revision, just wasn't sure what was what.
Okay, here's my cf or 88 clear procedure. I have to do this often on this board but it absolutely works.Quote:

Board will cycle CF first, hold then C1 the a couple things before c26. If powers off after c26 then just unplug again but skip clear cmos. After 26 you'll get beep and all will be fine.
Do this with two sticks of ram. Because you have a C0 chances are the memory controller may be weak and struggling with 6GB of ram. Your bios is okay for your hardware but your board is definetly behaving as though there's a memory issue. Makes me wonder if you do have elpidas under those spreaders. Which would work better with 4/28 regardless of C0 or D0.
Not necessarily. Some of the UT boards will not overclock with either the 04/28 or 05/08 BIOS. Which is why the 02/17 is used as a base for internal troubleshooting. Although this does not seem BIOS related as the symptoms are different.Quote:

That's what I was doing above for "cold reboot" - and as you say, it no longer hangs on CF, but instead goes to 26, but at 26 the board reboots and goes back to hanging on CF again.Quote:

But, why are you so certain it's RAM related? Not that I don't appreciate the suggestions, I just don't understand why if my board can push these three sticks to a full 1850 CAS-9 using 185 BCLK and 10x memory multi, you'd then think that the RAM is preventing it from booting at 190 BCLK with memory multi of 8x for 1520 and CAS-10.
My board performed well with the 2/17 bios until I switched to elipdas. I had to use a 3/18 bios to get those to work well this was on c0. When I grabbed a D0 I flashed to 5/08 and it was horrible. I flashed back to 2/17 but couldn't get much over 210 BCLK so I flashed to 4/28 and have had no issues with elpida or samsung hcfo's. I run corsair dominator 1866's for 24/7 settings and they never gave me any trouble they they like higher voltages. I still think 4/28 is best for elipidas once you start raising the blck but thats just my expirence.Quote:

Have you tried by using live tools like setFSB to try 185 bclk instead of cold boot?Quote:

Any of you guys experience this issue? I have this problem both on my W3520 and i7 920 D0...it should be a mobo issue isn't it? :shrug:
Haven't tried anything like that, no. I got burned badly on an older version where using SetFSB corrupted my OS and borked the board, haven't tried since. I'll give that a shot.Quote:

Stable as anything and cold-boots fine from then on after that, though.
Post code 26 reboot is most common with the D0 processors and the 04/28 and 05/08 BIOS. The IMC is attempting to sync up with the memory channels. I've seen the board take as many as 9 reboots before being successful.Quote:

I have been playing with this board for a couple of days now and have been stumbling across a few issues:
I have a D0 920, Elpida BBSE 2000 G.skill Tridents and am using the 05/08 bios...
1: I am getting a lot of lockups on CF and then lots of reboots and recycling back to CF from code 26.... if I make it past 26 then everything is fine... (quite often it is 3 or 4 cycles - cheers for the info Praz)...11 cycles? :eek:
2: I am getting a weird CPU fan issue where the fan spins up to max from its nominal value for 5-10 seconds and then returns to nominal value. This is happening every 5 mins or so and the rig is currently just sitting on the desktop idling. The CPU fan thresholds have been set but when it spins up to max it is not anywhere near any of these thresholds...
3: I have the same BCLK issue as SoulsCollective except my ceiling is @ 200. I can run many other configs ok but if I try 201x20 I get a non bootable system even when 200x20 ddr3 2000 + turbo x21 & x22 is fine dandy and rock stable. I have tried 1 stick and 2 sticks and if the ram timings got any more relaxed.... ;) Could this be some kind of strap issue like we had with some 775 boards? Ie just a tiny increment takes us over a threshold which changes the timing of something else unknown and causes a non boot situation?
Have you tried higher then 201? Might be a dead spot. My board will not boot at 198 regardless of settings. 197 and 199 are fine.Quote:

Ugh.... so I got my T3EH8 today... plugged it in, got a stop code of CF which I determined to be caused by my placing the RAM in the yellow DIMMs instead of green due to a voltage difference?
Anyways.... I get that done I get a CF code again but it immediately kicks to a Code 88 and I get an acidy smell like something bad happened, I take EVERYTHING out and look over the board for any signs of damage or what could have caused that smell... it checks out fine so I reinstall everything and try clearing CMOS as I had seen in a few threads concerning CF/88 Code.
Long story short..... I gotta wait for Newegg to replace this board before I can join in on this thread :mad:
want to point out some cpu issues that my friend tested on the classy
he got two procs of 950 D0 3844A920
one couldnt do bclk 200,, was stuck at 190.
the other could
also after 4.4ghz on bclk 200 to do 4.6ghz dram 1600 he had to up his vtt the same amount as his vcore
so 4.4ghz 1600mhz bclk 200 vtt is 1.2
4.6ghz 1600mhz bclk 200 vtt is 1.4
maybe the acid smell was the paint job?
you'll get that if cpu vtt and vdimm aren't set optimally - i experienced this on 4/28 beta which is what 05/08 beta is based on - posted a note on this in post #20 and #21 at http://i4memory.com/f80/4-28-beta-bi...8-t3eh8-17224/Quote:
Originally Posted by Biker

remember voltages you used for 2/27 and early bioses might not be same needed for 4/28 and 05/08 beta and i suppose the official 05/08 bioses.
As per tip #30 at http://i4memory.com/102537-post3.html (list of links in first post of this thread) - memory modules in single, dual and triple channel need to be inserted in correct dimm slots, single or dual channel need to be in dimm 2+4 only for most X58 boards. Triple channel with 3 modules is 2+4+6 dimm slots only.Quote:

- For single and dual channel use dimm slots 2+4. Seems you can also use dimm slot 6 for single channel as well.
- For 3 module triple channel, dimm slots 2+4+6
- For 6 module triple channel, populate all dimm slots
woah stuck at 190/200 bclk is low and batch is only 1 or 2 weeks before the week 45/46 gem batches too! sounds like your friend got a type 4 i7 cpuQuote:

http://www.dfi.com.tw/portal/CM/cmpr...rue&itemId=561
Like most of the ABS files the voltages are quite a bit higher then most of us use. VTT is set to 1.50V. My board will boot into Windows at that setting but will not pass any stability tests. 1.36V - 1.42V will probably be where most users will end up, assuming an average D0 CPU. After finding the optimal VTT voltage the other voltages can be adjusted while fine tuning VTT.
Boot UP Clock is set to 135. Can try 130 - 160 with 135 - 145 being optimal for most setups.
There will be a BIOS released based on the 05/08 that addresses these issues.
Cheers guys .. gotta wait 2 weeks for this baby to get it @ my place , but i guess i ll wait now :)
Play around to find a sweet spot, and 19x seams to require less Vcore than 20x, just like my good old i7 920 CO., But i couldn't dream av primestability at BCLK 220 with C0.
VVT: 1.24/1.28v (BIOS/Load)
NB Core: 1.13/1.12v
w3520 @4.18GHZ(220 x19), 1.2v , 1 hour primestable
http://img189.imageshack.us/img189/6...ft1hour.th.jpg
I have to test more before i go further with this setup. I don't know how my GTX 295 would react to BCLK 220. So far so good and if this setup "behaves", i may use this for 24/7.
What the hell is this?!
http://i317.photobucket.com/albums/m...8/P1070092.jpg
I cannot even get the boards power buttons to turn the board off after I had that acid smell + code 88.... it requires that I cut the power the PSU.Quote:

Edit: no matter what I do... Clear cmos or any combination of memory in dimm, it simply will not boot. It sticks at code 88 and I get no further.
Is an acid smell normal on dfi when starting it up? I haven't used a dfi since the RD600 days.
Vcore i think, i use my UD4P board now...but after what i remember that is vcore.Quote:

Nothing unusual about that at all really. All mobo's tend to react in the same way when changing GPU's. Even more so when changing to a more powerfull GPU then was installed before.Quote:

Still not booting, so maybe Vista is shot. Started reinstalling and guess what, it seems my raptor can't be found using AHCI mode anymore, IDE is fine and I've got a working install again. Didn't try another hd. Any ideas, did I just shoot my controller or HDD?
I have been running @4.01GHZ(19x211) for 24/7 use on both i7 CO, and w3520 and never had any problems. I have had a few short (10-20) Linx run with SSD on SCSI-mode too.
I have got a few IRQ_xxx errors on USB devises while priming at 220 BCLK, but nothing is gone bad yet. High BCLK will push the SB and PCIe more, and probably Linx has shoot out your AHCI controller.
EDIT:
How much volt on SB did you have?
Bone stock on the SB. I'll definitely test this out with another harddisk, god that would suck if you're right. :(
Edit: Controller seems to be okay. Another disk installs just fine on the same port so I guess the raptor is faulty. I had it running on a cardboard box without extra cooling. Fun fun. Time for SSD maybe?
Good news, and yes you should go for SSD. I have been using a OCZ Vertex 30GB as OS disk (W7 RC 64bit) and can never think of going back to HDD again. It is cool, fast and quiet.
So I just decided to RMA the board, nothing would get it going just code 88 everytime... better luck with the new one I hope.
Yup, good luck! Acidic smell and boot issues for a new board, maybe a dud? I hope you get a new one fast. :up:Quote:

Edit: There seems to be a direct correlation between IOH volts and Linpack times. Going from 1.15 on both to 1.17/1.5 adds nearly 5 seconds to completion time of EACH run! More volts, less GFlops. :confused:
Is there any new beta BIOS on track?
will post back later prime 12 hours stable again
difference now is
vdimm at 1.58v for 2k C7
and vcore is now same as linx 100 pass at 1.24
ok here is what u do
set dram pwm to nominal
set vtt pwm to reduce 15%
set dqvref to +1.5%
also another note
cpu vtt add disable and vdropp disable
u either set both on enable or both disable.
Beta BIOS 2009-06-16 now available on DFI site but only as a Diamond Flash Image. Now also added the "useful" one... :p:Quote:

Factotum: You might be having a problem with Turbo throttling at full load. That's when your +1 Turbo will rapidly cycle on and off so your CPU multiplier will bounce back and forth from 21 to 20. That is likely why RealTemp is reporting 20.8 for your multiplier.
Try running i7 Turbo and keep an eye on what it shows for the Calculated Multiplier. Run Prime 95 Small FFTs and see if it is steady at 21.000 or not.
http://www.fileden.com/files/2008/3/3/1794507/Turbo.zip
If your Turbo is cutting out at full load then there should be an option in your bios to turn this off.

While Prime95 Small FFTs is running, the Calculated Multiplier should stay steady at 21.000. If i7 Turbo 6.1 shows that it is constantly less than 21.000 then that is a sign of Turbo throttling. Your bios looks like it is setup correctly. Try turning on the Log File feature of i7 Turbo so you can go back and see if the multiplier drops down for 1 second which might be reporting error or if it is constantly changing and dropping below 21.000. Post a piece of your log if you see a lot of numbers in a row below 21.000.

anomaly?
Factotum: How about reducing your overclock down to about 190x21 and run Prime95 Small FFTs again and see if this problem goes away?
Based on your bios settings, your CPU shouldn't be throttling but it looks like it is trying to.
Edit: Before doing that maybe try turning off Everest. This might be interfering with i7 Turbo.
confirmed!!! Turbo/RealTemp have conflicts with EverestQuote:

I need some help for my friend, he got his new setup today (DFI X58 + G.SKill Trident + i7 920 D0) and the mobo is only showing 2 cores instead of 4 (@BIOS on CPU-Z etc), we tried everything and still shows 2, any idea? please any help would be appreciated...
does anybody hear hissing sound from mosfet area under a load, or it's just me?
What bios did you use?Quote:

Well, im testing 2000 8-8-8-24 1t with 1,4v/1,65v vtt/vdimm, and seems stable in linx/prime blend/memtest+ :yepp:Quote:

Also I must say this board is incredible his first attempt he got the chip to 4.4ghz with HT on without any problems!! D0 rocks :eek: I wished I had one....
Got the new board, its up and running.... now for stability testing.
Congrats. Getting a second dud would make me RAGE.
Its not just you... My board sings like a drunken pig :shakes: Interesting fact, if i scroll up and down on the webpage - it stopps hissing...Quote:

Haven't heard a thing from my board.
Something like some graphics cards... Hissing appears only in stress testing - 100% load. And obviously, not all boards have this problem :confused:Quote:

Yeah I can't get to 235bclk it hard locked...anyone with a w3520 can pull off over 235 bclk CPU-Z validation? Or maybe it's an FSB hole? :confused:
By the way, I've found my Kingston Kit won't do CAS 7-8-7-20 2000Mhz Anymore the system just random freeze during PI. Maybe w3520's IMC is slightly different that the newest BIOS still didn't enhance it...
So far only managed to cold boot 230bclk and pull off to 232x19@1.3125v for a PI 32m run...
i can't hit even bclk 205 with my w3520, 205x12 cpu and 205x6 memory results in bsod under priming :(
i tried same with my old C0 and pass bclk 215, so i guess this is bclk wall in xeon

cold boot 232 bclk was successful (With QPI Fast Link Mode disabled)
now priming blend...
Okay I think I need some help with a memory problem. I'm running 6GB OCZ 1600LV Platinum sticks and the BIOS (0508) seems to mess up the subtimings. My chip isn't the best but it seems it can do 4.2 at 1.31/1.43 vcore/vtt, if I run the memory at 1200 7-7-7-24-1n I get 10 LinX runs and more without problems, now if I set the memory to 1600 it BSODs within 30secs. I took the RTL values from the 600MHz setting (63-66-68) and manually set them on 800MHz and now I've got two runs and after that BSOD. Any help?

At least it's good to hear that your second board works as expected! :up:Quote:

I have the same problem as you p2501. I dont run the latest bios but if i run 21x200 (ht off), mem@1200 i can pass linx no problem at all. If i get mem@1600 i cant pass linx no matter what. Always end up with bsod no matter the vtt.
So now there's 3 people having problems with running their memory at 1600. We need someone who knows his/her way around mem subtimings. I forgot to add that for me this behaviour started when I set the bootup base clock to 185 to get rid of this annoying reboot-at-26. Before the setup with 1600 was good for 9 LinX runs before BSOD.
Have you guys tried running memtest 86+ DOS version v2.11?
Let's see if you get any 'unhandled expection', or 'unexpected interrupt'
1+ hour run of memtest @ 1600 8-8-8-20 1.60v no errors at all.Quote:
