DFI LP UT X58-T3EH8 - First bench, bios screens etc

So, that can only be done using Nvidia cards then, right?

Yes. With win7 you can use nvidia card to do physix while running Ati card in ther slot though.

Back to PWM cooling again. Will mosfet watercool block from X38 be compatible with X58?
I have MIPS block already, but they have on their site this about compatibility:

What does it mean, mosfets on X58 are different from P35, X38, X48?

Eva,
on 1 page you have few pics from backside with backplates? Were all those backplates preinstalled by DFI?

Also, may someone pls measure dimension between memory sticks in slots 1 and 5, 1 and 6?

good question...is there a current mosfet/nb/sb waterblock solution?

distance between dimm slot 1 and 5 and 1 and 6 you mean ?

the backplates are preinstalled by DFI

At last time to play with the DFI and another i920, its better then me old chip :up:

http://img.photobucket.com/albums/v292/Viss1/3835A.jpg

nice that's better than mine which needs 1.328-1.344v for that with TRUE120 air :)

what cooling ? batch ?

Its with TRUE and 60 cfm fan in 20 deg C room. Batch: 3835A804. Only ran prime to compare it to me old one, hope it wil like high clocks like your golden week 36 :) You primed at 21x191 or 20x200 fror 4ghz? 20x200 seems to need more volts.

done prime at 19x211 as well as 20x200 fine same vcore :)

I hate you eva, you lucky SOB :D
I tried 5 i7 CPUs so far, and none liked even multipliers (always needed like +0,1V Vcore at same Mhz).

On another note, I just called Michael Franke vom Mips (sorry guys, totally forgot about that) and asked what the dfiference was between the Rev. 2 and the "old" PWM freezer. Well like I said, the PWMs are unchanged, 100% identical to the X38/X48 UT/LT. But it seems DFI set the 8pin 12V connector slightly different on the x58, which means you'll have to cut off a few mm of the older PWM freezer to make it fit, but he said it wouldn't be a problem. So if you already have the Rev. 1 freezer just mod it, otherwise go get the new one (it's just a bit smaller at the outer edge, otherwise identical).

Yes, may you say this distance? I am trying to understand if my memory cooler will be suitable at 3 or 6 sticks config.
And how do you think, if I going to use waterblock for CPU, do I need to use additional backplate? Or those comes with the board would be enough?

This is very good news, thanks alot! After all that I did with my poor case, it's just nothing to cut a few mm.

So the last question in watercooling would be what to use for NB (and what distance between mounting holes) and would be passive cooling for SB enough?
Where may I find foto of the naked board, without stock cooling?

IIRC Swiftech recommends addition backplate, so get Swiftech Apogee GTZ if you can

Dimm slot distance measurements:

• Distance between each of the 3 channels (1 green + 1 yellow) is ~3.5mm
• Distance between dimm slot 2 and dimm slot 4 with Corsair Domainator DDR3-2133 modules installed is ~14mm
• Distance between dimm slot 1's retention lever and dimm slot 5's retention lever is ~50mm
• Approximate dimm slot width capacity up to ~7.2mm - so that's how wide your memory modules can be in terms of thickness of heatspreader with modules side by side i.e. 6x1GB or 6x2GB configurations
• Corsair Domaintor DDR3-2133 heatspreader thickness ~6mm
• G.Skill PC3-12800HZ heatspreader thickness ~7mm

hi eva2000 what's your idle core temps @ 2.6ghz ?

depending on room ambient between 33-43C idle according to realtemp 2.90. Room temps can vary between 22C to 34C heh

Seems with 6x1GB AUTO CMD rate = 2T, so for 1T you need to change CMD rate from AUTO to 1T (1N).

Bumped vdimm straight to 1.830v in bios and clocked 6x1GB straight up to DDR3-1606Mhz 8-8-8-24 1T to see how it runs. Everest latency speeds seem to get slower as you add more modules. So in terms of fastest everest latency the order goes = 2x1GB > 3x1GB > 6x1GB. Still 32M time with 6x1GB DDR3-1606Mhz 8-8-8-24 1T is pretty decent.

6x1GB @DDR3-1606Mhz 8-8-8-24 1T at 1.830v bios (DMM measured 1.835v real)

Off to bed, so will do more tests tomorrow with lower vdimm to see how this mismatched 6x1GB config handles :)

Lol I can't even run 3x2gb D9GTR at these low voltage settings with 1600 CAS 8.. goes to show just how much depends on the CPU having a good IMC.

Oh yeah, I can't go to S3. S4 works fine but S3 will power down, power button blinking. When I hit the button it starts the mobo but hangs at "CF" so I have to shut it down & restart it like 2-3 times. Sometimes it will also reset BCLK (but not the entire bios).
BCLK too high? Tried at 211x19 and also backed down to 200... no go.

Oh yeah, official 114 bios.

I couldn't get my DFI LP UT X58 with the 0106 BIOS and my 920 to boot with a BCLK above 170. I've flashed the BIOS to 0114 using a bootable USB drive and will see if that helps. I started with the BIOS setting in the first post and adjusted them to my system.

I tried both Vista 64-bit SP1 and XP Pro 32-bit SP3. I suspect that I'll be doing a major swap of components with my P6T sooner than I anticipated.

CF post led and symtoms are all nearly signs of lack of vdimm voltage so try more vdimm and hence more cpu vtt :)

Running 1,5V VTT and 1,75V Vdimm and the crappy 6x mem divider (ram @ 1200 something). Seriously I can't give more juice. Also it's perfectly prime/linpack stable.

I'm confusing myself do you mean 6x mem or 12x mem ? I rarely experienced better stability with CPU VTT and VDIMM so close - usually for me the ideal gap (depending on modules used) is between 0.3-0.4v difference between CPU VTT and VDIMM. But then I haven't tried 2GB density modules yet.

6x1GB @DDR3-1688Mhz 8-8-8-24 1T at 1.830v bios (DMM measured 1.835v real)
Bumped Bclk to 211 and reduced vdimm from 1.830v bios to 1.815v bios (DMM = 1.820v real) for DDR3-1688Mhz 8-8-8-24 1T.

Slightly faster 32M Pi times than 3x1GB D9GTR at same main timings even though below 6x1GB was done with considerably looser subtimings for tRFC, tWTP, tRRD and tFAW in bios. Will try tighter timings later.

I started off with the voltages used in your template with both the 0106 and 0114 BIOS. I won't know for sure until at least tomorrow night after I do some more testing but with the 0114 BIOS I do see a definite improvement.

When I was using the 0106 BIOS I set the QPI Frequency to AUTO but with the 0114 BIOS I set it to 4.8GT/s. With the 0106 BIOS using stock settings of BCLK of 133, ratio of 20x and vcore set to AUTO the CPU voltage was 1.23v. Now with the 0114 BIOS my CPU voltage is down to 1.05v.

So I think my mistake was not setting the QPI Frequency. Just the fact that my initial vcore was 1.05v has made a big difference.

interesting for me always best to leave QPI frequency on AUTO

Best I can do with 6x1GB mismatched modules keeping voltages the same @879Mhz 8-8-8-24 1T at 1.815v bios (1.820v real)

When I say 6x I mean 6x, dunno why you are always doubling the numbers? When you say 6x you are using the 12x :D
12x usually doesn't even post for me :rofl: :shakes:

I gotta settle of a consistent definition of mem multis for myself - confusing myself sometimes LOL

Just call them as they are reported in bios.. 6x is the lowest possible, 1200 ram at 200 BCLK. 8x is 1600 10x is 2000 etc.

With a very bad batch (3838A), i prefer to use low voltage and resigned to 3.8Ghz. My RAM is 7-7-7-24 1.65v stock, but i need to climb to 1.71v in Bios, i suppose that because of the needs of the Uncore.
Overall, very pleased with these numbers and the board.

These setting work up to a BCLK of 172 but using 173 causes the system to shutdown and then will not boot until I do a Reset/Power Off to reset the CMOS.

A BCLK of 172 will work with a lower vcore setting but I've gone up to 1.45v with 173. I was using a lower DRAM and VTT voltage for 172 and raised it to the above values for 173 but that didn't help. I'm just about ready to give up on this i7 920 and try something else. Any suggestions before I throw in the towel?

I didn't take them as recommended. I just failed to use my full bios settings.:D

The following BIOS settings are stable but when I increase BCLK to 173 the system will not boot. I've tried a vcore up to 1.45v.

When I had this 920 in my P6T I got up to 4074 MHz with Turbo on (21x194) although not stable. I also had Prime95 stable for 30 min @ 20x195 (3900 MHz) but I stopped it because it was hot.

When it doesn't boot what postled code ?


play with PWM switch frequencies as well some memory like reduce 15% over nominal

and play with modules in different order for same dimm slots

also play with subtimings too

DRAM memory tips #1, #2 and #3 http://i4memory.com/102537-post3.html :D

Also have you tried bclk values other than 173 ? i.e. 174 or higher ?

I'm using 1/23 pre-beta bios and first time i came across this little bug i was testing 6x1GB mixed tri channel and 7-7-7-18 1t and slowly bumping bclk on 8x mem multi. Was fine from starting bclk of 150 up to 166. Then set 167 got postled 75 on bios exit/boot up and blank screen. Then tried bclk from 168 to 216 and had no probs with 6x1GB @859mhz 7-7-7-18 1T http://i4memory.com/f83/6x1gb-corsai...rclocks-14112/ heh

Hi Eva can you help me with oc my cpu please? I can't pass 3.4ghz even if I try to raise the vcore. I know I miss something here.

bit general there... elaborate as to what happens past 3.4ghz, huge diff between can't boot at >3.4ghz vs fail prime95 immediately vs getting bsods/reboots vs failing prime95 after 7 day straight run heh

you need to give us something to work with - aims/oc'ing objectives, system specs, cooling and ram used as what settings you've tried as per template here http://i4memory.com/f80/dfi-lp-ut-x5...emplate-12919/

Show us what you have tried and what did and didn't work for you. I still follow the same process i outlined at http://i4memory.com/f55/announcement...y-eva2000.html with every new system including i7/x58. Isolate and test each part of the system i.e. start with memory then cpu then the rest.

So in your case (and anyone else reading):

1. Find the limits of your memory before you find limits of your cpu/bclk.
2. Find out what your memory can do on each mem multiplier/cpu multi combination.
3. Find out what voltages your memory likes and what's the optimal voltage difference between vdimm and uncore (cpu vtt) for your particular ram/setup
4. Find out whether the ram likes pwm switch frequencies of reduce 15% or nominal.
5. Find out which of your modules likes which dimm slot 2 or 4 or 6.
6. Found out what auto subtimings translate to in cpu tweaker or memset at each mem frequency/timing combination.

stuff in bold could be more relevant for your situation

Basically get to know how your ram behaves on the motherboard with your particular i7 cpu before looking into the cpu side. Sure, there's a wide variance between i7 cpu memory controllers but I'm wondering how much of this variance is due to differences in how particular cpu memory controller interacts with different types of memory modules - down to their PCB/trace design ? Or just bios updates i.e. my Samsung HCF0 based G.Skill PC3-12800HZ didn't do too well with 12/18 and 12/31 bios and that effected cpu stability and what voltages I needed to use. Come 1/06 beta and 1/23 pre beta, HCF0 modules now shine and keep up with Corsair DDR3-2133 Dominator HCF0 and cpu clocking much easier.

Trust me when I say figuring out ram side will make overclocking the cpu much easier :)

thanks a lot Eva. by the way how do you get 1:1 ratio ? my goal is 3.8ghz if lucky 4.0ghz more than enough.
P.S. can somebody tell what are these switches for (circled in red)

so such thing as 1:1 lowest mem multi is 6x so 133bclk 6x mem = DDR3-800Mhz speeds

doubt DFI needs a voltage override jumper seeing as VCORE available in bios is 1.6 + 14.8% = >1.83v

one more question :> when I set cpu vtt voltage to 1.26v I get 1.21v in Everest & Smart Guardian. Vdroop is enabled. Eva I've read your tips but it seems to be a big gap in volts.

use multimeter to measure real voltage values so you can adjust accordingly

I usually get one of two codes: 75 or 88. When it's 88 I can't use the reset/power buttons to reset the CMOS. I have to turn power off at the PSU. Sometimes this takes a couple of times before it boots again. If it is 75 then I can reboot using the reset/power switches.

75 i get when vdimm and cpu vtt ain't enough for clocks set, 88 yeah means switch of psu and then hold home key while hitting power to revert to default bclk

loosen everything up and work back to tighter timings as you test

More results from me

Max 6x1GB 8-8-8-24 1T Clocks
Changing to 10x memory multiplier, tried to find max 6x1GB 8-8-8-24 1T clocks and ended up with DDR3-2000Mhz 8-8-8-24 1T at 2.04v bios (2.045v real) only for tried 1M Super Pi as 32M Pi test failed. I dropped bclk and mem clocks to DDR3-1960Mhz 8-8-8-24 1T at same vdimm but Super Pi 32M failed at 22nd iteration. Similar trend occured at DDR3-1940mhz as well.

I recall it's probably the Cellshock PC3-14400 Micron D9GTR holding the 6x1GB modules back as it needed more vdimm for do such clocks even on P35/X48 DDR3 boards closer to 2.1+ volts for around DDR3-1920 8-8-8-x. Decided to stop there as unnecessary stress to i7 IMC ain't needed when I shall have some nice DDR3-2000 CAS7 rated triple channel memory due my way this coming week :D ;)

What do you think is the max uncore stable on i7 920 stable?
The motherboard is this Dfi and the batch is 3838B079.. The cooling is True + 2x Noiseblocker XL2..

for me max uncore is around 4000-4400mhz frequency. Uncore all depends on memory and memory volts :)

how come some people running 920 @ 19 multiplier ?

i run 19x so i can run a higher bclk for better performance/ram clock frequency i.e.

19x211bclk vs 20x200bclk :)

Thank you "Memory Addict" eheh :D

so far I am able to get 20 X 200 @ 1.350v stable :)

It seems that I've overcome all obstacles that I had with my Patriot memory. Since I put my Corsair Dominator DDR3 2133 memory in I haven't encountered any problems. In fact I just started Memtest86+ v2.11 with these BIOS settings:

DRAM Timing: All AUTO
BCLK: 200
Mem Multi: 10x
DRAM Volt: 1.725v
VTT: 1.48v

Memtest86+ Shows the memory at DDR3-1998 11-11-11-28. After I verify this is stable I'll see if this can't be tightened up. Thanks.:)

as i suspected, ram plays a big role for cpu stability for i7 :D

I think i've maxed out my first i7 920 3836A756 with 4769mhz air validation, 4652mhz 32M air, 228-230blck max air. Just swapped in my 2nd i7 920 which is an identical twin batch 3836A756 as well. Hoping 2nd one is better than first! :D

what's your vcore ? did you change any other volts ?

anyone have to chance to test between this board and EVGA X58?

what distance should be between vcore(vdimm) and vtt ?

safe is 0.0v to 0.50v but what is optimal will depend on memory modules themselves, memory frequency/timings and mem multiplier http://i4memory.com/102537-post3.html (memory tips)

Id034, I owe you a coctail of your choosing. Used your settings from page 12, after primary vista install, first overclock of an i7, and is working like a champ!

My memory is on the 6 multi as It did not like the 8, probably voltage set too low. No worries, will play with that when I have a chance. 32m pi stable at this point so happy.

This is a build for a friends kid, a rocking gaming rig. Thanks again to eva2000 for all the info on i4memory as well.

It is up crunching numbers while I get some rest, see how it likes running 24/7 @ 100% cpu load on all cores with HT for 8, will check on it after some sleep.

Thanks again guys.

congrats linflas :D

Just swapped in my 2nd i7 920 which is an identical twin batch 3836A756 as well. Hoping 2nd one is better than first! :D

System specs

• Intel Core i7 920 3836A756 #2
• Thermalright Ultra 120 Extreme + LGA1366 Bolt Thru kit + 2x 120x38mm Scythe UltraKaze 2000rpm 87cfm fans in push/pull
• DFI LP UT X58-T3EH8 R.A51 - 01/23 beta bios
• 128MB Gainward FX5200 PCI
• Ram cooling: 3x 60x25mm Sunon 23.5cfm Maglev fans
• 80GB Hitachi 7K80 SATAII
• Pioneer DVD-RW
• 1KW Corsair HX1000 psu
• WinXP Pro SP3 full nLite updated hotfixes / Windows 7 beta dual boot

Seems this 2nd i7 920 3836A756 has as good a memory controller as 1st cpu. It has better CPU VTT handling as it requires noticeably less CPU VTT than 1st cpu and runs cooler under load too ~3-5C cooler. Although Prime95 isn't as good as 1st cpu. First i7 920 needed 1.232v for Prime95 @3815Mhz 4+ hrs rock stable while this second one only managed 40mins Prime95 @3815Mhz at 1.264v before system rebooted. But so far bclk wise it handles great hitting 201bclk at CPU VTT 1.21 (default) for DFI UT X58-T3EH8 board. Have yet to test for max bclk, but did a quick 32M run and it's probaby as good as 1st cpu. Fingers crossed it has a better max bclk than 228-230blck (1st cpu) :D

Nice, but seriously, set it to CAS 9-9-9-24 to start with. Anything above CAS9 makes no sense at all, run 2000 CAS 8/9 or stick to 1600 CAS7...

@The Mighty: Nice, I take it the Aquacomputer GTX 285 blocks are already out then ;)
Excellent choice on the MIPS set too, I love silver nickle :up:

Looks like I'm gonna have to use the Aquacomputer blocks as well, since they are the only ones flat enough to allow for addon cards to be placed directly underneath each GFX card.. even tho I'd really prefer to use Watercool blocks + their incredibly insane-looking 3-way-sli connector :(

Found the time to try out the official Win 7 beta on the UT, nice clean install without hassle.

@4GHZ is not final. I'm still working on it.

:welcome: Sam.
Looking good so far :up:

Well be testing the Corsair Dominator GTs with i7 920 and my rock solid DFI UT X58-T3EH8 motherboard so keep an eye out for the results :D

ooohhh SNAP !!! those are some sexy specks on the ram :D cant wait to see how high you can take those babies, i also got a triple kit of 2000mhz sticks from Gskill but cant bench until my DFi arrives from germany :up:

@eva2000, if you are a S3 user.

S3 sleep and resume works prefectly but remember to disable the WOL functions under the Device Manager else you get a insomiac PC bouncing wide awake back from S3 sleep all the time.

Awesome ram. Nice to see 2000mhz cl7 1T sticks with less than 1,5v vtt :up:

I could reallyuse some help here...

I can't install quad SLi on this motherboard. I've installed OS with one GFX card and then added the other, but the nvidia driver didn't see it. I saw it caused a problem on one of the PCI-E ports, not enough ressources (kode 12)

Then I C-mos and tryed to install OS with quad installed, but then OS could'nt find my raid 0 - untill i removed one of the GFX.

Someone have an ideer on what to do?

Is there a PCI-E bios setting that controls the ports, maybe..?

Thanks!

did you try without the sound card?

Hi guys. Has anyone tried fitting Swiftech's NB block MCW30 on here:

My guess would be this:

Memory LowGap: is for mapping local memory (add-on-cards) to system memory address size. It most like AGP port Aperture size or PCIE1gen 250M fixed mapping size. Extend it can solve when if "add-on cards" request a bigger size as like we would like to enable Qual SLI on NV new 295, it must be extend over 2048M. Can confirm that with 2x HD4870x2 in Crossfire I had set my LowGap to around 2176 at least. With Highpoint 3520LF PCI-E x8 256MB cache controller added into HD4870x2 Crossfire, I needed at least LowGap of 2560 otherwise windows boots to a blank window and doesn't go any further. As to how this effects windows available memory, with single HD4870x2 installed and 3x1GB memory, if I set LowGap to 2560, WinXP Pro SP3 32bit sees 1.5GB available memory. If I set LowGap to 1024, WinXP Pro SP3 32bit sees 3.0GB available memory IIRC.

I have a T3EH6 on an older bios but it is an option for me so I assume you have it as well unless they got rid of that option. IIRC it is under mem settings.

Back home, the bios has the setting and i changed it to 2048 and started a fresh install, good thing is that it can see the raid 0 again, so somthing has changed for the better.

Thanks a lot! :)

This is a build for a friends kid, a rocking gaming rig. Thanks again to eva2000 for all the info on i4memory as well.

It is up crunching numbers while I get some rest, see how it likes running 24/7 @ 100% cpu load on all cores with HT for 8, will check on it after some sleep.

Thanks again guys.

Not what is in my sig, this is a build for a friends kid. Have a MCR220, and a single Black ice120, on some weak ass fans that came witht he coolermaster Cosmos case, He wanted it quiet so did not switch out to decent CFM fans. An apogee GTZ also, and 2 mcw60's on a 4870x2 in the loop.

Ran WCG for a bit, was not stable for that, so had to make some adjustment, now at 200x19 for 3.8 @ 1.29V, memory @ 1600 Cas8 (gskil 1200 6gb cas 7 kit).

@ 4.2 WCG was heating to 67 or so, @ 3.8 holding @ 58 on all 4 cores @ 100% with HT on. So pretty happy with that. As this is not my rig, and I will not be around to tweak it if things go wrong, settlled on the lower clock to garuntee stability

Thanks again for the help, really gave me a good place to start.

Max BClock
Testing 2nd twin batch cpu and definitely this second i7 920 3836A756 is better than my first one in terms of max Bclock and low CPU VTT usage.

i7 920 3836A756 #1

• max memtest86+ bootable bclk = 224 requiring 1.58-1.60v CPU VTT
• max super pi 32m bclk = 222bclk (without IOH/ICH voltage tweaks) & 228bclk (with IOH/ICH voltage tweaks) requiring 1.60-1.61v CPU VTT
• max CPUZ Validation = 230bclk requiring 1.60-1.63v CPU VTT

i7 920 3836A756 #2

• max memtest86+ bootable bclk = 229bclk requiring 1.40-1.48v CPU VTT
• max super pi 32m bclk = 227bclk (without IOH/ICH voltage tweaks) & ???bclk (with IOH/ICH voltage tweaks TBD) requiring 1.48-1.50v CPU VTT
• max CPUZ Validation = 231bclk requiring 1.50v CPU VTT

TBD - Haven't tested 2nd cpu with IOH/ICH tweaks yet

Max Validation @231Bclock

CPU VTT = 1.50v

The crash i had was with the Raid driver from DFI, when I used Windows own driver it kept going and installed successfully... With Quad SLi!! So it did work! :up:

raid driver from cd-rom or web site ? tried latest from intel.com ?

Latest driver from DFI Website ( Vista X64), but raids working fine now on windows own raid driver. Performance of raid seems fine, so i'll avoid a reinstall.

I seem to be stuck at 19*200 no matter what vcore i use, but if i want to raise the VVT to help out, I'll have to raise the Vdimm aswell (as they need to be ~0,5V apart) My Corsair memmory are rated at 1,65 vdimm and if I'm not to exceed the limit, I'm stuck with a VVT voltage at <~1,21 V

Is it realy important for a 24/7 setup to have a vdimm at max the rated 1,65 V?

Thanks!

Nobody knows the longtime effect av Vdimm> 1.65v for 24/7. It is safer to keep it within the Intel's recommended limit for 24/7. But VVT needs to be 0 - 0,5V apart from Vdimm, so you are not stuck at VVT <~1,21 V.

Thanks for your input, I'll try to push the VVT some more, without raising Vdimm.

tuned, probably my next mb:up:

But that would be high VTT volts 1.6v wouldn't it ? Or am I missing something ?
If vdim is 1.65 then vtt can't be 1.6v ?

VDIMM needs to be within 0.5v of CPU VTT. But the ideal difference between the two depends on number of modules installed as well as the memory themselves and at what memory frequency and timings used.

Samsung HCF0 2x1GB liked 0.24-0.31v difference
Samsung HCF0 3x1GB liked 0.31-0.40v difference
6x1GB mixed HCF0 and Micron D9GTR liked 0.35-0.45v difference
3x2GB Corsair Dominator GT Elpida 50nm based likes 0.20-0.28v difference - hence the general trend to need more cpu vtt than samsung hcf0 but handle CAS7 timings higher than others

Those seem to be pretty good examples. The voltages are a balancing act. The difference between VTT and DRAM voltage affects stability. And to a lesser extent the amount of VTT influences the needed VCORE for CPU stability. Once past general guidelines it's trial and error to what each system is happy with.

i started to try push to 4.0ghz but i have problem to stabilize, i put 1.38 cpu vid and 1.48 cpu vtt, anyone knows how put more volt on nb?
this voltage its a pretty high to 4.0 or its ok, my temps its 33 in cores idle and 54c load. with 1.35vid and 1.42vtt in 3.8ghz

examples in sig already - finding that balance between the 2 voltages will allow your memory to clock higher/more stable. How you find that balance is through trial and error - i start with memtest86+ v2.11, then into windows for stability tests. I like to start with super pi (yeah some folks will say BUT...) but with i7 mem controller on cpu, super pi isn't a bad place to start at. I've experienced an hour blend prime95 stable only to not be able to even pass 2nd loop of super pi 32m before with i7 920/x58. Of course do both tests etc.

Yeah i found the right cpu vtt volts allow me to clock cpu higher with less vcore as well

for cpu clocking NB doesn't play much part in i7 920 anymore. Key volts are vcore (vid), cpu vtt (uncore) and vdimm (memory volts).

might start with some reading at http://i4memory.com/102537-post3.html ;)

Needs a difference of maximum 0,50 between VVT and Vdimm - not 0,05

In my experience, this is true up until @3.8.GHZ, HT:on, and 4GHZ HT:off, but it seams to need some more tweaking to stabilize @4GHZ, HT:on.

@4GHZ HT:off, i can prime for several houser, and pass memory tests with these values:

@4GHZ HT:off (200x20), 1.31v(load) and 1.26v VVT :
http://img120.imageshack.us/img120/597/4ghz8ah4.th.jpg


@4GHZ(19x211) HT:off, 1.28v(Load) and 1.29v VVT. This primes with 1.26v too.
http://img218.imageshack.us/img218/7...hz26zn9.th.jpg

But the moment it hits @4GHZ, HT:on, it fails at the moment i start prrime95 with 1.33v(load) and 1.32v VVT. I tried a few other Vcore and VVT too, but still fails/freezes at the first moment of prime95. This doesn't BSOD as usual (when it needs more Vcore), but freezes. It seams to need tweaking on other values. What is your opinion?

---

You have a big and important point here, and it deserves further investigation. Could this be the reason for less Vcore with my 1.29 VVT?.
@4GHZ HT:off (200x20), 1.26v VVT it needs at least 1.31v(load) to be primestable. But
@4GHZ(19x211) HT:off, 1.29v VVT it is primestable with only 1.28v and even 1.26v(load).

I never figured the reason for this difference, could that "little extra" VVT be the reason?
