Cool! Thanks once again...
Yeah, I've been having issues trying to figure out this combo of vtt/vcore/vdimm. I have the OCZ dual channel ddr3-1800 and it has max 1.95 volts. If I got in and set my memory first, like I always do, my VTT starts going up on its own. Herew's what I get:Quote:

1.905 1.40
1.920 1.42
1.935 1.44
1.950 1.45
So it seems to be moving vtt in sync with vdimm for stability? I'm getting ready to order an 1866 set and hope I can get 4GHz. I'm stuck at 3.8 right now and think maybe the high vdimm is forcing the vtt too high and is throwing vcore out of whack?
I just put in 0106 BIOS and retesting in hopes of 4GHz.
wish me luck

ps. you may want to shrink those images a little.
However, you had to use the triple SLI bridge for double SLI.
I think it would be useful if people post when they are having trouble with the board. Every board/CPU/memory have golden examples. The question is always what percentage is golden.
The key to this board, the only with a digital pwm VRD, would be the stability of the CPU voltage. Possibly they might have better QC then some; that is, at NewEgg and elsewhere some brands seem to have a higher percentage of DOA or users unable to get past 180-190 bclk.
I just ordered the DFI x58 board from Newegg, should be here Tues Jan 13. I'll be keeping my giga x58 ud5, so I'll be able to do a direct head to head shootout with same components, same Vcore so I'll report which board OCs better. I'll be glad to run any experiments on a request basis, just let me know.
i7 920
3x2gb Patriot 1.65v ram
2x gtx260-216 in SLI
Tuniq Tower 120
jjeeep :P, i just ordered from newegg DFI x58 :P, also ordered ocz gold 6gb 1600 cas 8, and of course i7 920
That could be the most cost effective setup OC possible. Did you consider the Platinum memory for $20 more? It might have had more OC possibilities with a little more voltage.Quote:

Following the guidelines, for safe high vdimm usage, you need to keep CPU VTT (Uncore) voltage within 0.5v of DRAM memory voltage. Seems the bios has a clever feature, if you try to initially set DRAM memory voltage to >0.5v difference from CPU VTT, the bios will automatically increase CPU VTT voltage to ensure there's always a 0.5v difference between DRAM memory voltage and CPU VTT!
nice, let us know how it goes :)Quote:

@The Nemesis: How did you get turbo to work? It doesn't with my 920... initial bios. And mine seems to hate the 20x mult too so I'd really appreciate the 21x.
C1E option must be enabled under cpu features and of course turbo must be enable in genie bios page.Quote:

http://img.techpowerup.org/090108/3d...280GTX sli.jpg
Yeah thanks... I haven't even started clocking the memory yet, trying to shoot for max stable CPU clock first.
@Jcool: im waiting for your first impressions, especially compared with the EX58 Extreme. I too have ordered a DFI. :yepp:
Hm ya... the Extreme sure was a bit easier to OC, but maybe that is because I am already used to it and know what it likes and doesn't like.
I fear I have a bad mount on the i7, as I am already reading positive load temps beyond 1,45V Vcore, which shouldn't be the case at -33C evap load temp.
One other thing I noticed with a glee of joy: DFI obviously didn't change PWM and NB mounting hole dimensions. I compared it to my X38 and it seems as though the Mips PWM freezer still fits the Volterras (78mm straight line hole distance) as well as my generic NB block (NB is 62-63mm not sure any more). I stuck to stock cooling for now because I wanted to see if it's maybe sufficient, but I guess I'll be mounting the waterblocks soon enough.
Now off to test the 21x mult.
I'll get mine DFI X58 soon , already ordered at K&M shop and just have to wait a "bit" till my firend tests 920 and mobo and sends it to Georgia
BTW which BATCH of 920 is better?
Well...im stuck on air, and perhaps because of this I will not be able to directly compare your results with mine. But I am still waiting for everything you can show.Quote:

I'll use a voltmeter to insure same Vcore and do two prime runs, 1.34v and 1.45v Vcore. I'm using a Tuniq Tower 120mm w/120mm fan at 2100 RPM
for benching (900 RPM for 24/7). I have to turn off HT for benching cause heat overwhelms with HT enabled.
BTW, for what it's worth...I have tested 4 i7 920's to date. Two were from Amazon.com LLC (sold and shipped by Amazon.com as opposed to one of their 3rd party vendors).
The first of these two was very weak, could do only 3.7 Ghz or so. The second was defective in that no matter what I did, it would max out temps on all cores at 100C within a couple minutes. I sent both of them back, the point being that they both were very similar in their batch numbers and version nums (#....-002) and pack dates. I ordered a third chip and when I got it, I saw the same info as the other two bad chips and decided to send it back without opening it. Now maybe there's nothing to it, just bad luck, but I would stay away from Amazon.com LLC as a source. the two 'good' chips were version num #....-001 and were right in the ball park of expected performance. Not great like eva2000, but at least average from what I've seen on this forum. To be clear, I'm only complaining about Amazon.com LLC, not BuyNow.com, which is also a vendor on the Amazon site. One of the two 'good' chips was in fact from BuyNow.
Update: Make that 5 920s tested. Just got another from BuyNow.com. Looked at the sticker, another week 41 chip, version#002, a bad sign. Sure enough, a dud. This one runs cool, but can do only 3927Mhz in my standard prime run of Vcore=1.344 HT off, Tuniq Tower 120 at 2100 RPM. My 'good' chip has done 4116 Mhz with identical settings and components. My two good chips are both week 37, version #001. Are the later chips generally weaker, or is this just a coincidence?
Guys,
I am having real issues here.. Can't get the damn system to boot with EIST + turbo enabled. Not even at 4Ghz (I gave 1,5V+ Vcore so that's not the issue). Same settings work fine when I disable EIST (200x19 and 200x20 even tho 200x20 needs enourmous amount of Vcore, way more than 220x19 for example - I think my 920 just hates the 20x mult which is why I need the freakin 21x to work)
Any suggestions?
It's a horrible story. We hope that Eva lights this problem.
BTW my 940 in 20x200 in ex58 needs tons more of Vcore than 19x211.
what r u trying to run the ram at using this multiplier and what do you have cpu vtt/qpi voltage set at? If your running your memory on the 10 multiplier this board seems to have a need to boost the vtt/qpi voltage. It happens to me @ 20 with turbo disabled. Enabled no issue.Quote:

what batch/fpo ? and yeah 20x multi is harder to clock on most boards as it's running cpu at full power, turbo with eist I don't think the cores are always loaded and there has to be some form of speed step involved as i benched wprime which stress all 8 threads at 200x215 vs 210x21 = 4.3ghz (non-turbo) vs 4.4ghz (turbo) and times were identicalQuote:

don't forget to use bios template to share you settings used http://i4memory.com/f80/dfi-lp-ut-x5...emplate-12919/Quote:
I tested 21x205 and 21x210 for Super Pi 1M, 8M, 32M and 3dmark06.
Notes:
- Seems at high bclks like >210, when you move the cpu multiplier up and then raise bclk i.e. from 205 to 210, it can get to a stage were the you'd need to increase CPU VTT even more despite the same higher bclk (210) being stable at a lower cpu multiplier at a set CPU VTT value.
- I experienced this as I passed Super Pi 32M @21x210 = 4410Mhz at 1.4875v but couldn't get 3dmark06 to pass cpu tests even with 1.55v vcore by itself with CPU VTT at 1.48v which was stable for 220bclk on lower cpu multipliers.
- Tried raising CPU VTT by itself to 1.55v and vcore at 1.4875v still couldn't pass cpu tests in 3dmark06. Then remembered sometimes Core i7 cpus like to have vcore and CPU VTT within 0.02-0.03v of each other. So tried vcore 1.525v and CPU VTT at 1.55v and 3dmark06 cpu tests passed with no problems!
EVA...Looking at your settings I don't know what 'VID' is although it's referenced in giga boards also. Explain? After 5 weeks or so with my giga x58-ud5, seems it's pretty straightforward to get max OC. Just increase Vcore and Vtt and get higher CPU clk up to the limit of the chip. Is it pretty much the same with the DFI board, I'm asking cause a lot of your settings don't exist on the giga board, so I have no idea if they are critical or not. I want to leverage your superb efforts as much as possible so I can get to max CPU clk as quickly as possible when I get my DFI on Tuesday. Finally, did you obtain your CPUs in Australia?
No, was using the x8 mem divider and x16 BCLK.Quote:

WTF guys...
@eva: It's a 3838A so brand-new. How do you set the fixed 21x mult? In bios I can only select the 20x max and the turbo 21x is there in grey.. I am guessing my CPU might just hate the 20x so much that it won't even get to run the 20x with mult set to 21x, EIST and Turbo enabled :(
Not even at 1,55V and -20C which is weird tho?
for fixed 21x multi, you have to set Vista Power managment to High performance ...
Thanks... but I think I know what the problem is already :(
My CPU is just really really crappy... it can hardly do 4,2Ghz stable with 1,58V :rolleyes:
I need a better one, and fast.
Same here: 3838A. Already on saleQuote:
@eva: It's a 3838A so brand-new.
Yep mine definitely sucks. 213x19 is all I am gonna get out of this crappy thing stable... It doesn't work right with 20x or 21x mults, not even at 1,6V Vcore :p:
I'd like to ask Eva Unit 02:D a couple of questions but first let me say that my DFI LP UT X58 will ship in a couple of days. Since this is going to be my first DFI motherboard I've been doing a lot of reading to prepare for the occasion. The online manual that I downloaded omits the BIOS information. If it wasn't for your website I would be totally in the dark.
First, what's the purpose of 'Memory LowGap' and what determines the value used?
Next, in the 'Voltage Setting' section I don't see how you set Vcore. There's 'DRAM Bus Voltage', 'CPU VTT Voltage' and 'CPU PLL Voltage'. Will I be surprised to find a BIOS section in the hardcopy manual?Quote:
DRAM Timing
Memory Control Setting: AUTO
Memory LowGap: 1536M
I know that I've got a lot of other question but I'll stop with those.
I retired my 920 in favor of my 965 but I just might try it first.
920 batch #: 3837A902
965 batch #: 3838A610
CPU VID Control = VcoreQuote:

As to vcore above photo CPU VID control main vcore options with CPU VID Special Add which allows additional volts on top of main vcore in percentage increments up to 14.8%Quote:
Memory LowGap option 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.
It seems that I've got a lot more reading to do.:DQuote:

In EX58 Extreme i have spent a couple of weeks with Linpack stability @ 19x211 1.38750 Vcore/1.28 IOH/1.34 Qpi/1.66 Vdimm. (20x200 tons of more volts needed). But for a couple of days the system has become insane. He has lost all its stability and is asking more and more volts. Board on sale (tomorrow arrives my DFI), cpu on sale, mems on sale...
I see a bad trend...my 3x week 41 were all the weakest. jcool is unhappy about his week 38, which is better than my 41's, but worse than my 2x week 37s. My week 37 is way worse than EVAs week 36. So 36>37>38>41. Seems that the later the chip, the worse the AC characteristics. At this rate, by week 44, we won't see any chip booting into windows above 3.7G. I can't think of any reason Intel would deliberately mess up the chip to make it run slower. I suggest that everybody start including their batch nums in their posts at least once so we can correlate week number with OC ability.
Mine is a 3838A685. I should have taken the 3835A but thought newer was better, duh.
Something interesting: My chip runs WAY better with HT off, even though I am obviously not temperature limited. 4,4 to 4,5Ghz easily 3D stable, the setting below even went through 10 mins of prime at 1,550V load Vcore:
http://database.he-computer.de/Bilder/temp/3d06i7.jpg
This score any good for a single 4870X2? Haven't benched in ages really :shrug:
without HT you loose a bit in 3dmark06 at least - stock 4870x2 750/900 = 27,360kQuote:

I want to arrive to 4GHz!!!!
ByE!
I just got my DFI x58 up and running, flashed BIOS to latest (Jan.6) here are some of the problems:
I can't get turbo mode. I enable Intel turbo in BIOS, but all four multi options are greyed out , e.g. "if all cores enabled, x21". When I boot into windows, CPUZ reports I'm at x20 multi, which means no turbo. How do I get the BIOS multis to not be greyed out, and how do I get Turbo to kick in once in windows.
I have configured my voltage and multis in BIOS to be same as my giga UD5 board, but with same settings and components, this board is a terrible OCer compared to my Giga board. Id there a trick I don't know about? my multis are 8/16/36 memory/QPI/uncore.
With the Giga board, it was very straightforward...adjust Vcore and Vtt and set multis and after that, it's just a matter of how good your chip is. But with the DFI, there are a number of mystery settings that I have no idea what they do. There are somethings I like about this board vs the giga but I'll have to send it back if I can't get it to be at least close to the giga in OC.
So in summary, how do I get Turbo mode to kick in, and what is the secret setting to make this board OC correctly?

This has been answered so many times in this very thread but once more can't hurt I suppose.Quote:

This board is definitely harder to overclock than my gigabyte was so your not alone.
Guys,
one (for me) important setting that differs from eva's template: "Set VR Current Limit Max" must be set to enable or the CPU drops to non-turbo mult (22x in my case) when priming at 1,5V+. Since eva isn't much for testing stability I guess he just didn't realize ;)
why prime and 1.5+ vcore that's like unecessary torture for a cpu especially for me on air cooling...Quote:

No one in thier right mind should even be thinking about running Prime at 1.5v+, unless under very good Phase :eek: As eva2000 has said, there is a world of difference between running Super Pi and Prime.Quote:

Lol - you do run prime if you want 4,4-4,5Ghz for 24/7 stable clock like me. You can do that if you are on chilled water or phase ;)Quote:

I have a little issue with my config. I canīt turn off the f.....g pc normally.
This Enermax have a feature that turn on again for a few seconds all the fans when you turn off the pc, but with this dfi works like a reset :shrug:
Is annoying.
Anyone with Enermax+dfi x58 combo?
Enermax + DFI is a bad combo in general. The Pro82 and Modu82 series work fine, but Liberty/Galaxy/Infinity have known issues with all DFI mobos. :/
I know, i had 2 libertys dead with my old nf4 ultra-d, but i thought issues are solved in new generations. Maybe no :D

I still need to find a voltmeter test point for Vcore, there aren't any obvious ones like on my giga. Until I verify that I am indeed using the same Vcore on both boards, I can't be 100% sure that the DFI really is doing less CPU clk at the same voltage.
Can't get much easier then this.Quote:

OK, I'm going crazy getting three video cards to work nicely. I have a pair of 9800GTX+ and added a 9800GX2 to the mix. I all of a sudden get extremely slow boots (30ish progress scroll bars at boot time).
I'm getting weird issues:
It boots with the second DVI port on the GX2 in slot 1. But switches to 9800GTX+ in slot 2 during progress bar and I have to type my password blond and then it switches back to GX2 (well sometime).
I have big issues with the second 9800GTX+ in slot 3 registering at all. Device manager only show 1 9800GTX along with the two 9800GX2.
I tried unplugging my second monitor from slot 2 and removing my vga dummy plugs so it registers only the 9800GX2's second port, but it still picks up the 9800GTX+ in the second port and nvidia's control panel there is a standard vga monitor plugged into it.
This is sure getting whacky. Right now I just finished reinstalling vista ult x64 and hoping it smoothes out for me. so far it shows 2 std. vga cards installed. I'm guessing both 9800GX2 ports.
Any tips for getting all three vid ports going at once (non-sli)

Previously I had reported that my x58 board was a poor OCer. I stumbled upon the problem, it was a bad DRAM setting. In auto, the bios was setting the RAM to 7-7-7, which is way out of spec. I changed to correct 9-9-9 timing and reran my OC test. I had already determined that the same components in my other mobo, a giga ud5, passed prime95 up to 21x194 or 4074Mhz CPU clk. For reference, we're talking:
i7 920 batch 3837A728
Patriot viper RAM, 3x2GB
Tuniq Tower 120, 2100 RPM fan, 75F ambient temp
Vcore 1.356V---this is not BIOS or CPUZ, this is measured with a digital VOM while loaded by Prime95
HT disabled
After correcting the DRAM settings and making sure all other multipliers and settings were the same, and the only variable was which mobo I was testing, the winner is......a tie! That's right, both boards passed 21x194, failed on their 21x195 effort. The temps reported by CPUZ were in the 64-68C range during testing on both boards. I still need to do more testing, the CPU I used was not my good one so I'll need to see if my good CPU will equal the clock I got a couple days ago in my giga board.
So now it appears it all comes down to features and what is/isn't broken that's supposed to work. For example, smart fan doesn't seem to work as it is set in BIOS, but it does work in software. Also, vista sleep mode works in both mobos if you call 19 second resume time 'working' considering 5-10 seconds is normal. DFI has the edge here. It doesn't do the 6 seconds reported by EVA2000, but it does 13 seconds to 19 for the giga.
You actually left ram timings on auto? On a DFI? Oh the blasphemy :p: :rofl:

Thanks
Looking at that image I see that you have IOH labled w/QPI. So is the IOH 1.1v in the bios the same as the QPI frequency we see on the boards from other manufacturers? If so that would explain why so many of us are having trouble getting this board to clock as our previous boards. Most of us are not raising that voltage very high. I noticed its labeled nb core in smart guardian.Quote:

weird one, i pointed your post to someone at DFI see if they had come across this. with all the vga devices in there remember to play with memory lowgap option in bios >2560 but if you only have 3gb ram you could probably be lacking available memory left i.e. for 3gb with lowgap 2560 with my 2x hd4870x2 + 256mb cached highpoint 3520lf raid controller, I was left with 1GB available ram in windows xp pro sp3 32bit IIRCQuote:

depends on module's SPD, i.e. my dual channel rated g.skill pc3-12800hz d9jnm based 7-7-7-18 rated modules have much more tighter spd for subtimings on auto than my other dual channel kits with 8-8-8-x rated spds.Quote:

Enough for a quick boot into windows for a CPUZ Validation at least :D

Nice going eva!
Which bios do you prefer, 12/31 or 01/06?
Currently I am having trouble upping the ram mult.. I got my 4,4Ghz 24/7 stable but this 940 usually won't even boot into windows if I so much as raise Dram/uncore to 8x/16x :(
That is using loads of VTT, different Vdimm settings, and really slack CAS9 timings that are memtest stable for hours (hell I passed memtest easily at 7-6-6-15 1600, that's not the issue).
Do you think the CPU simply requires more Vcore to run the mem higher? If so that would suck cause it means I'd have to step down from 4,4Ghz 24/7, or run 1,6V :p:
Any other voltage having an impact here besides VTT and Vdimm? Maybe I haven't hit the right correlation between VTT and Vdimm? Although it seems stupid having to fine-tune the mobo to that extent only to run 8x mem divider at 192 BCLK.
Also I thought maybe there are variances depending on which CPU mult you use, so I tried 21 and 23x.. same disappointing results with both. At least my crap 920 could run mem like a champ...
Not even talking about the 10x as it is still unusable (needs 2,05V+ Vdimm).
Thanks, I like 01/06 as previous bios my G.Skill PC3-12800HZ D9JNM and Samsung HCF0 modules didn't boot properly (HCF0) and weren't as stable (D9JNM). 01/06 allows my Samsung HCF0 to shine - see below :D
I haven't investigated the relationship between each mem multiplier in detail yet - but yes higher mem multi max ram clocking harder i.e. between 8x versus 10x versus 14x but look carefully at your subtimings on AUTO at each mem multi and at each mem frequency you test particular tWTR which on AUTO or even when set will have different values at different mem multis as well as at different mem frequencies if you check using cpu tweaker and/or memset latest versions
Max BCLK with 10x Memory Multiplier
- limited by memory max overclock frequency
Now to try max Bclk frequency with 10x memory multiplier - ultimately will be limited by how far my memory modules can overclock :)

I am feeling rather reluctant to go play around with memory settings though, as I got a black screen testing 190 BCLK and 8x ram mult (again), but this time it wouldn't come back up. No amount of CMOS clearing, disconnecting and reconnecting from/to the wall helped, had to remove battery for 2h before it would fire back up again. :shakes:
And in that process I noticed my 940 has like the lowest cold bug ever.. below -40C it just won't come up, mobo starts with "88" and that's it.
Starting to believe this chip is also a crappy one, in its very own way (mIMC/coldbug/what else?) :shakes:
Seems that with i7, you can't judge a CPU anymoe just by how high the Mhz will go, but rather how high it'll go at decent memspeed.
Yup that's what happens when you have an IMC on-die. It kinda sucks because that sorta seems to be the problem with my i7 920. It will run 4Ghz at 21x190 but it's not wanting to do it a 19x211 regardless of me upping the voltage to the QPI to 1.45v+ and VDIMM 1.75v+. I've seen others however do much better on 19x211 and are able to lower their vcore.Quote:

Well that depends on your BCLK and the quality of your chips IMC (and also on whether your mems can actually handle 2000 Mhz), but I guess you'll need at least 1,5V VTT, more like 1,55-1,6V to be stable.
Also don't forget the 10x divider is still bugged on the DFI, meaning it takes more Vdimm than it should. For example, I need 2,05V to pass memtest at 2000 CAS 8-8-8 with my 6GB CSX Diablos using the 10x divider, however if I run it at the same speed using the 12x or any other divider it only needs 1,95V to pass.
Of course none of these settings work in windows so far, so I'll need to fine-tune that freakin thing some more. Seems I got a crappy IMC anyway. AND a coldbugged CPU as well, argh :rolleyes:
You aren't clear what you have, what your budget is, or what you are planning to do.Quote:

If this is a first Core i7 restricted budget build, the DFI would be a great board IMHO (my experience limited to the UT P45). However, the Corsair EX1000 PSU, often available with rebate for $200-250 would be more cost effective.
Another factor is if you are overclocking and your experience. Everyone looks at the max overclocks. I also look at the work that went into them, and how many people have trouble achieving low overclocks. That is, are there lots of posts about being unable to reach 200bclk or 4Ghz.
Even worse are lots of NewEgg posts about DOA boards. A problem with Gigabyte in general according to the NewEgg posts; on the popular EP45-UD3P, they had 5 consecutive different (lengthy) posts about DOA boards at the top of the list. It is easy to be lulled by often unused features or reports of 600Mhz FSBs.
The DFI board seems, by my observation, to require some expertise to OC because it doesn't always default as expected and may have some nuances at specific speeds and combinations. However, it also seems to have both the fewest reports of failing to make acceptable OCs and a large number of reports (relative to the total number of reports) of people making high OCs. Or even EVA2000's outrageously high OCs, matching some cascade phase change people while cooling with air.
Thanks jcool. What should be a safe vtt for 24/7 oc?Quote:

That's the point where I asked help on :)
It's my first core i7 board + I'm new on Oc...
Maybe this is not meant to be for me:rolleyes:
How the heck do you get the vtt to go lower than 1.26v since it defaults at 1.21v and overvolts by .05v? I'm trying to settle in on a 24/7 low volt overclock but this thing overvolts everything! I think this board is gonna end up a testbed or in the closet. I need a 24/7 gaming board with a nice 4GHz oc decent volts and timings. Both my chips seem to bench 4GHz 1.35v or so but 8hrs prime takes 1.4v.:rolleyes:
I think as of yet, no one can truly answer that. Intel max spec is 1,375V on VTT I think, but in order to get a decent OC to be 24/7 stable, you gotta go way past that point. I am currently running around 1,48V but am on phase and still on lowest ram mult, running high memspeed with 6GB+ WILL need >1,5V, more like 1,6V to be stable.Quote:

@Nemesis: I always wonder how he can even boot at the low VTTs he uses :p:
Must either be the chip (great IMC as opposed to my sucky one) or the fact he's using 3x1GB :shrug:
Oh yeah, I think I have a confirmed crappy IMC. Tried your settings for ram subtimings EVA, also 2T and went up to 1,6V VTT, 8x ram mult still crashes at 23x192 after 20-30 minutes of prime or 5 minutes linX :(
Uncore seems to work fine, currently running 6x Dram / 20x uncore, 2h prime blend stable :up:
I just don't get how it could be THAT crappy. I mean, it's supposed to support Tri-Channel DDR3-1600 right? Well obviously mine doesnt :down:
2000 CAS9 worked fine on the 920, so I know it's not the board or ram holding me back. It really is the IMC :shakes:
Definitely i havenīt luck. I have seen people with the same gskill pi black than me doing 1800+ estable at 8-8-8-21 1,65v, but my kit canīt load windows at those settings, even with 1,5vtt :(
try playing musical chairs (dimm slots) with your 3 modules as they might like particular dimm slots - helped me with my 2 sets of 2x1GB G.Skill PC3-12800HZ D9JNM based modules on DFI UT X58-T3H8 and also play with DRAM/VTT PWM Switch frequencies as well - some of my modules like Reduce 15% over Nominal setting but can vary depending on cpu/mem clock for some modules. My 2x1GB OCZ PC3-14400 Platinum D9GTR, 2x1GB Cellshock PC3-14400 D9GTR and G.Skill PC3-12800HZ D9JNM based modules handle better with like Reduce 15% over Nominal setting but my Samsung HCF0 based G.Skill PC3-12800HZ and Corsair DDR3-2133C9DF like Nominal.Quote:

Thanks eva. I play with sticks and slots, and voila! rock solid 1800 :rofl:

PD-Donīt look vcore(high), im testing only ram.
Lol? Are you serious? Man, time for some DIMM swapping I guess :rolleyes: :shakes:
Yes, totally serious. Strangest thing ever :shrug:
Are there any option to recover from a bad overclock settings with default config instead remove battery?
U tried this already?Quote:

I just got my DFI x58 board a couple days ago. I got it mostly because EVA tested vista sleep mode and reported that it resumed out of SM in 6 seconds. To my great disappointment, my board resumes in a very slow 14 seconds. So either there's something wrong with my particular board, or, 14 seconds is normal and therefore there's no point in getting a replacement from Newegg. I have to make a decision in the next day or two so I'm appealing to anyone who has a x58 board to do a simple test...put your x58 board to sleep, and time how long it takes to resume, power button to desktop reappearing. Thanks.
it always pays to test each memory module and in all combinations on dimm slots for whatever board you use you will find tiny differences which may help :DQuote:

8 extras too long to wait ???
How devices you have installed on pc ? usb connections etc ? check your windows event log as it will log your resume process
