So what I said is still valid, just insert the 20x mult :shakes: Ofc you can "have" the 21x mult for lower OCs and without HT, but then you won't need it in the first place ;)
Actually depending on how your bios is setup, you may be at actual 4.2. When running prime since all 8 threads loaded, if you are still at 4.2ghz, then you are at 4.2ghz. Or put it this way, any app you run on your computer will be at 4.2 ghz speed, hence it would be incorrect to say 4ghz. No difference to apps running with an i940 set to 21x200 with turbo off vs i920 21x200 with turbo on, if TDP/core limit is disabled in the bios and cpu is in permanent turbo mode.Quote:

What is nice about permanent turbo, it takes a few notches less vcore to do 4.14 with "permanent" turbo enabled vs 4.14 with no turbo. On my i940: bios F4j
1.35vcore bios = 4ghz 182x22, 12hrs prime stable turbo off
1.42vcore bios = 4.14 ghz 188x22, prime stable 4hrs (did not try longer), fails below that, turbo off
1.381 vcore bios = 4.14 ghz 180x23, prime stable 6hrs so far, turbo on (perma-turbo bios)
Just because it takes less vcore for all your apps and computer to always run at 4.14 or 4.2 with turbo on (in TDP/core limit disabled bioses), does not mean you are not at that speed, it just means you got there with less vcore.
^ Couldnt have said it better
Are you completely sure it won't go down any more? If so that's great news, and you can get +1 mult for real then :yepp:Quote:

Hey guys. I have been trying a few days to achieve 4.0ghz on my system.
I have a 965xe, a X58-UD5 bios F4K, and 6gb of Corsair Dominator. .So far I have tried 133*30 1.375v, 125x32, 200*20. I can boot into windows under all of these configurations. However, it will blue screen if I try to Prime95.
I have read to keep the memory multiplier at half of the QPI link? Does anyone have tips to get my system to 4.0?
thats intresting !:DQuote:

4.2 ghz is a B:banana::banana::banana:h , prime keeps getting me @4.2 ive taken it up to 1.518V vcore, and 1.515 qpi vtt and was running prime but i noticed red light flashing just under north bridge , so i thought red means stop ?
Positive. Intels boards shows (visible setting) the core limit/TDP settings, disable them and turbo = max multi +1. I asked GB tech support to relay a message to ask for 9x mem divider and to make the TDP/core limit settings visible to play with, sometimes they try suggestions, sometimes not have to wait and see.Quote:

See pic from intel board. See second pic with prime, ht on, turbo on, linpack and prime running simultaneously load 100.3%, realtemp is using intel white paper on core i7's so load is accurate.

Xello: You'll have to ask rge. That's a pic of his i7.
rge: Thanks for that info. That'll be an easy fix.
The i7 sensors are supposed to be new and improved. They still seem to have some slope error where the CPU temperature changes slightly differently than the sensors indicate. Harder to tell though with some Core i7 cores possibly being turned off at idle.
In theory, if these sensors don't get stuck, they're capable of reading down to -27C. Most of them will probably get stuck before that point but it would be interesting if someone could do some testing. It gets to -40C here in the winter but I'm afraid the neighbors will be calling the guys with the white jackets to come and get me if they see me hauling my computer outside, again. :D
:ROTF:
I think i have RGE's settings somewhere, cheers.
Prime just crashed again, approx 3 hrs 10 mins into blend test. All stock settings... :mad:

Any idea's? Memory is corsair non dominator stuff rated at 800Mhz, currently at somethign like 835. Got 1.65V going through the ram, so all should be fine.
The processors primes fine at above 3360Mhz (primes fine for 12 hours at 3.5Ghz) but i only just noticed it was on 4GB and not till i went back down to 3360 did it post showing 6Gb of ram grrrrr :shrug:

Welcome to the party Hornet, i'm having a blast with my board so far. I'll leave fine-tuning for later, right now i'm just having a stab at some quick OC's. Right now i'm booted with turbo off @ 200x20 for 4ghz, 1.4v vcore, 36x QPI 1.35v QPI/VTT, 8x memory for 1600mhz @ 1.66v, 17x uncore. Quick superpi 1m gives 10.3s, also prime stable for half an hour which is a good sign - this is going to be nowhere near as hard as i thought :)
What i don't get is all the pictures i'm seeing of people loading @ 70-80c, i'm sure one guy was going to TJmax and not worrying about it. I'm only on 1.4v vcore but my EK is giving me pretty good 47-48c 100% load temps with prime. Is water just really good for i7?
i am 200x20 turbo ht with a 920 under water and 12 gb corsair TR3X6G1600C9, it's np run 12 gigs on this board.
What Vcore and what are your temps like?Quote:

If i go to a 190x20 can lower vcore till temps under 60.
Gaming never got to pass 50 with 4.2 ghz running :)
My chip at begin got problems reach 190 but more time passing more i see it can go up, funny
Thank you.
i think voltage on qpi is more the key to high block with high multi than vcore, at begin i even tried a 1.55 vcore but with a low vqpi 1.28 was not even getting at loading os.
All others voltage but pcie one, i raised them one step over stock.
Cant wait to find a gtz with 1366 mounting or a cpu-350 block here in italy or rather near, i think temps will go down another 5 :)
I was just looking at that koolance block (350). I think I might just mod my GT as it did pretty well with a Q6600 at 1.54v.Quote:

Tried linpack as well as prime already, seems fine. Tried with 170 but it's no go, linpack freezes after 10 seconds. And it's NOT the mem, I set it manually to CAS 7-7-7-20 and it works as well with 160 BCLK.
Note that if I change any of the voltages except Vdimm and Vcore manually, or if I adjust mem mult, the mobo won't post anymore with 12GB. It's really strange behaviour...
Also, if I save that 160 BLCK setting and restore it after a no post, it won't post again even when the setting is perfectly stable. Have to go through the whole 1.-3. ordeal again (only with 12GB that is...) using optimized defaults as active baseline. :shakes:

QPI/VTT at 1.6v+ is key just as i initially thought

New BIOS for GA-EX58-UD4P - F3
I'm running the Extreme board, i920, Noctua hsf with extra 120mm fan and I'm getting temps of 90C under full load with prime... then it just randomly powers itself down (the entire system).
I'm running someone's recommended voltages from a few pages back, I think ~1.392 in windows vcore and a few other voltage increases.
Anyone got a clue on what it could be?
thats seems pretty hight to me :confused: got a link? :cool:Quote:

yeah man i'd probably be ok with 1.55 for 24/7 but not so sure about more
Yeah and default VTT is 1.1v, 1.7v does seem quite an overvolt for normal use. I guess time will tell.Quote:

What are people finding their max stable bclk to be? With all everything else turned down, cpu / memory / uncore multi etc. I'm at 222 and going for 230 next i think.
Xello, 222 is hard line to step over. :(
Benny's word record on i7-920 ES (229+) is greatest result.
There is some kind of hardware bug in C0/C1 stepping, IMHO.

Guys, what is your max NB freq?
I have only 4200 Mhz SuperPi 32M stable on Vqpi = 1.555v and Vqpipll = 1.44v, cold water.
I see dinos22's SuperPi 32M i7-920 WR taken at 4400+ Mhz on SS.
Is extreme cooling significantly improves this freq or it is total processor-dependent?
You ain't kidding, suffice to say 230 was a nopost :rolleyes: Even after going from 1.38v to 1.5v VTT and upping QPI PLL a bit, no luck.
Strange though to go from 100% 9hr prime stable to nopost in just 8mhz!
I also realized i have QPI in 'slow mode' and that i'll want the lowest normal multi (36x) max bclk if i want to base an actual overclock on it. @ 222 that puts QPI at like nearly 8ghz, i'm guessing that won't be stable :eek:
Brings me to another question, is there any general idea of what VTT volts are needed relating to QPI / uncore clock? ie we have good idea of min-max voltages needed for the cpu's between 3ghz and 4+ghz. What about the new clocks? I know some of you guys are saying VTT up to 1.65v is safe for 24/7 no problem but what kind of clocks does that give you? (I know it varies from chip to chip/board, generalise :D)
There was an article on either toms/anandtech...but have to go back to work now, so cant look for, but VTT/QPI voltage scales not only on uncore mhz, but also on amount of ram, as more ram places more demands on mem controller...in addition to diffs in chips, matters a lot whether using 3x1, 3x2 or 12 gb of ram. I am using 3x1 since still on xp 32bit, which is why once I am at 1.30-1.32 VTT, using 18x uncore, raising it more does nothing for me. Those with 6 and 12gb probably on average, benefit more...we need a big chart somewhere of everybodies details and overclocks would be interesting to learn from...and no I am not offering to do it.:D
Okay guys,
figured the whole 12GB deal out a lot better I guess. It all depends on QPI/VTT like dinos and others have already said, question is, how much is safe..
I managed to get 170 BCLK linpack stable with 1,45V QPI using the 8x mem divider. Using 10x I get no boot at 1,45 QPI, so I tried 1,55 and it works. 1,515 again no boot with 10x mem divider, so I'm guessing it won't be stable either with 1,55V. I am not willing to go higher than 1,55 so I backed it down again to 8x mem divider... runs CL7 tho, CAS latency doesn't seem to be too hard on the IMC :up:

I don't think i'm going to go above 1.38v personally, simply as so far there seems to be no need for it to get a 4ghz+ stable setting - currently 1hr into prime blend test for 219bclk on 36x QPI, with 1.38v (might actually need less). Maybe in the future!Quote:

From the description of the Smartfan in GB bios, it seems to do cpu fan only.
edit:
Checked manual, there are 5 fan connectors including cpu fan (plus 1 for NB fan). Only cpu fan and sys_fan2 have speed control, they both have 4 pins, the others have sense but no control and have 3 pins. sys_fan2 is the one at bottom of board beside front panel connectors.
I'd like to use sys_fan2 to bump my 1300rpm fan up to 2000, but the fan connector is only a 3 pin :(
Has anyone successfully ran memtest with 12gb of ram on this board? I am running 12gb of 1600 corsair dominator and memtest won't boot.
Thanks for that. I have this board sitting here in it's box but looks like it may go back as I really like having fan control without using a fan controller. I guess it's the Asus RIIE instead or the Evga x58. I have about an hour to decide. Anyone care to "sway" me either way? :DQuote:

if you havent read BenchZoner's thread about high VTT testing you should......we were being scared into ideas that a CPU will die overnight pretty much with 1.5vTT and BZ stressed the :banana::banana::banana::banana: out of CPUs for months without any ill effects heh....not only did he test VTT but also vcore and PLL :up:
The fear itself is more scare than the actuality of the cpu to go down.
If people run stuff as they do here and seldom get issues, a more common overclocker will rarely have any issues.
I figured out what the issue was. I was running two x-25m ssd's in raid. Memtest wont boot with the raid array active. I turned off my raid, and then ran Memtest. But when I tried to start my array again it failed. Is that supposed to happen?Quote:

awesome man. Benchable?
Can someone confirm that the gigabyte extreme comfortably fits tri gtx 280's? Im looking at getting one, but concerned because i have heard that the board cant seat all 3 cards.
all three fit perfect BUT you need a case with 8 expansion slots.
memtest dont test the ram alone, it also tests the IMC. :yepp:Quote:

I think you can do it with 7, if your case allows it (TJ07 needs a few rivets drilled out to get rid of a wee plate that would block the 3rd card), you'd just need to put a single-slot backplate on the 3rd card, or make it fit some other way - it's not like it has to be perfectly sloted into the backplate space since you're not using the connectors on it.Quote:

Can anyone else confirm that 36x QPI multi actually = 18x? Other boards apparently have x18 multi, my GB extreme with F4j bios has lowest 36x(apart from slow mode), but that puts me on 18x.

Not sure what I am doing wrong here, but I cant get past 175 bclk on my UD5 and 940 to save my life. 175x22 (23 with permaturbo) is rock solid, prime & linpack stable. 180 x 19+, bsods within 5 minutes of prime (getting a lot 0x00000101 and 124s). Current settings are follows, using f4k:
22x175
QPI=36
uncore=13
spd=6
timings are 9-9-9-24 (corsair 1600 rated @7-7-7-10 @1.8v)
LLC=Enabled
Vcore=1.475
QPI/VTT = 1.400

QPIpll= 1.24
IOH Core=1.200
ICH I/O =1.58
ICH Core=1.14

Raising Vcore all the way to 1.55 does not help the bsods at 180+bclck. Any thoughts and suggestions appreciated...
Edit: Turbo and HT are both on...and playing the EIST function didnt seem to help any.
try lowering the uncore to 17 or 16.
what is your ram multi @? should be half or less than half of your uncore. Maybe try 16x uncore and 8x ram
Yep all the tools work for me, vista HP 64. I'm not using Easytune though, i prefer to make change in the bios. Not a great program, anyway.Quote:

It seems like you're not really taking the right approach....at all. I'm going to go out on a limb and say that if you keep your settings where they are, your cpu is going bite it fast.

sorry, uncore is 13x, ram is 6x, the 18 i posted above was when i was playing with memory stuff to see if it was stable at 175 with better timings....when i was on my way up to 175 bclck, 12x uncore would be unstable, 13x just fine (with 6x memory)
I do believe I AM taking the wrong approach, thx Rev...my temps are ok tho, and I'm not near the max Vcore yet, but I really didnt want to run so high on the voltages...I'm on air, hitting 83C on load, 40 on idle...I'm getting 4 GHZ now, I'm trying for 4.2 and I'll be happy ;)
Edit: having issues with my dvd player at the moment, so I am NOT on a clean install...running vista x64, could that be the cause?
I don't think so im also on Vista x64 and running 180mhz bclck without a problem.Quote:

Sometimes you just gotta scrap everything you're doing and "reset" lol. Glad you didn't take my comment as a knock :)Quote:

If you're not worried about ditching your cpu, then by all means...pump it to it lol.
Right now, with HT off I'm trying to dial in 4ghz.
20x200
QPI=36
uncore=16
9-9-9-24 (depends on your ram of course)
LLC=Enabled
Vcore=1.375
QPI/VTT = 1.325
CpuPLL=1.84
QPIpll= 1.24
IOH Core=1.1
ICH I/O =1.58
ICH Core=1.14
Dram=1.66v (depends on your ram of course)
So far, this has netted me 4ghz 1hr prime small/large and blend stable. I refuse to push it beyond an hour at 82C (I'm on air as well) until I can drop it by switching to water (modding my Apogess GT today)
Those settings might not work for your Ise, but they are a bit more realistic to what it should take to get 4ghz.
