do you guys really notice much real world difference, other than benching, between 1600 and 1800 on the mem? I guess if you can go faster for little $ why not, eh? but I was just wondering..
I'm on a true with a delta afb1212she. I think i need to remount it though. I was able to run prime for 24+hrs at those setting and 25 pass of linx. I upgraded my version of real temp to 2.90 and my max has gone up considerably. I also seem to kind of be at an OC wall at this point, so suggestions would be appreciated.
Here is a screen:

I kind of figured as much... and bragging rights. ;)
in other news I finally got around to doing some more OCing... finally! so far so good but I am only like an hour into my prime..
HT off
200x19 (3800)
qpi 36x
mem 8x (1600)
uncore 3200
vcore = 1.300 in bios (w LLC on)
vdimm = 1.60
qpi = 1.360
cpu pll = 1.80
everything else left alone...
load temps, core0 still always 4c over the rest coming in at 62c max while the others are around 58c... not too shabby.. if this survives the night I might try 4ghz next... turning HT off really helped my temps.. wow! I won't miss it as this is 100% a gaming box...
Hai, i want to Buy X58 , and i have 3 option Gigabyte,or maximus extreme or MSI Eclipse
I have Gigabyte P45 and i hate when use RAID, gigabyte first boot is very slow , meanwhile asus very fast (same ICH 9R ? ) and overcloking ASUS very stable, if failed overcloking, setting BIOS not reset (simple)
Now my question is, gigabyte X58 the best in model dan feature, but how about RAID ,is same with P45?and overcloking stability? can run 3,8Ghz 24/7 perfectly? (No cold Boot )
So i very want to hear from user2 who use gigabyte X58. Are You HAPPY Or Dissapointeed With This Mobo ?
Happy, but I don't use RAID anymore.
Happy, but I don't use RAID anymore.]
=================================================
Why? are because slow first boot like i say or RAID controler this mobo dont stable?
Gigabyte have 10 SATA meanwhile RAMPAGE just 7 , i scare if SSD more cpeap and i use 3x RAID, 2 DVD RW , 2 HD data, no place for SSD....
This is weakness of rampage....
Gigabyte x58 extreme can be No1 the best Of x58 board if this issue can fix (RAID and cold boot)
Hey, the Noctua is working great, cooling is about 1-2c better than my TRUE 120. :yepp: Also looks better, build quality is A+, doesnt get better than this, you get 2 fans, 2 very high quality fans, overall the Noctua is a much better deal, better mounting system as well.
Kill your RAID array? (this thread have 73 page) i can read per page :D
So SATA controler Gigabyte for RAID have weakness?
Thanks for your share yukon trooper :up:, this will make me think twice buy gigabyte.... (to bad.. gigabyte have very good model and feature)
So what your opinion for the most stable and durable motherboard for X58? (beside overcloking/ for workstation) rampage extreme? EVGA X58?
Hi Reverend,
I think you are probably dead right - it is just that I have never done watercooling so am a little unsure about doing it. I was thinking of getting the Swiftech H2O-220 Apex Ultima Watercooling Kit - any good.
Just worried about installing etc as water and electronics don't mix too well Lol.
Would you reckon this kit to be ok?
Mark
The Swiftech kit is great, but the rad is a bit lacking for the i7. They use a low profile(allot slimmer than regular) rad and while it does the job, it could be better. You might want to check the W/C forums here and get help with parting up a killer custom job.
As for first time w/c.....everyone has to pass that hurdle. One tip that I have is read up and ask questions as you're doing it. Having an understanding of the entire process is key :)
Unfortunately Hornet, neither of us were talking about the MCR320.
http://www.ncix.com/products/index.p...cture=Swiftech
H2O-220
Now the MCR320 is fine, but it's price according to it's performace...IE not the greatest, and I would take a HL Black Ice EXTREME3-BK rad any day of the weak. Only costs a few bucks more than the MCR320 ;)

i read in the thread that the board does the weird turnon, shut off, post, repost..then boot, this happens after being OC'ed. Is this normal, do most of them do it,im using the ud5. What are the max voltage settings for the qpi/vtt since i've read that 1.35 is the highest voltage in order not to damag the cpu but i cant seem to post at 200bclk with anything less than 1.42..all else is stock settings except the vcore of course. I can't really get any higher than 200 bclk with my ud5 no matter how high i set the qpi/vtt , even if i leave it on auto, any advice on what to do to get over 200 bclk. thanks alot for any assistance.
ok so good to know its ok.. Now why cant i seem to boot at 200bclk withouth using 1.4-1.42 qpi/vtt is this normal, since i see many people making it seem that 1.35 is the max. What can i do to get over 200bclk as i cant seem to be able to boot above that clock speed no matter what i do to votlage. Any particular voltage setting.. ram/uncore multi..?
thanks, ill post a pic of ET6 with all my voltages, other than that im running 200bclkx20, 1600 ram using 8 multi and 16 for the uncore, then 36 multi for the qpi.. I use 1.42 qpi/vtt and all else stock..excecpt vcore whichi requires 1.41 under load and in bios is set to 1.44 which is what the cpu uses during idle processing in windows.
Ok i dont know what happened, i just set my qpi/vtt to 1.24 or whatever is on the picture and everything worked perfectly. I have the performance mode to standard and im running ram @ 1600 with 8X multi and the timings are 8-8-8-24 with 1.5v which is what my ocz gold are rated at.
QPI x36
Uncore X18
Ram x8
Weird i'll try later on posting above 200 and see what happens.
[QUOTE=yomny;3630301]ok so good to know its ok.. Now why cant i seem to boot at 200bclk withouth using 1.4-1.42 qpi/vtt is this normal, since i see many people making it seem that 1.35 is the max./QUOTE]
good question
Funny how things work out. Let's see some linx 20x action :)
These tighten/loosen subtimings just like the performance level settings with the last few Intel chipsets. You absolutely will see a difference but mostly in benchmarks. This is why I use standard for everyday use, and turbo for benching. Extreme mode = lock up city in my experience. Others may have had luck with some dram pull-in adjustments, but not I.
Answered above :)
Indeed Steve and if I recall your build is all kinds of kick ass with a Feser quad xchanger isn't it?
Ok, I got a new 920 with a batch # of 3839A611 and now I'm able to boot up to 211 Bclk, I could not boot past 189 Bclk with my 3839A628. Let's start tweaking. more to follow....
By linx 20X do you mean running 15 or more passes of 17k problems at above 200 bclk.
Before i really wanted to know if i could run 1.42 qpi/vtt without doing any damage.. I was able to boot at 213 and the ram @ 1704.. man Im proud of this ram it was running @ 1650 undervolted.. and now its running @1704 and i set the voltage to 1.64 just to be safe it wouldn't fail.. its rated at 1600 mhz with 1.65 stock.. so far its performing great. So would it be ok to run 1.42 qpi ?? Thanks for the support.
Notice the cpu is not fully Oc'ed i just backed the multi down a bit to test only my NB/QPI, ram.
yomny which batch number do you have on your I 920. Look on the white sticker of the box of your cpu.
Thanks
p.s I'm still waiting on the answer to your question about QPI/vtt higher than 1.35.
3839a628, i was able to post and boot using 213*20 which gave me 4.26 but i needed a bit more than 1.41vcore to be stable and i dont want to push more until i water cool or know for sure if 1.42 qti/vtt is not doing much damage. Keep the info coming guys. Seems to be hard to get a straight answer when it comes to things such as this qti voltage, the max temp for I7 and the max vcore.
There is a straight answer and it's been made clear several hundred times on this site alone lol ;)
Keep the QPI/VTT .05v below cpu vcore, Intels limit is 1.35v VTT and 1.55vcore, but there is a cushion on that figure; mine in practice is 1.45v vtt and 1.6v core. This is water cooled and voltages like this shouldn't be used for long term usage no matter what cooling.
Use my advice at your own risk :)
So i guess then the most people cant really run using 4ghz on a 24/7 setup for a year or two since the required voltages for these are quite on the high end of the safe levels.. Good to know
For 4.2ghz 24/7 I need 1.376vcore load, 1.42 bios and 1.35qpi/vtt. I will be using it 24/7 as long as I have the chip...when i am not benching at higher settings. My guess is most running at 4ghz+ on this forum are doing so long term or as long as they have the chip.
1.35 qpi/vtt is intels max...but some need in low 1.4's range, it is variable per cpu. One person needed crazy high like 1.7, then bought another cpu and only needed 1.3's. Personally, I would have no problem running it in low to mid 1.4's for 4ghz and some are, but just dont need to on mine... each person has to decide on their own risk tolerance.
And DRAM v should be within .5v of qpi/vtt, benching I am keeping mine within about .35.
Benching, between spi 32m, both chess stress test/benchmarks, cinebench, pc mark, etc, I probably have 24hrs+ at prime type loads with 1.96-2v DRAM (to get uncore at 4500mhz and mem at 2000mhz) and 1.62-1.64qpi/vtt, 1.66vcore...cpu still Oces at exact same settings. I wouldnt run these 24/7 or even close to it...but benching I have had no problems with those volts.
how do you get 1.35 for the qpi vtt? my bios only allows changes in .02 intervals on even numbers... 1.340 1.360 1.380 etc..
fyi, my 200x19 config passed with flying colors... so I backed my qpi off to 1.340... (from 1.360)
Hi Steve,
Thanks for the input - gee there is a lot of knowledegable and helpful people on here. I think all things considered I will move to water cooling in the near future because even if I don't want to go for high clocks it will still give me much more flexibility. My system would also be quieter which would also be nice.
Mark
Yeah, maybe GB thought the change represented better accuracy, that would make most sense. Though I thought the variation board to board would be more than .005v.
If asking if I have measured it...no, too lazy to measure or to even look up where to measure:D...have a fluke though. It would be interesting to know how accurate the board is...but knowing I still need 1.355 in bios to be stable regardless of the real value, kinda stifles my curiosity some.
Thanks a mil for this little guide it's been quite helpful, im a bit confused though as to why some cpu's need qpi/vtt higher than others isn't the qpi/vtt a voltage that allows the boards to boot at higher bclk, or is this voltage setting communicating between the board's bclk(fsb) and the vtt of the cpu? sorry for some reason i think qpi is like FSB on previous chips and vtt is cpu termination voltage, normally these two wouldn't be together.
Regardless when i set the qpi/vtt to 1.42 is still in the safe range of the boards settings, guiding myself by the colors where yellow is good, purple is still safe, then red means too darn high. According to this up to 1.46 i think im still in the purple area. When i set the votlage settings to auto the board adjusted to 1.42 qpi to get to 213 bclk but it wouldn't adjust higher than that if i tried a higher bclk.
21 x 191 rock solid
20 x 200 no way
They are both 4GHz... WHY WHY WHY?
yeah, makes no sense, but many have seen same thing.
The stock multis suck for overclocking. Most with i920 report they cant get 20 multi stable or need much more vcore to do so. Many can run 19x211 or 21x191 with much lower vcore than 20x200, if they can even get 20x200 stable. Same with my i940. If using 23 (turbo) or 21 multi I can use roughly 7 notches lower vcore for the same mhz than using the stock 22 multi.
That is assuming in your case it is not also the bclk holding you back...but you could also try 19x211 and see.
I dont think anyone has explained it so that it makes sense ...to me anyways...but no question the issue is there.
Hello !
I tried a lot of things with my i7 920 and EX58-UD5 but it seems I can't boot (the screen never turns on) with BCLK >= 187.
Here are my settings for 20*186 (ok), but 20*187 fails (19*187 too).
QPI x36
Uncore x14
RAM x8
8 8 8 21 1T
LLC : On
VCore : 1,4v
QPI/VTT : 1.36v
IOH : 1.2v
DRAM : 1.64v
QPI PLL : 1.2v
ICH Core : 1.2v
CPU PLL : 1.88v
I tried even higher voltage but it just does not turn the screen on. The only way I found is to set QPI on Slow Mode... Do you think I should try a different setting for something ? Or test something ? I would like to know if the CPU or the Motherboard is the problem...
At the moment, my 24/24 OC is 21*181 (=3.8Ghz) with VCore 1.375v, QPI/VTT 1.34v, Uncore *18 and RAM*8. I already tested my Ram @800Mhz 8 8 8 21 1T 1.64v so I don't think it is the problem.
BIOS : F5g (same thing with F5C or F4e)
Thanks for any advice :)
It is likely your cpu, simply got a low bclk one. I will assume you have a Gigabyte mobo, since you posted here...and ?UD5.
You can try 19x190, raise vcore 1.45v, vtt/qpi to 1.45v, and DRAM on 1.66, try uncore on both 16x and 17x (not 18x), and qpi PLL to 1.18 and just try and boot. My guess is it will fail, or make it to 188 or 190, then fail...your practical limit you have probably already found, just got unlucky with cpu lottery regarding bclk. But you can try those settings just to see. Also can try F3 bios, I know it is not bclk limited, as their are some bioses that are, and I am not familiar with ones you are using...you have diff GB mobo than me.
Soooo... winblows had an update for me this am... well, three, but one of them was for "realtek ethernet" drivers... which promptly broke both my nics... I was able to roll the driver back easily, but wtf? anyone else get and have issues with this update? it was for vista64.
Again one of the reasons I turn off automatic updates and select them myself, in fact my XP64 has never received an update...with Vista it's required
So this is your advice?
Where is the statement of fact from any authority (lets say Intel) pertaining to the highlighted in "bold text" part of your post. I'm not being critical here just curious as to where this actually comes from. I have my vcore at 1.31250v bios LLC on and QPI at 1.32500v for 195 x 20 - 3.9GHz stable.
finally got my cpu to 4ghz stable, 21x191 got me there with 1.392v at 100% load.:clap:
had the same issue with the new update ( and yes i dl them, not on automatic update) thought what the hell, i'll run the updates...and yup...killed my ethernet....i just deleted that and went back to the previous ethernet drivers....
I had a strange crash today. I was playing DOWII and the system locked up. It was running 3.8 GHz stable for a week now.
But after that crash i could not boot anything above stock speeds (CPU MHz)
I think its fragged somehow. I will try to flash the bios to see if that helps but i think something broke down. Max temp where 60c. V-core was 1.35v in bios witch will give 1.28-1.3v load. VTT @ 1.22 nothing special there. Ram voltage 1.64v.
Its eighter the CPU or the board got fragged badly.
Indeed. i was afraid i had killed the cpu or the board somehow. Never had this kind of bios corruption before. One minute its running fine and then it caches like this....
Anyway. Temps are now higher with the F5G bios. V-core seems to be the same. (1.28v) i wonder if the readout if correct. I'm giving 1.35v in the bios. I know board will show lower voltages under load but the difference is quite big.
does is matter what kind of i920 i get or are they all gonna oc the same
I am so frustrated trying to figure out whos values to u, there are so many post with all the bios setting, i am looking for a descent i920 oc to 3.8-4 ghz, on air.
could you guys please guide me choosing setting/tempelate that works and would fit me.
I know what you mean I have read hundreds, if not thousands of posts now trying to figure this all out, but I think the issue is as stated before every chip/MB/Memory is different that is why everyone has different settings. I was able to get to 3.8, (multiple LinX 20 runs and no crashes ever) with the setting in my signature under 3.8. As you can see I am using mostly auto settings and really only changing the multi to 19x, Bclk to 200, Turbo off, and Vcore to 1.33125. Everything else is auto. I hit a real wall trying to get to 4.0 ghz from both a temp and BSD/POST perspective. Only switching to the F5 series Bios made this possible but I am sure I could go higher if I go down the water cooling path as SteveRo did.
Finally got the GTZ block got tired of waiting on dtek, messed with my 920 a little last night...

temps at load??
My mobo is doing weird things...
Turn on and off constantly without posting... and then if post... reset every bios setting... thought it was a corrupted bios... so tried to put other bios versions (f3, f4j, f4m & f5e) but still happen...
Also when it was working... EIST is not working...
http://www.xtremesystems.org/forums/...d.php?t=214437
check this thread. it's got some good info... pretty much you should only need to hard set your memory timings and the only voltages to adjust should be vcore, vdimm, and qpi with the kind of OC you are shooting for.. anyways.. check the settings others posted for the desired clocks you want.
hey guys i am almost done setting up the rig, the threat has gone over a 75 pages. I would really appreciate it if some one could post bios settings which would help me push i920 to around 3.8ghz, i am sure a lot have already been posted, if anyone would be kind enough to link me to a post with good stable bios settings.
I really need the help because i am a complete noob to i7 ocing.
Thank you so much guys, appreciate it.
These first biosīs, F3 & F4 seem very unstable atm!? I have same issues as others have posted. With weird restarts, or for an example: If I cold boot my computer it starts for 2 seconds, then turns off for 2secīs, and then posts and boots? Every time i start the computer it does this. I know it should happen if you put wrong settings and the board resets the settings and behaving this way, but the settings are fine and it never requests new settings or so on?? I really hope someone here can direct me to the best UD5 bios, if not I really hope G-B soon released a better, many better biosīs. As there have only been released two official bios files since release? I mean cmon!? What is going on? And Thx btw in advance for any help!
didja miss my reply to your earlier comment? ;)
this is my config, it's with HT off for cooler temps since I only game on this machine, you might want to leave HT on if you are doing any video encoding or other math heavy stuff
HT off
base clock = 200 x cpu multi = 19 (3800)
qpi = 36x
mem = 8x (1600)
uncore = 3200
vcore = 1.300 in bios (w LLC on)
vdimm = 1.60
qpi = 1.340
cpu pll = 1.80
all other voltages left alone... I hard set my mem timings to 9-9-9-24 1t and disabled pretty much everything in the "advanced cpu settings" area.. these settings may or may not work with your board / cpu / mem but it should help you along the way... if you intend to leave HT on, you'll likely need a little more vcore than I am using.. like 1.325 or so.. maybe higher even.. you'll have to test it out. your mem might like a little more vdimm also.. I see lots of people using 1.66 vdimm, but I didn't need to run mine that high.. ymmv
good luck!
you guys are freaking so awesome man, i mean i just freaking love you guys. I will apply the settings as soon as I get the memory. thanks again doggies.
how f5g working out
I have a new toy to play with over the coming weeks.
Need to insulate the mobo and cpu first, planning on going subambient, at least for testing.
Flat out and sweating I expect the boreas to get cpu temps down close to single digit C at idle and ??? at load.
I will probably start a new thread over in the tec cooling forum, first pics :) -
SteveRo, interested to see what it will do for your clocks and vcore requirement, keep us posted.
I have been on F5f bios for extreme since last night....all memory secondary timings for my memory are same as F5e, vcore requirement for 4.2 is same, same stability on prime, dont see any noticeable cosmetic differences. I can only assume some bug fixes, dont know about any resume fix since my computer never sleeps, just the monitor, but it works as well as F5e did, so will keep it on mine.
haha SteveRo that is really nice, I can't wait to see the results.
How do I flash my bios without a floppy with Qflash? I've tried it and will not detect my usb stick.
anyone ?
thanks
You need to make it botable
I am now testing the UD5 with Raid 0. I am using PCMark05's "XP Startup" as a bench. With MFT.
Intel ICH10R:
XP - 4200 MB/s
Vista x64 - 2200 MB/s
Gigabyte Raid
Vista x64 - 126 MB/s
I asume MFT doesn't work on GB's solution, but even then the scores are crap for a ramdisk (acard 9010).
Is the GB solution really so bad?
Cool it's stuff isnt that good. That one in the picture didnt get good reviews.
maxpc and canucks both rated it well - see -

and
http://www.hardwarecanucks.com/forum...review-17.html
So is anyone using the AHCI for their drives, or is it not worthwhile? I have had it both ways, not sure there is really any performance bonus to speak of. I know that the AHCI bios detecting drives BS is getting on my nerves, why the hell can't it remember what drives are connected instead of making my boot time 15 sec longer :mad:
I haven't had a lot of time to play around, 180x20 went pretty smooth, but getting to 190 has been a mass of BSODs. I've never seen this many blue screens trying to tune a board. On all my other boards the stress testing app would let me know there was an error, this board just gives a BSOD or reboots itself :( It's kind of frustrating, tuning is a lot harder when the machine hides information from you. Maybe I am having more trouble since I am using 6GB with HT still turned on, it seems a lot of folks are only running 3GB.
