Anyone done this compare with 3dvantage yet?
Yep and I got an 1100 overall score better with HT on.Quote:

I score considerably less with HT Disabled on 06, and vantage. My best scores come with HT enabled on either one, at least with my setup.
played today a little bit with my good old Micron D9JNL :D

@ Chri$ch
Thats a great overclock on the CPU, but the clock on the RAM is awesome, great job:up:
@ Chri$ch
nice ;)
QPI/VTT Voltage please :D
hehe, thx :)
vtt is ~1.55v for DDR3-2000 CL8 and ~1.65v for DDR3-2244 CL9
i think the memory can do more, but the limit is the UCLK freq. :(
My best 3Dmark06 to date, this with HT off and with oc'ed 9800GX2 -
Good job so far, here's something i seen from Fugger on Saaya's 101 thread that might be of assistance:Quote:

If I can game for 10 hours straight, and I can run 60 different benchmarks without a single hiccup(#4 air cooled Vantage/GTX260 on the planet ;) ) Then I call it stable. I fold with other, cheaper machines that I don't give a rats ass about.
Then that's your experience and your opinion and you're entitled to it :up:Quote:

About prime, Blend really is the option to go for, small FFT loads data of a size that fits in the cache on the cpu and not so much your ram, which is why it traditionally produced hotter cpu (penryn and previous), this was mistaken by alot of people as being more stressfull but it's not, it's just a hotter cpu because the l1/l2 cache is being used more. Large FFT will utilize the memory and therefore memory controller, so for i7 this stresses the cpu more because the memory controller is located on the Uncore with the L3 cache. That's why large FFT is making cpu's hotter compared to small FFT, relative to how it used to be with penryn.
Blend just covers all the bases, good luck with Linpack though. I might run intel burn test once i have my final OC down, out of curiosity. I done this on my QX9650 and it failed where i was 30hr+ blend stable. I ignored it and never once had a crash/BSOD after. Up to each person themselves i guess.
maybe i should just drop my voltages down then so that im just game stable to then :shrug: and not bother folding with this rig
but i really dont want to push qpi/vtt v more than 1.45v till we know what is safe for 24/7 use, i might just put it on 4.1ghz prime stable* for now, and wait till we know more
The great thing about the i7 is that less is more. Settle for a lower clock for folding and it'll still pump out better than average ppd.Quote:

great work eva :toast: i have the same dfi board comming from germany later on next week(hopefully?) with a tri dominator set.:D
im curious what is the highest Base Clock you've been able to achieve one this board ??
wow you got 2000MHz ram withing the safe spec of intel: 1.35V QPI!
How come?
dual channel maybe?Quote:

Yeah it's dual channel but for single threaded apps you can lower CPU VTT volts as opposed to multi-threaded loads like prime95/hyper pi..
for Prime95 with TRUE120 air - room temp 29-30C

eva2000 do you mind sharing voltages for that run?
cpu = 1.25v bios
mem = 1.68v bios
cpu vtt = 1.44v bios
Seems Uncore clock is the secret to high bandwidth, feed it with vdimm and watch your scores go up!

Yeah... It seems uclk is fed by vdimm rather than VTT/QPI, so you can keep VTT low as long as you're not pushing bclk higher. This also dispels that stuff about needing 8:9 / uncore higher than QPI being unstable, i'm totally stable and much higher right now :yepp:Quote:

When folks calibrate real temp, what are are you coming up with, mine looks like -5C to get to room temp +7F for 77F - see -
http://www.techpowerup.com/realtemp/docs.php
Also - looks like a CANNOT get 4.2 with ht on - on air (thinking about a boreas!) -
i'm having issues running 3dmark so ill see if I can get it working, but for now its been stable for a few hours of benching, Generic CPU bench, WPRIME, etc
http://img.techpowerup.org/081227/Capture011.jpg
I would not calibrate real temp with core i7's, tjmax is read from cpu, and most temps seems to be pretty reasonable from idle to load. But if you do calibrate idle, it is 7C plus ambient in C at idle, undervolted, underclocked state, and that is for duo/quad, no one has tried calibrating for core i7 yet.Quote:

rge - yep, under volted, underclock, based on the directions (granted for pre i7) real temp was showing 5C over what it should have been.
This should only matter pre 60C based on the directions - http://www.techpowerup.com/realtemp/docs.php
"Calibration
Using this knowledge and some more measurements, I came up with some simple correction factors to help compensate for errors in the DTS at idle. Using an Idle calibration setting in Real Temp of (-2) for my E8400 and using a setting of (+2) for my E6400 now gives me very accurate temperatures for both processors from 10ºC to 100ºC. Typically within 1ºC or 2ºC of what an IR thermometer shows near idle when pointed at the bare core and exactly equal higher up. The formulas were designed to bring the above two processors a lot more in line with each other which they should be, given the identical core voltage. Power or heat generation is proportional to the square of voltage so that is the most important factor to equalize when making comparisons like this.
If you want accurate idle temperatures then you need to calibrate Real Temp to your processor. Avoid changing the default TjMax that RealTemp uses.
The first thing to determine is if your processor reads too high or too low at idle. My method involves reducing the heat output of your processor to a minimum. You do this by lowering the clock frequency (MHz) your processor runs at as well as the core voltage. It's also important to run your CPU fan at its maximum speed. I like to go into the BIOS and set the front side bus speed to 266 MHz and then I set the multiplier to 6.0 which results in an overall speed of approximately 1600 MHz. I also lower the core voltage as low as it will go. My ASUS motherboard goes as low as 1.08 volts which is fine for this test. You can also accomplish the same thing by enabling SpeedStep and C1E in the bios. Start up your computer and use a program like CPU-Z to verify that it is running at approximately 1600 MHz and 1.10 volts when sitting idle at the Desktop.
By reducing your processor's heat output down to a common fixed value, I've found that a well air cooled Dual Core processor will idle at approximately 4ºC to 5ºC above room temperature when the computer case is open. Quad Core processors will idle at 6ºC to 7ºC higher than your room temperature. If your reported temperatures during this test are less than your room temperature then you need to open up the RealTemp Settings window and enter a positive Idle Calibration factor to boost them up into a more believable range. If your CPU is like my E8400 and you notice reported temperatures that are higher than 5ºC above your room temperature at idle, then you'll need to use a negative Idle Calibration factor to bring your temperatures down. In a Dual or Quad Core processor, the temperatures reported during this test should be equal across all of the individual cores.
That's all there is to it. As long as TjMax is chosen correctly and you do a simple calibration, your reported core temperatures will be very accurate and comparable to other users who are using the same software and have also individually calibrated their processor. This is not an exact science. It's just a way to compensate for a DTS sensor that was never designed or calibrated by Intel to report accurate idle temperatures.
Though this test is done when your processor is idle, the calibration settings entered will improve the accuracy of your reported tempertures up to approximately 60C. At this point and higher, most digital thermal sensors are very accurate and no further correction is necessary"
Yep the calibration for realtemp was based partly on some of my testing with drilling hole through IHS and then into die and measuring with thermocouple vs software reading. And yep the calibration cuts out around 60C, it is just for idle. But given the core i7s seem to idle at reasonable temps, so far I dont think any calibration is necessary, or at least not like other 65nm or 45nm core duos.
On water I am idling at 8C above ambient, which is probably pretty close to the truth for 6.75W per everest. I would expect on air for you to be a few C higher at that higher watts. But load default settings in bios, then enable C3/C6/C7 deeper sleep states and disable HT, I went down to 2W according to everest, and my temps were then 7C above ambient. I just put pic in realtemp thread of mine at both temps. The spread between water and air is going to increase as watts increase and should decrease as watts decrease, so if you are 12C above ambient, you might come down to 10C above or so. Also make sure your fan is on high when you do the test, and you turn your computer off for about 15 mins or use a fan to blow the internal case temps down to ambient, b/c calibration is with open case.
Had not thought about checking idle temps out with i7, but it is interesting that given similar watts output, it is showing same as I saw with diff cpu, otherwise using similar cooling/setup.
http://www.xtremesystems.org/forums/...35#post3530235,
last post
rge - if I understand you right - @ idle - real temp is showing approx 7C higher than it should for your set up?
By the way, thanks for all the help - unclewebb and yourself - re - real temp - a great app!
No, real temp is reading exactly as it should on mine without calibration. It is Unclewebbs app, I am one of his guinea pigs:DQuote:

Core i7 with HT off is also reading about 7C above ambient with basically same cooling system and same watts.
So what I am saying is core sensors seem to be accurate on my i7, and thus realtemp seems to be accurate, and is reading exactly what it should at idle, without calibration.
You probably should be idling at 9-10C above ambient with your air, and my guess is if you had case open so internal case ambients = ambients, and you turn HT off and enable c5/etc, and turn cpu fan on high, your temps would be accurate, and again no need for calibation.
vge - very good I will test again - last time I had c1 enabled and not the others, this time I will enable all the c's, turn off HT, turn blockxmulti to lowest and let it sit for a bit and see what I get. My computer closet is probably a bit higher than the rest of my basement - even with the door open - probably - 68f or so.
max on water :)

Ambient room temp is approx 68F - 20C.
Real temp reads out: 29-29-30-34.
So - reported temps are 9-9-10-14 over room temp.
So I should enter (-) #'s into the idle calabration set up - but how much?
Should I go the full - 9-9-10-14? I was going to set -5 for all 4 calibration values.
Your reported temps if accurate SHOULD be 9-10C over ambient as I stated previously.Quote:

On water, I idle 7-8C above ambient, you on air 9-10C over ambient.
You seem to want to calibrate your temps to near ambient. There is a gradient of about 5C from core to IHS, and another 2-3C from IHS to ambient. So you cant be lower than ~7-8C over ambient using air or water. You can with inaccurate sensors, but not with more accurate ones as the i7's seem to have.
very good understood, I will leave idle calibration at 0.
Question guys.
My CPU ambient temperature is now at default settings 27ºc, but im getting readings of 42/37/42/38 < per core. Should I calibrate it? Seem to be off on cores 1 and 3, but 2 and 4 are about right with a 10ºc difference. What do you guys think?
My eVGA X58 has this strange idea that QPI 150 means QPI 14. Fourteen, no missing zero - and it then tries (and of course, hangs) at 280 mhz. Stupid piece of crap.
Chicken Patty - I assume you are using real temp?
Did you set cpu to lowest power consumption level with max cooling?
How long did you leave the machine run before you took your readings?
What was the room ambient temp?
naw I have not done that, I was actually just reading back through a few posts and saw that myself, going to do that in the morning and i'll post back. Thanks.Quote:

I'm wondering what kind of uncore clocks everyone is hitting and at what volts? Right now I've got uncore @ 3047MHz w/ 1.325V and it is stable.
Which motherboard are you running Extelleron? Thanks.Quote:

thats what im using for 24/7 with Speedstep & C1EQuote:

(X58-UD5 with F4K or F4R bios )
a friend mine also bought 3 days ago a core i7 920 , Gigabyte DS4 and Corsair XMS3 1600 and couldnt run 8-8-8 or 7-7-7 with new F4 oficial bios , i said to flash with F4K Beta bios and voiláaa 1600mhz @ 8-8-8 or 7-7-7
So Try another Bios !!
Btw: for what iv seen , maybe the best X58 Mobo/Bioses from Gigabyte is the UD5 (not the extreme)
regards
That would mean going to a more recent one which i'm unwilling to do, after the problems it has caused other people in the giga thread :rolleyes: I'm not too bothered i have more bandwidth than i know what to do with @ 1600mhz and 4ghz uclk.Quote:

Apparently, on your board its called QPI PLL. I would have assumed it to be QPI VTT, but +300 isn't a voltage.Quote:

mascaras, can you list the subtimings and channel A timings for bios you are using for UD5. I cant run my ram at 1800 either, 1770 max so far. pic shows timings on mine I am interested in, I am using F4m bios but with F4j memory timings manually entered (F4j mem more stable than f4m), but want to try some other timings. (prefer other things in f4m)
Just interested in 1800+ in terms of benching.
yeah sorry I forgot to put mV. and thanks for clearing this up for me too!:up:Quote:

Anyone know what it does on my board?
that I know off there is no auto setting, you can just leave it on +0. I had it set to what you saw, but those settings were taken of the guide over at the EVGA forums and just kinda tweaked a bit for my rig, but really dont know if it helps or not with o/c'ing. Right now i put the rig since yesterday at default settings and i'm working on an overclock of my own. Now that I am much more familiar with certain terms and have learned much more about this x58 architecture i will overclock from scratch. So i'll make sure I post some results when I have them. :up:Quote:

I was able to run my RAM same as yours but mine is the 1333 one. 8-8-8-19-24. what voltage your feeding your RAM? Also i think if the QPi/Dram voltage is on auto, it'll automaticaly adjust the dram voltage to keep it within the guidelines. Not sure exactly how that works, but I read that somewhere in this thread. Maybe once it adjusts your ram is not getting enough juice. My EVGA board has a in windows overclocking/monitoring utility and you can see it drop from 1.65v to 1.4v. But for some reason, when I set it from the BIOS it does not do it :confused:Quote:

Edit: well not sure if loosening up subtimings (just standard instead turbo,nothing manual yet, or trying uncore 21 instead 20 or using F4m bios with f4j manual channel timings, or fact that i forgot change main timings to 9,9,9 but booted up fine 1800 8,8,8 with 1.68v dram:shrug: had tried for hours before and no luck
Are you sure about your contact between the cpu/hs ? I am using 1.45v (bios) 1.408v-1.392v under load, no HT, and the highest I've seen is 76c on one core, the rest are around 70c. This is with HT disabled. I only use this to burn DVD's and game occasionaly, so those temps are from prime95 x4 (stable for 2hrs +) in a room temp of 25-26c, case on (Coolermaster Centurion 590) Either HT adds that much heat, or it's the humidity in your area, or the contact of the HS ? It would be interesting to put a DMM on each of our mobos to see if we are getting the actual voltage reported ! Not sure what my max o-clock is with HT on, but I may try later tonight. I also want to throw in another HD and try Vista x64, so not sure if I'll have time.Quote:

I really think its my mem that's holding me back from 4.3-4.4 stable.
i havent really done my research on RAM for the i7, but whats some good tri channel RAM to recommend to someone?Quote:

I'm surprised how easy it was to achieve a new personal best dual channel DDR3 max frequency of DDR3-2200Mhz at just 1.965v bios set vdimm :)
Seems with 16x memory multiplier, both Memset 4.0 Beta2 and CPU Tweaker tool can't report the right memory clock frequency. Had no problems with 14x memory multiplier.
Vcore = 1.05v
DRAM Voltage = 1.965v
CPU VTT = 1.48v + 0.075v

I have a strange feeling these are going to be fantastic (and expensive) for OC'ing... The numbers posted alone :shocked:

If you're running Vista you might not be happy with only 2GB. To bad they don't have these available in a triple channel and at the same cost.
THanks bro, im gonna go check out those PI Blacks and see what the deal with those is...Quote:

Initial notes, findings and tips
What's up with your guys' DRAM? I am running the exact quantity of that exact DRAM on R2E at 1603MHz in BIOS with 7-8-7-20-1T timings completly stable with only 1.30000V QPI/DRAM (VTT) and 1.57731V DRAM.Quote:

This was completly stable and I am sure I could have tightened the timings and voltages a bit too, I just never tried it...
Hi dejanh,Quote:

Firstly, I have the same board and RAM as you, but My i7 920 seems to hit a brick wall @ 3.8GHz (19X200 multi). It will prime (small FFTs) 24/7 with only 1.3v Vcore, 1.89542v PLL, 1.3v QPI/DRAM, 3600 QPI, 3200 Uncore and HT on. However, anything above that causes my PC to BSOD when running prime. I have tried up to 1.52v Vcore and various other settings. Closest I can get is 4.0GHz, 1.45v Vcore & HT off.
I have a decent water cooling setup by the way, temps don't go above 65c @ 3.8GHz 1.3v, 75c @ 4.0GHz 1.45v. NB/SB are quite warm @ 55c though (stock cooling only).
http://img227.imageshack.us/img227/782/p1000558pe2.jpg
Also my PC won't even post if I change my RAM timings below 8,8,8,24,1T @ 1600MHz (1.65v). 1800MHz the same even @ CAS9 & 1.7v?
Did not think 4.0 GHz with HT enabled would be so challenging, perhaps I just have a poor chip?
try enabling HT and see where your temps go. ;) HT adds ~10-15°C, plus you need to increase Vcore to get the same clock stable. :yepp:Quote:
