im gonna keep it around for a bit longer and see if MSI will release a proper bios for it. If not then im gonna hit up the EVGA board.

im gonna keep it around for a bit longer and see if MSI will release a proper bios for it. If not then im gonna hit up the EVGA board.
I just flashed my Rampage II Extreme to 0903 Official. It's up on the Asus site. Again, that is an official BIOS. I'll post about in the RIIE thread also, but wanted to make sure people saw it in case they didn't have it yet.
Well, I finally figured out this i7 thing, ha. It helped when I finally got the math right on my memory. I was trying to run my memory at ridiculous speeds with ridiculous timings (new to the whole DDR3 thing.) :)
So, I've settled on 4.0GHz (211x19x) HT ON @ 1.375 VCore - 4+ hours with simultaneous LinX + Prime is good enough for me. My biggest issue getting stable was the memory timings / speed part of it.
I can't believe the difference in my rendering times between my daul core and this 8 "core" i7... WOW. I went from a 4.4GHz E8600 to a 4.0GHz i7 w/HT and my bench render went from 6m 6s to 2m 2s!!
That's HUGE. Money well spent! Very happy. Now I'm back in the "in" crowd, haha.
Nice ! What batch # ?Quote:

These things seriously are Monsters! Nothing will compare to them. If you are running 4GHz you have more power than a QX9770 at over 5GHz. With the HT it's even more. Wait until you try some video stuff. These CPU's were definitely not hype. In fact, I don't think many except for us types that have tested with stuff even realize how powerful these things really are.Quote:

When i get water on mine I'm gonna see what 4.2GHz is like.
I sure hope the game devs got with the prgram early on, because when they get optimized titles for these CPU's out there is gonna be some amazing stuff happening. After I get my water on, I plan to test MSFS alot more at these higher clocks I'm running now. It uses the CPU alot more so I want to get my water going. I'm ordering the rest of my stuff tomorrow.
Well, Ive managed to get 3.8ghz @ 1.22v stable out of this thing. I disabled HT for this and have my RAM running at only 1080mhz 6-6-6-17 or so for now.
I noticed there was a setting in BIOS another PLL I did not touch when trying to OC this thing before... QPI PLL stock its 1.1v Ive raised it to 1.16v is this a setting you guys are changing at all?
I have my QPI set to 1.33v running this @ 181/x21 for 3801mhz.... Stable 45min prime95 (way further than it has gone before)
Surprisingly, I messed with different uncore multipliers and having it any lower than QPI does not seem to help stability, so I am running uncore @ same speed QPI bus is at and its just as stable so far...
Max temps have hit 80C so, Im not sure if I wll enable HT from this point or not, knowing it generally makes processor hotter and is known to slow down gaming (primary function of this computer)

But yeah, this i7 is pretty awesome. Now I just need some SSD action...
Some early results for 920 #3836B043 on stock cooler. This chip needs around 1.15v for 21x170bclk with HT enabled, temperatures hit 75C @70F ambient with prime95. I think I'll stop at this, need better cooling
Let us know how it goes, I and derektm have that same chip and having problems with it doing anything decent. What board you using?Quote:

Well I grabbed another 920 today, the batch # was close to a couple of decent ones on here. 3837A908 seems to be a lot more playful than the last one. First thing I noticed was the default vcore, 1.275v vs. 1.325v of my other one. I did the basic setting in the bios, left turbo and HT on, booted right into windows and started priming at 1.232 under load at 3780, lasted about 2 minutes then rebooted. Turned off turbo, and it's about 10 minutes into prime as I type this. Temps are 54-60c in a 22c ambient, VTT is at 1.15v, but it looks good so far. There's one more of these at another retailer across town, for those in Winnipeg, pm me and I'll give you the location.
edit: actualy it's going between 1.232 and 1.216v under load with LLC enabled, I think I'll do the vdroop mod that dinos22 mentioned.
http://valid.canardpc.com/show_oc.php?id=487878
question, should I or should I not have LLC enabled for this chip?
Also, my BIOS has a setting called performance mode and options are: standard, turbo, extreme the last one I think is that I know its something greater than turbo....But, gigabyte is not to clear about what this setting actually is. Anyone have any ideas?
Its not intels turbo either.
I would disagree. It does 3.6ghz with very little tweaking, at 1.15v set in bios and with stock cooler it stays under 75C. I can't push it more since I don't have a good cooler (damn D-tek still hasn't come out with 1366 bracket). You might be right for the chips in your possession but they are not always equal ;)Quote:

I am still under the 1.2815v default vcore for 3.8ghz =) Im at around 1.23v or so...
Somebody said something about Dtek having a supplier issue. That's just a rumor though and I did not hear that directly from them, so take it for what it's worth. I hope they get that issue sorted soon. I'm gonna have to buy the GTZ block tomorrow because they didn't come through on the hardware. I was gonna buy the DTek fusion. If they don't get that thing out soon they're gonna loose all their sales. I know a bunch of people that have jumped ship already. They even had a thread specifficly about that, and there were like 30 or 40 people in that thread that replied they went and bought a GTZ...even people that had DTek blocks already. They *need* to get those Pro mounts out *now*. It was announced those thing would be out shortly after release. We're over 2 months after release now.Quote:

I know how you feel though. I've been waiting on stuff trying to get it on one order for months now, but the wait is over. I'm gonna get what I can tomorrow, and whatever is not in stock I'm gonna have to order somewhere else. I must get my machine under water and get it in the case. I have an office that is a mess in this house, and I wanna get rid of the clutter.
3841A is a very good batch (i'ts actually my second choice in what i want to pick). Don't be so sure of the superiority of the older B ones.Quote:

And this time the run was even better when the CPU multi on x21 than x19 :up:
Right now I topped at about 210 Bclk, x10DRAM/x20Uncore, 1.65v QPI/1.80v Dram and 21x CPU with Turbo and HT=on.
It was unstable for SuperPi32M but I managed to Pull SuperPi8M and wprime 1024M.
If I could just hit 215 bClk with the same multies and run SuperPi32M I bet I can go sub 8M :rolleyes:
Too bad those ram just don't like anything above 1.8v !, this is the sweet spot for these sticks.
Bottom line, A crappy ram can also be a burden on your IMC so try to use different ram and see if its your IMC or just bad ram.
For i7 it's alll in the ram :yepp::)Quote:

hey i might actually get a reply here, as tweaktown is pretty useless for X58 related stuff...
Hey, get this "BF" error code on my motherboard when i try for 200BCLK on my board...does so even @ 190...barely does 185BCLK...
Board is Gigabyte X58-UD5.
Just wondering if someone can give me a reason it is coming up?
BF error i know is floppy controller (but i have it disabled in bios)
If someone can help me solve this problem...it would be greatly appreciated.
It doesn't power cycle with BF it just hangs until i reset.
Cheers.
I'm planning to switch to i7 but there are still some things I don't understand. Could anybody give an answer on my following questions:
- What could be max. OC when I want RAM to run at least at 1600Mhz? Are there RAM multipliers or something? How can one calculate the RAM speed when you know blck speed?
- What is max. temp. these CPU's are allowed to run at?
- Is there a good OC guide available on the net to come to a better understanding of the new bios terms and there relations?
- Is the P6T Deluxe board mature enough (e.g. bios) to use with i7?
Thanks in advance.
PS For all the D-tek Fuzion version 1 users:
See this thread for custom made brackets.
- For running Ram at 1600 Mhz I like 200 bClk and CPU x21 (Dram x8) so it runs on 4200 Mhz. its a great 24/7 configuration if you can cool the chip.
There are various multipliers (QPI/Dram/Uncore/CPU) to work with, some are locked, some are open downwards and some are free, you do have Dram Multiplier however.
ram speed is calculated in the following way: "bclk x memory multiplier=Memory speed".
- Max temp for i7 is 100c degrees, buy you better stay below 90c degrees for daily use.
- I think dejanh's (a member here in XS) guides are quite nice for starters, try this this and that.
- The Asus P6T Deluxe is a great M/B though currently it has an issue with the turbo which scales down(x20/x20.5 CPU multy) when you hit high temps.
I would wait for the DFI motherboard If I was in your place, it looks like a great M/B to me.
I'm soon going to change too. I'm just wondering if a GTX240 will be enough to cool it OC'ed. :P
I would suggest a triple as mandatory for i7, or you will have to settle for moderate OC and high temps.
Is a Quad Rad overkill?
definitely not.
These i7 run hot like hell, believe me, I own one.
I already have the project built with a dual what about adding an extra instead of replacing the dual? Like a triple or another dual...
A dual rad can cool the CPU but it depends on the goal you are trying to achieve.
What speed ? what temps ?
You would probably get 4Ghz at about 80c degrees max.
It also depends on your fans, configuration, block and ambient temp.
Adding another dual is an option but a bit messy IMO, I like solid stuff :p:
No, I'm running a triple and a double rad.Quote:

So, for those on the fence about lapping their CPU for air cooling, I wouldn't - just lap the HSF.
My block is an Apogee GTZ, MCP655, Silverstone's FM121. CPU Loop only.
My objective is as much as i can get.
I've been studying i'm thinking of keeping the 2x 240 rads for my SLI setup (thinking 2x GTX285) and will put a triple for the CPU on top with push pull config. FM121's too. :D
A friend of mine is running 2 Triple rads (TC120.3+MCR320) with 6 fans (fans/rad/fans/rad) and his temps are about like what I get.Quote:

I'm doing it so I can't see why not.Quote:

A decent enough air cooler although I found the fan to be a little weak. Easily replaced with one that has sufficient pressure to handle moderate oc's with an i7.

Funny, everything on AUTO offers me the best results. I tried messing for hours upon hours with PLL and especially QPI voltages, all would break stability. Also, I would disable HT and go for raw clock speed, except I need the 4 other "cores" for rendering purposes.
Full load after hours of Prime+LinX gets my lapped TRUE Black to around 87/88 degrees C. I'm fine with that. We'll see if these i7's degrade, or "burn-in" at all...
And S3 resume (sleep resume) doesn't wake the vid-card up... just black screen. That SUCKS - I rely heavily on using sleep functionality in Vx64.
Sorry to re-post the data but I wanted to draw some conclusions from it:
Looks like you need at least 3400mhz uncore to not hold back the cores at 4.0ghz.Code:Ubuntu Desktop 2.6.27-9-generic SMP x64, compiling kernel version 2.6.28.1

Going from 3200mhz to 3400mhz uncore @ 3.8ghz is a small gain but it seems more stable on my system so I'm using it.
Uncore gains @ 4.2ghz are relatively small so feel free leaving it low to be stable.
Well, after some time fiddling with the FZE I got some results...nothing that I go "wow" at really, but ok I guess. It shaves off about 7C compared to the TRUE at 100% fan, and about 4C at 60% fan (comparable noise to TRUE).
Testing with my low-voltage 3.8GHz OC using QPI:Uncore in 1:1 (3.6GHz each)...
Nice idles at 25C, but load is not so good. I am expecting load in the mid 50s for this clock, but I am peaking out at 61C using two instances of LinX. The temps are part of the second 20-run (I did one 20-run first to warm everything up).
Anyway, here it is...oh and, there is a slight chance that 2-3/6 of my TECs are not working correctly, so I am RMAing this baby later in the week and will be doing more testing with the replacement unit. I did the "low" idle test and the coolant temp could not drop below ambient (23C) even with TECs and fan at 100% for an extended period of time. Definitely no condensation or anything which indicates a problem with TECs. They should get very cold if working properly according to Coolit, like not ice-cube cold, but very cold-water cold (between 7C and 12C).

^^^amazing, great job :D
With these gigabyte boards, I have a question. There are 2 entries in BIOS that say CPU clock drive and PCIE clock drive, both have options of 700mv 800mv 900mv 1000mv ... what are these exactly and should I be paying attention to these for stability increase when oc'n the cpu? Stock I think they are set to 700mv

Think maybe this happens because its putting more stress on the IMC.

I will do Prime blend next and then go cry in a corner when it BSODs.
Same experience / result here. After a lot of trial and error I ended up with same settings as you... A coincidence? Thinking of replacing MOBO with Blood rage or EVGA X58 Sli or DFIQuote:

I have a gigabyte board...
On Auto i do believe that boards try to compensate, as you say, i never leave many things in Auto :D Have also heard some horror stories over the years... Auto vcore:hitself:
yeah thats one I dont wanna let it set at auto =) I know what your talkin about, especially like with all the factory oc profiles on some older boards...wheww smoke that cpu! lol
But, Im wondering if I should just leave all them at auto cept vcore...see what it sets the qpi/vtt and pll's at...hrm wonder if it would overvolt them too far as well..
Edit UPDATE about my 3836B guys it seems this chip in particular does not like the uncore multplier being anything below more than 2 multis of the QPI bus. If I do that I get the uncorrectable hardware error almost guarunteed. If I have uncore within 2 multis of QPI bus...its stable and does not BSOD. This seems to not matter what my RAM is set to either. So, I think this is very interesting =)
Obviously I don't think any of us would ever let VCore, VDIMM or MCH-type setiings remain on AUTO, however, I have found ASUS does a real good job with voltages on the rest. Now if I were using extreme cooling at extreme speeds, obviously this wouldn't be a discussion (every single setting would be manual).
Manual settings doesn't help here as I have a single stager built into my Lian Li case but anything else than Auto set in BIOS results in instability or a no post. I ended up with same BIOS setup as you after much trial and error and it's the only thing that works, even with -50 degrees Celsius 24/7... :confused:Quote:

Edit: Correction: I'm using 1.395 VTT instead of 1.375 which I used with 2 modules. I'm also using 1.68v DRAM instead of 1.66v.
I got it from Newegg if that's of any help.Quote:

Would anyone have an idea why EasyTune6 wont run on my PC? I have vista...when I install the program and then reboot PC, I double click icon and then nothing happens. I look in task manager and there is no exe or anything...it just seemingly starts and then exits.
Anyone know what may be causing this?
Thanks
I get that problem sometimes. It usually doesn't start upon boot either. Sometimes I run it twice before the tray icon appears. I also get a 'has found latest version' popup box every time it starts or tries to start.Quote:

Well, nothing EVER pops up for me...like the latest version or anything or tray icon. only other programs I use for monitoring are speedfan on startup and rivatuner for video card, tried exiting both of those then starting ET6 and same thing happens =(Quote:

Temperature varies a little bit but after 2 hours of BF2 gaming it's down to 44-45 degrees as opposed to 48-49 on an ordinary basis with my i7 965. It was custom built by Overklokk, a Norwegian OC'er, that was pretty active at XS until a couple of years ago, but then retired... Guess you still can find a lot of his posts / results here somewhere. CPU is given 1,475v in BIOS, effectively 1,465v.Quote:

Running 4.45GHZ (165 * 27) with 1,45v with HT enabled 24/7 but has never tried BOINC or anything similar in paralell with gaming... :p:Quote:

Yep, I know. I'm going to try and see if it's still stable with it lowered next. I needed it to get stable even at lower overclocks with these 2 gig modules. I need some 1 giggers like yours so I can cheat. :PQuote:

So if you are running 1.9v on your memory you need at least 1.4v QPI/VTT (probably more lke 1.5v) and this is 'safe' with sufficient motherboard cooling, I think.
So far I am unable to get stable at all ever with 3 x 2gig modules at tight timings at 4.0ghz and beyond without exceeding 1.35v QPI/VTT. Actually, I needed 1.375v QPI/VTT to pass long prime blend runs even with 2 sticks.
Thank you - Im back on track again. My issue seemed to be memory timings and not vcore of QPI volts.Quote:

I have managed to get memory timings working at 8-8-8-24 at 839Mhz, 3356.1Mhz once I increased the write delay timing out to 15 from auto.
This has increased my stability no end and is possibly due to apps like Linx and prime writing a hell of a lot to RAM.
It might be worth you having a play and see if yu can get the extra memory bandwidth which might just give you a bit extra for your money.
Im running Corsair DDR3 1600Mhz dominators at 1.65v
thanks again for your pointers, much appreciated.
great thread everyone - Im loving thi i7 platform although it isn't as easy to overclock at 4ghz as I had heard!
Ian
Wow, that's awesome man.Quote:

Viking,
Which setting is that? Write to write, or write to read?
Having troubles getting to 4ghz myself on RE2 board:(
Thanks in advance.
Lou.

When fiddling I must have switched the DRAM timing mode from 1T to AUTO which means it switched by default to 2T mode, presumably this reduced memory efficiency also?
I just benched it quickly with Everest memory bandwidth test and its still clocking at 18100MB/s so still not too shabby......
Its been running prime95 (blend) and a 100 pass Linx pass (10000) for 1hr now and has been stable at those settings.
Edit: A quick google showed a fair few disagreements regarding memory performance at 1T vs 2T so I need to do some more investigations too.
Hope I didnt get everyones hopes up and apologise for any wrong path leading.....
What is the literal name of this value in MemSet or the BIOS?Quote:
