1.225 is what mine uses for 4.05. Its almost stable at 1.2v and that actually may be work with lower temps.Quote:

Agreed. Less than 1.3V for 4GHz is quite good and most will not get this. Steve, go check out my pics in the competition thread :p:Quote:

I think I got a dud somehow. I dont know if its the MOBO or the CPU, but I cant seem to get it going.
Im stuck at 180-181x20 with RAM @ 1080 7-7-7-19.
185x20 = BSOD after 5mins of prime.
(1.35v, 1.36vQpi, RAM 6x, QPI 36X, Uncore Auto/18X)
I have tried 200x17, 200x18 and 200x19 ... no go. Higher vCore, vQPI, PLL´s, ICH, IHO etc. doesn´t help a bit.
My temps are strangely low, even tho im running the stock Intel cooler. 3600Mhz 1.3v and prime load is only 65c.
Very low leakage CPU = very bad overclocker?
Anything I should know about the EX58-UD3R? Some kinks perhaps?
Ci7 920 (3841A712, SLBCH)
Gigabyte EX58-UD3R
OCZ Platinum 1600Mhz 7-7-7-16 - 1.65v
what voltage you giving your RAM? Set uncore to 16x, see if it helps.Quote:

I was a bit surprised when it actually loaded windows and could complete a few benches.
If the 38x divider is somehow faulty my hopes for 4+Ghz are gone. QPI of 4400+Mhz is probably not going to happen.
Im about to run some prime now.
Hi there i got mine @ 3800 but im trying to go for 20x200 and so far is a no go, i tried ging it 1.38v for the cpu but wont even load windows, just stays black screen, what settings should i go for here? you guys can see what i got in my rig, memories, board and the batch :) im using F5G for the bios.
Thanks :)
having QPI at anything over 4Ghz could really cause stability from what i've understood. can you lower it under 4GHZ?Quote:

I can run 180 BCLK with QPI multi @ x36, but only with 6x RAM divider. Anything above 180 BCLK is no go, no matter what voltages or dividers I use.

what about the voltages? to the dram, vcore and qpi/vtt?Quote:

If you want to go for 4GHz, try dropping your memory multiplier to 6x instead of 8x and increase your core voltage to 1.425V to start (enable load line calibration or whatever is the equivalent on your board). Also, like in the 3.8GHz OC set the QPI Voltage to 1.35V and DRAM around 1.65V. 20x multiplier is hard to get stable and not every chip can do it reliably.Quote:

Normally it should go with no problem,because i have still space in voltage when he is under load.
In Bios i have 1.25625Vcore..Idle gives me 1.24V load 1.248V..so there is still room to go higher.Have test many times on lower speeds
with a Vcore and go step by step higher with TurboV...200-201-202..and so on..check the load and idle..if you not reach your Bios Vcore yet
then one step higher,till it fails,then put Vcore higher and test again.
So also the same with memory and qpi/dram voltage...but 208 don't goes anymore..in Bios no boot..with TurboV it jumps automatic back to 207
Any help or idea are appriciated..if i know the missing setting..i can continue testing to find a better spot!
The cpu has no problem to run 20x200...but i want to see how high i can go with the bus freq.with lowest voltages and temps!!

4Ghz 1.225v running right now on water cooling. Most of my parts were cheaper but performed within 10% of the best parts out there. One core slightly over 80C with the others still in the 70's. It did take a lot longer to get that high though. No worrying about a 10 second run hosing me on temperatures it takes 5-10 minutes.
Yes this is all with HT on.
what does your water cooling consist of? with HT on at 1.329v 4 Ghz I dont go over 70ºc an any core :confused:Quote:

BTW room temperatures are 26-28C. Also will probably add 3 more fans to the bottom of the radiator. All being said 20-30C drop going from a decent air cooler isn't bad at all.
well i7's need some really good cooling. Basic wont work the best. I say about $250-300 maybeQuote:

EDIT: full temps might be closer to 70C after I make a few more modifications. Looks like about a 4-5C drop just adding a single 120mm fan to the bottom side of the radiator.

Some of those people over there are crazy and can spend $300 on just bling alone. If your resourceful you can get a very good system for about $200 but 10-20% more performance increases the price to $300+.Quote:

You can change the rad or pump save a few bucks here and there, but this is what it'll run ya. Look for used parts, they can help save lots of money and work just as good. Lots of people sell Thermochills PA 120.3 rads, they are amazing rads and you can save a few bucks like that

oh really ... hmm i will have to do some research =PQuote:

Thought I might repost my question in this thread as well. (Original Post: http://www.xtremesystems.org/forums/...postcount=2489)
Using a GB EX-58UD5, F5 Bios.
I can't get my 920 to 3.8GHz stable.
I can do 180 fine at:
20x Multi
Vcore 1.3000
QPP/VTT 1.3000
Turbo/HT/All Power Saving Functions OFF
Load Line Calibration Enabled
VDIMM 1.64
PLL 1.80
Memory Multi 8x, Uncore 16x
Memory is a G.SKill PI kit rated at 8-8-8-21 @ 1.6-1.65V
Tried upping volts, using different multipliers (CPU down to 19x, Uncore up to 18x), I SEEM to have 3.7GHz stable with just Vcore upped to 1.4000V (45min of Prime95 so far).
Thoughts?

try my setting but i dunno if it will work out the same for you i have a asus p6t deluxe v2 so not too sure if it will work the same.
I'm gonna try to lower my vcore if i can get it stable at my setting and so far so good at 9hrs prime95 blend test.
temps at 76.

I'm happy with the result, but a little worry about the temps at idle..44 degrees :S at around 70 something degree on load..
I'm 8+ hrs stable stressing using Prime 95. Will do a 1hr OCCT Linpack now, just to be doubly sure.
EDIT:
ARGH! I don't believe it... 40+ minutes into Linpack, whilst screen saver was on, Windows sorta froze. It SEEMED like it frozen, then from random keyboard bashing, it looked like it was going to return to desktop (start bar became visible) and then just hung. Not sure if it was a stability issue or just windows =.="...
EDIT2:
Okay... I tried 6x memory, 12x/13x uncore and still not getting anywhere with bclk.
Vcore was 1.4000
QPP/VTT was 1.3400
PLL was 1.88
VDIMM was 1.64
Need more help...
Getting better :) I see room temps matter A LOT. One extra fan dropped me to about 75-77C. At night I have the AC set to 76F and here is what a small drop in room temperature got me (note it was mostly 72-73 on core1).Quote:

I'm thinking of changing BIOS rev again... however, don't know which one would be best (I've used F5 and F6e on my GB EX58-UD5, so need something more stable). Maybe up Vcore above 1.4000 BIOS? Up QPP/VTT voltage as well? VDIMM is set at 1.64 in BIOS but drops to 1.616 on load.
I really dont wanna give up and admit I have a bad OC'er...
your temps are fine, these things can run up to 100ºc. Just try to stay under 90ºc. Glad the settings worked out :)Quote:

Just out of curiosity, what temps are you guys getting?
My i7 920 (4GHz @ 1.344v CPU-Z) is under a TRUE-120 and I'm getting about 39-42*C idle and 73-77*C load.
Just wanted to compare to see if my temps are normal.
I'm running noctua nh-u12p and my idle is 40-43*C and Load 83-85*C so your not bad
I am only at 3.8ghz as well 1.35v vcore
With a TRUE 120 and Kaze 3000
http://img21.imageshack.us/img21/520...assp956hrs.png
I have my Corsair Dominators 6gb set at 6-6-6-18 1T is this gonna be okay?
I want a TRUE 120 now =(
i wish i got that from the start...
I see alot of ppl with true 120 their temp are so much cooler than mine..
Is your set to 3000rmp stock? or u set it at that speed?
as long as it passes linx, p95, and memtest that's great!
default speed is 3000rpm w/133cfm and 46db loud but does the job. I have a zalman fan mate I will be putting back and setting to 1900-2000rpm which moves approx 88-90cfm once I'm done with p95
Did you set your cpu fan to 3000rpm?
I want a true 120 now :P haha
i cant get mine to be stable with lower voltage..
The TRUE is only 1C or 2C at with the same fans, the noctua's mount is 10x superiour to teh one of the TRUE. I'd take the Noctua.Quote:

I'm sure only one of those would do the trick, not sure about the performance you would get but they would be insanely loud
Yeah i know i read about it.. But i just need a higher RPM fan..My nortua only at 1300RPM I have dual but still not doing the trick
I might get the KAS 3000 as well 2 of them for my Nortua and see if it help

Whats the magical cure (not including buying another 920 =P)?
It's been a while since I 1st owned the Noctua HS but assuming those fan clips can hold a 38mm fan I don't see why not. If not there is always the option of using cable ties or rubber bands. Can someone chime in on this....
BCLK seems to still be my weakness as well. I hit a wall about 216 and have only been able to push to 218 or so for tests but not stable. This limits me because the x20 multiplier needs more voltage and x21 really doesn't work well at all. My 24/7 is 19x211 @ 1.215v.
I'm not sure what the size of the fans that came with the norctua i know its 120mm but not sure what u mean about 38mm?Quote:
