Will have to check my 120 extreme to see how it is sitting - my idle temps at stock with turbo mode enabled are 36.31,32,30 room temp about 19c
prime temps at load 62,58,58,57 at 21 multi 2.8gig

My True Black seems ok ,but it does move if i twist it quite hard.I might try the washer trick at some point.I always liked Gigabyte Boards but this e58-ud5 is going to take time to tame,i loved my last board a p35-ds4.

I lapped it, thought it was making good contact, BUT, after taking it out to reseat because of stability issues, i saw that contact was poor.Quote:

I am still having problems,I have tried bios f4k but i still have the same problems:-
I can post normally up to bclk 172 ,anything over and i cannot post normally.System restarts a few time before displaying the overclock error.
BCLK 171 and 172 are untstable:mad: anyway with hard locks in vista and even in the bios.Turbo on/off or ht on/off makes no difference also using more voltage on the below settings makes not difference.If i cannot boot above 172 i cannot test!
f4 offical bios. tried f4k,f4l and f5a
I am now running 21 x 170 3570Mhz
vcore 1.2875
qpi/vtt 1.18
qpi pll 1.84
cpu pll 1.14
ioh core 1.12
ich i/o 1.58
ich core 1.14
dram 1.66 manually set 8,8,8,24 2T
qpi,unicore and mem on auto (make no difference if i set x36,x16,x8)
also cpu clock drive set to 800mv pcie set to 900mv
all other settings on auto
All power saving options off.
I have run linx on the above settings for 2 hours.
Does anyone else have trouble over bclk 170?I must have a bad cpu or motherboard.I think i might try another board once the chipset matures , there will be some better board released i am sure.
tony - maybe try to isolate the problem?
Turn the mutli's for cpu, qpi, uncore and ram as low as you can - then start raising block - you shoud be able to get to 200 or better!
turn multi's to -
cpu - x16? - if it will go this low?
qpi - x36
ram - x6
ram timings on auto.
To make sure voltages are not your problem - set voltages:
cpu - 1.4
qpi - 1.34
dram - 1.64
make sure all the c's and eist are off.
maybe start with HT off
start at a bclock that has worked before and move up from there.
Once you know your mobo's max bclock you can move on to memory or cpu ocing.
I word on memory ocing - I am finding that memtest x2 successful pass (no errors) in insufficient to find max memory oc (speed and timings).
I wonder if this is because of the new IMC being on the chip.
What are folks using to determine max memory oc?
I've never used memtest for anything other than verifying stability @ stock (ie if your dimms don't pass memtest @ stock then it's RMA time)
In my experience you will always get errors in memtest on overclocked sticks, even if they're 100% stable in prime etc. Maybe this is not the case, but it definitely has been for me the past few years.

I have noticed the auto setting are qpi=36,ram=8 and unicore=20.All cpu power management is always off.172 is the max i can get ,its not stable in vista anyway (freezes) also freezes in the bios.
I have just accepted i have a bad board/cpu.I might mess with the corsair mem sticks later (swap them over try dual and single channel etc).Also i might strip the whole lot down and run outside the case with 1 hard,video,ps2keyboard and mouse and 1 stick of memory.I guess i am unlucky this time:mad:I have spent about 20 hours on this and never had such a hard time overclocking ,i started with a vanilla pentium mmx all those years ago.I used have a mach2 - loved that and loved the massive overclocks.
Thanks for your help i do love this forum!
tony, there are some cpus that have low max bclk's, and you may just be unlucky....I did not read all your messages, but I assume you hit load optimal settings and save after each bios change to get the settings of the new bios. Also, I would try running with 1 stick of ram, if does not work, try different 1 stick of ram. Earlier I had 1 stick ram that was defective that was screwing up my OCing. Also future bioses may help. I am stable at bclk of 200x21 and even 205x21 with prime on F4j and F4m (extreme), but on bios F4, I cant get any higher bclk than 170's, so something screwy in F4 bios on mine.
Tony - what bios have you tried? - I see it, try to stay with one of the f4 beta's not the f4 final.
F4r for ud5 seems to be the one most folks like for that mobo.
I think I read that F4k should be good for UD5 - you already tried rats - :(
Maybe time to start taking memory out.
You only need the uncore at twice the memory, have you tried just x12 UCLK with x6 mem?Quote:

Never mind - I found it, had it on a flash dr.
...This board is for me a X-File.
Today I have been testing a new OC policy, trying to find how far I could go up the bclk without changing a safe voltage in the qpi/vtt: 1.34v. Beginning in 200, I've gone up, I tested, I have gone up, I tested ...And I have come to 211, and I've tried very seriously with Linpack. Stable!!
I have taken almost a week to find the lowest achieving super-stable voltage in qpi @ 211: 1.40v. Today, all is different: 1.34v.
I am very puzzled. What has changed so much in a few hours? Today it's cooler in my city, but passed 3 hours of Linpack the PCB should already be pretty tired. The system should be hung. But the board has passed 6 hours of testing.
Now I'm also trying to lower the Vcore. The system remains stable after half an hour of testing. Yesterday was restarted in 5 minutes.
I see the Auto values shown ET6: always the same.
I dont understand anything ...
Edit: System reboot. Vcore has not much changed his behavior
Is it just me ? or 1.65V is missing from the BIOS for DDR Voltage option.
I tried to slightly overclock I7, but found that using AUTO voltage seems to be a big mistake. When I looked into EasyTune after putting BCLK to 150, DDR Voltage was 1.792V<Auto in Bios> and CPU Voltage went upto 1.35V <Auto in Bios> and QPI/VTT was set to 1.215 in BIOS.
I went to Bios and set CPU Voltage to 1.185, Memory to 1.5V and QPI at 1.215V. Setting QPI lower that 1.215 means BSOD while loading windows.
I just use 1.68, which ends up showing 1.66 in the PC health page
Tony flash to F4f
use NB speed four times the RAM frequency speed
also your uncore is TOO LOW....bump it up to 1.5v just for initial testing
leave the rest of volts on auto except RAM (1.64v and vcore > whatever you required there)
boot direct to 190/200/210
i run past 1.5v uncore all the time for bencing........my RAM volts are 2.1v usually so dont be shy trying volts as long as uncore is not really low and your vdimm high
if you decide to run higher NB speeds this is usually where uncore and vdimm require a LOT more volts..........
i am only suggesting you start high to check if its the volts just in case
then you can drop them as you keep testing to find the sweet spots for your setup
I just finished testing F5a and it works fine. I even used my bios profile from F4r/F4k. Only thing I did notice about F4k that I didn't like is that even when the memory timings are manually set to 8-8-8-21 it wants to run the ram at 10-8-8-21.
edit: the F12 bootMenu works fine for me.
Already tried f4f and if i set my qpi/vtt higher than say 1.20 it will not post correctly (keeps restarting and powers off then starts @defaults with bad overclocking message) also noticed it displays 6F when these restarts happen.Quote:

Following your voltage advice
vcore 1.41 (for testing)
vtt qpi 1.5 (won't post correctly) BUT BOOTS normally if i use vtt/qpi 1.18
If i leave mem,qpi,ram multiplyers on auto they are x8,x36,x20.
I think i might try f5a again and 1 stick of dram.I think the issue here is i have a poor cpu:mad:Not noticed in this thread of any really bad i7 920's but overclocking is normally luck of the draw.I wonder if its worth tring another x58 board:rolleyes:
I might try f5a again,do you mind if i have your bios settings?Quote:
