cstkl1, I sent you a PM...let me know if you got it. I also included some details on what I did to the FZE to make the LGA775 bracket fit LGA1366. I will post some screenshots of my setup later too.

[ACS]

Flashed 1001 , I still cant POST at anything above 196 bckl with any multiplier , voltage, uckl and ram dividers . Running out of options here other than wait for bioses and settle for 4100 HT on which is prime stable for me at 1.39vcc ; 1.35qpi/pll.

Volts are way too low.

Qpi Pll can go up to 1.65V

and CPU can go to 1.55V

[ACS]

Thats my 4.1 stable clocks , ive tried cpu up to 1.65 and qpi to even 1.69 just to check if it will post , dram up to 1.8 aswell. No post at all, lowest qpi and uckl dividers + laxed mem timings

done
as again.. really want them to blindly sent us a 0903 beta modified bios with the tdp/tdc disable by default if things are again not clear.

before the cny holidays in taiwan..

btw did a big complain to coolit
but really would welcome a pic..
thanks ..

[jasonelmore]

haha coolit is on your radar man. spam em until you get things fixed

[cky2k6]

I don't understand how they don't see a connection between a 100a/130w limit and not being able to oc? Do they not realize that these cpus eat power like there's no tomorrow? My chip runs into issues even before 1.3v, because of the heat and the subsequent high tdp. I don't care if they only give us a beta bios which won't be covered by warranty, I just want to oc my chip in peace. If not, then I will get the new evga board, high build quality without the bios policing...

Hi guys!

Thanks for all the good info fellas. I'm stuck at 190 blck 20 multi with turbo on, HT off (LinX stable). Any ideas on how to to reach 200 blck with turbo on?

Here's what I'm running...

920 (batch 3836A984)
RE2 bios 805 (tried 904 but didn't see inprovement)
Corsair HX1000
Corsair Dominator 3x2gb C8
Custom water cooling setup 2 loops








I've tried everything I could think of....vcore up to 1.52, vtt to 1.45, vdimm to 1.70, ioh = 1.40, ich = 1.20 but nothing.

I can post at 200 bclk but it BSOD on Vista splash screen. Highest I could do is 197 x 21 into vista but 5 secs into LinX it crashes.

Any tips or info will be greatly appreciated.

Thanks in advance

Lou.

Hey,

Ok, I can tell what you are messing up right away so I'll have you try something...

Set your settings like this and then try...

BCLK 200MHz
Multiplier Auto
DRAM 1600MHz, 8-8-8-24-2T (to start, tighten later)
CPU Voltage 1.42500V (to start, increase if needed)
QPI/DRAM Voltage 1.35000V
DRAM Voltage 1.65681V

Remove the 700mV differential amplitude and set all other settings on default including LLC.

Try to boot into Vista and see what happens...

[Supafish111]

Thanks for the quick response dejanh!

Followed your settings exactly but was unable to get vista bars to show then it reboots. Tried vcore up to 1.46 in bios....show I go higher?

Also, QPI voltage shows 1.323 even when its set to 1.35. Does yours do the same? On timmings page, am I right to assume 2T is the first item on 2nd info (2N)?

Thanks again!!!

Lou.

[Supafish111]

Hey guys,

Anyone running dominators C8 care to share their timings? Thinking memory might be the culprit holding my 920 back.

Thanks!

Lou.

[dejanh]

No, the QPI/DRAM should be reading pretty much exactly 1.35V when it is set at 1.35000V. Mine reads (measured with a DMM) 1.349V.

I am running the Dominators and I have them set at 1603MHz, 7-8-7-20-1T, 1.35000V QPI/DRAM, 1.65681V DRAM.

Currently running my low voltage OC on my i7 940 at 3.8GHz (19x200MHz) and 1.20625V on the CPU in BIOS.

Have been stable at 4.2GHz with 21x200MHz using as low as 1.39375V in BIOS. Normally I would run 4.2GHz using 1.42500V in BIOS.

Could be the chip, or could be the board...not sure...

Can you take a DMM and measure your set voltages on the board to make sure that they are approximately what they are set at and not undervolting significantly? Maybe it is your board that is causing problems...

[mpower1001]

Supafish111, have you tried Bios 1001, worth a shot?

I will tell you that i had a tough time getting my memory stable at 16000mhz with a 4.2ghz overclock, then i flashed 904 and boom!!! stable as a rock

[Supafish111]

Here are the readings via DMM

BIOS Setting DMM BIOS Reading
vcore 1.4812 1.484 1.468~475
PLL Auto 1.845 1.812
QPI 1.350 1.344 1.330
IOH Auto 1.15 1.14
ICH Auto 1.12 1.11
vdimm 1.656 1.66 1.64~1.54

This is with LLC set to Auto. Gonna load up bios 1001 to see if it helps.

Thanks guys

Lou.

[Supafish111]

Anyone have alternate link to either bios 904 or 1001? Kensek's link doesn't work.

Lou.

[Supafish111]

sigh....bios 1001 didn't do much.

Shot 1.53V to the chip (briefly) and I did manage to see vista bars complete, but after that it blue screens on me and reboots. Even tried running mem on 6x but still no go. These suckers sure are hard to OC to 4ghz.

I envy all the fellas here doing 4ghz+ under 1.45vc. Gotta keep trying tho so keep the ideas coming!

Thx,Lou.

It's just than there has been 100 downloads today and that's all the free account allows.

Try again tomorrow morning.

[Amuro]

Has anyone experienced any sleep wake up issue with this board? I can only wake the computer from sleep with the keyboard, which is a Saitek Eclipse II, but once the computer is up and running, the keyboard would then stop responding. Device manager shows the error "Windows cannot load the device driver for this hardware because a previous instance of the device driver is still in memory. (Code 38)". I have to restart Windows to make the keyboard working again. I'm on BIOS 0903 right now.

thank you

Guys, can I overclock my i920 if I just have PC3-1333 memory? It seems like you guys all have PC3-1600 for those extreme overclocking...unfortunately I couldn't afford it so I settled for only PC3-1333. And if I can, please advise the BIOS settings. Thanks...

Anyone?

[dejanh]

Anyone?

Yes, you can. Just use a lower memory divider if you need to. However, I am pretty sure that your 1333MHz memory will do 1600MHz fine, though you may need to relax the timings to 9-9-9-24-2T or something and use 1.35000V QPI/DRAM with 1.65681V DRAM.

Now, on a different note, I did some stuff on the TDP override front...

I sent a full set of detailed instructions on how to reproduce the TDP problem to the Asus people. It was nicely formatted, in numbered steps and bolded important parts. I also provided them with links to direct downloads for the tools used to stress the CPU and to RealTemp for monitoring the temperatures, clocks, and multipliers.

They replied that they forwarded the information to their engineers and will get them to test it today or tomorrow, and then get back to me.

Let's see what happens.

By the way, below are the instructions I specified...

1. Use an i7 920 retail processor.
2. In the BIOS overclock the CPU using the following settings:

CPU Multiplier Auto
BCLK Frequency 200MHz
CPU Voltage 1.48125V
DRAM Bus Voltage 1.65681V
QPI/DRAM Core Voltage 1.35000V

Do NOT change anything else in the BIOS. Leave Load Line Calibration on Auto, and leave everything else as is.

3. After settings those settings save the BIOS settings, then start Windows.
4. Download Mersenne Prime (Prime95) from this link http://www.mersenne.org/ftp_root/gimps/p95v258.zip
5. Download RealTemp 2.90 from http://www.fileden.com/files/2008/3/...alTempBeta.zip (this is sourced from the first post in this thread http://www.xtremesystems.org/forums/...d.php?t=179044) and is the ONLY program that correctly reads the Core i7 CPU temperature and speed.
6. Unzip both programs to directories.
7. Start RealTemp and look at the top. You will see the processor information there, the current clock speed, and load.
8. Start Prime95 and select "Just Stress Testing" if asked. Next select Options > Torture Test > Small FFTs and then make sure that the box that says "Number of torture test threads to run" says 8. If it does NOT have 8 please write in 8. Click OK and let the test run.
9. RealTemp should now be showing 4200MHz speed, 200 x 21. If it is NOT showing 4200MHz and 200x21 when the CPU is under load you are throttling due to going over the TDP limit. It may take a few minutes for it to show up. Also, the temperatures have to go over 80C.

If they cannot follow this then I do not know what they can follow

If you lowered the RAM down to take it out of the equation and ran that high of a vCore to it and it still wouldn;t boot, it's the chip. It's gotta be.

If you haven't, lower RAM down, and relax timings, then see what the CPU will do. That isolates the RAM out so it won't affect the CPU OC. After that, if it will OC, start raising the RAM into it, then tighten the timings to find the sweet spot. You may have to back off BClk a little too since when you bring the RAM back in it might not run at the max clocks it did with the RAM totally out of the Equation, since the BClk affects both the CPU and RAM clocks.

Check PSU voltages also with a Multimeter and make sure they are stable and don;t droop under load or fluctuate. That can raise havok with OC's. If you can also check voltages at the board. I didn't see what board you have, but on the Rampage II Extreme you can do this. Others, you have to know where to put the probes.

It is luck of the draw with some of these. Not every chip will OC the same...even in the same batch numbers. It depends on where the chip came from on the wafer, how it was binned, the date it was manufactured, and lots of other stuff.

I would check those things above though.
