The 920 chip has locked mulitpliers, 12-21, 22 on certain boards, with some bios' lol

Patch

Great clock, great voltages, awesome pi and great idle temps.

It's clear that the D0's truly are an upgrade.

My only criticism is that your clock is with turbo on and the screenshot is after stopping Prime. Prime downclocks turbo, so unless you played with BIOS settings to ensure turbo stays on 100% your actual stability testing was somewhere between 4.3 and 4.4 Ghz.

nope, 21 locked. lol different bios, and lock 22..

• CPU Bus/Bclk speed 471 FSB
• CPU multiplier setting 8.5x
• CPU core model Yorkfield
• CPU batch/stepping E0
• CPU voltage 1.232, idle and full load
• Motherboard model EP45-UD3R
• Cooling Today I am testing with my Arctic Cooler 7, although my Xigmatek is in the mail and coming tomorrow
• RAM size/model 4 GB G. Skill Overclocked to 940 MHZ
• RAM speed 940 MHZ
• SuperPI result (1M) - Testing now


Edit : SuperPi hangs upon opening and says its not responding when I click it..? I'm using Windows Vista if that matters


Edit : Found a vista fix! Type net stop "audiosrv" in the cmd box and when you want to turn your audio back on type net start "audiosrv"

Well here's an update to my earlier overclock (got to 4GHz before). My Biostar board started to flake out on me (kept getting 9A error code). Biostar wanted me to RMA it but I just went back to Microcenter to exchange it. While I was there I also picked up some OCZ 4GB for $39! My previous RAM was GSkill PC6400. Well I got it to almost 4.3GHz with only 4 changes in the BIOS (CPU volts +.150, FSB(bsel)=1333, multi=8, FSB=533)!! I am sure I can probably get higher because I haven't even started to stress the RAM with these settings. I love this board and chip!!

• Processor model: Intel E8400
• CPU clock speed: 4.26GHz
• CPU multiplier setting:8x
• CPU core model: Wolfdale
• CPU batch/stepping: A138, EO
• CPU voltage: 1.328
• Motherboard model:Biostar TPower I45
• Cooling: Tuniq Tower 120 - lapped

Here's the results from my story about throwing together a bunch of ancient hardware and trying to kill the evil b0x0ns marked eMachine! I'm still laughing at these results off that horrid system:

• Processor model: Pentium 4 Northwood (D1)
• CPU clock speed: 3,381.50mhz (2.6ghz default)
• CPU Bus/Bclk speed: 520mhz (400 default)
• CPU multiplier setting: 26x
• CPU core model: Northwood
• CPU batch/stepping: 9, D1
• CPU voltage: 1.765v
• Motherboard model: FIC VG-33 (roflcopters!!!)
• Cooling: Default factory heatsink & air cooling (google says factory used a $12.99 starteck model)
• RAM size/model: 512mb Samsung & 256mb Hyundai Electronics (laugh with me here)
• RAM speed: PC2700 Samsung & PC2100 Hyundai Electronics (horrid I know)
• SuperPI result (1M): 04A0F9D0
• CPU-Z Validation: http://valid.canardpc.com/show_oc.php?id=552679

Attached screenshot includes the 7+ hour In-place large FFT's run with temp data & the rest of information! Now I think I can finally play SimAnt without a slideslow! ... ...
