Intel Processors Overclock Database


Recommended Posts

Here's a larger, more comprehensive online database: http://www.cpuoverclockers.com/

Seemed like we could use one of these, stealing the basic format from other overclocking databases because they work. ;) Gives users an idea of what to expect or about where everyone else's chips are.

Please list:

Processor

Stepping

Week and code (found on retail box and processor, formatted as LXXXAXXX with LXXX being week and AXXX being code) (optional)

Vcore (idle CPU-Z)

Method of cooling and make and model of cooler

Make and model of motherboard with BIOS version

OS version

RAM brand, model number, frequency (actual not effective), and latencies

All submissions must include a CPU-Z or CPUID picture or a CPU-Z validation link.

All submissions must be 8+ hours Prime95 or Orthos stable, included picture would be nice if not we'll trust you. :)

I also want to add a section for motherboards here to help shed light on what motherboards are doing what kind of front side buses. The best method of doing this is pretty much just dropping the processor multiplier and pushing the front side bus as far as the system will stay stable.

Please indicate whether or not your submission accurately portrays the maximum FSB reached by your motherboard, if not we're going to assume your submission is for the processor section only

Please post:

Processor

FSB (actual not quad pumped)

Motherboard make and model (revision number if applicable)

BIOS version

Northbridge and/or Southbridge Cooling Method

Any mods

Same thing, with CPU-Z/CPUID, but we'll accept four hours of Prime or Orthos stable.

Any submissions without any of the listed information will not be included in database

Try to keep the thread clean of the "nice oc" and "what settings did you use" posts, use another method of communication.

Also, if you made an initial post but improved on that overclock later, go ahead and repost but link to your original post. You can make multiple submissions for processors and motherboards, such as overclocks for both an E6600 and E9450. However, if you change out the motherboard, but keep the chip I'm just going to change your submission for the chip. E.g. I post my E6400 + Abit IP35-E overclock, then change the board out to an IP35-Pro. The entry will be edited to just replace the motherboard.

I'll try to make updates as often as possible, but don't expect to have your submission show up three minutes after you post. ;)

..alright, let's see how this goes. :) Go ahead and PM me if anything needs to be cleared up or if I made a mistake somewhere that should be rectified.

Yeah I'm going to get around to it, I had the idea randomly in the middle of the afternoon as I was heading out. Haven't been on the computer for 15 hours else I would've added my own. I'm orthosing right now and I'll put up my 3200 MHz Orthos image by tomorrow morning. Don't have my week or code written down for some reason and I don't feel like taking the block off to check it. -_- but yes, if anyone else gets their data in before tomorrow morning 11AM PST you can be in the first update. :)

edit: Okay....yeah I'll break the ice. update coming up!

I'm posting mine ASAP....in a month that is. :p

As soon as I build my gaming rig for college I am immediatly overclocking it. As it is looking right now the setup is: Q9450, Asus P5K-E, 2x2gb, 9800GTX, 2 320gb WDC AAKS drives, etc. I can't wait to see the results.

Processor Core2Duo E6550 @ 2.8GHz

Stepping B

Revision G0

Vcore 1.232v

Method of cooling and make and model of cooler Air, Stock

Make and model of motherboard with BIOS version Asus P5K-e 1013

OS version Vista Ultimate 32bit w/SP1

RAM brand, model number, frequency (actual not effective), and latencies G.Skill, F2-6400CL4-1GBHK, 400MHz, 4-4-3-5 2T @ 2.1v

It is perfectly stable running Orthos for 8 hours, I've had it at these speeds for around 2 months and just didn't save a screenshot of it at the time because I didn't ever think I'd need one. :p It's only a minor OC, and I haven't tried to push it any farther.

Just in case anyone is having trouble finding time to do an 8 hour ORTHOS/Prime95 stress test, here's what I do.

I just leave my computer on overnight (for one night) with ORTHOS or Prime95 on, and have it stress CPU over night.

If in the morning, the test is still going, then it's safe to assume your overclock is stable. If you get a BSOD overnight, then there might be a problem with stability.

Hope this helps.

I guess I should've added this for the Mobo list:

Processor Core2Duo E6550

FSB (actual not quad pumped) 400MHz

Motherboard make and model (revision number if applicable) Asus P5K-E

BIOS version 1013

Northbridge and/or Southbridge Cooling Method Stock

Any mods None

Use this with the other screenshots in my last post (nothing has changed)

Thanks for posting that one so much! I am planning on putting a Q9450 in my rig next month! I hoping for similar results to you, at least 3.2ghz.

I'm testing my E6550 @ 3.0GHz right now (429x7), ram is at the same FSB (x2 for DDR) with no change in timings or voltage on anything. It's looking very good so far, temps are no more than they were at 2.8 (Max. 58-59c) on the stock cooler. :yes: I'll post the results when Orthos finishes it's 8 hours or when I wake up tomorrow morning.

How can you spend that much money on a processor and not overclock the crap out of it? :p

I won it, my motherboard doesn't like high front side buses, I like an "auto" multiplier so on idle it clocks down, and I don't *need* more....yet ;)

Someday I might really try to go for more, but 3.4 sounded good.

What?!? Seems like I'm entering the wrong sweepstakes because everybody is winning hardware but me. :p

Where from?

Don't worry too much about getting a high overclock, it's not a show off thread, just information. In this case the vcore used is still information for those looking for some numbers to compare to. ;) So this is for everyone else holding off because they don't think they're clocked high enough...we just want numbers. Any of them are good.

I'll have you added by tomorrow afternoon, I have work at 6AM till 2 or 3 PM.

edit: hah I know what you're talking about. Mine aren't titration though, but stress/strain. :p

I tell you what, my engineering apps are f***ing fast now. Excel is much improved too, so I can do graphs with thousands of data points....I'm such a nerd.

Yeah I've done a few of those, they getting pretty bad. I think the computer took readings every 5 miliseconds when we rode bikes around campus measuring the stress/strain on the frame. I thought excel or my computer was going to die.

This thread will probably prove to be extremely useful. I guess even if the clocks aren't high, people can at least see what was "stable".

    • Microsoft releases major feature updates for stock Windows 11 apps by Taras Buria In addition to releasing new Windows 11 preview builds, Microsoft announced that inbox Windows apps now have dedicated release notes in the official documentation. At long last, users have access to all the release notes for each app, with changes listed in chronological order. Microsoft used to announce feature updates for stock apps with each build. Now, with Windows Insider release notes hosted on the Microsoft Learn website, each app has a dedicated space for its changelog, which is very useful for those who want to track new features and improvements. Alongside that, Microsoft dropped massive feature updates for six stock apps: Clock, Media Player, Calculator, Voice Recorder, Photos, and Paint. Each app packs quite a lot of changes and new capabilities, so here are the release notes. Here are quick notes so that you can jump to the app you are interested in the most: Calculator Camera Clock Media Player Paint Photos Sound Recorder Here is what is new for the Calculator in version 11.2605.9.0: More accurate square-root results — Fixed rare cases where a calculation that should equal zero (like sqrt(2.25) - 1.5) returned a tiny leftover value instead. Readable text in High Contrast themes — Settings text now shows the correct colors in the High Contrast Aquatic and Desert themes. Fixed layout for right-to-left languages — For languages like Arabic and Hebrew, the graph, number pad, equation fields, and scroll buttons now appear correctly oriented. Reliable launch after upgrading — Fixed an issue where upgrading from much older versions could leave outdated settings that stopped the app from opening. Here is what is new for the Camera app (version 2026.2605.7.0): Zoom slider works on more cameras — The zoom slider now works on the latest cameras, respects your system zoom settings, and updates instantly when you change those settings. Full range of zoom levels — Fixed an issue where the zoom slider only showed three steps on some devices that zoom in finer increments. Front camera works on more devices — Resolved a problem that blocked the front-facing camera on certain wide-angle devices. More video resolution choices — You can now pick video resolutions that were previously hidden; the app shows a heads-up warning instead of removing them. QR links you can still use — When a scanned QR code points to something with no matching app, the link is now copied to your clipboard (with a notification) while still offering a Store search. Smarter default settings — When you haven't set a preference, the app now follows your system settings by default. The Clock app has a massive changelog with the following improvements in version 11.2605.9.0: Timers keep counting after they hit zero — When a timer runs out, it now keeps counting up (for example, -00:27:31) so you can see how far past the time you've gone. You can turn off the daily goal — Focus Sessions now include an "Off" option so you can skip setting a daily goal entirely. New 15-minute snooze option — Alarms now offer a 15-minute snooze interval. Run up to 3 countdowns at once — The Countdown Widget now supports three simultaneous countdowns, up from two. Timer Widget notifications now appear — Fixed an issue where the "timer finished" notification didn't show when the timer was started from the widget. Less clutter in Focus Sessions — Tasks you've already completed no longer show up in the Focus Session task list. More accurate focus progress — Fixed a rounding issue that could show your daily focus progress as a minute short (for example, 49 minutes instead of 50). Smoother World Clock comparisons — The World Clock compare page now loads dates as you scroll, so it feels more responsive. Up-to-date World Clock locations — Refreshed country and city names to match their current names. Correct sun and moon icons during midnight sun — Fixed an icon that wrongly showed a moon during all-day daylight in polar regions. Fixed back-button behavior in clock comparisons — Pressing back once now takes you back as expected, instead of jumping the date to 1926. Corrected the Newfoundland time zone — Newfoundland now uses the right time zone (St. John's). Disabled alarms stay looking disabled — Editing a turned-off alarm no longer makes it appear turned on. Cleaner timer cards — The expand button is now turned off on timer cards that have no time set, preventing actions that wouldn't do anything. Clearer theme setting — Updated the wording to "Choose your preferred app theme." Smoother Settings links — The "About" links in Settings no longer trigger an unexpected "switch apps" prompt. Fixed spacing in Spotify settings — Corrected uneven spacing in the Spotify settings card. Better focus visibility in High Contrast — The focus highlight in World Clock is now clearly visible in the High Contrast Aquatic and Desert themes. No more double announcements — Screen readers no longer read the timer value twice. Countdown names read correctly — Screen readers now properly announce the name of each countdown. Keyboard focus stays put — Focus no longer disappears after you press the Timer Reset button. Clearer alarm toggle for screen readers — Tidied up how the alarm on/off switch is announced. The Media Player app received plenty of changes as well (version 11.2605.14.0): Custom captions — You can now personalize how closed captions appear, with caption styling tied to your Windows caption settings, plus a quick link to open those settings directly. "Indexing" banner in the play queue — When your media library is still being scanned, a banner now explains why some items may not appear yet. Fixed the look of selected items — Corrected a layout glitch with selected items in lists. Fewer playback failures — Improved how the app recognizes supported file types, so more files play without issues. Playlists need a name — You can no longer accidentally save a playlist with a blank name. Cleaner look for empty playlists — Improved how a playlist appears when it has no items yet. More stable play queue edits — Fixed a crash that could happen when changing the play queue while the app was switching between sessions. Clearer "missing codec" message — Improved the dialog that appears when a file needs a codec you don't have, with clearer guidance on what to do. A big update is also available for Paint in version 11.2605.61.0: Adjustable eraser transparency — You can now control how transparent the eraser is. Cleaner stamp brush strokes — Fixed visible color shifts and artifacts when using stamp-style brushes. JPEG photos save in place — Opening a rotated JPEG and pressing Save now overwrites the original instead of unexpectedly prompting "Save As." No more crash on bad image files — Opening a damaged or invalid image, from within the app, by double click, or commandline, now shows a clear error message instead of closing the app. Classic selection behavior restored — The selection outline now hides while you move, resize, or rotate a selection, just like in classic Paint. Tidier AI image panel — Fixed missing spacing at the bottom of the AI image generation panel for a cleaner layout. Visible button hover in light theme — Toolbar split buttons now show a clear hover highlight in the light theme. Snappier toolbar — Streamlined how the ribbon lays out, giving a small speed boost at startup. Fewer background crashes — Fixed a crash that could happen while background tasks were finishing up. Stable app shutdown — Prevented rare crashes when closing the app. Fixed layer removal glitch — Deleting the active layer no longer leaves the layers list in an inconsistent state. Here is what is new in the Photos app (version 2026.11060.2004.0): AI watermarking — AI-generated or edited images can now carry a visible Copilot watermark. You choose Never, Always, or Ask Every Time in Settings, with a confirmation when saving. The watermarking is off by default in settings. Better viewing of small images and pixel art — Tiny images (like 16×16 pixel art) now zoom in far more to fill the screen and stay crisp instead of looking blurry. Select scanned text with the keyboard — When text is detected in an image, you can now navigate and select it using the arrow keys, Shift+Arrow, Home/End, and Ctrl+A, with a clear focus highlight. Fixed a crash in text recognition — Resolved a crash that could close Photos while detecting text in images; the app now recovers gracefully. Easier keyboard navigation — Tabbing through the navigation bar no longer stops on hidden controls, so it takes a single Tab to move past it instead of three. And finally, here is the Sound Recorder (version 11.2605.1.0): Waveform shows with Bluetooth mics — The live waveform now displays correctly when you record using a Bluetooth audio device. No more stray scrollbar — A non-working horizontal scrollbar no longer appears at the bottom of the waveform unless you've zoomed in. Mark button ready right away — The Mark button no longer looks grayed out until you hover over it after opening the app. Markers hidden for WAV files — Markers are now turned off for WAV recordings, since that format can't store them — so they're no longer lost silently. Smoother deleting — Quickly pressing Delete and Enter to remove several recordings in a row no longer triggers a "file doesn't exist" error. Fixed a memory issue — Resolved a memory leak that occurred each time a recording started. You can find all these changelogs in the official documentation here.
    • again, an article about Microsoft Edge and ridicules hater's comments
    • From this very same article: "For organizations that prefer a “more deliberate pace”, the Extended Stable channel remains an option."
    • Or every other browser, because they all behave the same, at least the mainstream ones. Firefox does exactly the same: background updates, restart to install them. Haters gotta hate, I guess.
