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.

i vote for sticky! ill have my results asap once my system is alive again

Maybe you should break the ice gwai lo. I would, but I'm still running a Pentium D 805 =(

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 will post mine as soon as I get a new processor!

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

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.

here's mine.

Very interesting. I'll post mine as soon as I overclock my E6750 to 3.0GHz.

Processor Core2Duo E6550 @ 2.8GHz

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. It's only a minor OC, and I haven't tried to push it any farther.

w00tness

thanks Radish!

Keep the submissions coming guys.

No problem

Gave me an excuse to unpin the "Overlclocking your Athlon/Pentium 4" threads

I'll post my submission soon as well.

Radish™

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:

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.

Looks like this thread is ALREADY proving to be useful

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. 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?

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.

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.

http://channel8.msdn.com/Posts/2019/

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".

And I thought chc was the only guy with a Core 2 Extreme on the forums. I guess I was wrong!

I guess you can update my Mobo entry too, nothing other than the FSB has changed (429MHz)

Sometimes I do not believe it myself.

gwai lo: I noticed you're running 480FSB, were you able to run your RAM at a 1:1 ratio?

I haven't overclocked my OCZ Plat Rev 2 yet so I'm not sure how high I can go. 240MHz seems like a pretty large overclock when it comes to RAM.

Or do you have your RAM watercooled as well?

Yeah it was 1:1, but not on water. Just an 80mm fan blowing over the DIMMs and the NB...however I can't find my screenshot and I can't seem to get it stable again (might be the heat right now..dunno). So I'm going to remove the entry, but yeah these sticks did pretty good.

Am I missing something here, I can't edit my original post, I wanted to add...

You only get about 15 minutes to edit your posts, (unless you're the Thread starter).

It looks like we're getting a good variety of CPU's for the list so far.

Yeah, looks pretty good.

And holy crap, Santiago you're running a pretty low V Core for a 3.2GHz Q9450.

Quick update: on my Vcore I've reduced it to 1.176v to drop the temps, and ran Orthos for another 9+ hours and was stable, but I forgot to take a screenshot of it . I was just happy to see my max temps at 56-57c. I can't believe how little voltage this cpu needs, the default 1.32v seems like quite a lot. Here's the CPU-z shot:

Thats good, isn't it?

At idle is 1.152V, at load 1.120V, the same as stock.

It is good. That's probably why your temperatures are so low, 49C load. Very little Vdroop as well but that's probably more motherboard related if anything.

Yep... the only annoying thing is the Core0 temp difference

Not until I get a QX9770 or something.

But anyways, this is the lazy way of doing it. Increasing the multiplier.



I dropped it from 4GHz since it wasn't worth the extra volts. Mine is ES as you can see, but this one is complete junk when it comes to overclocking -- can't do 4GHz until 1.43V.

I've pulled way better OCs before, but this is good enough heh. I think I am going to get the new OCZ Flex II soon, the Striker II NSE reverses the RAM orientation and it looks ugly in my case

only thing i'm kinda worried about is temps
i just put a new heatsink in. i've read that it takes time for the thermal paste to set (or cure?) and i can see a drop in temps of ~5 degrees?

About 200 hours I believe. Depending on what thermal compound you use.

You're fine, most people define 15°C-20°C under Tjmax as being safe. Desktop Wolfdale Tjmaxes are 95°C.

yayuh first 500 FSB posting. That's good enough right now for the FSB submission.

I'll have both of you guys added in a few minutes.

I find it encouraging that Vista x64 is being used quite a bit....

Windows 7 is quite a bit faster, these machines are going to run beautifully! Not that they don't already

I don't think there's a difference in overclocking across different OS' though.
The only difference is that some 64bit users might be running 4GB of RAM.
But otherwise I think it's more dependent on the chipset and cooling.

Intel Core 2 Duo E4500
D Stepping
1.38 V-Core (Set to Auto in Bios because it isn't stable for some reason if it isn't)
Stock Intel Box Cooler (Air)
Gigabyte P35-DS3L Rev. 2.0 With F7 Bios
Windows Vista Business x64
Kingston KVR667D2K2/2GR (2GB of RAM) and Kingston KVR667D2N5K2/2G (Other 2GB of RAM)
Both 2GB Kits of RAM are 667MHz (PC2 5300)
The stock latencies are 5-5-5-15, but I have them running at 5-4-4-15 at 792MHz

Stable with prime95 for 12 hours. The temps hover around 60 degrees celsius when running prime 95 after a couple of hours, so I think I'm ok temperature-wise.

Remember to include CPU-Z screenshot of CPU, Mainboard and Memory tabs.

As well you forgot to include what speed your CPU is overclocked to.

Check CrashGordon's post on the first page for an example of how it should be formatted.

I was just about to do the same thing.

@Citrusleak: Also, a screenshot of Orthos or Prime95 for 8+ hours would be nice too.


@Gwai: can you update my Vcore to 1.176v?

Actually, don't do it quite yet. I had run Orthos for 9+ hours the other day and it was fine (but forgot a screenshot), so today I was going to rerun it, and it doesn't seem to be stable. I get an "This Program has encountered a problem and must close" or something in Orthos, although everything else is fine. It's almost like DEP kicked in and shut it down, although unlikely, but it's the same type of error box. I'm doing some more investigating to try and pinpoint if it's the voltage or just Orthos. I'm trying 1.192v now. I will remember to make a screenshot this time if all goes well.

I'm pretty sure it's voltage. I had that happen to my Pentium D when I undervolted it a bit too much.

I'm pretty sure that's what it is. Also, it would fluctuate between 1.180 and 1.176 at idle, under load it would stay at 1.176. All other voltages i've tried it stays steady. It looks like 1.192 is going to be what works. It'll keep the temps at 38/58 (min/max) so that's 35c+ below tjunction max of 95c. I've got a build to do for the wife in a few weeks, so I might be able to sneak a ARCTIC COOLING Freezer 7 Pro in there along with my new Acer V223Wbd Black 22" monitor.
