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

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

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.

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. (Y)

Yeah, looks pretty good.

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

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 :pinch:. 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 :wacko:

Not until I get a QX9770 or something.

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

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.

Processor - Intel Core 2 Extreme QX9650

Stepping - C0

Vcore - 1.35V

Method of cooling and make and model of cooler - Air - Noctua NH-U12P with Noctua NF-P12 @ 1100rpm cap

Make and model of motherboard with BIOS version - Asus Striker II NSE, 0305

OS version - Windows Vista Ultimate

RAM brand, model number, frequency (actual not effective), and latencies - Super Talent Project X DDR3-1600, 800MHz (1600MHz), 7-6-6-18 Unlinked mode

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 :x

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.

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. :p

@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. :shifty:
