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

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.

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:

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

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.

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?

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 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.

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?

@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:

EDIT: Sorry I forgot some information before. It won't let me edit my last post.

    • Just pull a 4Chan and ignore the UK gov, or better troll them. It's not like they can enforce the fine across border.
    • It has NEVER been shown that all these overreaching creepy methods of surveillance have ever saved a child or prevented a terrorist attack. Not a single one. It's the kind of people like you who just wave it away as "paranoid conspiracy" that makes big tech and governments this creepy mass data hoarding entities. Not only that, 3/4 of these surveillance ideas undermine the very foundations of safe online communication because they always want to have a backdoor in everything "just in case" they might need it to... checks the notes "save the children". If you put a backdoor into encryption chain there is no encryption chain anymore. You know what encryption keeps safe? Your medical records, your online shopping and credit card during payment, your photos in the cloud, your emails, your passwords, everything. There is ZERO guarantee only the good guys will use it. And if you think police suddenly can't apprehend child abusers because of encryption, Epstein was running his entire sex trafficking ring using GMail which is not even encrypted end to end. Or to make matters even worse, USA has a **** and a good buddy of Epstein as a president. Absolutely NOTHING has been done to address it. Maxwell just got a better "hotel" room as a reward. This clearly shows how they absolutely don't really care about the children but they care about the absolute control over all of us. And you're defending them here. Good grief. On top of constant attempts to insert backdoors into encryption chain, the entire age verification nonsense is again entirely over reaching, creepy, invades everyone's privacy with premise of yet again "protecting the children" instead of demanding device makers to provide simple and powerful tools for PARENTS to control how their children use devices and what they do on them. THIS would be the way, not the stupid age verification for everyone. Imagine if government would be dictating companies how their phones work and not the company's IT department. The parents should be the IT department to their children. And for everyone excusing "they are not knowledgeable enough" buuuuuulsheat. We live in a digital age, if you have children now, you absolutely are well versed in digital everything at least to basic extent. If you're not, how do you even function in these times then? Reality is that parents are just lazy and don't want to deal with this. They want government to raise their kids because they are too busy scrolling stupid Instagram and Tiktok or some bs.
    • You could make the argument that K should not be included, but FC, the fried chicken, is not the framework, it's the product. It's the Paint in Paint.NET. A closer analogy is if KFC included the name of the deep fryer they used. HennyPennyFC.

    • Apple is expanding Private Cloud Compute beyond its own data centers by Pradeep Viswanathan At WWDC 2026, as part of the improved Apple Intelligence capabilities, Apple today announced that it is expanding Private Cloud Compute (PCC), its privacy-focused cloud infrastructure for Apple Intelligence, beyond its own data centers for the first time. Private Cloud Compute was designed to handle Apple Intelligence requests that are too complex to run fully on-device. The PCC system does not store user data and does not allow Apple or anyone else to access user requests. Last year, Apple also expanded its Security Bounty program with rewards of up to $1 million for researchers who could find serious vulnerabilities in PCC. Until now, Apple's PCC data centers were using Apple's own silicon. As part of the expansion, Apple is working with Google and NVIDIA to run new Apple Intelligence workloads on Google Cloud systems powered by NVIDIA GPUs. Apple will be using this new infrastructure to execute more demanding AI tasks while maintaining the same privacy and security guarantees of PCC. The new implementation uses NVIDIA Confidential Computing with NVIDIA GPUs, Intel CPUs with TDX, and Google’s Titan chip. Apple says it has worked with Google to build additional protections beyond a traditional confidential computing deployment. Despite the expansion to third-party data centers, Apple claims that its core PCC requirements remain unchanged, including stateless computation, no privileged runtime access, non-targetability, and verifiable transparency. The company highlighted that it will continue to control the PCC software stack, and Apple devices will only trust PCC software that has been cryptographically approved by Apple. To take security to the next level, Apple mentioned that it is maintaining an append-only ledger of Google Cloud hardware that is part of the PCC fleet. The company claims this will help reduce the risk of supply chain attacks. In addition to AI infrastructure, Apple also worked with Google to use technologies behind the Gemini family of models to build the next generation of Apple Foundation Models to power Apple Intelligence features across on-device and cloud workloads. As expected, for more demanding AI tasks like agentic tool use and complex reasoning, Apple will rely on the expanded PCC infrastructure running on Google Cloud. The expansion of PCC on Google Cloud will gradually ramp toward the full set of protections during the summer preview period. As before, Apple will also publish binaries for public inspection, provide research tooling, and give researchers access to live PCC nodes in research mode through the Apple Security Bounty Program.
