![]() ![]() From my overclock above, however, I’d be willing to believe that it’s true. It’s been rumored that Intel made minor changes to the i7-975 to improve overclocking, but it’s hard to say for sure without touching many different samples. Even at 3.7GHz however, it was completely stable with LINPACK testing for hours, and that in itself is impressive. Even more surprising was benchmarking Cinebench and 3DMark Vantage many times over, only to retain full OS stability.Īfter some investigation, it turns out that the CPU was indeed throttling due to temperatures, and in Cinebench, the CPU would drop down to around 4.0GHz, whereas with a more robust benchmark like LinX, it’d drop to 3.7GHz. The overclock you see above is the absolute first one that I tried, and when it successfully booted into Windows, I almost dropped my jaw. However, from what I’ve seen at Computex thus far, 4.0GHz stable is not an unreachable goal on the i7-975, not by a long-shot. Normally I like to show a fully 100% stable overclock, but given the temps I received, it’s really difficult to keep temperatures in check even at 3.6GHz. As I’ve mentioned in many other CPU reviews, a huge limiting factor for me is overclocking in a warm room, and as you’d imagine, heat doesn’t go too well with that. Overclocking Intel’s Core i7-975 Extreme Editionĭue to various factors (namely Computex), I didn’t spend as much time overclocking the i7-975 as I would have liked, although it took me no time whatsoever to hit an amazing clock. If both these CPU and GPU tests pass without issue, we can confidently declare a stable overclock. If this passes, some time is dedicated to real-world game testing, to make sure that gaming is just as stable as it would be if the CPU were at stock. To test for this, 3DMark Vantage’s Extreme test is used, with the increased resolution of 2560×1600, looped nine times. If the CPU stress passes without error, then GPU stress-testing begins, in order to assure a system-wide stable overclock. Generally, if the CPU survives the first half-hour of this stress, there’s a good chance that it’s mostly stable, but I strive for a 12 hour stress as long as time permits. Also, despite its name, IntelBurnTest is just as effective on AMD processors. Compared to other popular CPU stress-testers, IBT’s tests are far more gruelling, and proof of that is seen by the fact that it manages to heat the CPU up to 20☌ hotter than competing applications, like SP2004. ![]() Linpack by Intel is an extremely stressful program that will put even the most powerful X86/X64 CPU in the world at. Downloaded: 306,082 times (504.2 GB) A program that simplifies the usage of Intel Linpack. How we declare an overclock stable is simple… we stress it as hard as possible for a certain period of time, both with CPU-related tests and also GPU-related, to conclude on what we’ll be confident is 100% stability throughout all possible computing scenarios.įor the sake of CPU stress-testing, we use IntelBurnTest, for reasons I’ve laid out in a recent forum thread.

As I’ve mentioned in past content, I’m not as interested in finding the highest overclock possible as much as I am interested in finding the highest stable overclock. TUF RTX 3090 Ti OC weve got here runs at an average 1,990MHz in our 4K Metro Exodus long-term stress test.
