His processor didn’t even hit 100°C—it was only 99°C, and it slowed down. I’m not sure if the issue was with the chip itself or the cores. Since we can’t push it to 4GHz anymore, the temperature shouldn’t be a problem. He’s been looking for a more effective cooler.
At 4Ghz it doesn't power on even with just 1.5V, it jumps straight into "Failed OC... Press F1....". It seems the 3.8V might still work. I also considered whether the motherboard could be the issue—maybe insufficient VRM power. It has 16+2 phases, which isn't necessarily better quality, but it's an ASUS model and should be fine. Since it wasn't warm, the problem likely isn't the motherboard, unless a faulty CPU is involved.
There might be several factors involved, like adjusting the memory divider at higher reference frequencies.
By "memory divider" you likely refer to the memory speed setting, such as 1T or 2T. It doesn't specify RAM command rate but describes how fast the RAM is accessed.
The memory strap, also known as a divider, is used to lower the speed. Which board are you referring to?
I'm not really in a position to test it yet, being about 35-40kms away. I think I'll wait a few months before trying it with the cooler he ordered. Still, I'm interested—maybe it really improves performance with a better unit, since the one he has now is basically a DIY build (a solid heatsink, an Intel stock fan, and zip ties).
Currently I rely on an older CPU mainly for overclocking, using an I7-920 at 2.67Ghz with D0 stepping. With a solid motherboard (Asus P6T SE), I managed to push it up to 3.7Ghz at around 1.10625V, but reaching 4Ghz requires 1.25V. Pairing it with a Deepcool Gammaxx 300 cooler, I'm amazed at how well it performed back in 2008.
