Why can't I stabilize at 4.2? - Page 2

post #11 of 20
Set the multi at x2 reguardless, Higher RAM MHz results in a less stable O/C, your timings seem relaxed enough. NEVER do auto.

Yeah I think my RAM was holding me back. I have the multiplier at 2.00 now with 1:1 ratio, and it seems to be stable running Orthos. I'll just continue to increase the vcore little by little. Thanks everyone +rep.

That sounds good. They seem to hit a wall at around 4.0ghz. For your info. The max vcore for the Intel E8400 is 1.3625. Intel put those specs out, and said anything above that would probably reduce the lifespan of the CPU.

Actually your wrong, Absolute (Though not recommended) is 1.45. See HERE View the "Electrical Specifications Page..... (Roughly Page 17)"



With that said, If I had a E8400, I would probably run a max of 1.4v Idle

Yeah, I have mine under 1.3625 right now. What's your vcore running 4.0ghz? Also what are your temps? I have mine at 1.275 at 33°c idle.

So if my vcore was set at 1.318, would that reduce my cpu's lifespan by a lot, a little bit, or not at all?

1. My CPU can not achieve 4.0 GHz.
2. 1.318v 24/7 Is way under anything that would harm your CPU.

Ran Orthos for 8 hours and 50 minutes stable at 4.2ghz. Turned down my RAM multiplier to 2.00 so running at 1:1 ratio and just raised the vcore to 1.33 in the BIOS, but CPU-Z reported it as 1.312, and then ran Orthos, and the vcore stayed at 1.312, so not that bad of a vdroop. Anyways, I'll probably try lowering the vcore some more tonight, hopefully it'll be stable. Thanks to everyone. Wish me luck.

Wrong, See here, under VID voltage range. 0.85v-1.3625v. 1.45v is the absolute maximum voltage outside of the processors functional voltage range

As long as I can keep it under 1.3625 and 70°c load, I consider it okay.

Yeah, you're fine with anything below those 2. My E8400 acted funny after 1.4v for about a week. That 1.45v Intel put out is absolute max and is already far out of spec.
