New 2500K, how's my vid?

post #1 of 26
Thread Starter 
Just tossed in a new 2500K I got. I launched core temp and noticed the VID changes? I'm switching from lga 775 where the VID always stayed the same in core temp. Anyway, I ran prime95 to test it under load and the load VID is 1.256v ... I was wondering how that was (or if it even makes a difference to overclocking in this gen??). I guess I could still return it and swap it for another one if it's bad. thnx

Would be nice to know how you idle volts are.

It keeps jumping around, but about 0.96 - 0.98 in core temp ... in cpu-Z it jumps around even more from sometimes as low as 0.728 to 0.968

Thats normal and dont rely on the voltages that core temp shows. There are grossly inaccurate. Typically your processor should idle between 0.8-0.96 v and at load it should be ~ 1.18-1.2 v.

I didn't know that, lol. Last gen (775) it was the other way around. I just re-did the prime95 stress test with cpuZ this time. It's around 1.176 - 1.184 ... I don't want to push this thing too much until next week when my waterblock adapter comes in. But just want to make sure this isn't a bad chip before my return period ends.

Running now. How long should I test it for? I'm still on stock cooling and don't want to push it too much. Been about 10 minutes so far and prime is showing no errors ... but my temps are around 73-78c depending on core. I didn't know what all the other settings were, so they're all still on "auto" except for the 1.18v and 40 multi

Needs to pass 12 hours custom Prime blend to be stable. Custom blend, hit the blend button (but do not start), then hit custom and put in almost ALL of your RAM (if 8GB put in like 7000MB to use). Let that run for 12 hours.

You're fine up to about 85*C. The fact you're doing 4GHz on the stock cooler is awesome.

lol Do I really have to run a 12 stress test just to ask what good vids are on these chips, which in all honesty doesn't even take knowing my vid to answer. How about this, let me rephrase my question:

What are considered good, average, and bad vid ranges on the 2500K chips ... or does that just not matter on these chips as much as they did on 775?

Nice That pretty much answers my Q I guess on whether I'll keep the chip
