Core i7 Overclocking by Batch #

[JWMc]

Edited my other post with updated 4.0G info. Prime blend 11 hours successful at 1.3125v. QPIv at 1.225. DRAM at 1.6v. Everything else on Auto. Going to try 1.30v later today.

Very nice, I did try 1.3125v load @ 3.990ghz (190x21), 6GB, HT enabled, guess what!:

Yep, same result pretty much. I didn't do long term Prime blend testing yet but the vCore is verified for sure.

I love this chip I got!!!!

Fantastic JWMc, I was able to match same setting of yours at 3.8 Ghz @ 1.2V after I moved from BIOS F4r to F5e. That BIOS helped me drop voltages by 0.05V from 1.248V @ Load to 1.2V @ Load. I am pretty sure, my processor could match you voltages on 3.99 Ghz too. Seems 3841A is a very good one.

Outside the case, my i7 went above 70C @ 3.8 Ghz, but inside the case its running at 74C in Linx with room temperature at 26C. I can't imagine the heat at 3.99 Ghz when it will be inside the case at 26C Room temperature( probably in 90's).

Any temperatures above 80C, seems a bit high - as my PC turns into a heater thanks to CPU, Memory, Gtx260 and NB all contributing to the heat.

I was getting "IRQL not less or equal" error with Green Lan Feature enabled. I disabled that feature and the problem is Gone.

I'm sure it could, our chips seem like they might be almost identical. Are there many 3839s that are known to OC poorly? I've seen people say their 3841s didn't do well also.

About lots of chips hitting 4ghz on the Xtremesystems forums. I bet that's because we know how to test things properly and present/compare data honestly. I bet just about any i7 can hit 4ghz on air but many of us use water and many noobs on air aren't altering the test environment properly to see what it can do (super cold ambients).

Outside the case, my i7 went above 70C @ 3.8 Ghz, but inside the case its running at 74C in Linx with room temperature at 26C. I can't imagine the heat at 3.99 Ghz when it will be inside the case at 26C Room temperature( probably in 90's).

My in-case temps at normal ambient (25C) went WAY up compared to my early testing in the cold. But I have a bad situation where I only have one exit fan for the heat. I'm using a Sanyo Denki 101 for the single exhaust fan though so I can crank it up if I want to. Entirely new chassis and WC plans are in the works.

I was willing to push the CPU to 8-9c from TJMAX on air, no more. This was also only just to see what the chip could do so I'd have more information to decide on building my first WC loop or not. I'm going for low 60s in Real Temp @ 25C ambient for my max 24/7 OC on water, whatever that turns out to be.

I was getting "IRQL not less or equal" error with Green Lan Feature enabled. I disabled that feature and the problem is Gone.

I think I may have glossed over this in the Gigabyte X58 board thread. If this helps stability it could be important that everyone learns this!

I just tested with exact same setting of yours. Did 10 runs of 17000. It passed.

Only thing is the temperature was 87/85/86/79 after the run. On a completely closed Case (I shud have kept one side open) Room ambient was 25C.
