I haven't tried higher or lower yet but it is the best one I found so far for 5Ghz speed. I was surprised that they had 3 Costa Rica's sitting there.
Are you for real ? Costa Rica's chips ? Really ? Didn't you read the 5th post above you ?

By the way 1.42v for 5ghz is pathethic.

Ok, going to go through about twenty pages, will return with all updates.

++UPDATE++

All added that met guidelines. Some need to read the VERY SMALL set of rules, one of the most important is SCREENIE UNDER LOAD.

Everyone added, sorry for the wait, but get them tags on.

hey guys i'm wondering if you guys can help me find a BSOD problem that I have. Basically I BSOD once a week, maybe less frequently, and I don't know why. It only happens when theres no load on the cpu, like I'm reading a webpage or something. I am in the 5ghz club prime blend 1hr stable. Here are quick specs

P8P67 PRO B3 revision 1502 BIOS
2500k
G.Skill Ripjaws X 1600mhz CAS9 8gb

Internal PPLL Voltage = ENABLED
Load Line Calibration = Ultra High
VRM Frequency = Manual at 350
Phase Control = Extreme
Duty Control = Extreme
Vcore = 1.525v under load (MANUAL, not offset)
DRAM Voltage = 1.50 9 9 9 24 2t timing (factory recommended)
VCCSA & VCCIO, everything else AUTO
C1E, C3, C6 = AUTO (this I noticed changed from previous BIOS)
EIST = Enabled

when sandy bridge first came out I bought the board and the cpu...made it to 5ghz no worries and have been fine since. The only differences I made since then, is a B3 revised board and a 1502 BIOS flash. What do you guys suggest I do? The weird thing is, the BSOD only happens when theres no load on the CPU. Like I said, reading a webpage or just browsing the internet. Never happened during a game

thanks in advanced!

Using manual or offset voltage? I had stability problems with offset so I switched to manual. Zero problems now. If you insist on using offset (saves < 5w at idle) than you may need to raise vcore a little more than you would ordinarily need for Prime/LinX to find idle/low load stability.

You could also try setting your other voltages to the default manually instead of using auto. Some boards under/over-volt some things on auto.

Also, 1H prime blend is no where close to what you need for 24/7 stability. I would recommend 8-12H of prime blend for 24/7 stability and/or 20-50 passes of LinX with updated Linpack (with Win7 SP1). You'll probably find you need too much voltage for this and need to back down the speed for 24/7 use.

I'm using manual voltage. And this rig is not a 247 rig, its only on for about 5-6 hours per day for games, internet

I'll try manually inputting the other voltages to default values, instead of leaving it in auto. But the thing is, I never had issues with 5ghz until recently. And the only things I've changed are B3 revised board (free under recall by Asus) and flashed to 1502 BIOS. I have a feeling that one of these two differences might be the culprit. But I wanted to get everybody's opinion on it before I make any changes

May just need a bump in Vcore then.

Sounds like someone (Droid) got a fail chip and is jealous.

BTW mine is also 1.42v load for 5 ghz. (thanks to the new F3 bios, get to use 1.440v BIOS LLC6, for 1.424v load but keeps dropping to 1.404v sometimes)

I have a new build and new chip to update my previous submission.

So far this chip runs hotter but at lower volts. My new rig has proven better cooling, it ran my chip that I submitted previously ~3c cooler. But this chip is hot. This is not the lowest vcore I can get with the new chip and will work towards lowering it. The p67a deluxe is overclocking differently than my old MSI, for instance the asus wants to run with turbo enabled to be stable. With turbo disabled it would not run prime at this voltage for 3 mins before BSODing. Once turbo was enable it was completely stable.



And here is the same chip booting at 5.6ghz with all cores enabled and HT on.



This is a great chip, however I would be open for a trade with someone's 2600k that reqs less volts for 5ghz stable with HT on regardless of its max multi.
