Testing under SingleStage:

 

this cpu really sucks monkeyballs - 53x100 = freeze during windows load, max boot 52x100 ... what a crappy piece ^^

Costa Rica chips seem to of been sucking serious balls so far.

Costa Rica chips don't seem to be any different than other ones... just random as ever

Some are good some are bad...

If its limited to 50x then cold doesn't make a difference...

3049A287 Costa Rica 1501 got here today. Will report back later when I fire it up in the UD7.

 

So far only x54. Gotta try a couple other BIOS though.

Probably limit if you already have PLL overvoltage and are running up the volts with 2c2t already.

Very true but Cowie is still on F2 because he says he can't boot past x53 on any of the B3 betas. I need to actually test F2 and try two other betas.

All on ss cooling, seem like 3 batches need less vcore comparo to L0 batches

 

Finally came face to face with the dreaded post code 00 (MIVE) on one of my really good chip:(

after reading about all this Malay,Costa Rica chips i think this is appropriate to post;

http://forums.anandtech.com/showthread.php?t=750461

I posted it this in the mammoth Northwood thread, and Wingz posted it in GH. I thought I'd post it once more just for the extra exposure.

 

 

Just to clear something up, the markings on the back of the CPU refer to the packaging site - not the manufacturing site of the actual silicon chip itself. Intel has no fabs in either Malaysia or Costa Rica, they are packaging facilities. The silicon die/chips are manufactured elsewhere in the world and are shipped to either of these two packaging sites. In addition, Intel manufacturing has a goal of running a "virtual fab" - meaning that, among other things, products from one fab are statistically indistinguishable from those manufactured at another fab. So even if, for example using fake names, Malaysian packages used chips only from fab #1 and packages marked Costa Rica use chips from fab #2, there should be no difference statistically between these two.

 

I saw these discussions back in the Celeron days, and I commented back then, but this time around it seems a little different. I have started seeing some online retailers charging more for parts from a specific packaging site and this disturbs me. There is no difference between parts from these two packaging sites. Just as you can have 6 head/tails coin tosses come out heads, there may seem to be a correlation that heads is more likely than tails, but there isn't. In reality the odds are still approximately 50/50.

 

The silicon is what defines the speed of a CPU, not the package. And the silicon comes from multiple fabs scattered all over the place that are all supposed to be identical anyway.

 

If you are considering spending more, or buying from a shadier vendor, in order to get a specific package, I would urge you to reconsider. There is no difference and you are only wasting money, and or risking getting ripped off.

Can't boot Win @ 5.1 GHz (51 x 100)/1.5 V(+) at air with P8P67 (PLL OV enabled), so no further testing - max frequency is probably even <5 GHz.

maxed out at 5288, no 1 MHZ more

 

 

p.s. with temperature below -15/20° C it act weird and lose about 200 MHZ.

the only good thing is that it's damn strong, I've abused it for more than 30 hours with vcore 1.7 volt at air cooling and still no sign of degrade.
