AMD Ryzen 5 1600 and 1600X CPUs Found With 8 Working Cores

Reports have surfaced around the Web that some users are finding their recently-purchased AMD Ryzen 5 1600 and 1600X CPUs, which normally would have six cores (and 12 threads, with Simultaneous mutlithreading) actually have eight working cores (and 16 threads) out of the box. Unlike AMD's decade-old Phenom series, in which some dual and triple-core processors could be unlocked to fully functioning quad-cores via a BIOS feature offered on some motherboards, these Ryzen CPUs require no special BIOS setting. The processors still run at the stock advertised clock speeds, and retain the 1600's 576kb of L1 cache. But with the extra cores available, the 1600 series processors are basically on par performance-wise with the corresponding Ryzen 7 1800 series CPUs. This is an incredible value for lucky AMD users, as the 1800X retails for nearly twice the price of the 1600X.

And lucky these users are, as reports so far indicate that most, if not all of the unlocked CPUs come from the same batch of silicon, manufactured between September 4th and September 10th in Malaysia. This may indicate a quality control issue at this specific AMD factory. Alternatively, AMD could be bolstering its stock of Ryzen 5 1600 and 1600X CPUs to meet the higher demand of the mid-range chip, by labeling 1700 and 1700X CPUs as 1600 and 1600X respectively. Whatever the reason, it is definitely a welcome surprise to fortunate AMD users. If you have already purchased a Ryzen 5 1600 or 1600X recently, simply checking CPU-Z or looking at your windows task manager will reveal whether you are one of the recipients of an unlocked chip. If you are looking to buy such a CPU however, perhaps second-hand, a Reddit user known as "Rigred" claims he has deciphered the serial numbers corresponding to this batch of processors, allowing prospective buyers to verify that the chip is actually one of the unlocked few.

No, it's clearly YOU who "don't get it". Let it go. Just let it go.

Why? If you don't believe it, don't believe it. It's like the bios trick to enable the fourth core on the old AMD three core models. Many didn't want to believe until motherboard makers actually made official bios updates to do it.
This is nothing like the implemented BIOs unlock feature

Sheep can believe what they please without actual evidence

I'll believe what i please as well

That's true.
Bcuz It was first discovered in Korea on September 26. Someone has already tested.
This address contains cpu-z&hwmornitor 1600 x core issue benchmark test information.

Not surprising since the six core Ryzen offer the best bang for the buck

Is this your continuing statement about not believing? The difference is that your screenshot is an obvious fake as the font you used for the "12" and "24" are different and don't match the size of the rest of the text. The other screen shots posted above are far more believable as they don't seem to have been doctored like yours. Sad, just sad..
EDIT; You also forgot to modify the caches..

Well the original forum post from korea had screen photographs showing cinebench and CPU Z benchmark + cpu and cpu box photographs. this does not prove that the 8C/16T thread 1600x's are real, but if they aren't the "scam" was a little more elaborate than changing some numbers on a screenshot.

Let's wait to hear from AMD on this one. Besides, if this were a scam, what could possibly be gained?

AMD will deny it, I bet. Just to troll the entire hardware sites and forums?

They haven't done that in the past. If they don't chime in, they'll likely just stay silent.
