Well, I figured I could try it a little. 🙂
Here’s what the chip says:
A1333AMS3C
AYHJA0119FPDW
Y6350640329
The CPU came courtesy of Robert Hodge from iComPz.com. Roger basically started overclocking a few years back, and he liked it so much, he built a business.
He was one of the first to tell me about the AYHJA, and very kindly offered to send me one.
I had a very nice chat with him a few days ago about a number of overclocking topics, but what impressed me the most was an email one of you sent me.
iComPz had sent out about a dozen of these processors until they realized they had something new.
What they then did was send an email telling those getting the new processor what they were getting rather than the AXIA, pointing out that this one looked better based on their tests, and offering the buyers a $10 credit due to the error.
One of you sent me a copy of the email asking, “Does it sound on the up and up or are they spoofing me?” It was a nice change-of-pace to say it was quite legit. 🙂 Now that I would call customer service.
Anyhow, to make a long story short, after proving to myself that the watercooling system was going to pot, and putting in an Alpha PAL6035 (which had come from PCNut), an old standby, I ran a few tests this morning.
The big news on these AYHJAs is significant power reduction.
Using an AXIA, week 10, I was getting a maximum temperature of 53-55C running Prime95 at 10X133 at 1.78V. Under exactly the same conditions, the AYHJAs are coming in at 47-49C.
For that matter, I was getting slightly lower temperatures running this chip at 1500Mhz, at 1.85V, than I did from the AXIA at 1333Mhz/1.78V.
I won’t swear to this, but a little back-of-the envelope calculation tells me that this is roughly equivalent to the power reduction expected from Palomino. Update: I’ve been told by somebody that this is rather a further implementation of ACPI. Asked a few questions about this, we’ll see.
I should note that the Palomino we saw with a code also had five letters and also had an “H” in the middle. I’m not saying these are Palominos in disguise, they aren’t, Palomino have a different, bigger shape. However, I think it’s reasonable to believe that these processors could well use the same power-reducing technologies that will be found in Palomino.
So what does that mean to you?
It usually means you can run faster.
That doesn’t mean, however, that you still don’t need good cooling.
With the Alpha, Prime95 was no problem at all, maximum temperature of 53C using 1.85V. Forget 1500Mhz and Prime with the AXIAs, at least on this machine.
1575Mhz almost works in Prime95. If I had better cooling, I’m awfully sure it would work.
Once I get my hands on better cooling (or if those of you with ideal cooling get your hands on one of these CPUs before I get my hands on the better cooling), I’ll tell you how I do, but I can tell you right now this chip is an improvement over an AXIA.
Improvement enough to dump your AXIAs. Well, I don’t think I’d go that far. Nor would I say that those who are and can wait for Palominos should stop waiting.
But if you’re looking for a TBird now, you ought to start looking for AYHJA on your CPU.
Again, thanks to Robert Hodge from iComPz.com for making this discovery possible.
