I've been a long time reader and have finally came across something intriguing enough to post.
Recently, I acquired an E6300 engineering sample and I was wondering if anyone could tell me anything about this particular processor that I don't already know.
I would take a picture of the CPU but I've already put on the HSF and do not want to bother with reapplying it, however here are the markings on the IHS I wrote down before I did some googling:
INTEL CONFIDENTIAL
QHEF ES A4
80557PH0364M
There were a few more numbers on a line after the 8** line that I did not write down, if they are particularly revealing I will take the HSF off.
In general and from what I understand that the ES obviously means engineering sample and A4 is most likely the stepping. I also under the impression that A4 is equivalent to B0 stepping and has an unlocked multiplier. I have not checked if it indeed has an unlocked multiplier as I have never encountered a processor that has one nor do I know for sure how to check. If anyone would care to enlighten me it would be appreciated.
From the next line I have figured the 3 means it is a E6300 (which I already knew). The most perplexing bit is the 4M, which I take means a 4 meg cache which is most certainly not a feature of the E6300.
So, this processor seems to have the best of both worlds when it comes to engineering samples. This all seams rather unbelievable to me, and my first assumption is for any readers to think that my post is falsified, but I assure you it is not. My technically inclined friends are in shock and awe at this processor as am I.
Bringing things to the present I borrowed some memory to complete my Core2 system in-the-works so that I could bench and CPU-Z this processor, the CPU-Z results confirmed most of my suspicions, however I am curious as to why this processor would have all 4MB unlocked, and be marked Conroe as opposed to Allendale (I thought CPU-Z always said Allendale for E6300s). My only guess is it is a universal Conroe able to be changed by multiplier to any processor in the Conroe family. This would also semi-explain why it shows up as a Pentium D in the BIOS/CPU-Z as the identifying data in the processor would be absent (this is my speculation). I am also wondering why the stepping is reported as what you see.
I also ran Super Pi Mod as you can see. The memory may have had a negative bearing on the score, though I am not sure. I mainly ran this so someone could tell me if the scores check out for a E6300 running at stock.
The memory I borrowed is pretty cheap stuff (Kingston DDR2 533) so I won't be overclocking this system yet. I have some G.Skill DDR2 800 CL4 on the way and will be juicing the system with it. If anyone would like to give me some pointers that would be great. My motherboard is a GA-965P-DS3 Rev 1.0 with Bios F9.
