P55 Overclocking Showdown - ASUS, Gigabyte, and EVGA at the OC Corral (Page 6 Updated)

Max CPU BCLK and MHz
We used a 750 CPU for this part of the test, comparing maximum attainable BCLK using a 17x multiplier, maximum overall CPU clock validation using the same multiplier and finally the maximum Super Pi 1M pass frequency. The reason for using an i750, well, our two 870s did not survive due to the socket burn problem and before we torture our replacement processors we would like some assurances it will not happen again. As such, i750 results for the ASUS board are missing until we receive a replacement board.
Note that using a lower CPU multiplier of 17X the Gigabyte board manages to beat the EVGA boards by 2 BCLK for outright CPU-Z validation and the EVGA P55 FTW by around 8 BCLK for Super PI 1M. At 21X however, that initial promise of higher ‘validation stable’ frequencies does not translate into higher overall overclocks even in light load benchmarks like Super Pi 1M.
Although we managed to get a 1M to pass at 233x21 on the Gigabyte board, every time we tried to open CPU-Z to capture a screenshot, the system would crash. In the end we had to step down to 229X21 at 9-9-9-24 memory timings in order to get a screenshot with all relevant CPU tabs shown. This left us scratching our heads because at higher BCLKs using the lower CPU multipliers, the Gigabyte board showed better overall stability for validation and Super Pi 1M when pushed over 245 BCLK than the EVGA P55 FTW.
The EVGA E659 was a disappointment in this section of our testing too. Our maximum Super Pi 1M came in at 21X228 BCLK, while max validation stopped at 231 BCLK, trailing both the cheaper EVGA 657 and Gigabyte P55 UD6. This leaves the E659 as a board capable of lower stable memory speeds than the other boards in our testing with its one strength being 8-thread non-memory intensive system loads like WPrime 1024M.

Just wanted to comment that I just ordered a EVGA P55 SLI (NOT FTW) from newegg and received a foxconn socket...Though on the forums, the evga reps are insistent that there is no problem with their boards.... Who knows if I even have a revised socket........
ARGHHHHHHH

Saw recently a number of boards from asus and gigabyte with Usb3 and Sata 6gb support.Are you guys planning to include those boards in your upcoming p55 board reviews?groove420 - Saturday, November 21, 2009 - link
The new Gigabyte boards will be designated as "P55A-UD6" for example, along with a "333" designation on the box.The feature that caught my eye on these is that they have been refitted with a LOTES clamp instead of the Foxconn.
They remain fitted with a Foxconn socket apparently though.
Whether the fix for the "hot socket" was just a better clamp, or indeed the socket is a revision as well remains an unknown from what I've gathered.

Think they went with the more afordable way to change the clamps than the entire socket.got to wait and see if it pays out..incase those who are willing to buy decide to dump $$$$$$$$ in thatArbie - Monday, November 9, 2009 - link
"Be warned the results are geared more towards benchmarking fanatics and are not in any way indicative of your everyday web browsing PC needs... "Is this a benchmarking fanatics website? Or is it aimed at folks who want high-performance gear for day-in, day-out use? I am in the latter group, which is why I visit AnandTech practically every day. But I won't even bother clicking through a report like this.
In fact, probably only 0.1% of your readers are going to build on the edge (sub-zero cooling?), and there are plenty of websites for them. I'd rather see the same time and effort spent on something more relevant to the other 99.9%.
My opinion...

I happen to agree 100% - I am interested in the high-performance gear for day-in, day-out use idea.Anybody who wants Lynnfield for breaking OC benchmarks is wasting their time.

99% of the articles here are for regular users. This happens to be an article that is not for everyone. So what's the big deal if the minority audience occasionally gets a hearing every now and again? When I see articles like this going up every single week I might start to ask questions, but not before that.AstroGuardian - Wednesday, November 11, 2009 - link
Guys and gals,This article is 100% for everyone despite what other ppl say.
You are totally missing the point of this post. This post is not about manufacturers and main boards. This post is about P55!!!
I am sure everyone (including benchmark fanatic) would like to hear about P55's capabilities. This article says about P55's abilities and gives insight about possible scenarios when pushing the P55 to its limits.
So what do you want to say? Do you criticize this site or what? Not all of you are IT professionals. As a matter of fact so few of you are IT professionals. And as professionals you musk know as much as possible about your area of expertise. I would like to know everything Anandtech has to say about everything. That's the beauty of it

+1. I rarely overclock myself but I still am interested in what the capabilities of this CPU/chipset combo are. I like seeing systems pushed to their limits until weaknesses become apparent. Extreme overclocking in my opinion is like stress testing... if there is any weakness in a design overclocking can expose it. In this case it could be the Foxconn socket, the lesser number of pins on the CPU itself (compared to previous gen i7s), the interface, or all of the above.
