Bit-Tech p55 first look

[Yakyb]

Although we've spent a lot of time benchmarking and overclocking the Asus P7P55D Evo, we promised Intel that we wouldn't reveal any performance results just yet. However, we can say that the Asus P7P55D Evo and the (non early Engineering Sample) LGA1156 Core i7 CPU perform extremely well and are very easy to overclock well beyond their stock frequencies. Having seen what the LGA1156 platform is capable in terms of performance it's clear that both LGA1366, but more importantly Socket AM3, will have a real fight on their hands later this year.

In terms of overclocking, LGA1156 CPUs behave in the same way as LGA1366 CPUs - to overclock the CPU, you need to increase the QPI/baseclock from its default of 133MHz. Once again we can't got into specifics, but with the aforementioned Cooler Master Hyper 212 cooler and a not unreasonable amount of extra voltage we could stably benchmark our test CPU with at least a 1.2GHz overclock on all cores.

In conclusion, the Asus P7P55D Evo shows a lot of promise, and while Asus was unable to confirm the price, given the positioning of the Evo brand beneath Deluxe, it's likely that the first LGA1156 motherboard will be competitively priced.

I still don't understand the retention bracket of the LGA 1156 socket XD

[Kai Robinson]

I dont understand why Intel couldnt have just stuck with a single damn socket design. This is going to end up like Socket 940 and Socket 754 all over again...

Intel foistered a server product onto desktop users and are now bringing out a desktop product.

The desktop product will allow for lower pricing than the server product is capable of.

nice

it seems like I5 overclocks at least as well as I7. And considering that they will have a lower TDP 95W, 4.5-5ghz will be reacheable on air... And i hope that theese motheboard P55 will have a higher BKL wall.. Anyway very good news..

Simplicity definitely has its appeal, P55 boards are damn sexy looking!

They did, replacement for S775 is S1556, S1336 was replacement for S771.

Hardly.

Socket 771 was never marketed as a desktop solution (well, Skulltrail, but even that was fairly high-end workstation rather than desktop).

Socket 1336 on the otherhand is being pushed by everyone as high-end desktop.

2.660ghz + 1.2ghz = 3.860mhz ?

So whats the problem, S1336 is server/workstaion grade. The number of sockets is the same. We get replacment for mobile, consumer, server/workstaion, MP/HPC platform.

The topend S1156 will perform better then even a QX9650, QX9770.

The only thing that intel did, was to split the enthusiast market form the mainstream market. Consumers didn't care for S1336 (as seen that the dualcores on S775 are still strong) anyway.

[Clairvoyant129]

There goes the argument by AMDroids that LGA1156 CPUs can't overclock.

But S1336 hasn't been marketed solely as a workstation grade processor, it's been marketed as a high end desktop. It's also been the only way to get the next-gen i7 processor for nigh on a year, and now they're releasing a different socket.

With Core2, there was a clear distinction between server/desktop and mobile segments which was based on socket. Now you have this blurring of server into desktop, and no alternative if you want the new microarchitecture.

I know it's hardly the end of the world, and it's probably not really worth arguing about, but it does complicate they buying decision for a lot of people, myself included.

Ho, ho, ho, someone broke their NDA. 200 base clock at 1.672vcore makes me cry.

Is CPU-Z wrong or now you can set the Uncore clock under 2x Mem clock?

[Smartidiot89]

Is that voltage correct?

[HKPolice]

There is no way that those vcore readings are accurate. Please link to the original thread with actual voltages.

[Chri$ch]

Uncore = 3 x mem clock (not 4 x as on LGA1366 CPUs)

Is that voltage correct?

Yes, but as i asked if they need this voltage he said

just for easy tune,no need much

[HKPolice]

So what does that mean, he intentionally overvolted by over 0.3v because he didn't want to bother with voltage tuning?

[clonez]

1,744v for 4,5ghz on i5

i hope that isnt correct...

edit:

lol, so he actually gave the cpu that vcore and only got THAT?

wow, 1,768v for 4,6ghz
shouldnt it get fried with much lower v?

[trans am]

What cooling? Just air? Did he just crank the max vcore the board would allow and cross his fingers?

so what... for quick and dirty runs noone care for the acutall voltage.

[clonez]

but it isnt only a bit higher than i7 runs...

wonder cpu, that it even runs long enough to make pics

[Chumbucket843]

well i dont think that vcore is right because it said in the article that the cpu idled at 36c and load was never 60c. about their OC, bit-tech sucks at overclocking. the only cpu they got over 4 ghz lately is i7 975 and 965 and that was with massive vcore
