and running a couple P1's
and an LL of a 56 million number @ .021 seconds per iteration.

temps are stable with intel's stock air cooler. I played with the Gigabyte auto-overclocker application a bit, but it didn't seem to improve times much.

Those are pretty good timings.

Those timings are about what I get with a i7-2600K slightly OCd to ~3.8-3.9GHz, so it does seem there is a slight IPC improvement, but not much.

A full benchmark with 27.7 would be nice. It would be nice to compare it with a sandy bridge of the same clockspeed.

I hope that tomorrow my i5 3570K will be delivered. I will use a Corsair H100 water cooling and will post my results here. Additionally, I bought new Corsair DDR3-2000 MHz CL9 RAM as Prime95 version 27 is memory bound.

Those are good times for a 3.88GHz! I got approximately the same for a sbe (i7-2600k) OC'ed around 4GHz too. For higher FFTs the memory (speed/channels) also come in play.

Jeff Gilchrist · 2012-05-07, 15:52

I'm looking at putting together a new Ivy Bridge system with mild overclock, nothing too crazy on air.

What are decent cases these days, power supplies, etc...

I'm interested in one of the new Asus Z77 motherboards since I heard that they did some interesting work with the memory subsystems to increase performance. What speed of DDR3 should I be looking at now, I think Z77 can support up to DDR3 1866? Is Corsair still a good RAM manufacturer?

I'm not trying to build the cheapest possible system, but want good quality parts.

The RAM goes passed 2133 if I recall correctly, though over course anything over 1600 is technically overclocking (still better than 1333 for SB). I remember hearing about the ASUS memory thing, but haven't heard anything since the initial review (haven't really looked either to be honest). As of last year Corsair and GSKILL were probably the biggest names, followed by Kingston. I'm sure the others are mostly good; have my sticks are Mushkin, but that's at 1333. For awesome/cheap air cooler, the Hyper 212+ is always a gem. It costs $25 and got 25C lower temps than stock/piece-of-junk heatsink. (Still reporting for SB of course.)

Redarm · 2012-05-07, 16:19

Some Z77 boards supports SSD-Caching, the only thing i know which could be important for some things

perhaps these RAM-Modules could be interesting for you

high frequency + better timings + 1.5V support

That's a darned nice video -- adjustable desktop TDP for the win (not-GIMPS-withstanding

). I haven't even got to the memory part yet, but ASUS is looking pretty smart

Edit: Memory is at 28:45.

LaurV Romulan Interpreter Jun 2011 Thailand 10010110111001₂ Posts	Those are good times for a 3.88GHz! I got approximately the same for a sbe (i7-2600k) OC'ed around 4GHz too. For higher FFTs the memory (speed/channels) also come in play. Last fiddled with by LaurV on 2012-05-07 at 03:01 Reason: stupid, there is no i7-200k :D

Jeff Gilchrist Jun 2003 Ottawa, Canada 3×17×23 Posts	I'm looking at putting together a new Ivy Bridge system with mild overclock, nothing too crazy on air. What are decent cases these days, power supplies, etc... I'm interested in one of the new Asus Z77 motherboards since I heard that they did some interesting work with the memory subsystems to increase performance. What speed of DDR3 should I be looking at now, I think Z77 can support up to DDR3 1866? Is Corsair still a good RAM manufacturer? I'm not trying to build the cheapest possible system, but want good quality parts.
