2600K folding rig and PPD numbers

[zoob]

Here is my comparison (finally both boxes received the same project):

P6901 running on Win7 X64
i7 970 @ 4250 MHz (25 x 170, 1.43xxV BIOS, LLC Enabled), TPF 20:44, PPD 64786, PPD/MHz 15.244, ~305-310 W from the wall (measured this morning)
i7 2600K @ 4800 MHz (48 x 100, 1.405V BIOS, LLC Ultra High), TPF 25:05, PPD 49024, PPD/MHz 10.213, ~225-230 W from the wall (rough approximation from memory)

Both running Corsair Vengeance DDR3-1600 9-9-9-24-1T, though the 970 has it clocked at 1700 9-9-9-24-1T because of the dividers.

John, what timings do you have on the RAM for your Sandy setup? I wonder why mine has a longer TPF. :/

EDIT: Added power consumption approximations
Main differences:
i7 970+EX58-UD5, 3x2GB RAM, uses an XFX HD6950@HD6970 2GB, with CPU aircooling Prolimatech Megahalems + Gentle Typhoon
i7 2600K+P8P67 DLX, 4x4GB RAM, uses a Gigabyte GTX560 Ti SOC 1GB, with CPU watercooling (DDC3.2 + 4xS-Flex fans)
Both are powered by a Corsair AX750

Nice clocks on both chips. Do you have a power draw comparison?

I got this : at 4.6Ghz with 4g of Ripjaws 1600Mhz 9/9/924/1T.
Im not able to OC my ram, my pc crash /freeze each time...

Project ID: 6900

Min. Time / Frame : 00:25:53 - 46*768,8 PPD
Avg. Time / Frame : 00:25:54 - 46*723,7 PPD

zoob, are you using linux or a VM for either of those?

I'm using Linuxrouter's image, w/ VMPlayer 3.0.0, I remember seeing ~55k for a 6901 at 4.84GHz (47x103). Ram is running slow at 1376, but a tight 7-8-7-21 1T.

@Zink, added power consumption. 2600K is approximated from memory

@lowfat, Win7 X64 SP1

@3.0charlie, ahhh that makes sense!

My TPF actually went down slightly, maybe by 30 secs tops each after I let the computers crunch undisturbed overnight (close down all apps except for FAH). I'll give VMPlayer a go. Maybe this way I won't have ruined WUs if I break out to play some Crysis 2

I'll have to disassemble both rigs tonight unfortunately, as I recently got my B3 board, Noctua D14, and new RAM. Since the Sandy rig needs an overhaul anyway, it's going back on air. The 970 is craving for water.

[3.0charlie]

My SB pulls ~235W (per the APC app.). And I'm doing the opposite - going from a TT Frio to a Swiftech setup... 80C under load w/Air is amazing (HT on), but a tad too high and noisy.

I finally reached my goal of 60 000+ ppd on my main 2600K folding! Woohoo!

WU 2692...haven't got that one yet.

edit: Nice PPD though.

It takes my 3.6ghz i7 36min do each frame on those so not quite twice as fast but close. It's been stable for all those 16 frames at those clocks?
