Having 700-800w of heat coming from 5 gpus right next to you is definetely something the folder in me just loved...

I must say--two GTX470s put out a lot of heat. The two 460s do too, but considerably less. Still more than enough to heat up my ~120 sq ft dorm room

I must say i can't wait to play with the little pentium. Time to really see if 12 threads is SO much better than 2 really good one?

It should be noted that i hate Intel for locking down my cpu. Why in hell should i have to pay for playing with frequency and multipliers ??? I'm f*****g voiding my warranty here! I think i did my part.

The last part was purely emotional. My rationality understands all that pretty well, it just needed to be told to the world.

Really even the new Pentium Dual Cores feel wicked fast. For basically everything, my i7 is overkill. At this point a $75 CPU is more than enough, and a good SSD makes the biggest difference. I love the one in my laptop--night and day vs the 5400RPM disk in my i7.

I thought that this might be informative.I'm actually stunned by the PPD difference between my GTX 460's(@780 MHz) and my GTX 560 Ti's(@900MHz). The 560's are running at max PPD while the 460's have slowed down by almost 24%. There are 2 other factors that I'm too lazy to test. 1)The 460's are on XP and the 560's are on Win7. 2)The 460's are on an old A8N-Deluxe with an Athlon 64 3200+, the 560's are on a P7P55D-E PRO with an i5-650. I also know that one of the 460's is running core_15 v 2.25 while the 560's and the other 460 are running v 2.22. So, is it the old A8N or do all those extra specs on the 560 make that much of a difference?

[[Ion]]

That's way off. On the 5757pt WUs, I'd get ~16.2k PPD with my GTX460s (@848MHz). Something like 15.3k (IIRC) @ 750. I can't imagine that it's the old AMD A64--maybe it is XP though

Biggest ppd impact: core 2.25. That thing alone shaved 3500 ppd on a single gtx 460. Revert to 2.22 ASAP.

Next i would say mainly clocks and cores explains the difference, with a distant cpu power/pci-e speed mention...

Why is Stanford pushing out a new core that cuts performance so drastically? How is that possibly good for them?

I'd imagine that the clocks do have an impact--with the additional 3.5k PPD, he'd be at ~14.5k, which is low but not terribly so.

Better kepler support

Fair enough. So can the GTX680 then do more than a somewhat miserable 18k PPD?

[Feanor]

As you can see, i didn't said support. I said better support. SUPPOSEDLY, they do fare a little better. Nevertheless, it was such a pain finding what was stealing my ppd!

Grrrr. Just checked and both 460's are on 2.25. The process to revert to 2.22 is no fun and there's no guarantee it won't download 2.25 again.

As long as you don't re-install your client (delete the core), you should be fine. I did the revert only once.

Did you just delete the 2.25 core or did you follow http://fahwiki.net/index.php/Downloa...files_manually

Edit:I had "client-type" set to "advanced" and that CAUSES 2.25 to be downloaded!!!!!!http://foldingforum.org/viewtopic.php?f=74&t=22793

[Feanor]

It must be because i said i only did it once that my 4 gpu3 clients switched to 2.25 during the night...

Of course i did not had a 2.22 copy on hand...

[thebluebumblebee]

Update with 2.22 for all:

[[Ion]]

That is much better! I'm glad you got that sorted out!

Those GTX560s are really doing an amazing job! ~same PPD as a GTX470, but with (presumably) far less heat

[Feanor]

Buck, you should really come back to -bigadv : i was having heat issues, and while testing, i picked five 8102 in a row! That's 7 including the last two wus my sr-2 returned!

Already have one rig back on -bigadv, but got an 8101. Waiting for the other to finish up tonight with WCG and then both are back on F@H.

Remember, if your not running 2.25, you will not recieve the -beta unit. I'm gonna run a GTX460 for a week to see if I can pick up one or two. Currently getting 11,880 PPD with 2.25.

Bruce: are those 560's the 448 core model?

[theonedub]

Have you guys seen these new GPU Beta clients with Quick Return Bonuses? Apparently a 580 can do over 250kPPD on them (P8057), WU are in short supply though.

I don't believe that's true. I'm almost sure of it. 2.25 is only required for Kepler based cards. "I got one! It appears to run fine on v2.22 FAHCore_15. I'm getting 95,500 PPD on a GTX 460!"-P5-133XL

Nope, just GF114 560 Ti's

Must have been info I saw back when it was a closed beta. They were using the Kepler version of Fahtracker v2 that carried the -beta flag.

That's absolutely incredible. Once these go live, that would absolutely be enough for me to bring both GTX460s back to FAH

[BUCK NASTY]

Getting back into the swing of F@H with 3 dumps today for a total of 1.032 Million points. Still no P8102's in sight(Feanor hoarded them all). After the WCG Challenge is over, Norton will bring the Opty-6176 over for a visit. Keep on folding boy's.

[[Ion]]

Sweet!

I'm negotiating with KieX to buy a pair of HD7770s, in which case I'll probably bring some GPUs back to FAH

[p_o_s_pc]

I should have a GTX460 1gb next week folding for you guys, I know it isn't much but i will also throw in a 8800GTS G80 till it dies completely.(its been unstable)

Hey, a GTX460 can still get 16k PPD on the good WUs and at least 11k even on the worst ones

Dropped one today for 250k. And you know what? I got another one. That's 8 in a row...
