As it says, Questions on a dual L5639 build.

I've seen cheap L5639 cpus, well theyre ES versions of the chip, and was wondering are they worth building up a setup using something like the budget Asus Z8NA-D6 board?

I seen someone on here has one, with "upto 119k ppd" in there sig.

At 2.13Ghz, are they worth getting, even with the now purposed changes?

Also, while on the topic of the L5639 ES models, anyone use these type of chips?
 
If you're aiming to have fun folding then a i7-3930K will be faster and you can get a board + CPU for around $800. It will use more power though so it depends on your goals.
 
I recently acquired a pair of L5639 ES chips. I briefly ran them in an Asus Z8PE-D12X board at stock speeds. I believe I was getting ~95k PPD on a P6903. Though, I don't think turbo was activating. They are currently in an SR-2 running at 3.1ghz getting ~165k PPD on P6903.

I have not seen how the deadlines will change with the bigadv changes coming in January. I would be hesitant to build a system with stock L5639 chips until I know what the deadlines are changing to. It may be fine after the changes, but at stock speeds, they may be too slow to run bigadv.
 
They will turbo to 2.26 ghz when configured properly and as 60w chips, the whole rig can draw less than 200w.

I would be shocked if these weren't fast enough for bigadv post revision, but you never know. It really depends on how cheap is cheap, for anywhere around 200 they would be a good buy for sure. Much above that though and you get into the 350-400 range that L5640's occasionally sell for.

Running 4 L5640 ES chips in 2 of those asus boards, mine are little faster but as R-Type says they pull very little power, also i have had no problems compatability wise with anything - they work just like a full retail sample.

These wont do the new bigadv.

Yep, this is where Standford has to be careful with their changes. If slow 2p Xeons are allowed 16 thread bigadv then what is the harm in tweaking Linux and running them on a single CPU if you're returning them faster than the 2p?

The cpu's are $300. I have one now that I'm putting in my ud3r board, and have been considering just dumping the $600, I'm in Canada we're expensivce, for a 2nd and the cheaper ATX asus, and 6Gig of ram.

Or, is it hard to modiy my 650D to fit an sr-2 to get that overclock... The sr-2 is $500 as b-stock. I'm certain my silverstone da700 has the umph, i's still need 6Gig of ram to match my current 6Gig.
 
I've mainly seen 3.6Ghz, basically 17 x200

Honestly, if I get 1000 more ppd on it at the power cunsumption it should give, YAY to me.

I'm installing it this weekend, while I'm not the best OCer, I'm gonna give it my best.

17x200 is 3.4ghz, not 3.6. That is what I expected to get. However, my SR-2 did not want to post at 200 bclk. So, I'm running 195 bclk. Once I resolve my issue of turbo not activating i will be ~3.3ghz.
 
Depends on what stepping you get A0 or B1. I have both and there are differences for overclocking. My B1 l5639 outperformed my A0 l5640.

I have 3 pairs of spanish hexes and have had several others. In my experience the A0's overclock much more consistently than the A4 or B steppings. They seem to stumbled onto something golden in that first stepping.
