Looking in [URL="http://www.mersenne.org/assignments/?exp_lo=78100000&exp_hi=79000000&execm=1&exdchk=1&extf=1&B1=Get+Assignments"]here[/URL] the exponents given out are either TF'd to 74 or given to wabbit aka ForResearch aka GPU72, so everything looks fine.

Except that maybe currently there are too few P-1 workers so all the Cat4 people have to do that by themselves first.

[QUOTE=VictordeHolland;383879]There is a caveat with the 78M LL assignments, according to [URL]http://www.gpu72.com/reports/available/[/URL] , GPU72 has 7000+ TF assignments in that range. Primenet shows only 1800+ TF assignments, so many of the LL assignments are actually GPU72 TF (but reserved in the 'old' way).

Well that is good news!

@Mark Rose, luckily we don't run ECM on these exponents, as the header in your table would suggest ;).[/QUOTE]

I only copied the columns from what PrimeNet spat out on that page. :)

I had wondered about the assignments being handed out for P-1 being so high, but had not paid attention to the ranges for the different categories.

Perhaps I will shift my workers from DC to include a couple more P-1s.

We used to have a P-1 surplus did we not?

All I know is when I complete a GPU72 TF->74 assignment it gets handed out by PrimeNet for LL almost immediately.

I think we most desperately need TF fire-power. With the weather getting cooler here I plan to restart my 580. I think when a TF completes to 74 since there is such a small buffer it gets assigned to LL before it has a chance to be assigned for P-1. For instance, there is nothing available for LL P-1 right now. So it is LL-TF we need the most.

Can someone confirm this? I can put some 590s to work.

[QUOTE=blip;383908]Can someone confirm this? I can put some 590s to work.[/QUOTE]

All the evidence is pointing towards that. I'm tempted to pick up a couple more 580's this weekend. They're getting cheap now.

Cooler weather would make it easier for me to restart a 570, but only if I come up with a large enough PSU. An overclocked 580 + a a stock FX-8350 do fine on a 750 W, but it pulls just under 600 W. It wouldn't carry another 220 W. I'm not sure I could make it work, even by seriously underclocking both cards.

Besides, the 570 has some eroded PCIe power connectors, which concerns me somewhat.

Is that 600 W at the wall? What's the efficiency of your power supply?

If it's 85% efficient, you're only pulling 510 W off the supply side and have room, barely, if the 12 V rail configuration allows it.

I'm pulling 765 W at the wall from an 85% efficient 750 W power supply. I could still get another 100 W out of it before hitting the limit.

I would, however, be concerned about those power connectors.

Yes. The 600W is reading from a Kil-a-watt, and it is a Bronze rated supply. It has 4 x 18 Amp, 12 v rails.

I am surprised to see it still on the market. The NewEgg listing says "Fire Power" for the brand, but the unit shown still has "OCZ" markings. It still lists a 5 year warranty.

I am starting to wonder, again, about the 1 kW OCZ Gold which I had to stop using when its regulation went crazy. I guess I might try to make contact with the latest reincarnation of the company. Gotta look for a receipt, though.

On the 570's issues, I have considered trying to connect it by wire-wrapping and soldering the pins. That, or replace the connector altogether. I know that LaurV talked about tightening the female connectors, but that still makes me nervous after seeing blackened plastic on the cable ends.

Trying to squeak by with the 750 W supply and 2 GPUs would be an interesting experiment, but I have at least a vague memory of BSODs under those circumstances.

EDIT: It might work, though, if I throttled back on both cards. The 580 is rated at a 781 MHz factory OC (+10 MHz from stock), though I'm currently running it at 844 MHz. That adds about 20 W at the wall. The 570 came with an 844 MHz factory OC, but stock is 732. I'm not in a position ATM to check on what that does to the power draw.
