I didn't realize that the GPU3 client supported the -advmethods flag but there is a nice 30% PPD boost for the advanced WU's.
The GTS450 is folding ~12,000 PPD with the Asus "top" factory Overclock. It's just behind the GTX460 in PPD (14,000) which is incredible because the card sucks little juice (single 6pin PCIE power adapter), is quiet, CHEAP AND runs cool.
There is no downside to running the GTS450's and they give monster PPD. I'll be cycling out my old, HOT, 98000GX2 (noisy, hot, expensive) that generated 10,000PPD for these GTS450's which are an across the board upgrade. Technology moves on.
Imagine if the top 100 TR folders spent $140 on a GTS450... Techreport would be generating an additional 8million PPW.

But still, it looks like the new ppd/watt/$ king since the GT 240 (which I have for the moment, for about ~3200 ppd ).
Ragnar Dan wrote:Looks like a pretty impressive deal. I'll have to look into this, with power usage being a key datum. I still have to figure out what's making my i7 run so hot, though, since it should be producing much better than it is and with less heat and seeming power use.

Thanks for listening.
JPinTO wrote:Mine runs too hot, though, and got worse when I moved it to a Lian Li PC-K7B case with putatively better airflow. So my problem is almost certainly the heatsink's connection to the heatspreader. I'm going to try remounting it once more at some point, and I'll use the thermal paste which came with my Noctua NH-C12P SE14 HSF (chosen for its low profile to fit in my previous case) just to remove that from the possible problems. If that doesn't work, I'll have to figure something else out. It has always run hot, from the initial boot to BIOS, and I'm wondering if the springs on the screws are keeping it from tightening enough to press as firmly against the heatspreader as it should. I'm running 1.15625 Vcore, which should not be giving me the temps I'm getting unless there's something else wrong.It's not just yours, the i7's run HOT. I've got a GTS450 in the same box as a i7 950 OC 4.0Ghz: The 950 cores run *HOT* at 85C. The GTS450 is running 56C. The 9800GX2 that was replaced used to run a 80-82C in the same box. The GTS450 is unbelievably cool running.
The power consumption on the GTS450 is minimal... how much can it consume with a single 6-pin PCIE power lead?
Ragnar Dan wrote:If Meadows's 100-110W is accurate, that's fairly much. Too bad you didn't have a Kill-A-Watt or similar to test the GTS 450 vs. your old 9800GX2.
which makes me think it may noticeably reduce the SMP2 client's performance, and therefore I'd probably put it on a machine which isn't doing anything on the CPU. If you have information which can help determine the truth of the matter, it will be helpful. I've got one machine I've been considering replacing, but I was going to make it run the SMP2 client. I might be able to run it on my Linux machine through Wine, but that may make it perform less well, though there is an overclocking utility I found which doesn't happen to work with my 9600GSO, but might work with this GPU. Decisions, decisions.Can I use my CPU to do calculations too?
For now, the GPU2 core uses the CPU a bit in addition to heavy use of the GPU. However, we hope to off load the calculation completely to the GPU in the future.

JPinTO wrote:Hm. Assuming you mean idle for "low", and low for "high", I've noticed that on high producing GPU WU's, such as the 353 pointers, my SMP client declines fairly significantly in performance, which is easy to detect on BIGADV WU's. When I last updated my video drivers I found the GPU's output declined, and doing practically anything made it give up cycles, which in Windows 7 was a new experience. I finally gave up and went back to the stock drivers (197.45) and things returned to normal. How much RAM are you running? Or do you do anything unusual to set process priorities? In XP I used to set the Fah_Core exe's priorities higher than the GPU client did, and that helped a lot.I run a GTX460 on a i7 920 and a GTS 450 on a i7 920 that run BIGADV. I set SMP priority to low, and GPU to high without allocating a dedicated core to GPU. GPU3 use of the CPU is 2-3% from what I've observed.
Four AMD Opteron 8356 (2.3GHz) processors, stepping B3 (WITHOUT TLB BUG) (totalling 16 cores)
Two Intel Xeon E5520 (2.26GHz) processors (Engineering Samples) (totalling 8 cores + HTT)

Ragnar Dan wrote:Someone else signed up on Newegg's email list: do me a favor and test if that card is still 10% off with the promo code listed in my last post. I went for it since it was $129 including shipping. I'm sure I'll be irked in a week or two about having wasted money by not waiting. But the thing I'm currently wondering about is if the expiration I thought I saw was real or if I saw it elsewhere. But mainly, I'd like to reduce my power usage on my main box, so a few bucks won't bother me... too much.
