    So..., I set beta on my GTX 460's and got 9401's. Only problem is that they are on a A8N-SLI motherboard and it appears that the "slow" PCI-e or 3200+ processor is bottlenecking them. TPF is up to 4 minutes slower than my slower GTX 460 in a PII 805/880g system.
    Lesson learned: Don't build a F@H box on REALLY old hardware.:laugh: (I'm working on getting a P55/i5-750 to replace this)
    My GTX 560 Ti is doing TPF 18' 53" with an estimated credit of 36781 and PPD of 28048 on the 9401. These might put an even greater load on the CPU than previous core_17 WU's.

    Check the run. The pre 300 are slower....

    Aah, a (282,0,5) has a TPF of 29'9", a (529,0,4) has a TPF of 27'39". Identical cards.

    From my experience with GPU folding, even core_17, the CPU has little to do with the TPF and slow PCI is not a big slow down either. My slow i7-920 (3 Ghz or there about) does just fine with it's 7950 (90k PPD on 8900). Not far away from my 7970's (8x and 4x I think) which with a 4,075 Ghz i7 does both around 100k PPD. OK they have a more modest OC. Please don't ask for actual clocks. I'm still in Turkey.

    :laugh: You seem to have forgotten that Nvidia GPU's now put a load on the CPU with core_17 while AMD GPU's do not. I sat at that system yesterday and watched the 2 processes for the 2 slots each push the CPU to 99%. The CPU (A64 3200+) on that system is running at 100% and it's only job is to run those GPU's for F@H. I don't think that the PCI-e 1.x @x8 is having much affect on them, but I do think the slow CPU is. That system had been running the 8018 WU's so this was not an issue with the core_15 WU's. If I can not get a replacement for it, I'll eventually put my 4400+ in there, which should help, I hope.
    It was sweet to see my GTX 560 Ti drop a WU worth 36,751 points.:laugh:

    I tried to spool up some of my cpus to crunch with and my ppd on the gpu went into the toilet. It seems from my experience that the 5 series were alot easier on the cpu but the 6 series had to have at least 2 cores or ppd plummeted. I could crunch and fold with the 4 and 5 series cards but not the 6. Thanks MS again for the info on the 9401s. All my gpus were lower ppd today and they are all on less than 300.

    Hey Team

    Just in case anyone missed it, we're doing a crunching challenge and would welcome any assistance you guys can bring to it.... details are in my sig :)

    *Note- keep an eye on the challenge thread for details on an upcoming game giveaway to kick off the challenge- which will be open to all active TPU crunchers AND folders! :toast:

    On a side note- I should have my 7970 back up and folding for the Team by the end of the month :cool:

    I say we take spot #30 tonight:rockout:, then focus on adding any CPU's that we can for the WCG Team Challenge. It's only a week and we will back to clawing towards spot #29. Awesome PPD lately guy's. You are rocking it!

    My AMDs takes 1 full thread from time to time regardless if it is a 4 or 6 core Intel. I think that there is a limitation in (Intel) CPU usage to one core/thread.

    We are doing good. I seems to have lost my two 7970s some time yesterday. Internet seems to be good (got my WGC units from same rig in 10 hous ago) but folding WUs are still waitning to upload. I can't imaging that the two GPUs crashed and the CPU is still up. I have no possibility to check on them so we might be 200K PPD down for some time.

    Update: The system got 2 6900's and the CPU load averages 50%. So, the 9401's put more of a load on the CPU than do the 6900's.

    yes they do.
    btw I got a 1049,0,0 on the 570 and its pulling 43k. Its been sitting on that ppd for over 3 hours. Seems like 9401 ppd is all over the place.

    Interesting finding: I switched my CPU over to WCG and initially gave it 80% which turned out to be 6 threads. This is my 2600K with a 7770 and GTX 560 Ti. both GPU's were doing ~24k on the 6900's. The CPU was not showing 100% load, so I bumped WCG to 88% which resulted in 7 threads. Here's the interesting part. The PPD for the 7770 went down. Not the Ti. Down to the upper 19K's ATM. So, even though the Nvidia GPU's use more CPU, it seems that the little CPU that the Radeon's use is very important.

    Just a heads up. The 750ti consumes ~60w and performs about like a 660 in F@H i was reading.

    Back up with sli 680s! :clap::clap::clap:. Then found out after turning off sli that they both are putting out way less ppd than what i was getting with 1 card. Cmon BBB, how do I get these to play nice?

    Remember to leave two cores free. I have no problem with two 7970s in same rig. They both each produce what other people does with one in the rig.

    Looks like MS got his machines back to work! Getting the other 680 spooled up kinda funny why it takes a couple days for them to get up to speed. 42k on a 9401. :cry:. Other one 92k. Both on 4.4ghz 2600k.

    Yes one rig locked inside my workshop decided to start folding on the two 7970s. Still have a X280 doing nothing in a working rig.

    And they don't seem to be adjusting the points. Weird.
