    Sorry for the late response, but it's been a sh1tstorm of work today to get this thing running. Got her folding a p8101 and letting her settle in. I appear to be having issues with that damaged chip. Vcore is 1.45 default where all other CPU's are 1.20v. I'm also missing a stick of ram in Bios on node1(damaged CPU). Aside from theses 2 issues, I like the performance. She appears to be pulling 350K ppd stock. I'll update more in the morning.

    PS: Tuesday looks like my 1st Million point day.:rockout:

    I hope you get the damaged chip problem sorted. Very nice build though, I am quite jealous.

    Good to hear from you El! I should have no problem with the chip return, just have to buy another at a decent price. You gonna crank up that SR-2 anytime this winter or are you already folding for HWC:eek:? :roll:

    EDIT: Grabbed another 6176SE on e-bay for $239.00!!! That's $50 cheaper than I paid for the damaged chip. When I receive the replacement, I will flash the board and begin the O/C sessions:rockout:!

    A million point day...wow. That's phenomenal! :respect:

    350k stock is amazing--but an extra 75k from OCing sounds pretty awesome too! :respect:
    Wow---$239 for a 12C CPU is great! And you're sure you can get a refund on the damaged one?
    Any idea when you're getting this one in?

    Yes, I should be able to get a refund. If the seller fights me, I will let Paypal/Bill Me Later settle it. I also have e-bay buyer's protection if I have to invoke it. I can afford to wait if necessary. New chip ships from Texas, so maybe by Friday?

    EDIT:Tracking via USPS says Friday delivery!

    Bogi's right, I'd never! I may tease them with my awesomeness a little, but there's only one bed I'll sleep in.

    Had to do a liitle arguing with the original seller, but he will fully refund the damaged chip. He was resistant until i sent him a pic of the damaged 6176SE. He even tried to blame my new Mobo and Ram:laugh:

    Because of the fubar'd chip and the vcore being @ 1.45v default, the rig is pulling 940W from the wall(at stock clocks). Normal Vcore is 1.18-1.20 for these chips. The chip is also running very hot @ 60C(48C for the other 2 chips). The VRM's for that chip were registering 95C surface temp until I put some fans on them. I expect the wattage to drop considerably when I swap with the replacement chip Friday Night.

    Wow...that's an enormous power increase! :eek:
    At least you're getting it sorted out :toast:

    I assume you're still folding on this chip until you get the new one in?

    I'm gonna work the piss out of it until i get the replacement. My next work unit should wrap up around 8:30 Friday night. I will then fold for 10 frames to get a baseline with the new chip, flash the bios and start the overclock. Might be up for most of the night Friday, but that's what weekends are for:rockout:. Temps are dropping into the 40's this weekend and the weather change will be nice!

    About what's the TPF on the CPUs stock?

    Weather change really will be nice...I just got back from class, and the room was like a sauna. Gaah. I can't wait for cooler days!

    The current TPF on the 6176 rig @ 2.3Ghz is 13:48 on P8101. The missing Ram dimm on node 1 is contaminating the TPF for sure. My 6180 rig @ 2.83Ghz does a TPF of 11:20.

    That's certainly a difference, but not really as much of one as I guess I would have expected. Are you missing a DIMM due to the damaged CPU, or did one of the sticks come bad?

    It's the CPU. I moved it to socket #2 and the missing dimm followed the CPU to node3.

    When the TPF drops, the PPD goes up exponentially. While there is only a 23K point difference per WU between the 2 machines, the 6176 rig does 1.043 WU's/day and the 6180 rig does 1.263 wu's/day.

    Opty 6176SE (1.043 x 323K) = 337K PPD
    Opty 6180SE (1.263 x 356K) = 449K PPD

    I'll get the 6176 rig up over 400K PPD for sure.

    Fastest Opteron 4P rig I know of is Grandpa @ [H] with Opty 6190's @ 3.0Ghz with a TPF of 10:33 and 507K ppd on p8101. Those are ES chips and I think he knows someone @ AMD. He also has 4 separate 4P rigs and a good retirement plan to fund these rigs.

    Oh, I'm aware of the exponential PPD. But a 100k+ PPD boost really is amazing! :toast:

    Wow...4 different 4P rigs...do they each have the quad-3GHz CPUs?

    And I assume that a quad-Xeon setup would still net higher PPD, albeit with a higher cost?

    So you're going to be at basically 850K+ PPD with these two systems...incredible! :respect:

    LOL, I have to laugh at this point or i may lose it. The new CPU just arrived, but there is some damage to the chip. About 15 of the tiny resistors on the back of the chip are missing:banghead:. I guess you get what you pay for and then not eve that on Ebay. I may have to return this one as well, but we will see.

    How the hell do you not notice that as a seller! :eek:

    I'm really sorry about your bad luck here...are you going to have to get a 3rd? :shadedshu

    I have to say that this is truly inspiring. I clicked on this thread because I am interested in the quad socket board Buck is running not because I used to fold a respectable 50,000 PPD. Perhaps after the new year I can get one of my cards going again...

    Going home to try it out now. If it works well, I'll keep it(fingers crossed). I'll post a pic with the HD camera when I get home.

    Swapped out the Chip and the replacement 6176SE works fine regardless of the missing resistors(or whatever they are). Vcore is 1.20 and temps are normal. Rig is only drawing 750W at the wall and TPF is same as before(13:50). Overclocking starts tonight!

    Woohoo! :toast:

    It's amazing that swapping out that CPU dropped the power usage by 160w! :eek:

    Are you going to complain at the seller and see if you can do anything, or just leave it as-is?
