Good call there Mindweaver!
Congrats on becoming a Mod
Yep Buck, it's my cruncher sig, 1 285 and 1 260, plus my i7 xeon of course. Now I understand how this works a bit better. When it first starts out it actually uses 8 cpu wus and 4 gpu wus, but it changes down to 4 -4 after not long. If it runs out of gpu wus, then it goes back to 8 cpu wus, probably what was confusing me. I just need a 970 is all to do what I wanted....
You'll notice that the GPU's will outproduce the CPU's handily, so don't worry about the cpu cores being tied up with the GPU wu's!
Yes, by far. It might actually be better to try and assign more wus to my gpus, and just use the cpu to feed them. I bet my output would be higher.
Hey guys just wanted to let you know I order a 7770 the other day. It should be here tomorrow. I plain to put it in one of my 1055T's. I've had some issue with that x6 1055T.. It had a HD failure.. So, I order a new drive and pick that gf up too.
Watch the timeframes for completed GPU workunits and avg them out. There is a "sweet spot" as well as a "point of diminishing returns" with multiple WU's. Good Luck!
Your PhII X6 should make for a very impressive crunching rig
Our master cruncher Mindweaver is a mod! Congrats and you deserve nothing less sir!
Well, like an idiot I forgot to plug the Ethernet cable in for my Ethernet bridge, so the HD7770s spent about 8 hours with no work (amazingly, it burns through the entire buffer in less than two hours). Everything is fixed now
I broke down and decided to upgrade the GTX 580's...
Hmm - what did I buy
Maybe something from the Red team?
Let's just say something a lot more powerful than the current AMD cards I have!
pics or it didn't happen
On my end I have two rigs getting a refresh (12c/18t additional when I'm done). Still considering some more gpu power but can't afford the top end atm
Will be getting them Friday. Pics will follow shortly after
I have a new cruncher to throw in the Grid
A Dell Inspiron desktop with a C2Q Q6600
I'll probably set it up some time tomorrow morning
Ah, the venerable Q6600. About 5 years ago that was the CPU to have for F@H. You could run 2x SMP clients at a time for 5k+ PPD. It was like Witchcraft!
Anybody got experience running a (separate) PSU just for GPUs?
I've run out of PCI-e cables on the HX1000 but have spare PCI-e slots on the SR2 for another GPU. I could do the pin-hack thing to power another GPU on the SR2. But I am little worried about setting a PSU to constant ON with a GPU.
That was the CPU I used in my first custom-built computer. Old, but still a very decent chip IMO
Can you use molex-PCIe adapters? I'd say that 1000w should be enough for 3 HD7950s and the two Xeons. Or I know Buck had experience splicing two PSUs together--you could check with him
Hmm, might need to go check the specs, not sure what power is available over molex. Hadn't thought of it, yet so simple!
Use one of these. Put one off the first card and the second off the second card so all 3 cards divide the power between the 2 originals.
That's as long as you have enough power for all three cards.
Awesome. Well think this is the best solution so far. Gonna go find the rails diagram for this PSU and order a couple of those. Big thanks
EDIT: Yeah, should have enough Juice. Currently loaded at around 50% with 2 GPU so as long as I check the rail schematics and divide the power correctly there's still some headroom left.
They do make adapters that allow you to put two PSU's on the same system. I know Lian Li had one with the PC-A10B case I reviewed here: that case has two slots for power supplies, and 1500W PSU's weren't possible back then.
Ah, looks like the one BUCK suggested too. Was the most likely route I would be going down with the second PSU hanging out the side of the case. But think I'll probably try F150's splitter to keep the single PSU.
My case has space for 2 PSU too but I took up that space with a H100 cooler. Never thought I'd ever say I'm struggling for space inside an Elysium
I regret selling my Q6600 as with that multiplier it could do 3GHz on G41 chipsets, but I have a Xeon X3210 which is like a 2.13GHz Q6600. I'm tempted to find a Q6700 on eBay but I think I'm probably better off letting this old stuff quit working and parting with the chips.
Considering letting go of my Phenom X3 8550 for a reasonable price if anyone here is interested, as I don't really want to find any more AM2+ boards for it.
Well, for reasons I don't understand the C2Q isn't powering up right now. I should be able to keep the C2Q chip and exchange the rest of the setup for something similar on Saturday. We'll see
I've tried different RAM, a different CPU, and a different PSU, so I think it must be that the motherboard is bad.
