undervolted and underclocked memory?

Wanted to chime in here just for the LULZ.

I have somewhere around 50 DC7100's D530 CMT's.

The D530's aren't worth a shit, but the DC7100's I have running (about have a 5830 or 5850 in them... on a 340W or 365W PSU.

And the damn things are overclocked to at least 950... and one amazing 5830 that sees 1010 on the core.

I just wanted to share.

What mining software did you use?

I got some in the fire sale too, kids were going mental at me to get them before they ran out, the main selling point of these things was Beats Audio and when they arrived the headphone socket only plays audio out of one ear!   WTF mono went out of fasion in the 70s!

Most things are like that nowadays. Quality has really went down the crapper comparing to yesteryear products. 

We have like 8 HP Laserjets over 10 years old, some 15, and we can still get toner for them and they work great!  So yeah, their older stuff was fantastic.  Then they decided to have a who can get the crappiest parts for the cheapest price contest with Acer and Dell

Dont get me started on printers!

I still respect HP.

Because my HP48sx calculator that I bought in 1990 still works and is still the king (imho).

The idiot who was IT manager before me and got fired got 4 off-lease HP-Compaq lay flat cases.  They're purposely designed with an L-shaped PSU so you "have to" get one from HP.  One failed and smoked and sparked up our conference room pretty good.  Another blew out in reception.  They wanted like $90 ea so for both, I put a standard ATX PSU outside the case and ran the cables in.  But HP thought of that!  The fan in the PSU is powered by a loopback cable from the PSU that hooks up to a 3-pin fan controller port on their rigged custom motherboard.  So now every time we turn them on, they beep angrily and you have to hit F1 to bypass the "no PSU fan" warning.  It is not disablable in the BIOS (even Dell's can do that!). Absolute bullshit.

So really, their enterprise products are giant boxes of scam and they're scam artists for selling those atrocities.  Out of all the PC's my other company has sold in the last 9.5 years, 1 has had a hardware failure.  Guess who we're buying the rest from.  I would not touch a personal or business product they make every again for any reason.

Oh and out of the 4, 3 had hardware failure since we got them 1.5 years ago.  I just swapped out a hard drive in another one with a 64GB Vertex 4 SSD it's really fast but thaaaaaaanks so much for that custom, one of a kind rail system for hard drive mounting.  That helped a lot!  Assholes.

Oh btw when shopping for printers, an ultra high end Xerox's TCO after 5 years was $31,000.  HP's somewhat mid level was $68,000.  Awesome.

yeah, i wasn't expecting 1GH out of the Tesla C2050, but 125MH is so not worth the effort it took to get the thing running.  Mainly I'm just looking for stuff to fark around with for the next month or two to take my mind off the stress of buying a condo and moving two apartments into it.

just for shits and giggles I ran my Quadro 4000s on bitminter today and they made the grand total of 48MH/s each LOL. I knew they were crap for mining but didn't know they were that bad!

When it comes to products made for the enterprise their support is reliable and spot on.

I don't know about consumer products, but HP support for enterprise systems is more than excellent. I've seen them sending taxis through half the country just to get a replacement part to the customer (ie. me) in the time alloted by the SLA.

firegl, quadro and tesla cards are the exact same cards as the consumer ones. They only have a couple register different and a different firmware. some have more memory or a difference clockspeed, but it's marginal at best. most of the boost is in driver optimization and software, not the actual hardware. the big point is they have better drivers for multigpu acceleration, for render farms.

The higher end cards tend to have better cooling than the consumer grade cards.

quadro cards specialize in massive 3D-related memory operations and quite a few cards ship with 4GB of RAM.  RAM usage is practically nothing for BTC mining.  They aren't even that great at Adobe Premiere rendering.  Like a 550ti beats a Quadro 4000 if I'm not mistaken and that's a liiiiittle dollar difference It's basically for Autocad Civil 3D and maybe Maya or something otherwise that's about it.

bleah. the C-series is crap. I had to basically strip the sucker down just to get it to fit in the case, macguyver up an 8pin block in addition to the regular 6-pin block power feed, actually got the thing to boot, and after farking around with the drivers and overclocking for 3 hours, i got it up to...128Mh/s.  Now, the S-Series, has 4GPUs...so it'll do a LOT better (a la the mining hardware comparison list), but we're not putting those in our high end workstations yet, so i'll have to wait to see one of those.

However, my workwife is also in HP PSG, and she may be able to get her hands on a few V7800's for me, which rock around 255Mh/s . I *will* have to expend a few buck on a new power supply, not to mention a board with several PCIe slots....but overall, shouldn't cost much to get a 2-3 card rig together to putz around with until BFL starts shipping Jalapenos..

oh well. time for a C2075!

You won't get much from teslas. Heck even my 2 Quadro 4000's don't do well for mining.

I have personally had no issues with HPs workstation level gear, I've had a xw8400, and currently still have a xw8600,Z400 and Z800 working away next to me now.

ya.. the 7990 is a pretty bad value for mining.

however if you wanted max performance and could ONLY run 1 card no matter what.. i guess then its OK.

good god. that thing is triple-wide?? HOly moly! Hrm. for what that's gonna cost, i could buy 3 of the XFX 7970.....(on sale at TigerDirect for $370 after rebate)....
