Topic: So, my guy at HP Personal Systems... (Read 4942 times)

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)....

ugh, yeah, i will agree with ya about hitachi drives. i've never had any luck with hitachi, and i do deep digging before i buy something now to make sure it doesn't have Hitachi inside...

Well, market share would seem to support us in the server space. the DL380G7 was the best-selling 2U/2socket box in the world for 2yrs straight. the DL380G8 looks well poised to keep that going... 

As someone who was a hp/compaq server customer/user/admin long before i joined HP, I can honestly say that I had very few issues with the servers. a few add-on card failures, a drive failure here and there, but overall, the ProLiant rackmount family as a whole was pretty solid, and from what I've played with here for the last 2 years, it's still pretty great stuff.

We're anonymous here, so i've got nothing to lose or prove by spewing marketing bullshit and "company line" rhetoric....yeah, a lot of our PSG (now PPS) stuff sucks, particularly our attempts to get into the handheld and tablet markets (although the Slate2 is a pretty good win7 tablet device..i have one, it's a fun toy...could use a little more OOMPH in the CPU, and a bit more ram, but it's a pretty cool tablet), but printers and servers and storage, we're still kicking ass, and we're gaining share year over year in networking...Cisco is still the big bear to beat in that space.

Not gonna lie, this year's been tough. we reduced our workforce by 30,000 heads worldwide a few months ago, offered early retirement to a bunch more last month, and there'll probably be another round of cuts before the end of the month (our year end).   But it's been a tough year for almost everybody in the tech space. We're not the only ones taking a beating out there.

and no need to apologize for sticking to Cisco servers/blades. If they're working for you, and you're happy, then good on ya! :-) I certainly won't slander them by sayign their stuff sucks, cuz it doesn't.  They make industry standard servers, we make industry standard servers.  apples-to-apples, the hardware's pretty close to being the same. it's the management software and functionality stack that really differentiates.  For example, our Gen8 servers, blades and rackmount, are 3 seconds to video on a remote management connection, which is a huge improvement over the previous iteration. let's you see POST a lot sooner and react a lot faster to any error states.

Anyway, almost time to call it a day, gonna go home and install this Tesla card, run GUIMiner for a little bit just to get an idea of the performance, and then play Torchlight2 on it for laughs. Then back to my 6770. :-)

and sorry, csshih, i gotta give the Tesla back in a couple weeks LOL

Ohhhhhh so he was already inside cuz you work there  Didn't think of that possibility, lol.

The lowest failure rate I've seen on a HP laptop is 24% over 3 years (realistically I'd say 75% but that's what squaretrade said) so congrats, you fell within the odds just barely, lol.  I however, at my shop, have a stack of 5 different dv6000-9000 models that are totalled.  Also, my brother's mother in law got 1 from the store and the keyboard didn't work so she returned it and within 1 week, the 2nd one's screen failed.  HP uses the worst parts for all their systems.  I saw a $900 elitebook come in and it had a Hitachi hard drive.  You cannot escape from their non-existent part quality standards at any price level!

Oh and as for Meg, do the paraphrased words "Let's stop making desktops and kill the entire division of our company that makes them....aww fuck it, keep making them" ring a bell?
She was right the first time.  I told my server vendors at my other job I'm not even touching an HP server until they assured me about 10 times that their server products aren't like their desktops (or printers) at all and they're actually respectable and don't fail.  We're still getting cisco ones, sorry I am under the impression that HP is incapable of building anything good after seeing their printers, laptops, and desktops so not ruining their company's reputation by making them would be a very good idea.

I run a repair company and after seeing so many bad parts and unnecessary failures of parts and bad product designs and bad software, I would not use an HP computer if it was free.

when you're done playing with that card I would love to buy that from you

I work at HP too...so he just walked by my cube and handed it to me.

Believe me, I'm well aware of the issues in Personal Systems Group, and our revolving-door CEO position. Don't even get me started on the TouchPad. I bought a bunch during the internal "fire sale", and flipped em for a 300% profit by hacking them into Android tablets.

I will say, however, that my last two laptops have been HP "entertainment" PC's, and i have had no issues. 

Meg's a moron? hrm. haven't seen that yet, but time will tell.  Bankruptcy? You must have better sources than i do...

Hmmm I don't get it...at my work, if anyone comes in trying to sell us HP equipment, we throw furniture at them until they leave.  How did yours make it in the door? lol.

Are you not aware of their bullshit prices, awful warranties, awful support, beyond awful hardware with massive failure rates, the fact that they're dead last in customer satisfaction and dead last in failure rates in 2009-2011 for laptops, their printers' TCOs are the highest in the industry, their server parts have about a 1000% markup, their software is written by morons and is bulky, non-working crap for any product they've ever released, 5 of their last 7 CEOs got arrested, their tablet was the worst disaster in recent tech history, their current CEO is a moron, and they're headed toward bankruptcy?

Check out powercolor Devil 13 for mining.

Wonder how the S2070 got such a high Mhash rating?  Must be a major architectural difference between the C-series and S-series teslas?

Should I even bother having him get me a Quadro6000? or just see if he has any ATI V7800's in the store room?

*edit* yeah, just found out. S-series has 4GPUs, C-series has 1. That'd do it. so, basically, i'dget about 1/4 of the Mhash...like 125....bah.

ah well. if he has some V7800's lying around, those are probably EOL soon and he can write em off/dump em.

Yeah, the Nvidia cards just suck for mining.  Probably great for Folding@Home projects though.

*booooourns*

Well that kinda blows.  Still gonna toss it in anyway, just for shits'n'giggles.  First time I've had my hands on a $2000+ video card...got a bunch of ATI FirePro and FireGL's (V7800, V7750x2), but those are old.

I wouldn't waste your time, you'll likely get under 100 MH.

...jsut dropped me off a Tesla C2050 to play with...

can't wait to get home and install it in my mining PC
