New GPU Units?

[Overvoltage]

Thanks for the prompt reply, great info I'll have to reapply my Tim. Anyone have a recommendation for thermal pads? I'd like to replace mine in the 480.

Seems to be a common thing the video deal I looked at one of the links MtM posted about it. I'm not running into it. I watch you-tube vids in full screen and I just fired up a 12 Gig rip of Blade Runner along side it to see if I had any problems. No issues running two monitors and that video in full screen while folding on the CPU and GPU.

Do you run SMP on that machine? Any feedback on your FSB? You could have a little bit of a bottleneck somewhere and a good boost to that with a lower multiplier on the CPU may get around it, if it's applicable to your set-up.

A year or more ago I had the lag on the desktop problem running Vista, made the PC nearly unusable if I was folding but a few tweaks to force Aero to stay on got me around it. That was on a 8800Gts. MtM makes it sound like they will go in and intentionally lower the utilization of the GPU for these units, they did it in the past from what I remember when the a14 core was new ( I think it was a14 something like that.. I don't pay much attention to it )
I don't like it when certain "features" are disabled to protect people from their own mistakes or refusal to accept their equipment can't run the super-duper settings. I see it a lot in games, max settings, max draw distances, loading speeds have their bar lowered to cater to the crowd who refuse to do it for them selves, leaving those with higher capability equipment lamenting their loss of eye-candy.

No I did not say they will force the wu's to go slower ( that's impossible ).

They can either keep these on advmethods the whole time, or they can add fah_gpu_idle support on the core running these unit's. Or they can do nothing. Irc it was fahcore_15, not 14, but I didn't even start on my morning coffee right now.

Watching 720p video software decoded and upscaled to 1080p using ffdshow and rendered in Media Player Classic Home Cinema with the EVR Custom Pres renderer. I did not try with TMT5 using hardware decoding, but a lot of the videos I watch don't support hardware decoding (10 bit anime). Your tests sound like they all would have been using hardware decoding.

I am running SMP, FSB is set to 233 (dft 200). I don't think the CPU or northbridge is the bottleneck here, I think it's the GPU. I might try a different renderer, I wonder if haali's would work better.

Running dual screens is a good way to lessen lag issues as well btw, WDM acts as a buffer between screen updates ( don't ask how exactly, idk ). With both my screens on my nvidia I have terrible lag though as well, both screens on my ati I have lag ( less then with both on nvidia ), when I run one screen from my ati and one from my nvidia I have no issues at all. Only thing of importance is that I need to make sure my screens run at their max refresh rate. Default for the ATI goes down to 60hz which will cause headaches.

Off topic: foldingforum.org is down Edit: back up again, had dns issues.

These units are great for PPD. 12.8k PPD on a stock GTX 460.

When I have my 460s in SLI though, the Windows UI is completely unusable. Everything is slow and runs like crap.

Glad I have a new GTX 570 on the way.

Did a quick test on a 10 Bit anime in addition to regular old 8 bit files I have laying around ( yes it's really 10 Bit ), played it through Windows Media Player Classic Home Cinema and was using FFD show for Audio and video and I also ran Haali media splitter. I'm seeing the stutter everyone is talking about, but only if I want to grab a window and drag it around and or resizing it. Actually watching the video while normal net browsing and playing a simple game like Osmos or Terraria isn't proving difficult nore shuddering to any degree. It's an issue that has popped up on units in the past, but I'm not seeing a quick tweak for getting rid of it.

Trying the same in single monitor resulted in the same thing, loss of playability and shuddering of the video only when changing the size of a window or moving it.

I'm running dual monitors, one for gaming and the other to watch HFM and various other resource monitors. ATM I'm running an SMP and a GPU client along with Bitorrent and Kingdoms of Amalur game, and almost never see a single stutter. The occasional stutter used to happen simply from the SMP in the past so assume it's that. The only thing I'm noticing is on this game while folding I used to get about 80 or so frames, and now average 65-70. Every setting maxed and one 570 card. This is why I haven't been in a huge hurry to put everything back in the haf-932 case so I can squeeze the other card in hehe. These excellero xtreme coolers are the size of a cinderblock and difficult to use 2 in a case without sacrificing something. Even watercooling wasn't all that much better temp-wise, not enough to waste the time and money anyway.

Check if setting cpu usage to a lower value helps, in V6 use the slider or setting under 'change advanced settings' with the console client. With V7, add 'cpu-usage' with a value of let's say 90 to your 'additional slot options' ( need to have advanced or expert settings turned on ).

Well, for most of the episode it's fine. It's just occasionally that it messed up. I was actually able to watch about 15 minutes before I started having issue.

BTW, I was talking about possibly using Haali's renderer, not Haali Media Splitter (though I am using that). You can change the renderer in the output options in MPC-HC.

I was thinking about trying that... I may today...

The settings works for all my gpu cores but those don't include fermi or opencl ati.

OK, thanks.

Haali renderer seems to fix my video lag problem in MPC-HC.

[_MtM_]

Seems the fermi's are less capable of being adjusted this way since they use less cpu resources ( and this setting affects the cpu cycle, not the gpu utilization directly ). Might not work satisfactory.

Has anyone noticed it to be worth while to overclock their GPU with these new cores. I know that past cores did not have any major increase when overclocking.

Personally I'm going to go to a non-OC setup for these units and bite the bullet on up to a 14 second addition to my frame times per % to keep power draw down and fan noise an a sane level. I don't feel it's worth the extra resources and can live with units taking about 20 minutes longer to complete.

I've run 8031 and 8033 units. While both units work the GPU quite hard, the 8033 pull a tiny bit more power in relation to the 8031 and I had to drop 25Mhz off my overclock to keep the temps reasonable and the units stable. Comparing these two units to the previous batch I'm seeing up too 27% more power draw over my VRM for the GPU, and a ton more heat in general, someone with poor case flow or a fixed fan profile is going to burn their card up on these units.

As a side note I just finished a 6099 SMP unit. No idea what kind of unit it is or how big the model is, but that thing took me 38 hours to complete.

Solid 48C @ 870MHz. it will probably max out to 50C.

I'll let you know if i see a major jump in PPD or TPF.

48C? What are you cooling your card with?

Liquid

Its a GTX 480 FTW

[MattSharkey]

Well Take it for what you want, here's my Overclock, Stock, and Underclock stats. The underclock is actually similar to the reference clock for this GPU.

Overclock:---870MHz, 2:18 TPF, 24061 PPD, 49C
Stock:------ 752MHZ, 2:38 TPF, 20949 PPD, 45C
Underclock:--700MHZ, 2:50 TPF, 19474 PPD, 42C

Ambient Temp is 24C

Going From Underclock to Overclock:
24.29% increase in Clock
18.83% decrease in Time
23.55% increase in Points
38.89% increase in Power Consumption (based on Delta T)

[jmossman]

Think I might try and see what it takes to get a stable 900 clock on my 570. It's got a great 5 pipe/3 fan cooler that tops out at 60C-62C at 850 core clock. Makes me wanna see what else it can do.

[MattSharkey]

I could never get 900 stable on my 480 (basically the same card) but you can certainly try. good luck!
