I have no doubts in your system, it sounds very cool 8)
But there is a problem and you know engineers always try to fix problems. And what you already found out clearly shows the following:
Either you Mobo is "flawed" and has issues supplying a "good/clean" enough 12V supply to the card for the worst case/furmark,
or, Powercolor doesn't really test/cherry pick the GPUs for their G!G series, which I doubt anyhow, and the 1.0V for the GPU is a little bit optimistic-> too low for some units, maybe in combination with certain mainboards?

But obviously, you should get the card replaced to be sure it's not simply a "bad" unit...
Honestly, your results don't encourage me to rush and buy the card for now - waiting for your result :wink:

Hey W1zzard,

if you can change voltages, how low can you go in idle and load modes (stock clock settings)?
And what are the resulting consumption values?

In case anyone is interested, I just installed one of these in my computer. It fits with lots of room to spare in an Antec Solo, and idles at the mid to high 30s in my case, which has the Tri-Cool exhaust fan set to low, and two Nexus 92 mm intake fans spinning at ~1050 rpm.
I haven't used it to game yet, and don't think I'll run anything very intense, but I'll post some temperature numbers when I get them.

lowest voltage i could set before the card crashes is around 0.775 V

0.80 V = 13.6 W
0.85 V = 14.0 W
0.90 V = 14.3 W
0.95 V = 14.7 W

I noticed the review at Techpowerup, and the power consumption figures are great!
http://www.techpowerup.com/reviews/Powe ... _Go_Green/
Just one drawback IMO, the VRM chips have no heatsinks, and you'd have to take the GPU heatsink off to install some.

Temps are no issue, i measured 65°C max temps on the vr components.
That's during Furmark, in normal use the're much cooler.

Just to add a quick update, after about 1 hour of gaming (Starcraft 2 Beta, high graphics settings) the card's temp was 57 C

Wow. Nice to see you posting here W1zzard, fantastic software and reviews over the years.

Didn't realize how fast these 5750's were until tonight...and the power draw is very nice :D

This is really nice card and worth the premium (at least to me). The heatsink looks pretty high though, would this card fit in say, Silverstone SG05? I tried to fit in a Sapphire 5750 with a Thermalright HR-03 Rev. A cooler, but the heatpipes are simply too high (by a few mm).. Would love to get this card, but only if it fits. :)

Could you also try to lower the load voltage, just to see how close to the limit we're there?

@W1zzard: I'd ask you if your power concumption figures are measured at the wall socket?

I'd love to know accurate power numbers for the non-Green version of the fanless Powercolor 5750 card.

Hi, this one looks like a good performance/power/noise (tbc for noise?) compromise. But will it fit in a Silverstone SG06? If not, would a reference 5750 with a Musashi or Accelero S1+fans fit in such a small case?

A new Review in german from ht4u:
http://ht4u.net/reviews/2010/powercolor_radeon_hd5750_go_green/#inhalt
HT4U results:
2D idle 15.2W
3D avg. 57.7W
3D furmark 66.8W

Techpowerup results:
2D idle 14W
3D avg. 45W
3D furmark 62W

interesting...

not sure if this is the right place to post this but, for 5750's has anyone got the iCooler IV version from HIS? from the TPU review it looks pretty good in terms of noise AND temperature (not sure what went wrong with the 5870 version lol)

Well, Powercolor lists the dimensions (here) as 205mmx131mmx38mm. I'm not sure, but just from looking at pictures of the case I think if those numbers are right it'll fit fine.

I have assembled a new PC recently and I can confirm that the Go!Green fits nicely inside a SG05.

I believe my system specs are basically beyond reprove.

Antec P-183 (4x120mm case fans)
Seasonic X-650 gold
Asus P5Q pro turbo
Intel C2D E8400 3GHz
Mushkin Blackline 4GB DDR2-6400

Believe me I have done my homework and stability tested the Lord out of every component in this box. The issue with the Go green 5750 isn't heat, when I slap a fan on it I can keep the core below 45C, and it still can't furmark, or even old games like Portal, without crashing my whole system. It's certainly not a question in my mind whether my power supply is up to it.

Which leaves the card itself, and indeed, when I lower the card from 700/1150 (stock) to 600/1000 it's stable. Unfortunately this isn't acceptable for me because it's an expensive, premium part and I don't see any reason to satisfy myself with anything less than stock performance.

There are also other glitches that plague me on this card like a glitchy second monitor, and when I go to 'test' any new clock settings (even if it's just the stock settings) in CCC I am greeted by a vertical orange/rose colored striped screen. I have to hit esc to get back to my system.

So in summary, this card is about as useful to me as bat guano. I'm returning it tomorrow, unless you want to pay me full price for it.


Here are some comments from Newegg:


Poster on Newegg wrote:

At stock settings, I experienced frequent lockups (grey/striped screen of death) during regular 3D gaming (even older games like Portal) and in Furmark. I had to actually underclock the card from factory settings to attain stability, but never achieved perfect reliability. I found I could also improve stability by tying a huge 120mm fan to it and running at full 12V, thus negating the whole point of this PREMIUM, passively-cooled part.

Unfortunately, I will have to return (my first return from Newegg) this card and consider purchasing a reference design 5750 or 5770 and an aftermarket cooling solution.

Other Thoughts: My relevant system specs are as follows:
Intel C2D E8400 3.0 GHz
Mushkin Blackline PC2-6400 4GB
ASUS P5Q Pro Turbo
Antec P-183 / Seasonic X-650 Gold PSU
3x 120mm case fans (noctua/nexus)

**Case ambient temperatures reported by mobo at 26C. My case is cool enough to run my CPU completely passively with the Noctua heatsink. Prime95 Stable (24 hrs+), Memtest86 stable (12 hours+).


Are these problems that at least two users have run into likely just bad cards, or likely some other kind of problem?

If you run into such a problem what do you do to determine if it is a bad card or there is some other more subtle problem. How do you diagnose it? Or is the simplest solution just to RMA the card and try a different model?

It's probably just a bad GPU. Unfortunately the 40nm process those chips are made on is full of problems. The ones that work properly are superior to all else on the market but a few slip through the cracks that are right on the borderline.

Quote:
According to Digitimes, Taiwan Semiconductor (TSMC) can't get its manufacturing process to yield more than 70 per cent, which is causing huge problems for the production of next-generation graphics processors and FPGA (field-programmable gate array) chips.

TSMC is the foundary of choice for GPU vendors AMD and Nvidia as well as FPGA chip supplier Altera.


Quote:

TSMC HAS FINALLY come to terms with its 40nm ordeal. In a transcript published by EETimes, Shang-Yi Chiang, TSMC’s R&D boss, laid out six bullet points to explain the situation the company is coming from, what steps it’s taking to make amends and where it's going.

The 40nm yield issues were blamed on the company’s previous lack of experience with the new, smaller node. Without going into too many specifics, Chiang explained the delay in achieving a viable yield was due to it using 193nm shrink immersion on the wafers, which resulted in a high defect rate, and also its low-K process that would damage the dies when converted into a package. TSMC is looking at extreme ultraviolet and e-beam direct write as alternatives to shrink immersion depending, of course, on cost.

Having its clients breathing down its neck couldn’t have been easy. TSMC immediately started developing its 3rd generation manufacturing process on the node. Currently, output for 40nm wafers is 80,000 wafers per quarter, as only Fab 12 is manufacturing these. However, the company vowed it will be able to double that by year’s end, that is, 160,000 wafers per quarter, once Fab 14 is up and running.

...
...

Considering TSMC’s major clients are the likes of AMD, Nvidia, Broadcom and Qualcomm. not to mention Intel, it seems that it's taking fairly important measures to reassure its clientele about its manufacturing. Of course we should expect a reaction from Global Foundries soon, as it are developing competing processes in their own house.

So, if you’re a GPU buff, late 2010 or very early 2011 would be a good estimate for a new generation of GPUs. That, or smartphones. We'll have to wait and see. >µ


It all just depends on when you want to buy a video card. If you are wanting to buy something between now and spring of next year you might as well buy a 5750 and test it with your favorite programs before the return period is up.

I wouldn't hesitate to buy one but like any electronics product there will be duds.

If I got a dud I'd return it and get another one just like it. More of them work than don't.

Besides any other video card you buy is likely made with the chips from TSMC. It doesn't matter what you pick you can't avoid them right now.

One question about the powercolor passive versions (SCS3 and Green):

Are the cards exactly the same, but with different operating voltages, or do they have different designs?

Because I'm thinking that it could possible that going with the SCS3 (cheaper) and undervolting it, the consumption results could be similar to those of the Green. And so, a second question arises... Is the SCS3 undervoltable?

I suggest you reread the entire thread every bit of what you just asked is thoroughly discussed here.

Short version is No, Yes, No, No if I counted the questions right.

Thawing, flowers, etcetera.

We are really gumming up a 5750 thread talking about general timelinesfor the video card industry.

Some time between now and infinity new video cards will be released I picked Spring because its after Christmas and I don't generally recommend buying things at Christmas pricing and there is no guarantee that the fall 2010 video cards will be any better than the spring 2010 cards or that they will be available in quantity before spring 2011.

To add to the fun newer CPUs will have GPU on die so it all changes and that is supposed to happen in 2011 as well.

But really this is very very off topic for a 5750 Go Green thread.

Thank you :)

I thought that my question(s) was about not the exact same thing... I've read in the thread about the comparison with reference design, but I couldn't read about the exact SCS3 model, which by looking at the pictures looks like exactly the same as the Go Green.

And by the W1zzard results, I've seen that the Go Green is undervoltable, so I was wondering about the SCS3...

Sorry if I misread something, I'm from Spain and my English is somehow limited...

Thank you again, I will keep checking the thread for new information :)

on the topic of 5750 cards GIGABYTE GV-R575SL-1GI Silent-Cell is now available in the US (and presumably elsewhere).

Keep in mind both the Gigabyte Silent Cell 5750/5770 and Sapphire Ultimate 5670 have heat sinks that extend over the top of the card meaning smaller cases might not be compatible.

Another drawback to the 5750 silentcell is that it has one VGA connector instead of a display port connector that is common on more expensive 5750 cards. As in 5750 Silent-Cell has DVI, HDMI, VGA but the Powercolor 5750 has 2 DVI, 1 HDMI, 1 DisplayPort. But if you can put up with the loss of port(s) and the oversized heatsink it's cheaper.

prices shipped to my home

Sapphire 5670 ultimate (fanless) $125
Powercolor 5670 Go Green (fanless) $135

GIGABYTE 5750 Silent-Cell (fanless) $135
Powercolor 5750 SCS3 (fanless) $155
Powercolor 5750 Go Green (fanless) $195 (note this one does not require 6 pin power connector as it uses less power than other 5750 cards)

GIGABYTE 5770 Silent-Cell (fanless) $165 (this one unlike the 5750 has DisplayPort and does not have VGA).

It makes it a tough sell to go fanless and not spring the extra couple of bucks to step up from the 5670 to the 5750 assuming you can afford to house a 2 or 3 slot card and aren't limited by height issues.

It also makes the GoGreen cards a tough sell on price at the 5750 level knowing how many other 5750/5770 cards are cheaper.

Just found a head to head review between the 5750 go green and the 5750 silent cell at http://www.hardwareheaven.com/reviews/1 ... cking.html short version is if you have some ram sinks laying around the Silent Cell is a winner. The Go Green has ram sinks preinstalled but is more expensive. And of course there is the size and video connectors to think of.
