I don't remember what blog/forum I was reading, but that was the gist of the idea - the better wafer/chips would go into the premium cards, the x80's and x90's...while the regular cards like x60's would get the just ok wafers/chips.

Do any of the forums say how you can read these values either from the hardware or via NVAPI? I would like to make SIV (http://rh-software.com/) report them. I have the NDA NVAPI and that does not seem to be able to do this.

It is more that they make a batch of chips. Lets say the GF110 which goes in the GTX560 to the GTX590 cards. The ones that test better get badged as higher end GPUs. Then the ones with bits that don't work correctly, fail to pass some validation tests, or if they just need more lower end parts get badged as lower end GPUs. It is a fairly common practice in the semiconductor world. So asking the chip who/what it is may not give you want you want.

Tried to go to 2300MHz from 2200MHz, I know it's 4400MHz/4600MHz, anyway the ram I think is as far as I can safely push the bandwidth as 4600MHz crashed the driver, thankfully I had 4400 saved and not 4600.

Fermis are know for not be very strong on memory controller. While overclocking memory and gaining not much(bcs bandwidth of 460 with 256-bit bus has proven being enough. It is not the case with 192-bit cards, btw, like those with 768 MB memory - they do suffer from narrow bus), you ruin overclocking abilities of GPU itself. Better overclock GPU than memory. 770 MHz is shy. Mine three run 810, while undervolted with 50 mV each. 850 MHz on default GPU voltage is common for all 460s I had and I have tested(over 15 pcs).

Hei, I had a monitor that looked a bit like that once.......
The infamous 'screwdriver' monitor. Oh, yeah.

Well I reduced the memory to 2000 and increased the gpu/shaders to 800/1600, I'm crunching wu's at about 16-18 minutes each, as to voltage Mine is at the stock 1000mV, temp thanks to the 1GB MSI GTX460 Cyclones big heatsink is 48C-49C...

I don't recall any discussion about how/where the numbers come from.

AFAIK, GPU-Z is the only s/w that has this feature. You might contact them??


I found this quote in an eVGA forum this morning (They were discussing GPU-Z..)


SirWaWa


"We've found the ways in which AMD and NVIDIA segregate their freshly-made GPU ASICs based on the electrical leakages the chips produce (to increase yield by allotting them in different SKUs and performance bins), and we've found ways in which ASIC quality can be quantified and displayed. Find this feature in the context menu of GPU-Z. We're working on implementing this feature on older AMD Radeon GPUs."



I don't know who SirWaWa is quoting or where he found that quote or even who SirWaWa is...but this seems to indicate the numbers are formulated from some other values on the ASIC chip (GPU).

Yeah I remember, I'm hoping Yer keeping Yer inner barbarian locked up a bit better these days Mark. ;) I just wish the card below didn't make the lines that are in the bottom picture.

Thank you for the info. I have tried asking such questions in the past and the only reply I ever get it's all NDA information. I will try asking my nVidia NDA contect how GPU-Z does it.

LOL...inner barbarian is still alive and kicking.....

Well it won't be until sometime Monday before the PC has 3 GTX460 gpus again, the two 460 cyclones are stuck in the Post Office, but then the place was closed today and yet were delivered to the Post Office, one needs a signature, must be too large for the normal locked PO Boxes.

Looking for best NVIDIA driver for two EVGA GTX 295, Windows 7 Pro, 64bit addressing, Socket 775, ddr2. I "upgraded" to the newest NVIDIA driver and my computer is slower crunching SETI! Went back to 290.53, but I can not remember what I had before. If this computer was dedicated to BOINC, would any OS beside Windows 7 make it run faster?

You could try the 275.50 Beta as that is what I ran on the GTX295 or 266.58, either will work.

I know there have been a few reports of GPU fan failures, but I have not seen one yet. I have had some cards fail outright. All fans locked on 100% here.

I had a fan fail on a GeForce 210 card ... no big loss since that is a pretty low-end GPU. You guys probably don't even consider that one as a viable option! :-)

I'm not sure how it happened, but the stuck pixels stopped being stuck for some reason on My Viewsonic VA1912wb LCD Monitor.

or, something like that... :)

Well I took the last 460 out of the case, as it went down to 405MHz overnight on 275.50, the GTX590 Classified is fairly stable, except for gpu usage which seems to go up and down at will, one moment one core will be at 1%, the next 41%, then 61%, then 78%, that's crazy, I'm doing 3 wu's per gpu core, the fan is maxed out at 95% and forget about the gpu core voltage, 1.000v is unattainable without the 267.85 WHQL driver, which nvidia withdrew and can't be found anywhere that I know of and I've looked too...

Hmm lets see ever since I uninstalled the (installed one at a time and uninstalled likewise) EVGA Precision 2.12 and the MSI Afterburner 2.2.0 Beta 15 I've had less problems, the fan now runs at 95% and My times for most files went from about 20 minutes to about 13, shorties are now about 3 minutes instead of maybe 6 minutes on the EVGA GTX590 Classified(03G-P3-1598-AR)...

I may try 296.10 and see how 296.10 does compared to 267.91...

Nice card, came with an EK acrylic/copper/Nickel(EN) block and EK 590 Backplate, Now I just need 4 more. :D This is going to be a long haul, but I don't have much else to do...

Oh and I found My Civ4 DVD, I installed the game and I'm now back in business...

296.10 has been problem free for me, Victor.

I power the monitor off when I'm not going to be here for more than a couple hours, so I haven't experienced Nvidia's 'sleep' problem with their latest driver/s.

Here I'm having monitor troubles, My 19" lcd monitor needed the power button pressed 3 times this morning just to get the monitor to work, so I've attached My spare 18" lcd monitor and duplicated the desktop on both at 1280x960, the 19" supports 1440x900 max and the 18" 1280x1024 max, needless to say the display isn't as crisp as usual...

Ok My monitor troubles will be over soon, I just got an LG 20" W2053TX LCD widescreen 1600x900 monitor, plus I replaced a multi-tool knife that I lost. The 20 inch LG monitor is replacing a cranky 19 inch Viewsonic monitor that's showing signs of failure...

Well the Viewsonic VA1912wb has just about bit the dust, I can press the power button and the monitor works for a couple seconds then goes dark, that LG Flatron 20" W2053TX LCD widescreen 1600x900 monitor was bought just in time, now I just have to wait until about April 4th 2012 before it's delivered...

The 18" Microtek monitor is now in charge.
