issues in drivers 93.71

marcosamerio · **Memory**: G.SKILL 8gb 9-9-9-27 @ 2T

i installed this drivers and run some games and benchmarks whitout any problems but when i tried to OC my videocard ( GEFORCE 6600 GT 500/900 )
its show this frecuencias whitout doing OC 500 / 1800

i do anyways the OC and get an improvement on final result BUT when i restart my computer the OC back to default every time

what can i do?

You can select a checkbox to remind your overclock

changed to the old CP and try to OC and i cant its have errors all the time

watch your OC it did funky stuff to my ram oced it to the max that the slider would allow

simply are wrongs this drivers at default show me 500 / 1800 velocities and apearss errors when i playing and i cant down the velociti of the memorie

this drivers are crap doesnt works well i back to 92.91

LOL! I have the same issue

My GPU RAM is stock at 2.5GHZ

what are people using to display the O'c options in the new drivers cuz it aint coolbits? I tried coolbits and it only shows ocing in the old cpl so what about the new cpl and post the link for the file too.

Yeah my ram is being shown at 2.21 GHZ at the moment lol.

NVIDIA must fix this problem with the velocities of the ram and re-release this drivers

stryfe2010 · 11-02-2006, 22:05 | posts: 100 | Location: OR

what u people fail to realize is that is the correct speed for your memory. Before it just showed the speed of one module and u times it by 2 now it's showing the actual speed of your ram with out having to times it by 2 which is what the vendors have been pestering nvidia to do for a long time.

what¿?

stryfe, yes on your gfx.. not the old series.

hmm yah so what insted if it saying 800Mhz it says 1600Mhz yah its showing the true speed no problems here

DDR = Double Data Rate

PBEBW: Please become educated before whining.

xankazo · 11-02-2006, 23:27 | posts: 2,630 | Location: Santo Domingo

my card's mem rated speed is 1GHz GDDR3 (which means 2 x 500MHz). If now it reads something like 2GHz, then something's wrong with nVidia coders and they should fix it.

marcosamerio · 11-02-2006, 23:33 | posts: 654

totally agree NVIDIA must fix that problem so much early is possyble

Thats 1ghz if you had DDR2!!!! Multiply it by another factor of 2 to get GDDR3 speeds. DDR2 has a doubled bus frequency, while DDR3 has a tripled bus frequency... and so forth. Therefore, take the actual clock rate and multiply it by 2 for each increase in bus frequency (2^1 for DDR2, 2^2 for DDR3). Therefore nvidia has fixed a problem that has been around since the start of GDDR3 which is why everyone thinks it is a bug, but it is not. Perhaps this should be stickied because I see A LOT of these posts coming.

why now we see this problems or issue and not before?

Kow · *Last edited by Kow; 11-03-2006 at 00:10.*

Because nobody brought up the problem before and they were probably marketed at the wrong speeds... which is why they didnt change the drivers and nobody questioned the effective speeds. If you dont know what the clock speed is you have to go under the assumption that the effective clock speed was calculated correctly.
I read up on how DDR, DDR2, DDR3 etc works and it is becoming clear that each incremental increase (1 to 2 to 3) is a 2x effective increase because the bus frequency is doubled per each increase. Perhaps back in the day when DDR2 was first released it would have been wise to stick with the actual DDR clock speed and just mention that "hey its DDR2 therefore the effective speed is doubled from DDR" or for DDR3 "hey its DDR3 so thats DDR clock speed * (2^2) for effective" . Now look what is happening, a lot of confusion.

Also for those saying "shouldnt DDR2 mean 2^2 for effective clock speed?" i say your right IF you are basing it off the actual clock speed. DDR by definition is Double Data Rate because it uses the rise and fall of the clock pulse whereas SDR did not (leading to DDR being 2x as effective as SDR, hence the name). As you can see this is something relatively simple that can get VERY confusing by marketing, which is what has happened. In fact, right now it looks like even nvidia might have messed up.

One more thing, GDDR follows the exact same thing as DDR. The reason its called GDDR is because its specially designed for graphics cards (very low latencies compared to system memory).

nVidia seems to be working around this whole mess by not even displaying the memory clock speeds in the products section of their website. Take a look at the 7950gx2 for instance, no mention on the speed of the memory, just the RAMDAC which is a Digital to Analog convertor used for the display out (CRT monitors need an analog signal).

Basically what we should be asking right now is, what is the actual clock speed of the memory on my video card? And from there determine what the effective speed is.

As already stated, the DDR value of the RAM is being shown, if you half the number you have now it should equal what it was before (stock)

If you want to overclock back to what you had before simple double the number of what you had before, althogh I advise benchmarking again with new drivers.

I Like the fact the cp is now showing the true speed, less math to figure out what the card is actually running at. so we had gotten used to doing the math and now nvidia fixed it so we don't have to and people think it's broken.

SLI is no longer an option for me. These drivers are so broken they don't even support nForce Pro chipsets. nVidia quality is getting more crappy with each driver and product release. My next system upgrade will be to ATI!

stryfe2010 · 11-03-2006, 04:59 | posts: 100 | Location: OR

hopefully this might clear some things up, on pg 18 of the release notes under nvidia issues-single gpu it states:Memory clocks displayed do not reflect DDR multiplier. Then underneath that it also states: The memory clocks themselves are running at the correct speed.

xankazo · 11-03-2006, 06:02 | posts: 2,630 | Location: Santo Domingo

so, it's just a BUG after all.

jgdiaz · **Memory**: DDR2 800 / 2gigs 4-4-4-16-2t

I have been playing with these and have had no issues on my 2 7950GX2's, but I did not see any performance increse at all on FEAR or HL2 but they seem to be ok and stable for me so far.
