WHY DOES GPU Z SAY MY MEMORY CLOCK IS ONLY 1566 MANUAL

Or the new GPU Shark display the effective DDR speed: For exemple, NVIDIA displays the effective memory speed of the GTX 480 as a DDR speed (1848MHz) instead of a QDR speed (3696MHz) (see specicifications HERE).Р”Р„nd what kind of speed is displayed in our GPU tools ?Р”Р„s we said, GPU-Z displays the real clock speed. IN practice, very often, the DDR speed is used in the specs of GDDR5 memory. Then for a GTX 480 (GDDR5) with stock memory speed we have: For example, the GDDR3 memory (on GTX 200 for example) is a DDR memory while the GDDR5 (on HD 5000 or GTX 400) is a QDR memory.Р”Р„nd the effective speed of a QDR memory is: Roughly said, there are 2 kinds of graphics memory currently in use: DDR (Double Data Rate) and QDR (Quad Data Rate or Quad-pumped). All other values you can read in other GPU tools or graphics cards reviews are the effective speed which depends on the type of memory (GDDR3, GDDR5) and people who have witten the specs, the reviews or the GPU tools СЂСџВвЂ° The real memory speed is the most important information. GPU-Z displays the real memory clock frequency or memory speed which is 950MHz (this is an overclocked memory since the stock speed of a GTX 480 is 924MHz). If we look at the image, we see that GPU-Z is used to monitoring the clocks and temperature. The guy who sent the image asked me why the memory clock of his GTX 480 is 950MHz instead of 1900Mhz. I think the system has a problem (look at the nice temperature spikes РІР‚вЂњ may come from a bug in GPU-Z, I donРІР‚в„ўt know) but donРІР‚в„ўt ask me whatРІР‚в„ўs kid of prob СЂСџВвЂ° Hummm tortured is not really appropriate if we look at the current intensity and GPU power: 27A and 29WРІР‚В¦ And the FPS: 34 FPS is too low for a GTX 480 even with MSAA enabled. Just dial in the max Power Limit and optionally Core Voltage, and let the algorithm do the work for you.I recently received this strange image of a GTX 480 tortured by FurMark.Р”Р‡urMark and an overclocked EVGA GTX 480 РІР‚вЂњ Temperature spikes

It is still possible to apply custom clock offsets to override Boost (this is essentially the overclocking that we're all used to), but in my experience, Boost does such a good job of pushing clocks near the limit, *without sacrificing stability*, that I honestly don't bother with manual GPU overclocking anymore. You also need to remember that the max clock Boost chooses using the default Power Limit and Core Voltage, will be lower than if you use Afterburner to increase those limiters. This may or not be the actual maximum clock your GPU is capable of - Boost errs on the conservative side, for obvious reasons. GPU Boost will clock the core to the maximum possible value *it determines to be safe*. The increments you use are up to you, I'd suggest 100MHz. But considering this is a mobile chip, you may not be able to increase those limits.Р”Р„s for memory, you do it the old-fashioned way: increase the clock by a certain amount, run a demanding game to ensure there are no visual artifacts, wash rinse and repeat until you see artifacts, then take the clock down a notch.

You can also increase the Core Voltage, which again will give more ability for higher boost. this seems like a reemergence of a previous bug where GDDR6 was effectively detected as GDDR5/X.Р”Р€) First, you need to get yourself a copy of MSI Afterburner, then you simply use it to push the GPU's Power Limit to the max which gives GPU boost more headroom to work with, which means it should now boost to higher clocks. Thus the TPU page is correct and GPU-Z is again wrong. On the other hand, memory should be showing 12000MHz since it's GDDR6 which is 8 bits/clock. But if there is additional thermal and/or power headroom, the GPU boost algorithm will allow the clock to be pushed even higher so that the card is effectively delivering its maximum possible performance within those constraints. The boost clock specified by NVIDIA or the manufacturer is the lowest maximum core clock that all cards are guaranteed to achieve. 1) Seems like a bug, paging Core clock is correct.
