Is this right? (GTX 460)

post #1 of 9
Thread Starter 
Hi guys I have overclocked my gigabyte gtx 460 (1gb) to these settings:

core voltage - 1012
core clock - 815
shader clock - 1630
memory clock - 2000
fan speed - 40

but when I ran gpuz it is indicated there that my memory is at 1000mhz. Is this normal? Can someone clarify it for me thanks

oh also if you could give me a better stable setting for the card it would be much appreciated

DDR stands for double data rate... so your effective clock is 2000 MHz.

How are you cooling the card? and what are your load temps? I found the optimal overclock on these cards to range between 850-950core depending on cooling. Memory could be bumped a bit more, however concentrate on the core clock first then the memory.

Good luck

EDIT: determine stability by playing games and no other way, GPU stress tests imho are only good for monitoring load temps.

Actually GDDR5 is QDR effectively, so his memory would be at 4000MHz.

Oh, and his core voltage is 1.012, his core clock is 815.

GPU-Z shows Actual Memory Clock Frequency, or 1000MHz

AB/Precision assumes you have DDR2/3 vram, which does two transfers per clock cycles, so it shows your 1000MHz (actual) as 2000MHz (effective) (wrongly, in this case).

Because you have DDR5, which does four transfers per clock cycle, your 1000MHz actual frequency = 4000MHz 'effective' memory frequency. This is the number you see quoted on newegg and such.

Is this a reference card? Should be able to push it a little farther. I have mine set to 900 on the core with 1.087 volts, and an aggressive fan profile. Folds 24/7

@ all

Thank you very much for clarifying these things to me. I'm quite new to the overclocking scene. The help was much appreciated.

@muanaim1
I'm using stock cooling for the gpu and 3 fans for the case. What is load temp sorry but if you're talking about idle temps it is about 40 and while playing games it is about 70 is that alright?

@mxthunder I'm quite afraid to adjust the voltage wouldn't it harm the system? Can you instruct me on pushing the setting further if it's ok with you thanks.
