Core vs Memory Clock

Last response: in Overclocking

Hey guys! So I've been overclocking for a while but I haven't really brought into mind, "which is better" High Core clock or High Memory clock? I assume it depends on your system which I will post specs but I'd like to know a little more about the two in terms of performance. -Thanks


Gigabyte H55M-UD2H mobo
i3 530 at 3.4ghz
Mushkin Enhanced DDR3 4GB (2GBx2) 1333mhz
Sapphire HD 5770 Vapour-X at 930 Core / 1350 Memory (Stocks are 860 Core / 1200 Memory)
1600x900 res always
Thermaltake 500 watt psu / 43amps combined on 12V rail

I just love your Computer Jobs forum.Thanks for posting it. it have something that someone comeback again….there is a lot of useful information a person can get discussion science article and a good users,which contribute in the forum MCITP from here…I must say,well done.A good forum with great


Anyway, core clock improves the rendering speed, while memory clock improves memory bandwidth (I guess). So overclocking both would be ideal, but modern graphics cards are limited by the GPU, not the memory bandwidth, so I guess overclocking the core should yield better results.

Isn't memory bandwidth only really important when you're using multiple monitors and high resolution? Since I'm only at 1600x900res should I go for the highest core clock possible?

It's important for high resolutions and anti-aliasing. I think high memory overclock doesn't affect core overclockability so I think you can just overclock both.

From my experiences they don't affect each other in terms of overclockability, they both have their own limits. Personally, memory clocks have been more beneficial to me than core clocks, but together its just awesomeness.

You could just go for trial and error and overclock just the core and then just the memory and see which yields better. But again OC'ing both is generally beneficial all around.

How is memory overclocking more beneficial than cpu overclocking? Is there an example of a program or game that benefits from higher ram speed and not higher cpu speed?

we are talking about the core and memory clock on a video card dude^^ not RAM and cpu

Ah,lol. I guess the answer was too obvious for me to think he was saying gpu memory.

Amazing!I also wish him good luck to defend his gold medal. I like to share it with all my friends and hope they will also encourage him.

When you decide to buy medicines from online pharmacies, it is important to purchase only from licensed pharmacies in your state as well as take time to look for adequate company information.

I've similar problem, i.e. posting on similar threads,

I'm sitting here at work trying to figure out what I want to try next as far as getting everything stabilized in my system. I'm going to drop back down to 3.0 instead of 3.1. However, there are several core frequencies combined with the multiplier that can get that speed. What I'm trying to figure out is, besides its effect on memory and the HTT, what is the advantage of having a high core clock vs. a high multiplier to acheive the same speed?

I tried some site to figure it out solution but still waiting for their reply Software Wiki, Free software reviews.

Thanks for your time.

wtf is it just me or is there stuff here that makes no sense.

These are nice gadgets. highcore clock does it well for me. billing jobs
