Point of View GTX 570 TGT Ultra Charged review -
Overclocking & Tweaking the graphics card
As most of you know, with most videocards you can apply a simple series of tricks to boost the overall performance a little. You can do this at two levels, namely tweaking by enabling registry or BIOS hacks, or very simply to tamper with Image Quality. And then there is overclocking, which will give you the best possible results by far.
What do we need?
One of the best tools for overclocking NVIDIA and ATI videocards is our own AfterBurner which will work with 90% of the graphics cards out there. We can really recommend it, download here.
Where should we go?
Overclocking: By increasing the frequency of the videocard's memory and GPU, we can make the videocard increase its calculation clock cycles per second. It sounds hard, but it really can be done in less than a few minutes. I always tend to recommend to novice users and beginners, to not increase the frequency any higher than 5% on the core and memory clock. Example: If your card runs at 600 MHz (which is pretty common these days) then I suggest that you don't increase the frequency any higher than 30 to 50 MHz.
More advanced users push the frequency often way higher. Usually when your 3D graphics start to show artifacts such as white dots ("snow"), you should back down 10-15 MHz and leave it at that. Usually when you are overclocking too hard, it'll start to show artifacts, empty polygons or it will even freeze. Carefully find that limit and then back down at least 20 MHz from the moment you notice an artifact. Look carefully and observe well. I really wouldn't know why you need to overclock today's tested card anyway, but we'll still show it.
All in all... do it at your own risk.
|Core Clock: 732MHz||Core Clock: 810MHz||Core Clock: 860MHz|
|Shader Clock: 1464MHz||Shader Clock:1620MHz||Shader Clock: 1720Hz|
|Memory Clock: 3800MHz||Memory Clock:3960MHz||Memory Clock: 4500 MHz|
Now we left the fan RPM control at default, increasing it might get slightly better results yet also noise levels, and we want to prevent that from happening. We reached a very decent overclock on a pre-overclocked product, guaranteeing better results. Voltage tweaking is not yet an option. Our stable end result was 860 MHz on the core and 4500 MHz on the memory. The temps did not change very much, DBA levels remain very silent at roughly 41 DBa (measured from 75 CM distance).
Above you can observe results done wwith Call of Duty: Modern Warfare 2, maxed out image quality settings as before with 4xAA 16xAF
Above you can observe Battlefield Bad Company 2, maxed out image quality settings with 8xAA 16xAF

Today a review on the ProTAB 2 XXL 10" tablet from Point of View from their Mobi range. With a price of only 169,- EUR the specs are decent enough alright. Interesting enough for graphics, the ProTab2XXL also comes with an additional MALI-400 3D graphics chip. Now we never heard of it before tbh, and very little can found about it on the web. But we can certainly measure it's performance and it does allow for FullHD playback. The Mali graphics chip even allows to drive a mini HDMI v1.4 port.
Point of View GTX 570 TGT Ultra Charged review
Today's offering is of course a GTX 570, we nicked it out of the Eindhoven warehouse from the good people at Point of View. See, their TGT team is chunking out several new SKUs based on the GTX 570. Today we'll have a peek at their Ultra Charged model. The UC version is a guaranteed stable factory overclocked product that is overclocked towards a pretty impressive value. See, the default core clock frequency of the GTX 570 is 732 MHz, the TC version is clocked at a blistering 810 MHz, which is a pretty decent overclock. Memory wise spot an increased clock frequency on that 1.2 GB GDDR5 memory as well, taken from 3800 towards 3960 MHz.
Point of View Ion 330 motherboard review
We test an ION 330 based motherboard - ION is a relatively low cost GPU assisted solution that will allow this industry on very short notice to have netbooks with full HD playback quality, in multi-channel HD audio. A solution that even supports CUDA and therefore some simple PhysX functionality, but since it's CUDA compatible, it'll also allow encoding and acceleration of popular video content. A platform that supports Gigabit Ethernet, dual-link DVI (high resolution monitors), acceleration in Photoshop CS4 and heck... you can even play a couple of games or make a mini HTPC out of it, it's just really interesting as the product might be little, yet offers a lot.
GeForce 9600 GSO 384 MB review | Point of View
NVIDIA replaced the GeForce 8800 GS with the GeForce 9600 GSO. The 9600 GSO is still based on the same G92 core with 96 stream processors that the 8800 GS has, but NVIDIA gave card makers a bit more freedom in their designs in terms of own PCB design to and determine their own clocks. This 'old' card will still have 384 MB of GDDR3 memory over a weird 192-bit memory interface. Cards like these will sell for less than 99 Euro, and considering the performance you get returned for that, you'll love it.
