Graphics Card – ATI PowerColor HD3850
In the past, we’ve received reader feedback asking us why we hadn’t factored the graphics card into our overall cost estimate. This time, we therefore chose to include a real add-in graphics card in our overclocking system in order to be able to judge the energy consumption more objectively.
In order to make the results more comparable to one another we used our reference graphics card, an Nvidia Geforce 8800 GTX made by Foxconn, for all of our benchmarks. Since this card doesn’t really fit with the theme of our low-budget overclocking system both where price and power consumption are concerned, we chose a model from a more appropriate performance and price segment.
We installed the PowerColor HD3850 into our system. However, this configuration is only meant as an example, since we’re focusing on the performance of the CPU and the core components of the overclocking system and only need a graphics card for the power consumption tests. The performance benchmarks were not run using this card.
In the end, you’ll have to decide which graphics card you think will be the best fit the performance of our overclocking system.
| Component | Price |
|---|---|
| Processor | €49 |
| Motherboard | €88 |
| Memory | €54 |
| Cooler | €45 |
| PSU | €48 |
| Graphics Card | €180 |
| Total | €464 |
Here’s a look at the finished system as we use it for the power consumption measurements.

If I was tring to save a few pounds/Euros then what is wrong with a P31 based system board at around €50-60 and running the cpu it 2.66-3.00Ghz (333-357fsb), without having to spend another €45 on a cooler (Use the boxed Intel one).
Use the €75-85 you have saved to buy a better graphics card which will make more diffrence to gaming.
Here, victim victim victim... *starts sharpening P35-DS3L's claws*
Could any one recommend the rest of the core components to complete the system that whist sticking to a low/medium budget will not become so decrepid it will need chucking out at the next up grade. I am going from a P4 (and I was Delled) so I need everything except Keyboard/mouse and monitor. I.e a good quality case, Sata HD and optical drive.
It will not be a gaming machine but a home workhorse with some graphics work running XP2/Vist a ?Leopard (yeah I know). So the Power Colour gfx card is over kill and I am prejudiced against ATI(probably unjustly). I was thinking along the lines of a LIAN LI PC-7B plus II ATX case and a Seagate Barracuda 7200.10 500GB SATA II. Some Sata DVD/DW drive. (All Sata because of the ?Leopard bit I know I might not work ... yet.)
Any suggestions would be welcome.

On my ancient Athlon, Speedfan automatically switches from 107MHz FSB when CPU is 70%. The plug-in power meter I have shows 106W @ 107MHz (idle) and 131W @ 163MHz (idle). 1200% CPU uses more in both cases. This is on a A7N motherbaord that has a clock generator supported by SpeedFan.
I'm using a Arctic Cooling Freezer 7 Pro which is a bit cheaper than the one in the article and at 2.9GHz it still idles at 24 degrees C, and stays around 31 when under load (e.g. Prime95 or Crysis).
However, mine gets unstable at 3.0GHz - but I haven't tinkered with it so I don't know if it's the CPU or the memory - or I may just leave it as it is as it's running at 180% of the rated speed as it is!
One thing that caught me out... the Neo2 has an 8 pin 12V CPU power socket, and mine had no blanking plate (which you can see in some pictures of the board). When I plugged an 8 pin 12V lead into it into the 8 pin socket (I'm logical like that), it tripped the power supply. I double checked the manual on the Neo and the PSU and it appeared to be okay... but as soon as I swapped to the 4 pin power lead, it suddenly worked fine (thanks to the tech support at Scan for sorting me out)!
After reading this article, some other (about motherboards) and considering other not so cheap options, I tried my luck and changed my old PIV 2.8 based machine with this:
e2140 + gigabyte p31-ds3l + 1x kingmax ddr2 800MHz + radeon x1950gt, all together cost me about 240€, matched it with my old Hitatchi HDD and cheapo Codegen case with cheapo 400W ps.
Must say, this motherboard is great for overclocking (someone mentioned this chipset in earlier comment) cheap but stable with a lot of oc options.
New machine works great, from the start worked at 2,66GHz, with memory at 800 MHz,stock processor boxed fan without any need for adjustment. From 2,66 to 2.8 GHz, my enthusiasm was on pause a bit, failed to boot so I needed to adjust Vcore up a little from original setting (from 1,32500 V to 1,37500 V) and there I was in two steps at 2.8 and 3.0 GHz, reached FSB of 375, with memory running at 750MHz. Never tried to go any further.
With that final 3.0 GHz setting I run Prime for hour and a half, without any instability, and than I just give up Prime and continue my work as usual at 3.0 GHz with hours (better days) of gaming, multimedia and all that... no problems so far.
For me, it's great processor and perfect match for my GA-p31-ds3l motherboard.
