Hi.

I have never done any overclocking before and want to push my card a bit further. I was looking at this and was wondering if this requires additional parts that are not shipped with the cooler itself?
Also, as I have a golden sample 6800 GT, will it still be compatible with this cooling system?

How much overclocking potential will this give me and are there any other things that I should know?

This is the name:

Alphacool NexXxoS nVidia 6800/7800 Graphics Card Cooler

Thanks.

As long as you don't have this cap in your way, yes you can use the cooler.


How much you will gain depends on how much the card is pushed now.

Thats my card, only caps seem to be on the motherboard just above it.

Do you think that this would fit? = http://www.scan.co.uk/Products/Produ...728&source=bcl

hehe....the caps are on the other side. You'll have to pull the card to get a good look.

What is the make and model of this golden sample 6800 gt?

It is a Gainward Powerpack: GeForce 6800 GT 256MB DDR3 Ultra 2400 Golden Sample.

With the red cover theres only the two fans either side of a copper radiator(?)

Btw what is that black square thing in the picture?

If your talkin about the pic I posted, those are the memory chips. You might have to pull the cooler off to see if there is a cap in the way.....I will do some digging for you.

Looking up a review one can see that the caps are free and clear of the area. That cooler will work but your responses scare me. Have you even installed a waterkit before? One has to be carefull doing this, I don't care if water cooling is so called "Mainstream". The worst case will end up with a totaled system.

Hahah, don't worry - i won't be the one installing it, my mate puts the parts together for me (I have a phobia about screwing with the insides of computers).

Though I don't think my mate has any experience of installing a watercooler either.

So what would be a alternative and purhaps cheaper way?

For example: http://www.techniz.co.uk/modules.php...&id=321&page=4

Would this give the same cooling results?

OK, lets start from the beginning.....What are you try'n to accomplish?

Rather than having to buy new hardware and potentially a new motherboard to increase game performance I would have thought it would be better to get some decent cooling and overclock the card (as its meant to be overclocked)

Ignore the 500 mhz and 900 mhz (downloaded from a website). Actual reading on mine is 400 core clock speed, 1100 memory clock speed.

On full: Coreclock would potentially be 420hz and memory clock would be 1200mhz on full



Btw this software is bundled with the card.

Ok so you want to max out the card for a couple extra fps? And you want to spend $ to do it.....

Honestly you would be better to upgrade your card with that money. Hell even your system....

So the performance increase would be very insignificant? Damn.

Thanks for your help.

Yeah your ram is maxed out, the extra 100 hz OC will not be of any benefit.

Just adding to what Lokie said, your card is (the GT's) running pretty much as fast as the nv40 will go. (nv40 is the AGP GPU for Geforce 6800s). The AGP versions of the 6800nu, 6800gt and 6800ultras all use the same GPU.

When the chips are made, not all the transistors come out perfectly, so they're run through tests and rated. The top quality chips are given to the 6800ultras and 6800 GTs. The ones that aren't GT or Ultra grade are used to build plain-old 6800s, only one quad of pixel pipelines (one quad = four pixel pipelines. There are four quads in 6800s. GT's and Ultra's have all four quads enabled, so, 16 pixel pipelines. 6800's have 3 quads enabled, so 12 pipelines. But the other quad still exists, it just isn't used) are disabled to ensure there are no artifacts or stability issues and a vertex engine is also disabled, leaving 6800s with 5 Vertex engines (GTs and Ultras have 6).

These extra pipelines can be enabled, along with the extra vertex engine. Sometimes it will work, sometimes the pipelines will work without the vertex engine or vice-versa and sometimes, non will work.

GTs and Ultras are clocked quite a bit faster than Nus, too. My 6800nu came with a core of 350Mhz. With watercooling and a voltmod, I was able to get my card to 400Mhz, which is still slower than yours.
