Question about a BIOS setting.

How does the PCIe frequency affect the video card performance and other system devices? Should it be changed and when??

Personnaly, I've found no benefit with changing it. If anything, it's made my system LESS stable as I pushed the frequency higher. If someone has negotiated a higher frequency (with benefit to performance) then I'd like to hear about it also.

Hey how about some advice for watercooling the 2900 XT? I am thinking about taking the plunge. What's the best set up? I like how the EK blocks look--but do they hold up?

I bought the EK block so I can offer some insight. I bought it from jab-tech which was the cheapest place. I havent installed it yet so I cant comment on performance, but I can tell you that the version I bought CANNOT have the barbs facing different directions (up/down). They are both orientated DOWN, which means flow from your chip, which is above the gfx card, is very difficult to route into the gfx card. I could not install the barbs in the other direction more than one thread into the block, meaning there is no seal. Also, if you were somehow able to screw them in, it would only allow maybe 1/8" for water to flow into/out of the block. The highest flow setting is with them both facing downwards, and it is difficult if not impossible to install them any other way. I have the Non-crossfire version, so the crossfire edition might fix this particular issue.

The Koolance blocks have been working great for me, you can orient the barbs however you want. Temps have been awesome, idle at 30 and 34, load at 38 and 43. Not sure if the other blocks perform better, if they do... amazing.

My GPUs are on their own loop, so dont expect those temps if your CPU is also in the loop.

As for price, I paid $90 a block.

Convience factor? Koolance ftw, they are based about 30 minutes from my house, so it was very easy to go get some parts that I forgot to order.

That sucks being able to walk into a Water Coolers paradise

Glad to hear that the Koolance work well--are you using barbed or slip fit connectors?

Think its called a compression fitting, which i HATE WITH ALL MY BEING! I literally got a blister from putting one together. I dont recommend using those.... at all.

I have a straight up fitting on the top card, a solid 3 card slot fitting between the cards and a 90 degree rotating fitting on the bottom. The liquid goes directly from the pump into the bottom fitting, then up and out to the rad.
