Not particulaly hard maths though, just simple multiplication. Maths features in oveclocking the CPU too, you didn't seem to have any problems with that.

That number is never accurate, it's always rounded to a hundred. Just seems like CPUZ rounded up and your memory manufacturer rounded down. When calculating memory speed for DDR (and in fact DDR2 onwards as well), it's just frequency * 2 * 8. So your current memory bandwidth is 230.5 * 2 * 8...

Perhaps it wasn't obvious enough, but I wrote PC2 6400, note the 2. The second number wasn't important to the point I was making, so I merely chose the most common memory bandwidth for DDR2 RAM. For DDR2 400 RAM, it would be PC2 3200, however I have not seen any DDR2 RAM at less than PC2 5400...

Completely true, I said DDR not DDR2. DDR2 RAM wouldn't be rated as PC3200 anyway, it's much more likely to be PC2 6400 or some such.

What you could do is have 3 partitions on your Raptor. An ample amount for Windows, then a much smaller partition for the swap file (to prevent it from getting fragmented), and the the final partition to install app's from. With Windows at the beginning of the drive (and on a Raptor), it will...

Personally I'm a fan of linksys, however any router should be able to handle 5Mbps 24/7 without a problem, because it's actually pretty damn slow compared to LAN speeds, and 10/100/1000 switches rarely have problems. If he's had two bad units that's unlucky, all manufacturers make a bad unit...

If you are running your RAM at 200MHz then it is running at DDR400. With a 64 bit memory bus, that's 64 bits (8 bytes) per clock, which gives a total memory bandwidth of 3200 MB/s. Just because you have PC4300 RAM doesn't mean that it's operating at 4300 MB/s. That just means that the RAM can...

Well, when the RAM runs at a lower frequency, you can tighten the latencies.

Heh, alright then, good luck with your upgrade.

Well, faster memory means that more data can be fed into or out of the GPU and quicker, therefore the GPU will have fewer wasted cycles in waiting for the memory. The 1900 XTX TOXIC is a good card, and runs at 675/630 in 3D mode, but it's not too great at overclocking it would seem. However...

I'm quite concerned that your CPU fan only runs around 350rpm, is the fan speed temperature controlled by the motherboard? It may be spinning fast enough to cool your CPU, but any surrounding componants that rely on the CPU fans blow-off to be cooled might not be getting enough air moving over...

Basically, the 1950's use GDDR4 RAM, the 1900's use GDDR3 RAM. GDDR4 RAM can run at higher frequencies, so you get more memory bandwidth. There's some more on wikipedia: GDDR3 GDDR4

I've just added 4 Raptor X's to my system, and I didn't notice any noise increase at all, and no my system isn't loud, I've actually gone out of my way to make sure it's as quiet as possible and ... it's pretty damn quiet. Back to the OP's original question though, the two 74 GB raptors will...

Just an update for us UKers (I know there must be some on here somewhere), the average cost per kWh of electricity in the UK is approximately 8p. So the cost for running a PC in the UK 24/7 for a month would be around £17.28 (for a 300W PC).

I'm not really sure where they got the figure of 636 W, but with most systems (even high end ones), the power draw is likely to be closer to 1/4 - 1/2 of that, and therefore the price too. 0.300 kW * 720 h = 216 kWh 216 * 0.12 = $ 25.92 Even my file server with it's nine HDD's, and a...
