DFI LANParty UT ICFX3200-T2R/G - RD600 launched

[xlink]

Not meaning to knock RD600 but even my cheapo DS3 allows PCIe bus overclocking up to 150MHz (50%), 1T DC memory and several asynchronous memory settings.

Is there much benefit to PCIe overclocking? IIRC there is virtually no performance difference between 16x and 8x so why would overclocking the PCIe bus make much difference?

umm... didn't know intel chipsets could run RAM at 1T, care to enlighten me?

You may be correct about 965/975 using 2T cmd rate. I can't find anything definitive but I do recall that my old 865P chipset happily ran my 2x512MB DS Geil DDR500 at 1T in DC mode up to DDR550 (ram limit).

If RD600 does do 1T with dual-sided DDR2 in DC mode and 965/975 are limited to 2T, I suppose we might see the same benefits that 680i shows over 965/975 when using 1T cmd rate. Up to 3% better synthetic memory bandwidth scores and up to 1% better real world performance in the best case BMs. OTOH, I believe that RD600 can only do 1T with SS dimms which would limit you to 1GB wouldn't it?

I won't recommend 3.4 volts for a 24/7 use - only for short period benching.

But for me 2.71 Vdimm is no problem 24/7 with cold air ambient and two 120mm fans blowing to them:

Hope you dont mind losing that RAM, because it's only a matter of time..

bingo has been up to 420 on 2x1gb modules 3-3-3 1T.

How it performs there is anyones guess, but it is some speed.

430 3-4-3 1T now..
