HK police i tried a lot of ram with the gigabyte , the best is BH5 but the problem is that you have tu give them more than 3V to have stability , and boot with 225-230 FSB in bios.
I also tried some CH5 (A-data-corsair) they worked fine, and very stable , if i remember , with Adata 256 i could reach 235 2 2 2 5 Vddr with stock 2,85vddr (+0,2 bios).
After Vio=vddr i was able to bench superpi at about 265 2/2/2/5.
With CH5 corsair 512mo 1.2 (LLPT) i could do the same, i think with 256mo sticks LLPT it will be a lot better.
I tried Samsung TCCC , working good also but slow timings of course.
I tried MDT sticks (made in germany, very cheap sticks= 75 euros/512mo sticks) ,with them i could have 240 Prime stable 2,5/3/2/5 with very speed A64tweak settings : i could have 32sec superpi@2509mhz.
Kingston valueram chips kingston 256mo sticks works good too.
If i have to choose an available pair of DDR for benches , i ll choose the Corsair LLPT 1.2 sticks, less none doubt.
Nforce3 loves them.
