[Update 25/11] 2GB of DDR2 for overclocking what to buy

[zbomb5610]

Great point Hutch, my 8000HZ's (4-4-4-5) had extremlty tight sub-timings by default and needed to be loosened substantially for any decent clocking. With that said they were by far the fastest modules at 1000Mhz I ever used! Zbomb have you verified what IC's your F2-8000PHU2-2GBHZ's are running? It would be great to know because their known to come with a few different chips? Also where did you get them and how long ago? Thanks for your help!

i haven't verified, i figure the only way to do that is to remove the heat spreaders, which i don't feel too comfortable doing. I received them last monday, so it has been less than a week since i got them. They had the black pcb. Purchased from newegg.

I know someone else that bought them from newegg about a month ago, and they are running 4-4-4-12 1000 @ 2.1v which is great, but i can't manage that unless i do 2.2v.

tWTR 13-14
tRRD 5-8
tRD_WR 9-10

Also try Ras to Cas 5 and if all that doesn't work try 5-5-5-15 timings to see if that gets you higher clocks. If it doesn't it means you're probably chipset limited.

It seems that the DS3 is ignoring most of the settings in the SPD of the ram. I get pretty much the same sub-timings with my crap sticks (they're either elpida or powerchip.)

I messed with a few things, i changed those settings in memset, then i figured i would play with overclocking the memory, but the only way to do that is to change the memory multiplier in bios and then overclock in windows, but when i changed the multiplier to 2.5, it cold booted and reset my settings, and i was trying to boot at 400fsb with ddr2 1000, so then i changed the memory multiplier to 3 and did about 350 fsb and it booted. I then tried to mess with overclocking, but cpuz didn't read my memory timings, either did memset, seemed like the memory wasn't being recognized.

I did change the fsb to 370 so x3 would be ddr2 1110 and ran super pi with that, a lot slower than usual also, like 22 sec, i normally do 16 sec.

I really just feel like playing with this memory is a waste, i probably got some ic's that aren't d9gmh which sucks. I think i will just wait for the ballistix pc8000 to come in.
