Question about 2T/1T on 4gb DDR

[NamesDontMatter]

Okay so I just got in the second half of my new DDR setup today. For DDR I'm slightly underclocked at 190Mhz, but im running 1140Mhz @ HT clock. My Amd X2 3800 2.0 Ghz tops out at 2.8Ghz(stock volts).

I just purchased OCZ Platinum DDR PC-3200, both kits are the same make and stock settings are 2-3-2-5 @ 2T. I was able to squeeze 2-2-2-5 @ 1T out of just one kit of(2x1gb) at 2.85volts[remember this is DDR not DDR2] (the memory's maximum covered under warranty).

But heres my problem, when i added the second same make/model kit I could no longer run 2-2-2-5 1T on 2.85 Volts, meaning that my mobo would post the evga 29 code and basically won't post. But with 4gb I can safely run 2-2-2-5 @ 2T, do you guys think If I bumped my volts to maybe 3.05 I could run it at 1T? Is it worth the risk? My motherboard I will go all the way to 3.15 volts.

I know the actual performance benefit is 3-4% which would be quite nice.

Or Should I increase my Ram speed by 10mhz and decrease my processors overall clock speed, to allow me to run the memory at PC-3200 specs (200Mhz)?

also whats the best way to quickly bench the performance differences here?


Thanks guys!

1T on 4GB is probably close to impossible, especially if it's in 4 DIMMS...I now on Intel rigs we don't really get too much chance to do such, if you lower the memory speed even more you might, but really you crossed the line between more speed and more capacity, even at slower speeds you'll win with higher capacity imo. I notice a difference on my rig with 4GB in comparison to 2GB, in games, multitasking, multimedia processing and such...it makes a big difference and I had to relax my timings a tad bit at 4x1GB and drop the speed way down...now I have a 2x2GB kit of G.Skill at 5-5-5-15 CR2, 1000, 2.0v...amazing stuff, sure the timings and latencies won't even be in the top 100 for competitions, but even at slower speed having more memory at a slower speed beats having less memory at a higher speed that has to slough stuff off to the page file more often.

wont work with 4 sticks, but i think i have similar sets, iv noticed a slight decrease in max clocks with 4 sticks over 2, im currently running the sticks at the pc4000 spec ok though,
everest is a good program to quickly test ram to find whats best

I think I'm just gunna stick with my current setup. I just tried playing around with OCing and remembered how finky my motherboard is for overclocking. (Gotta reset the dumb pins). My Asus P4 socket 478 motherboard was more advanced than this evga sock 939, it reset bios to default with failed overclocks. So I think im just gunna stick with what I have, I played with it a little and the benefits are really marginal.

939 + 4 sticks of RAM = impossible. Regardless of memory capacity.

The memory controller in the 939 chip isn't as resiliant as the AM2 or AM2+ memory controller. It just can't handle running 4 sticks in 1T. I've never been able to do it with any of my 939 systems (and I've had about 8 or so) no matter what amount of memory is in each slot.

oh well thanks for responses guys.
