4x1 or 2x2

E8400/8500, ATI 4850, P5Q Pro/Deluxe. Not impressed w/V64 SP1, so XP now, maybe V64 later if/when impressed w/SP2 or later.

Should I expect better performance/reliability with 4x1 or 2x2? (Yes, 4x1 would be tossed w/OS upgrade, but then 2x2 might too--no guarantee that even same brand/model compatible 1+ years later.)

Been advised that OC performance likely best w/DIMMs that run at 1.8V stock--in practice meaning DDR2/800, not 1066. Yes? No?

lower colts means better/quality parts, more opportunity to tweak/OC

Because those sticks can further overclock to almost 1200 speeds. The DDR2 800 kit with the same timings can't get to 1000. And it has always been my experiencing that, with a few exceptions, RAM with tight timings volted upward doesn't perform much better then the same speed RAM with loose timings over volted.

Or you can buy these and not worry about the difference

Cshorte: volts?

Yes lower voltage parts ie RAM do mean a higher quality part with room for better tweaking.

Those are not on the QVL. Pricey too. I could upgrade the video or the HD for those $.

Anything G skill makes is reliable. The reviews for it speak to its quality.

You have to understand that if you do any tweaking to the RAM to get more speed or better timings you will have to up the voltage. That is why RAM running at 1.8v stock is generally better then the same specs RAM at a higher voltage, because it gives more room to play with them. All RAM degrades at about 2.4 volts. 2.2 seems to be good and stable for the most part. There is a difference between RAM sticks rated for higher speeds. A DDR2 800 kit with 5-5-5-15 timings can not oc to DDR2 1000 speeds with any timings. To get it past 900 you will have to increase the voltage on the RAM to do it. If you don't run programs that show a marketable difference in performance with tight timings or faster RAM (like games, which are largely unnaffected by RAM speeds), or if you don't need to get a fsb much higher then 1600 then DDR2 800 RAM will serve your needs the best. If you do then ten more dollars for a DDR2 1000 variant is worth it.

A Data is selling a quality kit for 74.99 at newegg with a free 2gb flash drive. It has a great number of reviews to assure you of its quality. Good luck with your purchase.

E3210: That's helpful, thanks.

Can I safely infer the that--for a reputable mfr-- the lower the stock voltage for the module, the more room to increase it?

The P5Q series boards have--I am told--a "wall" at 474-475 Mhz, which would mean that if I want to keep my RAM divider at 1:1 I pretty much have to use DDR 800.

That is not true... The P5q pro can except much higher level ram speeds then that. If that is the case then you should definitely get another board. I think the biostar t force for 89.99 is better in most ways anyway.

It may have a problem overclocking your cpu much higher... and if that is the case they were probably referring to the fsb and not the speeds (474 fsb multiplier is enough to get the 3.0ghz stock E8400 wolfdale to 4.2ghz oc'ed). Check back with your friend and figure out what he meant.

I meant the FSB. I don't know if it's true--I don't own the board (yet)--I've just seen it reported several times. And BIOSs get updated.

I'd be interested in your views on the Biostar board.
