Overclocking

[disillusioned]

what does T1 and T2 mean. I keep on people saying that "... can reach 2.2 ghz for T1" (did i say that right?? Anyhow, what does it mean???

They are memory command rates. 1T is better. You can only 2T if you use more than 2 DIMMs on an A64 board, so 2x1GB is better than 4x512MB in all cases.

All the single 1 gig sticks anywhere near the same price range as dual 512mb sticks can't hold their own in terms of latency. Where does that come in when overclocking?

Doesn't really matter for A64s. If you ramp up the FSB on the DDR past spec, you'll have to raise voltage and/or loosen timings anyway.

avoid T2 if you can. A better o/c will be eaten up (if not more) by switching from T1 to T2.

Here's a brief Sisoft Sandra Memory Bandwidth benchmark comparison from my notes in working up my overclock.
- 11X250 with RAM at 250MHz 2.5/3/3/7 with 1T command rate: about 7000/7000.
- Same settings, but with 2T command rate: about 6000/6000.

Unfortunately, I have to use 2T for complete stability.

Hope this helps!

I found this OCZ RAM that has timings of 2-3-2-5; it's $69.50 per 512 stick, which would make it $139 for one gig, or $278 for two gigs of the stuff.

I found this Patriot RAM that has timings of 2-3-2-5; it's $243.85 for 2 one gig sticks, or about $121.43 for one gig.


This is all assuming that you can't find 2x512 sets for the OCZ, which would undoubtedly take some of the edge off of the cost, but I think you see the point I'm trying to make.
