Check out these two 1m runs I made the other night:
This is with my G.SKill FF's TCCD :

Now this is with my Kingston PC3500 BH5 :

Granted, a couple of secondary timings may be looser for the BH5's, but there's no way in hell that my spi time should be slower than with the TCCD. No OS tweaks for either run and each was made using the correct bioses....Anybody have any ideas????? :wth:

Dynamic idle cycle counter and the trc of 8 on the BH-5 is what I think is hustin the score most.

But by that much??

I know Dynamic idle cycle counter has made a good bit of differance in mine. Also was it run multiple times to compare? Maybe the tccd was just an unusually good run and the bh an unusually bad one. :confused:

I've made runs with and without dynamic idle on TCCD and tbh, it didn't make that large of a diffference. And yup, I did run multiple times to compare and the results seem consistent. I'll have to see if I have any more screenshots of the BH5 @ around that speed. Maybe it's just a crappy pair of BH-5's (luckily I've got 2x512 Mushkin Lvl2 Blk Pc3500's coming in the mail as we speak :woot: ) as it really wasn't an especially fast run for my pair of FF's ;) :

Actually, no... It's all in order. The reason for that is, that with 2x512MB 6-3-3-2.5-1T Bank Interleave kicks in and destroys a usual difference we used to see between 6-3-3-2.5 and 2x256MB 6-2-2-2.0-1T.
I noticed that a while ago, when DFI came out and was the only board with Bank Interleave option in BIOS. I might even have some screnies to show you... I'll try to dig them up.

I had a feeling that BI had something to do with the difference, but I didn't think it would have made THAT large of a difference :p:

yeah, yeah, yeah... true dat!
2 x 512mB of UTT/BH5 @ 2-2-2-5 around 265 would be nice! Interleaved of course...

ok, got it :) Spi 16M @ 3289Mhz DDR548 2x512MB TCCD vs 3300Mz DDR550 BH-5 2x256MB (CPU-Z reports incorect mem speed at multi x11 and div180).
There's slight difference in clocks, but that even plays in advantage to 2x512MB TCCD. Also, timmings can still be tightened on both. Anyway... You can see what impact Bank Interleave has ;)

trc has to be at 7 for amd ;)
Hmmm.....OK, so it looks like it was basically a combination of things that made my bh5 run that slow :rolleyes: I know it doesn't mean much, but here's the only screenshot I could find with trc@7:

Thx bachus for putting it in visual form for me :toast: And BTW, those are some nice clocks with that cpu :clap: I wish my chip wasn't such a dog :(
oh for clarifications
trc= tras + trp :)
since lowest "REAL" tras and trp atr 5 and 2 ya can do the math
its 7 :)
so your tccd vs bh-5 wiht trc=7 only on the tccd makes all the diff in the world.
could be as big as 1+ seconds in 1m alone ;)
I've seen the formula before, but obviously it slipped my mind as I was probably doing those runs @ around 3:30AM :p: Thnx for the reminder - I don't think I'll make that error again :toast:

yeah heres the oldest example of trc=8 casuing a mess this should have been 25s 1m "940pin chipset like 2yrs ago ;)"
I was pulling my hairout then found the bios I was on "this was before a64 tweaker" defualted trc=8 casuing the perfomace drop which was huge.
Never thought to check the RAM timings with cpu-z? ;) :p:

I have found the tref in the 1.95 scale to be slower on my board for both 256's and 512's of bh-5. Also the Read Preamble (for me) 5.5 is always faster for some reason, again with both size sticks. These links are for similar times with somewhat lower speeds. (except for the last one) http://www.xtremesystems.org/forums/showthread.php?p=904700#post904700 http://www.xtremesystems.org/forums/showthread.php?p=919634#post919634 http://www.xtremesystems.org/forums/showthread.php?p=1034454#post1034454 EDIT* The comment with the 1.95 scale is when I need to run with a 9/10. It may be faster if you can run 1:1.

Hmmm...never heard that before, but you'd know your hw, better than I do :p: . In regards to this run:
http://img326.imageshack.us/img326/2080/2536tf.jpg
I bet I could beat that time with my TCCD @ 1:1 as I've had a 25.5 run @ 3190 which I can't find the screen for ATM ;)
easy there, I thought you were wondering why your time with the bh-5 was not any quicker. As for beating that, you should be able to with that processor and running 1:1. I myself thought that for that speed the time may have been better. I was happy with it though as I usually used 512's and put these rams in just to see how they would run.

No offense intended - just trying to have a little fun ;) . Sorry I came across like that. As always, I appreciate any help given. :toast:
Not to worry, if I was as smart as...whatever, I would of ran my fastest time once, a long time ago. But, I'm not, so I'm getting ready to try some more. I've just started playing with DI and have never been able to run at such high speeds. I know there is something I can do differently to get better times. Thanks and GL with your Lvl2's.

unfortunately max my cpu can do on 26C water at under 1.64v
TCCD + bank interleave makes up for the looser timings compared to BH-5 check out rankings at http://i4memory.com/showthread.php?t=677

Only changed trc from 14 to 7, didn't expet such a difference

man so tempting to get those opteron 270s (for vB/mysql testing) but pretty much will go to waste for me and overkill heh
