Eva is 100% right. In my case, and this is 2x256 LA TCCD bank interleaving makes it more stable not less. As far as performance goes I don't see any difference.

of course :)

Man I love posts like these, makes me so happy venice is coming out. I'm going to be able to move to an A64 setup for dirt cheap.

LOL. You can buy my Winchester when I sell it in a month or so. :fact:

Hurray! Cheap part for poor people (me)!

On topic, i havent really pushed my memory all that far (around 260mhz cas 1.5 or 2) but i left bank interleaving on with my bh5 memory. Everything went fine, up to there anyway.
Cas 2.5 wont run no matter what though, i tried getting 285 1:1 with cas 2.5 but my memory doesnt seem to wanna run at cas2.5, maybe thats whats causing it? Ill have to try that when i get home

BH5 has big problems running anything but cas 1.5 and 2.

Hey guys, here's another tip -

I just got in another DFI Ultra-D, since the other one was having issues. I put the new one together and left the chipset cooler / TIM in tact. I was having random freezes at 300 FSB. Last night I yanked the board, removed the terrible yellow putty on the chipset and replaced it with a nice coating of as5. I can now prime and super pi32m at 300 FSB x 9 with only 1.53 volts. Very happy with the new DFI Ultra-D, the last one and the RMA had some issues. The first one was the worst - random reboots, problems with USB etc. I had done this with the first one too, but sometimes a bad board is just a bad board.

Bottom line - removed the yellow putty on the chipset and replace it with some quality AS5 (or comperable TIM).

wow i still have stock what ever paste under my DFI NF4 SLI-D's chipset heatsink heh

That TIM material it comes with is like gum! That is 1 of the first things I do when installing a new system, yank the chipset cooler and replace the stock goop with some AS5 (in the case of NF4 chipset or Intel chipset) or Ceramique with the NF3 type chips.

It does make a difference with my Old Geil UltraX

However in the bios when I disable it, save changes and go back it will show that it's enabled again. I think part of my issue and the reason why stability is so spotty is because I will disable it run a bunch of tests to confirm stability then go back into the bios to make other changes at which point the board is re-enabling it on it's own - then I have problems so I back it down to still have issues (which is why this is so frustrating). Till now I wasn't paying attention to the setting when I went back into the bios. However I think this is the setting that I've been looking for!

If anyone can confirm that they see it auto enabling upon re-entering the bios or having stability issues that are resolved once it's disabled - please let me know. Thanks!!

I hit 290HTT no dividers but i did notice when disabling Bank interleaving system was more stable and you are able to increase the FSB more.
But who knows maybe different memorys have different yeilds. I dont know which type of TCCD i have all i know is that its pretty old. If any1 knows how to tell pls let me know.

thanks

Same here but I've never seen it really affect stability like this! EVA 2000, what kind of cooling are u using?

With certain types of memories disabling bank interleave does heavily improve overclockability. :fact: For example, OCZ Platinum RevII 2-2-2-5 benefit heavily. And yes, certain mobo vendors have found this out and exploited it to achieve better O/C numbers than their competitors, especially for the purpose of web reviews. One particular set of dimms that I've tried picked up around 35-40MHz at the same timings by just turning off the interleave.

yeah BH-5 is on memory that excels with interleave disabled heh

dnottis, i'm using MCW6002 + MCP650+MCP600 in series with Thermochill 120.3 with 3x 120x38mm panaflo 103cfm fans to cool cpu only and 2x60x25mm fans over ram modules :)

I think I need to go water - this chip did 2.8 @ 1.6 on water forthe previous owner - for some reason I cannot prime any higher than 302mhz with this chip and it's only at 1.53v. I think my limitation now is cooling.

Hey, but wasn't it that if turning bank interleaving off, you got a noticeable performance hit?

Nah, it's slight actually. Actually I can prime at 1.53v (9x300) with it disabled or 1.58v (9x300) with it enabled. Its currently at 8hr, 45mins prime stable at 9 x 300 with it enabled.

I noticed about 200-300mb/s difference in Sandra with it disabled...but it seems to be much easier on my chip's mem controller - I gained ~20MHz. Need to do more testing.

I get 7800 without it and 7916 with it enabled. Benchmarks are up a bit too. Since it's only .08v to enable it and run stable - what the hell I'm doing it :)

14 hours prime stable so far :woot:

This is something like running TRCD at 2. Only BH5 and UTT based ram can do it reliably at high speeds. Only a few types ram can run well and reliably with interleaving enabled.

Or is this completely wrong?

Well I managed it but it took .08v more to do it stable, must be extra load for the memory controller.

Something less than .1V on memory is basicly insignifigant. I wouldn't worry about killing it.
