thanks Shimmishim, ive been looking at some 1gig sticks, these might tempt me near pay day 😀

EDIT: from XS ... >>"1. sierra_bound | 2x1GB Crucial Ballistix Z503 - Micron -5B D | 3-3-3-8 1T @ 304MHz | 3.0v | Link! - SPi 32M Stable: Yes"

wow :shocked:

yes. amazing!

now let's stick back on topic here.

oh... btw, ocz is releasing a 2x1 gig set as well. except theirs should be able to do 3-3-2-X timings 🙂 should be out in a few weeks.

First of all the only time it reverts to DDR333 is in the older chips (Winchester, Clawhammer, Newcastle). THe Venice chips fix this with an updated memory controller.

As for the 2T -> 1T. Ok you find me more than 2 boards that Intel makes that can run 4x Sticks at 1T. There are only like 2 boards out there that have accomplished that before. Not only that with the on-die memory controller and the huge bandwidth the the HT Bus provides the difference is <=3%; which you CANNOT NOTICE AT ALL.

I've got 4 x 512M OCZ Platinum sticks in an A8N Premium, and I'm about to sell them on ebay and buy 2 x 1 G. I can only get the 4 sticks to run stable (and I'm not even confident that it is stable) at DDR333.

The one program where I seem to get the biggest loss with 2T is AutoGK. I get a 7.5% differance between 1T and 2T with all other settings the same.

2T 1 hour 15 minutes 16 seconds

 

[CheesePoofs]

I posted a tread about this before seeing this one 😱

My question is, if you overclock a winchester and use a 3/4 divider and 2T timings, will 4 sticks of ram work? Specifically, I'm running 273x9 = 2457mhz, ram is at 204.75 mhz with 3.4 divider. Should my memory controller be able to handle another two sticks of ram if I set it to 2T timings?

 

[stevty2889]

It couldn't hurt to try, but most likely with a winchester, you won't be able to get 4 sticks stable at 200mhz, since it defaults to DDR333 @ 2T with 4 sticks of ram.

sorry to go off topic again, but do you have any idea how these will OC?, and what timings they can do at DDR400, CAS 2 ?

Most kits should hit about 270 or so at 3-3-2 timings. Unfortunately, loosening up the timings won't really help them go any higher.

At DDDR400, you might get CAS 2, but most likely CAS 2.5.

I have run 4 x 512 on my DFI board with my 3700+ san diego.

It will run ddr400 with 2T.


4 x 512 on DFI with winchester, clawhammer, chip w/o SSE3 or improved mem controller will run DDR333 with 2T.


As for 2T vs. the whole 1T issue...

In synthetic benchmarks 1T is better than 2T.

In real life aps, 1T is barely better than 2T.

If you're proud and you need the most performance, 1T is for you.

If you don't care, then 2T is no big deal.


4 x 512's are fine.

I actually ordered 2 x 1 gig sticks as to eliminate running 2T (i'm one of those proud ones. 🙂)

There are some really nice 2 x 1 gig sets which are capable of running ddr600 or 300 1:1 with 3-3-3-X timings... but lets not get into an argument about timings...

those are single-sided Dimms are they not?

has anybody been able to run 4x512 double-sided DIMMs on Venice at DDR400? anyone? anyone? Beuller?

I'm asking because orion32 earlier in the thread is running an X2 4800+ (new mem controller) and his double-sided HyperX PC3200 dimms are being knocked down to DDR333.

it seems like every single person who answers in the affirmative actually has SINGLE-sided, not double-sided sticks

I have still not seen any evidence from anyone that 4x512 double-sided sticks will run DDR400 on any A64 controller, so naturally I'm holding off buying any more till I can get a definitive answer

I am not sure what kind of proof you need, I myself am running 4 x 512 double sided @ 400! The board will set timmings to 333, but can be changed to 400 manually!

Read the thread. Actual benchmarks don't show a noticeable difference. Sandra and Memtest aren't useful apps. Even in SuperPI, which does like fast memory, you can see for yourself that the difference is insignificant.

doesn't matter Winchester or Venice, etc.

only matters whether RAM is single or double-sided

i.e. double-sided RAM 4x512 on Venice=still DDR333

I don't know about running 4x 512M at DDR400, but I am able to run 4x 1GB at DDR416. 😉

Any Rev E CPU doesn't have the downclock problem anymore. That was one of the updates they made (meaning, it doesn't matter if your RAM is single or double sided, if you fill all 4 slots, it will not downclock to PC2700 speeds).

:thumbsup:

 

[the cobbler]

lol, good enough for me, that was all I was looking for really

was just reading up some more in an attempt to fully understand this for myself and it looks like Orion32 probably has 1T already set in bios before installing RAM possibly, which would cause boot at DDR333?

just so I understand what's going on here, if you were to install 4x512 with the bios already set to 1T, it would knock down to DDR333. If 2t, then should BOOT at DDR400? or if not, be changed manually?

(I am reading things even as I type this)

now I think i am starting to get it 🙂 finally

two more questions:
1) do the E6 allow 4x512 1T (not that I want one, just out of curiousity)

2) it might seem obvious to some, but seriuosly, am I better off with adding two CorsairVS for 4x512 2T, or would 2x1GB 1T be a better solution? roughly same cost either way).
Bearing in mind that the 512 sticks are rated 2.5,3,3,8 while the 1GB sticks of same/similar are rated with CAS 3 or 4!

maybe I should bite the bullet and just get 2x1GB Ballistix

the thing that confuses me about that is does the winchester memory controller default to DDR333 with 4 sticks because it can't run the ram at faster than 166mhz or because it needs to run the ram at 3/4 of the HT. If its the first, then overclocking won't help anything, but if the second is true, then overclocking the memory controller will allow you to run the ram at faster speeds (like 200mhz) as long as the HT is high enough so you can use a divider to hit that speed.

 

[orion23]

Thanks for the help guys!

The RAM runs now at 400 2T from the 333 it was before.

All I am showing you is that in the pic that the link takes shows you that he is running 4 x 512 @ 400, your question was awnsered there!

It's the memory controller thats the limitation, but that doesn't mean it won't work sometimes, so it never hurts to try.

PLEASE STOP THE FLAME WARS!!!!!!

You're full of crap. You can't notice a 3% difference.

Yeah whatever dude, like you would know what I have seen with my PC LOL!!! :disgust:
There is a noticeable differents when I go from 1T to 2T, I see it most when the PC is booting. My best friend has a similar setup with a Venice and he told me himself that he can notice a differents. I dont where you got your information, I have seen the difference first hand and no @$$ hat will tell me any different.
