Double sided VS Single sided memory ~ the holy grail

[THUGSROOK]

is there a difference? (canterwood / springdale)

here's a few sets of my benchmarks that ive posted in various (previous) threads that shows 2x doublesided is faster then 2x singlesided....


KHX3000 vs XMS3200

* P4 2.53B @ 180fsb
* GF4600
* P4P800 turbo MAM 2226 (springdale)
* KHX3000 2x 512mb 6ns pc2700 (2 sided)
* XMS3200 2x 256mb 5ns pc3200 (1 sided)


> 3DMark2001 <
2x 2 sided = 16078
2x 1 sided = 15995



KHX3000 vs KHX3500

* P4 2.53B @ 182fsb
* GF4600
* IC7 nbs800 street racer c2226 (canterwood)
* KHX3000 2x 512mb 6ns pc2700 (2 sided)
* KHX3500 2x 256mb 5ns pc3200 (1 sided)


> 3DMark2001 <
2x 2 sided = 16375
2x 1 sided = 16292

> X-Isle Tech Demo < 1024x768
2x 2 sided = 142.8
2x 1 sided = 142.3

> UT2003 Demo < 1024x768, flyby --- botmatch
2x 2 sided = 199.4 --- 91.7
2x 1 sided = 199.0 --- 90.5

> Quake III v1.32 < 1152x864
2x 2 sided = 318.3
2x 1 sided = 316.3

> Aida32 <
2x 2 sided = 5090 / 2208
2x 1 sided = 5083 / 1297


even this short amount of testing clearly shows a consistant difference between single and double sided memory on Springdale and Canterwood motherboards. so there is definately some truth to this.

is it worth spending huge $ on new ram? no
but if youre gonna buy ~ buy right and get doublesided

Thanks for posting your benches. Its a good addition to the article. This is the kind of info. that helps as I get closer to upgrading to a p4c/canterwood.

Ahh cool, thanks Thugs, I was surprised though that Anandtech just decided to come out with that article recently. Up until now I was always told that 2 sided was better, guess this just confirms it hehe. Go KHX users.

PS: You once told me that KHX3000 was their product specification code for their PC2700 ram. Are you sure? I have Hyper-x PC2700 and mine says KHX2700.

Agree. The difference is < 1%. Nothing that you would ever notice. If you are buying mem, 2 x 512 is the way to go anyway. 512 sticks are always 2 sided AFAIK.

You should post your results Here as well.

KHX2700 and KHX3000 both have 6ns pc2700 chips.

oldfart ~ ill post a linky

The differences are actually bigger, but I forgot the damn link...shoot. it was a good one too

AFAIK, the only double sided 256mb sticks are the OCZ PC3700/PC4000 Gold... If anybody knows of any other DS 256mb sticks, LMK.

yes i'm curious as well... thanks!

is corsair 256 3200 xms double sided - it has 4 chips on each side . Its just i heard it registers as single sided in memtest .

 

[Overkiller]

no it is single sided as far as i know even though it has chips on both sides. its one of those *weird things*

 

[Cenarius]

I believe "double-sided" is a term that has been used for years to describe RAM with 16 chips (non-ECC), 8 per side, so 8 chips is single-sided, but for cheaper manufacturing (smaller PCB), sometimes they put 4 on each side. Nothing weird about that!

Well, that explains why my PC2700 HyperX was able to take 8 hours of SiSoft Memory burn-in and 24 hours of Prime95 without a single crash at 180MHz. I think I will try for 185MHz next.

Anyone here have good luck getting KHZ2700 up to or over 185MHz?

my pair of KHX3000 was able to run 3dmark2k1 upto 443dcddr on an IC7 moboard.
couldnt do it on a P4P800 tho.
