The Be-All & End-All A64 RAM Article

Shows what the informed knew: Timings are important, but basically dividers have minimal effect due to the IMC.

Even @ 300 MHz synchronous the memory only holds a couple of percent advantage over 200 MHz asynch with decent timings. Sorry to anybody who bought ram for $300+ per GB. 🙁
 
THe review clearly shows that the DDR 600 outperforms DDR400 memory.... Thats a given... Major flaw in the comparision chart is that they dont have a DDR500 2-2-2 comparison which is much more common for overclockers using BH-5/UTT Ram.



 
whoa... awesome find.

And yeah, its almost comical at the people being suckered into buying that terribly expensive ram - and getting about 2% performance boost over cheap ddr400.
 
You gotta keep inmind that some people are all about benchmark scores.............. This is where the higher rated memory shines... Theres no doubt that in real world application the difference is minimal....
 
Yeah, really really poor article in my opinion. No 250-275 2-2-2, No 300-325 2.5-3-3/2.5.4.3, No mention of 1t or 2t, What it shows could pretty much be guessed, what people wonder about is mostly faster UTT then they tested versus tighter TCCD then they tested.
 
*Yay*

Running my ram with the 100 divider isn't all that bad then..

Running @ 2/3/3/7 1T helps as well.

So can someone bottome line something for me? What is the best RAM to buy if you are going with an AMD 64 solution (4000 or FX) and are NOT overclocking? Is there a better than average choice here? What should I go with?

If you're not overclocking, just about any ddr400 ram would work great. The point of the article and Zebo's post is that you can run your RAM with a divider for a marginal performance cost. This can save you lots of money due to fact you're not buying top notch ram to keep the 1:1 htt/mem ratio. In your case, your RAM will always run 1:1 anyways (assuming you are getting ddr400) since you're not overclocking. You can get 1gb corsair value ram for about $80 shipped. Or if you want tighter timings for marginal performance increases with this ram:

I would have agreed with the CVS recommendation, but I had some big problems with it. Also, Corsair uses different chips week to week, so it's never really consistent. However, some cheaper ram from Geil, G-Skill, Crucial, or anyone really ought to do just fine.
 
So now I really dont care about Voltage on my Corsair Value select 400 because i dont really need to overclock it anymore because a divider keeping my RAM around 200 HTT doesn't really effect my vids anyway? Sweet. After reading tons of forums, it looks like the single most benifit to my comp in gaming singlehandedly falls on Vid card. agreed?

4 Maxtor 250 (16Meg cache)s (NOT RAIDED...I'm crazy like that...Lots of POR...I mean Music)

Every game is like butter, I think the 16 meg cache on the HD's makes a world of differance. They hardley EVER get accessed during my game play after a map loads up. I noticed on friends systems, that most of thier "lag" was in diirect porportion to seeing thier hard drive light blinking..almost EVERY time! I play games using TEAMSPEAK and if My lil uber system 'LAGS" I can verify that it is server side beacuse everybody on TS will say, "Did you guys just lag?' Meanwhile when they ask If I just lagged I get the pleasure of saying 'Naw'
You gamers out there really should check out these drives man..forget about raiding RAPTORS seriously. My roomate just got one and I beat him into every map every time and he's pissed.
Benchmarking: I've uninstalled everything...It's all pointless now for gaming,all I care about is FPS never droping below 30FPS beacause thats what a televisions FPS is. The 6600GT does great and I dont need to run games at 34,976 x 23098 or whatever because the text gets to small anyway and so does my targeting recticle when Im aiming for you HEAD!

Thx all you guys for all your posts which I swear ive read them all while keeping my mouth shut and I am VERY VERY happy now.
For a gaming rig I swear...keep it simple and I newegged the WHOLE system for 1600$ and keep in mind that in November of 2004, I didn't evan know what FSB was!

Bye good luck...thanks ZEBO even though you don't know me (and L3p3r and others)
 
Chopper God: Welcome to the forums. Glad to hear that your rig is treating you nicely.

Please don't post one thing in a thread and then start a new thread with your post. Also, the hard drive access being decreased is because you have a ton of ram, not because the HDD's have a lot of cache-that would speed up the actual access itself if the cache has the data you need. Glad to hear that your rig is what you had hoped. It is sweet and especially for the price with that much storage. I like to see people (especially relative noobs) build their own and come out with a sweet rig @ a bargain price-that's what I'm about myself.

Yep, read it and have a lot of respect for Zebo. Thanks.

The difference is that this article takes the ram all the way to 300 (not that 290 isn't just about as good-I just like round numbers).

Xbit may in fact have taken Zebo's post as reference material, but I just felt that they did I nice job. Plus I thought that tools who may think that a post is not as good as an article may finally believe the truth.
 
i would like to see if high speed ram has more of a benefit on dual core systems, since logically they might need more bandwidth, or 754 systems, since they have less bandwidth to begin with.
 
Mike, 754 is not limited since it uses only about half of the available, theoretical bandwidth. The dual cores shouldn't have any problem either as long as dual memory channel is used.
 
Remember the testing was done at stock clock speed...You start OCing higher clock and higher HTT and that value crap will peter out and you will find it hard to even get 400ddr to even work at any divider and timings within limits of some boards vdimm options.....

I have seen it and it is regularly coming up in OCing threads...

So sorry I dont shar ethe comment to buy cheapest shite...I say get some good stuff that can run 400ddr at cas 2-2-2-6 range and you should be fine, but get cas 2.5 or even hgih cas 2-3-3-6 stuff at 400ddr and then push a 3000+ chip to a max and you may not get to run that ram at much more then 300ddr to get it to work memory free....

I said that 18 months ago when I was using cheapo Apacer with Samsung TCC4 chips with skt754 that cheap ram was the way to go, and I may as well have been talking to a brick wall. I have maintained for a long time now that enthusiasts grab hold of a mantra an stick to it, until you take a stick to it! E.G. the 50c load temp mantra or Artic silver/silver based T.I.M. being the only T.I.M anyone recommended. Some still haven't gotten the word that these are no longer necessarily the best option or correct guideline to follow.

 
This showed two important things.

a) ansync does'nt matter: look at the two bottom data sets are virtually equal accross board ones 1:1 the other 2/3

b) as my tests shown, you need a massive ~100Mhz bandwidth to equal 2-2-2 at low bandwidths. LL is king. Ideally you want both, which is what makes UTT king right now in 3dmarks WRs. These dudes always runs around 250-270Mhz 2-2-2 which only UTT or BH-5 can do. (async usually😉)

BTW guys 2.5 CAS @ 300Mhz is rare, most get 3 CAS (with 1T) which would have given the TCCD@DDR600 an even poorer showing.

True story. These are the 2 A64 guidelines in this generation of boards specifically. The low latency really does make the difference at 1T. Buy some UTT whether you are going to overclock or not, raise the voltage to 3.0 on the ram if you can, and bring the latency down as far as you can at stock speeds. That isn't overclocking, it is overvolting - which in the case of UTT/BH5 memory, is expected in order to get them to perform.

That's my 2 cents....

I want to sell my gskills and get 2gb of memory that can run cas 2 at 400ddr and I can about do it for the same price...My gskill PC4400 sticks rock on Intel systems and likely be who I sell them to....They were LE versions that can run 567ddr at cas 2.5-3-3-7, 600ddr cas 3-4-3-10 (best) and 400ddr cas 1.5-2-2-5....stcok speed of cpu on the last 2...6x300 and 9x200...the other one was ran at 7x283.....All in Dual channal and at 1t.....

I just want 2gb for my turn to X2 chips....as My CAD stuff and multitasking can really start making 1gb hit the floor now....
