Hi DFI reccomedns these

http://eu.dfi.com.tw/Product/xx_pro...E=MB&CATEGORY_TYPE=LP&SITE=US&PRODUCT_ID=3471

However cant find/ afford some of them so i am looking at the following.

G.Skill 1GB DDR ZX PC3200 (2x512MB) CAS2 Dual Channel Kit (F1-3200PHU2-1GBZX) (MY-002-GS) £70.44

Corsair 1GB DDR XMS3200C2PT TwinX (2x512MB) CAS2 (MY-030-CS) £72.79

GeIL ONE 1GB (2x512MB) PC3200 BH5 CAS1.5 (GOW1GB3200DC) (MY-055-GL) £82.25

Or at a push

Corsair 1GB DDR XMS3200XL Pro TwinX (2x512MB) CAS2 (MY-050-CS) £94.00

Will be used with a 3200 venice and will be overclocked.
Cheers

I would go for OCZ or Gskill with the DFI tbh.

OCZ 512MB PC3700 Platinum Edition EB-DDR CAS3?

Come on Si. If you're going to do something, do it properly... CAS3

Well i did post some cas 1.5 that would work with the dfi but it is only PC3200.

Is this going to be a gaming rig? If so I'd ditch all the 1 gigabyte kits in favour of a cheap 2x1Gig set, use a memory divider and clock away, you'll get much better results.

Not mainly a gaming rig as for the moment it will only have a cheap pci-e graphics card in so not sure if i need 2 gig of memory.

What are you going to be doing with the system? The A64 platform isn't bottlenecked by memory bandwidth so RAM isn't hugely important.

Just going to be used mainly for photo editing, light gaming and just internet etc.

In that case I'd be tempted to go for Geil Value or something cheap, 2x512mb kits aren't going to hold their value much as people are needing more memory. Geil Value runs tighter timings than rated 2.5-3-3-7 is fine with these modules, and they'll clock to 225-235 too.

Surely it would be possible to buy another 2x512mb later on and have 4gb of memory? Or is this not advisable.

The Geil One bh5 is amazing ram, its rated at both PC3200 @ cas 1.5 and PC4000 @ 2-2-2-5. You'll need active cooling but that isn't a huge issue.

So if i got the Geil one are you saying i would need fans near the ram for added cooling to keep the sticks cool?

cymatty · 29 Apr 2006 at 15:42

ajgoodfellow said:
Yep

To maintain these speeds the BH5 memory in the Geil One requires huge voltages (3.4V). This makes the sticks run rather hot so they must be actively cooled

If you don't want to actively cool the sticks get the Geil One TCCD stuff - this doesn't require the huge voltages and active cooling

Don't get any Corsair memory though as this is notorious for causing problems on DFI motherboards

Cheers for the help, would i just be able to clock the sticks from pc3200 speeds rather than upping the voltage to 3.4v to get pc4000. :confused:

ajgoodfellow said:
You can just keep clocking the sticks but they'll need the extra voltage to stabilise at the higher clock speeds. PC4000 is only 250MHz though so you shouldn't need such high voltages

I'd personally get the TCCD Geil One though

Are they more expensive than the geil ones i posted before, budget is tight.

ajgoodfellow said:
Ah - yes but only by about £10-15 when sold

Here's a link to the manufacturer's website

As they've been out of production for some time now it's hard to get hold of them though unfortunately

So the giel ones i posted are a good bet if i cant find these others for a similar price, and run them at pc4000 with a 80mm fan over the top of them?

cymatty · 29 Apr 2006 at 15:57

ajgoodfellow said:
Yep

They don't require a huge amount of cooling so a low rpm silent 80/120mm fan will be fine

Cheers if i rum at pc4000 what fsb is that? would it be able to go higher if my cpu does so i dont have to use a memory divider?

Thanks again for the help.

ps just seen this DDR 500MHz CAS 2-2-2-5. so take it it will run up to that speed.

You could think about running the same as in my sig if you want 2x512 or OCZ4800 plat elites(which are the same). No divider needed and it does clock even higher if your cpu needs it. At 2.5-4-3-6 1t x300htt 1:1, thats pretty fast, and it shows in all benchies.

How much do they cost?

Edit £150 ouch a little expensive.

kitfit1 said:
Yes i know, not cheap, but they are very very fast and they scale all the way up to 320htt 1:1. I don't know of any ram that fast at the moment.

Will i see the benefit it my cpu only clocks ti 2.4-5ghz. :confused:

ajgoodfellow said:
It'll only be slight though, and not worth the £70 extra over the other stuff mentioned IMO

Thats what i thought, the geil one stuff is out of stock and that would run 250mhz stock.

cymatty · 1 May 2006 at 00:39

Whats this stuff like?

Mushkin (991440) eXtreme Performance (2x512MB) 1 Gb XP4400 [email protected] Redline Kit

Seems to me like the geil one stuff, whack huge voltage through and it will fly?

Very good stuff, especially in the DFI's. There is one downer on it though, when your running with high vdimm it can burn out the cpu's memory controller so to get round it you have to pump more vcore through the cpu. There is a calculation that can tell you what the vcore should be for a given vdimm, if you do a search at "DFI STREET" you will find it.

Cheers will have a look.

Also what do you call high vdimm on the memory?

I've just bought a 2GB set, so I'll be putting the 1GB BH5 in my sig in the MM soon....

Damm just bought the Mushkin (991440) eXtreme Performance (2x512MB) 1 Gb XP4400 [email protected] Redline Kit.

Edit- bought a fan for them as well.

Ok read the article and apparently

(vdimm/2)-.325v is safe.

So if i run my memory @3.3v it works out as
(3.3/2)- .325=1.325v

So what does the venice run at normally?

cymatty · 2 May 2006 at 10:43

kitfit1 said:
AMD says 1.35 to 1.4, so it looks like you should be safe. You can of course put more vdimm through that ram if you have to and that's were you need to bear that calc in mind.

Is it safe to put more v through the processor?

Venice runs at 1.4V stock, I'd be comfortable using upto 1.5 on the stock air cooler, 1.6V on high end air and 1.65V on the average watercooling setup.

Ah that ok so doing the calculation backwards

(1.5v + 0.325)*2 = 3.65v vdimm

So if i run my cpu at 1.5v i can run my memory up to 3.65 which should be fine? As i have read the memort i am getting "only" needs 3.5v to run at 500mhz.
