How would I tell the speed of the current memory? I know it is PC3200 and I suspect it is CAS2 :dummy:

Speedwise - you know it's PC3200, so that's fine.  It's just an indication of the highest front-side bus speed the memory can support.  PC3200 = DDR400 = 200MHz front-side bus.

For the RAM timings and CAS latency:

From windows use something like Lavalys Everest (Home Edition) or SiSoft Sandra to report on the memory.

Otherwise, enter the BIOS (hold DEL during power-on) and you can see the RAM settings under Advanced > Advanced Chipset Features

The A7N8X manual states that it allows all three slots to run PC3200 memory, which is good.  I just need to check now whether latency mismatches between DIMMs hose dual-channel completely, or if it just means everything runs at the timings for the DIMM with the highest latency figures.

Hi guys

My mate Ranger found this info:

If you goto this link Crucial website - crucial motherboard scanner,

You can either input your board etc if you know it or below that is a Scan my System button:
 
- it will tell you what memory you have
- what memory is in which slot
- max memory your mother board supports etc
- board manufacturer and model
- which memory is compatible
- and which memory they have in stock etc so you can order it and you know it will be compatible etc

Really useful as both Ranger and I are buying 2 gig of ram at the weekend.

nb: it downloads an active X control

Hope its useful.

Nice tool.

Apparently i can have upto 3 gig

Think i went over the top with 2 SLi Pci Express Graphics Cards and 4Gb RAM   But hey it works  

[Sn00ks]

Yup a good tool. Though it says I've got memory in slots 1 and 2 when it is 1 and 3; and it doesn't tell you what latency it is. It also says that I could add upto 2Gb PC3200. I'm sure when I checked the BIOS it said that it's running at CAS 2.5  :blink:  
Though the BIOS memory settings are set to auto and the latency option is greyed out. But will it run in dual channel mode if I stick the 2 512s in slots 1 and 2 and 1GB in slot 3?
Confused of Sheffield?


Talking about latency. I went to Maplin to see what memory they had , because I was bored this lunchtime, and saw that they had 1GB PC3200 for £99, so I asked the blok what latency was it. Dumb looks all round, no-one knew what I meant so they checked their database and found a reference in the FAQs to the 512MB RAM being 2.5 but I said that didn't apply tothe 1GB so they rang their techie helpdesk and they didn't know what latency was!  :roflmao:   :whistle:

get yourself a copy of Sisoft Sandra and run the "Mainboard information" module. It will tell you everything you need to know about your memory.

here is what it says about my memory:

"You are old and forgetful"  :roflmao:

Sorry it actually reports:

It is free

Download the lite version.

cpu-z is a decent little proggy that'll tell you all kinds of stuff about your mobo & ram, find it here

Has shafted my Firefox profile :ranting:  :ranting:

[suicidal_monkey]

crucials scanner doesn't recognise my mobo and the manufacturer isn't there Sparkle made the dam,n thing but I think they then decided not to admit it

Right, I've asked around and it should work in dual-channel in the configuration you've said.  Get another 1GB PC3200 stick and set your memory timings to the largest latency figures of the three DIMMs.

E.g if the 2x512MB are working at 2.5-3-3-7 and the 1GB you buy can only manage 3-3-3-8, then set the whole lot to run at 3-3-3-8 in the BIOS.  The 512MB sticks won't mind being given a couple of extra clock cycles to get their data out.

Even if it doesn't end up working in dual-channel you'll still have 2GB total RAM .  And the dual-channel gain isn't all that much anyway in real-world terms (it looks great on paper though).  Relatively speaking, the greatest system improvement will be by getting the extra gig in there.

OK Thanks Cadaver. I'll run Sandra Sisoft thingy and check the timings on what I've got and then purchase a suitable 1Gig stick.  

[Sn00ks]

Right Sisoft says my memory is Bank 0 : 512MB DDR-SDRAM 2.5-3-3-7 2CMD. So looking on overclockers they have a 1GB stick that is CAS2 with 'Memory timings of 2-3-3-6' Is this what I want? What do all the numbers mean?   :unsure:


EDIT: I've got two of them there 512MB sticks.

That stick should be OK if you set memory timings in your BIOS to 2.5-3-3-7 (ie the slowest timings) so that all sticks match. Dont use SPD (serial presence detect) as it will cause confusion
