Your commentary would be correct if he used an AMD system, but he doesn't:

I'm 99% sure that what I originally typed is correct. He'll run 3Gb of ram in dual channel mode with the 1gb/2gb stick combo as long as he uses the right ram slots. He'll suffer a small performance hit, but nothing worth discussing.

All in all his experience will be improved.

So please don't correct me unless you're positive you know what you're talking about.

OK, had to edit this fast before I lost everything in a bet. LOL

I'm wrong, you're right. You suck!! LMAO

Again, foiled by not being up to date with the latest technology. Still though, he wouldn't be running true dual channel, he'd be running half and half...so I'm *cough* partcially right.

This is what the fuck I'm saying:

If Cal put a 512mb stick of ram in Channel A Dimm 0 and a 1Gb stick of ram in Channel B Dimm 0 THEN HIS MOTHERFUCKING RAM WOULD RUN FLEX MODE.

FLEX MODE = This mode provides the most flexible performance characteristics. The bottommost DRAM memory (the memory that is lowest within the system memory map) is mapped to dual channel operation; the topmost DRAM memory (the memory that is nearest to the 8 GB address space limit), if any, is mapped to single channel operation. Flex mode results in multiple zones of dual and single channel operation across the whole of DRAM memory. To use flex mode, it is necessary to populate both channels.

This means that the entire 512mb stick in Channel A Dimm 0 operates in dual channel mode. The bottom 512mb portion of the 1gb stick in Cnannel B Dimm 0 operates in dual channel mode with the 512mb stick, the top 512mb portion of the 1gb stick runs in single channel mode, AND ALL OF THE RAM WORKS TOGETHER.

As the post I made before stated, there is a minor performance hit to running mismatched capacities, but its always < 10%.

So again, in INTEL motherboards of specific chipsets, of which Cal's motherboard IS ONE you CAN AND MANY PEOPLE DO run flex mode dual channel memory DESPITE RUNNING DIFFERENT CAPACITY MEMORY STICKS.

Understand now?

Also, 2x512mb sticks and 2x1gb sticks = dual channel interleaved mode, which is the fastest ram mode you can have on an Intel Board. Just saying.

I know more about computers than you on a internet gaming forum

Yar, I understood it before you posted this. I saw you edited and added info to your previous post, then scrambled to edit my last post LMAO. If you looked at the .pdf manual I got my info from you'd see why I was arguing the way I was [Edited: *grumble grumble* took a closer look at the .pdf and read it more closely and found the section on interleaved mode so I was blowing smoke out my ass the whole time because I scanned over it and missed the juicy stuff. THAT my good friends is why we must all completely read the instructions before we make a fool out of ourselves on the world wide web! Do I at least get a cookie for admiting I was wrong? :P], especially with the 5 year old technology I've been used to. Haven't stayed up to date since I'm not planning on building a new one any time soon. (haven't upgraded because the durn machine still runs games just fine and I'm getting cheap in my old age)

And Cal, I for some reason had it in my head that you ordered a 1 gig stick instead of the actual 2 gig one you ordered. So, all that mumbo jumbo about ordering another of the one you had on order is wrong. Just do what Gaige said and I'll shut the F up. LOL

OH yeah, this is where I really need to insert foot into mouth.

As for the kid, mother and wordly possesions comment.....

I may or may not have had my fingers crossed, in the imortal words of Ronald Regan. I don't remember...

If you insist though...I gotta try something so here goes.

The kid is 11 years old, 5'6" and growing like a sprout since he just started puberty... clothing and food costs will be high. He'll be wanting his own car in a few years and of course there's college down the road.

The mother, well....imagine a white version of Eddie Murphy's mom in the Nutty Proffessor. Same attitude... She's old but not diaper changing time old yet, but in a few years who knows.......

As for the wordly possessions, ummmmmm...ummmmm well, I'm not paying shipping on them! That wasn't part of the deal so you'll have to pick them up!! :P

Desktop Boards - Single / Dual / Flex memory modes

^^^ This link specifically. His motherboard, the d925xcv, supports Flex Mode. That means 2Gb of his memory will run in dual channel mode, and 1Gb of it will run in single channel mode simultaneously. The additional ram combined with the bandwith improvements WILL result in a faster computer, not slower like you stated in your post.

You can apologize whenever you feel up to it.

Edit: Cal, your board has 4 slots that hold a max of 1Gb each, so the 2Gb stick you ordered won't work, you do need 4x1Gb for 4Gb.

So if I were you I'd get two of these:

Newegg.com - G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 667 (PC2 5300) Dual Channel Kit Desktop Memory - Desktop Memory

Thanks I'll order those tommorow.

Got your pm vcjester and thanks THANK YOU ALL 4 URE INPUTS!

Damn DDR2 is so fuckin cheap now, I couldn't resist, had to order 2 x 2gb sticks.

stryph · 05-12-2008, 01:12 PM

Not only that, there is a very minimal performance gain from using DDR3.

I have 8GB of DDR2, overkill yes. But it was cheap, so why not.

Letum · 05-12-2008, 10:57 PM

If I was running 64 bit os I would go 8gb.

Drelin · 05-13-2008, 02:52 AM

I stuck another 4gigs of ram (6gigs total now) in my system because of how damned cheap it is, AU$60 or something for 4gigs was just too good to pass up. It hasn't even affected my OC either, my 6400 is still running at 3.2ghz with complete stability but then the ram is basically running at stock speed anyway.
