got greedy, and put another 1gig stick of DDR400 in my rig.....

3gigs of ram....running in 128-bit dual channel. (2x 1gig DDR400 in Dimm 1 and 3 || 2x 512 DDR400 in Dimm 2 and 4)







....I almost feel dirty when I see the POST screen flash by stating dual channel 128-bit mode. :eek:
 
What type of DIMMs are you using?

Congrats on your purchase!! I am using 2 X 512 MB TWINMOS DDR400 DIMMs and I am thinking of adding 2 more 1 GB DIMMs. Keep me informed!!!!! ;)
 
Mmm....did you see an increase in gaming performance? I'm curious to see 2GB vs 3GB on games like Battlefield 2 and Quake 4.

using all GEIL brand 184-pin DDR400 PC3200 ram sticks.

PC's now updated and current specs are in my signature. :p :D

EverQuest2, F.E.A.R, and HL2/CS:S seem to run flawlessly. I also 'turned off' the Windows XP page file.

So far, no errors or adverse issues. PC seems to run smooth and quick. I've only had current system build for the past two weeks. This is a total system build from all new parts other than re-using my original PC Case, CD Drives, and floppy drive from my previous setup.

current PC specs are in signature.
 
I didn't think Dual Channel would work that way. Each stick has to be the same in each bank no?

Or is it that each stick has to match to their related back (1&3 - 2&4) as you listed?

So could I have 1GB in bank 1, 512MB in bank 2, 1GB in bank 3 and 512mb in bank 4 and have it work in DC mode? if so, I've got that extra gig just sitting around!

A=C, B=D. Your second scenario is fine, where 1+512 and 1+512 will total three gigs in DC.

yes

1GB in bank 1, 512MB in bank 2, 1GB in bank 3 and 512mb in bank 4

thats how it works
but
slot 1 and 3 have to have the same ram/specs
also
slot 2 and 4 have to have the same ram/specs

so you caint use
slot 1 kingston 1gig value ram 3-3-5-8
slot 3 corsair 1gig xms 2-2-3-5

ect ect

but you in my expernce you cn use diff brand in the DC slots
like corsier in 1 and 3 and kingston in 2 and 4

well good luck and 4 gigs is goin to be in my rig all will be the same each stock will be ocZ 1gig ......series each

w00t:p w00t :p

Some mobos work that way, slot 1+3 or slot 2+4 for dual channel. My old mobo was like that. Depends on the mobo though. You can usually tell if your dimm slots are different colours. Might wanna check your board. Can never have too much ram :D (well upto 3gig anyway, until vista turns up)
 
Gotcha.

Each pair matches (1GBx2 Patriot - 512MBx2 Corsair XMS), the Patriot is DD400 the Corsair is DDR 433, I would assume the Corsair will just drop down to match the Patriot?

I'll let you know my findings when I get home. I don't think I really need 3GB of RAM though =D

Surprisingly, it does work that way with my mobo, I REALLY didn't think it would, but got the 1gig stick anyway just satisfy my curiosity. I stuck it in and booted it up and BAM! It showed dual channel 128-bit mode!

But yeah, I have a stick of GEIL 512mb DDR400 in Bank 1 and in Bank 3, and a stick of GEIL 1gig DDR400 in Bank 2 and in Bank 4. :)

I believe you are mistaken. Note that all of your RAM works with the same latencies when plugged into one system, regardless of individual capabilities. What "specs" refers to, is double-sided vs. single-sided DIMMs. This is determined by the "geometry" of the ICs. Just as hard drives are comprised of cylinders, heads, sectors, landing zones, etc (CHS notation), so too are memory modules. A 512MB stick can be made out of 32Mx8 or 64Mx4, referring to the combination of data width per chip, with the number of chips per DIMM.

There is also nothing wrong with mixing brands, so long as your motherboard doesn't have compatibility issues with any of the individual sticks.
 
I added the extra RAM and it posted, I went into the BIOS and adjusted some settings and now I am locked out of my rig, I can't get it to post, no beeps at startup, nothing.

It's been ages since I've tooled around in my PC, I need to clear the CMOS (jumper) or remove the battery on the MOBO to reset the settings to let me back in? The damn battery that is sitting under my second ATI card taking up the whole damn case?!

Since you said it's been a while, if you're going to take out the battery, make sure you unplug it from the wall also. It's way easier to just find the CMOS jumper and clear it.
 
i have a gig stick and a 256 stick in my lappy and it says im in dual channel... weird

I unplugged it from the PS, it hasn't been that long ;)

I had take out my secondary X1800XT as it was in the way of the jumper and the battery. :rolleyes:

Everything is back up and running with the extra RAM (in DC mode, so the BIOS says). Now to find the settings for the RAM on this mobo (finding out what they mean is a whole new ball of wax).

The 2x512MB are DDR433, the 2x1GB are DDR400 (Patriot), they are all running smoothly (under load, well under D&D Online) at 433. On boot it says the ram is running at 433 DC Mode. It doesn't however, mention 128 bit. I've seen tha toften in a lot of posts, how does one find out if it's running that way (or is it a given)?

Grats in getting it to run!

Some mobos say 128-bit some don't. But if your mobo posts that it's in DC mode then it's a given that it's 128-bit mode.

Single channel DDR does 64-bit up/down. When you run Dual Channel.....it's doubled.... 64-bit up/down per channel. (128-bit).

(well that's how it was explained to me. I'm sure there is a more 'technical' explination, but heh, that one works for me!) :D
