 Posted: Mon Jul 31, 2006 2:13 am Post subject: NF7-S2 - Can it use high-density memory chips? |
 |
|
Motherboard: Abit NF7-S2
Current memory: Two (2) 256MB PC-3200 low-density DDR (slots 2 & 3)
Question 1: Will high-density DDR memory modules work?
Most of the DDR sticks that I've put into this box had 8 chips on them
(i.e., low-density). I've seen sticks selling that are high-density
where:
Chip Configuration: 128x64
Chip Density: 128x4 (High Density)
So these memory sticks only have 4 chips on them which means their
geometry is different (but their addressing should be the same). Will
this mobo handle them okay?
Question 2: Will dual-channel mode work with 3 memory sticks?
For dual-channel mode, I'm supposed to put a stick in slot 3 and
another in slot 1 or 2 (so each stick is on a different memory
controller). What happens if I populate all 3 slots? Will I still get
dual-channel mode (maybe across only slot 3 against the combo of slots
1 and 2, or maybe just across slot 3 with only slot 2 and slot 1 is
separate)?
In upping my memory, there's no point in keeping just one of the 256MB
memory sticks. I'd go with two (2) 1GB memory sticks if that's what I
need to keep dual-channel mode but I'd prefer to fill all the slots and
go up to 3GB. |

From the manual, the motherboard supports a maximum of 2x1GB DDR 400
in slots 3 & 2 dual channel mode, OR it supports a maximum of 3x1GB
DDR 200, 266 or 333.

No or maybe - for example if you put 1x1GB on one channel and 2x512MB
on the other channel, dual channel may or may not work.

You need to figure out what is best for you, 200FSB with 2GB or 166FSB
with 3GB.

Oh, crap. I didn't see the "Supports 2 DIMM DDR 400 (Max. 2GB)" when I
reviewed the manual and forgot about that limitation. Guess I'll stick
with two 1GB memory modules so I can stay with DDR 400. Thanks for the
reminder. That eliminates the question about dual-channel mode working
or not with 3 memory sticks since I'll only be using 2 sticks.
However, I haven't found anything in the manual that specifies support
or non-support for high-density memory modules (8 versus 4 chips).
I suspect the manual was written before high-density memory sticks (4
chips) were available so it is probably based on the low-density sticks
(8 chips). Wondering if anyone has tried and successfully used the
high-density memory on this mobo. |

If the NF7-S2 is anything like the NF7s v2.0 good luck getting two
high-density DIMM's to work in dual channel at 200Mhz. I've had nothing but
troubles with NF7s v2.0 since I went to two, high-density, 1GB, PC3200
DIMM's. It won't work at 200Mhz in dual channel (maybe if you relaxed the
timings to ridiculous degrees) on my NF7s v2.0 w/the stock BIOS. I had to
use the mantaray BIOS and turn CPC on.
