GA-8KNXP Memory errors

I have just put togeather a new PC based on the GA-8KNXP motherboard revision 1
and am having trouble running the memory at DDR400.
Using MemTest386 I get errors in the bits 000000x00 range where x is usually 2
but not always. Get about 222 errors per pass on test #5.

I have tried GeIL Golden Dragon and Mushkin Black and get the same results. If I
manually put the memory speed down to DDR333 it works fine with no errors.

I tried increasing the DIMM voltage to 0.1 and 0.2 above manually as well with
no change.

There is definatley a problem because things are not stable. Games especially
that are stable on my other PC crash all the time with the ram at DDR400 but
stable at DDR333.

Any thoughts out there what my problem could be? Could it be the CPU?

If you haven't already, disable "Delayed Transaction" in the BIOS. That

As a note, I have tried three different 8KNXP boards, all Rev 1.0, with two
different brands of memory, and only one of the boards could run the memory
at DDR400 without errors. On the other two I had to run the memory at lower
speed. There are definately problems with 8KNXP and DDR400 memory.

John,

Is this memory brand listed on Gigabyte's Recommended Memories List for this
board?
If there is an Optimized Performance setting in BIOS, turn it off.

Where abouts is that?I looked at changing the memory timings but there does not
seem to be a menu for it. Tried pressing ctrl-f1 which some suggest brings up a
new menu but does not on mine.

The shop I brought it from says his KNXP has failed 3 boards as well. He is
change to a 8I75 and is looking at that and may recommend that I change mine as
well. If it doesthen I will expect it under warrenty as the board is suppose to
do DDR400 and it certainly dont.

Hi John,

1. Sorry, typo, I meant "Top Performance" menu. Some BIOS's have it.
I do not remember for this one. It's in the BIOS main menu.
Actually, this slightly overclocking causes similar problems.

2. Check out Gigabyte's site for recommend memory for this m/b.

HTH,

Hello John

I use Corsair XMS 3200C2 1GB set (2x512MB) in DDR mode and have always
experienced problems with the original 8KNXP Rev 1.0. Let us say that I had
4 of these sent back for RMA. The last board I got was a Rev 2.0 and it is
far more stable on memory and the other problems I had previously
experienced. Thanks to John7 with regards to this "Delayed Transaction"
setting in the BIOS as disabling this has enabled me to at last get decent
performance levels on my premium RAM. Prior to this using numerous timings
the best I could get in AIDA32 was read of about 3700 MB/s and writes of
about 1300 MB/s. Now with this disabled I am getting read of about 4400 MB/s
and write of 1450 MB/s. I bought a Aopen AX4C Max board to use while the
Gigabyte was away and found these latter speeds were what I was getting with
this motherboard and it has always bugged me that I could not get anywhere
near these speeds from this board which technically should be better. BTW I
have a P4 3 GHz 800 FSB CPU not overclocked.

If you enter the normal BIOS setup on the GA-8KNXP then hit ctl-F1, and look
carefully, you will notice a couple menu's have changed and some entries
under the menu's have changed as well. You are now in the Advanced BIOS
settings.

IIRC There is a menu on the top right hand side fot Top Performance (or
something similar).

Be VERY careful there. If you set that option on, and you have anything but
perfect high-performance memory, you will be left with a system that does
nothing but beep rapidly at you until you remove the cmos battery, wait,
then put it back in and start all over with default BIOS settings.

I have seen numerous posts from people who went out and bought premium
memory only to have lots of problems with this board.

I on the other hand, bought my GA-8KNXP , 3.2Ghz cpu, and 2gig's worth of
DDR400 memory (4 sticks of 512meg) all at the same time from the same
dealer.

I did not specify and particular brand of memory. The dealer simply chose 4
sticks of generic DDR400 memory (he did select 4 sticks all from the same
batch).

Dealer installed the ram and the cpu there in the store and bench checked
the combination while I watched. I didn't ask him to do it, it's just
something they normally do to insure both the dealer and the purchaser that
everything worked when it left the store.

The system has been running 24/7 flawlessly since day one. no memory
problems at all no matter what test I throw at it.

The system runs with all stock settings in the BIOS. no timing nor voltage
adjustments ever made.

Domenico,

You'r right, there is no 'Recommended Memory Support List' for GA 8KNXP.
Odd, I'd expected one (hint ... Gigabyte).

Although not appplicablem you may use this one for guidance.
http://www.giga-byte.com/Motherboard...echnologyGuide
_73.htm

In general, for these high speeds nowadays, stick to brands, avoind
brandless / oem's.
The BIOS 'Top performance' may cause troubles with more than one dimm, if
so, disable it.
