GA 8KNXP low memory bandwidth

I figured it out!

It was an Advanced Chipset Setting called PSB Parking. Setting it to Enabled
significantly improved my bandwidth. At 220 FSB Sandra memory score went up
to 5100.

Definitely worth trying!

My biggest issue is with memory bandwidth.

I tried some new memory timing and crashed my system. Now regardless of

memory timings, or BIOS versions (F5, F6, F7E) I am unable to reach 5000
buffered. Before the crash I consistently timed in 5150 range. I am
meticulous about keeping OC parameter records and is positive that my
system
is setup identically as before the crash.
I've been playing with this for 2 days now, but this one stomped me!

System is rock stable.

I am having the exact same issue. i went through the 3 different
versions of the bios. i am using OCZ platnuim pc3500. i bought it
because of it ablity to run at tight timings but this motherboard
doesn't seem to want to cooperate.
my memory bandwith is stuck around 4900 in sandra.

anyone have any suggestions out there? do i have to buy a different
motherboard?

Michael,

My best numbers for both the overclock and stability a

2.5-5-3-3 at +.3v at 220 FSB. (~3300MHz)

After 8 hours of both MemTest and CPU Burnin runniung full blast I did get 1
memory error. I am willing to live with this.

BTW. I don't know of you guys got it from my previous post, but my memory
bandwidth issues we resolved with setting:

****PSB Parking to Enabled*****

I'm getting ~5,100 in Sandra now up from ~4,900.

I would be curious to see other's with and without the PSB Parking.

I bought the MB, CPU and memory all at the same time from a local shop. I
just told them I wanted 2gig of memory. They did select 4 sticks that all
had the same lot number, but it's just generic memory. Nothing fancy.

The shop installed the memory and CPU and fired up the combo on the bench
while I watched. Note, I didn't ask them to do it, they just do it as a
normal practice to show that everything works before it leaves the shop.

That way there's no question that the parts they sold all worked together
when it left the shop.

Beats the hell out of buying the CPU from one store, the MB from another,
and the memory from yet another source only to find out they don't work
together.

I haven't had to adjust anything with regards to memory settings in the
BIOS. Everything is as the default settings.

Having said that, here is the info from the ram

PC3200 512MB DDR
P/N: D512M400SA

The sticks are double-sided and each side has 8 Samsung chips
Each chip is...
Samsung 322
K4H560838E-TCCC

don't want to waste my time if it won't work.

I guess I'm the third. These are Kingston KVR400X64C3AK2/1G (two matched
sets, 2gb total) installed in slots 1, 2, 4, & 5 with the default bios
settings. System was initially set up with 1gb in June, then the second gb
installed in August, and has been rock-solid since. According to the
notification at POST, they are running in dual-channel mode, and I get
consistent Sandra benchmarks in the 4700 range.
