Bluenose 637

Hi all,

I've got my new rig up and going. Asus P5K Deluxe,4 gb Kingston RAM, Nvidia
GTS 8800, WD SATA 2 HDD, SATA 2 RW DVD, SATA 2 DVD, Intel core 2 duo E6850.
Win xp sp2 / Vista 32 dual boot

Got things up and running fine. But I started getting random CTDs in some
programs and the error message referred to memory issue (could not copy,
etc). I installed my old 3.5" drive and ran MEMTEST 86. Let it run all
night and sure enough I had some errors. I could not tell which stick though
so opened up the case and installed the sticks one at a time (total of 4)
and ran MEMTEST 86. No errors. So then I took one stick and move it to
each DIMM slot and ran the MEMTEST 86. No errors. 8 runs total no run less
than 6 hours (I seem to recall more than 15 passes).

The only thing I can think of is that there is a heat issue when I have all
4 sticks in and the cover on. The memory is "bare" does not have the heat
shields I have had on other memory. I have checked my MB temps and it never
seems to get above 125F when I am looking and is usually around 110F. My CPU
temp is usually about 100 - 105F under load, sub 100 when idle. My CPU fan
hangs around 410RPM. two other fans in the case - one 120mm on back and one
120 mm on top. Power supply is in seperate compartment with own fan. Fans
are only 3 prong so I can't see RPMs, but they are always running. Using
the fan control on the MB.

Do it look like heat or could it be something else I can check.

Is the memory listed on the Asus QVL ?

Try two known good modules next, for several days. Leave the case closed.
 
Hi Bruce,

Yes it is. I have the KVR800D2N5K2/2G the K2 indicates it is a kit of 2.
So that should be the same as the KVR800D2N5 / 512 on the list. Just the 2G
version. The 512 version is listed as working fine with 4 slots. I had not
thought about the fact that the 4 1G sticks might have issue with the 4
slots.
 
Add ` /pae' switch to the `boot.ini'` file.

Also check with Kingston for the voltage and ram timings for your ram, the
bios auto some times gets it wrong for example:
Corsair CM2X1024-5400-C4 (ddr2-667)
Auto: 1.8v 5.5.5.15
Real: 1.9v 4.4.4.12

Also what psu have you got?
 
Hi,

What does the /pae switch do?

I have an Antec Phantom 500. Essentially silent. Very quiet rig.

I'll check the voltage and timings from Kingston and manually set them.
 
With the Voltage on the memory up I'm not having any ctds. If I let memtest
86+ run for 8 to 10 hours i will generate and error or two. Not ideal. But
functional for now. If I am having issues again I can likely pull one stick
and go downn to 3 total and bring the volatge back down to default.
