Kingston HyperX3500,A7N8X Deluxe,& XP2600 setting

[Rick]

I have questions about the above component's setting. Any suggestion!

1) I tried to run it @ 200x10.5, but the higher was only 195x11 running
Windows stable.
2) Am I overclocking it if the 200x11 is stable?
3) I can run it @ 180x12.5 = 2250 without any problem, but why couldn't @
200x10.5 = 2100.
4) The memory should be ok for @433 MHz 2-3-3-7. Temp is not an issue for
sure. What am I missing?

Bios setting:
195x11 Stable (Idle temp CPU=38c, Mobo=36c, Loaded temp CPU=41, Mobo=36)
memory = 2-2-2-5, vcore @ 1.65v and memory @ 2.6v.

200x10.5 (re-boot randomly)
Memory setting:
1 = 2-2-2-5, vcore @ 1.65v and memory @ 2.6v.
2 = 2-3-3-7, vcore @ 1.65v and memory @ 2.6v.
3 = 2-3-3-7, vcore @ 1.65v and memory @ 2.7v.
4 = 2-3-3-7, vcore @ 1.70v and memory @ 2.7v.

XP2600
2 x 256 Hyper X PC3500
Asus A7N8X Deluxe Rev.2 1.005
Power = 350W

Have you tried different memory combinations such as removing one and see if
the problem goes away. A chip may be bad.

 

[Rick]

No go even set the vcore @1.75v can't boot to Windows. I can boot into
Windows with 199x10.5, but it just won't work @200Mhz.

Rick:
Is the standard Vcore 1.75 on the 2600?

If you have a reasonable heatsink, you can play the voltage up by .25
increments. I did this for peak performance and then backed off to where I
felt the temps were acceptable.

Setting the voltage really helped get past some barriers. The XP2500 core
is 1.65 and it runs at 1.75 at 37 when idle, 41 under full load at mid day.

Hope this helps,

Alan

are you talking about the Dhrystone?
My SiSandra Arithmetic Dhrystone ALU shows as 7032 for a 2500+
200x9.5 (1895 MHz WCPUID)

I have a stick of that Kingston ram PC3500 and it craps out at
anything above 200Nhz for my FSB even though it should go higher. the
First stick I had just crapped out period after a week.

I have a stick of samsung 2700 that works fine in settings that the
Kingston fails.

I'm beginning to think their high end ram isn't so high end.

Those are great numbers, mine maxed out as stated below. Perhaps a separate
thread of numbers and settings would help everyone achieve more out of their
Asus boards.
Unfortunately for me, I am working through an A7M266 upgrade using my old
XP2000. It hasn't worked and crashed my A7N8X board as well to the point
that I cannot get a POST. Back to the store for a board test.
Really screws up sometimes! I am using the A7M board to send this message,
(now the original AMD1200 cpu.)(Sandra slightly over 3000)

I have questions about the above component's setting. Any suggestion!

<snip>

Seems a little hit-and-miss with this RAM. I've lay-buyed
some which I tested in-store and got very good timings with
it, no voltage boost, easilly got to 432 (216Mhz). Lucky for
me I was able to test the actual pieces I bought and
confirmed they were good. I've heard of others not getting
the results they should with KingMAX, esp. the PC3200. But
the 3500 is better stuff - they seem to be a little lax with
the ratings, passing off stuff that really shouldn't get the
ratings it does as high-end pieces.

I have a 512 stick of PC3500 and it won't do 1Mhz above 200.
I think I should contact Kingston for a replacement ??

 

[Rick]

I already returned it, and replace a pair of Buffalo PC3700 512mb. Run much
better now, and easily hit 210mhz. I really like these Winbond Module memory
w/5ns. They run rock solid and good price $99.00 ea @ Newegg.

PC3500 should do 216, if it won't then it's not meeting its
advertised spec's and you're entitled to a replacement. It's
not uncommon with Kingston these days, apparantly, but the
HyperX is supposed to be their best stuff (less prone to
this problem).

However, the reason it's not getting there could be to do
with memory timings... in BIOS there will be a set of
timings such as 7-2-2-2 or 7-3-3-2 or whatever. You didn't
mention if you'd tried adjusting these, but try slower
(higher numbers) settings. The KingMAX Hyper-X I tried works
great at 6-2-3-2 but fails at 6-2-2-2 (can't remember if
it's 6 or 7 in fact) at 216Mhz. (I'm just mentioning this in
case you hadn't come across it, sorry if I'm telling you
something you already know).

Try experimenting with these. 7-3-3-2 (if it's CL2; set that
last digit to whatever is the CAS latency of the RAM) should
be a safe setting to try, or even 8-3-3-2 to be sure of it.
If it has to go slower than that to get the 216Mhz I would
say that's not good enough either... this is supposed to be
performance memory and 8-3-3-x isn't exactly bleeding edge.
If these timings aren't available but there's options like
"Turbo" and "Aggressive" try using a not-so-fast setting -
"Optimal" or "By SPD" might do it. It seems on my board, an
Epox 8RDA+, those settings are only for the super-duper RAM
like Corsair TwinX PC3700, which costs almost 50% than
Hyper-X where I live. Even the KingMAX 6-2-3-2 couldn't
handle either Aggressive or Turbo.

If none of these gets you to PC3500 speeds, I'd certainly be
after either a refund or exchange. There are plenty of
stories of Kingston RAM not meeting spec's, however if you
do get a good unit, then it's quite good and not as pricey
as other premium pieces. I do appear to have been lucky with
the ones I got, but it goes to show it's always worth seeing
if the store will let you test it first before you buy. If
you got it mail-order, try slower settings yourself and go
for the replacement if you have no luck; you might be one of
the many people whose Kingston stuff didn't meet its
ratings. (Being able to try it in-store was the reason I got
this instead of sending away for Corsair).

This is the second one. The first failed totally after a few days of
use.

case you hadn't come across it, sorry if I'm telling you
something you already know).

I've used the SPD settings which are slower settings due to the other
stick being DDR400. If I just use the 512 samsung I can get well above
200Mhz yet the supposedly high quality KingstonX even by itself fails
at any settings, timing, voltage etc etc at anything over 200Mhz. ;(

last digit to whatever is the CAS latency of the RAM) should

Tried it all ;(
It was a real pain too since the only way I could get the PC to boot
if it failed was to pull the KingsX out and boot with the samsung ram
only .

Thanks for the INFO.
