Asus P4P800-dlx and kingston hyperx 3500 512MB

Greetings everybody,

I have Asus P4P800-Dlx MB and one Kingston HX 3500 512MB memory stick on a
P4 2.4C system. I have had this setup for a while and I have not really
tried overclocking this system until now.

The most I can get out of this (stock fan) is overclock to 10% with "Turbo"
mode enabled. It brings to 2.6G CPU. That is great.

However, when I checked the memory using CPU-Z program, I see that my memory
CAS latency is only 2.5.

Here is the full CPU-Z's report on the memory:
Timings:
Frequency : 2x220.0 MHz
FSB:DRAM : 1:1
CAS# Latency : 2.5 clocks
RAS# to CAS# delay: 4 clocks
RAS# Prechage : 4 clocks
Cyccle Time (Tras): 8 clocks

Channels# : Single
Permonance Mode : disabled!!


My understanding was that Kingstong HX memory ran at 2-3-3-7 but I'm getting
2.5-4-4-8!!! That's terrible. I haven't really tested my memory speed in
standard mode (not OC'ed). I otta do that too just to make sure.

My CPU is running at 220MHz FSB with 879.9MHz Bus speed. I think this
number looks good too. The voltage reading CPU-Z shows that I'm running my
CPU at 1.5xx v.

I'm just not happy with the memory numbers.

I was thinking of adding one more 256MB KHX PC3500 memory and now I'm
considering another brand.

How can I get my memory numbers to run at 2-3-3-7 and how do I enable the
perfomance mode in Kingston HX 512MB PC3500 memory?

Your help on this is very much appreciated.

Thank you for taking your time to read my post.

Regards,
Naresh

All of the above seems normal. When you oc the fsb to 220 MHz and the DDR is
set at 1:1, it means you DDR is already overclocked too PC3500 has a rated
speed of 218 MHz!). So there is a great chance that pushing the FSB higher
will result in no-boot, whatever your cas settings. If you want to overclock
further, set your DDR at 5:4, and you should be able to reach a fsb of 270
MHz, although if the rest of the system could support such a high frequency.
You will probably get more stable oc results if you set the turbo mode to
normal.
Let your cas settings as they are (it doesn' t make a huge difference), set
your RAM at 5:4 and push gradually the FSB to 240 - 250 MHz. This will give
you a serious speed increase, and your system will remain stable.
Don' t forget to lock the AGP/PCI to 66/33 in your bios and to check
regularly your CPU temps.
If you add one module, you HAVE to install the same as you actually have, in
order to benefit from dual DDR, which will double the memory bandwith. So
don't worry about cas...<!-- ~MESSAGE_AFTER~ -->
