What happened to HyperX speeds?!!

I used to have 2x512MB Kingston HyperX PC3500 ram. On my rig I could set teh timings to 2.5-2-2-5, perfectly stable. CPUZ even said it was going at 2.0-2-2-5. I gave those two DIMMs to someone else and got two new ones. The only difference I could see visually is that the new ones have a little red kingston logo on them (the old ones didn't). Now, with everything the same, I can't get the RAM to clock at 2.5-2-2-5. I can only get 2-2-3-6. WTF is going on? Did kingston change the ram someway more than aesthetically or is this something I should expect? Here's my setup-

P4 2.6c
MSI 865PE, bios v1.3
HyperX PC3500 1GB
128MB Leadtek GeForceFX5900
Fortron 530W PSU
DDR Volt 2.65
AGP Volt 1.50
Dynamic Overclock- Private
Performance- Fast (PAT Enabled)
AGP Aperature 128MB
Everything else basic

Done some more testing, and best I can do is 2-3-2-5 @2.6volts. If I set RAS to CAS to 2, system refuses to boot up. Am I just stuck with this?

You probably ones you gave away probably had the great bh-5 chip in em. The ones you have now probably have ch-5 chips in em. The old bh-5's are out of production and are kinda rare.

Isn't it 2-2-3-6 better than 2.5-2-2-5 anyway?

I purchased some HyperX Kingston Memory at PC3200 it has the little red K as you state on your new PC3500 memory.

The BIOS default setting on these two 512MB sticks in my old Asus A7V9X-X were By SPD: 2.5T(DDR) 3T , 3T , 7T Because I had them written down on a note pad.

I now have the same memory in my A7N8X Deluxe motherboard but it is also set to SPD(auto) I would have to re-boot and go into the BIOS to see what they are at now but I can guess they are the same.

I seldom overclock my memory, courses in college proved to me that higher memory is simply a storage room for slewing around mucky numbers.

Overclocking ram just makes more mucky numbers faster. The trick to some motherboards is to set the S2K Bus Driving Strength out of Auto into Manual but playing with those 2 numbers found in Manual can cause CPU damage, you need to know what values to try.

Oh ya set your PIC or APIC into APIC mode this will use the enhanced chip-set on your motherboard and improve a few things. If your MoB is less then 2 years old simply set it to APIC the chip set will support it, faster reads from the CPU and control of the chipset.

Also set your UC/USWC to USWC <--ON

Another little thing you can do is set your monitor to DPMS off this will help the chip-set on the motherboard remain stable as it is reading AGP values constantly.

Setting your Monitor to keyboard wake up or sleep modes in the bios can cause instability but very seldom. In most cases on some of the new hybrid computers the older computers are rarely effected by this. Overclocked computers can be.
