Windows 7: Kingston RAM Overclock?

Kingston RAM Overclock?

Alright, so I'm messing around with overclocking the CPU still but I've run into yet another problem. I have this:
Newegg.com - Kingston HyperX 2GB 240-Pin DDR2 SDRAM DDR2 1066 Desktop Memory Model KHX8500D2/2G

My issue is that it's clocked at 800 MHz while it should be at 1066. I changed it to 1066 via BIOS but I got a BSOD after POST. What is the issue?

Your CPU may not support 1066, nor may your motherboard.

*Due to AMD CPU limitation, DDR2 1066 is supported by AM3/AM2+ CPU for one DIMM per channel only. Refer to ASUSTeK Computer for the memory QVL (Qualified Vendors Lists).
Newegg.com - ASUS M4N72-E AM3/AM2+/AM2 NVIDIA nForce 750a SLI ATX AMD Motherboard Listed under Specifications.

I'm trying to link directly to Asus, but I'm having a hell of a time finding your board.

your ram voltage may be set too low your board , probably defaults to 1.8v , that ram is 2.2v , try upping the voltage to your ram as a starting point , also make sure its set to 2T in the timings section of your bios , it may be set at 1T as default.

the timings for that ram are 5/5/5/15 , try dropping them to 5/7/7/24

i assume you unlinked the ram from the cpu before setting it to 1066?

Running your memory at 1066 has more to do with the FSB and divider than it does with the actual memory. You will need to overclock your FSB and use the proper divider in order to run your memory at 1066Mhz. I like to look these numbers up and then unlink the memory from the FSB. You can usually get these numbers by going to a forum dedicated to your motherboard.

For instance on my board running my Q9650 at 4.05Ghz 1800QDR 450FSB using the 4:3 divider I run my memory at 1200MHz which isn't even overclocked for my PC2 9600 memory.

I think that did the trick! It's running beautifully now!

sweet It may have been a voltage issue all along so you might wanna try tightening up your timings again see how performs (back to 5/5/5/15) , leave it at 2T though

Well this is quite odd. For some reason, Windows shows yet another BSOD on start-up today. I have no clue what could have triggered it since I've changed nothing in the BIOS lately. I have yet to mess with the FSB and divider, maybe that's the issue?

Try setting your ram to the default speeds and timings detected by your BIOS but keep/change the voltage to 2.2v because you ram chip(s) is rated up till that voltage and Kingston will fully warranty your ram up until those voltages regardless the speeds your running your ram at. I think the BIOS detects the ram as DDR2-800 5-5-5-15 plus you need to change the ram voltage to 2.2v.

Download and burn Memetest86+: Memtest86+ - Advanced Memory Diagnostic Tool

IMPORTANT!
: Make sure nothing else is overclocked in your BIOS, e.g: CPU, FSB or PCIe and that all the voltages are at default besides the ram running at 2.2v before running Memetest86+.

Run Memtest86+ with the default speeds and timings detected by your BIOS with 2.2v as mentioned above for at least 2 passes, 3 passes is recommended in your case.

If all goes well and you get 3 passes without errors at default speeds and timings with 2.2v then your ram is not faulty and we can proceed to either overclocking you ram to DDR2-1066 speeds or setting the multiplier to 5.33x if your BIOS has that option for DDR2-1066 speeds. However, if you gets errors within those 3 passes then your ram is faulty and you need to exchange/return or RMA your memory depending what option you still have left.

Let us know what the results of Memtest86+ within 3 passes. And we can hep proceed to getting your memory at DDR2-1066 speeds or at least close to those speeds.

Good Luck!
