800mhz ram only running at 667 - HELP!

[3xploit]

Just bought a pair of OCZ Reaper HPC 2x1gb (2gb total) ddr2 at 800 mhz. In the bios under memory configuration it says the ram is running at 667mhz, so I change it to 800mhz, restart the computer, and it crashes right after windows loads up.

My specs:
Core 2 duo e6300
Intel dg965wh mobo
ocz reaper hpc 2gb ddr2 800
60gb hdd
ati radeon x1600

Odd, double check the chips on the RAM, good their model #. Maybe you got weird sticks that were mislabeled or something.

 

[ZenZimZaliben]

Are these new sticks of ram in a new motherboard? Or did you upgrade to the reapers?

If you upgraded, reset the bios or force auto on all your memory settings.

http://www.intel.com/products/motherboard/DG965WH/index.htm (Does support DDR2800)

 

[xmountainxlionx]

have you done anything with voltage, those sticks might take more to run at the said speed. also maybe your timings need to be a little looser

 

[ZenZimZaliben]

That is why i say reset the bios. The motherboard should detect the ram as DDR2 800 and auto set votlages and timings.

ZenZimZaliben: These are new sticks on an old (1yr) motherboard. I upgraded from OCZ gold edition 1gb ddr2 667mhz. How can I reset bios?

xmountainxlionx: Nope, left the voltage at stock. Current timings are 4-4-4-15, but even at 5-5-5-15 i would get the blue screen after loading windows.

mrw1986: double checked labels, says its supposed to be at 800.

 

[xmountainxlionx]

try upping the voltage a little and see what happens

I had the same problem. I was told it has something to do with windows compatibility with 6400 ram. It works fine but crashes when set at 800mhz. By the way, mine was Corsair, but crashed just the same.

ive never heard that before, Ive seen people use all kinds of ram with xp and vista. maybe your thinking about 32bit windows limit to see more that ~3.5 gigs of ram

 

[ZenZimZaliben]

If you click on the link I embeded on my previous post there is a downloadable pdf which shows the exact location of the bios jumper...but usually its right next to the battery and has bios or reset printed on the board.

ZenZimZaliben: I've located the bios jumper. Should I set it to recovery or configuration?

 

[ZenZimZaliben]

To clear the CMOS:

Turn off all peripheral devices connected to the computer. Disconnect the computer’s power cord from the AC power source (wall outlet or power adapter).
Remove the computer cover.
Locate the battery on the board.
With a medium flat-bladed screwdriver, gently pry the battery free from its connector. Note the orientation of the “+” and “-” on the battery.
Leave the battery out for 10 - 15 minutes, for the CMOS to lose the settings.
Replace the battery in the connector, orienting the “+” and “-” correctly.
Replace the computer cover.
Turn the system back on.
You will need to reset the date and time in the BIOS Setup after clearing the CMOS.

This information can be found here...http://www.intel.com/support/motherboards/desktop/sb/CS-028780.htm
If clearing the CMOS does not resolve a no-boot situation, try performing a BIOS recovery.

Copied from other forum:
A common hardware issue with pc6400 that has been discussed frequently in
vista.hardware_devices. If you are running pc6400 reduce your dram speed to
667 and it should stabilize. The issue, if it is the one you have, shows up
when the fourth dimm slot is filled on some mobos.

Was this post

 

[ZenZimZaliben]

from what the OP has stated he is only running 2 sticks of ram.

 

[xmountainxlionx]

i ran 4gigs of PC6400 on Vista ultimate 64, no problem. maybe memory specific

 

[ntdouglas]

My buddy bought a 2g kit of ocz crossfire ram ddr2 800 and after alot of trouble shooting discovered it was ddr2 667 ram. Rma

Apparently it's my mobo...

http://www.intel.com/products/motherboard/ddr2/index.htm

"Only DDR2-800 memory supporting JEDEC approved 1.8V operation with timings of 5-5-5 or 6-6-6 is supported on Intel® Desktop Boards based on Intel® 965 Express Chipsets¹."

My ram runs at 2.1v guess i should have read that before buying my ram.

 

[Mussels]

Voltages are NOT auto detectable.

How high can the volts go on that mobo?

OCZ ram can run at 800 1.8v, it will just need looser timings - 5-5-5-18 or looser.

 

[3xploit]

I'm pretty sure you can't tweak voltages on intel boards, but I'll go back to the bios and put the timings to 5-5-5-18 and see what happens

Before you quit, try to create a custom BIOS with the Integrator Toolkit. Looks like you can "uncover" the options via a custom BIOS.

I have used this before for my D975XBX board.
