Anyway to get more voltage to RAM on Intel motherboard?

[balane]

I have the below motherboard;

http://www.intel.com/products/motherboard/DP965LT/index.htm

I have an E6400 and 2 x 1GB of this;

http://www.newegg.com/Product/Product.asp?Item=N82E16820231098

Although it's rated at 1.8-2v and meets the necessary timing requirements my computer is very spotty when running at 800MHz. I throttle it down to 667MHz and everything is fine. I put this RAM into another computer and it runs fine at 800MHz.

I really need to turn up the voltage to my RAM so I can get it up to speed but Intel offers no setting for this in the BIOS. Anything I can do here? Mildy frustrating.

If I can't do anything about it how much of a performance loss am I getting by using 667MHz RAM instead of 800MHz RAM? Is it worth RMA'ing either the RAM or mainboard to correct? I really don't want to do this if possible.

Thanks.

mobo defaults are set at stock

RAM defaults are set at recommended mobo stock/capable from SPD

run anything out of manufacture specs and you're on your own!

some BIOS updates make it possible for mobos to stay much more secure or may offer more tweaks under manual adjustments, small increments won't hurt, but don't overdo with massive jumps, could dmg your chips

if the mobo lets you go past the volts, go for it, some RAM stick are good enough to handle it even if the label doesn't say so

overall, if you for sure know the RAM can run on the mobo, just adjust the volts and CAS and DDR standard yourself, and if the system starts and you do memtest, you're square~

=MOBO
Four 240-pin DDR2 SDRAM Dual Inline Memory Module (DIMM) sockets
Support for DDR2 800, DDR2 667, or DDR2 533 MHz DIMMs
Support for up to 8 GB of system memory
=RAM
Capacity 2GB (2 x 1GB)
Speed DDR2 800 (PC2 6400)
Cas Latency 5
Timing 5-5-5-15
Voltage 1.8V-2.0V

update the BIOS? or dump the mobo and get 3rd party stuff which is much more enthusiast friendly

besides, if you're just running stock, DDR667 vs DDR800 will not be that big of a difference for 2 gigs of RAM in dual channel

1: Your RAM won't run faster than 533 unless you have either overclocked the processor or are running it at a memory ratio other than 2:1 (sometimes shown as 1:1).

When going into your BIOS, hold Ctrl and press F1 and that should open up some more options for you to change things like memory timings.

I think you should update your BIOS, up the voltage on the RAM by +0.3 to 2.1v (entirely at your own risk, don't come crying to me), change the memory ratio to 4:5.


You can't RMA either the RAM or motherboard because nothing is wrong with either. There's no point in buying extreme fast DDR2 when your system simply isn't using it. If it's at 2:1 ratio with the FSB, your default FSB is 266 Mhz and this means your RAM will run at 533. To get that RAM running at 800 on the standard ratio you'd need to overclock your FSB to 400Mhz, which isn't something easily done on an intel motherboard. In real world situations, however, you won't notice much of a difference between DDR2-533, 667 and 800 unless all your other stuff is being maxed out. A few frames here and there maybe, a few second in winzip extracting.
