hi, i have brought a Gigabyte GA-MA770-DS3 mobo, it has 4x1.8v ddr2 1066mhz ram slots, i have been having trouble finding ram to fit this, is there any way i can tweak the voltage to 2.0v+
Or.. can you link me to a uk site that sells these (2x1gb DDR2 1066Mhz 1.8v)

thanks
 
Most PC26400 has a SPD program to default to 1.8v. Some extreme high preformance DIMMS from Mfg.'s like OCZ for example may not have this feature. So, you can install one DIMM in slot 1 and boot the computer in BIOS and set the memory voltage manually to 2.0-2.1v. Then install the other DIMM(s) and run at MfG. Guaranteed specs. You have a Nvidia chipset which are more RAM 'picky', you might want to run your MB through a RAM configurator and find MFG. 'guaranteed' to work DIMMS.


All these Crucial DIMMS are guaranteed to run in your specific MB.

Having your memory properly volted in BIOS insures the DIMMs will run stable and not cause system crashes when under load and also insures the memory will run at the speed and performance the manufacturer guarantees, example PC6400 4-4-4-12 @ 2.0-2.1v. Sooooo many people on this forum buy OCZ, Corsair, Crucial, Titanium, Dominator, Ballistic, etc. DIMMs, stick them in the slots and ask, 'why won't my computer load windows OS? Why all these stop errors and BSOD? These high performance DIMMs require adjustment and proper voltage to run with stability and to perform properly to load an OS. PC6400 default voltage of 1.8v is not going to run 'Titanium' type labeled RAM requiring higher voltage as high performance RAM always does.

ok thanks alot everyone i will have my computer finished soon, im currently looking at the ATI 3870 512mb, question time, 3870 512 or 9600 768?
practically the same price which is better? you reply and i listen :)
 
These DIMMs are sold and guaranteed to run at CAS 7 Latency at 1.8v. Many PC28500 1066 Mhz. DIMMS are sold guaranteed to run at CAS 5 at 2.0-2.2v. This is what I was trying to point out. As an example, I have a P5B-VM DO 965 Micro board and the voltage regulators will only allow up to 1.9v upward adjustment in BIOS. If I put my PC26400 4-4-4-12 @ 2.0-2.1v in the slots, I cn only get them to run at 1.9v 5-5-5-5-15...the system BSOD if I try 4-4-4-12! That's what I'm talking about.
