Title: Memory did say 1066MHz during post, now shows 800MHz
Post by: Iowabucks on December 15, 2009, 09:09:13 pm

Hey everyone, new to the boards here. I have a question about my Corsair memeory and Gigabyte mobo.

I'm using the GigabyteGA-MA790GP-DS4H mobo, with Corsair Dominator DDRII 4090 MB 1066 MHz ram. Also running Vista Ultimate 64 bit SP2.

When i first built this rig a year ago i remember seeing the ram in post saying 1066MHz. Now it says 800MHz. After it was built i was running XP. Shortly after i migrated over to Vista 64 bit. I also followed a Vista tweak guide but don't that had anything to do with it. I also flashed my bios somewhere during that time.

Looking in the bios i don't see anywhere it can be changed at. Is there a hidden section of the bios that i can access to change the frequency?

Does this sound familiar to anyone?

You will have to manualyl change ram timings, volts then fsb/ram ratio (not sure if thats same on AMD) to get your memory to run at that speed.

then set your timing and volts and youll be good to go

After a tip from the Gigabyte techs, i checked the memory specs and it should be running at 2.1v. I upped it from 1.8v (default) to 2.1v and it didn't help. On a whim i tried 2.2v and it did work. I now see 1066MHz in post. 

Should i be looking at the timing too?

Oggmonster--- Ctrl+F1 gets me nowhere, just to the help screen, which is the F1 button.

after i replied to your post i got to thinking.so i checked my bios setting (ga-ma785-ud3h) and took a few pics for ya to look at and see if you overlooked anything
press ctr+f1l from here www.pontsplace.us/images/main.JPG

then you can inter Dram configuration from here www.pontsplace.us/images/ram.JPG

from what i can tell about your ram your timings are 5.5.5.15 2T
but you should check the sticker on the ram itself to make sure
here's what it will look like www.pontsplace.us/images/timings.JPG

i hope this help ...

I've tried it a bunch of times but cntl+F1 does nothing for me. The second picture looks like the intelligent tweaker section, same as i see. I have the multiplier set on the highest setting to get to 1066MHz. For now, i have my dram settings on auto. I really don't know what any of those settings mean and don't want to get in over my head. I do want to learn though. Should i be able to find some chart on the Corsair website with all those settings? If i could match them up i would give it a try.

Hi
Ctrl+F1 Is very discrete, (slight flicker on bios screen) MIT as per 2nd image,
Google (memory settings ) and search these forums,
Merry Xmas
