Increase Ram Frequency from 533 to 800

Specs: Windows 7
[b]Hi Guys , ....... its my first post here
in this great forum

I have really Problem in my Ram Setting

I have GigaByte G31M-ES2C Rev 1.1 _ Bios Version F6



Intel Celeron 3.06GHz with LGA 775 Sock


it Comes with 2GB Ram DDR2 800MHz
but after 2 days it keep restarting with blue
screen ram issue

try to change OS many times to Windows 7 and XP
but there is no way to Solve it

So i get back this ram to manufacture and get
one Old Ram 1 GB with 667 MHz DiMM PC 5300


and from this day everything is great for 2 Month
but i want increase my Ram Size so i bought
DS2-800 D16- 2G 800 MHz


Working fine for 2 Hours only
Then it keep restarting again [img][/img]

Now i am very sure its MB Setting Bios Issue
Cuz when i log in to Bios Screen in MIT i see that[/b]

[quote][b]Robust Graphic Booster [Auto]
CPU Frequency [3.066HZ] (1.33*23)
CPU Host Clock Control [Disable]
CPU Host Freq. MHz [133]
PCI EXPRess Freq. MHz [AUTO]
Performance Enhance [Slandered]
System Memory Multiplier (SPD) [Auto]
Memory Freq. MHz [533]
System Voltage Control [Manual]
DDR2 OverVoltage Control [Normal]
FSB OverVoltage Control [Normal]
CPU Voltage Control [Normal]
Normal CPU VCore [1.30000V][/b][/quote]

[b][i]So how i increase my Ram Speed in Bios from 533 to 800 MHz
to could read my new memory

Thanks for ur time[/i][/b]

Your post is a mess & very difficult to read.

If you want to make a word bold, use italics, strike something out, etc, don't use brackets, use < and >.

And for links, don't use IMG,
use < a href="http://www.whatever. com">put description here</a > (spaces where left deliberately between the "< & a" & "a & >" so that it wouldn't actually convert to a link). Or you can just use the choices at the top of the reply box next to "Comments:"

Since you're having blue screen issues, the 1st thing you should do is test your RAM with memtest86. Let it run for at least one complete series of tests. If any errors are found, the RAM is most likely defective. Start by testing the sticks individually, then try them together. And make sure the RAM settings are correct in the BIOS. Do NOT use auto settings, especially for the voltage. Be sure to configure the settings to the RAM manufacturer's specs.

Anyhow, what you want to do with your RAM speed settings is incorrect. For best performance, P4's & P4 based Celerons should be run with a CPU:DRAM frequency ratio of either 3:4 or 3:8 (for 400MHz & 800MHz FSB CPUs)...4:5 or 4:10 (for 533MHz FSB CPUs). What that means is, since you have a 533MHz FSB CPU (133MHz frequency), the RAM should be configured to run at either 166MHz frequency (DDR333) for 4:5 or 333MHz frequency (DDR667) for 4:10. Anything else is less than optimal.

thanks for the link man but u said many
numbers and i am very confused

OK, I'll make it simple. What you want to do with your RAM speed is wrong...I'm sure that's why toxict51 asked what he did in the 1st response.

For your system with a 533MHz FSB Celeron, the RAM should be run as DDR2-667, even though it's DDR2-800. Anything higher or lower than 667 is less than optimal & you'll take a minor performance hit because of it.

And the RAM settings in the BIOS should be manually configured, not allowed to run with default settings or AUTO settings.

a minor performance hit man its wut jam said he meant negative way ur poc will be slow u might even have to reset ur bios
u cant run a ram stick of urs more than DDR2-667 eventhought its DDR2-800 its complicated to explain just when u go to the bios and ur memory config just make sure u set the value manually not auto config but watch out for the voltage anyways ur sticks could be damaged run some tests on em like jam suggested
