Hi,

I just recently bought this built computer and here are its specs:

# AMD Phenom II X4 Processor 955 (3.2GHz) AM3

# THERMALTAKE HIGH PERFORMANCE CPU COOLER

# ASRock M3A785GXH/128M Motherboard

# 4GB DDR3 1333MHz PC3-10600

# Hitachi/WD 500GB 0A33437 SATA2 U300 7200rpm 16MB RoHS

# LG/SAMSUNG 22X DVD-RW DUAL LAYER W/LIGHTSCRIBE

# ATI Radeon HD 3200 FULL HD 1080p 512MB DVI/HDTV PCI-Express Video Card (Onboard)

# REALTEK 8-CHANNEL DIGITAL SOUND ONBOARD

# REALTEK 10/100/1000 Gigabit Network Card (onboard)

# OKIA 80MM CASE COOLER

# OKIA 550 WATT POWER SUPPLY

But when I use SIW (System Information for Windows) software to look up the information for memory, it shows that the speed is only 553MHz, why is that? I'm still a newbie so please be patient with me. Thanks.

Here's the memory summary I got from SIW:

Try setting your BIOS to default settings. Perhaps an upgrade would help as well.

Is that memory on the vendor's qualified list of RAM? If not, it could have compatibility issues with the board and not be reporting the correct speed.

are you OCing...if so stop...
go here and get CPU-Z 1.54
after downloading click on memory ...get a screenshot...then click on SPD and get a screenshot of that as well
good read here about Understanding System Memory and CPU speeds...
you can get your mobo users manual here...
on page 58 you will see how to set the ram timings to get to 667MHz...that equals DDR3 1333

I don't think it's on there but the memory is compatible with the board. I confirmed this with some tech.

Thanks for helping. I'm not overclocking the memory.

Here's the screenshot you wanted: http://img689.images...663/memoryj.jpg

There are 4 memory slots on the board, slot 3 and 4 are in use. Slot 4 is the same as slot 3 so I didn't put it in there.

did you download your mobo manual...did you read page 58

[overclick.cn]

I did read it. I just don't really understand it though. I went to the BIOS Utility and changed the Memory Clock to 667MHz but is that it?

[happyrock]

what does CPU-Z say your speed is now

[overclick.cn]

In the Memory tab, the DRAM Frequency reads 665.3MHz

screenshots please

Sorry. Here it is: http://img100.images.../3290/shotr.jpg

[happyrock]

thats it...your ram is now set to run at 1333MHz

I see. Thanks for helping. Have a nice day

your welcome...

To put it simply... DDR = Double Data Rate
