Guest Alan T Posted August 8, 2007 Posted August 8, 2007 I got 2 x 1 GB DDR400 in my system. Then added another identical 2 x 1 GB DDR400 RAM, now when the PC boot up it shows DDR333 in the first boot up screen. I tried to remove the old 2 GB, it shows DDR400, so the new RAM is OK. Any idea?

And the make and model of the motherboard is? What does your motherboard manual have to say on the subject?

Guest Alan T Posted August 8, 2007 Posted August 8, 2007 Re: RAM speed change from 400 to 333 in BIOS Yes, I think so. My original is 1 GB is Hynix DDR400 1 GB is Hyundai DDR400 Basically they are the same brand. Then I bought another 2 x 1 GB Hyundai (Hynix) DDR 400 I just wonder it should be allowed for different brand RAM provided they are DDR 400?

Guest Doug Knox - [MS-MVP] Posted August 8, 2007 Posted August 8, 2007 Re: RAM speed change from 400 to 333 in BIOS Even within the same manufacturere, DD4 400 RAM can be different if the model number isn't an exact match. While it seems wasteful, if you can't install the exact same RAM module for an upgrade, you're better off replacing everything to get the new amount of memory you want. -- Doug Knox, MS-MVP Windows Media Center\Windows Powered Smart Display\Security Win 95/98/Me/XP Tweaks and Fixes http://www.dougknox.com -------------------------------- Per user Group Policy Restrictions for XP Home and XP Pro http://www.dougknox.com/xp/utils/xp_securityconsole.htm -------------------------------- Please reply only to the newsgroup so all may benefit.

Guest Alan T Posted August 8, 2007 Posted August 8, 2007 Re: RAM speed change from 400 to 333 in BIOS The interesting thing is: My original 2 GB RAM give me DDR 400 reading in BIOS/first screen. Added total to 4 GB RAM give me DDR 333 reading. I removed original 2 GB RAM, ie, leave the new 2 GB in slot, give me DDR 400. It tells me that both new RAM are DDR 400. Why it give me DDR333 when they come together?

Your problem could be how your motherboard handles the dual channel RAM setup, this is why I asked you about the make and model and what your manual said, have a look at http://www.techspot.com/vb/topic24044.html
Guest Alan T Posted August 8, 2007 Posted August 8, 2007 Re: RAM speed change from 400 to 333 in BIOS OK, I think I need to look at the manual tonight. My motherboard is ASUS A8N-E nForce 4.

If this stops the machine from booting just pull the MB battery out and reset the BIOS back to the defaults. One other thing, unless you are running a 64bit operating system you are only likely to see about 3.25Gb or so of your RAM due to the fact that the 32bit O/S's reserve the memory addresses above that point for device drivers and devices.

Guest PowerUser Posted August 8, 2007 Posted August 8, 2007 Re: RAM speed change from 400 to 333 in BIOS The 4Gig limit should not affect the RAM speed. This is a very curious issue. Maybe one of the modules is not running at speed? (Try combinations to narrow it?) Most likely, it does appear to be a mobo restriction. Check for BIOS updates too, Alan.

In the BIOS configuration, under Advanced, CPU configuration, DRAM Configuration. Look at page 2-21 of the MB manual
Guest Bob Knowlden Posted August 9, 2007 Posted August 9, 2007 Re: RAM speed change from 400 to 333 in BIOS I didn't find the same listing for your board, but I'd bet that it's the same feature as for an A8N-SLI: http://support.asus.com/faq/faq.aspx?no=FFC7FB3A-68C0-6372-EE3B-D9013EB965D3&SLanguage=en-us which says: To be more compatible and stable with some memory modules, the default clock will be at 333MHz if four DDR400 memory modules are plugged on the A8N-SLI. But you still can set at 400MHz manually in the Bios to gain better performance. Moreover, in order to get best performance and compatibility, please choose those memory modules which are verified by us. You can get the QVL from the link below. http://www.asus.com/products.aspx?l1=3&l2=15&l3=148&model=375&modelmenu=1 Return address scrambled. Replace nkbob with bobkn.
