I setted the frequency of the DDR 400 memory at 200 MHz on BIOS. But after saving, exit, etc. the next day on POST appear only 166 MHz (BIOS retained the value of 200 MHz !). Why ? Which is now the true memory frequency ? The parameters are: * RAM: a) 1 Gb, DDR 400 MHz, cl. 2,5, 184 pin; code MPXD42F-D8KTB (Kingman) b) 0,5 Gb, DDR 400 MHz, cl. 2,5, 184 pin (TwinMos) * Motherboard: EPOX code EP-8NPA7I, rev. 1.x, nVidia nForce4 4xchipset * BIOS: Phoenix Award, 2006 (2005 ?); the default setting was 166 MHz (Auto) but I modified this setting to 200 MHz, thinking that the memory tolerate this frequency by design. Thank you very much.
Check your memory speeds with Everest or CPU-z it should show the actual frequency. Only thing I could see perhaps that might cause it to be reported incorrectly is the different sizes of the 2 sticks
Hmm.. You might want to update the BIOS if you have not already done so. Like Mac Daddy says, you should verify the actual frequency using CPU-z or Everest.
-I changed in BIOS the DIMM Voltage from Auto to 2,5 V (permitted by memory design). No change on POST. -The frequency indicated by CPU-Z 1.42 is 164,4 MHz. -EPOX site is now inaccessible, but 2-3 months ago I read about some updates. I don't remember any important changes. Updating by Internet (with Magic Bios v. 2.0) don't work; EPOX don't answer to questions (supplementary I have...no courage to update the BIOS !). Thanks for yours suggestions.
Hmmm try this quick and message back I will search before work tomorrow for more info on your BIOS I think it needs to be updated but this will tell us. Boot with one stick and then the other and see if CPU-z reports 200Mhz.
Power BIOS features---Memory frequency: Options * Auto * DDR 200 100 MHz * ........................... * ........................... * DDR 400 200 MHz (my option) * ............................ * ............................
Have you tried this with each stick separately as I mentioned? Are you sure both sticks are DDR400 normally it would give the option DDR400(200Mhz) or DDR333(166Mhz)
Think everest this time would be usefull Download it here 1: Open the program 2: Go to motherboard section 3: Go to SPD subsection 4: Check if the modules are the same and theirs properties
One advantage everest has over CPU-Z is DRAM voltage monitoring (if the MB supports it), comes in handy sometimes when the board itself won't allow you to view it in the bios.
Thank you. 1. The frequency is 200 MHz for both sticks (absolutely sure; leaflets and CPU-Z - SPD). 2. Regarding the separate testing of memories...a good and simple suggestion, but I need to move the table, the case, many cables, screws, etc. Very reluctant !
OK and just had time to check the Epox site you may want to update your BIOS ... Three updates: 09/14/2005 Bios Enhancements & Fixes for this beta BIOS release: 1. Hide memory 1T/2T item for C0 version CPU. 2. Add DIMM over-voltage up up to 3.2v. 3. Set 200Mhz as default for 'Memory Frequency' by K8 754 Ex version CPU. 4. Add CPU overclock up to 450Mhz. 5. Fixed 'PWRON after PWR-Fail' function fail for F71872F. 6. Add Show Correct SATA hard disk string. 7. Patch system boot from USB FDD,and USB mouse enable in BIOS,PS2/USB KB can't work. 11/07/2005 Bios Enhancements & Fixes for this beta BIOS release: 1."Update CPU code" 2. Fixed SM bus has error after install driver in OS. 3. Added Speical I/O and USB park mode item. 4. Vdimm adjust check. 03/08/2006 Bios Enhancements & Fixes for this beta BIOS release: 1. Fxied system hang at S5 when using ATEN(CS-72E) KVM data switch. 2. Fix system hang when used PCI vga card and full screen logo enabled. DL page: Welcome to EPoX International, Inc. Home of EPoX Products in the USA and Canada. Reason I wanted to try one then the other is the different sizes and manufacturers. If the 1G is in DIMM slot#1 and 0.5G in DIMM slot#2 and you are assured they are both 200Mhz then I think your BIOS needs to be updated EDIT: Epox really needs to run a spell checker
BIOS and memory frequency Thank you. I know this list of updates. After testing on line the drivers (and also visible on POST) I suppose that I have two (from 3) updates. Because I have: BIOS Date: November 7th 2005 BIOS ID: 11.07.2005-NF-CK804-6A61FPADC-00-None The MB was buyed 2 years ago.
