Hi, I'm need some help
Prescott 2M 630 3.0G
2x1G Ballistix BL12864AA663.16FD2
SATA hard drive
Floppy (people still use these?)
I previously had an ASRock 775V88 on this box, but the cheap SATA connectors broke off forcing me to buy a PCI SATA card. The board absolutely HATED it and would crash/lockup/freeze/BSOD frequently. I didnt want to upgarde the vid card on this machine, so I thought the 775Dual-VSTA would be a good inexpensive 'fix' to my problem. Well it did solve the crash/lockup issues. Anyway, I had been using some Wintec DDR 400 PC3200 2x512, and I found I could get 2x1G Ballistix for only $30. Timing is 3-3-3-15 No brainer right? (The DDR 400 had performed flawlesly All [Auto] Dual channel CR2)
Get it installed, and I'm really busy. Then Crash BSOD. Uggg. happened again, then again, all while heavy memory intense spplications open, i.e. a dozen or so IE plus OE, windows explorer, and winamp. So I had to started doing some BIOS testing.
1. With the DRAM frequency setting to [Auto] it automatically sets it at 400MHz regardless of any other setting. FSB 200
2. With the Flexibility option set to [Disabled] I get errors no matter what, unless its set to single channel manually.
The RAM is 667Mhz Qualified, but when setting the frequency setting manually I always get errors. Just to make sure the RAM wasnt defective, I had it tested in a memory tester.Hard to believe I would get errors from this board with almost all settings on auto.
So, back to square one, and tweaking with theses settings. The more I get to looking, the more I feel out of touch because there is alot of these timing settings I have no clue about.
BTW I am using memtest+, and all the errors are on test 5 and 6. The errors are all above 1024M telling me that it is the timing in the second stick. Most often the errors are in the last 20M at around %99 on test 5.
Anyway, there is a good deal of settings for the RAM.
DRAM Frequency [Auto]
Flexibility Option [Disabled]
DRAM CAS# [Auto]
DRAM Bank Interleave [Disabled]
Precharge to Active (Trp) [Auto]
Active to Precharge (Tras) [Auto]
Active to CMD (Trcd) [Auto]
REF to ACT / REF to REF (Trfc)[Auto]
ACT(0) to ACT (1) (Trrd) [Auto]
Read to Precharge (Trtp) [Auto]
Write to Read CMD (Twtr) [Auto]
Write Recovery Time (Twr) [Auto]
DRAM Bus Selection [Auto]
DRAM Command Rate [2T]
DRAM Voltage [Auto]
Advanced Memory Configuration (The undocumented settings)
DRAM Drv DQS [Auto] (these seem to be address ranges)
DRAM Drv CS [Auto]
DRAM Drv [Auto]
DRAM Drv [Auto]
CLKBuf DDRA Group Delay [Auto] (These seem to be timing delays from 1x50 to 14x50 in pico seconds)
CLKBuf DDRB Group Delay [Auto]
CLKBuf FB_OutA Delay [Auto]
CLKBuf FB_OutB Delay [Auto]
CLKBuf DDRA Drv [3x]
CLKBuf DDRB Drv [3x]
CLKBuf FB_OutA Drv [4x]
CLKBuf FB_OutA Drv [4x] (I think this is a typo. should be 'CLKBuf FB_OutB Drv' even stranger the options are 1x,2x,4x,3x on both those 3 and 4 being out of order on both the last items:P)
I'm sure my solution is somewhere in these settings, but with great descriptions like 'Use this to set the blah blah blah, or use [Auto] to set the timings by SPD' You dont get a real good idea of what each setting does. The traditional settings I understand CAS, tRCD, tRP, tRAS, TRFC etc, but the ones under advanced I dont, and may well be specific 'labels' to this manufacturer/board. I have seen that sort of thing often in the past where different manufacturers call the same things by different labels.
So, I could search all night on the net to no avail, but I'm old, fat, and lazy Personally, I find it best when you dont know something, just ask.
So, to anyone out there knowledgeable, what the heck are all these settings under 'Advanced Memory Configuration'?
CPUZ reports the following under SPD
PS: I actually wrote this a few days ago, while writing, the computer crashed, an corrupted all my boot records on my primary drive. I had to install windows on an old drive, and run a recovery program to get my data. Man what a pain.
