ok heres the deal...i hav a GB 8vt880p combo mobo which used to have two 512mb 400 sicks in the ddr1 slots...i chose to upgrade to ddr2 but was unabe to get and 533 sticks so i ended up getting 2x1gb 667 to put into the 533 slots...i was told it would be ok and it would ust run at the 533 speed and i was fine with that...but now i get either BSOD crashes or just plan resets evry few mins(more during startup). its definatly a ram problem as a windows ram diagnostic crashes or the text garbles when it runs...the actual ram is ok cause in another pc it works fine and the diagnostic completes ok. so heres what i need...to be able to run the 677 sticks without having to go and get a new mobo (case of other reasons that are irrelevent). if you need any more specs just ask.
Ive heard that modifying bios settings might solve this issue but when ive been told what options to change the names (RAS to CAS etc.) dont match up with the options i'm given so heres a list of what ive got.

CAS latency
Bank Interleave (Disabled, 2 Bank, 4 Bank, 8 Bank)
Precache to Active
Active to Precache
Active to CMD
REF to ACT/REF
ACT(0) to ACT(1)
Read to Prechache
Write to Read CMD
Write Recovery Time
DRAM bus selection (Dual Channel, Single Channel)
RDSAIT/RDSBIT selection (Auto, Manual(03)
DRAM command rate

if you can please tell me what effects trying your suggestion will hav on my performance and if i can in/decrease any numbers by one to test for stability.

thanks, jt3204

You may have already done this, but have you updated your BIOS to the latest version available?

1. yes i have
2. no improvement
3. memmory-kingston DDR2 667 2gb kit (2x 1g sticks)
mobo - GB 8vt880p combo
processor - its a intel p4 3.4ghz...i installed it but cant remember what model it was...the only things i can tell you is that it reads as 2 *virtual* cpu's in windows...and that its a LGA 755 socket
memory speeds - the sticks are 667 but the mobo only supports up to 533...i herd that it would just slow down to 533 and my boot screen supports the fact that its reading as 533 only. (also no change if i manually select 533mhz in bios)

thanks
 
If you can find it, try the FSB:Memory ratio. It should look something like a 6/5 or 1/1. If it is set to auto, it could be attempting to read the JEDEC standards which are imprinted in the memory DIMMS. Thus, if it reads those, it could be the cause.

To remedy this, you can try finding this setting, and manually set it to 4/3. Your processor is a Prescott core processor, and runs at an FSB of 200 mhz QDR. You want the memory to run at 266 mhz, which is 4/3 of 200. By setting your FSB/Memory ratio to that, it should force it to 533 specs. Be advised, you should record the default numbers of anything you change, in case you have to change it back. That may or may not work.

If not, then you may have to manually set your memory timings as well. Don't set them unless you have to, though. Here are some safe, default settings if you must try them....

***DISCLAIMER***You change these settings at your own risk. These are advanced settings and setting them incorrectly can cause problems which may force you to clear your bios to reset. You make these changes at your own risk and responsibility.

CAS Latency - 5
Bank Interleave - 4 bank
Precache to Active - 5
Active to Precache - 15
Active to CMD - 5
DRAM bus selection - Dual Channel
DRAM command rate - 2T

If I didn't mention them, then leave the other settings as is....

Any information I gave you here is based SOLELY on what information you gave me, and what I could research, based on what you did give. You did not give me complete information on exactly what your memory and FSB are, so I can't give you better specs to go with.

ok tryed the timing and no improvement...the only thing i found close to the ratio was "DRAM CLOCK" where i could select "266-DDR533" i tryed combinations of this and timings and no improvement...hope you have another idea up ur sleeve!!
 

Whats your voltage settings and what voltages does your memory work on? If the memory works at 1.8v then your system should work. If your memory requires 1.9~2.1v then you may have to adjust your voltage on your mobo. JEDEC standard DD2 works at 1.8v which your mobo will do but for some mobo's its the only voltage mobo's can work on. If your memory is 1.9 or higher try those voltages and leave the rest to auto. If your mobo does +1 voltage your starting at 1.8v so +1 gets you 1.9v and +3 would be 2.1. Do not go higher than your memory voltage on your memory box.

If this doesn't work set it to the lowest voltage on the memory box and try the others timing suggestions.

voltage on ram sticks is 1.8v and mobo is supplying 1.8 so i dont think its the problem...maybe the fact that its just plain reseting and not BSODing anymore might be a hint to someone??? like ill be doing something and one of two things happen...
1. pc resets just as if i hav pushed the reset button...no warning or freeze
2. pc completly freezes...no HDD light and power to some USB devices cease.

any other ideas?? im happy to try almost anything practicaal

[/fixed]

some of the information is supposed to be in "tables" so u might hav to use ur imagination eg. the timings table

hope this helps!!

PS. this information was recorded with everything in bios relating to memmory was on auto, or auto by spd

this post is really just to get this back to the top of the list for more people to read and HOPEFULLY solve my issue.

please people i'm all out of ideas...i thought someone would come up with a solution in like a few hours.
