Adjusting the SPD timings on PC3200 DIMM's ?
Is there anyway to adjust the SPD timings for RAM DIMM's ?
I know I could Adjust the timings in the BIOS, but the problem is I can't adjust my BIOS because it came with a limited BIOS from Compaq as you can read in this thread:
https://www.experts-exchange.com/questions/21789374/Compaq-SR1710NX-Motherboard-A8AE-LE-AmberineM-LOCKED-BIOS.html
The problem is my RAM has three different SPD settings:
133MHz(2-2-2-6) 166MHz(2.5-3-3-7) & 200MHz(3-3-3-8), but my Compaq MoBo is reverting to 166MHz settings/Timings, and I want to try and adjust the SPD settings on the actual DIMMs to only read the 200MHz setting/timings... can this be done?
p.s. I know this will most likely VOID my warrenty on these chips but there old and I don't care.
Thanks,

No thats not possible for your situation since you cannot force it to read what you want in the bios as stated there is no possible way to adjust the timing. The RAM should actually be going with the speed of the slowest stick in all the slots so your lucky your getting the middle road as it is sorry.

I've heard there is software out there that allows you to change the "EEPROM" mounted on the memory modual... the EEPROM modual contains the SPD settings BTW.
I just forgot where I found the software (one of thou;s late night browsing sessions) . :(

lets think about this, the memory supports 200mhz but the computer is only using it a 166mhz. The motherboard/bios will only support 166mhz... EEPROM on the memory is only used to report to the motherboard what speed(s) it supports. It can not force the motherboard into using any specific settings.

The computer does support 200MHz, I've tried other PC3200 DIMM's in this computer and they have run fine... it's this particular set of DIMM's thats causing the problems.

I found it !!! :D
The program I was referring to is called "Thaiphoon Burner" unfortunately, its homepage points to a Russian site (luckily it does contain English), but allot of discussions on the software are in Russian :(
By doing a Google Search for "Thaiphoon Burner" I was only able to scrounge up 1 site that discussed the software in English...

Any suggestions on how to find out how to use the prog?

BassKozz,
Glad you found what you need, btw you never provided your system model# for any of us to determine if it can support the speeds you were looking for.
I would still standby my orignal post with respect that the motherboard will determine the best settings for memory. I would think that the memory you have isn't compatible with your system and changing the spd/timmings will most likely cause system instabilty.
But for fun and experimentation I too would be interested in tweaking the memory speeds.
Let us know how it works out!!

Sorry I provided a link to a previous EE question here:

Which contains the System Model#.

According to this link:
http://h10025.www1.hp.com/ewfrf/wc/document?x=5&dlc=en&lc=en&product=1817035&lang=en&cc=us&y=5&docname=c00496280
My system fully supports PC3200/DDR400. Thats why I don't understand why it is reverting to PC2700 speeds. By adjusting the SPD settings on the DIMM modual I should beable to set only one setting for the PC3200 and not for PC2700 or less. This should force my MoBo to recognize it @ PC3200...
After much research, This Thaiphoon Prog is very complicated, so rather then trying to re-invent the wheel and simply adjust the settings manually, I will try and flash a DUMP found at this link:
http://www.xtremesystems.org/forums/showthread.php?t=85533
With a similar Corsair chip that only has PC3200 settings.
I'll let you guys know how it goes...
P.s. I bet you didn't even think this was possible :)

BassKozz,
I don't think I should assume your model# based on some other discussion...
"Thats why I don't understand why it is reverting to PC2700 speeds" - this is most likely caused by a mis-match in memory timmings. Your motherboard may not support 200MHz(3-3-3-8) timmings. the 3-3-3-8 is your key to why it's not working. A great site for memory configurations is crucial.com. For the best speed and stability I would recommend purchasing memory that is designed for your system. As I have stated before, for having fun/educational and experimentation go ahead and try changing the spd...
Again, we are only here to help you out, it 's not a game to who can answer by assuming and chasing down other discussions.

basskozz,
Thanks, did you memory setup?

I ended up RMA'ing the memory, to see if that fixes the problem, if not I'll flash it (adjust it's SPD settings).
I'll keep you posted.
