No actually in some instances it increases it due to the way the memory interact s and the the way the data is transmitted to the Memory controller in the cpu.

You mean the Drive Strength or the performance? Cause increasing the Drive Strength is the thing Im just trying not to do. If it's about performance, yeah. Certain lower timings dont automatically translate to better performance. When I had the A64 3400+ Clawhammer with OCZ PC3700EB I remember tRAS lower than 10 and higher than 10 gave worse performance than tRAS of 10.

It also could be that Transend Memory does not completely play well with DFI Motherboards that just may be the case as DFI Boards are very picky with Memory!

Haha, yeah, DFI is quite picky, especially combined with AMD CPU's. But with some tweaking things gets less worse

Im now running back at 2.3V again and set all Strengths to 1.0x apart from one, was set to 1.25x (can't remember which one anymore though) however it looks like I picked the right one as it booted up. Will post later on which one I changed.

However, Im thinking right if I set all those settings lower the Drive Strength becomes lower too right? I mean, it looks like a multiplier so lower multiplier would give lower... yeah lower... wtf Ive no clue.

Maybe Drive Strength is more about the Ampere trough the slots? Higher Volt with same Ampere gives more Watt which might be the thing killing D9's. If Ampere is lower Watt's will be reduced too. But Ive no clue on that. I just would like to know whether Im actually decreasing or increasing Drive Strengths the way Im changing things now. At least I set the DRAM Drivers Weak Mode to Weak, that's for sure weak then

Well its like this .....If you feed High Voltage to you're Ram in return you must give your CPU more Voltage as well. So in essence AMD processors "Prefer" Lower voltage memory thats just the way it works perhaps a thorough reading and understanding of the Architecture would be a wise move for you

YOU Must learn How the Memory Communicates with the Memory Controller if you want any success on AMD Platform without damaging you're components!


Balance is the solution Wood Pecker , not Voltage!

I found a PDF of AM2 CPU's with a lot of info. Also how RAM manufacturers should program the modules to work with AM2. However the fun part is it's all written in strange program language and not making any sense to me.
