Well...this is a bit of a long story, so I'll try and sum it up as best I can...
I've been having some serious issues getting this thing to boot into windows and hold even that amount of stability after a restart. A friend of mine had the same CPU/Mobo/Ram I'm using running at over 300HTT 1:1 at one point...so there's no doubt in my mind that I should be able to achieve what I'm striving for...290x10 1:1, as the CPU benches just fine on it's own (with the memory clocked down).
I've tried so many memory timing combinations my head is starting to spin.
First off, I've been in constant contact with the USA support rep for GSkill, bouncing ideas off of him.
We've come to the conclusion so far that because the previous owner had this stuff running faster then I'm attempting to, and because it boots at 200MHz 2-2-2-5 no problem, chances are that it's simply a BIOS config issue.
The following timings are what the GSkill rep directed me to:
Bios > Genie Bios Setting
FSB = 300
LDT/FSB Frequency = 3
DRAM voltage = ~2.7v
Bios > Genie Bios Setting > DRAM Configuration
MHZ = 200, 1/1
CPC = Enable
Tcl = 2.5
Trd = 4
Tras = 8
Trp = 4
Trc = 8
Trfc = 14
Trrd = 2
Twr = 2
Twtr = 1
Trtw = 2
Tref = 4196
DRAM Bank Interleaving = Enable
DQS Skew Control = Auto
DQS Skew Value = Auto
DRAM Drive Strength = 1 (or best for your computer)
DRAM Data Drive Strength = 2 (or best for your computer)
Max Async Latency = 8ns
Read Preamble Time = 5ns
Idle Cycle Limit = 256
Dynamic Counter = Enable
R/W Queue Bypss = 16x
Bypass Max = 7x
Burst Length = Enable
The timings were listed as a guide for the DFI CFX3200 board, but he also told me that aside from the DDS and DDDS he used all the identical timings with an RDX200 "back in the day" and it worked fine.
Because the guide is written geared towards the memory running at 300MHz I've decided to back down to 300x9 1:1 as my goal as opposed to 290x10 1:1. I've been having slight stability issues at 290x10 on air and this way if I can stablise 300x9 I should be able to just bump the voltage and HTT multi up to jump straight to 3GHz 1:1 when I get h2O on this thing.
But...back on topic. Initially the listed timings did not work for me, and I was told that it's more often then not the DDS and DDDS that need to be worked on. Problem is that I've tried EVERY single combination of DDS and DDDS (all 61 of them) with no luck.
I'm not sure what to look at next...but I am determined to get this working the way I know it can. Hopefully once I get it running at 300x9 I can leave the timings alone and move backwards a step or two on the HTT to 290x10 but we'll see.
If anyone has any suggestions or input as to what to try next I'd be greatly appreciative.
