By the way my system specs are:
enermax 420 noisetaker psu
msi k8n neo 2 platinum ( latest bios )
athlon 64 3200+ winchester on coolermaster hyper 6
2x512 geil ultra x
pny 6800 gt 256mb

*i inserted my dimms on slots 1 and 2. dimm slots 3 and 4 wont let me boot into windows for some reason ( blue screen, on stock settings )

To start my overclock adventure, I changed my timings to a very conservative 2.5-3-3-7 1T, and set the voltage to 2.8v.
Then I also changed the HTT to 4x.
The Agressive Timings in Cell Menu were also disabled.
Nv ati speedup, and dynamic overclocking and spread spectrum, and cool n quiet were disabled also.

After this I booted into windows.
I used clockgen to change my multipliers down to 9x, and raised vcore
to 1.450 to make sure that cpu is not a bottleneck.

Afterwards, with clockgen, I increased my bus by 5mhz increments
until I lock up. Upon each 5mhz increase, I run super pi 2M test.
But sadly it locks up or reboots at 235mhz.

Additional note, even at 218fsb, I cannot complete a super pi 2M calculation
test. It blurts out an error about rounding.

after this I also tried 2.5-3-3-10 2T mem timings, I also changed dram
strength to weak.
I even increased vdimm to 2.85. But it was no help at all.

On my ocz pc 4200, I used 2.5-4-4-7 at 250 fsb on 9x multiplier
with no problems, prime stable overnight.

I hope someone can enlighten me.

Does this mean that not all geil ultra X's are tccd?
 
By the way, with divider set to 166,
I can run 260fsb on 9.5 multi with 4x HTT, dram strength normal, spread spectrum off
memory on stock 2-2-2-5, 2.65v.
that means that my cpu is not the bottleneck in my problem.
 
Cheek the temp on your memory. I have used the same ram, and ran into early thermal unstability. Had to remove the heat spreader pull the compound then reaply A.S. Improved performance significantly..
 
DONT try unless you are very comfortable with this. It is a easy way to toss your mem. The hard part for me was the sides crimped over the pcb. That made it a little difficult. I used a small hard plastic flat head, put constant preasure on both sides of the spreader. Got a little space between them, than it was home free from there. Remeber DO NOT try this unless you are comfortable with this, if not you can distroy your dimm..

Good luck!
 
hmm, ive read somewhere that the new geil ultra x pc 3200 are not tccd anymore.
can anyone confirm this?
sigh... :(
