Alright here are my settings. In the bios I set it to- 1600MHz 1N 6-7-6-18-Auto-8-6- and the rest are on auto. My RTL is 47-50-51 with Elpida 50nm Kingston HyperX. This is the most stable for me and I hope this info helps. eva... I don't mean to take any thunder from this thread but could you pm me if you've noticed the new bios throttling your x21 multi to x20 on high overclocks with the D0 chips?

just wanted a double confirmation

yup seems ht off needs more.

also found seting pwm vtt frequency to increase 30 percent .. u can reduce the vtt.
Yeah i noticed with 4/28 increasing pwm vtt frequency to 15% bit more stability - while previous bios had no effect.. haven't tried 30% though.

I set it to DISABLED after having it on ENABLED and getting the same results. Thanks for the quick response.

::EDIT:: After reflashing my bios setting VR Current Limit Override to Enabled works.

......

tWR = 9 u get C to +2
but here is the thing
tWR for different rank and different DIMM in intel spec is 1-8 while same rank is 10-22
so why the bios has 1-31??

so what are we setting actually
default is 6
was this for tWTR in BIOS / Write to Read (same rank) in CPUTweaker ?

this is what i get:

4/28 + 6/16 BIOS @ 200bclk x10 mem 7-8-7-20

tWTR BIOS ---- tWTR (same rank) CPUTweaker
4 ------------- 15
5 ------------- 16
6 ------------- 17 (as auto)
7 ------------- 18
8 ------------- 19
9 ------------- 20
10 ------------ 21
11 ------------ 22 (max)


--------------------

for tWR (in BIOS)

setting tWR in BIOS changes tWTP (in CPUtweaker), but doesn't show any change to tWR (in tweaker).
there is no tWTP setting in BIOS to test.

4/28 + 6/16 BIOS @ 200bclk x10 mem 7-8-7-20

tWR 12 BIOS set = tWR 12 + tWTP 23 tweaker (same as tWR auto)
tWR 10 BIOS set = tWR 12 + tWTP 21 tweaker
tWR 08 BIOS set = tWR 12 + tWTP 19 tweaker
tWR 06 BIOS set = tWR 12 + tWTP 17 tweaker
tWR 04 BIOS set = tWR 12 + tWTP 15 tweaker
