Bios settings for 2 x 512 Winbond UTT

Recommended Posts

Hi,

 

Got my RDX200 all setup and its been trouble free so far. Got my opteron running 2800 no problem. However, I have been trying to take my RAM settings off AUTO settings but am not have any luck.

 

I know the RAM is good for 240 at 11,2,2,2 at 3.3 volts as I ran this on my Nforce 2 fine, however I just can't get it error free. The settings I am using are:

 

command per clock AUTO

CAS Latency 2

TRAS 5

TRP 2

TRCD 2

TRRD 2

TRC 8

TRFC 24

TRWT 1

TWCL 1

TREF 3120

TWTR 1

TWR 2

Read preamble 5.5ns

Async latency 7

R/W Queue bypass 8

Dynamic counter Enabled

Idle Cycle Limit 256

Bypass Max 7

DRAM Drive strength normal

DQS skew value 0

VDIMM 3.3

DRAM bank interleaving enabled

32 byte granularity AUTO (what is this? just left it as auto)

 

With all settings on AUTO, the ram is error free up to 260 mhz, but as soon as I adjust the timings it errors. Can someone reccomend some settings that will get my RAM stable?

 

Thanks

What Are your AUto Settings? Use A64 Tweaker to get them all and post a screenshot or list em.

 

 

My UTT needed 3.6v to get to 265 Error Free. at 2-2-2

twr 3

twtr 2

trtw 4

tref 200mhz 3.9us

 

read write queue bypass 8x

controller mode 128

ecc mode disabled

2t timing disabled

bypass max 4x

max async latency 7

read preamble 5.0ns

idle cycle limit 16 clks

dynamic idle cycle counter enable

 

all mem clk set to enable

Ram can do 225Mhz (crap I know) but Seems laggy seems timings really make a difference on the platform IMO anyway. Same ram does 290Mhz on intel setup.

As you can can in sig what the ram is I beleave its similar to the UTT stuff.

Hope this helps.
