Need some settings for 4x512 BH-5 on DFI Expert

[Ub3r-L33ch]

I'll have to use 4x512 for awhile until I can get the 2x1GB sticks I want.

Cant seem to find any settings other than default to get this stuff to work. Using DDR 333 and 2t. 2-2-2-5

Any ideas what I can try? Right now my bandwidth is worse than my NF2 system was

Ok still need some help with this. Here's where I'm at so far: (See Screenshot)

I don't have an Expert, but I think you need to refresh your A64Tweaker.

Those timings HAVE to be wrong..

[Ub3r-L33ch]

hah, yeah, didnt notice. I'll get another one up in a sec.

Ok this is what I got now, seems to be stable. Using 3.09 Volts on RAM.

Hmm what mhz on the ram?

This is what i get when i test fast. This is old bh5, no utt stuff or new bh5.

Hmm.., adjust read preamble to 6ns, and try the following timings and see if it'll improve things

Vdimm: 3.4v
chipset: 1.7v

CPC: Disabled (doubt enabling this will work with 4x512)
Trcd: 2
Tras: 7
Trp: 2
Trc: 12\14 or 16
Trfc: 12\14 or 16
Trrd: 3
Twr: 3
Twtr: 2
Trtw: 3
Tref: 3120 or 3072
Bank Interleave: Enabled

Skew Control: Auto
Skew Value: 0\32\64\96\128\250 or 255
Drive Strength: try 1\4\6 and 8
Data Strength: 1\2\3 and if you have it 4
Async latency: 8\9 and 10ns
Dram Response time: Slow or Normal
Idle cycle limit: 128\256
Dynamic Counter: Disabled
32 byte granularity: Enabled\Disabled

If you havent already, flash to the latest expert BIOS or get bigtoes modded expert bios from HERE

Thanks for the help guys, I'll give these settings a try.

What exactly does the mod bios do? Help with OC at all? I was under the impression there's really nothing left to tweak with the Expert BIOS.

bump, what happened to this board being able to run 4x512 at 1t 200mhz.

I can't even run mine at 200mhz 2t with 4 sticks of redline i just had 3 hours ago at 250 3.3v on my sli-dr

From my Ultra-D I can get this... (3.4V full stable)



I use this spreadsheet to keep my settings, notice at the botton different performance for those kits at same CPU speed

That was one of the reasons for the release of the Venus.
