Discovery About "Stuttering" and Laggin Video Card

well i wrote the story but i submitted the new thread and it didnt post, bhaa :moon: , it had some error within the fourm

"Stuttering" "Lagging"

There is TRAS which can cause to Data Corruption if u set it too low, its a memory option as u all might know. so try to up it from 5 to 8 or to 10, 10 works best for Amd64 754 Nforce 3

i dunno about nforce 4 or intel.

but if u have those symptoms try that.

If u have Amd try to use A64Tweaker to easily change it from windows, or Ntune if its there

 

Hmm ... really ???? does it actually remove some stuttering ??

*UPDATE* ... strange .. i'm getting a better mem. bandwidth result with it set to 8 from 6 .... about a solid 40 MBps increase ... will test some particular games and return ....

 

usually for A64 systems 10 works best, and 0 in DFI boards performs the best

 

i had it set to 8 , just changed it to 10 in the bios and , the Software sandra Memory bandwidth test has increased for 80%-82%

is this good or should it be higher??

 

no, 00 is not good, u are killing the mem, its overkill as the same for every mem that u put TRAS over 11.

TRAS is the min time for the data to complete its order by cycles, if u set it too low the data just dont tranfer and thats why u have freezing, too much power with too fast time is overkill, the main problems comes from memory.

 

A longer time settings like a tras 10 or an 11 makes good sense for the dual channel setups this was discovered back in the nforce 2 days

 

so if i got DFI Lanparty Ultra-D Nforce 3 mobo, which setting should i use?

AMD 3200+
Mushkin Blueline 2,3,3,5 ( 512x2 MB 2ch )
6800 GT

 

Yeah will setting my board to TAS10 work better for my Nforce2 then?

 

I change the tras setting to 10, and then I run TR:Legend with NextGen on.. It feel a little smooth and playable... thanks

 

lol... no, 0 just means to make the board calculate de best TRAS setting
I dunno, it works perfectly fine with the NF4/DFI mobos

I can show you a screenshot if you REALLLLLLLLYYYYY need one...

 

0 ??? maybe it reverts to the default while booting ... check using Everest ...

 

"Min RAS# Active Timing(tRAS)

This is the fourth timing that most ram companies rate there ram with. For example, you might see ram rated at 3-4-4-8 @275mhz. this is the 8, in that situation.

From Adrian Wong’s site: http://www.rojakpot.com/
”This BIOS feature controls the memory bank's minimum row active time (tRAS). This constitutes the time when a row is activated until the time the same row can be deactivated. If the tRAS period is too long, it can reduce performance by unnecessarily delaying the deactivation of active rows. Reducing the tRAS period allows the active row to be deactivated earlier. However, if the tRAS period is too short, there may not be enough time to complete a burst transfer. This reduces performance and data may be lost or corrupted. For optimal performance, use the lowest value you can. Usually, this should be CAS latency + tRCD + 2 clock cycles. For example, if you set the CAS latency to 2 clock cycles and the tRCD to 3 clock cycles, the optimum tRAS value would be 7 clock cycles. But if you start getting memory errors or system crashes, increase the tRAS value one clock cycle at a time until your system becomes stable.”

It appears throughout the web that this is a much debated timing. Some may argue that 00, 05, or 10 is the faster/most stable. There probably isn’t a right answer for this one, it all depends on your ram. If you need a good starting point, usually most/all ram can achieve their max OC on 10 tRAS, even if one of the other settings is faster.

Dracula has a nice little table here:

VALUE MEMORY: CAS + tRCD + (3 or 4) = tRAS

STANDARD MEMORY: CAS + tRCD + 2 = tRAS

EXTREME MEMORY: CAS + tRCD + 1.5 = tRAS

FLAG-SHIP MEMORY: CAS + tRCD + (05. or 1) = tRAS

tRC = tRP + tRAS


Slight Influence on Bandwidth/Stability.

Suggested Settings for DFI NF4: Suggest you use only 00, and 5-10. I’d start with 8 and play around from there. (Lower = Faster)"

More HERE i found it very useful

 

Yes i searched google about it and believe me from experiance i tried everything, and trust me, no one want to have Data Corruption because of one singel Memory Setting.

the lowest is only good if u have good mem and u dont OC

 

um, the mobo actually calculates the best Tras setting needed for my setup when set to 00...

I said it before...

 

there is no 0 setting for tRas in the BIOS for my DFi Lanparty UT Ultra-D Nforce 3 mobo

 

if you have read I said DFI+nf4 mobo

"lol... no, 0 just means to make the board calculate de best TRAS setting
I dunno, it works perfectly fine with the NF4/DFI mobos"

 

so, is it auto?

 

AUTO reads the SPD in the ram

 

It's better to avoid SPD reading if you can. My OCZ RAM reports 2.5-3-2-5 in the SPD, even though it is rated 2-3-2-5. From this thread, I assume that although TRAS 10 might be good, I should probably stick with 5 for my RAM, yah?

 

They're other tricks, like using "Large Cache" in Windows
or a memory Burst lenght of 16 instead of 8.
