Is it better to let the bios set the timings in automatically or tweak them manually?? Currently my setup is in automatically at 2.5-3-3-7 (cas-trcd-trp-tras) I have 2100 ddr memory currently in the computer. Not oc'd. Would there be an advantage to tweakin them or just leaving them alone.

If the RAM can handle it, tightening the timings can result in better performance due to reduced latency. I'm not a big RAM expert so I am not 100% sure on the optimum for each setting but this may help: http://www.ocforums.com/showthread.php?t=257741

This is the OC Forums. Tweak them in maually of coarse. Give us some specs on your system. i.e. Memory Manufacturer, CPU, mobo. First try dropping your CAS to 2. and test it for stability.

why not tweak it if it is possible? you never know till you try, if you lower the timings you will lower your ram latency so there is an advantage... although minute and probably unnoticable, but be ready to reset the cmos if the ram can't handle the timings, you could most likely lower the tras no problem, as for the other timings just try it out

I have 768 mb (ddr 2100) of memory (two sticks) 256 unbranded memory 512 kingston. The computer is a home built. The Cpu is an amd 2600+ fsb 133. I have a Ga-7dxr. Oh ya btw I have my cas now at 2 so my current specs are 2-3-3-7. I will prob try changing the tras later just trying one thing at a time. But as of right now is seems to be working very good.

Thats pretty good for that particular memory.

Yeah, you should do it manually, if you can. Read that guide that David posted.

I read it but most of the stuff the read is a little more advanced then I am so I will have to read it a few times to understand it. Changing that from 2.5 to 2 seemed to speed it speed things up some. I might try tweaking some of the other numbers maybe unsure if I want to though. Mostly becasue I dont want to have to use the jumper.

Yup dual bios works LOL. I changed my timings to 2-3-3-5 and the other bios kicked in. Well I guess I cant go to that setting LOL I have it at 2-2-2-6.
