Help with RAM settings.

[de8212]

As a spinoff to another thread of mine here, i was curious to set my RAM a little higher.

First of all the RAM is Kingston HyperX RAM

Here are my choices, one entering the Advanced BIOS settings.

CAS Latency Time 2, 2.5
Active to Precharge Delay 5,6,7,8,9,10
DRAM RAS# to CAS# Delay 2,3,4
DRAM RAS# to Precharge 2,3,4
Refresh Mode Select 7.8us, 15.6us, 64us

Bold indocates current/default settings.

SO, any ideas on where to start?



BTW I know I have seen this before but the AGP aperture size is set @ 128MB. IS this the best settings even though I have a 256MB vid card or is this not the same???

Thanks for any help.

Well, that HyperX should be able to run CAS 2, so you should switch the CAS to 2, then do some stability testing.

if your overclocking you might wanna loosen it up a bit 2.5,3,3,8

Not overclocking at all.

I take it the lower, the "better"????
So could I just do 2,5,2,2, 7.8?

The ram can't do those speeds. Just lower them to what kingston says the ram can do on their site.

ya know what if you jsut simply use AUTO it will use the best timings for the ram.........

and use 256 AGP Aperture for a 256meg card. if someone argues with that then they have no clue what they are doing.

Sometimes the auto timings are a little looser than the RAM supports. My auto setting were 3-4-4-12, though I am now running 2.5-3-3-10 easily.

Also, about aperature sze. that is just how much system RAM the graphics card is alowed to use if it runs out of video memory, right? I thought you should set it to be around half your total RAM size. I am not claiming to know anything, I was just curious why.

I understand that but then why not just use the "auto" settings for you cpu, video card, etc.?

I just wanted to bump it up a bit but the settings look different then my old epox mobo/crucial RAM combo.
