Can't change CAS Latency?

Hi all,

this is my first post and I'm quite new to this sort of stuff so sorry if my question sounds stupid!

My machine spec;

Machine : Dell Dimension 9100
Mainboard : Dell 0X8582
Chipset : Intel i945P
Processor : Intel Pentium 4 640 @ 3200 MHz
Memory : GeIL 2GB (2x1GB) PC6400C4 800MHz
Video Card : Nvidia GeForce 6800

I have just bought the 2GB Geil kit and need to set it at the correct settings of 4-4-4-12.

The problem is that I cannot change this in the Dell BIOS as it is very limited.

I have downloaded Memset and I managed to change the settings to 5-4-4-12,
but the CAS Latency won't budge from 5 to 4! Does anyone know a reason for this?
Are there any other freeware apps that I could use to alter the timings etc?

My other question is that my fsb/dram ratio is 3:5, therefore the CPU is the bottleneck?
(Correct me if I'm wrong) What is the best way to alter my settings to give me a 1:1 ratio??

Any help is greatly appreciated!

Cheers,

Chris.

Thanks a lot for the reply Steve 258,

There was an option in the BIOS that allows you to change wether memory changes can occur or not. But it was set to allow me to make changes.

The strange thing is that Memset allowed me to change the other three settings but not the CAS?

So a few more questions:

1. Is there anyway of checking/changing my Voltage without going into the BIOS?

2. Can you change the BIOS of a Motherboard?

3. Are there any other programs apart from Memset that can be used to alter CAS timings?

4. What would I have to change to get a ratio of 1:1?


Cheers,

Chris
 
Thankyou for your reply Flanno. I'm glad you've cleared that up. I just wanted an answer either way to save me from scouring through more sites!

Do you think buying this RAM was a waste then?

I was running 2 x 512Mb PC2-3200 before I bought the Geil set.

I did do some research before buying the set and knew that PC2 6400 was compatible with my motherboard which is why I bought it, but now I'm a bit unsure??


Thanks again,

Chris.
 
OK, thanks for the reassurance Steve,

but considering the Geil RAM is not running at a 1:1 ratio, could this be running slower or the same as the original 1Gig RAM, therefore pointless?

I know I can use it for future upgrades but should I put my original RAM back in and keep hold of the Geil for something more appropriate in the future?, or leave it in?

Could I run the 2x512 PC2-3200 alongside the 2x1Gig PC2-6400, and then have 3Gig running at the lower speed of PC2-3200?? (I know you aren't supposed to mix and match in most cases)

Thanks for your patience everyone.

Thanks a lot

Chris
 
Thanks Flanno,

In an earlier post from Steve, he said that my fsb is 200mHz? I think he worked it out from my fsb/dram ratio of 3:5

So if it is a 200mHz fsb, should I stick the old RAM back in along side it and run it all at 400mHz (200mHz)?

I take it its's better to have your RAM run faster than the FSB than the other way around?

Thanks,

Chris
 
Sorry Steve, wrote my reply before you wrote yours. That ratio guide helped and confirmed my fsb IS 200mHz so thanks for that, but the same question applies, is it better to better to have your RAM run faster than the FSB than the other way around?

So would it be worth running all 3Gig at the same speed (400Mhz/200Mhz)

Or stick with the Geil 2Gig running at 667mhz/333mhz

Thanks a lot for your help
