Tweaking my memory

Here are my BIOS ram timings... it's running in dual channel and 2T. My board doesn't have an option to set ram to 1T.

CAS Latency Time________________ 5
Dram RAS# to CAS# Delay_________ 5
Dram RAS# Precharge Delay_______5
Precharge Delay (tRAS)__________ 15

ACT to ACT Delay (tRRD)_________ 3
Rank Write to READ Delay________ 3
Write to Precharge Delay_________ 3
Refresh to ACT Delay______________ 42
Read to Precharge Delay__________ 3
Static tRead Value_______________6
Static tRead Phase Adjust________ [Auto].... default is 25 (I think?)



I've tried 4-4-4-12 and it failed. I was thinking of trying 5-5-5-12... would this help?

What about the other settings? Lowering the numbers would mean the system is getting faster, right?
 
What brand & model of each type of RAM are you running? I see 6gb in your sig, so that means 2x2gb + 2x1gb.

You can't run 1T on intel chipsets. It only works on nvidia chipsets and even then, typically with only 2 slots filled max. Don't worry as the hype around 1T is vastly overrated.

At 480x7, you're going to be hard pressed to run 4-4-4-12 @ 1:1 even with 2.2v, which will destroy your RAM if it's run 24/7.

Frankly, I'd be satisfied with 5-5-5-15 timings at 480mhz with all 4 slots filled. Tightening tRAS further to 12 isn't going to have a significant impact.

Btw, I'm in the same situation as you. I have 3gb (2x1gb + 2x512) and am running 480mhz on a 2:3 divider (320 CPU FSB: 480 RAM) and have been down this road before. I cannot do 4-4-4-12 on my board with 4 slots filled at anything over ~ 425mhz with reasonable voltages (reasonable to me is <2.05v since I had 2 sticks fail already).

Running superpi, I have found that maxing ram speed at lets say 533mhz (3:5 divider in my situation) at looser 5-5-5-15 timings is better than 4-4-4-12 @ 400mhz -- try it yourself if you don't believe me. Unfortunately for you, you probably won't be able to run anything else but 1:1 considering that even a 5:6 divider in your case puts your RAM speed up to 576mhz which is probably out of the question at any reasonable voltage.
 
Review these benchmarks and then realize you're wasting your time fighting for tight timings or increased bandwidth (neither of which significantly affects real-world applications).

That's right. In fact, the type of processor and speed of RAM don't matter either!!!

Would you get off it Denithor, if he wants to improve his system, even a little bit, stop pooping on his party.

You may get better performance with just the GSkill at 5-5-5-15 around 1050 (or how ever high your dividers will let you run them). How high can they go with a lower FSB and higher divider?

Very true unless this OP actually needs and uses that last 2GB.
 
I "don't" need all that 2 gb of ram, but it was lying around collecting dust. Plus I like the feeling of 6 gigs of ram and knowing I have plenty with plenty of headroom.

The lowest divider is SPD at 2.5. With a that, the ram would be running at 1200.

😱 :roll: :laugh:

If you look over the benchmarks from the last two years, C2D likes bandwidth more than tight timings. So do what you can to push up that speed. Depending on the particular sticks you may be able to feed them some extra volts to get stable performance at higher speeds.

Enjoy your tweaking!
