New build not 3-4-3-9 T1 Ram timings

Hello,

 

I need help setting my system ram at desired 3-4-3-9 T1 timings stated on the ram.

My bios set the ram as 1.8 volt 5-5-5-18!

I can manually change all these settings but not to 3-4-3-9; it will not boot.

 

Thank you.

I doubt if you are going to make high speeds or tight timings with Phenom boards and CPUs.

 

They are known to be very wonky at high end values.

If I were to use 2gb sticks for ddr2 1066 speeds would they be set at 5-5-5-15 for Phenoms?

Can Phenoms run at 5-5-5-15 ddr2 1066 with 1gb sticks?

 

I am unable to set CAS below 5 with Memset.

 

I might try bios change to CAS 4. Command Rate T1 will lock up under Windows after a bit.

Overall better than 5-5-5-18-22 default. :sunglasse

PC froze.

I am using JEDEC now at 5-5-5-15-22 to see if it will freeze too.

Memtest showed no errors for both.

3,4,3,9, RAM may require 2.4v as stated on my DOM DDR800 RAM. im running mine at 2.25v but cant clock too high.

could just be voltage.

also FWIW i could never get an AMD system to run @1t only 2t.

Runs stable at 4-4-4-12-22 2T with upping the voltage!

How much can this be lowered from 2.4 volts still running stable?

I'm not sure if messing with it now is worth the hassle. :nono:

i started at 2.35 and lowered it .05 until it got funky at 2.2 so at 2.25 it seems golden.

i hope you have the cool Corsair fan blowing on them!!

they will blow at 2.4v with no fan!

whats your 1M SuperPI?

30.732s at 1m.

I am not using the fan because i thought it may fall off. I may have to use it to prevent blowing my ram.

My case temperature is at 9 celcius with out the fan for the ram.

Thanks!

30.669s @ 2.27 volts.

1.8 volt 5-5-5-18-22 I get errors.

and 5-5-5-15-22.

I would set 1066 and 5-5-5-18 with 2.1v with that board and CPU. Then when you move to Intel you can begin to use the DRAM in higher values. You can very easily damage the DRAM attempting to access the extended frequencies and timings on that system.

 

Your choice though.

I will upgrade to 2gbx2 1066 and run the same timings as this 1gbx2 800.

 

How can 1066 run at the same settings as JEDEC for 800 with the same board. Up the voltage before the ram frys itself?

No point in bothering with 3-4-3-9 unless it's at 2.4 volts but everyone says they will blow unless I use the three little fans on top. I have 2x140mm fans above them already with 9 degrees celcius case temperature.:confused:

 

Maybe a different board could run the EPP on these 800 chips.

having the Corsair fan is much better than airflow from further away unless your 140s are a high CFM. the 3 fan unit is designed for more airflow over the tines on the top of the RAM thus cooling more efficiently. thats all im saying:)

I am using the Dominator fans.

At ~2.4 volts it will boot with 3-4-3-9-22 CR T2. However once in Windows it restarts by itself.

 

I wonder about the voltage of my other ram; DDR1 400 2-3-2-5. It's voltage runs ~2.70! No fan. It has no problems, why does 2.4 on this newer ram (Dominator) with a massive heatsink have issues with .3 less volts?

Stable as of yet. Playing Warcraft3 Frozen Throne without hiccuping or freezing.

 

I don't agree with 2.4 volts at these clocks. What is a good voltage for them now? 2.1 volts? I will mess with them until it freezes, restarts or has errors.

SuperPi mod will still say errors and not respond but I can play games?

SuperPi mod had errors at 5-5-5-18-22 CR T2 1.8 Volt.:confused:

 

Thanks!:D:

 

Much slower than Synthohol.

Much slower than Synthohol.

 

Of course it is. You have an AMD and they ARE MUCH slower than Intel.

5-5-5-18-23 CR T2 ~2.37 volts I got ddr2 800 up to 1360 stable.

Lowered ht to 800 and cpu multiplier to 10.

I might have higher clock speeds with x2 64 6000+ 89 watt versus 5600+ 89 watt.

 

New OC.

I was able to tighten timings to 4-4-4-12-22 CR T2 and max at 234 fsb!

This will be my best OC so far.

For your AMD system, that's quite a good clocking, both on the CPU/DRAM but also superpi.

My Foxconn A7DA-S can max voltage at +6 whatever. It reads 2.352 under the BIOS. So, I can OC with relaxed settings 5-5-5-15-22 at 2.352 volts and get 1360 for ddr2 800 ram or use 4-4-4-12-22 with 2.1 volts and under? Even CAS4 will OC around 1000.

 

I'm hoping to get another motherboard that can run 2.4 volts. If I do I'll post my results. Might get 1T CR too!

My advice?

 

Sell that AMD board and cpu. Buy a Core 2 E5200 and a P5K motherboard. Clock that puppy up to 3.4 - 3.6Ghz.

 

Then you will see what speed really is, and it's cheap. Ramp that DRAM up to it's true speed and have a machine that can really use it.

 

E5200 =$82.99

P5K-E Pro =84.99
