Hi i have the Asus P5W DH intel E6600 and corsair RAM ddr2-800 with 5-5-5-12 timings but I dont really get this part:

Quote:
**Expand options for Gigabyte BIOS under ‘M.I.T.’ by pressing CTRL+F1**
Gigabyte: Set ‘Memory Multiplier’ to 2 (1FSB:1RAM operation)
ASUS: Set ‘DRAM Frequency’ to DDR2-533 @266Mhz FSB (1FSB:1RAM operation)
As you increase the FSB, the RAM will follow in the pattern of 1:1 shown in BIOS.

1. Set ‘DRAM Timing’ to manual or disable SPD (use SPD for P5W DH)
2. In BIOS you will see 4 separate timing digits, change them to the ones specified on your RAM

e.g. 4-4-4-12
CAS# Latency (tCL)
RAS# to CAS# Delay (tRCD)
RAS# Precharge (tRP)
RAS# Precharge Delay or Active to Precharge (tRAS)

When 1FSB:1RAM is overclocked above the rated frequency of your RAM use the following values
Timing: 5-5-5-15
vDIMM: 2.2V

e.g. DDR2-667 4-4-4-12 1.9V operating at ~400Mhz will need to be set to 5-5-5-15 2.2V

3. Leave the rest of other timings either at ‘Auto’ or at their default values


so am I really supposed to set it at 533? and not 800? and so Ishould use SPD and not set the timings manualy?


I know its short notice but i could really use some help on this one...

alright I got it up to 3.0GHz but Im not sure if it is stable yet I will have to check tomrrow since its 4am here.... however the ram Im not sure that i did right... would really like some help with that.... and acording to my BIOS the temp now is 33C at no workload.... is that acceptable?

edit: oh and yeah I have a scythe mine and as5 compound if that helps determining if the temp is good

33C at no work is easily acceptable, though the temps that we really need are the temps after a few hours of Prime95 or other stress tests.

yeah Im gonna run all the test that wusy suggests tomorrow but now I need to sleep cause Im picking up another new computer tomorrow morning...

any RAM help?


goodnight

This looks to me like they just wanted to obtain a 1:1 ratio. Personally I think the extra RAM bandwidth of DDR2 800 will outperform the 1:1 equivalence, but I could be wrong.

What I have my E6600 at is 340Mhz x 4 = 1360Mhz FSB (x 9 CPU multiplier) and the ram at 906Mhz (4:3 ratio). Its been working fine for me.

Just keep in mind, when you have it at a 1:1 ratio it goes up with your FSB.. so make sure you have good enough ram to overclock that high.

Im no expert but what I think your suposed to do is leave the ratio at 1:1 so that you can up the FSB to around 400. That way your ram shouldnt be an issue as you can consetrate on the CPU to atleast 400 FSB. Mind you most ram can go higher than 400 with changes to the latency timings and voltages.

hope this helps

actually its a miracle that there is no smoke coming out of my machine I have no idea what Im doing...I mean I do as wusy says but If I cant find something in my bios I just skip it... and half the voltages are not set right cause it doesnt look right or doesn't have the same name as the guide... but its at 3.0GHz at least and windows loads in mare seconds... but still I would like the ram to be atleast stock speed.. cause now when I load it says DDR5300 but shouldn't it be DDR6400?

ok this I dont understand how do I know what is a 1:1 ratio
and could I set my Ram to 800 without just crashing the whole thing?

and back to the other question... why does it say that I have PC 5300 RAM when Its supposed to be PC 6400 right? it said so even before i started to overclock...

Not sure about that. What are you checking it with? I know some programs (Everest Home) will show something different then CPUz. If its the BIOS that is reporting PC 5300 then that means its RUNNING at 667Mhz (PC 5300).

There should be some option somewhere in the BIOS to change the ratio. i don't know how Gigabyte does it or where it would be in their BIOS, but Asus has it where you change the clock of the CPU.

I will try to explain better when I get back from class. I apologize if I am not clear, I really suck at explaining things.

alright cool, thanks so then I can stop worrying about the ram... but so should it run at pc5300 or 6400? or am I supposed to slow it down because Im oc'ing the cpu?

and then there is the matter of voltages... I dont know what to do here I just cant find some of the voltage settings that wusy talks about and some that I change turns red when I change them to the settings wusy suggests. is that normal?
