Memory Timings Explained W/ Suggested Timings & Memset VS. BIOS

Re: Memory Timings Explained W/ Suggested Timings & Memset VS. BIOS

Ahh yes, you are correct. I was thinking of the other write to read/read to write settings.

You will not be able to set these with current GA BIOS, you could write in and make a suggestion for them to add it when they have time.

They are always improving BIOS and would always love to hear what customers need, shoot them an email and ask them to pass along the suggestion to the BIOS engineers

No such or similar timings in advanced and channel a/b settings, in DFI mobos you can directly change them, in GB maybe some other timings affect them.

Re: Memory Timings Explained W/ Suggested Timings & Memset VS. BIOS

I will check for you tonight, did you look in the advanced timing, and turnaround pages?

Re: Memory Timings Explained W/ Suggested Timings & Memset VS. BIOS

I've always wanted to ask is there way to set up all precharge to activate and all precharge to refresh timings on Gigabyte boards (UD series to be more specific). Are they dependant on other timings?

Re: Memory Timings Explained W/ Suggested Timings & Memset VS. BIOS

I need some advice as regards my timings please. My trd shows as 1, is that possible? I had timings at 7-7-7-16 and it was 2.

Had seen another user that hade the same.
Can you boot if you set it manually to 1?

Thanks for this thread Lsdmeasap, very interesting.

I need some advice as regards my timings please. My trd shows as 1, is that possible? I had timings at 7-7-7-16 and it was 2. Have them at 6-6-6-16 now in bios, all other ram settings are on auto. Thanks for your help.

Re: Memory Timings Explained W/ Suggested Timings & Memset VS. BIOS

i just have 1 stick of ram now, and the other stick ill add when i get home is identical :)
well im off home now.
have a nice week-end and 10x again

Re: Memory Timings Explained W/ Suggested Timings & Memset VS. BIOS

It's not realy a problem just what this CPU is capable of.
If you get new ram stick try to find the same model you currently have. Mixing different ram may also be a problem.

Re: Memory Timings Explained W/ Suggested Timings & Memset VS. BIOS

yeah ur right, i wont try it :)
maybe ill get a new cpu, that should solve the problem :)

[Chike]

Re: Memory Timings Explained W/ Suggested Timings & Memset VS. BIOS

No chance for that, better not even try. If you could control CPU ration than maybe.

Re: Memory Timings Explained W/ Suggested Timings & Memset VS. BIOS

No CPU Clock Ratio or Fine Clock Ratio.
and yes, the multiplier is 23
ill try with the fsb at 200, hope it will stay stable :)
any other things i should change, voltages or smth?or should i leave everything on auto?

LE: come to think of it...if i up the fsb to 200, ill get like 4.60ghz cpu speed

Re: Memory Timings Explained W/ Suggested Timings & Memset VS. BIOS

No CPU Clock Ratio or Fine Clock Ratio in BIOS?
Yes, CPU multiplier is 23 I think so it would go over 4.6GHz.
As I said I don't know about that CPU, maybe someone else does.
Upgrade maybe, E6x00 or E5x00 if you don't want to spend too much money.

Re: Memory Timings Explained W/ Suggested Timings & Memset VS. BIOS

well i was kinda thinking that the CPU would be the downside, since is way past his bedtime :).
i do not have the "cpu ratio" option in the bios screen, i can only increase the fsb but this way the clock speed will go up to right?
any suggetions?
thank you

hi
i have the following mother board ga ep-31 ds3l rev 2.1 motherboard with FC bios
i would like some help in setting the timings for my ram, everything is set on auto in bios. i got 1gb ddr2@800 mhz 5-5-5-18 kingmax(gonna add another 1gb stick this weekend for 2gb)
thing is that the mem is seen at 533mhz 4-4-4-12 with everthing on auto and its voltage is 1.936, i want to know what to do to make it run at 800mhz, its default speed.
im running an Intel Celeron D [email protected], hd 4650 512ddr2/128 bit
if you could help me with all the settings(and i mean everything :D), since i dont know anything about this stuff :)

The CPU bus frequency 133MHz and max memory multiplier 4 are limited to DDR-533.
The only way to get the memory running at 800MHz is to OC bus speed to 200MHz with CPU Ratio 15 or 16, which I don't know if it is possible with this processor.

p.s. bad thing is that i dont have internet at home untill after newyears, and i can only check this when im at work

ill add this to if it helps, hope i did it right(where i put an "X" means i dont have that option):
