Why memory Frequency is so Slow ?

[Mir96TA]

I am not over clocking; however I do think memory I have should run lot faster.
It only running at 333Mhz with Ratio of 1:1
Here is pic of Mem Cpuz
CPU running at CPUz
What really bother me is Max Bandwidth
Is this Normal ? or running Little Slow ?
BTW I have Latest BIOS F5

333MHz is the Memory Bus frequency, for the DDR2 speed of 667MHz. (Double Data Rate 2).

Wouldn't Model from OCZ OCZP800R21G would run at DDR2 Speed of 800Mhz with Freq of 400Mhz with Ratio of 1:1 ?

Don't know what motherboard you have, but in order to raise the Memory Bus to 400MHz, you must set the memory divider to something like 1.2.

My FSB is 325MHz x Memory Divider of 16/13 = 400MHz x 2 DDR = 800MHz memory speed.

BTW, where do you see the bandwidth in the CPU-Z...?

Measure it with SANDRA or Everest.

Ratio 1:1 means the FSB of 333MHz : Memory Bus of 333MHz = 1 : 1.

Well I can run the memory with 5:6 Ratio Do not have 1.2 it will bump the Freq to 400 however then I am 333Mhz cause it is running at 400Mhz with 5:6 Ratio.

If you click on MAX Bandwith Pic you will see Row (second) indicate Max Bandwith info.

6:5 is 1.2, so you are fine.

If you increase your FSB speed to something like 350MHz, you must change your divider to 8:7 (if available) to keep your RAM running at 800MHz.

I think I didn't ask my Question very well.
I want to use memory at MAX Speed (800Mhz or some thing) at the Ratio of 1:1
is that possiable ?

If you want to use your memory at 800MHz, and you MUST (for some reason...) use the ratio of 1:1, you have to set your FSB to 400MHz.

But you have to realize that it will increase the speed of your CPU as well, unless you lower your CPU multiplier to 8 - then your CPU will run at 8 x 400 = 3.2GHz.

And this is a whole another issue...

Just use your Memory Divider of 6:5 with the FSB of 333MHz for now and the CPU multi of 9, and read all the posts regarding overclocking and dependency of all the components on the FSB frequency.

Once you've learned the basics of overclocking, you can try to accomplish your desired 800MHz with 1:1 ratio.

But believe me, stability is more important than the 1:1 ratio, so don't be afraid of using the Memory Divider. Even with the use of the divider you are using your RAM at MAX speed of 800MHz.

I also have the E6850 and PC2-6400 (DDR2-800) memory. I run stock and my memory is running at 800. I simply set my memory at "Auto" and it sets my memory divider automatically. Try changing from 1:1 to "Auto".

I understand what you saying
However I do not want to O.C. the FSB
I want to use the MAX Speed avaible off my RAM.
I would like to get MAX out before I would O.C. my Computer.

Yes. Use your 6:5 Memory Bus divider.

Some manufacturers program the SPD chip with the relaxed timings and lower initial frequency, to allow the boot at 1.8V.

That's why it is very often necessary to change the settings in BIOS manually, setting the Memory Frequency to ex. 800MHz, timings to ex. 4-4-4-12-2T and voltage to ex. 2.1V.

The "Auto" setting might result in RAM running at 1.8V and 5-5-5-15, or with the EPP in SPD 4-4-4-12 and 1T Command Rate, which might prevent some motherboards from booting altogether.

Yes, I understand what you are saying. My system sets the ram at 800 if I set my memory voltage at 2.2 and "Auto". It would be useful to know what kind of mobo the guy has. CPU-Z states my divider is 5:6 not 6:5.

Mir96TA,

So you have a Gigabyte board. Since I have a similar board, I think our bios would be very similar. Did you make any changes in your bios? If so, I'd go in and hit "Optimize Defaults" first to get back to good settings. Then I would change the voltage for your memory depending on what your memory should run at. Then I would change the memory timings to the timings that your memory can run at.

After all that, you should check to see what your memory is running at. You should find that it will be running at 800 if your memory works the same as mine. If this doesn't work, then we will need to give you plan B. =;c)

Yes I have Tried
It didn't worked out for me. Mobo will not make MEM Freq go 400 with 1:1 Ratio.
Only time it would goto 400 Mhz if would set timing multipler for Auto then it would pick
5:6 Ratio then it would run at 400 Mhz
Other wise it would run 333Mhz with 1:1 Ratio.
I think JEDEC programing is holding my Mobo back; Since I do not have Freq selection
so it would pick what ever it can from JEDEC :|

You obviously just aren't good with a calculator. 333 Mhz FSB x the 2.4x memory multiplier = 400 Mhz RAM speed, or 800 DDR2.

It worked the way it is supposed to work. You can't run your memory at 800 with 1:1 divider when your FSB is set to 333. You need to use the divider to run the memory at 800 when your FSB is set to 333. So when you set to "Auto", you are allowing the mobo to set the memory divider to 5:6 so you get your memory to run at 800. For the Gigabyte board you could get the same divider by setting it to 2.4X like myocardia said instead of setting to "Auto".

So to sum it up, you can't run (nobody can) run the memory at 1:1 and get 800 when the FSB is set to 333. If you want to run your memory at 800 you can either select "Auto" so the mobo automatically sets your memory divider or you can manually set the memory divider to 2.4X which is a 5:6 divider. Do you understand?

By the way, what kind of memory do you have?

I didn't knew Bus speed and Rated FSB are not some thing.
I alway thought FSB is the Bus speed (Clock in Htz) between Memory and Cpu.
I think there is a divider between Bus and Rated FSB

 

[Ozoneman]

Your FSB of you cpu is 333. If you set at 1:1 you get 333:333(times2) because the ram is DDR2. So 1:1 then becomes 333:667. Your ram can't run at 800 with a FSB at 333 and your divider set at 1:1. Do you understand what I'm saying?

Like I said before, you need to not run at 1:1 and set your memory to "Auto" or 2.4X. This is the only way you can get your memory to 800 without increasing your FSB.

You also need to set that OCZ memory to 2.1 volts and the timings to 4,4,4,15 if you don't already have them set.

 

[jonmcc33]

There's no improvement from running your memory higher than your FSB. Either overclock your FSB or run the memory in sync with the FSB.

 

[Regalk]

To OP
Remember to press Ctrl+F1 when in Bios to see hidden timings
You have to change your memory divider from Auto (or 2.00) to 2.40 (333 X 2.4 = 400) or 5:6 if this is what your bios tells you
Change memory voltage and timings to OCZs specs i.e. MANUAL timings - default + .03 and timings at 4 4 4 15 or something like that depending on OCZ's
You have to do this since there is not other way of running at 333 FSB and mem at 400 and move on ..

To jonmcc33
"There's no improvement from running your memory higher than your FSB. Either overclock your FSB or run the memory in sync with the FSB."

You can support this comment I suppose since I have tried several settings and can show that running mem faster does improve things somewhat
I am at 400 X 8; mem at 2.5 = 1000 and that has given me extra fps in several benchies. It would be nice if I could run at say at 460 X 7 with mem at 920 but the GA P35 D3SL will not run beyond 416FSB with the E2160.

I see you are giving incorrect information again. You really need to stop giving advice. You may be doing more harm than good.
