FSB:RAM ratio on MSI KM4AM-V...CHANGE???

Hello.
I was wondering if anyone knows how to change the FBS:RAM ratio on this board.
It is currently 1:1 but i would like to change it to 10:9 if possible or anything close to that...
Thanks for any help.

You're probably right, but what could we do without these kind of problems? I mean, if everything would be fine and the computers work out all the time, what could we do? I think that our life without these little problems would be a messy for us! Boring it's the perfect word to express the way our lives would be.
So you could try changing the jumpers on the board overclocking the FSB of the processor because on the SETUP you cant see anything ralated to change FSB or memory frequences, so just do it, but by your own risk
Bye, and thanks for remebering me the meaning of life.

Ram ratio

first of all how do you change your ram ratio on msi 875p
and am i right in thinking that 1:1 is best for performance
my specs:
msi 875p neo fis2r
p4 2.6(533fsb)(changing to p4 3ghz 800fsb)
pc2700(ddr333)dane elec(changing to k'ston hyper x pc3700 )

If you have a P4C (800FSB) CPU, these are your available FSB:RAM clock ratios:
CPU=200 DRAM=532 gives FSB:RAM=3:4
CPU=200 DRAM=500 gives FSB:RAM=4:5
CPU=200 DRAM=400 gives FSB:RAM=1:1 -> AUTO default
CPU=200 DRAM=333 gives FSB:RAM=5:4 (865/875DRAM=320 MHz due to )
CPU=200 DRAM=266 gives FSB:RAM=3:2
As you change "Adjust CPU Bus Clock" from the 200 MHz default, your DRAM frequency also changes based on the corresponding FSB:RAM ratio.
If you have a P4B (533FSB) CPU, these are your available FSB:RAM clock ratios:
CPU=133 DRAM=354 gives FSB:RAM=3:4
CPU=133 DRAM=333 gives FSB:RAM=4:5 -> AUTO default
CPU=133 DRAM=266 gives FSB:RAM=1:1
If you have a P4A (400FSB) CPU, these are your available FSB:RAM clock ratios:
CPU=100 DRAM=266 gives FSB:RAM=3:4 -> AUTO default
BTW - on my system with a P4 1.8A , I have the ff. options available with BIOS 1.6 up to 1.8 beta:
DRAM Frequency = 266, 333, Auto, 354
But with DDR400 installed , I can't get it to boot with DRAM=333 or 354 settings.

MOVED: MSI P31 Neo and FSB/DDR ratio

This topic has been moved to Overclockers & Modding Corner.
https://forum-en.msi.com/index.php?topic=116635.0

Hello Aacko,
the P31 Neo is a budget board that is not really designed for overclocking (notice the red PCB). The P31 chipset supports DDR2-667 and DDR2-800 memory modules. With a FSB-200-MHZ-CPU installed, 1:1.66 and 1:2 are exactly the ratios you need to get your RAM to 667 MHz or 800 MHz.
Quote
Can I do something about this or should I swap P31 Neo to some P35-chipset mobo that would allow more flexible FSB/DDR ratio settings?
If you really want to overclock, you should go for a P35 Platinum or P35 Neo2-FR/FIR board.

P43-C51: How to optimize FSB/RAM bus clock ratio

Hi there, is there any way I would be able achieve maximum supported bus throughput of my RAM (DDR3-1600, Bus Clock 800MHz).
Currently I am only able to reach a RAM bus clock of 532MHz with my Dual-Core E6300 2.8GHz at 266MHz FSB using the BIOSs 1:2 FSB/DRAM ratio. I tried using the motherboards on-board OC switch to increase FBS from 266 to 333MHz, but the system won't even boot. With manual FSB adjustment I managed to increase to a stable 300MHz, though this didn't increase the RAM bus clock by much (only to 600MHz, still 200 off of my target).
If the BIOS would support a 1:3 ratio I would not even have to OC as this would give me a desired 266:800 FSB:DRAM ratio. The BIOS gives only a max ratio of 1:2, and as I'm not quite sure how the motherboard or CPU inter-handle the clock values I guess this max ratio is probably there for a reason.
I also speculated that If I could decrease the CPUs Bus/Core ratio from 10.5 to 7 giving me a FSB of 400MHz instead of 266MHz, and if I were to use the FSB:DRAM 1:2 ratio I could get my target RAM bus speed. Unfortunately I have not found a way to modify this on the BIOS.
Many thanks for any suggestions.

The 1:2 Ratio is the maximum ratio supported by the chipset. This is a hardware limitation, not a BIOS issue.
Thanks for the clarification.

Not even after a CMOS-Clear?
I did clear CMOS severel times after manually adjusting FSB when I was unable to enter back into BIOS, but I'm not sure If I tried the on-board OC straight after a CMOS clear. Or did you mean clearing CMOS after setting the on-board OC?
Will try both when I get back home. Thanks for the tip.

MSI P31 Neo and FSB/DDR ratio

I purchased P31 Neo -mb and E2160 processor.
I've red that this processor could easily hit 3.0 Ghz with 333 mhz fsb. The problem is that I can't find a setting from P31 Neo's bios that would allow to unlock FSB/DDR ratio. There is only Auto, 1:1.66 and 1:2 setting for FSB/DDR ratio. When I raise the FSB the DDR speed quickly raises over 800 Mhz and the system doesn't post. 2160 Mhz is the top that i've managed to overclock E2160 because my DDR2-chips can't handle the higher FSB speeds.
Can I do something about this or should I swap P31 Neo to some P35-chipset mobo that would allow more flexible FSB/DDR ratio settings?

Fsb/dram ratio on p31 neo

hi,
i have p31 neo board. in bios the only option for fsb/dram ratio is 1.1.66 and 1.2. with this option overclock is almost imposible (fsb <240)
a bios update will resolve problem or i can't do anithing.
thanks

Actually, the system should start even with DDR2-1066 memory installed, but it should recognize it as DDR2-800. You will not have additional memory dividers when inserting DDR2-1066 RAM. You even be able to increase memory speed beyond DDR2-800 MHz by increasing FSB Clock Speed. However, there is no guarantee that you can successfully make your RAM operate its rated speed.
If you are really planning to overclock your system, you may be better of looking for a board that is more up to this task (P35 Neo2/P35 Platinum would be a much better choice in this case.)

P31 Neo-F - I don't have 1:1 FSB\memory ratio

Corsair 6400XMS2 2 x 1Gb (Dimm1 & Dimm3)
Core2Duo 4300
Core2Duo 6300
The BIOS sees both sticks of RAM. I have tried slots 2 & 4 in desperation as well.
I can not get 1:1 memory ratio.
With the 4300 I get AUTO\1:1.66\1:2. Set to Auto it runs at 1:1.6
With the 6300 I get AUTO\1:1.25\1:1.5 (if my memory servers me right). Set to Auto it runs at 1:1.25
I have cleared the BIOS many times. What am I doing wrong?

The Corsair memory is DDR2-800 isn't it?

Yes, and there should be no problem making your RAM operate @800 Mhz by choosing the proper FSB/DRAM ratio in BIOS.

My MSI P35 Plat runs with the same memory at 1:1 fine with the same processor. So are you saying the P31 can not do the same?
I know, this matter is complicated, but I will try to explain and to give you at least a partial answer. P31 and P35 chipsets do not use the same memory controllers. Have a look at the Intel Datasheets for both memory controllers:
P31 / 82P31 Memory Controller Hub (MCH) --> DATASHEET
Page 21:
Quote
Supports Front Side Bus (FSB) at the following Frequency Ranges: - 800/1066 (200/266MHz)
and Page 25:
Quote
Differential Host clock of 200/266 MHz (HCLKP/HCLKN). Supports transfer rates of
800/1066 MT/s.
Compare to:
P35 / 82P35 Memory Controller Hub (MCH) --> DATASHEET

Quote

and Page 31:

As you can see, according to Intel specs, the P31 chipset itseld does not offer native support for CPUs that operate @333 (1333) MHz FSB Clock Speed. That is why, from a chipset point of view, the number and variety of possible dividers is less compared to the P35 chipset. Looking at the differential between FSB and Memory Clock speed you can also see that 1:1.25/1.1.5 (E4300) and 1:1.66/1:2 (E6300) are the native chipset ratios to match DDR2-667 and DDR2-800 RAM with FSB/200 MHz and FSB/266 MHz processors.
Of course, in practice chipset limitations can be exceeded by BIOS programming to a certain degree. That is why P31 boards actually do support FSB/333 MHz CPUs, but the support is not native. Have a look >>here<< as well.
The only situation in which you actually need the 1:1 memory divider is overclocking, but since this a budget board not meant to be put to excessive OC use, BIOS implementation of memory dividers that go beyond Intel specs is limited. After all, it is a matter of price/performance. The MSI P31 Neo-F matches the Intel specs and exceeds them when it comes to FSB/333 MHz processors, there is no real mistake here. I can find nothing in the Intel specs nor in the MSI Product information that says there has to be a 1:1 ratio implemented at all costs.
There is a chance, of course, that MSI will implement more memory dividers in a future BIOS release. Try contacting MSI, maybe they can give you a more definate answer this one:

The Intel chipset is capable of offering 1:1
Capable: yes, native support: no.

The issue is MSIs implementation of it = BIOS.
You are most likely right about BIOS implementation in general, but I don't see a reason to call it an issue at this point.

DDR3 RAM specification for MSI Z77A-GD65

Hello MSIers ,
I am about to buy the MSI Z77A-GD65 or GD55 not sure yet ... I used Gigabyte boards for 10 years and they always state to use 1.5 volt RAM sticks ...
Now for MSI and the mention board , what voltage should I pick ? I want 2 sticks of 4GB DDR3 1600MHz and might look to faster frequencies like 2333 MHz ??? will it work with an I7 3770 right out the box (if I load XMP in BIOS) ? can lower latencies or CAS as well ?
Thanks

Allot of the mushkin comes pre-under-timed (the xmp profile does anway) As that computer is an AMD platform, I need to match the xmp profile and adjust the fsb/ dram ratio to get the correct speed & timings. Both of those listed computers are quite stable.
The corsair memory I have listed has an xmp profile of 11-11-11-30, I manually under-timed that when I was tweaking. That is the lowest I could go and maintain stability.
One thing to keep in mind when you look at memory, is that almost all that you see out there is 1333 memory which has been tested and tuned (Overclocked) to w/er limit. Even ddr3-1600 you buy will by default run at 1333 as the 1600 is an XMP profile extension to the SPD. So no matter what you buy over 1333, you are most likely going to need to at minimum enable the xmp profile or at worst tinker with the speed & timings manually.
Nice .. Thank you ..
So what DDR3 freq. / timings you suggest for the best performance and stil very stable (as long as I (most likely) need to tinker a bit around the BIOS and XMP) ? I am gonna use the I7 3770 locked version CPU
You advice or against , maybe 2000 freq or more DDR3 with the Z77AGD65 ? or you advice with choosing a lower latency modules but at 1600 MHz freq like this http://www.mushkin.com/Memory/Redline/997056.aspx ?

FSB:DDR ratio?

I don't really understand the FSB:DDR ratio? I have a MS-6758 LSR with a P4 2.6HT . I have 1 gb of Crucial TEch DDR Ram. I downclocked my FSB back to normal because of an instable system in windows ( freeze all the time).
Can you help me finding the best settings ( FSB, DDR CLocks, AGP VOLTAGE ect..)
Thanks very much !!!!

You don't really 'lock' it to 400. You set it to 400 which puts it in 1:1 synch with the FSB at 200. I think what you want to do is set the DRAM clock at 333, so as it steps up with the FSB it won't reach 400 until your CPU is at a higher speed.
If you get this working, please report your current benchmark and your new benchmark when not running 1:1. I'm cursios to see the net effect of increasing your CPU speed while sacrificing memory speed.

Setting FSB:DDR ratio?

How does one go about setting the FSB:DDR ratio on the Neo-2 (865)?
I'm trying to overclock my P4 2.4C (with HyperX PC3500 RAM), but I'm not able to get any higher than about 2.7 GHz because the DDR frequency gets too high, even if I lock it at 400 MHz in the BIOS.
Is there a setting I'm missing? Does the board automatically set the ratio if the system bus is set high enough?
Help would be appreciated, thanks.

I think that the key here is going from a 32 bit to 64 bit computer operating system where Premiere Elements 11, 12, or 13 can become 64 bit application in a Windows 7 or 8.1 64 bit computer operating system. The increased computer resources implication of that should increase the frequency of getting the larger project taken to a successful complete more than before. A lot of this has to do with multitasking potential.
Premiere Elements does not support CUDA as seen in high end video cards/graphics cards. Since Premiere Elements 9, Premiere Elements has no GPU accelerated effects. But, I would decide on the best card for you based on overall computer rather than just for use in Premiere Elements. If you are interested in computer games, that will impact your card decision.
The use of a non super NVIDIA or ATI card should work for you. But, I have used neither.
I would consider more installed RAM, depending on your computer motherboard slots.
You might want to discuss the choice of the card with NVIDIA.

10x memory ratio on MSI Pro E

I just built a new i7 920 system with 1333mhz DDR3 ram and an MSI pro e motherboard. In the bios the memory multiplier is set to auto and the ran is running at 1066. Since the ram is rated at 1333 I should be able to change the memory multiplier to 10x in the bios correct? When I went to the bios the max memory multiplier I found was 8. Am I missing something?

I want to see what people are getting as far as FSB. This really isn't to see how high you can go with your CPU but how much FSB this board can be stable to.
Reason being, I think the CPU to RAM link on this board is not really that great. and I'd like to get a list of what people are getting.
Note: You need to be able to pass Prime95 v25.6 torture test "In-place Large FFT" for at least 4 hours. on all Cores
in-Place Large FFT requires that CPU, RAM, and the CPU-RAM link all be stable.

If not, then I need some recommendation for a low profile (low hieght) HSF that's quiet - quieter than my stock HSF that came with my AMD 3000 XP.
This is not the computer in my signature below - it's for a friend ;-)
Thanks,

I don't think so, but if you add an 'A': Zalman CPU Fan Socket A/478/754 CNPS7000A-Cu.
Be very careful! It is much heavier than recommended. And it IS a bit tricky to attach. But when finally there it does a marvellous and quiet job. Zalman's site is a bit difficult to search in the way you would like to:

This sounds more like a poorly seated heatsink, or lack of thermal paste.
You say that you had the same issue with both boards/CPU's, so that makes me think the heatsink is either not fitting correctly, or has no thermal paste/pad in place.
After putting the CPU on the second board, did you clean the heatsink, and reapply thermal paste to it? Once the heatsink has been removed, fresh thermal paste must be used.
