SOYO KT600 and XP 2700+

[lucid]

Hey peeps I want to pick some of your brains :)

My PC

Soyo Dragon KT600 Ultra Plat
XP 2700+
2 x 512 Geil DDR3200
Power color 9800se
Zalman Reserator cooling.

I am an OC noob so bear with me.

I have achieved 2.4 GHZ with a multiplier of 12 and frequency of 200. I set the CPU voltage to 1.75v and it is stable at about 43C.
I have the ability to up the frequency in 1mghz increments and I was able to get to 215 and the PC did boot. But, when I ran 3d mark the program would crash to windows.

I also tried setting the multiplier to 10 and the frequency to 240 to try and get to 2.4 by increasing the FSB. PC wouldn't even boot.

Are there any other things I could try or is 2.4 the most I will get out of this chip and mobo?

Also can some explain the agp:ddr:pci dividers and what exceptable settings are.

Thanks!

Hi there.
I belive the problems you are seeing are simply due to lack of volts, both to the ram and CPU. This is still a debated issue, but i think that 2.1 V is quite safe for everyday useage.
The dividers are to keep AGP, PCI and DDR frequencies within their operational parameters.

Im assuming you've found the divider for the pci to be 1/6 of the fsb 200 * 1/6 = 33.33Mhz (native PCI bus speed). I dont think KT600 baords have any available after that. So you maybe hitting your wall by driving components out of spec. You can do a bit of fsb raising anyways before you get into trouble but 240 would be very difficult. Phitz about with the multi and go a little easier on the fsb than your 240. Unless you can find another divider to bring AGP to 66 and PCI to 33.

Thanks for for info peeps!

I think it may be limitations on my mobo. If I was to get a nforce 2 board whats the best out there for overclocking? Is the lanparty good?

i think so. :) i like it... but it depends on personal preference.

if you want good high total clocks and lower FSBs, get Abit NF7/s.

if you want low total clocks and higher FSBs, get DFI Ultra Infinity or Lanpary B.

Do you know of any good sites that explain the pros and cons of FSB and CPU overclocks?

[IamAnoobieCheez]

For head to head Abit nf7 vs. DFI Infinity/LP b article, i haven't seen it yet... maybe i didn't look hard enough. :D

Here are few of the discussions that talked about these.

The URL below is one of the older threads, and contains some outdated information. Part of the "possible problem" is that the DFI runs at 50mhz AGP by default unless you manually change it to 66mhz. I had clear gain of 150 points or higher by setting it to 66mhz. There are so many things in the BIOS that can impact your performance. The DFI has a lot more memory options so it maybe confusing to some new people. Abit NF7 also has very good performance for its clock. They are pretty much neck to neck in performance clock for clock, but the DFI boards slightly edge out due to overall fine tuned memory subsystem. Like i've said, the Abit does better at higher total clocks though. The Abit board is more Vcore-friendly so you can take advantage of that.

Also, Abit boards(recent release) is very picky about hardware. They don't generally like double-sided winbond BH-5 sticks for FSB oc'ing. If you get out of luck, you might get stuck at way under 200FSB, now that's with intensive setting though. If you loosen up all the settings, it'll go up higher. Abit also likes certain CPU types/models. It takes lots of modding to get the boad to like it so you can up the FSB to a descent level. Though if the board just simply can't accept the memory sticks, it will fail in FSB oc'ing no matter what you do to it i.e. vdd modding, vmem mod, psu modding, L12 mod, supercooling the NB, etc will gain you zero FSB. But if you run into memory sticks that is liked by Abit board, you will get great result in FSB overclock. With mods, right CPU and memory, 230FSB+ shouldn't be a problem.

DFI board is not picky about hardware. It accepts virtually any damn kind of CPUs, memory sticks, etc. As long as the memory sticks themselves are able to handle high FSBs and tight timings, the DFI will be able to attain high FSBs of 240~ 250+FSB at super tight timing and at full intensity in the memory department, which results in superb performance. Again, relaxing the memory setting will increase the FSB oc further, just like Abit's and any board for that matter. The DFI boards however, is not so good in voltage regulations. Vcore is limited although it has much better vmem voltages. The Vcore is maxed at 2.0v and performing the Vcore mod will not likely to bring good results. That explains why the it suffers from top clocks. FSB overclocking and stability in this department is excellent though. The board comes with a CMOS reload feature to take advantage of.

they both have mounting holes for waterblocks btw..

Can the core voltage on the Lanparty go higher than 1.85 and whats the max manual cpu frequency?

Also do all motherboards handle APG/DDR/PCI speeds with dividers like the kt600 does or can you manually set them?

yes, the Lanparty has upto 2.0v core in bios.

the FSB is upto 300fsb in bios.


with nForce2 boards(including Lanparty) are locked at 33.33mhz PCI. The AGP bus is selectable, you have control over it. You can set it to 66mhz if you want. It is changable by increments of 1mhz from 66 to 99mhz.

These nForce2 boards have CPU : DRAM ratio dividers for you to choose. 1:1 is sync.

Maybe I am just confused here but my KT600 can be adjusted from 100 to 501 FBS in increments of 1. I was told that your actual FSB is double what you set in BIOS. So if you set 200 then your FSB is actually running at 400. Is this true? If so is it the same with nForce2 boards? Can the FBS run as high as 600?

That's the basic. The DDR platform puts out a double data rate of the FSB. yes... same for the nForce2 boards. Since we are talking in the overclocking field we try to go by the initial FSB speed i.e. 100FSB instead of 200FSB DDR. you will also find most of us talk that way as well. I don't like fancy numbers like "oh! mine runs upto 500 FSB!! it's fast!! LOL" i don't like that.. let's stay with 250FSB instead. :)

Cool thanks for all the info. I test ran my chiller last night and my water block got down to -38f in about an hour. Was still dropping but I shut it down. I am trying to learn about all this stuff so I'll know what I am doing when I setup my chiller :D

BTW, who is the girl in your avatar?

Great! Happy to help.. Sounds like an impressive phase change cooling you got there. Up for some nice clocking.. :D

If you do decide to get the DFI nf2 board, I'd suggest you flash the BIOS to 1-31 or newer (for both Infinity and Lanparty) so you don't run into Low CPU temperature boot issue. Whatever the board you choose, wish you good luck. :)
